I'm having fun reading the posts. Sorry about the damaged pre-Blocks.
I have noticed that the 1/3 HP pre-Blocks m-115.xxxx, have the wheel guards drilled and tapped for covers, but the 1/4 HP do not.
I was lucky enough to find one cover for my 1/3 HP pre-Block (LH I think), but after 4 years of looking, I have all but given up on finding the missing cover. They're very rare to find.
Best of luck getting the guards back in shape.
Oh, I have a line in a couple of Blocks. If I am successful, I will post them up after returning to SE Michigan.

It was a safety issue, they just wasn't mandatory until OSHA stepped in. It's been posted before but I forget the date, I'm thinking they said in the 60's.
Can someone with a stock Craftsman lamp post the length of the flexible tubing?? Thanks!
Here is mine for $53. Its rusty but it runs real smooth. I would like to try to remove the rust and somewhat bring the outside back to life. I don't have any experience doing that though. Any tips would be appreciated.

Jeremy: What McB is really trying to say is one of the best ways to clean rust off of your old block is with a wire wheel off another block grinder. of course you can use evaporust or simple green or WD 40 on a rag with some elbow grease.
or if you take it all apart and take it to a friend or another local GJ member they will maybe let you use their wire wheel and their grinder.
good luck
Vert,
This is a lousy picture. But, it is 12 degrees in the garage, so this is as good as it gets tonight.
I have 3 blocks and the length is the same on all - 18" (ignore the mounting bracket on the end). However, the diameter varies as follows:
1968 3/4hp Industrial Rated Round Top - 5/8" diameter
Early '70's 1/2hp Commercial Roundtop - 1/2" diameter
Early '80's 1/2hp Split Phase Flat top - 5/8" diameter
By the way, this one pictured is a leftover part. The goose neck is original of the above 1968 Block (5/8" x 18"), but the lamp shade is off of an old desk lamp.
Thanks McBrownie... doing some research on how to piece one together since finding a lamp without a grinder attached could be a lengthy search. Think I have found all the parts except the inner light shade/reflector and I have an idea on how to potentially fab one of those. We shall see, but your measurement does help as 18 is one of the standard lengths for the flexible gooseneck![]()
Yes, but you can't tell anyone!Extras ? [prairie dog pose] Do tell !

Sooo much suckage from Torqueman2002 (and others) over the course of this thread... I can't believe how many of you find nice clean little used blocks (or at least complete ones for $25, $50 when usually what I see (when I see them) are double those numbers and have serious flaws, like missing everything but the inside wheel guards (missing spark arrestors, outside guards, eye shields, and tool rests) and also have the armature threads stripped, etc. ... I can check CL in SE Michigan for you. Not sure how much shipping & packing is to you, but from 48334 to TX for a 1/2 HP Commercial (37 #) Block, it was $40.09. PM me if you want the details.![]()
Picked up a 1975 Craftsman Commerical 1/2 HP grinder (Model 397.19440) today for $40. It runs smooth and shuts down the same. This thing has some POWER. I'm going to clean it up this weekend.
I'm really tempted to pick up a 3/4 HP near me now. Welcome to the Block grinder support group.That's how I started, 1/3 HP nice, 1/2 better, .... 3/4 HP are very powerful!
Be sure to post pictures of BOTH your 1/2 HP and the 3/4 HP you are going to go get!

Waltripany pictures to share with us yet of the mysterious 3/4? some of those 3/4 HP have the very stout tool rests and bigger water tray and if it's a commercial one even better.
No picture yet. The seller is a bit of a flake and jerk. He hasn't sent me a picture yet.

Vert,
Thanks for forwarding the grand brass website. Really nice stuff there.
TM: did you ask a Mod to move over your other block grinder threads so they are all in this section? if you are having an issue just make a post on that thread asking the mods to move it and i'll PM one if they don't see it. thanks
