something you might find useful for future things, when you need to stick a patterns to a sheet of metal, etc. put down a layer of masking tape (aka painters tape, etc) first then glue the pattern to the tape, means that when you come to take it off it easily peals off with little to no cleanup needed after.
That's a great idea! I'll use that in the future, for sure!
It’s so awesome to see how much you love your dad. You always refer to everything he’s done or given you with such respect and gratefulness. You’re a very loving and caring person besides being funny and intelligent. Love your channel.
Thank you for reading our comments! Hope you have a Happy Thanksgiving with your father and all of the ones who love you! Illusion your cat!!
I like how you show things in real time and talk about RPMs. I have the same lathe as you and it helps me get the feel for how it should sound and look.
I really appreciate that! I intentionally show things at normal speed to help communicate the pace and feel of machining to people who want to learn.
I grew up near to RAF Northolt in West London. I often heard the sounds of the Battle of Britain flight ( Spitfire and Hurricane) flying over and around my parents house!
Brilliant! I love how everything you make involves different techniques, from drilling before slotting to the correct use of a file.
The method of filing used to create the end radii is exactly the way I was taught to do it. This was way back in 1974 when I started my apprenticeship with Rolls-Royce in the U.K. Just an observation, but would a small lead-in chamfer have help start the thread in the studs. Subscribed.
I really enjoy your subdued, matter of fact style of presentation. Nice!
Thank you! 😁
I need to do basically the exact same job . I'm a luthier not a metal worker so my kit is a bit limited although I do have a mill and a lathe. I'm loving the fairly basic tool set required for this project. Your clear concise and complete style of presentation is killing it. Keep up the good work!
Thank you very much! 😁
Isn't a lathe user called a "lathier"? FWW, it took three corrections to get that past autocorrect!
I like the way you work. Your thinking processes are very clear. First you design a part that will work that you can build with the machine tools that you have. I don't have all the machine tools that you have so I have to follow the philosophy of "Design what you can build" vs. "Build what you can design". A lot of ads for machine tools give the impression that you can use their tool to build anything you can design which isn't true. And even if it were it doesn't mean that it will work or that it is the best way to do something. A good machinist is also a good designer and good at designing for manufacturability.
I planned to make a better rest for my grinder, and your video gave me many hints, and what could go wrong. Thank you.
I have never seen someone make things so much more than what they need to be... I love it. Just found your channel and love your vids. Thank you for Sharing everything.
I've thru all your videos on lathe basic operation, and they are very pleasant. This one is also a great video. Strong acknowledgement. Greetings from Geneva, Switzerland
Thanks for watching! My family is actually from Switzerland. 😀
Looking forward to the next part. Thankyou for a great Video.
Fun project, thanks for sharing!
I really like when you do projects like this. Great video! Thx for posting.
Great, thank you! I really like doing the project videos myself, although judging from the view counts, the internet prefers my educational ones. 😀

Looking forward to bingeing on your content.
Awesome! Welcome to my channel! Glad to have you. 😀
I grew up in a machine shop my father was a machine salesman everyone in our family knows how to run machines, including my sisters you would get along well with my oldest sister... Well done video looking forward to part 2
That's awesome! Would love to meet the whole family.
Nice to see a press fit technique being shown, looking forward to the next vid.
Thanks for sharing,
Cheers
Press-fits are very satisfying. One of my favorite things to do in machining. 😄
Great video. Refreshing presentation. Well done!
Am developing a burning desire for a mill drill, thank you.
Are you in heaven? Machining while the sounds of. P51 drift through the workshop?! Oh Lord…bliss
Hi Quinn, nice to know that something I do seems to be the right way, I don't remember being taught (last time I was taught anything metal was bout 47 years ago) the filing. Useful tips with the drilling before milling especially with the DRO line function. TFS G :)
Great project! I've been contemplating doing something like this to one of my grinders.
