Looking real good Stew.

I like your split collar method of attaching the flywheel. But the upside down boring bar makes my stomach a bit queezy. :lol:

And a Merry Christmas to your too.

Hey Ralph, you ever going to finish your Aeolipile? (sp?) :D Ya, I know :offtopic:

That's excellent Stew. I like that method of fastening a flywheel. in fact I was going to try it on my engine last night with a lighter flywheel. Engine is looking great.

Merry Christmas to all.

Happy new year Chaps

I bet you thought I'd given up on this. Spent new year St Ives a Cornish fishing village/town, made a complete fool of myself by joining in the fancy dress party that the town holds, got a little bit tipsy dressed as a red indian (must have been the fire water).

Any way on with the build:- con rods.

First job draw the rods out in cad and dimension the key features from the centre line of the big end bearing, then cut some plate to size, for the rods important to get all the bits the same size as it will help help in doing all three with the same set up.

Then set up in the mill bringing the vice stop into play then drill big end zero the DRO in X and Y and then drill other holes, repeat, repeat.

Her we have them all drilled.

Put a couple of same size rods through the web holes sit them on to a couple of parallels, tighten up the vice remove rods and parallels.
and chew out the meat.

Fit the big ends with 1/4" phosphor bronze bushes, the little ends are also drilled 1/4" (that I will bush later) and make a 1/4" mandrel, one mandrel will do both ends.

Then fix on mandrel and thin the webs.

Flip over and locate on the other end and thin the other side.

Then with the mandrel held in a collet on the rotary table round the ends off.

There we are done they just need a tickle with a file to tidy up.

The centre con rod is at the back in this pic with the two off set rods in the fore ground.

Have fun

Stew
