SPT’s What When and Where

[chapmanruss]

Ed,

You are correct that those two holes, which have been cast in the Main Frame since the beginning, are for the bracket for the Belt Cover you show. There is a different Belt Cover Magna made that also uses those two holes and the same bracket part that attaches to the Main Frame. It covers less of the Belt and can be seen in the picture below on a Power Stand. It can attach directly to the Mounting Base which is another mounting option for the Belt Cover for different SPT's. So, if you were wondering what the center threaded screw hole in Mounting Bases was for, that's it.

In the above case it happens to be attached in the wrong position for use.

More recently, two additional holes have been added to the Bandsaw Main Frame. They are drilled and threaded holes for the Hub Safety Cover as shown below.

Hub Covers can now be found on the Mark Headstock too.

They are on all the gray bandsaws I have. No idea if they were there in the earlier Magna and Yuba versions. You can probably check on those.

They’re there on my ‘56 bandsaw as well…

…but this concept even predates the bandsaw, as this instruction sheet from 1955 shows.

Different guard but same two bracket parts in use since 1955.

The Instruction Sheet John shows in his post is for the same Belt Guard I showed in the picture in my previous post. It shows how to install it on the Jig Saw. The Jig Saw was introduced about or at the same time as the Mark 5 in March of 1954. The bracket was made to match the holes that the Name Plate/Cover attach to the Jig Saw through. Clever way of doing it, isn't it. The Belt Guard Ed first posted about is a later Belt Guard providing more coverage and protection. Having these Belt Guards able to attach directly to the SPT's would allow the owner to make their own stand with motor to use the SPT without having to buy an OEM Mounting Base for their stand.
