Rebuilding a Delta Bench Grinder

There was an Email on the CAMS server last week for a couple of Delta bench grinders for sale CHEAP (one 3PH, one 110V). Both had floor stands. Too good to be true, but I Emailed that I was interested, and forgot about it (too late, I thought). Well long story short; I ended up with the two grinders (less stands), after the lucky buyer took the bases out of the deal. I would have liked to have gotten the bases, but this deal was good enough to grab up, anyway. I wired the 3PH grinder up with my new test circuit, and lo and behold: it worked!
Unfortunately the 110 volt grinder seems dead, but was complete enough to be worth saving. I stuck it off to the side, planning to play with it after a while, but started to think about all the “future projects” I’ve got around here, and decided to pass some of my good luck along to the next guy. It took one Email to sell the bad grinder to another CAMS guy for 20$, and he is plenty happy to have the parts to get his grinder up and running.
Heres some pics:

Rebuilding an Atlas Horizontal Milling Machine

I’m reaching the tail end of the rebuild on my US Machine Tool mill, and looking for the next project. I’ve got plenty of plans for different things to do, but someone spotted my old Atlas in the USMT rebuild blog, and asked about it.
I bought the Atlas about six months ago from my friend Rich. I had put out some feelers for a small horizontal mill, and Rich had this one sitting in his shop collecting dust. The machine had been rebuilt previously, and by the looks of it, been put away pretty much unused. It is in need of a good cleaning, and a tweak here and there.

Rebuilding a United States Machine Tool Co. #1 Horizontal Milling Machine

This entry is to document the disassembly, cleaning and overhaul of a Burke No. 1 Horizontal Mill purchased on 9/24/2011, its bound to be a lengthy process, bear with me.
The story starts with a friend (we’ll call him “Steve”), sending an Email to the CAMS group with a list of the goodies he’ll have for sale at the 2011 CAMS Yard Sale. One item that interested me was a Van Norman 1R mill, and I inquired about it. It turned out to be more mill than I needed, and I told him I was really looking for a dedicated horizontal mill, without all the bells and whistles; a “crab”. At this point he mentions the old Burke might be what I’m looking for. Fully operational, ugly, and cheap, I’m hooked. Steve is a crafty individual; He knows if its ugly and cheap, I’ll probably be interested. He asked me (after the money changed hands) “Did you feel it when I set the hook?”. Frankly, I never saw it coming. All kidding aside; Thanks for the great deal, Steve. This is the sight that greeted me when I arrived at the Stallings Institute of Industrial Antiquities:

My First attempt at Casting Aluminum

I have been wanting to cast some aluminum for some time. I used to cast my own bullets a few years ago with a LEE induction furnace, and it was a very satisfying undertaking. Lead has a very low melting point, and easy to work with. Aluminum has a higher melting point, but well within the backyard casters reach. I have been stockpiling Aluminum for some time, planning on building my own furnace, when a buddy of mine mentioned he had one for a very reasonable price. I carted it home, and its been a few weeks till I was able to spend a whole day getting to know it.
My dream furnace would be waste oil fired, and this one is coal powered. I figured; I gotta walk before I can run, and this one fit the bill. Its a well engineered furnace, and the workmanship on the tools is real nice. It came furnished with three 12 pound stainless crucibles, and three smaller crucibles, and all the associated tools to handle them.

It has a new Dayton squirrel cage fan thats whisper quiet to fan the flame.

Lubrication Cross Reference Chart

A buddy of mine had a chance to get a real good price on some spindle oil, and was looking for the equivalent viscosity for Mobil Velocity #6 (my preference). It took me a while to find this file in my archive, and thought it might be of interest to other guys, so I’m posting it here, for easier access. Hope it helps.