My goal is a larger and more ridged work surface. I was thinking about one large tool rest that spans the entire width of the grinder. This would make it easy to get two attachments on the plate to prevent twisting and make it more stable. The downside to this arrangement is that compensating for wheel wear may be an issue.
I look forward to seeing how your design performs.
Thank you, I'm a new subscriber and home amateur engineer. And real one too. I thought it was just us Brits that mixed metric and imperial measurements. I loved "5 ten thousandths bigger than M4.." so 0.0005 is 0.0127mm giving 3.987mm..so after all that I'm saying you used a 5/32 drill. Or 156 thousandths as you lot seem to be fond of saying.
Carl Wilson Both in the US and in Canada, you pretty much have to be comfortable with both systems, I think. Despite most manufacturing being metric, you still encounter both systems on a daily basis. Salute to the Commonwealth! 🇨🇦
Thank you for your reply. I didn't realise you were Canadian. Oops! My apologies. Yes I agree, in the UK it is perfectly normal to walk into a hardware shop and buy a 3 metre length of 4 x 2. We use both systems and despite having officially converted to the SI system of units in the early 1970s, the imperial system is still in everyday use. I'm looking forward to the next installment of the grinder rest. I very much enjoy your content. Salute indeed to the Commonwealth! 🇨🇦🇬🇧
12:21 - "milling is fun" - hear hear!
14:20 - lol!
[My binge of this channel in chronological order continues! You posted new content... had to get back to it!]
Thx for the filing tip.
Thanks for showing, me last week decided to see how my woodwork belt grinder grind HSS toolbits(12x12mm) and to my surprise it does well and somewhat cooler grind. You have to hold tool with one hand on a 7-8 degree set rest at the side angle you want from the side direction you want, and use a handstick to press hard around the tooltip with your other hand.
Following this I am now making a proper adjustable toolrest which is part of a jig that clamps in a vice on workbench and holds the woodwork bosch grinder in upright position belt going down.. On the adjustable pice about 120mm x 70mm fitted with lock down clamp like alternator adjustment I have to come up with a milled support piece that goes around grinder to grind the top rake angles-I may have to revert back to the benchgrinder here, will see. Not using the bench grinder for the side angles is a relief for me and I got better control and its faster. So next week after making an aliminium push stick with screwin metal tips to hold pieces of thick leather dipped in water to warn when tip gets hot(steam),... I will know if this is going to be my new preferred way of grind.
Nice tool upgrade Quinn.
Great shop project. I’m looking forward to seeing you do the press fit. That’s something I’d like to know more about.
I'll be doing a video on fits and tolerances, actually, so stay tuned for that!
Good job thanks for your precious works
Excellent job.
What a great teacher, thanks
I should be studying multi-variable calculus and differential equations. Quinn, I blame you for whatever happens tomorrow. Strangely addicting channel!
I’ve been called strange a lot, but never strangely addicting. I’ll take that as an improvement! 😉😬
Quite enjoyable as usual.
I also use Imperial wisps and smidgens.
I'll try the radius filing technique. I always went the other way, but your way seems less awkward.
Thanks.
Meow to Sprocket.
Sprocket says, "meow" 🐈
I see you are quite methodical in your processes. Excellent attention to detail.
I'm back, I still need to make this steady rest.
Great project. I have thought about making a rest that mounts to the base of the grinder because the guards on my grinder are really flimsy. I think this is the inspiration to get started.
Thanks for posting such great content.
Yah, I think mounting to the base is a better choice if you can. The way this grinder is, it was going to be really complicated to do that. Reusing the factory mounts was easier, but it's not as rigid as I'd like. Stay tuned for more talk about that.
Robert Oswalt, my grinders are bolted to plywood bases, which have their own soft rubber mounting feet (blobs of silicone sealant.) Tool rests and other accessories mount to the base, this allows for lots of options as I use a standard base on them to pick up 2 studs fixed in the base.
