Little Things Make Me Crazy

knobs and wedges 005

 

I’m slightly anal about some things, while other things don’t bother me at all. I have been masquerading as normal for a long time, but sometimes the little things just get the better of me. A while back I bought a quick change quill lever for my Bridgeport mill that was obviously an offshore piece (by the price), but good enough quality for me to ignore that it was Chinee. One of the most obvious tip-offs is that it came equipt with a LOVELY  red knob. This has been making me crazy for six months or better.

Changing an Arbor on a Jacobs Drill Chuck

drill chucks 001

 

Anyone who owns old machines probably scours Ebay for orphaned tooling for their pride and joy. One of the benefits/curses of that pastime is that you tend to accumulate broken/wore out tooling. Some of the broken drill chucks I have acquired over the years are starting to look pretty good to me considering some of the prices I’m seeing online, these days. Last year I bought an Llambrich drill chuck (made in Spain by Jacobs Chucks) at the CAMS Yard Sale with an R8 arbor that worked real nice (initially, anyway). The last time I used it there seemed to be an awful lot of runout, and I put it aside for future investigation. Today I decided to take a look at it……………..

“How much is a Bridgeport Mill Worth?”

 

 

work for cold beer

 

I get alot of questions about what different machines are  worth, and to be honest; unless you are standing right next to a machine, it’s tough to say. About the best I can tell most guys is the most important factors are: Location, Condition and Tooling. Thats not much help to anybody that is looking to buy a new toy. The other day I got a note from a site viewer that made me aware of just how many aspects there are to the fine art of buying a machine, and how badly I missed the mark on just ONE of the considerations when I replied to his inquiry. Heres the Email:

Jet Belt Grinder Modification

belt grinder III 006

 

I’m a habitual Craigslist troller, and when I found this Jet “bench grinder” for $100 I snatched it up. It was a 3450 RPM 1 HP deal, with a 4X48″ belt sander on one side, and a 8″ grinding wheel on the other. I had a 2X48″ Kalamazoo (partial) belt grinder that I wanted to adapt to the wheel side, so that I could have multiple grit capabilities on the same machine. Belt grinders are about as handy as it gets for fabrication, and this seemed to a good way to go.

Fixing a Permanent Magnetic Chuck for the Surface Grinder

magnetic chuck 001

 

I have been looking around for a cheap magnetic chuck, (or power supply for the one I’ve already got) so that I could put my surface grinder to use. I ran across this one at the CAMS Yard Sale really cheap, and bought it to play around with. Its a permanent magnet type, and I was told it was a little weak. There is an Allen bolt on the side which operates a cam that releases the magnet. The action of the cam was stiff, and the mag didn’t seem to release. I figured it couldn’t be all that hard to fix.
