USB Spacer for the DBS-22

Flat Ground on USB Spacer

Overview

Micha Schmid posted this on the Tormek forum in 2021. He noted how it makes it easer and faster to set the USB relative to the grindstone, and it also helps ensure the stone is consistently flat relative to the Universal Support Bar.

Keld Petersen milled a flat surface on the USB spacer, making it easier to remove. If it is difficult to remove the spacer after the height of the USB is set, you can turn the grinding stone by hand and the spacer will loosen. The lower picture on the right shows the spacer with the milled flat.

Notes on Making One

It is made from aluminium. The dimensional information are:

• the width is greather than the grindstone:
  • the grindstone is 50mm wide on the T-8, and
  • the grindstone is 40mm wide on the T-4,
• there is a 12mm bore thru the center, and
• the walls are 14mm, meaning the total diameter is 40mm. This 14mm width is equal to the distance which would be set when using the Setting Template (as shown on pg. 6 in the instruction manual for the DBS-22 Drill Bit Sharpening Attachment).

I made a 3D-printed version of Keld's design. The files for this are below; use the one you need for your 3D printer.

DBS-22_USB_Spacer_Text_Added.3mf - This is the same as the one below; only it has text added to the end of the piece as shown in the picture to the left. If you have a 3D printer which can select between different rolls of filament (e.g., a Bambu Labs AMS) this is nice. DBS-22_USB_Spacer.3mf DBS-22_USB_Spacer.step DBS-22_USB_Spacer.stl
