I like the open ended terminology. "medium hammer fit".

That means I got it a little tighter than I intended and had to finish with a hammer. If it had been a tight hammer fit I probably would have tried to get it back out, if not bored it back out and started over.

I've been using propane to get parts a little smaller to fit tight spaces. Bought one of those do-dads where you turn your 20 pounder upside down and refill your little torch tanks. It didn't work for that, but if you use it backwards, screw it on an upside down torch tank, it shoots liquid propane out in a healthy flow, and chills down parts nicely to where the will drop in instead of a press fit. Propane boils at -40deg, pretty cold, and beats the freezer. Did a sweet job on a shovel valve seat.
I suppose if you took the orifice out of a regular propane torch, you could do the same thing. Never tried it though.

Did you not have concerns .0075 would be a bit to tight and crack the case again ?

Then I discovered that the pinion race bore is well machined just to an odd size that isn't available now if it ever was. So I started making a pinion race with a .0075 oversize OD.
This drill bit in rockwell 45 shaft is all the little Atlas Craftsman wanted even in back gear.

The case measured .0075 over standard so I made the race .009 over a thousandth and a half sounded about right If I ever make another I'll probably back off to a thousandth negative. The rocker arm pivot bores and the cam bearing bores all look to be different sizes haven't measured real close haven't decided whether to to bore them to a standard os or make to fit parts yet. I'll fix the mating surface first.

The wife passed last week so I'm trying to keep my head up and find thigs to keep busy so I'm back at it.
With all that welding this is the straightest case half out of this lot. .002 to cleanup after the weld was smoothed .110.

Got lucky on fleebay didn't really need this case half but for $49.00 I'll fix it just in case (Bad Pun)

Started making rocker arm shaft bushings seemed easier to make bushings to fit than to set the cases up in the mill and bore to a standard oversize.

First one parted off.

Ready to push in.

Will start making the shafts in a day or three. Making them out of Rockwell C75 pins so will have to be ground.

Since I'm a firm believer in not sandblasting cases and these needed cleaning.
Image
I gave em a little soak in warm Pinesol.
Image
then ran em in the dishwasher.

Got a few goodies today.

Please tell us more about this cleaning procedure. Is there a special mix ratio ? A time limit ?A particular vessel material ?

Just pure Pine Sol The generic knockoffs don't work at all they don't have the right kind of acid. Any kind of pan seems to work, Don't heat it too hot I try to keep it just as hot as I can stand to put my hands in. The occasional wipe with a stainless pot scrubber hurrys things along. When I'm pretty sure it's clean enough I run it through the dishwasher. When the Pine Sol in the pan is cool I dip off the nasty stuff at the top then strain it through a rag back into the bottle for next time. As long as you don't boil it and strain the oil out it works again and again.

OBTW

Don't decide that putting pine sol in the dishwasher might be a good shortcut It'll fill the kitchen knee deep in suds!
