Some ideas for Tripan tools

**Okapi** · Dec 1, 2014, 05:58 PM

Just some pictures to illustrate my tools actually in development, on the link you can go on my page with all Tripan tools I've made.

A tool for making concave brass cups.

And a study on a automatic threading tool with a 15mm. withdrawal for finishing on a large diameter.

Interesting, Okapi. Would you have videos on how these two tools work?

Actually not, but as they are other people who ask me for, I have to take time for making something clean, when I make the proofing of the concave tool next days if possible.

Hi Okapi,

Nice work. If you'd post some details on a completed tool, I'd be glad to add it to the database.

The tools in development look great.

Thanks for your interest Ken,
They are completed tools on my link, do you want pictures taken from this database ?

If you'd be willing to post each completed tool in its own thread with a brief description of materials, intended usage, and any construction technique you feel merits highlighting, that would be ideal. I'll be glad to add each one to the database directly.

Here is a video of the action on trapezoïdal threading, bad image quality, but I don't know if i can put a HD video for all people, it needs high velocity connection
filetage mode automatique trapézoïdal | lecollectionneur.ch | Pierre_G.
This is a 9mm.X2mm. at 30°(european normalisation) with ETG85 steel, it don't need the use of the opposite tool(I don't know the word for "lunette à suivre") with HSS tool made on the sharpening tool and optical contro gauge for the right angle.
