Making 5C Collet Block Nuts

[terry_g]

The collet block set I ordered the nut was too big to fit in the bore of my 3 jaw chuck. Making a smaller one was the next project.

The 5C collets have an odd sized thread 1.238" x 20 the nuts that came with the collet set measured 1.180" ID. So I turned a piece
that would fit the chuck bore with an ID of 1.180" and single pointed 20 threads per inch in it. I made the part long enough to make
several nuts.

Next I made two cuts with the metal saw. I clamp them in a length of angle iron with a previous cut in it for the saw blade. I think I cut more on the opposite side of the blade than I do in the vice.

Canadian Tire had G96 cold bluing on sale for half price a couple months ago so I bought all four that they had. Its one of the better cold bluing's that I have used.

The end result. The block now butts up against the chuck so its gripped more securely. It probably did not matter as most of the work done in a
collet block is going to be small diameter and light cuts. It was just my OCD kicking in again.

What is the bore of your lathe? Could you use a drawbar instead of the nut? Easier to use, since you don’t have to remove the block to change collets.

Love the angle iron idea.
Very nice work.

Link? I found one for Birchwood. Is that the one?

They might not have the G96 brand right now. I have never used the Birchwood brand.

My spindle bore is 1 7/16". A drawbar would be simple to make.

I made the wrench for the collet nuts. An old bolt and some mystery metal. Does the job.

I love making stuff out of the scrap pile. Fortunately I have been able to access a pretty good scrap pile from time to time. Might be time to swing by and see if I am worthy of another shopping spree. Got a bunch of hydraulic pumps, valves and motors on my last spree.

I noticed a big plastic bin at the front door of a tool and die maker. I keep thinking maybe it's a drop box for cutoffs..... I need to take a look someday and maybe go in for a quick visit.

Careful. May be a trap...
