let's see your craftsman block grinders

[linwood]

Thank you, appreciate it!

 

[McBrownie]

Does anyone have a chart or something that gives the block HP sizes for the types of work that can be performed on it? Obviously why get more HP than you need but under sizing is even worse.

Mr One Eye,

If you think about it in terms of Surface Feet per Minute (sfpm), an 8" wheel has a 25% higher sfpm than a 6" wheel. So, in other words, you can get 25% more work done in the same amount of time. And, it takes a bigger motor to swing the bigger wheel. My guess is that a 1/3hp and a 1hp would do about the same amount of work with 6" wheels. However, you would struggle bogging down the 1hp.

If you want to add a belt grinder you need a 1/2hp cap start or bigger according to the manufacturers. I have a 3/4hp cap start with a belt grinding attachment and it never bogs down. TM (Doc) has a 1hp and says it is a handful. Sounds like a truly industrial machine.

For a homeowner, any of the old block grinders will do fine. However, if your man-card has not expired, it is fun having one of the big boys.

 

[McBrownie]

Here's mine, before and after, bought it at an auction. Love it, I mounted it on my bench and here's the crazy part.... I won't use it for wire brushing rusty stuff, I still use my old Black and Decker for that. Don't want to mess up my paint job. It's a 1/3 HP I guess when I find it's big brother maybe I will.

Also, new to GJ, and amazed by what everybody does and all the knowledge.

Congratulations Linwood and welcome to GJ. If you want, adding a gooseneck lamp to your grinder is an easy upgrade.

Linwood don't feel bad about not using it, I have 2 that I redone last year that I haven't even plugged in because I don't want to dirty them up .....

 

[linwood]

Hey thanks guys, and thanks McBrownie, that would be sweet.

yep crazy, the wife says I'm nuts for having two, but it's not as bad as the **** I catch for the other stuff. I'm watching out for the 1/2 and the 1 hp, give her more reasons to roll her eyes.

working on a Stanley Handyman now, kinda giving me some troubles, I'll throw up another thread see if I can find some parts or answers.

thanks again, would have never done it if I hadn't seen yours.

 

[vertguy]

Nice refurb Linwood... just be careful as these blocks have a tendency to multiply. I went from 1 to 4 in a matter of 6 months (don't tell my wife - hehe). Still not sure why I need them all, but I am sure they will either get put into use or gifted to one of our sons.

Mine are all in good, original condition. But every time I see one like your after a new paint job makes me want to start tearing them down.

 

[linwood]

Vertguy I know what you mean about keeping them OG, I wouldn't either, mine was in bad shape. I like to tinker, makes you feel like you rescued a puppy or something when you redo one tho. haha

Tore down a "rescued" Cman table saw tonite. Don't need it but cound'nt see it go for scrap.

 

[CalsXS2]

Anyone have a lamp shade for around a 1978 model. Give or take. Both the plastic and metal part.

Or has anyone come up with a good substitution.

That link is for the plastic cover only. Unfortunately, the metal shield is no longer available.
You would need to make one, or find a donor lamp.

Beautiful paint---what brand/color did you use?

 

[exmaxima1]

Mr One Eye,

If you think about it in terms of Surface Feet per Minute (sfpm), an 8" wheel has a 25% higher sfpm than a 6" wheel. So, in other words, you can get 25% more work done in the same amount of time. And, it takes a bigger motor to swing the bigger wheel. My guess is that a 1/3hp and a 1hp would do the same about the same amount of work with 6" wheels. However, you would struggle bogging down the 1hp.

You should also consider what you are grinding. From what I've read, a 6-inch wheel at 3600rpm is an ideal combination for carbon steel, and increasing sfpm reduces efficiency. Stainless steel wants slower speeds, and wire wheels want more. I've owned a number of grinders, and like 6 or 7 inch wheels (vs 8") at 3600rpm. But, of course, once you convert to belt.....you never go back.

Craftsman, as well as other makes use these on newer grinders.

BTW - How did you make out in the search for wheel guard covers? What model number Block?

I wasn't going to post my grief about this. But since you asked,,,,lol.

Some SOB beat me out of that one. Offered the guy more money I guess. I tried to pay the guy to hold it. Or come get it right then and there. He said no, wait until the week end. He promised he wouldn't sell it.

Now he sent me a message saying it's sold. And now he won't respond.

No integrity I guess. I know money talks. But I feel he should have at least told me he had a better offer and give me a chance. Oh well. I'm over it.

That's the second time I've been beat out of one like that. I'm starting to think it's not meant for me to have one,,,lol.

Now here's where I might be a fool.

I found a nice 3/4 hp model 397.19350. IIRC that's the same as the maroon one you have. But it's very far away. I talked to the guy a long time on the phone. Seemed really nice and legit. My initial thoughts were I have a son that is a truck driver and is in that area every so often. I could have him pick it up.

Here's the foolish part. The guy said he would be in my area in the middle of March and he could bring it. He even drew up a legal looking document assuring me he wouldn't sell it once he received payment, and he would pull the ad. Maybe I'm a fool. Time will tell.

