I'm thinking of getting a Proxxon TG250 disc sander for squaring off parts etc but would be grateful to know whether you can use the whole face, given that one side will be going up and the other going down ?

Re: Disk sander
Hello Adrian, I looked up which sander you mean. I don't have it, but product looks nice, but strange they don't mention e-power rating of it on website.
First I thought your question was the wear/tear of the sandpaper and I thought; 'of course will be same everywhere', bcs what goes up will come down. Bcs it goes round
But you mean using it simultaneous of course.
I think, if the e-motor is powerful enough to overcome the friction of the whole surface of the part you press against it, than why not. Up and downwards doesn't matter. Maybe the sanding by middle part of disc will result in little less sanding bcs of speed diff inwards and outwards of disc.
But normally you don't fixate while sanding, you stroke the part along the disc by hand (and after sanding for a while flip your piece over), so the surface you sand end up equally smooth everywhere, right!?
Looking at pic, the black protection cover (small strip over top of sanding disc) is sticking/protruding in front of the disc, so that should be removed otherwise you can't stroke your part freely enough (for what you want, I guess).
Btw,
Happy New Year, Everyone!

Re: Disk sander
The question about power is a good one, as one of the reviews on Amazon said that he could stall it sanding balsa wood, and I want to use it for aluminium and brass !
The Proxxon brochure says it can be used with non-ferrous metals, as well as steel, so I wonder if he just had a dodgy motor ?
I note quite a few of these machines have a guard over the upwards moving part of the disc, but others show the whole disc being used.

Re: Disk sander
Hi Adrian
You can sand across the whole face on these type of sanders.To be honest though you are better sticking to the downward side.Sanding on the upward side will obviously try to lift your work off the guide table.In short, small pieces sand on downward side.Big pieces that you can hold firmly can carefully be sanded across the face.
