It seems to me that there is NO WAY I can achieve the angle that is on that roundnose with the fixture I have.

If anyone has a camera that would allow a closeup of a properly ground roundnose, while mounted in the sharpening fixture, I would sure appreciate it.
Take a gander at the instructions that came with the Sharpening Jig. I again noticed these instructions are a little hard to figure out. However once the organization of the paper is understood, the instructions become more clear.

About the Roundnose - This is on page 7. moving the jig between 1/16" and 1/4" from the sander will vary the radius of the nose very much. The 15 degree angle seems to work for me - as well as the smaller radius. Yes, the 15 deg. angle is quite a change from the factory grind.

Just tighten down the knob when the chisel touches and let the jig do the work.

I love my Strip Sander but I would never try to compare it to my Tormek (which with attachments cost more than I paid for my 500 new). The Tormek has accessories that turn chisel grinding into a science instead of an art.

Again, at the risk of being repetitive, the Chisel attachment for the strip sander overcomes a lot of what people have posted about this thread. This attachemnet has been able to successfully shapen small as well as large chisels. Following the original contour of what it is to be sharpened is a snap. Just set the angle to match the contour and away you go. This item is beautiful in its simplicity.You really should check this out.

You are correct, in terms of speed but I would not consider it as a replacement. I am glad I have the luxury of having both.

Just to whet your interest, I'll be showing how to use the strip sander and sharpening attachment in the December 22, 2007 Sawdust Session. I'll also be showing how to adapt it to do plane irons, both small and large. It isn't just for chisels anymore.

With all good wishes,

I posted earlier message about using sharpening attachment. Still trying to get ahandle on the proper use. What ever I am doing wrong it just does not allow me to use this with my shopsmith either on the main table or the extension table. Magic answers apreciated.
Thanks to all Bob Fox

Bob - Here's the most magical answer I can think of http://www.shopsmithacademy.com/Sawdust_Sessions.htm

Scroll down to Sawdust Session #4 - inside of that session and you will see the #3 part is about using the sharpening jig. Also another piece of magic - look at #8 on the blackboard.

I'm pretty sure this is the video that was mentioned earlier.

I believe we have a slight miscommunication. The video reference was intended to take you to the Sawdust Session videos. Try clicking on this link:

http://www.shopsmithacademy.com/shopvid ... hisles.htm

Elsewhere in this thread there has been some discussion about chisels that were shorter than others - maybe this is your problem. The fixture that we are talking about was designed specifically for Shopsmith chisels.
