Hello All,

I sort of painful job with these guys is making all those cylinder and engine parts. So I tried something a bit different to try and get nice circular cross sections and to make parts a bit quicker...

I cut out the strips that would be part of a cylinder, measured their lengths with calipers since this would be the circumference. Knowing that Pie x D = Circumference..I just divided the circumference by Pie and got a diameter of the cylinder. I then took calipers and measured the thickness of my paper and subtracted 2X the thickness from the calculated diameter leaving me with how thick a filler cylinder would need to be for my engine pieces to roll around. That piece was just rolled with some typing paper into a long tube.

Then I glued each of the cylinder pieces to this interior filler (I pre-formed a little curve into each), let them dry, "painted" the strips (on the inside) with a bit of water to help them curve and glued them around the filler as shown.

After drying, I just sawed them off like sausages. Pretty slick.

Then the crank case was made and the parts slowly added.

Next are the cylinder tops and push-rods. Then she'll be done! Neat engine so far.

Cheers,

Dan
