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.

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.

Hand Wheel Modification to United States Machine Tool #1 Horizontal Milling Machine

I was feeling a little depressed today about my lack of real “work” in the shop lately. Its not that I’m not doing anything, but that I’m always sidetracked by some essential task. This week it was getting the brakes on my truck to pass inspection, tomorrow it will be something else. Between my “real job”, and keeping up with all the site orders and the associated Emails; it gets a little overwhelming sometimes. The blog has been inactive lately, and its getting me down. I decided to dig out some pics I had taken of some old jobs and get them up, just to feel like I’ve been doing something.

I had to do a run of some lathe T slot nuts a while back, and found that the lever on my USMT mill just didn’t have enough travel to get the job in one pass, so I decided to make a hand wheel attachment for the mill. It needed to be large enough to have adequate torque to make a tandem 1/2′ deep cut in one pass (I’m lazy). I had a pretty good size hand wheel off some piece of equipment I pulled out of the dumpster at work that looked like a good candidate.

 

old stuff & new lathe 967

 

 

This is a blank I cut off some  surplus stock from work. I left it long so I could trim it once I had it sized to fit the rack spindle later. I wasn’t working off a drawing, as I tend to just wing it when I build stuff.

South Bend Lathe Recommended A B C Oils

South Bend Lathe A B C Oils

Most machine tool manufacturers have very specific performance standards for the care and feeding of their products to insure accuracy and long service life. In the South Bend Lathe publication; “How to Run a Lathe”, which is considered by many people to be the last word on the care and operation of the South Bend lathe, the use of “A, B and C Oils” were recommended. These are lubricants that fall into specific viscosity ranges, or have particular qualities. Judging by the amount of “survivor” South Bends on the market today, the recommended oils were more than adequate. In researching the current types of lubricants that have been developed in the last century, I found out that the oils originally called for in “the Bible” are still available, and in fact very competative in terms of performance.

I’ll be discussing only the Mobil line of lubricants, as that is what I have chosen to sell in the BlueChipStore. I chose them for availablity, quality, and cost. My reasoning was that buyers would want an ample supply of a time tested product at a fair price. Mobil lubricants fit the bill.
