Thanks

What I've got is a chevrolet turbo 350 converter, with three mounting points equally spaced. Three and six are easy. Draw your circle with a compass then without changing the compass step off marks around the circle. The chord length on a circle with 6 divisions is equal to the radius. For three bo...

C = chord length (9 in your example) D = diameter of bolt circle D = C/sin(60) = 1.1547 * C = 10.392 for your example You need to divide by sin(60)=0.866.. rather than multiply. This is where my math is weak, I'll use this formula. scmods Difficult for me to lay out with a straight edge and a right...

I'm a hobbyist and a hundred years away from geometry class. I've come up with a formula for finding a bolt circle dia. out of the machinist hand book 23rd edition. Pg. 75 "lengths of cords for spacing off circumference of circles with a dia. =1." What I've got is a chevrolet turbo 350 converter, wi...

Thank you Bill
I was wondering how big/small to make that chamfer.
I hit a real snag, and tore the block back down.
I found grit in two lifter bores,I guess my two cleanings weren't good enough.
So while its down I'll get the die grinder out.
Thanks for the help guys

LOL you guys are funny, I'm a hobby guy. To build the tool with out a mill would be tough. At my age I might not get the car put back together. But my ridge breaker could be modified to behave like a valve seat cutter, I think. How ever I'm headed to NAPA for lint free rags and tape. Think I'll try ...

Tell me the bore diameter. There are tools for that. They affix to the ... well, tell us the bore. They act like a valve seat refaceing tool. It started out as 4.00" Now 4.030" , the old pistons wouldn't do. I would like to see the tool made to bevel large holes, wouldn't buy one for a one time use...

I wouldn't recommend that engine builder to anyone. How can you forget to do something like chamfering those cylinder bores. Stuart I wont be passing out his cards. I have one tip that doesn't swivel, it's worked the best. This is for my hot rod, don't mind taking the time to do it by hand. I do ha...

I did buy a new tapered ring compressor,
thats why I was suprised to see the oil ring wouldn't
go in.
Thanks guys

I had my machinist deck and bore an engine block, he forgot to chamfer the top. The rings wont go in with out it. He told me he uses a hand held edge breaker. Deburing tool with the tips that swivel. Which I have. The guy who is guiding through this rebuild, said to turn the engine upside down, on t...
