Boeing surplus ! Talk about bringing back memories! I was, just today, 'salvaging' some 0.01% resistors from a 1960's vintage ballistic computer...from Boeing, or Radar Electric? Remember them? The cool stuff that you could find at Boeing was just amazing...strangely-enough, I ran across one of tbe Boeing surplus guys running a little restaurant in Bluff, Utah...Bluff ain't so big, and this place wasn't even on the main road, but we wandered in there...talking about sun, andntans, and 'we don't tan, we rust' , and that lead to discussion of Seattle, and...must have been 'twin rocks cafe...'
That is pretty funny, the world is a small place. Wonder what happens to all that great junk they surplus? One time when I was there they had a Monarch 10EE, in pretty nice looking condition. Bummer it exceeded my hand luggage allowance.
as always, informative AND entertaining! Your recent video on disassembling your lathe chuck inspired me and I pulled my 3-jaw apart tonight and it is soaking as we speak. It's a 1000 year old Boxford, but as long as you don't want precision, or speed, or surface finish, or repeatability, it's gold! Again, love your work and your videos!
Oh man, I LOVED Boeing Surplus! Being a kid from a Boeing family, I’d occasionally get the coolest (to me at least!) surprise gifts if my parents happened to swing by surplus. Huge sheets of scrap aluminum, tools galore, weird electronics, rolls of airliner grade carpet, so much great stuff. One Christmas, when I was ~11 years old, Santa delivered big-time. I was the proud new owner of several huge rolls of 3” & 4” adhesive backed aerospace-grade velcro, both sides included! When you have a couple hundred feet of ultra strong Velcro at your disposal, you’re only limited by your imagination. It was a sad day when Boeing closed the surplus store.
That is a cool story. I only ever went there twice, but my suitcase back to europe had blocks of 7075-T6 Aluminium, some T profile, some countersink microstops, a couple of end mills, a Digital indicator etc. Only place I ever saw a Monarch 10EE lathe, and it was for sale.
It really was an amazing place. You never knew what you might come across. Unfortunately, it closed while I was in college, years before I would have the ability to start making my own home ‘shop’ space. As a teenager, I was able to do some decent interior sheet metal repairs to my MG with materials from surplus. Boeing surplus struggled to remain financially viable for the company. Even though they recouped a tiny amount from the sales, the overhead staffing costs were huge by comparison. As Boeing became more LEAN, and waste materials were reduced, the surplus store had less and less to sell, which made it even less cost-effective to keep running. Eventually, they closed the store and shifted to bulk auction sales. I understand it made the most financial sense, but I’d bet that surplus store inspired/boosted the STEM careers of thousands of kids in the area… many of whom (😉) ended up working for Boeing or various suppliers in the region.
@@syf13 I also wonder what the indirect effects of a place like that are. In Boeings entire budget, the surplud shop costs must have been a decimal point on a rounding error.
The boeing surplus store was great. I have a bunch of endmills from there myself. Unfortunately they closed it like 10 years ago. Recent found your channel, great content, keep up the great work
Thanks for joining. I wonder why they closed Boeing surplus, and wonder what happens to all the stuff now? Only time in my life that I have seen a Monarch 10EE lathe was there.
@@RotarySMP Here in the PNW, you find Boeing stuff being sold at industrial auctions, or liquidators on Craigslist. That is how I got the Roll-In-Saw sitting in the corner of my shop that I haven't had the inclination to rebuild yet.
Renton Washington? Wish I was wanting to get into machine work when I was like 20yo so I could have picked up some of the older machines and stuff from all the closed down metal work shops here. I'm sure there are cool things still around, just harder to find when the only people I know who are into lathes / mills / shapers, etc etc are here on youtube lol.
When I lived up in seattle, Boing surplus was a regular stop for me and a mandatory stop when friends came to town. If only I knew then what I know now....
Probably. I lost that first one right at the end of stripping down the Maho, and given this is a small space and I am the only one working in it, cant for the life of me picture where I might have hidden it.
The actual tungsten carbide may not be harmful, but cutting tools are "cemented carbide". The carbide grains are fixed together with a binder metal, which is typically cobalt. Cobalt dust- don't breathe this!
