Vintage Magna Accessory Mystery

Post by jpdalton »

Made a vintage Magna accessory acquisition this week, and was getting ready to post it to my “Share Your Magna Memorabilia” thread:

Nothing too amazing… it’s a follow up to an earlier post featuring a similar cut-off wheel accessory with a part number from the original 10-E/10-ER numbering scheme:

I figured the packaging sleeve was changed to green when the part number scheme was updated to the “12-xxx” style numbers. Since I like referencing these accessories with their original catalog appearance, I also pulled a couple of my vintage catalog sheets that showed the cut-off wheel with both the “old” and “new” part number schemes:

But this is where the mystery begins: the part number of the cut-off wheel I acquired (12-284) doesn’t actually match the cut-off wheel part number in any Magna/Yuba catalog or dealer order sheet that i have access to. In the catalogs and dealer order sheets, the cut-off wheel is part number 12-067… always:

…and part number 12-284 does not appear in any of them!

Any of you Shopsmith history buffs out there have any other references that may shed some light on this?? Thanks in advance.

Well, that stuff doesn’t cut itself - somebody had to do it!

I have been looking but I cannot find a reference to that part number in any catalogs or other reference materials so now my best guess. The green package P/N 12-284 says Grinding Wheel by Carborundum. It appears inside of that you have a Shopsmith Cut-off Wheel. Does that Cut-off Wheel have a part number on it? The Cut-off Wheel I have is P/N 175-1 and was never used. I don't recall if I have had one with the later part number12-067. If I did and it was used, I would not have kept it. I don't think it is safe to use such an old Cut-Off Wheel.

I was thinking the same thing - why the use of the term, “General Purpose Grinding Wheel”, unless that’s not a cut-off wheel. But a closer look inside the package shows a cut-off wheel (even the manufacturer calls it that) with the 12-284 part number.
