How can someone make a bench sander more precise if its table is not dead flat?

From a bench sander run of the mill $100 brand.

maybe place some aluminum plate
over the old one 1/8”
and some liquid epoxy
or some ‘filler glue’
under the plate
to keep it from flexing

joez, thanks for the pic. How far out is the table? You could easily sand the aluminum table. That is if you had a true surface to index from. Have you exhausted all adjustments on or at the table ?

The other problem with these sanders is the tables are too small. I covered the factory table with some flat particle board scrap then applied laminate to surface.I then built a second table for the belt sander.Now I can use either without having to move the tables back and forth.

Well, I’m not sure of the kind of accuracy you expect. Did you expect something like a planer, that you could just shove the wood over it and get results to some sort of accuracy? Did you put a sled on it? I’m at a loss here. I bought one similar, to sand the milling marks out of small pieces of wood that I have already milled to thickness. I’ll be building a sled to hold the wood so that it comes out like I want.

Sanders like this, improperly restrained, will make you wood lopsided just as quickly as a hand-held belt sander.

This sander is regards to just free handing grind/sharpen etc.. a plane blade.

I did not want to give to much detail because I got a remark like “wow cant wait for part 2 of this blog!”.

They should at least make a little hobbyist sander such as this to accommodate some precision needs.

That’s going to be a tough task, sharpening a plane blade on one of these. The sharpening tools made for this turn much slower and use really fine paper, and usually water. This belt sander is going to be way too aggressive for blade sharpening, unless you are really careful.
