Re: For those with machining experience. Sleeve fitting??
Way back in my school days, learning experience only, I bored several Briggs & Strat. lawnmower engines they were junk anyways. Did this on a mill with a boring head. All
went well cause my father has all the toys; like bore gauge,snap gauges, mics and most
of all the "black book". get this book off Ebay, you won't be sorry, they are cheap because
a person can not keep all this math in his / her head before 'meltdown': fast forward 50
yrs still doing this and still on the same mill 4cyl Model T and A's or any inline a snap.
Its the V8s of any make. So I Have to come up with a complicated jig (not yet) for V8
set up on the mill by that time I'd be 110yrs old. So a shop, a mile down the street 'we
work together'. I brought him a 59A with number 6 cyl. somebody went there with a die grinder the cyl wall looks like asphalt parking lot. I told them my plan. HERE is where the machinist hand book comes in. The 59A is 3 3/16 std bore, That, we know, next we
bored that to clean up measure & look in the book for sleeve size OD. Sleeves come in
various OD's and ID's. May have to tweek the bore for sleeve fitting with boring head,
after thats done and was measured & sleeve removed from the freezer and banged in, If
you got things right, a little tapping with 2lb hammer it will get to the bottom lip. Ain't
going to just fall in a little meat with the hammer when the cold & block temp equalize
thats staying Now mill off the top of the sleeve. Now with bore gauge measure all
cylinders write all down (includes ) tapers etc. Then come up with a number; example we will bore all 8 at .030 which means WE have one correct bore , thats the sleeve, and the rest 7 are worn with tapers ridges etc. So back to your question you need to measure + then plant the tree the (sleeve) I don't care what this new world says about
the final hone fitting ==BRING the new pistons. And the cost, that depends where you Live in or near Las Vegas common sense thats deep pockets there. Here east coast just
tire kickers. Bottom line this shop thermo cleaned, polished crank, bored and sleeved,
resized rods back to standard. We did all valves & assembly = their bill $435. My bill, I
didn't get my hands dirty. so don't listen to all these 'oh flatheads are expensive to build and thats BS
