Old Becomes New Again

There are many who pass off the old PM plans as being obsolete, but for being obsolete, it is surprising how often they show up again as new ideas or as new versions of an old idea. In many cases you are not aware of the previous versions in the old PM or PS magazines. I have been victim to this a few times and it's both, a boost, and a let down, that someone else thought of the idea first.

Following is an example of this conundrum. Back in the late thirties PM published a plan for a useful horizontal disc sander, it's easy to see how this could be very useful, especially for sharpening edge tools, with a few jigs to control the angles.

Below is the plan for the disc sander along with a plan for a beast of a belt sander. I got this from a Popular Mechanics Press book titled "Forty Power Tools You Can Make". It was published in 1941 and the plans are all taken from previous PM magazines. I have posted most of the plans before, in the Shop Notes posts.



Dave Gingery does a recreation of this disc sander in his first book in the "Metal Working Shop From Scrap" series, "The Charcoal Foundry". Dave recognized the versatility of this disc sander for pattern making and tool sharpening and built one almost exactly the same as the old plan in PM. This may have been a product of Dave's very creative mind, but as I like to say "Their's nothing new under the sun" old becomes new again, just a little different.

Don't forget to read Dave's nice little write up on the disc sander and it's uses.

Disk And Spindle Sander Plan

So I am pretty sure I included this plan in a previous Popular Mechanics post. I found this plan today in my Plans-Projects-Models file, the resolution is better than the previous file and my new software cleaned and straightened out the file nicely. This is an advanced very heavy duty machine for the larger workshop. With a good finish you would never know it, but the machine is all built from laminated plywood. The drive components are mostly hardware store stuff, bearings, shafting etc. The double shaft motor is harder to find new, but if you can find a salvaged 1 hp grinder (usually 10") that would be perfect. Failing that a regular motor with an extra idler shaft mounted above the motor will give you drive from both ends. One thing I would change is the disk to a 12" or 16" disk, it would be easier to find replacement disks for these sizes, and would be better sized for 1 hp. Size your spindles to accept standard size sleeves for easy replacement. Or another option is to order and adapt a set of spindles from a machine supplier like Busy Bee .

Getting The Most Out Of Your Abrasive Tools

So from Delta Manufacturing Co. comes this small manual dealing with grinders, belt, and disc sanders. Delta published many "Getting The Most Out Of Your . . . ." manuals covering most shop machines. More than one edition of each manual was published, this one was from 1939.

I have Lindsay's reprint of this copy, but I had a small file on disc. The pictures have a pinkish tinge to them but otherwise its a good copy. Some good information, jigs and tips for operating this equipment here, regardless of brand.
