I've got someone wanting to sell me a Black and Decker Super Service Valve Refacer for $100. Does anyone have any information on these? My last 2 rebuilds. I also got reprints of the instruction manual from www.BeamEquipment.com.
One of my running buddies has one that is about the same age that I use once in a while. There should be a pump and reservoir of sorts for coolant for the valve facing machine.

Be damned careful when you use the diamond nibs (screw with diamond on end) to dress the stones as it is real easy to knock the diamond out and ruin it and they run right at 40.00 each. Go gentle when you dress the stones. It looks like you might be due for a new stone on the valve facing side. The other side is to dress and trim the stems.
Click to expand.The pilot shafts for the refacing stones should just press into the guide with a tension fit. There should be a removeable T-handle that fits on one end of the pilot. If you've got something that looks like it would thread into the guide you may have some knurling tools. Kind of a funny looking tap affair.
Did you also find any reamers about the same diameter? These would be used to finish size the guides after knurling. When you clean it up, don't get too carried away. Fight the urge to make it look brand new. It's standing pretty proud just the way it is. Before you spend a bunch getting this going, these use a three ball chuck.
The balls tend to wear, so see if you can get new ones. To check this, use a discard valve. Make sure you have coolant running, grind the valve, as you finnish, hold the handle that moves the stone on the valve in one position as you use the feed pressure to move the valve and the stone apart. NOW, before you remove the valve, stop the machine, note the position and rotate the valve 180 degrees in the chuck. Start up and bring the valve to the grinding wheel again, if it hits the whole suface of the valve at once, you've got an accurate machine. If not, chances are it's got chuck issues. There's probably lots of people here to help, as I'm a ways away- you could contact me, I could go over a few things like this on the phone.
Bill, the first thing I would do after a basic cleaning, is to check the run-out. Looks like the old 3 ball chuck set up. Some known good valves or better yet a nice new piece of drill rod, 3/8' diameter will be fine. Mount a dial indicator anywhere to the machine and turn the spindle by hand. With the indicator tip riding on the drill rod of valve face. Report back when you have a fiqure.
These machines like many from that time were made to last and will do a excellent job. Like most machines, they are only as good as the operator. GOODSON should have some parts and the consumables for it.
Want to practice take a big old intake valve and start cutting angles. Start with a 45, then coat the valve with Dykem bluing or even a Sharpie majic marker. Now cut 5 degree increments, larger and smaller than the 45. Each time put some bluing on the face before cutting the new angle. When you get 7 diffrent angles on there clearly, you graduate!
Best of luck, TR.
I have a valve refacer that has a similar setup. Whan you set it to 0 degrees to use the diamond tip to true up the stone, the stone is trued at an angle, although I'm not sure WHAT angle. When you remove the wheel truing device, and set it back to 45 degrees, for instance, the interaction between the angle of the face of the grinding wheel and the angle the valve chuck runs at produce the correct 45 degree angle on the valve face. I'm not sure why some of these units have the grinding wheel faced at such an angle, but I suspect the interaction between the angled stone and the valve face produces a better finish, possibly because of less vibration or 'chatter'.

(I believe it is a KO LEE, but I'll have to check and see when I get to the shop).
