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 https://s3.amazonaws.com/vs-lumberjocks.com/nr2yy8q.jpg!
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 .
