Custom Sanding Belts for Linisher (Belt Sander)

08/30/2009 5:48 PM

Hi all

I recently refurbished an old 6 " linisher (belt sander) but found the belts hard to obtain. I got some from an auction site but am not happy with the build since they click at the overlapped seam. Has anyone had the experience of making up custom sanding belts and can anyone give me advice on methods of joining the two ends smoothly. Glues, bonding tapes, methods of reducing the thickness if I have to use lap joints, how to butt join the ends, suppliers of belt rolls etc. Any advice appreciated from those in the know.

Check this site: WWW.klingspor.com for sanding belts. I too wanted to make up my own belts, but found that the process for joining the ends is proprietary by belt manufacturers. It's more than just splicing and gluing the ends.

I have found cutting the belt at an angle from right to left as viewed works and gives far less judder as the joint moves over the wheels. I am talking of a diagonal cut, which should be ~ 20 to 45 degrees.

Before joining (as described in the site above, you may want to 'line' the inside of the sanding roll, this will make the driven belt more smooth.

Stick the sanding belt to a substrate such as denim, leave where the belt will be glued as bear belt. Stick the backing onto the belt and leave the glue to dry.

Then stick the belt together. It should be better with not much judder?.

Another way is to stick the denim or any substrate over the original join in the belt. But chamfer the edges so they go down to zero.

Sorry, this is a bad day for explanations! I hope this is of help.

Take care

Thanks for all the answers. I did have a go by cutting off the lap joint and butting it together on a piece of thin backing fabric from a curtain shop. I used evo stick and whilst there was a little stretching at the seam 0.5 mm it did work with much less chatter. I will follow up on your advice but probably won`t order in bulk because its for the odd job in the workshop and won`t be heavily used. By cutting and rejoining I was still within adjustment so I was lucky there. Also I might at some stage try a corser grade as the joint may not be so apparent. Thanks again.

Hello Pj3,

I am glad you have tried one remidy and it works. Perhaps, with a little lateral thinking, the drive and or guide wheels could be faced with neoprene?

Just a thought.........

Take care

You should be able to contact any supplier of abrasive belts and get just about any custom configuration you want. You will need to specify the grit, backing (cloth or paper), length, width and splice. They will even help you spec the grit and backing if they no your application and machine. There is typically a minimum order or a setup charge if it is an uncommon configuration but you may be surprised.

Contact a local woodworking or metalworking business to find out the names of their abrasive suppliers.

Hello OpMan,

I fully agree with your words. If you do not ask you will not find?! That is the truth.

So you 'waste' a couple of hours sending out emails, (which can be exactly the same other than the Addressee' name etc). I think most of us could afford that small price if it means being able to use 'our favourite machine'?

Well said sir.

Take care.
