i need a hole tapping!

Post by pyro » 10 Feb 2011 05:45 pm

HI guys and gals, Ive been trying to get a thread insert (not volvo related!) retapped to a suitable size, ive been round the machine shops in selby and the college were i spent alot of years and no one seems to have anything the right size,

Im looking to get a 3/4x16tpi hole, re drilled and tapped to 1" bsf (10tpi)

can anyone help on here? I cant afford to buy a set of taps that ill only use once!I know a few people on here have a good source of engineering bits so if they could help out id be very grateful!

its the internal thread on this collar here,

thanks!

Ben

£8 in carbon from Tracey bud!

Might be the cheapest way. If its's a through hole you'll get away with just the taper ;)

aye id looked at tracey tools, the hole is indeed through but 40mm deep/thick.

being a tight fisted yorkshire man im loathed to spend money ive not got on a tap ill use once!

do you know anyything about the strength of duel threads - ie lh and rh in the same thread? some people use them on their lathes, just doesnt seem a good idea to me!

Fraid I don't bud... but there is a lot of meat in a 10tpi. What is the application?

I was waiting for a VND reply! :mrgreen:

its part of my new lathe, its a spindle thread adaptor.

external (m33x3.5) goes into the chuck.
the internal thread, currently 3/4x16tpi, needs to be 1" bsf to match the spindle thread on the lathe.

Makes sense, the headstock spindle on my metal lathe is 1" BSP too, hence why I know the price. Not bought one yet though, but I need to do a faceplate for my 4-jaw.

Not something you want to come flying off then ;)

I meant BSF.... silly standards.

All things useful in life can be dealt with in either metric, or Whitworth. Mine is an early one of these http://lathes.co.uk/ideal/ infact, the first picture pretty much sums it up. Old skool awesomes
