Using a Magswitch AND double sided tape?

[Wade Lippman]

I am making a jig that absolutely positively can't move even a little bit during a bunch of cuts. A magswitch might work, but it can be nudge a bit. I am thinking that if I put thin double sided tape under the magswitch it would become imperturbable.

Aside from having to get the tape off my bandsaw table when I done, am I overlooking any reason this is not a good idea?

Sounds doable but, I would be tempted to just clamp something in place if at all possible.

[Ben Rivel]

Yes as Glenn mentioned is there any reason why you cant just clamp something to the table?

Okay, maybe more detail is required. I am cutting 8 arches that all have to be identical. I have made a board with a hole drilled in it, and will use a magswitch in the hole as a pivot. Screwing the 8 pieces to the board and then rotating through the bandsaw blade will give me what I want, as long as the magswitch doesn't move at all.

Yeah, clamping the pivot might have been better, but I already have the board set up for the magswitch. Speaking of which, why the heck is the magswitch hole 1.57". What is wrong with 1.5 or 1.63"?

When I do that sort of thing..... on a much smaller scale of course, I create a template, cut close, then use a router with a pattern following bit to make them exact.

Sounds as though you are better off making a circle cutting jig for your bandsaw to cut these arcs which will be a more versatile long term jig. Plywood platform and a pin would be more stable and not move during any of the repeatable cuts.

magswitch hole 1.57" may be metric, since it's barely shy of 40mm.

Magswitch holes are in metric.

Must be a metric size. 4cm is 1.5748".

Wade, there's nothing wrong with 1.5" or 1.63".

What's wrong is you're using the wrong measuring system, the Magswitch uses a 40mm hole for mounting.............Rod.

[Wade Lippman]

I guess I need to buy a 40mm forstner bit. I drilled 1.5" and sanded to size.

The tape and magswitch worked fine. A circle jig would have been a better idea, but I had already sanded the 40mm hole and couldn't walk away from that.
