Baldor 1/3 hp Bench Grinder Cleanup

The recent Foley Belt Sander/Grinder went so well I could not help myself.  Eyed this one from the roadside at local residence close to home.  Been exposed to the weather for almost too long.  Plugged her in and she fired right up and in classic Baldor form took 10 minutes to stop spinning after turning off.  Was not going to re-paint but now I am in deep so what the heck.  Came apart relatively easily (nice to work on quality products).  Missing side covers – may have to make some or deal without.

Foley Belt Sander Grinder Model 371

Nifty little 1×42Belt Grinder/Sander made by Rockwell for Foley.  It is basically the same as the Rockwell 31-350.  Freebie from a barn clean-out (Thanks MB!).  Took some scouting around for replacement wheels but alas a shout out to James Liechty (jimliechty@yahoo.com) who has sourced replacement pulleys and other parts for these and offers them at very reasonable prices.

Took her apart, cleaned up all the saw dust cake, installed new wheels for sanding belts, replaced one v-belt pulley, replaced the power cord (not done yet) and that was pretty much it. My initial thoughts when it showed up were it was pretty flimsy construction and the plastic wheels made me skeptical but all those thoughts have passed now that it is up and running.  Runs great, hit a few pieces of metal with it, no problem.

First Plunge Type Form Tool for Lathe

Messing around on the turret lathe got me re-interested in creating some forming tools.  I have watched enough videos to be dangerous and gave it a shot.  First tool is pretty crude but I was glad to see it cut as well as it did.

Cut shape on mill with tapered end mill and finished up on a grinder. Got cherry red with torch and quenched with water (I know, more work to do studying heat treating – but it cuts). Finish not great but I spend zero time on the honing/sharpening.

Rivett 918s Second Tool Post

Created adjustable sub-plate for tool posts I picked up recently at the Cabin Fever Expo.  May need some additional modifications but has adequate travel to situate the form tools that I want to play with.  Simple plate with slots to allow adjustment over the work piece.  Don’t need much travel as the form tools will stay as close to the spindle as possible.

Tricky part of the second operation lathe is getting front and back tool post in sync.  Also, depending on some of the tools I use in the turret it require sthe cross slide to be pushed up pretty close to the spindle.  Hence they typically come with factory installed risers and corresponding tool post.

 

Rivett 918s – Added Knurling Capability

Brown and Sharpe 210-120 Knurling Swing Tool.  Nice addition for the Rivett 918s.  Takes 5/8″OD – 1/4ID – 1/4″ Width Knurling Wheels.  Came with the “fine” diamond (male or female tbd).  More wheels to come and and a bit more studying.  Great document for anyone playing with knurling  Reed Machinery – Knurls and Knurling has been a great help.

The swing tool is interesting.  The swing allows the placement of the knurl on the part to be flexible.  Single wheel limits patterns formed by multiple wheels but diamond patterns available so not a worry.  Initial test shown above – not too shabby.  Need to work on the push bar that contacts the swing arm, just pushed it with the cross feed plate for now.

Riser Plate for Rivett 918s

Working out a t-slot riser plate for the Rivett.  With the tooling I am using in the turret it is hard if not impossible to get the cut-off tool close enough to spindle and keep the turret from running into the cross-slide.  The t-slot riser plate will allow enough freedom of movement to accommodate the shorter turret tools.

I have a few Brown and Sharpe Tool Posts for Square Tools – They may be a little big but I am going to figure out a riser plate to mount these with for shits and giggles.

Walker Turner Double Carbide Grinder Rehab

Not a restoration but a good clean up of the Walker Turner Carbide Grinder.  Cast iron table surfaces came out real nice, all working surfaces also cleaned up well.  Put back together and added a few new AO Wheels…runs like a charm.

Liberty Tool Visit

First visit this trip to Maine….got a switch panel I needed for 3ph rotary converter setup.  A nice yet unmarked 3″ sine bar a few little vee blocks and some nice ground lathe bits.  Coil was 75 cents so I took a chance it might work on my Rivett brake…no dice.  A little research shows it is more than likely for an early mag starter.  All this stuff plus the Rockwell Carbide Tool Grinder project from previous post… $29!
