Has anyone done anything different to achieve the same results as the Eccentric Mounting Tubes so the bandsaw can be left on when the SS is raised?

You can make a "shorty" or "mini" length Mark V. Then the radius of the lifting way-tubes is tighter, and can clear the bandsaw...

my mini is set up as a sanding station, so I want to use my other SS. but how does a shorty or mini change anything, when you lift the left side, it's the same distance from the BS as a full size SS?

unless I am missing something here--it's been a little cold and I have brain freeze:)

I may have to go double-check sometime, but here are some rough calculations of what I was thinking:

If a way-tube is 48 inches long:
Lift the left-end by, say, 12 inches vertically, where it would be wanting to strike the edge of the aluminum bandsaw table.
The angle of the way-tube at the right-side pivot is arcsin (12/48) = 14.5 degrees above horizontal.
The amount that the left-end of the way-tube has "moved horizontally to the right" during the 14.5-degree lift is only 48*(1- cos(14.5)) = 1.52 inches. So it's easy to hit things on the left side, like the bandsaw table.

If a way-tube is only 24 inches long:
Lift the left-end by, say, 12 inches vertically, where it would be wanting to strike the edge of the aluminum bandsaw table.
The angle of the way-tube at the right-side pivot is arcsin (12/24) = 30 degrees.
The amount that the left-end of the way-tube has "moved horizontally to the right" during the 30-degree lift is now 24*(1- cos(30)) = 3.2 inches. Compared to a full-length way-tube, the clearance at the bandsaw has increased by over 1.5 inch.

Worth cutting your tubes? Probably not. Just interesting stuff, I guess.

Here is how I dealt with that.
A picture is worth ....
this is screwed in dowel of wood big enough to fit in there
and the plates of metal are about a quarter inch thick

Sorta like these! 1/2" thick steel works better(less whippy).

Here is a pair of eccentric tubes I made using a South Bend metal lathe and a belt sander. Nice to have tools!

Nice job, Peter, but I must ask! What particular function do these serve that necessitates the 7" or 8" inch lift that these would provide.

Could you please show a picture of these installed as you intend to use them.

I made them to mount a jigsaw that I bought which was without any tubes, seen here:

Probably straight tubes would have worked but I don't recall why I decided to make them eccentric.
Anyway, they work!

Thank you. Not being an owner of the jig saw, I had no idea of how these would be used. Very appropriate. Are you prepared to take orders?:rolleyes:

No kidding. There are people out there making money on items just like these.