I want to do something similar on my wet grinder but the tank that covers the bottom of the grinding wheel is made out of plastic so I will have to think about it some more, thanks for the inspiration,back to the grindstone as it were!
You have a wonderful channel and are very talented and gifted. very gifted teacher !
Thank you! 😁
We are completely on same page with crappy too rests on grinders. I searched one day on Amazon at the massive collection of grinders and they were all really poor until you got to the $1000 range. Insane. This video was chock full of tip goodness. You improve with every video, if that is actually possible.
Aww thanks! I hope the whole series turns out okay.
Exactly the kind of project I was looking for! My grinder sux too, and I just got a dozen pcs of HSS....
Cool! Stay tuned for the whole series. I hope it'll be helpful.
You don't see someone filing a radius the right way this days. Great! Keep up the good work!
Thanks! It's so much easier this way! 😀
'Pask Makes' sent me!!!
I like the bulk removal with the drill.
I like the way you do it. 😎👍👏
On the side of my grinder..I drilled a hole through the rt side and added a 1/2" drill chuck for arbors and such
Great idea, awesome job. A rear lathe [spindle] spider would be a great future project, too. Lol. Again, Awesome job.
eddie Towers That’s a great project idea! A lot slicker than stuffing a rag in there. 🤣
That what you did, was a cool MacGuyverism. Using what you had on hand. I have never thought of that, which is too bad, considering how many times I’ve had napkins, with lunch,, thinking, “Man, I’m going to need something to hold that rod on the back end of the lathe spindle”, while wiping my hands after eating a panini
@@eddietowers5595 machine grease, panini grease... whatever works. :D
@@DavidLindes YESSSS! This guy gets it.
eddie Towers 😁
Should make a foot switch that you stand on with one foot to make your life easier in case of those little bits getting stuck as you said👍🏼
I'm enjoying your videos, thank you. With the band saw you could try a zero clearance board clamped to the table to prevent small parts jamming the blade. Just a sheet of ply or mdf cut with the saw blade to the middle and clamped down.
Steve Kingsley I do indeed do that sometimes as well, but I wanted to call out that risk for people who may try this table for the first time.
Hi Quinn! Great video! I see you keep your diamond dressing tool in the quench tank. So it’s always ready, but you can’t cool off the pieces you’re grinding! Maybe make a bracket for the dressing tool and then you could put some water in the little tank. Just sayin’.
Craig McCuistion That’s a holder for the dressing tool. The dunk tank is down in the base (you can see the rust in the bottom of it)
GOLD STAR for correct use of file to define a curve! Second gold star for disseminating truth.
Very nice video
I'd legit never seen a variable speed grinder before your channel, last night, and I think I am a bit envious now. It seems like such an obvious idea...
Outstanding
@11:54 you forgot: "Yahtzee".
Great video as always! Thanks!
This is going to work very well.......congrats on 5k subs
Thanks! 5k is pretty nifty. 😁
Blondihacks wow, from 5k to 76k subs in a year!
That "toothed-wheel" arrangement at about 1'30" is actually called a Hirth-coupling. In days gone by some motor vehicles' engines had their crankshafts assembled with Hirth couplings. If one uses high-quality materials and high-quality machining processs it forms a very precise, repeatable and non-slip joint. The only downside it that it's expensive.
Good to know! I was not familiar with that.
Wow! Did I just saw a pink tool box?!? That is 😎 cool. Anyway. I again love how you explain things. You and Old Tony are my favorites. Btw, since you are so explicit, I would easily see you video teaching 3D drawing for hobby machinist like me. Think about it…
First off, absolutely enjoy all your videos. Subscribed after the mention on Abom79, and no regrets. I like the easy pace and the relaxed tone. You are very much better than the "CZcams Hack" you keep calling yourself in the videos.
Second, and this is just an opinion question, why did you choose not to knurl the pins that would be pressed in? I presume because the drill rod is hardened? I'm unsure if 0.001 press fit would stand up to regular tightening and loosening of the thumb-wheels, but that may be my lack of knowledge showing itself. Just curious.
