It must be very difficult for people like yourself living out in the 'stix'. I just order something one day, it is here next morning.

But if you look at the other side of things, you will learn a lot more because you have to make most of the stuff yourself.

I used to make all my own tooling and bits at one time, and even now, when I see a bit of scrap, all I can see is what it can be used for or what can it be made into.

Thank you for understanding John  :bow: , and yes, I came to the same conclusion regarding the learning.  Anyway, the satisfaction I get out of making things is priceless.

Kind Regards, Arnold

John,

You are quite right, but most of the time, it is short pieces that are being made.

But there is nothing stopping you making one for the other end of the spindle, and working from that. Some sort of taper locking and a large faced end going forwards. In fact, if yours is the same as mine, it has screw threads in the back end of the spindle, that are I think, something to do with gunsmithing and boring barrels. I am looking to put them to use sometime for a turning handle and long bar precision support.

  Thanks John, I have an mt taper from my failed homemade collet project ( to much runout on collets) that I can use.

  Thinking this could be used to make the top end support rods for your Paddleducks engine the same lenght.

Ron,

That is exactly the sort of jobs it is used for.

I use a backstop in my 5C collets all the time, but as I have explained before, they are not super accurate because the position can be altered by how much you tighten the collet. This type is spot on, because once it is locked into the spindle, it is going nowhere, and once your saddle is locked, you can just face up to the same length time and again.

 Thanks John, Good to know.