Ye i was sick 3 days after i sharpen my carbide tooling for the first time lol. I would compare the sickness to welding galvanized steel. They both SUCK
There can be Cobolt but the binder materiale is Nickel. Cutting tool for metal has typical 6 % Nickel and tools for woodwork 8 % to make the tool more ductile. Always use mask when grinding also the grinding wheel will release particles.
Thanks for pointing out Drills Taps & Dies. Good material there! Jeremy next. Edit: Some years ago I visited Pratt & Whitney’s surplus store in nearby Windsor Locks; I recall quite an admixture of cool stuff. I guess it’s time for a fresh visit, if the store still exists.
@@RotarySMP According to a local online news source, the P&W Surplus store closed in 2010. 🫤 It had been in East Hartford, not Windsor Locks; the latter is the home of the old Hamilton Standard company. Oops
Boeing is watching. Lol currently work at Renton Boeing. There's still a surplus store. Not quite like the old days apparently. But still plenty of mill bits and odd ends
My nephew was supposed to have a payload on that space launch before the pandemic shut down the world. His project was then scrubbed. We'll see what happens to that. And nice work! Someday I'll have to get a tool grinder.....
Hi Jasper. That must be a disappointment to make a space ship and then have the project cancelled. Hope it still flies. T&C Grinders are a lot of fun. I considered making the Stent grinder till the Clarkson fell into my lap. Did you see that leak on the FDR readout on the China Eastern crash?
@@RotarySMP I hope he gets to space as well. I understand about the Clarkson. Also, I have not seen anything on that crash. I just know that airliners don't crash like that.....
@@jster1963 It looks like pilot suicide is on it's way to becoming the #1 cause of commercial air transport fatalities, as all of the other causes like CFIT, technical failures etc are minimized.
Nice work on the cutter Maybe a spring to the base would help with the collet-closer when running it without the housing installed? (requires then a red tab "Remove before cover install")
Hi Jeremy, I hope that gives you a traffic bump. You are doing a great channel there. Do you regularly go magnet fishing in a river next to a scrap yard? I cant believe the varied cool scrap you have in that drawer.
It’s been a pretty big bump. If you weren’t on another continent, I’d send you some rusty cast iron scrap to melt as a thank you. I’ve actually been watching your channel for a while now, just don’t usually say much.
@@JeremyMakesThings Glad that it made a difference. I also had a couple of decent bumps due to shout outs from guys further along this track. You deserve it.
In the future it might be simpler to just grind the existing endmill flutes into the angled cutting faces. I work as a CNC tool grinder and we turn customers old used endmills into chamfer mills all the time.
Very nice job, didn't expect to see a Clarkson mk1 in deepest Europe. ( I did note it last week) Mine, needs a motor and new pulley fitting. Thanks for sharing.
I got this from a mate here, as he moved up to a much bigger TOS T&C grinder which can do everything. You will love it once you get your Clarkson running. Fun tool to consume endless time ;)
Yeah, Stefan makes it look so easy. It took me hours, for a lesser quality :/ There are a number of none- functional surfaces on the Schaublin tool holders which are ground. And the surface finish is flawless. I hate to think what this stuff cost new.
I have like four of those German 30/32 hook spanners that came with my mill, can also never find one when i need one. On several occasions when looking for one I've check a spot in the shop and it isn't there, check another spot and go back to check the first spot. After repeating that like 3-4 times it always shows up at the first spot. They're friggin cursed I'm tellin ya
@@RotarySMP ya, my youngest went through a pink phase, and I painted some walls pink in her room, and now as she approaches 18, it's all been covered with a black and dark blue. Nothing lasts forever. =D
In your last Video you mentioned that the pneumatic hose at the collet spanner keeps breaking. You could put a "Schottverbindung" (sorry dont know the english word) in the pneumatic hose, roughly where the bracket which clamps onto the hose right now sits. When the hose breaks again you can just swap out the broken hose (which would be only be roughly 300mm long) and dont have to reroute the whole hose through entire the lathe. This could save you much work in the future and also alot of money, when you just have to throw away short pieces of the pneumatic hose.
