Speed Control

[bennylaird]

These work well for the smaller routers, drills etc up to 1200W.

Has anyone found an inline 2400W speed control around? My Makita 3612 could use one.

Dick Smith have a kit

Timbecon and Carba-Tec used to push a Taiwanese made variable speed controller for around 50bucks don't know whether they still do ...I have one...bought at a WW show some years back for use with a fixed speed Makita router I have.

Cheers

Only hassle is the low power, have not seen one rated at 2400W yet?

The small kits of speed controllers are only rated to 3A - I use mine mainly on a large AEG drill - perfect - to use on a router use the DSE kit # K3087 - about $140 -$150 - a lot of $'s but rated at 10A and 2400W motors.
hope it helps,
Bob

Dick Smith have a 2400w kit, $143, available at the Werribee store according to the web site.

Use this on a router and you'll quickly burn up your $143 and the hours of assembly time.
We discussed this about 6 months ago. See

Hi Benny,

From some of your other posts, I'd suggest that you need a speed controller on your 'bikes :eek:

Yes, correct, it was discussed about six months ago but only opinions were expressed and as usual no hard facts as to the suitability of the speed controller were presented.

Ok, lets put this one to bed for once and for all, you F**k around with voltage, speed, wattage etc applied to a power tool and something happens your warranty is worth jack $h!t. In addition, because its an after-market addition you have no guarantee of what speed your tool is spinning. Hence you can damage valuable stock as well with no hope of recompence.

Fellow forum members, power tools have never been cheaper, and the quality of cheap tools is increasing.

Where is the value in spending $150 to add a dodgy speed control to a router you paid $400 for 15 years ago when you can now buy a brand new variable speed router for a lot less than that

Yet another OPINION without any FACTS to the speed controller in question being dodgy.

Someone who has used one of these speed controllers and can give an informed opinion please respond then it can be put to bed. Opinions are worth crap without the facts!

Exactly my point, you are arguing with me and agreeing with me at the same time. I was asking people to check that the speed control was ok before investing in it and also trying to say that the kits on the market may be beyond the average woodworker and suggesting that inbuilt. warranted and proven speed controllers may be better than taking a chance on after-market gear

Wrong.

It was you who used the word dodgy.

If you are basing your statement on personal experience then fine but to make a statement without any personal experience is a waste of time.

Too many replies to this forum are opinions which are not necessarily based on any facts.

Opinions are fine but of little use to someone wanting information.

Hi,
I have made two of the Dick Smith/Silicon chip speed controls, I use one for a large buff for polishing the car which had a speed control but lasted a day so i bypassed it and now use the one i made. It works on brush type motors only and has very good torque at low speeds. the second one i made i use at work to control the speed of an electric hoist, it had one speed and was too fast for the aplication and seeing as it was a brush motor of about 6 amps I tried it and it works fine and i can slow it down to a crawl. I would lift about 1/2 ton. It will handle up to 10 amps which is 2400watts and was easy to make.

Brushed electric motors are variable horsepower machines. You set the power by varying the supply with voltage, current and load. It's amazing what range they will function over and the main problem is heat either from to much speed or current.

These speed controllers are basically pulsed bursts of voltage (therefore current) which is variable in either pulse width or frequency. They are usually of better specs than the simple thyristor circuits included in the drill etc.

The cost is not $150 for the one machine as you can use it for almost any other use hence reducing the outlay.

Great for hot wire cutting of foam, faultfinding of equipment that shuts down with full power, heat control from a heat gun etc etc . Lots of great uses.

Still for most of us a forget it and use the fact that your old router is no good and get a new speed controlled router............................
