Hi David,

I’m glad you liked the article but I didn’t write it.  Mikey did and he’s got me sold on using a belt sander also.  Although I still use a grinder to rough shape a new tool bits before switching to the sander.  My Harbor Freight 1×30 belt sander doesn’t have enough horsepower or surface area to quickly remove a lot of HSS. 

      

 

I also use a belt sander to hone cutters after shaping on a grinder. I bought the Grizzly 1×30 at least ten years ago for about $30.00 Originally bought for wood. 4 months ago I built a two wheel 1×42 sander to use on metal only. Works great, two wheel sanders track easily, especially if both wheels are crowned.Cost nothing to build ,had motor and every thing lying around.I used a 1hp motor because I had it, overkill probably.I bought belts that are for metal removal only, big difference from the 1×30 belts I used to use.Much faster than wood type belts and a nice smooth grind.I still use the 1×30 for wood only.

I got the design from the web ,do not recall the site.Excellent plans.The only changes I made to the plans were in the materials used.I used 3/4″ plywood for the base and the frame.Plans called for two pieces of  1/2″x 4″ x 18″ aluminum for the frame.

Would have been expensive for the aluminum and the plywood worked out well.

Hi Rob.

I read your piece on grinding lathe tools with a belt sander. I could not agree with your more. I have done it both with a sander and a grinder. You said build a god tool rest. That part should have been in bold and underlined. Without a good tool rest the best grinder or sander will not help very much. The gray wheels that come on the small cheep grinder we all have are only good for paper weights. Buy a good White wheel, a pink one and maybe a green one for carbide. With the right grinding wheel, a diamond point dresser and a good tool rest you will be surprised how good your results will be.

Now for a bit of a joke. Do not leave your good grinding wheels on your grinder unless you can be sure your bother-in-law will not screw them up with his lawn equipment blades. Also beware of your wife, her hedge clipper blade will destroy your green wheel.
