Not much of a jig really – but if you cut your own paper for a drum sander you will know what a pain it is….......well not anymore my friends…...

The trick here is to have a reference surface as long as the paper – in my case, my combo Miter Saw bench thing filled the bill. A scrap of masonite is used for the cutting jig – some Sharpie marks show where to place the straightedge for the cut.

The rolls of sandpaper (4 grits) hang in the rafters behind the jig – select a girt and pull to the end of the bench – clamp and cut. Repeat if necessary. Pic. 3 shows the paper looped behind the drum sander so you get an idea of where the paper is hanging in the ceiling….....

The end of one cut is the beginning of the next – so you only need to make a starter cut (labeled on the jig as “start cut here”) once per roll. The other marks on the jig just show where to line it up the bench….

Sorry in advance to all of you who are offended by the post with a piece of masonite with Sharpie marker on it…......but it’s a real time saver and I have a chance to win 10,000 :)......you understand.

Thanks for looking…..

I see,

Drum sander solves a lot of problems,

but creates new ones !!

Hope the jig solves them all, including the prize.

Well I’ll be. There’s a jig for that.

Watching me make my strips is not for the feint of heart. I need something like this.

Appreciate the comments!

David – well stated – thanks!

Fernando – prior to the jig – would have to wait for exotic humans to show up and help with the paper cutting – and that was never a had a positive outcome…...:(

Eddie – if anyone could have the old sander – it would be you…....except it’s built into the “the wall” now, so not sure it’s going anywhere, even if I win the 10,000…..........but we shall see…..

Steve – finally someone who understands the problem! Thanks.

Gerry - just copied the original strip that came with the sander – mines a Performax 22” so I assume the angle is unique to that machine. If you have the same sander – I’ll try to measure for you…..let me know.

I would dare to say a drum sander erases problems, and any way you can save some money to refit your tool with fresh paper is a very good idea.
Great jig Jeff, you have my vote.

Jeff, now Gerry put us against the wall.

Is an additional contest.

1. How we do find the cut angle,

2.You cut the angle on one side, but then need to cut the angle on the other side. Then, how long the sanding paper need to be?

That will depend on the diameter of the sander cylinder, the length of the cylinder, and the width of the sanding paper. Am I right? Even if you have the previous sanding band broken, and you want to change grits to a wider, o narrower belt, you need to change both, the angle and the length.

We have until tomorrow, 8AM Arizona time (Is that central time?) to come with a solution.

Thanks Marty Roger and Dave…...funny…

Fernando – you may need to fire up the paper sketch-up program for this one cause mine is broken…...I do know this much – if I don’t use 3” wide paper – the math doesn’t work out. I had a bunch of 4” paper and you can’t get it to end in the right spot.

So you are right – but my advice is this….....ALWAYS save one old worn out original strip…... :)

Fernando – forgot to ask, why do we have to figure this out by 8AM Arizona time? I’m in central time, but AZ is mountain time…..

Jeff

Let me think about your 4” wide paper. I cannot imagine why you can’t get it to end in the right spot.

why do we have to figure this out by 8AM Arizona time?

Just because Gerry happens to be there.

Fernando – you do the math and I will make the test cuts and post the results….....if you can make the 4” paper work – you get the 10,000 (of course in the unlikely event that I win).......

Good one…

Hi Jeff,
We need the diameter (or radius) of your drum for initial calculation, which my eldest son already figured it out. . Then, we need to know how large it is the side of the drum which will be covered with paper.

10,000 beers? what´s that?
