A couple months ago I acquired an older used 16/32 Performax drum sander. I find it next impossible to make the clip on the right end of the drum hold the sand paper. The clip is poorly designed and takes more strength than I possess. I thought the answer to this would be to convert to Hook and Loop and bought the conversion kit from Grizzly. I cannot make the materials from Grizzly fit on the drum of the Performax. Starting the rap of the hook material on the left end of the drum per instructions, the first turn results in an overlap of about 1 1/2 inch. This seems impossible to avoid because of the width of the hook backing material. There are Performax owners who have used the Grizzly material. How did they make it work?

Hi Hutweb-
I have the same sander. It can be a little challenging to change belts. I have no experience with the hook and loop set up. But a question … is the wrap 3” wide. Are you orienting the diagonally cut sides of the wrap so that they are at the outsides of the drum?
When you wrapped your belts using the original pinch clamps did you start at the outside end of the drum and end at the motor end of the drum ? Did you get the end of the wrap between the lever and pinch pad ? What I do is pull the lever up towards the drum surface with one finger. Feed the wrap between the clamp and pinch pad. Once I let go, the clamp grabs the wrap and the spring then pulls it towards the drum axle, tightening the wrap.
Heres a view from the motor end.

Hi JayCee 123,
The hook portion of the conversion kit from Grizzly is 5 inches wide. I believe this causes the problem because this kit is designed for a drum of a larger diameter. Starting on the left or out side as per instructions the second turn ends up over laping the first. I do not understand your second question.
When I rapped the original belts I start at the outside but the problem lies with an apparently defective damaged clamp on the motor end. Even my much stronger younger son can’t make the clamp work!
That’s why I need to convert to H/L. I hope I have answered all of your questions. And thanks for responding.

I used the conversion kit to convert my grizzly 18/36 open end sander. I used an old belt for the pattern and cut hook part to size. For my sander that meant cutting both the width and length of the roll. I used the clamps to secure both ends. A couple of things I didn’t think about before I did this:
1. It increases the diameter of the drum which changes the length of your sandpaper. You cannot use a precut belt for the sander. Not a huge deal, I now buy the 50’ rolls of paper.
2. The hook portion creates a “cushion” on the roller, to keep the work from bogging down while sanding I have reduce my depth of cut. Again not a problem, unless you are like me and ruin a nice piece of wood on your first test.
3. Grizzly also recommends that you use reinforced packing tape to rap the ends of the sandpaper, I have tried both ways and didn’t notice a difference. But for peace of mind I use the packing tape.
Hope this helps.

Just a note on the hook and loop concept on the 16-32. I did it several years ago and it saved my fingers (they are small “woman’s” hands and I still had trouble. As time went on, I found that the hook and loop actually added a little variability to the top of a board that was being sanded. It doesn’t happen all the time but if I take off anything more that 1/8 or < 1/4 turn on the handle, it tends to give me a rippled surface. Just a thought. There are times when I love the hook and loop (when I’m putting on the sandpaper) and times I hate it. By the way, I still make my sanding strips long enough to clip on so actually, I’ve saved nothing!! You do get used to the lever with time.
Just a thought…

I appreciate these responses but have yet to receive a reply from someone who has used the Hook and Loop conversion kit from Grizzly on their Performax 16/32. How did you do it? Does the Hook portion need to be cut down to 3 inches wide to make it work? Would like to know because this would cure a lot of problems and I can use up these materials.
Thanks,
Tom

Tom, you had a guy tell you what he did with a sander thematic uses 3” wide paper and his explanation was great. I plan to get that kit myself and put it on mine just as he did.

By cutting the length and width of the hook sticky.

hutweb, I have a Supermax 19-38 and have the Grizzly hook and loop conversion on it. I had the same trouble you are experiencing. I would spend 20 minutes changing sandpaper that was ruined because it would loosen up or get burned. My fingers would be sore from fighting the clamp on the one side and I hated it. I would never change grits because of how difficult it was. When I got the kit from Grizzly, I also couldn’t get the hook part to spiral correctly and ended up not doing a spiral wrap and instead, I cut it to the length needed to wrap around the drum and staggered the joints. I wrap the sandpaper in a spiral like it’s normally done and use the packing tape on the ends. I’ve not had any problems but I do take care when replacing the sandpaper to put a finger down on the hook when I’m going to pull the sandpaper off where the joints are. . What I really like is the hook and loop provides just the slightest cushion which keeps the sandpaper from getting too hot and therefore doesn’t burn the wood or ruin the sandpaper. I also use the 50 foot rolls but the sandpaper lasts so long that I will never have to reorder sandpaper. What used to take 20 minutes, now takes 2 minutes and I don’t have sore fingers.

Hi R0b,
I am trying to avoid reducing the width of the Hook material from Grizzly from about 5 inches to three. Rob you have apparently successfully made this conversion kit work. You make the statement, “I cut it to the length needed to wrap around the drum and staggered the joints”. What do you mean by stagger the joints? Did you reduce the width down to 3 inches?
Thanks,
Tom

I have not converted a drum sander but recently built my own.

Instead of the Grizzly conversion kit, I bought Velcro from Amazon. I got the Industrial Strength Velcro which was 2” x 15 feet.. it is half the cost of the Grizzly and really sticky. It has worked very well and the narrower width makes it easier to wrap.

After your response I tried to fine the Velcro on Amazon. There is a large number of Velcro items listed on Amazon. Can you be more specific as to which one you bought.
I have given up on making the Grizzly kit work. Of all of the numerous responses on this site that tried to address this problem no one actually explained how to do it. Grizzly need to warn customers that their kit will not work on other sanders or come out with a new product that will work on different makes. Thanks for all your help.

I referenced the Industrial Strength Velcro in my previous post. If you do a search in Amazon for it, you will find it.

Thanks for the idea/tip Redoak, I placed an order for the 2” X 15’ roll and just one roll of some 3” X 50’ 120 grit paper. That should give me 7 wraps of 120 grit and if the hook and loop really runs cooler the paper should last a lot longer. I’ll probably get other grits but I started with that to see how it goes.
