Easy "bench grinder to belt sander" no welds, or lathe..

[Tuomas]

This is my version from the very simple but still working bench grinder to belt sander build.

Takes about an hour to make.

Used 2.9$ bearings all other was surplus or scrap.

Video should include all needed info, but ask if you have questions.

Simple improvements. Bigger pulley for higher speed and belt tensioner. Still without welds or lathe. More info coming later.

Very nice conversion. I think an angle grinder with a cutoff wheel is one of the most useful tools ever created.

Though it's a non-standard practice I wonder if the belt grinder might be better with the tension arm and roller on the bottom side so that the backing platen isn't lost on the grinding side. It seems like a rigid enough design that the tensioner could work on the power side of the belt.

Tensioner is symmetrical, so it can be placed to bottom side too.
This is still "wip". Backing plate will be mounted later. Stay tuned, to see where i planned it.

Your toughts would work nicely too.

Here is what i planned..



Back plate is placed to bottom side..



Because i will make a stand for it, and tilt grinder 90 degrees.
Then i can use both sides of the belt. Straight surface, and also those both curved spots on wheels, to shape / finish curved pieces.



Also, i will tilt grind stone mount 90 degrees, and replace old stone with bigger and finer grade stone.

What do you think about that?

It's standard engineering practice to put a tension roller on the portion of the belt loop opposite the portion that's pulled by the motor, but like I said your tensioner looks rigid enough that I don't think it matters. I like to have a platen under a belt to prevent it from being deflected too much and rounding the apex of an edge. This is a well done conversion and if my grinder had enough guts I'd be doing it to mine.

Here is couple pictures about "wip"

Tilted the head. I had to relocate two mounting holes, it wasn't made symmetrical as i hoped. But that wasn't a problem.





Because new stone is heavier than original one.
I decided to add extra bearings to support it, to the left side.

Idea seems to work, now i just need to finish the stand and workpiece rests.

Thank you very much. I hope to get this finished next week.
Its very simple build and shouldn't take more than s day.. but those days seems to be very limited atm.

.... Win... Ten...
Homemade tool...

Thank you very much !

I didn't expect to reach that ten so soon.
It feels that it was just couple months ago when i made my first post.
