bandsaw speed reducer anyone done it

[AR1911]

The 4x6 in vertical mode is still not a vertical bandsaw.

I used a 60 rpm gear motor, direct swap, for 110 fpm. Works great

those motors are common in industrial applications like conveyors

The small horizontal one I got from Harbor Freight does stand up and comes with an about 8X8 inch platform that can be temporally bolted on to stand up and use as a hand feed vertical band saw. So some do have that capability. It would be nice to have a full time vertical one though.

Sure, as does mine. But I still needed a vertical bandsaw, even if it was a converted wood saw.

This might sound crazy but is there any reason you couldn't use one of the crappy import rotary tables (less than $50) as a speed reducer? could you use one in place of a gearbox as JimDawson did?

I've used ride on train sized worm and wheel for some reducing gearboxes i've made, their Often on the ebay and generally quite cheep and quite heavy duty.

hobbing ones own worm wheels must put on todo list

I second the 90 to 1 reduction box and a 2 hp treadmill motor that has adjustable speed control. That will slow you down enough to be able to cut any hardened metal that could possibly come along. I would set it up so that a belt change runs the gearbox and putting it back to original position allows for higher speed wood cutting too. Should be fairly straight forward and a simple mod if you can find the gearbox for reasonable money. The treadmill motors are a dime a dozen so that isn't really an issue at all. Hope this helps steer you in the right direction.

This is a Harbor Freight 14" saw that I cut wood with for years before finally replacing it with an old 20" Powermatic that I found a good deal on. It is a 1725 RPM motor directly driving (a 1-1 ratio) a 30-1 reduction gear box that I got at surpluscenter.com for under $100 and another (roughly) 2-1 reduction in the final drive. It gives me a blade speed of about 80ish feet per minute. I may change the lower pulley to speed it up a little. I was originally afraid that the final belt drive might slip, but it has not been a problem.

Here is what I did to my Horrible Freight 14" bandsaw to cut metal. It works amazingly well!

This is not a bad way to go either, some good deals can be had on DC motors/controllers if you shop around. I had a 90 VDC motor on a 9" South Bend lathe I used to have. It worked well, they have a surprising amount of torque at low speeds.

This is the way I did mine only I used a chain and sprockets for the final drive as belts slip too much. It was featured as a project in the early days of this forum but can't seem to find it back
