I get 90 degrees now.
No squish band. The object of the exercise is to get this thing to the point where it will run and then make a decision on a frame. If it comes to fruition, and like what I end up with, then I'll see about spending some of the children's inheritance on a head, barrel, piston etc. Probably not the best way to go about it, but a quicker path (for me) to getting it running. The head, barrel, and piston I'm using were already on the shelf so if it ends up to be something that I won't use that much, it hasn't cost me a pile of money.
The cylinder turned out ok. The bore gauge reads .0065" clearance and appears to be straight. A .006" feeler gauge slips in with a bit of drag. Seems strange to me when used to working on stuff that goes in the dumpster at .004" Finished it with 280 stones which Hasting says are ok for cast rings. I may go back a give it a few revolutions with a 220 flex hone.
Anyone have a photo of the jig they use to hold a head in the lathe? I could get away with glass and emery with this one, but a jig will come in handy down the road. I think I have a plan, but seeing one might save me some time.
