Latest Project: A Universal Milling and Grinding Fixture (see pics)

[jgedde]

If I were to make dozens of threading tools with the tip dressed as you ask, I'd probably just dress a wheel with the correct profile and go to it. I could use this fixture to hold the bit for that... Yes, one would not need to compute the angle...

But that would be overkill for just one or two.

I usually just grind that end dress by hand or leave it sharp...

Here's the latest progress...

Safety First... Lathe needs to be unplugged for what's next...



The graduating setup... Rotary table laying on a block of wood on the lathe bed. It's bolted to a faceplate to square it up. A sharp 60 degree bit is laying sideways in the toolholder. Numbering was done using an empty toolholder as a guide for the stamps:


Engraving underway:


The second axis support being made:


Finished support:


Assembled, welded and ground square. The weld quality could be better but I was fighting with a helmet that kept flashing me and was too lazy to change out the 0.023 wire for 0.035. Fill and paint will cover up the ugliness. Axis supports and gussets made up and welded. Base turret graduated and numbered... Like that crooked Harbor Freight 3 and weak 4?. I won't be using those stamps again for the other axes... Plus the numbers are a bit large aesthetically speaking.
