Spindle pin bore

[Lawrie]

My 34 needed a few small jobs after its trip to the nationals (5600 klms)
One was a loose king ( spindle pin) pin on the left side|
This was the same as the problem that was on the right side before the trip.
It looks like the pin had been built up with some sort of spray material like a Utectic torch job, but I could peel it off with a screw driver.
The bore in the axle was .825 in ,should be .812.
The bore was nice and round and no taper, so my fix was to turn up a small sleeve for the bore and loctite it in.I used an old ford axle as the bar stock and turned up the sleeve .825 od and .812 Id , this is a fiddley job on the lathe ,but came out very nice.
Fitted two new bushes and reamed them to suit, one thing I found is the smallest of nicks or marks on the pin will cause it not to fit the bush nice, the temptation is to take another cut with the reamer, it took a few minutes with a fine oil stone to remove them ,mind you, it’s a bit much to not have any as these came from the original ford packet.
It’s all back together now with a NOS ford pin fitted,

to get a smooth final fit on a job like this would be to use "time savor" product.
its like valve lapping compound, but less aggressive, and does not leave any residue to keep grinding bits when done

Well done. Great to have a really good lathe like yours.

Nice fix,Lawrie. You can tell a guy's run a lathe before when he uses a four jaw chuck.

When you want it right on the gnat's ***! Perfect

Yeah, the guys I'm jealous of are the ones that have a super-quality lathe that is totally accurate with a 3-jaw chuck. I only wish I was "that guy"! LOL

I just purchased a used 8" 3-jaw for my lathe - have to do some creative "tuning" of the jaws to get it a lot closer to spot on. Too much run-out at the moment - even with a newly made back-plate (made on this lathe for that chuck). Argggggh!
