Potty Popcorn Engine
sbwhart:
Thanks for your comments and interest Jack.
And thanks you're boring bar tip I guess the lead adds weight and deadens the vibration.
I can remember visiting one of our subcontractors, one job he had on the go were large hydraulic cylinders about 6 ft long with an ID of about 9" he had it mounted on a large long lathe with fixed steadies, and was using a long boring bar that overhung the back of the tool post by a significant amount and he had a big three jaw chuck fastened on the end of it, I asked him about the set up and he said it was to counteract the bend and natural vibration frequency in the bar.
As for putting her on steam, I don't have a boiler for that, I guess I'll have to build one someday.

Hi Stew, I`ve not been keeping on track with this and just caught up. Amazing work as always!

Finished of the supports.
I stuck the two supports together with two way tape, and made a couple of plugs to go in the holes to stop things moving around, I also made a filing button, for the top eye.
It was then a matter of nibbling material away from where its wasn't wanted.
In the mill
And with files.
And used a slitting saw to cut through the base, and cleaned across the base with a fly cutter, I'd plugged the bearing hole together, so the crank shaft will sit perfectly level.
A bit more work with files and they are looking something near, I'll tidy them up a bit more but has they are going to be painted they won't need polishing.

Stew, could you explain how to use a button to file a round? It is apparently a simple process but I`ve not tried it yet. I think you showed it me in passing a year or so again when I visited but it was in passing and taking everything else onboard, I`ve forgot! :doh:
