[QUOTE=TonyKarol] I use an 80 grit Klingspor hook and loop backed paper that is also Stearate coated on my homemade sander - I get it from workshop supply here in Canada - its the best paper I have ever used, and lasts a LONG time - spruce for days, rosewoods for wuite a while - liek someone mentioned, clean off any stuck on resin clumps ASAP as they just load and burn stuff. It comes in 50 yard roles, both 3 and 4.5 inch wide ...[/QUOTE]



That's exactly what I use (except 60 and 100 grit) and it does last forever. I built three complete guitars of cherry with 100 grit and it still looked like new. Ran my mad-rose back through it and it was one ball of gum.    So I put on the 60 grit for the mad-rose and no gumming problem at all. I've got a 50 yard roll of each and it will last me through all the guitars I plan to build.

Hesh, Those pictures are great! I don't think I have ever caught a good look at that clip because it is kinda awkward to see. You motivated me to take a look at how I wind(especially because I do start at the sprung side, and it has given me no issues).

I realised that when I start winding I clip the paper(and this is on the sprung side) then I wind the drum once around(to get the paper alighned. I had ahold of the drum through the end with my thumb on the sand paper. When I straighten and snug the paper I noticed the I pulled the paper tight, it also pulled back on the spring. Then as I wind I keep the paper tight with my right hand as I guide the paper onto the drum with my left. When I get to the open end my right hand thumb is placed on the paper and I pinch the fixed clip open with my index finger. I feed the paper through the clip with my left hand, still holding the paper and clip with my right hand. I then grab the tip of the paper(It is easy to grab on the open end of the drum) and wiggle it to get it seated well and give it a good pull as I release the paper and clip with my right hand. After watching the spring side through the process, I noted that I never release tension on the spring(looking at the spring clip as best I could it looked like it may have slipped a bit, but was still tensioned). I also tried reversing the process and finishing on the sprung clip, but could never get the same tension(probably because I am just not used to doing it that way).

I took a picture of my drum. It has 60 grit on it right now. As memory serves, I surfaced approx 20 Spruce soundboards, 4 B/S sets of Koa, 2 B/S sets of Pink Ivory, 2 B/S sets of Myrtle, 2 B/S sets of Sapele. Surfaced Several set billets, 2 Snakewood Fretboards, and a handful of other things that are not coming to mind right now.



This is a shot of the back of the role(cloth backed Aluminum Ox). I don't know what brand the paper is, but it seems to do a good job.


Peace,Rich

[QUOTE=Dean]You need much more vacuum! The dust is going around and being compressed back between the paper and the wood causing load-up and a tremendous amount of friction heat. The cleaner sticks help a little, but once you have burnt resin stripes, games over. Then you need to buy Wurth pitch and resin remover. Put some in a coffee can and let your belt soak for awhile, take out and rinse and you will believe you have a brand new belt! I use it for my hand-held belt sander, my 16/32 and my 43" wide belt. Here's a link. Go to page 10.

Man that stuff is really great.  I had a disc on my Drill Press Thickness Sander that was totally gooped up from sanding black and maple veneer stacks for a rosette.  Found a bottle of Wurth that I had gotten at the woodworking show last year, sprayed the disc, brushed it with a gentle brush, rinsed it and all the goo was gone. Looks like a new disc.  Amazing.  I'll be buying some.  They told me it was good when I got the sample.  It is also supposed to be good for de-pitching saw blades.

I'm not sure if you all got my THANK YOU for all of the help with this problem. I got some 80 grit paper this past week and have already run 8 back and side sets through the sander with the same maple that was giving me a hard time and the paper is still in good shape, I dont have any burning, and the paper is no longer loading like it was. I also got it wrapped on the drum in the correct direction and it doesnt show any signs of tearing.

THANK YOU !!

Looks like I got the problem solved ! The surface is a little coarser than I am used to, but the wood will get a lot more sanding anyway so this is no problem.
