Beautiful work.
I don't know how to word this, I don't want you to consider it a challenge or an attempt to advise you, just curious.
Here goes, I heard from a highly regarded moderator of another forum that gringing/sharpening with a belt sander leads to slight rounding of the edges due to the belt's efforts to lift off the bed.
Have you not experienced this?

I got the wheels from one of the model engineering suppliers, not sure which one Tom. You often see them for sale at Model Engineering Exhibitions as well, they are'nt expensive. I think the best ones I've seen for sale were made in Germany.
Seems lots of folks use belt sanders to sharpen tools Steve and I've not had any problems.
For some tools the hollow grind you get from a wheel is good but for other stuff I prefer a flat grind.
I particularly like being able to swap grades easily, I can even do it with the machine running! I based my system on this:

I believe Sorby have been sharpening their tools on a belt system for many years.
I'd like one of their grinders but they are a bit spendy!

Thanks for posting the pics. All of those are very useful tools, and good project ideas for those of us looking for something to build. The nudger and spring center are something I've been meaning to make for a while now, but unfortunately my project list grows faster than I can build them.
Nice job on the design of the tangential tool holder. I've seen others with questionable clamping designs, but yours looks rock solid.

Thanks for the numbers. That's my next project. But it won't be nearly as beautiful as yours!!
What's the up angle on the sharpening fixture? Is the blade 90 degrees to the belt, and laying in the fixture at 45?

Thanks for the comments guys. The tool bit sits in a vee cut into the jig, which is at 30 degrees. If you need more pics let me know.
Edit: have a look at the jig here, does it help?
