Toolpost turret was a bit battered and bruised, time for a trim...

When that's done, it's time to give the cross slide nut a tweak.
Had to remove the felt swarf keeper-outerer, coz it's getting too close to the side of the channel. Nearly time to start adjustment towards the other side.

Now I can make the chuck key the way I should have....
Eight years ago.
Shim the freshly dressed turret to take a .3mm(.012") cut.
Square turret to chuck, off we go...

 

[timmeh]

First use of bull gear indexing for milling.
Using various thickness of old steel packing strap(the stuff that gets ratcheted up tight and crimped with or without ferrules, on boxes, crates, pallets and bundles of stuff for transport) to shim turret and tool holder.

 

[timmeh]

Adjustable stop for tool holder.
Final cut.
Carriage stop.
Finished key.

Much purtier....

Thanks for sharing your mods. Lots of interesting stuff.

For the Dremel mount, it looks like you started with a nut that was the right size and thread? Is that a grub screw to lock in the Dremel?

I've thought about making something similar but I wasn't sure how securely the Dremel is held since it is only a few threads of engagement at the end of tool. How much does the unsecured end bounce around? Any concerns with the quality of the cuts it can make?

Thanks,

Craig

Yes, nut is correct size(3/4, 10 or 11 TPI) no grub screw, just nipped up firm(it's only a plastic housing), didn't notice any vibration, too busy watching the pointy end.
Small cuts, .5mm(.020") at the start, .15mm(.006") to finish and spring(deflection) cut after each cut.
Using 1/8 carbide burr as milling cutter.
Adjusting "carriage stop" as I go, to prevent cutter grabbing in the radius, particularly because I'm climb milling.
