I found it to be much faster than tapping, and it would have been even easier with a better jack. I'm thinking about making one designed for the job. Thanks for watching.

Thanks Fergus :)

Thanks Carl. As noted, this was my first "proper" camshaft (Webster just had a single lobe made with two rounded ends and flat flanks). When I asked Greg how he would make it, he referred to a method that requires a cam machining jig. I expect that is a much faster way to machine camshafts - after you have invested in the jig. However, building a single cylinder engine with enclosed crankshaft and overhead camshaft was just an interesting challenge for me and I may not make any more engines. So while milling several hundred thin slices was a bit tedious, I think it was the best option for me. Cheers.

Some of the improvements were pretty easy to do James, so go for it! Thanks for watching.

Thanks Paul. The maths involved in calculating the tangential machining path are not trivial and I am very grateful to the person who published their solution :) Cheers.

Thank you. Like most things - easy when you are shown how to do it :) Cheers.

Thank you.

Thanks Henry.

Thank you Stephen.

It was a bit of a character test, but ultimately quite rewarding :) Cheers.

I'm easily confused these days Kit, so I think I'll limit myself to what I need to know about cams :) Cheers and thanks for watching.

Thanks Graedon. I didn't realise how much I didn't know about camshafts until I made this :) Cheers.

Hope you enjoy it :) Cheers.

Thank you Karl.

Спасибо.

Its that time of year and the possums are trying it on again. But three years on and the tree is noticeably taller; it is getting easier to prune off all the attack vectors :)

I'm glad to hear :) (I was making a joke about Possum Magic hahaha)

Thank you - it was a special moment that was very rewarding :) Cheers.

Thanks for your feedback Joe. Sadly, I have on several occasions forgotten to tighten cutters held in my quill mounted tool holders :( However, I don''t think using this new fixture will make me any more vulnerable to such lapses - hope not anyway :) Cheers.

Thanks Carl. I rounded the end using a clamping accessory I made for my bandsaw, and removing material with two angled cuts on each corner. This left small amounts which were easy to remove on the belt sander. I didn't show this because the video was already over thirty minutes long and this seems to be the limit that many viewers prefer. Cheers.

That's very kind of you to say and I'm glad you enjoy my videos. Cheers, Alan.

That's a good point - I catch my hand often enough on the tool in the quill while futzing around under it. Cheers.

The Vertex boring head is a very nice bit of kit. It'll consistently remove 0.01mm off a diameter and can be finessed to ~.005 - provided the operator doesn't lose count of the clicks :) Cheers.

Thank you

Thank you.

Thank you. The design was influenced (as usual) by what was in the scrap bin. My first idea had been to use a short piece of 100mm square tube and just bore a big hole in the top and a small hole in the bottom. However, I didn't have a suitable piece of stock, and a socket with matching taper does locate the adapter very positively. The design also allowed me to round the piece off and avoid nasty corners. Cheers.

Thank you.

Yes, that "honey mustard" is nasty stuff and provides no anti-corrosion protection - it will be replaced asap. Thanks for your feedback Stewart.

@@alanshomeworkshop No need to replace, I just thought it was funny, that's all, love your content

Thanks Henry.

Thanks Ralfy.

Thank you. I share your interest in repair and reuse of things and materials. Cheers, Alan.

Thanks Allen. It's very satisfying to get a silk purse out of a sow's ear :) Cheers, Alan.

Thanks Graedon. My lathe tools cope well with it, presumably because of the constant engagement pressure. But my milling cutters are on the struggle bus - to quote another CZcamsr :)

Thank you.

Thanks - and good to hear from you again. I'm a bit tempted to test the Loctite adhesion to breaking point just to see if it measures up - but I'm not sure how I could measure the yield stress. The hardened layer on the 60mm bar was actually 3mm thick but it did cut cleanly, albeit with a very loud squeal. What feed rate do you use when stripping it off ? Cheers.

Thanks for the feedback Mike. You are right about the depth of cut - but I did actually correct myself at 15:00 Cheers, Alan.

Sorry Alan. I didn’t get that far in the video as I had to go out. Looking forward to watching the last part. Cheers 👍👍 Mike

Thanks for your feedback Bill. When I started working on cars as a teenager in the early 1970's, Unified threads were the norm in locally (Australian) manufactured cars but Whitworth threads were still common in plumbing and general hardware products. Metric threads were common in imported vehicles and starting to became more common in other domains. So I have worked with all three systems and have a good coverage of taps and dies for them. I have also worked with other metric thread systems eg BA, and pre-ISO JIS (they are found in pre-1967 Japanese cars and motorcycles). When no other factors apply, my preference is to work with ISO metric threads especially when using my lathe as it has a metric lead screw. But I also have quite a large range of imperial socket head screws (an auction purchase years ago) and prefer to use them rather than buying new metric items. Cheers, Alan.

There was a bit of head scratching and high school trigonometry :) End result was very pleasing though and I have found the cutter to be a useful addition to my toolkit. Thanks for watching John. Cheers.

Thank you

@@alanshomeworkshop gracias

Thanks Graedon. I'm certainly getting plenty of practice at fixing mistakes :)

Thanks Kit.

Thank you.

Good'ay Paul. There's a steel supply store near me and they have an offcuts "bin" for pieces under a meter. I cruise through from time to time and check it out. My good mate Murphy ensures that I'll never find a good offcut when I need it, so I go looking when I don't :) Thanks for watching.

@@alanshomeworkshop Murphy's always hanging about somewhere, sticking his oar in😁

@@paulrayner4514 Are you familiar with some corollaries to Murphy's Law that are particularly relevant in the workshop ? A dropped object will always land where it can cause the most trouble Where there's a possibility of multiple failures, the most damaging will occur The probability of the loss or breakage of any part is directly proportional to the difficulty of getting a replacement part. Material will be damaged in direct proportion to its value. And one of my favorite aphorisms: - And a voice from the gloom said smile for things could be worse; so I smiled and, yes, things indeed became worse.

@@alanshomeworkshop oh yes, Mr Murphy is quite prolific in my workshop, I'm beginning to wonder if he's using my workshop to train his offspring in the mystical art lately.😁

Thanks Henry.

Thank you.

My I-Beam is 6"" deep by 3" wide with tapered flanges (the modern Universal Beam or UB profile has parallel flanges). This was the minimum width recommended for the trolley. If it is fitted to a narrower beam, the wheel flanges cannot be set close enough together to track correctly. I did mount the trolley to the beam first and then bolted the hoist up to it: czcams.com/video/KJXbOYrOMxI/video.html Thanks for comment and I hope the video helps you achieve your project. Cheers, Alan.

Thanks Paul. I've tried a few different magnification options with varying degrees of success. I currently use a USB microscope (eg for the valve stem photo), and a headband magnifier with 5 lenses for work in the lathe. The microscope is ok and more useful after I made a taller column for it. This is my "go to" tool for metal splinter removal. The headband magnifier was ok but the lens retaining clip is cracked and the lenses are prone to falling out. It also requires me to get up close and personal with the target - not always desirable with the lathe. But I shouldn't keep whining about it, there are people much worse off than me :) Cheers.

​@@alanshomeworkshop Somewhere, a mobile phone was used as a magnifier. Not sure, me I do not own one, and never will.😊

@@alanshomeworkshop I know what you mean with the head bands, i've got 4 of them. what appeals to me is I've see Joe pie using a loop and he puts the loop close to the work with his head away. like a normal magnifying glass I suppose.
