I have a common 6" Delta grinder. It sports two rests, one for each wheel. These rests are literally about 1.5" square.

What do all the cool people replace these with?

You can make yourself one of the talented Mr. Ishimura's adjustable grinding rests. Here's mine.

mostly i'd agree with that. There are some jobs where support is nice, like grinding a round end profile tool....otherwise tool bits are ground free hand, its easier imo

I usually just swing them down out of the way. I used to grind all my HSS and brazed carbide free hand, no rest. Now I use my HF tool grinder for the carbide and free hand the HSS.

I don't find 3-D free-hand grinding to do nearly as good a job as 2-D free-handing on a rest. With the rest, I can set the relief angle and concentrate on the shape in the other 2 dimensions.

I put a piece of 1/8" steel plate on top of the stupid little "table", one that was big enough to at least fit an HSS blank on it.

I thought that shelf was there to collect grinding dust and tell you when your wheel had worn down. Now you tell me it's to hold stuff on? Who knew... :p

One thing it does it get you a fine from OSHA if it's missing or more than 1/8 inch from the wheel.

If you can obtain/look at a copy of "Tool and cutter sharpening" by Harold Hall in the "Workshop Practice Series" - British publication, Harold describes the build of a jig similar to the one shown but with additional parts to expand its use on the bench grinder.

Regards Ian.

And if you can locate it, a series of articals by "Duplex" starting in the October 1948 Model Engineer headed "In the workshop" 21, a cutter grinding attatchment.

I can recommend Harold Halls book also, received it yesterday and could hardly put it down until I had read all of it..

In the "Tool and cutter sharpening" he describes one rest with a lot of attachments, for example drill sharpening and end mill sharpening. He describes a bit more advanced rest in his book "Milling, a complete course" but I dont have that one so I can't comment..

These may be some ideas.