So far it only broke once, and that was because I didnt give it enough clearance to the rotating piston, but yes, I will fix it by adding a union there, rather than replacing the whole tube.
@@florianhaus7481 Yep, I got it. Once I looked at it and saw I'd need to pull the main motor back out to replace that line, I already decided to join it.
Really nice work on that cutter Would be curious if you feel qualified to speak on general private aviation, cost of entry, typical age of GA pilots, how to make flying affordable and interesting to younger people, etc etc. Curious to hear the thoughts of someone who clearly has a rational head on their shoulders! I follow some of the new GA planes being developed like DarkAero and similar, but I assume the commercial side isn't as tuned into the builds or development.
The economics are very difficult. The certification works, as soon as you have software (what doesn't these days), it gets very expensive. As soon as you want Night VFR--> IFR, you are into DAL (design assurance levels) for the software cert which litterally cost millions. One result of this is the lack of good certified electronically controlled engines.
The cutter came out nice, especially considering all the mucking about. 😃 Mark, You’re a true renaissance man. With that established, any chance that you know the technical reason for the 100deg countersinks in aerospace, as opposed to the typical 82, 90 or 100 degree? 👍👍😎👍👍
Thanks Joel. The Clarkson is a black hole for time. I can see it being really fast for repetitive jobs, but who has them? That is a good question. I dont know, but to hazard a guess, I would guess that research was done which identifed 100° as giving the best compromise of strength and weight in aluminium, especially considering that many skins are thin, and therefore dimpled rather than countersunk.
@@RotarySMP no magnets, though I may try to do some snorkeling this summer. I’m going to try to do a video on where I find this stuff sometime, but you know…projects.
Great video! Crazy to see how for its come along, its really a beautiful machine after all this work Would you mind sharing what type of toothed belts you got? I plan on using toothed belts in my lathe build, and Ive see that belt used by This old tony and a few others but not sure what they’re called. I would have put out my next video a few days ago but after a long series of…. Learning opportunities…. it ended up taking way longer than expected to get much content to make a video on. Hopefully it’ll be out today though!
These are T5 x 61 tooth, one is 25mm wide and the other 32 wide. These are direct replacements as I am retaining the original pulleys. If I was doing it new, I would probably use HTD form. Keep the videos coming. :)
@@robertsteinwandel6658 I had never really considered doing video before, although I always was into photography, but the editing software, phones and cameras have made it so accessible these days. It has been a fun journey.
grinding the chamfer tool to a point is pointless (pun intended) The resulting point would be fragile and have close to zero surface speed in use. A much better idea is to deliberately truncate the cone by a known amount so this offset can be accounted for when programming depth of cut for contouring operations. I believe Joe Py has a video on the subject.
Man that ultrasonic cleaner is coming in handy. What's your favorite plane? I found a channel on youtube rex's hanger, that talks about intra-war aircraft, the wild west of designs.
The most enjoyable aircraft I have ever flown are the Yak-52 and Bucker Jungman (only flown replica's). Those trainers have nearly perfect control balance, and reward precision in control. with excellent stick force curves, and aerodynamic feedback. Other mentions are Jodel D11, Vans RV-4, T-6 Harvard, and the Forktailed Bonanza. I like aircraft with precise controls. I didn't like the Cirrus, the 182, or Piper Cubs much, for their poor control balance, wallowing around, or for the cirrus, the spring artificial feel.
@@RotarySMP cool cool 👍. My father left the force while we were down in Woodbourn just the year before project Kaka started. The complete rebuild of their avionics ect. Modernisation program. Was so much more relaxed in the 80's. I can remember as a kid climbing all through and over them. No chance of that now day's. LoL
@@russcole5685 Project Kahu. It also, removed the Avionics hump (although adding avionics), reskinned the wings, and replaced a spar. I got sent over to wing team as a very fresh mechanic, to do an incredibly boring job for a week. Thanks for the reminder, I'll add that to a video.
I have recently found the channel "Huygens Optics" Check out his latest video on the process of machining a monolithic telescope. It blew me away! Also: I have bought broken and dull end mills on eBay for generally a dollar or two apiece....even carbide. So far I have only hand sharpened them but am working on making a grinding rig for my lathe. Especially for grinding radii on multi flute end mills, reamers and drill bits.
