Piston Machining Part 1

First video in the series of machining a rough casting to a finished piston for the 8HP Mogul engine restoration.

Very nice and interesting project. Found your channel by accident. Just subscribed to your channel. Take care, Ed.

[@round2itrestorations855]

Thanks Ed subscribed to yours too

Good Job. Keep up the good work

[@robertoswalt319]

Interesting video. I look forward to watching the entire series.

Great video!

[@round2itrestorations855]

Thanks!

I wanted to see how you cleaned up the rough casting to chuck it initially.

[@paul.newland]

You have to chuck it on the rough casting initially so there’s no clean-up. That’s why a 4 jaw is used, so it can be centred true, at least as best as possible since the casting isn’t likely to be perfectly round. Then you lightly face and skim a registration diameter on the other end so you can then flip it around and work from there. He’s done exactly what I’d do, except I’d always do the face first so I can use a centre in that face to prevent the following diameter cut pushing the work off-centre. 🇬🇧

Nice casting. Just a thought. You could have dialed in the inside of the piston casting to get concentric instead of the outside.

[@round2itrestorations855]

Agreed this was the best way I felt for the tooling I had many ways to do operations

[@jgoverton13]

Really love the content . I would encourage you to work on the technical aspects of your presentation ( lighting, audio) to help your channel grow. Thanks for making this available.

[@round2itrestorations855]

Yes I agree trying to improve a bit at a time for me the problem is where the camera should be is where I need to be😀

[@andrewdalgarno5322]

If there's enough length in the casting, I probably would have got it dialed in as close as possible and then drilled a center in the end so the tailstock could help support it. And then in the final operation, when machining the angled faces, the center hole could be faced off. Looking forward to the vids. I'm working on an 8hp Gilson (approx 1910-1912 era) at the moment.

Dang that's a bigun.

[@round2itrestorations855]

Yes I think the finished weight will be around 33 pounds

The Chuck drive looks like it’s rotating opposite direction of Chuck mounting assembly. Optical illusion or planetary drive assembly behind Chuck? I’m not a machinist just a novice wannabe.

[@round2itrestorations855]

Yes just an illusion lathe speed was 94 rpm

Hi, I was interested to watch your video but unfortunately the volume of the audio is very inconsistent, could barley hear you.

[@MegaDirtyberty]

Agreed, and he talked alot.

[@round2itrestorations855]

Working on my video quality it is a work in progress

[@MegaDirtyberty]

@@round2itrestorations855 It is hard making videos, editing is even worse (I have found). I try to do a short introduction and get into it, then explain what I am doing as I am doing. :)
