Show and Tell: Manual Disk Sander for Modelmaking

We check out a mini disk sander designed for scale modelmaking, which separates itself from other small disk sanders by being manually crank powered. Ultimation's Sander may be ideal for precision sanding work that doesn't need high RPM speeds, and Norm uses it to clean up the excess flash of a small resin model kit.

That's nuts. At that point just use your hand and sand paper. That's more than a brand new powered disc sander. Absolutely insane

[ewe]

I was drawn to this video because I could see this being extremely useful in building kumiko panels ... but now for $225. Wow. That's crazy. I'll now take this idea and build one myself using a 3D printer.

[fieromike]

I got one of these as a gift for Father’s Day. Clamp it down to the table and it’s much easier to use.

[Preske]

This is a $225 solution for a problem that didn't need a solution. There is no way you can convince me this is more precise than a regular handsander.

[roundcube]

Both of those mini-sanders are bare bones in the way that would make your life more difficult, yet are priced as though they have gone through many iterations trying to min/max profits over usability.

I feel that if the motorized sander had a voltage controller we wouldn't be sitting here looking at an advertisement disguised as a show and tell.

[martymischke]

$225 seems pricy for a crank tool. I'll stick with the manual sanding board methods.

[ryleegriffin.]

This would get a lot of use in my shop. I am curious though, what justifies it being priced equally if not more than most motorized tabletop disc sanders?

[urban_radagast]

I think something like this that's pedal powered could be really useful

[joshveer]

I think this COULD be alot cooler, it should be geared WAY higher than 1:1, should have some kind of method of securing itself to a surface like a clamp or really strong suction cup, and maybe a different power method like a pedal or something.

Code name colossus is such a wonderful blast of nostalgia

[backpacker]

As soon as I saw the title, I knew I was going to get one. How amazing!!!! The powered ones are so OP for modeling styrene parts, but using hand tools is impossible to get a truly straight even result. Even if straight, trying to get a square edge is unlikely.

[coffeeshangarworkshop]

It seems like the manual one should have a flywheel so that it will stay at speed for a minute if you Crank It Up. It would be as precise as the RPM you crank it up to, and as it slows down it will become more precise. It would also let you use both hands 🙌 on your material.

[brucelee]

Clamp it to the workbench, it will be much easier to use while still being easy to move around. One of my Grandfathers made a chain drive grinder back in the 1950's using a cheap hardware store hand grinder and the foot pedal drive from a defunct pushbike - bolted the crank bracket to the leg of his bench with only one pedal (the one connected to the large sprocket wheel), replaced the crank handle with a small sprocket and used the bike chain to connect them. Worked well, it would run as slow or fast as you could pedal.

[FormerlyKnownAsAndrew]

Oh man, this is pretty cool.
Definitely wouldn't buy for 225USD. But the idea is neat. I like that mitre gauge.

[JessHull]

I don't understand how that manual disc sander can cost 225 dollars?! I want one for a very specific reason but at that price I can just make my own...

[adrianpintea]

The manual one looks like it would be great if you have projects with your children. They turn the thing and learn while you do the difficult things, or vice-versa.

[longdarkrideatnight]

Looks like it is intended to be clamped in place, It would be good to see what it is like when your not trying to hold it still hold the work, and turn the crank.

[Warshipmodelsunderway]

I posted a response on the Facebook Tested page of the hand crank sander I use for precision work, which I converted from a Picture framing sander.

For power sanding Proxxon makes a great pair; the TG 125/E, and the TSG 250/E. Both are variable speed, so you can slow them down to 1150 and 820 RPM respectively without the loss of power you get when trying to slow down other hobby power sanders.

[aserta]

This is basically a piston ring grinder, which is funny... because i actually use for exactly this purpose. Found it in the junk yard, German made used to grind the piston rings on big, big engines. As such it has a 20x20 cm wide table meant to support the bigger ring with a tiny little manual grinder on the side.

I use a dremel mounted in a vice - has speed regulation and you get good control
