Black & Decker Sander

[Kit Jackson]

I asked about this a month ago but didn't get any replies so I thought I might try again.

I've got Black & Decker No 88 sander. It's old but works well. It used to work well I should say The motor runs but the sander plate doesn't vibrate any more. I think the drive to the eccentric cam is slipping.

Does anybody know how to disassemble this please as I can't seem to find my way into it?

I used Google to find

One of the final pages of the manual is a pretty good exploded view of it.

It looks like there is a lot of dissasembly to get in there. Hint, phtograph or record the dissasembly so you can put it all back in order.

My old B&D sander died in a similar way. On mine, there was a plastic cam thing which had shattered. The plastic was very brittle.

Given the age ( I think I bought it in the early 1980s ), I didn?t even try finding a part.

Mine isn't a belt sander, it's more like a half sheet sander. The vibrating plate is 115mm x 230mm and I use 115mm rolls on it. The label says "No 88 Sander" and "cat no U-88". Thanks for looking though.

That may be bad news for me then. It's pretty heavy (4.5Kg) so I'd be a bit surprised if the critical part is plastic but the weight is just right for the large plate. How did you manage to get into yours? Does the plate come off the bottom? I can't see any sign of screws on top.

I expect it's too old to be able to find reliable drawings or parts... I looked at Miles Tool and Machinery, since they usually pretty good for B&D diagrams and parts, but could not see it:

However they do have loads of diagrams for other orbital sanders, so you may be able to find one that will give the info you need, even if its not for exactly the model you have.

(often the base is retained by a central nut under the foam pad)

As I recall, the screws were obvious but it was a at least 2 years back - long before Covid- and I don?t recall.

Thanks John, that's it. The base comes off first. All dismantled, a seized bearing under the oscillating part replaced and it's probably good for another 50 years service now.

That's a very useful site you've linked to as well.

Thanks again.

Chances are if it's old enough it could have been quite decent quality...
