let's see your craftsman block grinders

[alpinewhite]

So i was the one who grabbed the 1hp grinder in long island.(posted a few pages back) so glad i made the trip out there. The grinder was never used. Still brand new. Not a scratch on it. Money very well spent. Anyways i was just wondering if anyone knows whats involved with converting it to 230v. I know it might not make much of a power difference but i have a buddy who is an electrician and is happy to do the job for me. Is it just a matter of changing the plug or is that a stupid question. Thanks in advance for your help.

Mine had a schematic inside the bottom cover. I also found schematics that TM drew up. It involves moving about 3 connectors. Basically, the field winding and armature are in series in a 220v setup vs. being in parallel in a 110v setup. That's how my 3/4HP is. I'm assuming it'd be the same on a 1HP.

Thanks alpine. I havent even had a chance to mess with it much. I didnt even think to look under that cover. Ill try to look tonight. Thanks again.

See if there is a bottom cover plate on the grinder. You will have to remove the grinder from the base/quench tray first.

If there is a bottom cover, the dual-voltage models often have a wiring drawing on the inside, showing the dual voltage options.

If you do not have the drawing, one can be found in my signature line link.

 

[meatsis]

Awesome thanks guys. Torqueman does it make any real difference in the way it performs. To be honest its a beast already.

 

[Outlawmws]

You will also need to change the plug out for a 220 plug (I use twist locks), and have a 220 outlet rated for the job. (not your dryer plug...)

If you trace this schematic, you will see that closing the switch will send power to the orange and yellow wire which are for the field winding (stator). In addition, power goes to the relay on pin 4. Upon pin 4 getting energized, it sends power to pin 2 for a few seconds to energize the "start" winding (orange wire). As you can see, a capacitor is in series to correct the power factor. Pin 3 gets energized as long as there is power on pin 4. Pin 3 goes to the "run" winding of the motor (brown wire).

On a 220v setup, pin 4 gets power from the orange wire from the stator. By this time, the voltage should be down to 110v because the stator is now in series with the "run" winding. 110v now powers pin 4 of the relay and the rest is the same as it did on the 110v setup.

Is this one worth going after? He's asking $75.

Yeah, the closest one to you looks to be in Shiremanstown.

I haven't run one on anything but 115 VAC.

But there's a recent discussion about this very topic a few posts ago.

That's one place I have been meaning to visit, guess there's no point,

It depends upon condition. It looks nice, but I'd top out at ~$50 if the rest of it was complete and in very good condition.

For $75, I want a NIB 1/3-HP round top.

But I have more 1/3-HP Blocks than any other grinder.

LOL! They were fairly common 2/3 years ago when I snagged my 1/3 and 1/2, but been hunting for a 3/4 and haven't seen ANY block listed since Thanksgiving.

Same here. I just checked the Cleveland CL and nothing. Since it's getting a little warmer, I stuck my head outside and heard a giant sucking sound coming from northwest of here. I think that's TM's block vacuum!

It is an industrial rated grinder, but I agree. Asked him if he was firm on his price and haven't heard back yet. No light or tray make for less to part out too. Heading out in the morning so he doesn't have much time to get back to me.

Wasn't the Torqueman, really!

Here's what followed me home earlier this week.

An 8" Baldor (3/4-HP ?), with lighted eye shields.

More, here.

There are two still on Craigslist in central NJ:

He said he was firm at $75, so I wished him good luck.

I'm going to NJ tomorrow and I'm tempted to pick up the 1/2 HP. But I think I have enough for now.

Here is one in NJ worth $75. With a stand

Ok, I hate to do this but new to the game I need to know if this is worth $125? Grinder and stand.

Not a chance. That's one of them thar Block-like Objects on a decent stand. The value would be in the stand, not the grinder. $50 tops for me but I'd be more in the $35 range, only because of the stand. The grinder would go to the recycler.

I concur.

I wold pass on that, I wouldn't have much faith in that grinder or would bother with one from that era plus the stand is vey similar to what were available at Northern Tool and Harbor Freight for around $40. I know because I have one, there actually not bad except they're stamped made in China on the front.

 

[alpinewhite]

I found a 1HP that needs TLC. No stand. No quench tray. Just the built-in eye shields. $120. Sounds a bit high, right?

It's hard to say about the grinder. Some of that 'post-Block' style grinder may in fact be OK (ie: 1-HP), while others are definitely NOT. [See following link: http://www.garagejournal.com/forum/showthread.php?t=274725 ]

I'd be a buyer of the grinder @ $25, just to investigate it's inner workings.

The stand is substantial, if it is like the one that came with a Baldor grinder I have. It has heavy duty cast base, water tray/tool tray, and mounting plate.

I wish I could recall where I saw them for sale, new.

I wold buy it for $75, but I have a 3/4-HP? 8" Baldor looking for a stand.

The diamond wheel raises the value, but I think the price is high due to the condition. Still, 1hp grinders don't come up often so that might factor into your decision. If it runs well, then the outside should be easy to clean up. See if you can get him down in the $75+ range if the bearings don't need to be replaced.

$125 for a 1-HP without the base with tool rests & quench tray is too high.

The large q-tray is available, but this model came with base with tool rests & quench tray.
Note: the center band's knock-out is still in place for the q-tray, and probably the wheel guards are not drilled & tapped for the grinder mounted tool rests, like other Blocks.

The base with tool rests & quench tray is very hard to find separately; not to mention the tool rests.

I would be a buyer @ $75 and part it out, or convert it to a stand-alone w/o the base with tool rests & quench tray.

I think I got lucky and found one of these on ebay on accident it was only $25 to my door so I jumped on it. It was not listed as a craftsman but I found some pictures and I am pretty sure it is a craftsman. It fits on my craftsman stand perfectly but I have not been able to line all the holes up on a round top or flat top. Monday I have a pre block coming in. I will post pictures this weekend if I remember and see if you guys think it is a craftsman. The holes for the rest have been sealed up. not well either will grind them smooth before paint.

GRINDER MODEL 257.192150.
IT IS ON A SEARS INDUSTRIAL TOOL STAND MODEL 351.19210

The stand is what was attracting me to it.

 

[Rickenbackerman]

Did anybody notice this light on ebay?

Sure would be nice if there was whole warehouse full of these somewhere...

That looks like the 6-inch grinder on the Wisconsin border that's been for sale for several months. Worth about $50-60 to the right buyer...

I would say it's only good for the cover and maybe the socket. The flex arm is black and that's not what I have seen in block grinders.

 

[Outlawmws]

FYI for those trying to rig a light, with a goose neck, I was in a music store last week and it looked like a mic flex goose neck would be semi easy to adapt to use for a light goose neck. No, not factory, bit not everyone needs 100% stock parts.

The mic goose neck was 18" long BTW.

 

[bagged89s10]

I'm going to try to use one of these. The reflector is about twice as wide. I'm going to paint it hammered black and see how it looks. If it doesn't work or look good, I will mount it on my drill press or workbench.

Doesn't look bad. Only issue imo is it has a patina and grinder looks brand new.

[drivesitfar]

Bagged: i like the light because it probably actually puts more light on your work are than the little ones the blocks come with originally. i agree with SS that you either need to paint it or i'd shine it like McB did on his for his Blockmeister for a steel or brass look.

ALL: i'm going to part out my 1/3 HP block in case any of you need a water tray, light, eye shields and maybe the block grinder too because i don't use those extras. PM me if you need them and i'll post pictures of the block in the classifieds. just a note not Ebay pricing, but not YS deal either.
