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.:rolleyes:
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.
Ken
Thanks for your interest Ken,
They are completed tools on my link, do you want pictures taken from this database ?
Nice work, Okapi :welcome:
Thanks, Okapi. Looking forward to further posts on these tools.
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.Quote:

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.
Nice work Pierre. I really like the alternative design of the concave cutter. Most homemade radius cutters are based off Steve Bedair's design.

The idea for the concave tool was to make some radius in the front of the piece, and with this one it's possible to go on a 5mm. radius, if I make a support with a recess it's possible to go to 1mm. theorically, it's not make for radius more than 30mm. the diameter of the cutting rod is too small on this model.
For bigger concave radius, I use the convex model with the head reversed under the center line.
Here is the completed page about Tripan tools, they are some others to photography when i've time…
