Thanked: 2591Blade restoration using Dremel
I have been thinking for a while how to improve my technique with Dremel for more consistent results when restoring blades, and I found a convenient solution.
For my restorations I use a 1/2" sanding drum and I make my own sand paper sleeves as described here .
I found that using those short sanding sleeves leaves uneven scratch pattern that I just hated , I like things to be nice and even and symmetric.
I do not have a work shop so I needed to get my hands on a sanding drum that was 2-3" long and fits Dremel, well there is no such thing suitable for Dremel.
Today I was reading the Caswell buffing tutorial and I came with an idea that turned out great for solving my problem.
I made a sanding drum sleeve that can be used on my 1/2"x1/2" drum for working on a whole blade at once.
I started with packing tape and sand paper (220/320/400/600/1500)
and made the sanding sleeves:
I cut the sleeves roughly 2-2.5" long.
The trick to ensure that the sleeve will not bend/tear on the sand drum is to use 2 layers of tape under the sand paper. The tape is sturdy enough to hold well and not come apart.
After the 1500 sand paper
After some buffing with Maas
All 4 razors were done in ~3 hours.
Now I'll run the razors in a Tumbler with corn cob media to see how the finish turns out.Stefan

Great idea. I wouldn't have believed it worked without seeing the result pictures. I'll definately look for a suitable rod or tube.
Is there any deformation of the sleeve where it's over the drum bit?
Perhaps a sleeve with a bigger diameter and custom drum would work better although I would already be happy if I get this to work

Thanked: 10This is a great method. However I experienced difficulty sourcing a metal or plastic rod of appropriate diameter. I had the idea of using a wooden rod so after a little searching around I found a suitable diameter of cane (which has a smooth surface) from the greenhouse and I cut the cane down to a suitable length. This works very well with the advantage that the inner sticky tape (with its smooth side in) can be secured with a pin so that its tendency to slip along the rod can be overcome when winding the tape down the rod.

What do you use for a mandrel for wrapping the tape/sandpaper?
