Modifying a tool

When trying to make the headlight lens for the RS 1, which is 1/4 inch in diameter, I found that the leather punch I was going to use put a big dent into the clear plastic as it had a sharp point on the male member.  So, I figured I could make a brass collar to surround the point and make the head of the punch appear flat. Using brass rod, I turned it to the required diameter, then drilled the center out to allow for the point. The whole assembly is here.

Then I glued to adapter to the punch using canopy glue so it would be easily removed, should I need the punch to be usable for heavier material. The punch is resting on the female member of the tool. 

 Here, you can see the punch point in the interior of the spacer. When I used it, it worked perfectly but the glue could not hold the spacer when the punch was withdrawn from the material. Not a problem as it was easily re-secured, and a second lens made.
