How to Metal Stamp on Mouthpiece

[picctpt33]

I have lots of mouthpieces with different throats and backbores that are not marked. How would one go about stamping the size of the throat or backbore on the mouthpiece at home?

I have a metal stamping numbers kit, but I'm not sure how to secure the mouthpiece to be able to stamp it.

Any ideas are welcome!

When I vented the valves on my horns, I took a piece of scrap 2x4, took a router & dug out a "trench" that held them quite nicely.

I suppose you could do the same with a generic mpc outline.

You can buy a throat gage, essentially a tapered cylinder with marks to indicate the hole (throat) size.

Backbore, what Tim said, or use modeling clay or similar and insert into the backbore to make a mold then measure or compare to a reference backbore online or where ever.

Basically I'm asking what kind of surface I could use to place the mouthpiece on so that it would be secure for when I would stamp the mouthpiece.

On Greg Black's website, you can see that he has a metal bench block with indentations of trumpet, trombone, and tuba mouthpieces:

As I do not have a block like this, I'm wondering if anyone has any ideas of what else I could use

Member trpthrld gave the best advice for a DIY approach, I think. I would add you may want to use a piece of hardwood rather than pine or douglas fir. If you do not have experience stamping on metal I would practice on a scrap piece of brass. You will want an accurate blow from the hammer, everything square, with the correct amount of force for the desired depth. You may want to hold the stamping die with a pair of channel locks to avoid bone injury.

The easiest thing to do would be to use thermoplastic to make a holder. (Search thermoplastic beads on Amazon)

Heat the beads in some hot water, carefully form into a block, push a mouthpiece into the block to make an impression, let cool to harden. Of course this would only work for one blank shape - just re-heat the block to make another impression.

thank you for these ideas

or

for a less permanent solution

print out a small tag on a laser printer so the ink won't run
in 8 or 9 point Helvetica

then cut it to size

wrap it with clear heat shrink tubing with plenty of extra

shrink it

Craft stores sell a tool for holding the stamps that works great. It looks like a stick with a ring at the end. It makes it easy to hold the stamp nice and straight. Then get an aluminum V-block from McMaster or similar. A cheap one. Then you need a brass or plastic ring that fits on the end of the shank and is about the same size as the big end. Then lay it in the v-block and you are set. I usual put done paper in the v block to keep from scarring the mouthpiece but you are only gonna use a little bit of force with the hammer. Use a small brass stamping hammer from sane you get the stamp holder from. None of this stuff is very much money
