Just wanted to draw your attention over to this site for a moment to get some opinions on what other people think of this idea.

Looks like a great solution for cleaning up edges on sheet material and, with a flat reference face already planed, I suppose you could even get a straight, ripple-free finish at 90º on a length of solid timber. Could be useful for someone in a small workshop with a small planer and decent table saw.

I've seen sanding disc attachments for saws before, where you use a staionary blade as if it were a disc sander, but this is very new to me. I certainly don't agree with trying to squeeze your fingers between blade and fence though - don't get me started on all that dust coming from the mitre saw either!

So, what does the forum make of this?

Quite impressed first off Olly.

A good idea in the table saw where the blade is cutting on the down stroke. Not so sure about the chop saw where the blade is cutting on the up stroke, surely there`s a chance if the wood snags, the timber & your hand could be pulled towards the blade.

Another though, could you not buy a 10"  self adhesive sanding disc, cut a hole in the centre & achieve the same thing.

Holy Nelly!

Where to start?

The increased friction from the sandpaper as the blade rises back out of the tablesaw will magnify kickback to mule like proportions. (especially without a riving knife or guard on the saw!!!!)

Applying force to one point on the side of a rotating blade!!! That's just nuts! Blades are designed to withstand tensional and compressional forces along their axis - not perpendicular to it. At best it will buckle the blade.

Pulling the work away from the fence on a mitre saw because you can't be bothered to adjust it correctly, leaving the workpiece unsupported and liable to go flying off in all directions.

Has this guy ever even heard of a push stick!

Goggles!

Hearing protection!

Mask! 

I have never seen quite such a magnificent display of blatant disregard for basic safety and common sense in favour of sloppy workshy laziness to promote a thoroughly pointless product in all my born days.

Cuts the worktime in half my AR53, cuts the worker in half more like! 

Besides, a good quality blade will give you a finish like that anyway!  

Rant over - normal service resumed.

I've always assumed that any chop saw/mitre saw (especially the deep-cutting sliders) carry that risk with a standard blade. The trick is to keep your left hand out of harm's way. Seriously, I think that's the main reason peope have accidents with these saws - they let they're hands get too close and probably try to bite off more than the saw can chew in one mouthful!

It does indeed look handy for cornicing, etc. Very tidy and perhaps also splinter-free. I imagine it's much easier than trying to trim something like that with a block plane or disc sander, where it's very difficult to keep the cut square.

I share the same thought on making your own disc though.
