Title: Cutting Big Holes In Thin Sheet
Post by: doubleboost on September 11, 2012, 04:56:57 PM
Hi
Lads
I have been wanting to make a storage rack for R8 collets for some time
I had thought about using wood (but i just dont like the stuff)
Settled in some 1.4 mm aluminium
This was cut to size and bent to fit in a metal drawer
Marked out to give 30 holes
I made a simple hole cutter from some shiney bits of steel i had found under the bench
The pictures tell the story
The studding is 10mm the finished holes 23mm

Finished job much better than those red plastic tubes

Nice job and well executed..... :bow:

Looks simialr to the Qmax chassis punches that were around in the 70's.. ( I think they are still available? )

It looks like those holes came out nice and cleanly.  I wouldn't have realized that you could get such nice results with that method.

Yes John, still around. Bought a 5/8" about a year ago. I have about 12 of them. No soddin' 5/8" size though.
How is it you seem to have every size except the one you need ...
I felt sure I should have one. IIRC it was for B7G valve bases ...

Tidy work there John... that die - did you cut it on the lathe with an interrupted cut, or on the mill with a large cutter, or some other method?

Thanks for showing  :thumbup:

Hi
Ade
I turned the die to be a good fit in the sleve then just put it in the vice and milled the end with a big cutter
A bit dress up with a file
