I have a project in which I need a 'die grinder' type device for power, but I don't want the RPM of a typical die grinder.
I am looking for something to power a cutter which I am designing, but need the RPM to be drastically lower. Tho RPM on the tools I have seen are in the range of 13-20K and I am looking for something in the 500-1000 or even less range. (At least at this time.) However, I still need to keep the torque of the machine to run the cutter. I am afraid, although I don't know for sure, that the high RPM will cause too much heat in the foam I am cutting. (memory foam type material)
I am not familiar with airtool workings. I have and use several, but that is it... I use them. The most I do to them is oil them.
I suspect there is a way to decrease the RPM via orifice reduction etc. But I also suspect that would drastically decrease the effective torque. Otherwise, I suspect I would need to change the internal 'gearing' in some manner, which I am willing to do, if it is reasonably accomplished by a 'novice'. I am pretty handy, and not afraid to take on a task, and I am willing to 'sacrifice' a few HF tools in order to give it a try. But, I don't know where I'd begin.
If you know of a die grinder/cut off tool with either a variable speed or MUCH lower RPM, that might work for me without necessitating all the hassle. I also don't know whether simply turning down the air pressure would decrease speed without torque, although I would think both would be affected.
Straight cutters, saws, hot wires, etc will not work.
I need to be able to slow down a cutoff wheel machine or something along those lines. Something similar to or along the lines of the pic below.