@@RotarySMP So far my plan is to make it similar to a ball turner for the lathe but with small arbor and holder for diamond wheels and bits with another angle plane so I can adjust it to cut relief on the radius of multi flute cutting bits.
@@mrspeaky6885 Oh, thanks for pointing that out. Maybe I messed up a setting, as I just notice that this video is only about a 1 gb file. Normally they are more like 4-6gb. Sorry about that.
I just watched a bit through youtube, and apart from the various focus errors I make, it doesnt seem to have worse compression artifacts than the others.
nice work!

The most enjoyable aircraft I have ever flown are the Yak-52 and Bucker Jungman (only flown replica's). Those trainers have nearly perfect control balance, and reward precision in control. with excellent stick force curves, and aerodynamic feedback.
Other mentions are Jodel D11, Vans RV-4, T-6 Harvard, and the Forktailed Bonanza. I like aircraft with precise controls.
I didn't like the Cirrus, the 182, or Piper Cubs much, for their poor control balance, wallowing around, or for the cirrus, the spring artificial feel.
@@RotarySMP how much time did you spend in the A4 while at Ohakea
@@russcole5685 I never got a flight in one. I spent about year on squadron maintaining them.
@@RotarySMP cool cool 👍. My father left the force while we were down in Woodbourn just the year before project Kaka started. The complete rebuild of their avionics ect. Modernisation program. Was so much more relaxed in the 80's. I can remember as a kid climbing all through and over them. No chance of that now day's. LoL
@@russcole5685 Project Kahu. It also, removed the Avionics hump (although adding avionics), reskinned the wings, and replaced a spar. I got sent over to wing team as a very fresh mechanic, to do an incredibly boring job for a week. Thanks for the reminder, I'll add that to a video.
Are you near Renton? I miss the surplus store there
No, I am in Vienna, but had a few business trips to Boeing over the years. Real shame they closed the surplus store. Greatest store ever.
@@RotarySMP if you make it to Seattle, reach out. BBQ on me
@@RyJones Thanks. I haven't been there since a 777 delivery back in 2007, but it is a nice area.
I cant find the ''Drills, taps and dyes'' channel you mentioned. Could you post a link?
Here it is. Did the pop up link during the video not work?
czcams.com/channels/pfSARUDd-ffAWPxBBIMauQ.html
I saw it :)
@@quicklistmovies Thanks for the feedback.
No problem. Loving the funky vibes.
@@RotarySMP Yeah did work, thanks for the link!
I have recently found the channel "Huygens Optics" Check out his latest video on the process of machining a monolithic telescope. It blew me away! Also: I have bought broken and dull end mills on eBay for generally a dollar or two apiece....even carbide. So far I have only hand sharpened them but am working on making a grinding rig for my lathe. Especially for grinding radii on multi flute end mills, reamers and drill bits.
Will you be making a video or posting a thread to a forum. I would be interested in seeing that.
@@RotarySMP Yes..HOWEVER...there is not going to be much precision about it. I can't do precision.
@@HanstheTraffer I was planning to make a Stent cutter grinder till a mate sold me the Clarkson.
@@RotarySMP So far my plan is to make it similar to a ball turner for the lathe but with small arbor and holder for diamond wheels and bits with another angle plane so I can adjust it to cut relief on the radius of multi flute cutting bits.
@@HanstheTraffer Go for it. T&C grinders are a lot of fun.
Is it just me or is the compression this time just garbage?
EDIT:Seems to be a problem on my side
Which compression? I don't understand sorry.
@@RotarySMP Video Compression / Bitrate
But i wouldnt worry about it until others confirm it maybe its just a problem with my browser rn
@@mrspeaky6885 Oh, thanks for pointing that out. Maybe I messed up a setting, as I just notice that this video is only about a 1 gb file. Normally they are more like 4-6gb.
Sorry about that.
I just watched a bit through youtube, and apart from the various focus errors I make, it doesnt seem to have worse compression artifacts than the others.
No compression issues for me and I’m sensitive to them.
