B & D 10" Grinder score!

[Ststephen7]

I just got home with this old Black and Decker 10" Grinder. I will do some future welding work for it, so... score! He


It has large glass shields intact, along with lighting. It also has the cup holders and cups! Seems like it's all there!

It is 3 phase, so I'll have to get a VFD if I want to keep it... pretty sure I do.

I may be asking for wiring help after it's all cleaned up and repainted, and I have a VFD in hand. If you have suggestions for the right inexpensive VFD I'm happy to listen.

Nice snag on the grinder. I have an older one in very similar condition. I was told mine came from a Baltimore Shipyard.

I asked if he got these at an auction, since he had 4 big old grinders, a surface grinder, and a small shaper.... he said an older guy he knew was downsizing and these were all in his storage space.

He walked me around his 2 garages... He has a ton of neat tools and stuff; about 12 anvils, 2 well over 300 lbs, and about 20 nice vises, ranging from 3.5" to 7"! Most of the vises were in whatever condition he acquired them, and everything stored in unheated spaces or just outside. If I go back I'll take some pictures...

Teco L510-101-H1-U (affordable, easy to use, excellent documentation)

Whatever you do, avoid the no name VFD's from Ebay. The sparse documentation (written in Chinklish) will drive you nuts.

Here is mine.

That's a beauty!

Here is a pic of some of the parts, semi clean and on the healing bench ; )

I am thinking I want a mix of painted and bare metal parts... not sure yet though.

It might be a while before I get it running... I'm not in a position to buy a vfd at the moment. So I'll keep working at getting it cleaned up and repainted.

A lot of parts I expected to be cast iron are cast aluminum.

And... might these brass cups have been OEM? They are heavy as hell...

Oh yeah... I found a mercury switch (maybe 1.25" long, 5/8" dia) in each light housing, with quite a bit of mercury in each. Am I good just throwing them back in place when reassembling? They seem sealed up tight...

Interesting and thanks for sharing.

I've got a slightly later version of that one which is 3/4hp 110-volt-only; rare to see a larger motor which isn't also capable of 220-volt power.

Mine has shop-made guards, so interesting to see what the original equipment looked like.

Mine is 1hp and 110 only as well.

The tag does state 220/440, however it is 3 phase... When I get to reassembly I will be asking for help determining it's current (Ha!) set up, and to be sure I'm configuring it for 220 and not 440.

 

[Ststephen7]

What colors are yours? I'll be repainting, and not sure if I want to stick with the grey...

You won't kill that one

Seems like an ok choice. However, it is fan cooled, so you'll probably want to put it remotely. If you want to mount it to the grinder, you'll want a VFD in a NEMA enclosure.

Has anyone replaced the bearings on these? Mine feel really rough, like they have detents... So... I opened up the enclosure to get them out.

I found the same bearing (87504) in both sides, however... the 2 sides were set up differently.

The right side has 2 preload washer thingys under the bearing, and nothing holding the bearing in place.

The left side had nothing under the bearing, however it had a large washer holding it in place.

My first thought was at some time the bearings were replaced, and the washer was left out of one side, and the preload things were left out of the other side. However...

The cast ribs inside the left housing had been ground (lathed?) away to make room for this washer. The right side had the same tapped screw holes (for the washer) however the ribs have not been touched, so the washer will not sit down on top of the bearing.

Why would there be this difference?

It's hard to believe this would be due to shoddy assembly procedures, and... There have always been lazy/distracted/drunk workers.

Could these things have been added at a later date?

I can make a washer, and reassemble with one spring under each bearing if that's what I should do... For now I'll find and order the bearings.

Personally, I would simply cut the notches out of an appropriately sized washer.

Yes, if I had a washer that big.

It's a little over 2.5" OD, and 1.5 ID x 3/16 thick (thickness is not critical)... I thought I'd have to make one because I have no idea where to get a washer that big... I don't have one, just some 1/8" scrap I can use.

Should I put one preload thingy under each... Why would there be 2 under one side and zero under the other, other than carelessness?

I'd think so. You know FOR SURE it's been apart so I'd make sure it's put back together correctly.

Re: B & D 10" Grinder score! Sneak Peek...

Anyone up for a sneak peek at my grinder restore?

As soon as I got this thing home I made up my mind that I was NOT going to do another grey grinder. I love this Hammerite dark blue paint, and once I stripped the pain off the motor housing and saw the bare aluminum I knew what I was going to do.

I'm not done with the lights. I plan on wiring it with an additional 110 line just to power the light, as I wanted to put really bright LED appliance bulbs in there, and 110 seems the only way to do that. I also have myself a diagram and the wiring to return it to the way I found it... regular appliance bulbs run off the 3 phase power.

The lights work off mercury switches in the housings, and go on/off as the glass shields are tilted down/up.

I cleaned up and made new buttons for the main power switch on the front.

It is sitting on a cheap pedestal. I'm still working on the one it came on (probably not original).

Well... here it is... What do you think? OH... and please ignore my filthy basement shop. I have a ton of projects going at the same time...

She's a beaut! I hope mine is aluminum under all that Navy gray!
