Thread: Custom flap wheels... really.

I was searching for high grit flap wheels for the Dremel. The highest I could find was 400 and from what I have read here that is the highest anyone has found.

Well, I got to reading this blog or something of someone who like to do small woodworking (model building or something). And this person uses a split mandrel where you can slip in whatever grit sandpaper you want and have your very own custom, two flap, flap wheel.


A Google seach led me to this place...

I already put in my order.

The writer goes on to say that 1/8 rubber dental retention rings available over the counter at any pharmacy will do a great job of holding the paper in place. I will report on how it works.

I was thinking about trying, and just hadn't had the time, to make flap wheels. it looks like if I cut up the paper I could make a form and lay it in there and press in epoxy through the core to bond it. looks like most of the flap wheels I get are only that.

this looks a lot easier, let us know how it works out. I'm guessing if the speed were run high it would help compensate for the fewer flaps.

Cool idea. I can visualize slipping a strip of paper in the slot of the mandrel; I can't visualize how you'd then secure it with a small rubber band and allow for it to flap.

When I get home tonight from work I am going to take a pic of what I use for "Power" sanding hollow grinds.... After you get done laughing hysterically you will probably say "Holy Moly Batman" that could work, and it sure is a cheap solution....

Glen where is the post you promised

Greasless compounds can be applied to the buff of your choice to make custom sanding wheels. I think this stuff is really underutilized.

Do a group buy, a little goes a long way.

My friend, Doc Molenaar, and me have used the greasless compounds on knives for the past 2 years. They work very well. They are water based so the steel cleans up easily, no wax or grease. Follow the instructions to build up the initial "head" and then apply more while using the buff.
Always keep the tubes sealed or the water evaporates and the compound gets hard. To restore moisture just set the open end on a water soaked paper towel.

I am not sure what the policy is about linking to other forums but there is some good pertinent information here. This is the way I make my coarse buffs.

Hi gents,

Sorry for bringing this up, but I'm curious about what these split mandrels can do. Just like Chris L, I'm guessing the we start by putting the sand paper in the slot and then we wrap the mandrel around with the sand paper and then what?
I'm sorry, but I'm not visualizing how can we "dress" the dremel with sand paper to look (and work) like a sanding drum or flap wheel.

Thanks for any additional help.

stuff the slot with strips of sandpaper... the rubber band goes on the mandrel right above the sandpaper, then slide it down just until it's pressing on the paper strips. this will keep the paper from falling out of the slot. you end up with a basic flap wheel.
