Hi All,
Now that I have been shown how to do it I should be able to show you a few pics of my build.
The flywheel was made from a lump of 1" thick ali plate that had been donated to me a couple of months back, just waiting for a job like this.
The bearing blocks I made from cast iron, I find it is a much better bearing surface for brass rather than the steel that was on the plan. The cast iron came from old window sash weights, I find I can get about 12" of 11/2" diameter bar from one weight for a cost of 30 pence (about 50 cents US). I decided to use ali plate for the flywheel upright as well so this has a duplicate cast iron bearing bolted to it and upright location dimensions changed slightly.
You have most probably gathered by now that I don't use much full price material, most of mine comes from scrapyards and friends and I throw no raw materials away until it can be of no further use. This engine will cost less than £4 ($8 US) to make, and most of that was to buy the silver steel (drill rod)
