Sharpening 28mm Rotary Blades?

[YukonJake]

Has anyone tackled sharpening 28mm rotary blades? If so, are there jigs out there that would fit the T8?

Thanks much.

The only jig I know of is described on Rich Colvin's treasure trove of a website.

It requires *a bit* of craftmanship, though...

Tormek has a Round Blade Sharpening Attachment:https://tormek.com/en/products/culinary/culinary-accessories/rbs-140-round-blade-sharpening-attachment

But it fits the T2 sharpener only.

A creative mind and a bit of ingenuity can go a long way, which is amply evident in all that Rich Colvin does. 

The manual for the RB-140 is here.  It states that the range of blade sizes it works with is 80-140mm.  But If the mounting shaft size is 12mm, as every other Tormek jig is, it will likely "fit" on the standard USB. From there, it could be just figuring out how to make it work.  28mm is pretty small (1.1"), so that could be your biggest challenge and Rich's jig may be a better approach. 

Do a search on the forum for the jig, using the term "RBS-140 Round Blade" and read what discussion there has been about this jig and round blades in general.  It does return some irrelevant stuff.
