Finally my V Twin hoglet runs

neil_1821 · May 13, 2018

Im still far from finished, I’m currently making a box for it to mount on and hide the electronics but my V twin finally runs! I’m still setting up the mixture and the idle stop but I can’t contain my joy. This has been the first IC model I’ve ever made and I’ve had countless problems which has resulted in many remade parts, camshaft, about 6 pistons and a few connecting rods!

Nice Job, Randy would be proud of you.

If you have issue # 34, there is a good article on making a nice box base by Dwight Giles.

When you get it done, send me a picture for Reader's Engines.

Very nice. What kind of problems did you have with the camshaft and pistons? Only asking incase I run into the same problems when mine nears completion. Did you use viton o rings on the pistons or make rings?

The first camshaft that was made, the lobes were about 10 degrees out so couldn’t get the timing correct. Still not sure how it happened but we used an off center cutter in the milling machine and a rotary table. Second time round I used camcalc and cut a new one mounted horizontally, which was more accurate and quicker. The other method would be to turn the lobe profiles, cross drill and silver solder them in place on a blank shaft.

Yes I did use viton O rings for the piston rings but I was amazed at how tight a fit they need to be in order to prevent loss of compression, they do bed in with running though. I think I made 6/7 pistons due to them leaking. I learnt a lot being my first IC engine so hopefully any future projects I shouldn’t have the same problems. Be sure to post yours when it’s done [emoji846]