Great question! Knurling is probably a good idea. I use Loctite 603 on light press-fits like this, and it's impressively strong. You'll see that in an upcoming part of the project. If it doesn't hold up over time, I'll remake the studs with a larger diameter for a more aggressive interference fit.
I was going to ask about Loctite, but didn’t. Fair point. I also thought you might not have a set of straight knurling wheels, since pressing in a cross-hatched knurl would not make sense. Either way, looking forward to the next installments.

Nice
7:40 Tedious, yes, but not as tedious as milling from scratch I would say! There are probably a million different designs for rests out there and they are all good, just depends on what you need. Cheers Quinn!
For sure! Saves time, and drills are a lot easier to sharpen/replace than milling cutters.
i came across this channel through abom79! and what an excellent channel it is. clear, precise, educational, and entertaining. another youtube joy!
Aww, thanks! That's very kind of you to say. ☺️
@@Blondihacks No avoiding it now, I think you're stuck as part of The Machine Shop Mafia! ^_^
Hello Quinn, I have the same grinder, I know what you mean about that little crappy table, I have been wanting to do something similar to what you are doing, keep the great videos coming 😃😃😃👍🏼
Great! I hope you find this series helpful! 😀
That is the PINKEST toolbox I have ever seen!
It is very pink indeed. I got it on sale, free shipping. That's my excuse and I'm sticking to it. 😬
Awesome job and a very interesting content, but we want more about your cat!! =)
To stop the small offcuts falling into the bandsaw, perhaps try a magnet glued to a popsicle stick. Attach it to the part that will drop before severing from the larger piece. Maybe flexible magnetic sheet (fridge magnet) would also work.
Edit: please have a look on YT for "Lathe Bar Stock Accident - Whipping at high speed" so you can see a consequence of having too much stock sticking out the back of the headstock.
Darryll Crook The magnet is a great idea! Just placing it near the blade might be enough to grab the small pieces and pull them out of trouble.
a 1/4-20 endmill is what you get when you bump the x/y axes while tapping!
LOL. Very true. 😄
Abom sent me.... I like watching your vids..... keep doing more.
Thank you!
Love the Pac-Man.
Second and first to like..😊 I have had that exact project in mind for a couple days now thank you
Excellent! I hope these videos will help out.
If an Individual (like me) doesn't own a Mill, is there a "Budget Freindly" X Y Clamp/Vise that you would recommend? I own a ¾HP "ROCKWELL/DELTA" Drillpress that I aquired from my Father's garage tools as he was an Engineer for BOEING for 45 years.
I have seen quite a few with incremental dials, but am insecure regarding their reliability/accuracy, but I am not financially sound...
Also, I would like to add an active Oiling System to keep the Cutting tool and Material from "melting/galling", as a "Shade-Tree" Machinist, what would you recommend? I would have no problem adding a Transfer Pump with a Filtration System so that I can "reuse" my cutting fluid.
I just happened to "stumble upon" your Channel and absolutely love your demeanor and attitude! I would ask "FIREBALL TOOLS" but he is busy with "easy questions".
Thank you,
Thomas 😸

Man I don’t know what it is about a chic talking about slots drilling and mounting ohh boy! Why can’t my wife be into machining like this!!!
CBN wheels don't need dressing, run cooler and you can safely grind on the sides
How about a short video on how you keep your shop so embarrassingly clean?
Hi Quinn! What bench grinder wheels, grit, etc., do you recommend? Amazon links? Thank you for all the EXCELLENT content!
what kind of milling machine do you like for starting out? i just bought a High torque mini lathe 5200 from LMS
/
I think that's a great choice! With machine tools, the right answer is usually "the biggest machine you have space for and can afford". The LMS 5200 was a close second for me, after the Precision Matthews PM25 that I settled on.
Change wheels? Never,buy a 2nd,3rd, etc grinder. Presentation,sound and video ,great..!!!!
