Laguna Supermax 25-50 Drum sander

You probably already know this, but a crepe rubber block for cleaning the sandpaper is a must-have.

Yep – $14 from woodcraft supply

Got one from Amazon on order, I cut a roll today for it off a large roll and put it on. I got the right length but I had at least 1/2-3/4" needed more to cover the whole drum. My rolls are 3" do I need wider rolls? Maybe 3 1/8"

I looked at several of my Supermax boxes and the size is not mentioned there just that it is for the 25" sander.
I measured several rolls width and got 3-1/32" for all of them.  I think they are nominally 3".
If it's any help I dont think it matters if when you wrap it on there is a bit of gap between the adjacent wraps even 1/16" which might help you cover the width.  The fit has to do with the angle and length you cut the leading and trailng edges and that the overall length is long enough. There is a template for this in the operator's manual.  I didnt have to cut any.  

Mine cover the width of the drum.  But they tell you to leave a gap at the last wrap to allow the sander to pull things tight as the paper stretches.

It would be worth having one genuine Supermax roll just to use as a template if making them up off of a bulk roll.

Can't seem to find rolls of 36 grit, anyone have any ideas?

I got mine from Supergrit in 50 yard long rolls.

Supermax sells the individual rolls in packs of 3.

I didn't see bulk rolls anywhere that were any less expensive than the pre-cut Supermax rolls .

I ran a 24" double drum Grizzly a few years ago and got rolls from them.  Call as they have more than whats on the website.

I cut a plywood template that I used to cut the angle on the belt.  Worked well.

I skipped the drum sanders and went with a 15" Grizzly wide belt, open end sander.  Works great on glued up panels.  And easy to change grits, just push a lever, and slip on a different belt. Cool thing about the sander is if you sand both sides as you go, helps to flatten panels.  You have to pre- try your wood, as the sander is not limber like the drum sanders, and you might jamb it up with a piece too thick for your setting.  I put the end of the panel between the rollers to adjust it, start a little loose and tighten it up till it is sanding right.  Lots faster than drum sanders.
