Milling Machines
Hi All - I hope im putting this in the right section. I want 60th machining off my pinto cylinder head and ive been quoted 150 + vat they say it is
this price because its equiv. to 6 cylinder head machines. That works at 10th a head is all a milling machine can remove at once or are they ripping
me off by saying they can only take 10th off at one time? Thanks for any replys Jacko

Ripping you off, take it to Bradford Grinders.

The time is taken up by clocking the block in place, so it is dead level before making a pass. This may take upto 20 minutes if the block does not
have a parallel base, 10 mins if it does. Each pass takes about 2 minutes, a set of tips costs about £60 and you would probably get about 100 passes
out of a set.
Work it out!!
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

maybe I'm reading it wrong, but isnt a 10th 6 times more than a 60th?
6 passes at a 10th each time will be 6/10ths.
or am I wrong?

I think he wants 6/10 milled off and the milling machine will only take 1/10 per pass.

I think
he means thousandths.  If he took 6/10" off there'd be valve marks on the bottom of the sump  . Take it off with the angle grinder and
ask them to just finish it off for you 
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

That's why i said i think
I did not put the inch mark behind the figure Peteff,you did.
I was talking about 1/10 of a millimeter hence the absence of the international sign for inch (" .
I did not realize that with six tenth of a millimeter removed the valves would make marks on the bottom of the sump.
I'm learning every day.

I just realised that I read it wrong, it is the head that is being skimmed. I am sure that 60 thou is the removed dimension, which is 1.54mm - now
that should only cost £20. The pinto head is a parallel head, can be lifted onto the deck by hand, and the protection required is minimal - yep, you
are being ripped off - big time

Alright Gilbert...
I was exaggerating a bit. If he'd asked for an estimate to take 0.060" off we'd have known what he wanted. I think we're all
agreed he's being ripped off though. edit:- three years ago we had a pinto head skimmed 0.90", new seats cut and bronze guides fitted for
£80+vat. at John Noble motorsport.

A 60 thou skim is 2 passes, 50 + 10, even £50 is a shaft

RIP. OFF! I can only assume they can't be arsed to do the job, hence the high price.
