Question to the pro’s. Would a variable speed router, where the variable speed does not work, and the RPM’S are a constant 22,000 RPM, could I use a variable speed controller to reduce down to a 550 RPM. Is this router considered a soft start. Would I have to remove the control board within the router it self, even though the variable does not work. Help!!!

(Not a pro) but almost all the VS routers have soft start and those speed controllers are supposed to be bad ju-ju for them. If it were mine, I’d just stick with the one speed and plan on adding another (different make) router to the shelf in due time.

I agree. Just use it for smaller bits and if you need to do some panel work, get a new, fixed base and mount it in a table.

At least is stuck at a very usable speed for 97% of most peoples work.

Are you sure the variable speed can’t be fixed?

What’s the router? If it’s one of the better brands I’d get it looked at.

I have a couple variable speed routers and use them for larger bits where I plan on taking a lot of wood. Slowing down a bit from 22,000 to 15-17,000 can make a big difference.
I have found that the speed controllers, at least the ones I have had, not only cut the voltage but also the amperage so the whole router bogs down. Hence, they don’t work very well. The little circuit boards in the routers help against this so you maintain the proper torque when slowing down a router.

Unless you are an electronics person, or can buy a replacement board, I would not try to fix it. I would consider getting it fixed if you use larger bits, and the router is expensive, like one of the larger Bosch’s.

Almost all VS routers are soft start as a function of the VS electronics a plug in speed controller would either work poorly or not at all. I hope you meant 5500rpm and not 550rpm as no router would have enough torque to spin anything going through wood at that speed. Most VS routers will only go down to 10000rpm, any slower and they don’t have enough torque, you would need a shaper if going any slower.

Have your say...
