“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:

New Lighting for the Bridgeport Milling Machine

 

 

mill light 2 005

 

One of the things that bug most people as they get older is poor lighting in the shop. If you want any degree of accuracy when doing the work we do; you will need good light, and (in my case) some magnification. A few weeks ago I got what I considered a fair deal on medical magnifier with florescent lighting. It has a 5X diopter lens, and I really liked it from the start. I mounted it above my lathe, and it really helps when doing “close” work.

Optimizing Shop Space (or: A Corner Shelf From Scrap)

001

 

There is a corner in my shop that is more or less dead space. For some reason its too small to fit any machines in, and all kind of Use-it-once-a-month stuff finds it’s way there. I don’t have enough room in my shop to waste any space, and this space was crying to get filled with something for quite a while. I can’t put a filing cabinet or any conventional kind of shelf in there; its just too small an area.

About a month ago, one of the contractors at work sold me a small pile of plate steel for what amounts to beer money. I have been sitting on about 600 LBS of 7/16″ fish plate in varying shapes. I had one 36″ round that looked like it would be a good candidate  for a corner shelf, if it was quartered.

Cleaning Up My New “Albrecht” Yard Sale Chuck

keyless chuck 001

 

Yesterday at the CAMS Yard Sale, I parked my truck and made a frantic dash for the sellers tables before I unloaded all my stuff to start selling. This was one of the first items that caught my eye.  I had a decent size keyless chuck on my want list for a while, and there it was, and on an R8 arbor, to boot! I picked it up and it looked to be in good working condition, but maybe a little banged up, but it was an Albrecht! I started doing the rebuild in my mind before I even asked the price, and was shocked when Chris told me $40. Thats a hell of a deal for a 5/8 Albrecht chuck on an R8 arbor, and I didn’t think it would be wise to question the deal and happily paid him and went on taking some pictures.

Chinese Lubricants; Its Just Oil, Right? (Oy Vey!)

As one might expect, I tend to get involved in alot of discussions about machine tool lubrication on different forums (against my better judgement). My views are VERY CLEAR: buy good stuff for your machine tools, and they will love you long time. PERIOD.

The other night I posted some sources for the ROY DEAN  DE112 grease for the cone pulley and back gear on the South Bend Lathes on the South Bend Lathes group on Yahoo. This is the grease that SBL recommended as the lubricant for these parts when it was determined that the oil points were not being lubricated on a daily basis.  I always wondered why some lathes were marked “OIL”, and some marked “GREASE” on the cone pulley and back gear. It is my IMPRESSION (because I have no facts to back it up) that the parts marked OIL and GREASE are identical, just the lubrication requirements are different. It was felt that in production shops that the lathes weren’t being lubed with oil every day, so SBL changed the lube to the ROY DEAN DE112 grease applied ONCE A YEAR. Their feeling was that that should provide enough protection to the cone pulley and back gear. Thanks to Jim B from the Yahoo South Bend Lathe users group for that tid bit. I have to believe that SBL spent a little time and money researching what grade and viscosity of grease or oil would work best in this application. Their word is good enough for me.
