I have started one of those ages ago. I have yet to get some silver steel for the punch.
I guess I'd better finish it while I can still find my way to the lathe.

One of my hacksaws is very similar to the third one down on the right of this picture. It originally belonged to my Granddad so its getting on a bit. The blade is quite a bit wider than the blades around nowadays. My normal use saw is a "Bacho" with a plastic coated frame.
Although I was taught to use a saw properly I do tend to be lazy and use my chop saw particularly if I want an accurate cut...Best Regards:

Hi Grahame,
are you going to turn the shank of the lucite down at all and leave a larger head?
If so, then you may need a smaller diameter piece of silver steel. I found I didn't need such a large head on the punch but the bigger head on the magnifier worked well.

My apologies Phil ,I completely forgot about PM -ing you.
I had not considered it, but now will as it obviously works. Its been that long it getting a roun- to- it.The lucite has sat on the desk near the computer for 18 months.
Thank you for the pics - explains it all in a glance.
I suppose I have had the mind set of the shaft being the same as the lucite-.
The original diameter of your lucite- was it around 12-13mm >.That would make the silver steel shaft half of that. I understand that this is just to "pop" the mark observed and centered by the optical bit.
Some of course not be able to separate "pop" from wallop.
Thanks
Grahame

No worries Grahame, at least I'm not the only one that forgets.
Mine is 3/4" oops, about 19mm and if I remember correctly the shank is about 10 mm so the ratios you mention are about right.
I use the smallest ball pein I have and as you say, it is just a 'pop', and 'then' you centre punch it.
