Tool Vevor Drill Bit Sharpener Improved

[TorontoBuilder]

I never noticed before but ZFZL store for some reason separated my 5 collets into 2 parcels WTF?

Parcel 1 arrived today. Parcel 2 appears to be lost and stuck at some airport in China... likely because it is such a small package. Maybe it fell behind something, or off a conveyor, or whatever. But why the hell not ship it as one parcel?

So I now have a ER20 collet in 1mm. Boy is that a small and one ER25 collet in 15mm

I got a a shipping update, seems some of my collets are due to arrive today.

Mine are months away. I think they are going via the Panama Canal......

Love your model. Is that really how the motor is mounted?

FINALLY GOT MY STONE SCREW LOOSE! I bent the Allen key with my fingers first, then got my small M12 impact driver out with an adapter. Took an hour of brappp a pappp pappp, brappp a pappp pappp, brappp a pappp pappp, and then just suddenly it was off! I feared I was gunna be drilling out the screw. Holy Moses! Yes, it is a regular thread, the stone turns counter clockwise, and it is counter clockwise to remove.

Edit - I should add that it has a custom arbour on the motor shaft that is retained with 3 set screws. So it should be possible to make arbours for other stones.

Oh yes, we can definitely make a custom hub/arbor and mount any wheel we please to the motor. This is why I wanted to buy another one.

but damn I modeled the hub with only two grub screws. revision required to the hub and motor shaft

I was looking to see if we could cut flats for a wrench. I literally bent a 5mm Allen key trying to undo that keeper screw.

Do we know if there are detents for the arbour screws? If not, removing the arbour might mess up the wheel position.

In my mind's eye I was seeing various plates to allow custom angles in variable planes. I started to look at endmill geometry but the nursing mafia I'm married to figured out I was out in the shop alone and that was that for getting anything else done.

I modeled up the grinding seat..

I'm pretty sure that I have the right anglular offsets and such, but I think they have made the 90 degree stops differently than I have. I'' change what i've done later.

They use a 35mm ID and 47mm OD bearing 6807-2RS with the tool holder pressed into the ID.
