Re: Craftsman 101.07301 with a 383.22970 chuck
That key is not for that chuck. The chuck you have takes a spanner wrench that goes in the holes on the chuck, spinning the outer ring. Another square wrench goes on the flats on the back of the chuck

Re: Craftsman 101.07301 with a 383.22970 chuck
It looks like the chuck on my little Unimat. I believe you just use a piece of rod (called a tommy bar) to turn the scroll to tighten it. You may need to use a cresent wrench on a jaw for leverage.

Craftsman 101.07301 with a 383.22970 chuck
I have a quick question, purchased a 101.07301 with a 383.22970 chuck and wanted to know how to use the chuck? The seller told me it came with a working chuck and key, chuck was a bit frozen so i took

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Whenever I began learning to use tools of any sort it began with how to set up the tool so work could get done safely, efficiently, and with quality. Obtaining the proper cutting tool with which to do

Guenther¡¯s reply may have seemed harsh, but I don¡¯t think he was far off target. I¡¯d have instead said that any decent machinist - or anyone with experience running one of these light lathes -

Guenther, most of us here are amateurs. Not professional machinists. That is quite enough. If you do not have something constructive to say, do not say anything at all. Bill in OKC William R. Meyers,

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Hi Bruce, If you have a choice between 6061 and 7075, the less expensive option will be fine for what you're using it for. You're not going to be loading it very much - 7075 is more prone to fatigue

Re: Need Pulley for Craftsman Speed-Reducing Attachment
John, Nice article! Procedure look good, I'd use different tooling but same idea. Not going to make one for this episode but I have made a pulley or 2 in the past. Trued up a couple die cast ones as

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Bruce, One additional thing to add to your literature pile. I read and applied what i learned in this write-up when I was making the motor pulley for my lathe. You might find it useful as well. Good

SpeedyMetals.com sells Aluminum round in 2011, 2024, 6061, and 7075 grades.? 7075 round aluminum can be had up to 12¡± diameter from Speedy. Speedy also sells Class 40 gray cast iron up to 12¡±

Re: Need Pulley for Craftsman Speed-Reducing Attachment
So you're planning to create a pulley, eh? I'd really like to see a video of that! Most of us have to settle for fabricating things.
By Jim Irwin · #107053 ·
Re: Need Pulley for Craftsman Speed-Reducing Attachment
Bruce, Yeah, 7075 is expensive but 6061 would work better than fine. 7075 just cuts so nice. Going cast iron is not going to save any money regardless of how you do it unless you pour it yourself!

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Making that large pulley from a casting is definitely the way to go. Making it from bar stock, there would be - as you say - a lot of metal to whittle away. Cast iron versus cast aluminum - that¡¯s

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Bruce, Not necessarily cheaper, but I want it cast iron. Plus, it will be way less work to turn down a cast blank than a solid chunk of bar. I probably failed to mention that it's a 4 step pulley, and
