LETTER PUNCH GUIDE : aim the line and write everything straight! Punzonatura

https://www.youtube.com/watch?v=HB1lUYkLFfI

Good morning everyone,

I show you my latest video: I built a simple jig for punching flat and round parts, in the now more or less advanced laser era I built something "old-style" which is based on a "needle viewfinder" and a metric row to decide the step between one letter/number and another;
a second viewfinder allows you to align the plate in the case of punching on a larger detail, with a hypothetical pre-traced line to align the letters/numbers, in this case it requires 2 external clamps for fixing.

The cursor also slides if the plate is pressed on the part to be punched, because it is slightly less thick in the guide area.
On the base of the support there is a plate which, when rotated 180 degrees, has a 45-degree V-shaped machining, to allow even round bars to be blocked and punched.

It's always a challenge until the final assembly and the test, because if it doesn't work it was all done for nothing, but on the other hand this is part of the game and a game that I'm very passionate about!!

Hope you like it,

Ciao !!
Alberto.

Nice build. :thumbsup:

That is probably the best idea I have seen for laying out stamps. I have a couple of rifle builds that need info on them. This will be a great thing to speed things up.

Hi Mr Milkey, thanks for your kind comment, happy that you liked my video !!

Hi blkadder, happy and proud that you liked my idea !! The first idea come from the serial number wrote in the past on the lathes or milling machine, for me seeing the date of construction has always fascinated me because the piece of iron immediately acquires a story, obviously unknown but precisely for this reason fascinating!!

I hope you can apply my idea to your passion!!

That has to be the nicest stamping jig I've ever seen!!!!!!! You have a fantastic melding of practical device with wonderful workmanship and rethinking of an old idea.


In fact it is so nice I'd be afraid to use it. One missed hammer blow and that beautiful bit of machining would be forever scared..

If this had been made more like a v-block it would be more size flexible and the clamps typically used to hold down round-stock in v-blocks would make the size of round that could be marked much larger.

Thanks for your comment, please note that I used a 4kg hammer to make it quick, you can still use a smaller hammer, with a little patience.

Like everything, attention must be paid for sure, it is possible to give a hammer blow even on a finger trying to plant a nail !!:lol:

Thanks for your comment, yes I agree with you, in hindsight I would have made some changes too but obviously there is a limit otherwise I would not have finished the project !


The idea of being able to stamp the round bars also arrived at the end of the project, however if I had made a device more centered on the round pieces, it would have been more difficult to write on the flat pieces!

A beautiful piece of machining, possibly the best stamping jig I have ever seen. It has the added advantage that it can be adapted to compensate for kerning if longer stampings are to be done and spaces need to be made to look acceptable.. What would be required is a list of the distances from the right hand of the letter to the right hand of the punch, the exception being 'A' and 'V' if used together. I have done a random measurement of my old ¼" letter punches and got these figures. 'D' = 3.6 mm, 'H' = 2.23 mm, 'I' = 4.63 mm, 'K' = 3.47 mm, 'M' = 2.38 mm, 'O' = 2.71 mm, 'W' (the widest letter) = 1.96 mm.

Goodmorning Hans, thanks so much for your fantastic message to me:i'm so proud that you liked my stamping jig, your suggestion is very useful, i was thinking
to add the distances that you wrote, on the back of the plate; i can make it with my laser and it can be a table to read like the screws table of pitch, diameter etc !! Have a nice day Hans and see you soon here ont this wonderful site !!

That's an absolutely beautiful build! Now if you could just make some way to prevent my dumb ass from putting the punches in upside down.

That scar would just be part of the story that AB-SHOP was talking about.
No matter how well made a tool has no validity unless it is used.

Some punches have a mark on the side facing you. if yours do not, grind a mark to remind yourself.

"Fantastica"

Thanks racene, happy that you like my project !! :)
