Default Router speed controllers

Has anyone used a speed controller and if so, is it helpful? Thanks for any wisdom as I am not very experienced with routing.

I don't have one but lots of members have. You can't use them is you already have one built in. If you get one make sure the amp rating is equal to or greater than what you intend to plug into it.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Don't have one, never tried one, for what I do and how I do it, never felt any need for one. If you can, I'd try one before buying, no sense in spending money without trying one first, and you may not like it.

I made one using one of those cheap modules off Ebay to use with my 500 watt AEG drill in a drill stand, It works a treat, prior to this if I wanted to drill any hole bigger than 1/8" in metal the drill bit would dance all over the place. I can slow the drill down to around 20% with it, but bear in mind that they do reduce the amount of power as well, so your router will slow down but also have less torque as well. The ones from Harbor Freight etc would use the same or similar circuitry.

I got this one and put it in a case (only do this if you are competent with working with mains voltages, you could electrocute yourself), it says it's rated to 2000w but I wouldn't use it for anything over half that, those pesky Chinese do fudge the figures a lot.



And as stated in other posts you can't use them with routers that have soft start, speed control or with induction motors.

I used one on my Hitachi MV12 router that the speed control had burned out. They work fine but you do notice a loss of torque at some speeds. I got mine at Harbor Freight for a lot less than the ones advertised in the catalogs.

I use one on both my router tables, wouldn't be without them.
The one is on a Bosch 1617 motor, and the other is on a PC 7518. I set the motor on high setting and plug it into the speed control. The reason I use them is they are easier to access in the router lifts than the speed controls on the motors themselves.

As a second-round newbie (I've been substantially away from routers for several decades) I have a question about speed controls. It seems basic, but ...

I know that a fair number of router bits specify a maximum speed. So the question is, with an add-on router speed control,

*
How does one know what the current speed is?


I know there are several ways I could measure it in static, no-load conditions. (Build a simple optical or Hall-effect tachometer.) But what about real world in-use conditions?

I go by the sound of the bit. I turn on the router with no load on the bit and dial it up til it sounds nice and smooth,no vibration, not screaming. The small diam. bits, will take the full speed, the larger bits will take a slower speed.

As Herb said listen to the sound of the bit. About the only time I find it necessary to adjust the speed is when I'm using a very large paneling bit. If it sounds like a propeller then it's going too fast. Don't put too much stock into what is given as speed for different size bits. With very little practice it will become second nature.

I've had a 1/2" makita router in my table for 4 years now. No speed control. never needed one so far. I've used bits up to 1 1/2" across with no problems.
I suspect 2" wide or more would definitely need speed control.
