Bump straight knurling tool

After making a scissor knurling tool, I become intersted in making a straight knurling tool since it:

> is greath when you need transmit torque between a steel shaft and a plastic wheel.;
> it can bring me more choices when making stuff;
> I can "save" a interference mount part infortunatelly made too loose.

I took a 1/2" square and milled the wheel slot

Turned the 1/4" pin from a 1045 bar. Here you can see there a section slighty bigger for interference fit

Pin was heated red hot and quenched in water.

After welding the side tab and cross drilling the 1/4" hole, I pressed the pin

Test run. I've made a fine (0,8mm) and a coarse (1,25mm) wheel.

Hi Cascao, nice work as usual,
For what its worth I have found that straight knurl wheels will work just as well in your scissor tool.
I have diamond knurls but prefer the straight ones and they have been mounted in my old scissor tool in the rear toolpost for years.
I agree with your observations on their usfulness.

Olderan, didn't really know that straight knurl wheels can be used on scissor tools, nice to know. I belive (and hope) that since only one is needed, (the pressure on bearings is smaller) it is less harmfull to spindle bearings.
