Sanding Machines for Scale Modeling video now up ...


Recommended Posts

Paul is dead on about the MicroMark 5 inch disk sander.  It is the one that I have

and it is noisy and the RPM are too high.  I slow it down a bit with an old Dremel

Solid State speed control - from before Dremel rotary machines had on board speed

controls - but the loss of torque follows a curve function instead of a straight line so

it does not slow down all that much.  I only work with wood so the speed is acceptable.

It does run true though.

One addition I made was to use cardboard from a box to enclose all three sides of the underside of the table and

behind the disk and insert a crevice tool thru a slot to vac the copious dust produced.

A simple port under the table is not as efficient.

 

I also agree about the tilt function for a spindle sander being an essentially useless feature.

Frame bevels follow a continuous change and free hand is about the only way to shape them.

I can see no utility for the up/down oscillation function though.

 

Harbor Freight has a 4 inch belt sander (I ignore the disk part)  back on sale for $60 - but

Paul is also correct about real estate needed and it being useless for inside curves. With 60 grit

medium - it will eat thru wood fairly fast.

 

The combo sander with a 1 inch belt and disk  would be of questionable utility if it were $10.
