A shear tool, also called a vertical shear tool, is a specialty tool used to take a fine cut to produce a very fine finish in most materials. It has an angled vertical cutting edge but has no relief angles so it can only go maybe 0.001-0.003 deep. It is intended only for finishing.
Here is Tubal Cain's video about it:
I don't own one, nor do I feel the need for one. However, it has been raised enough that I accepted the challenge of optimizing the angles on one and then grinding a finishing tool to compete with it. Then we'll see just how good it is and if my finishing tool can compete with it.

Shear tool works great on gummy, garbage steel like 1018. No optimization of angles needed, just get it in the ball park. Moltrechts description in the shaper section of his book on machining gets it done for me. I use the same shear tool on my little 8" shaper and my 10EE, no problem, rough ground the tool using an angle grinder, finish on belt sander. I don't use it a lot, but for long slender workpieces where flex can be and issue, it works wonders with very light cuts, one or two tenths up to a thou or two. On the shaper I take heavier cuts but still light by comparison. Great tool IMO.

Thanks, Aukai. I guess its a matter of perspective. I am a full time caregiver for my wife and part time for her Mom and my Mom. Our Moms are in their 90's, don't drive and everything is a crisis but I am so grateful to have all of them in my life, even though every minute seems to be filled, and I feel blessed.

Kept meaning to PM you, Mike. Did you ever buy that 2 X 42 belt sander? If so, how do you like it?

Mikey I know what you are dealing with. I am the sole care provider for my elderly mother who turned 100 in August. She is joy to have around. Mom is in relatively good health but getting frailer and needs lots of assistance with the necessities of life.

A grizzly belt sander showed on my local CL I went to grizzly's website to check it out and saw this. http://www.grizzly.com/products/Grizzly-Combo-Belt-Sander-Grinder/H7760
And wondered how hard it would be to adapt one side of a bench grinder to a belt sander. Seems like it would be easier to do this than build a belt sander from scratch. I looked at the parts list and it looked like you could buy all the parts for less than $50.

The hardest part will be fabricating the side plate that forms the chassis of the belt sander and there must be some provision for attaching it to the side of the motor. Once you do that, you can order replacement wheels and tracking assembly from Sears.
Or you can buy a 2x48 multitool attachment for almost $300, or you can build a 2 X 72 for about the same money.
You could also just keep an eye out for a Sears belt sander on CL. It will eventually show up.

Yup, I bought that Dayton, I put better belt on it, have not updated the platen and will have to carve out some pot metal to put coarse belts on as there is not enough clearance. That said for the $150 I paid it beats the USA built Kalamazoo 1 inch belt sander I have by a mile. I have been busy around the farm so shop projects have taken a back seat. Over all I am happy with it for the money.
Best Regards
michael
