New Rests For Bench Grinder

This Baldor grinder has been in my shop since 1973 and for  unknown reasons  I never got around to making  suitable rests for it. This photo shows what I came up with after a few moments with a measuring tape.  The materials used were   3/8 X 1" and  3/8 X 4"   hot rolled bar stock, which were on hand.   The smaller links are 2" on center and the longer ones are 4",  yours will probably vary.  The rest   (orange) pictured on the LHS is the finished model with  3/8" carriage bolts acting as  pivots. The rests shown on the RHS are shown as a trial assembly to check  the fit and to mark which pieces were  to be threaded. These pivot holes were initially  drilled 5/16" dia. and temporarily mounted together with 5/16" bolts. The reason for this is,  5/16" is the proper tap drill size for 3/8"- 6  coarse threads...........more on that later.  All of the adjustments were  located on the LHS of the rests so that the pivots are all tightened with  a down stroke.

Step 1 Material Layout

Cut one piece and accurately drill out the holes (5/16" dia).  You can use this as a guide to layout the balance of the four identical pieces. I am presently without a metal chopsaw, so I used a 4 1/2"  angle grinder with a very thin cutting wheel. The length of each piece was marked out by clamping the sample in place and scoring the length, with the cutoff wheel,  then marked  the holes  in the drill press. This way all the holes are drilled  identically.  The sets were then matched up and marked, shown in a later picture.

Something I've done myself. I have another grinder I still need to make some sort of a tool guide or rest for. Here are some pictures of one pair I made:

A little tough to make out but I still have to make a rest for this grinder:

I want to make a perpendicular bar Tormek style rest and guide for this one.

Thanks for all your photos.......you have been busy! Keep us up to date on your Tormek work....assume you were eyeing this one (me too).

Actually I hadn't seen that! It is really cool. The bit holder is a lot like a drill sharpener we had in a machine shop I worked in. Though that one was milled steel, not cast aluminum or white metal or whatever the Tormek is made out of. And the one in the machine shop used a cup wheel and had a little angled sliding table though it was flipped it over just like on the Tormek, to grind both lips.

I figure I want to go with a Tormek bar style guide because this grinder arbor already has guide holes in it. Just I have some sort of they fit bolts slid into them now. I am going to have to buy some drill rod before I actually do the project.

I lightened up the image and drew some arrows where I mean:
