Upright machining?

Silly you? silly me..
Yes 19mm and yes makes a good fit

Yup.
Seemed to be perfek.
Hard to beleive for £3.85,
especialy as some people want 20 quid for the mod

so when reamed, the OD of the lower hole should be at 16mm.

Cool.

See, now you getting complicated.

When I did mine I kept doing a bit then tested it, till I got about half the thread through.
So when I tightened it up it pulled in snug without the thread bottoming out.

Not sure, but think if you did it till the bottom was 16mm it may be too much.
You will need someone that has done one recently to be sure.

i did mine as Dogwood suggests,

a little at a time, keep checking that you haven,t gone too far,

takes about 10 mins per upright, do it like tapping a thread, half turn in quarter turn back.... keeps the cutting edge of the reamer clean of swarf & helps get a clean cut on the steel.

Sounds easy enough, I just remember when I started a Locost back in 2004 that this was one of the difficult bits to get done ( or there was no information ). Which is why I bought Astra bottom ball joints.

I gave up that build due to a number of issues and sold the chassi.. I got an email last year from the guy that bougt the bits saying he needed a quick letter to state the chassis was new as he was about to register the car

thats funny andy if you look at this quote of yours back in august you said it took you 15mins a side

whilst turning the reamer just keep downwards pressure on it so that it is actually cutting.

thats a sign of working too many long hours, you loose all perspective of time