Someday I will, when I have the space. For now, I have to change wheels. 🤷♀️
@@Blondihacks No offense meant,I went with one,but, when switched to 2 then 3 made shop work so much pleasanter and faster. The right stone,right away.
No worries! You're right that multiple grinders is the way to go if you can.
You don't think that eighth inch thick slider bar will be a little bit floppy? That's one of the first things that I dislike about most factory grinder rest s is they have a little flimsy track and the whole thing seems vibraty. I like them chunky.
What kinda stone is on the grinder to grind tool bits?
How did you make sure the two sides of that bracket were parallel so you could securely hold it in the mill vice?
You SAY it's tough to film near a historic airfield. You must mean it's AWESOME to film near a historic airfield.
P-51s flying overhead? Sign me right the hell up
They are pretty amazing
First!!! Never been first before. Anyways, love the way your present your stuff. I'm a home-shop machinist and a lot of channels come off pretty condescending.
Congrats on first! 😀 Thank you for the kind words- I am going for a friendly approachable tone, because that's what I was looking for when I started!
Maybe a question alot of subscribers don't ask, how do you "dress" your Grinding Stone?
Nice to see some standard imperial wisps getting eaten by pac man! :D
Omnomnom
I looked in my junk pile but could only find timber 🌲
you must have had the same shop teacher for filling radiuses. start with file low and end up high
I honestly don't remember where I learned, but it does seem that a lot of folks don't know that one!
Ah, "janky"... technical terms, I love 'em. :D
"Janky: (adj) 1. Designed by committee"
@@Blondihacks All too often the case these days. I like your updated design, it will be interesting to see if you find the 1/8" riser a bit flexible.
@@rennkafer13 Spoiler alert- the riser is great, but the sheet metal shroud it is mounted to is more flexible than I wanted. We'll remedy that, though.
@@Blondihacks I'll be patiently awaiting that video too. :D
I wish the airport near my house had p58 mustangs flying in and out
Are you using a 15mm speed handle on your mill vise? Been looking for one but all seem to be 3/4” hex for the 6” Kurt vises.
Right? It’s a 9/16” speed handle, and a guy here in the US makes them and sells them on eBay. Can’t recall his name, but a search should find it.
It’s an upgraded 5” vise purchased from Precision Mathews for my PM932PDF. It’s definitely 15mm. I’ll see if this seller has the right size. Thanks. You’re awesome.
Spax man Yep, I have the same vise. 9/16” is about equal to 15mm and he makes the handles specifically for these 4-5” import vises.
Great vid as usual...commentary perfect....
Still can't shift those damn 2 thumbs downers....grrrr!
Keep going gal..👍🏽👍🏽
Thank you, that's very kind! 😄
Hi Quinn,
Just a little bit of feedback :)
Can you stick to either metric or imperial in the same sentence please?
"5-10 thou than an M4 screw"
That works out to 3.873-3.746 mm which is non-standard size. :)
I think a 3.5mm drill bit would of worked just fine this situation.
Regards
flagmedownmedia Mixing units is pretty unavoidable, in my experience. The factory mounting screw is M4, and all my tooling is Imperial. I work back and forth in both all the time- it’s the world we live in. 🤷♀️
Hi Quinn,
Just wondering if you share your files on Fuson 360?
My Patrons have access to them, yup
Love your videos... how do you get the parts colors on Fusion360?
Shift-N
Got it
thanks...@@tunnelvision9549
what is a spring pass?
Fun fact wd40 is also good for grease and oil stand in clothing
If you point that file North then smack it with a hammer it will demagnetize.
I came over here from Adam Booth's channel when you sent him that "thing". I find myself wondering where you live. Your accent and occasional choice of words tells me the part of Canada that is in western Montana near Honolulu, but your name says Ireland. Who are you, anyways?
Paul in far western Oregun. (It hasn't gone anywhere.)
