How to cut tubing to bush an oversized pivot

[pinklather]

I don't know if the std. plumber's tubing cutter is too big or if the tension required to us is more than a grip on the tubing can successfully rotate. How are you guys cutting your tubing? Keeping it from collapsing, etc?

I have always used the regular dremel cutting disc. I am sure you will get some ideas from the members.

I will roll it back and forth under a single edge utility razor blade till it cuts, or use a jewelers saw.

+1 on this; I then use a jeweler's file to bring it down to exact fit.

Lots of ways to do it,this is what works for me.I bore out the usually oblong pivot hole with a carbide burr that is exactally 1/8 in. dia.,tap in a pce of 1/8 in. tubing.Cut it almost flush with maybe 1/64 overhang on each side,I use a very fine jewelers saw also.,Than using an oversize carbide burr, I create a conical shape on each end of the tube.
Using my pinning hammer,I than peen it down to fill the usually dished sides, works for me,

Here is how I do it. my method is quickest using a disc sander.

I also prefer to use a jeweler's saw, and then file it to the exact width.

In all of the restorations I have done it is rare to find a pivot hole in a razor that would be considered 'sized correctly' and if we were to take apart razors we consider functioning properly I would expect that many, if not all of them have over sized pivot holes. If the size of the hole were an issue I believe that this 'issue' would have been address by the manufacturer's long before we got our hands on these razors. Put bushing in the holes if you like but I do not see any earned value for the effort other than to satisfy the restorer that all 'issues' were addressed. My take is "If it's not broke, don't fix it". the fact that a razor is being restored usually means that something was broke but I would venture a guess that the pivot hole was not the cause due to the fact that most razors have pivot holes in the same condition and they are functioning properly. The question now is "Does reducing the size of the pivot hole cause any future problems?". I don't know but having the blade float in the scales may aide in it's function.