So I'll have it in March or sooner,,,lol.

He said it was his Dads and was used for buffing. So it's got buffing compound all over it and needs a good bath. I think it will clean up though.

 

[drivesitfar]

Cal: where are you located. i've got a complete 1/3 HP i could sell that looks better than that if you can pick it up. PM me for details

Thanks for the offer. But it's a done deal.

This one was used as a buffer so it's got buffing compound all over it. It should clean up I hope.

 

[bczygan]

There's either a 1/3 or 1/2 HP for sale south of Akron for $35.

It's hard to tell, but it looks like a 3/4-HP, and with the rear exhaust I'd guess it is a dual-voltage guy.

I think you have done well!

The eye shield can be glued with a little care, all the hard to find pieces are there!



BTW - I have 2 replacement drop light bulb shields on order. I want to see if they can easily be modified to use with the CM plastic light covers.

 

[vertguy]

CalsXS2 - I have the same block... here's a close up of the label. Let me know if you need any other details.

TM - good luck with the drop light shields. I had the same plan, but it will take a lot of tweaks to make it fit in the plastic cover... so I have not tackled it yet.

Well, how about that for luck. The one 3/4-HP I have seen (own - Maroon & Cream) that has 1/2" arbor and is single voltage.

Don't get me wrong, it is an awesome grinder! I use it for 90% of my wire wheeling, and it is near impossible to stall it.

Here's hoping you get it CalsX52.

Thanks D, I recall that post now. I'm not sure if I'll get to it any time soon either! like I need another project.

Here's a reminder about the cover/drop light shield fitment "challenge"

 

[linwood]

Exmaxima1 thanks for the info, when I get off work I'll check on the brand of paint. I know the dark grey was a hammer and the silver was a metallic.

I see what you mean.

Looks like the Donald's hair piece.

 

[CalsXS2]

So where are you guys getting the "EXPERIMENTAL" shades.


BTW. Why is there also a plastic cover. I assume so you don't burn your face?

 

[vertguy]

The metal shade in my post is an old school trouble light shield with the grate removed. More details in this thread as I also linked to some options for a metal gooseneck and socket. I never got around to trying to make the 2 pieces fit as I found a couple used block lamps that were complete.

Yup, same one that I ordered from Amazon.

Just thinking out loud - I have a CM metal shade that I'll try making a template from thick stock.

Then lay that out on top of the new shade, mark cut lines, and shape it to fit the plastic cover.

OR

Make a shaping buck from the CM shade, trim and beat the new shade into shape.



I figure, I can play around and see if I can cobble something up for at least these 2 Blocks.

If you used aluminum, I would think that would work, but it sure would be a labor of love.

This was just played on TV and we talk enough about bearings on this thread that I thought that this would be interesting. It's a "How It's Made" episode for ball bearings.

Yes, that was cool, listened to it on my way home from work.

 

[davethorik]

I commend you on your philosophy and look forward to pics. of the next Blocks.

Let's see, there are round tops: 1/4 - 3/4-HP, flat top: 1/4 - 1-HP, pre-Blocks, Industrial Rated, Commercial, HD, ....

Oh, davethorik - yours is the 2nd 1/2-HP m-397.19400 with the quench tray knock-out still in place, seen here recently.

mtwaterguy's

Torqueman, here's a shot of the bottom of my new block. The dark stuff Is mud, the grinder is in really good shape just needs cleaned. The bottom says July 26 1974 A.

 

[torqueman2002]

Sweet!

 

[CalsXS2]

I need your guys expertise.

So I have the 3/4 hp model 397. 19350 on the way. It has a cracked glass, and missing light covers. I have a request into the seller for a better picture of the glass.

I have run across a 1/3 hp model 397.19580 industrial model with good glass I think. I seen this one awhile back but wasn't interested. Has a crappy grey paint job. And they wanted way too much for it. And it's missing the light and quench tray.

I looked up the models on line and the glass has different part numbers. But. Do you guys know from experience if they will interchange.

Torquemans maroon ones glass looks different than my same 3/4 hp model I think. So one of them may have been changed.

I have an offer in for the 1/3 hp, which I made not realizing the light was missing. But I offered $20 and my old china bench grinder. They're going to run it past the boss tomorrow. I'm starting to think I offered too much if all I'm going to get is the glass.

Assuming the glass will interchange, would anyone be interested in this 1/3 as a whole, or need parts off of it.

If the glass won't work I'm not going to get it unless someone can use some parts.

If anyone is interested in this 1/3 as a whole with the missing parts mention, or just parts off of it pm me. This will help me decide weather or not to get it.

First/top 3 pics are my 3/4. Last/bottom 3 pics are the 1/3 I might get.

Safety glass cut to fit at a glass shop around here is about 6 bucks for both sides.

The eye shields on the Maroon Cream 3/4-HP m-397.19350 has the eye shields from an older Block.

There are 2 size metal framed eye shields. There is a comparison in the thread in my signature link.

I am 99% certain they will fit a m-397.1935.

Is there an outer frame on this cracked one. Do I need a new frame, or at least can this be fixed.

No outer frame.
Use clear epoxy.
