Plans for a Diamond Nib Holder for a Surface Grinder

Glenn recently made a Nib holder from scratch for his surface grinder. You can buy one from MSC for about $25-35, or you can make one with a few hours of effort out of parts from your scrap bin.

Here’s what Glenn had to say about his Nib Holder:

“I recently made a Diamond Nib Holder for dressing the wheels on my new surface grinder. It’s a very simplistic design derived from the common off-the-shelf Nib holders that you see in MSC, Enco, etc. catalogs. Those, however, are typically castings or welded parts. (see last photo above). My version is fully machined, ground, and bolted together. I used A2 tool steel. The part is approximately 5″ long, 2″ wide, and 1-3/4″ tall. The base plate is 1/4″ thick. The top block is approximately 1-1/2″ square before machining the angle on it.

This tool is a good example of how one might use a 15 degree Angle Block to position the top of the Nib Holder for milling and drilling at the desired angle position for the diamond dresser.

I also used my new surface grinder (new to me, at least!) to put a nice finish on all of the surfaces of the tool.

Thanks for sharing you plans Glenn!
