Project Information

I posted the sanding sleeves and how I make them a while ago but never posted how to make the pattern so I thought I better .


I start with measuring the diameter of
the sleeve drum and then multiply that by 3.14 which gives me the circumference and the length of the angle cut .

Here is a calculation to determine the length of the side length of the pattern .
Simply multiply 3.14 by the height of the drum which is 4.5" and that would give me the length of the side of the pattern but I prefer to mark it of the drum itself .

I cut a strip of poster board to width in this case 2" wide ,the same width as the original sleeve wrap size .

Here I laid out the angle for the end of the pattern which is 6.28 " so 6 1/4" will work fine





Next I wrap the pattern around the hub starting at the top with the patterns angle cut upward along the rim of the drum and once one complete wrap is done I secure the pattern with a bit of tape then I finish the wrap end mark the bottom along the end of the drum .

Now I cut the other end of the pattern by using the same angle as the other end .
This can be done by using a bevel gauge and aligning it with the mark I made at the bottom of the drum as I do here or by measurement along each side of the pattern
!

Now its time to cut the sand paper strip ( I am using a scrap piece here )using the pattern and a straight edge .


Next is the tape along the edge that will hold the sleeve together and wrapping the paper tight around the drum and all done .
I hope this helps and I was clear enough explaining it .

Good one Klaus.
I think if you live long enough you may end up in a shop with nothing but shop-made tools.
The careful observer can always see a few in each of your posts.
This is a great little way to economize in an area where overpricing is the norm.
Thanks!

You are making this easier and easier for us. Thanks for all the info Klaus. I also do not believe in the price of these we have to pay. Especially with all the different grits.

Thanks for all the comments and it' nice to see you find some use for this .
Paul if you and all the others would stop posting all those nifty shop made tools there may be a chance but I am having too much fun making my own and besides they are the right price and size .
BTW that little bevel gauge gets a lot of use as you can see and that straight edge that you came up with is certainly a finger saver haven't had a cut in my fingers since .
