Shopsmith Forums

All,

I bought a used model 510 several months ago and I'm just now needing to use the sanding disc. It mounts to the main spindle just fine. However, with the lower saw guard in place, you cannot push the disc all the way on to the drive spindle because the guard blocks that from happening.

This does appear to be a model 510 lower saw guard (I've looked at the pictures of both the 500 and 510 guards and confirmed mine is the 510).

I would like to use the lower saw guard for dust collection but so far I'm frustrated.

The only thing I can think of is that the sanding disc hub is too short?

What could I be missing here?

Thanks.

You are missing the update sanding hub you need to use the sanding disk with the 510 system.

When I upgrade my 500 to a 520 shopsmith provide one updated hub and I had to buy the extras to update the rest of my sanding disks.

I have the part number here somewhere but in case I can't find it you can always call shopsmith and they can look it up for you. BTW I think they were in the $17 or $18 range at the time so it is not so cheap to do.

Unless someone else can verify this you should most likely call shopsmith and check to see if this is the correct number (514493) and also make sure it comes with the 4 replacement screws (sometimes the originals come out easy and some times they don't, two of the 5 disks I did I ended up drilling out while 3 of them just unscrewed...) The screws can be identified by the blue dot of thread lock.

Also the price seems to have gone up, $23.40 now.

If I'm going to be spending $23.40 to make the sanding disc work with the lower blade guard, I have to ask: Does the lower blade guard with a shop vac attached do a good job of dust collection?

The lower saw guard, attached to the dust collector, pretty well stops the sanding dust from flying upward from the back of the disk.

Of course, you can always opt for a dust mask and goggles. Over time the cost will be the same, but the risk to health greater.

This is a difficult question to answer directly. To ask about a ShopVac. There are many and they are not all equally good as "dust collectors". As stated already, the system works well if a DC3300 is used. I have a ShopVac as well, but I do not use it as a dust collector on the Mark V, in any mode. It does not do the same job as does the dust collector. The differences being in volume of air moved. The dust collector moves more air thus more dust.

My DC3300 works great at keeping the saw dust at a minimum while using the disc sander. It works best with the lower guard adjusted to clear the sanding disc by about 1/2 to 3/4 of an inch. To loose and the pull on the dust is reduced by the free space, to tight and some of the dust doesn't make it into the lower guard.

I have not tried it with a shop vac, so I can't comment on that, but I suspect it would somewhat depend on the characteristics of the particular shop vac being used. Higher volume would probably be better.
