Harbor Freight Tools router speed control

How to adjust your speed controller to go even lower than the factory settings.

Bang on man. 3 years later I just bought one and drilled a hole where u said and the adjuster is still there. Thanks

[@Say10198]

An 2 more years later I'm going to do the same lol. Is Todd still with us?

[@MrGrigs681]

I know this video is 9 months old but it is still helping people. Great job and thank you!!!!

[@integr8er66]

Thank you, just bought one of these, had exactly the same issue so I came to see if this was how it was supposed to be and found your video. Perfect information. THANK YOU!

[@sneakinguponit]

Thanks! This modification worked great for me! The screw in the rheostat/potentiometer is a slotted screw, smaller than a #1. Like the video I was able to dial down the speed of my tool to buzzing without spinning and adjust upward from there.

Thank you!!! This solved my issue.

I am building a mini lathe to make screw-in pins, turned down from setscrews. I want to use a sewing machine motor but some of the foot pedals won't let you vary the speed as much as you would like. I believe this will work, as I could adjust the potentiometer to give me finer speed control. Thank you for the information.

Im pretty sure you can still pop off the back and access this from a small hole in the circuit board itself without having to drill any holes.

Thanks for the info Todd. If I hadn't seen this it would have been crazy to bypass the old motor control board on my treadmill. I got lucky and got ine of these with screws on the back. 👍

[@Soldier1287]

The adjusting screw is on the bottom of the circuit board nowadays it seems. I just bought mine today. And i have to turn it all the way to the right to get the speed reduction I want

Plug in a bridge rectifier to the unit and your motor, and it will powers brushed dc motor .

[@TACOMASRT5]

What rpm does your grinder spin at?

[@jamesmartin3914]

off to HF

[@dale1956ties]

It occurs to me that I can very likely use my variac to get the same effect and probably with a better range and more precise control.

[@fredsanford336]

Who cares? This video isn’t about your fruity variac. Nobody is impressed
