Spindle sanding on the router table

[transatlantic]

So I know you can't just attach a spindle sanding drum to a router as it doesn't go slow enough. But I was wondering if you could use a separate speed controller to bring the speed down?

Would that work? or would there not be enough torque?

something like this :

No Chance

Can you explain why?

I bought a record bobbin sander because I needed (wanted) to.

Very disappointed. even at the low speed of this, its incredibly easy to sand a circular gouge out of any thing you apply to it. And I can almost count the revolutions on that. Trying to slow a router down enough.... uh uh.

Its my least used machine. I find I can sand circular stuff easier by hand.

This might be closer to what you want;

Yeah - I will probably end up just using that. But I really like the idea of being able to reuse the space on the router table, as opposed to the small area on the bench press (without hitting the post)

But I would like to know why slowing the router down wouldn't work.

I bought that kit recently for shaping a knife handle - worked a treat and good value for the money imo.

depending on the router, you could be talking about rotation up to 30,000 rpm.

A drum sander works best around 1,000 rpm. Slowing a router down to 1 /30th of its speed will not do it any good at all. Its simply not made for it.

What are you sanding? compound shapes? flat pieces? each has its own best method.
