This is an off the cuff suggestion -- perhaps a parallelogram mount?

I wouldn't think that the weight of a 75mm scope would be prohibitive; perhaps there are other problems with such a set up that haven't come immediately to mind. ( I have never used a p-mount.)

Chop Saw Blade

Posted By steve cambell

A wood crosscut blade will work fine if you can't find a dedicated blade. The oxide blade will work, but it isn't the best thing to use.

You really need to use some kind of "lubricant" to keep the soft aluminum from clogging up the teeth -- probably why people also reverse the blade. You can use candle wax, we use a "tallow" product that works really well. Just letting the blade cut the the lubricant for a second or two every other cut or so should be good enough.

Good luck,
