240v Flat Bed Linishers
FASTdan - 14/6/11 at 04:54 PM

Can anyone suggest a decent one? All I can seem to find is the small 'clark' types attached to a grinding wheel. I'm after something with a bed at least 400mm long and ideally 6" wide (ie the standard 900ish long belts).

A 2nd hand industrial one would be nice but of course there's the whole 3ph problem to overcome with those.

I use a Machine Mart Disc/Belt sander for metal. It's good and has lasted years.

hmmm good call - not sure how I've missed that one! seems to fit the bill - whats the length of the flat area of the belt? presumably somewhere in the 400mm region?

Please note that it's for wood, plastic and non-ferrous metal.

This implies that it's unsuitable for steel (probably because it can't deal with the hot sparks).

ah that could be why i've dismissed it in the past - however it would be for alu use, although its the usual case of 'you say that now' and in 6 months time you need another to do ferrous.

I've not quite got my head around what separates the wood ones from the steel? aside from perhaps the overall 'sturdiness'? How does a belt sander need 'deal' with hot sparks?

Belt sanders designed for steel are designed to direct the sparks to somewhere where they won't do any harm - usually some form of cup or bucket just below where the belt goes round the spindle. Also, everything is just that much more solid, and able to take the extra 'push' and heat from grinding steel.

Also, on a more practical note, they have some sort of solid fence or rest to support the work - tougher than you'd need for lesser materials.

Is this the sort of thing??

I've had a few good tools from g and m.

That's certainly an industrial-sized beast! It doesn't say whether it's for wood or metal, except that the word 'linisher' strongly implies that it's for metalworking (if it was for wood then it would be called a 'belt sander' ). Almost certainl for any material, but best to confirm with G&M if it takes your fancy...

And don't do what a friend of mine allegedly did... spent the morning sanding some wood, then did some steel linishing in the afternoon - without emptying the dust collection box. Got through a couple of fire extinguishers, apparently...

I guess its a metal one, as they hve different ones in the 'woodworking' section!

I use it on steel too, it's OK, don't apply too much pressure and the belts and discs last, and the disc is brilliant for finishing angles.

I also use a similar one, and its fine (even deburring steel) as long as you dont lean on it too hard, which can stall the motor.

Use it at least weekly, and have had no trouble, except having to replace the switch once and "dedust" it internally ocassionally.

Cheers
