my solution to a super small wheel

[JTknives]

I have always had a hard time cleaning up the hook on the end of the 2nd Amendment tangs. So I set out to come up with a solution I could work up on the cheep from stuff I had laying around. This is what I came up with and it works amazing. Thought I would share what worked for me just in case others are having this problem. I used a 1/4" diamater tungstion carbide rod and drilled a 1/4" hole in the grinder head. Slip the rod into the hole and presto easy solution. Don't want to run the belt very fast and not a lot of tension. But for what I needed it works perfect. To set tension I just pull the tooling arm forward till tight and lock the arm in place.

great solution!

earlier i was thinking of using a d2 rod but was concerned of the wear resistance against high speed moving sand belt. how is the carbide wear off? does it tremble when the joint point of belt runs though?

thanks.

Can't see any wear on the carbide.
As to the joint, you feel it go over the rod but I only use real flexy belts on it so it's not bad for what I use it for. I think what helps is that it's running slow so it's more of a bump you can expect.

JT, Hers another solution for people with small wheel holders. A machinist friend took a 1/4 inch steel rod and made a brass sleeve to fit standard bearings. The other wheel was a damaged 1/2 inch Beaumont wheel with the rubber removed to leave a wheel about 3/8 inch. These handle pretty much all the notches and tight spots. Larry

That's slick to.

It's ideas like this that I think really help those that don't have the funds for a "real" smh. Good idea and thanks for sharing.

Off topic, but what is the thickness of that blade pictured?

The blade is ground from 1/4" 5160 Barstock. I have been working on a v2 prototype of my 2nd Amendment. Dropping some weight with the holes in the tang and going to a flat grind should up the performance.

Ah, the 2nd Amendment knife. I remember that one! Always like it... Now where's the patented JT cord wrap?

Great idea on the carbide rod. Cuts out a tool arm change too... I imagine you could set up a couple diameters for some quick touch ups here and there, although it is hard to beat a rubber wheel's finish. Not an issue with 1/4" diameter obviously.

If you like my 2nd you will like the double edge version I'm working on.

I have used a rod as a small wheel for at least 10 years. It's great for finger hole clean up I of course turn the speed away down and run belts from 120 grit to 16. As well, I don't thing I've changed that rod which in my case is a 3/8" bolt

[JTknives]

Yeah when doing fine detail work I'm just cleaning up not removing a lot of material. I need a few other sizes

WD Pease makes a rod with bearings that serves the same way. Neato idea.
