Motors, pulleys & movement - not strictly CNC related...

[m_c]

Lots of machinery have pulleys that move in relation to the power source, but they rely on spring loading to ensure the belt remains tight.

It all depends on what kind of power you need to transmit, and the type of belt you're using.
Normal V-belts don't need much tension to grip, whereas as smaller multi-groove belts require a lot of tension to grip.

Spring loading! Why didn't I think of that? Now I feel really stupid...

The original idea came from wondering how to build a table saw, then moved to "ohh what about a router table as well", before settling on the perfectly sensible idea to combine the two...



Realistically if I ever made something like this I'd be using a cheap saw/router from B&Q mounted upside down under a bench, but I enjoy working through these kind of ideas.

Normal V-belts don't need much tension to grip...

And for transferring power for this kind of equipment (saw/router bit etc) a v-belt should presumably be acceptable, I believe? Lathes tend to run on flat or v's?

Oh great. Now my mind just raced into overkill

Edited to add: Inspired by the old line shaft system for belt driven machines...
