Belt Sander 2000x50 / 72"x2" - RobWilson - 01-21-2016
Evening Chaps
It being to cold for shop work in the evenings ,especially when one has been out in the cold and wet all day .I thought I would make a start on my belt sander project ,
I have just about all the materials about 95% . The last to arrive was the VFD and the 2.2Kw 2800rpm flange mount motor .

I bummed a wee bit of 180 mm dia ally bar to make the drive pulley and a larger contact wheel from .

And these are some of those toxic to North American belts
, I hear Marmite and Vegemite are also banned LOL ( I personally love the stuff ) ![[Image: P1070987_zpsiye1jyzw.jpg]](http://s1066.photobucket.com/user/RobWilson100/media/Belt%20Sander%202000x50/P1070987_zpsiye1jyzw.jpg.html)
The wheels I probably will probably not use , I plan to make my own ,part of that missing 5% is rubber
So the design so far , this is still very much a work in progress as I have a lot of ideas to flesh out .

Done a wee bit work on the three contact wheel head and the larger 8" contact wheel designs .
The yellow line depicts the belt path ,the various ways it can be laced .

The above will have 70mm,100mm and 130mm rubber contact wheels .

Looking good Rob. I'll be watching this thread since one of those tools is on my long list of projects.

Are you planning on buying or making the contact wheels?
Fine looking belt grinder! My own belt grinder build stalled. :(

Hi Al , I am planning on casting my own wheels in Urethane , just pondering on what Durometer to get , probably a Shore A 50 ish lol .
How far along is your build ?
Cheers Rob

All the grinding debris and dirt on the belt will get embedded into the two polyurethane wheels.

Hi Dave ,
That's not a problem as the rubber contact wheels are consumable ,and being rubber it does not mess with the belts sanding grit/medium as a solid wheel would ,
the reason for lacing the belt in such a way means the belt conforms to more of the wheel circumference .instead of just 45 degrees of contact there is 180 degrees of contact .
Some of the wheels I will be making will be down to one inch in diameter so without lacing under two wheels there would be very little radius to work with .
Clear as mud , lol
Cheers Rob

You can always cast extra wheels, if the double-loop puts too much wear on the contact wheels.
I've considered a similar belt arrangement for a tube-notching fixture for a belt grinder.
I bought all the bits & pieces (almost said "bits & Bobs, but don't want to offend any Roberts), and have the main frame built.
It's the work table(s) which have stalled me. I want to have one accessory table which the work is clamped to the table, and the table slides on rails -- sort of like a surface grinder. The problem is I want it to be "universal", i.e. tilt in 2 axis. It's getting complicated.
Part of the 'design brief' for my belt grinder is that it is to be laser or water-jet cut from 1/4" plate steel and welded together.
Keep us posted on the urethane casting. I'd be extremely interested in knowing more about that.
