I have looked at a million different ways people have powered bead rollers and since I got a bad shoulder cranking the bead roller was not something I was looking forward to. Being as I try to be a frugal as possible I found the garage door opener method and and the rest of the junk to do it.
I had a garage door opener up in the attic of the shop that a friend had given to me maybe 15 years ago. I decided to use the chqin drive opener. I pulled the opener down and crossed some wires and it moved. I thought great when I tore it down It would not work I think the starting cap went poof.
So the wife had been following my plan and she heard me say I think the winch method would be better so she says "You have the small winch for your tractor don't you? I have a old HF 2000Lb winch I have it mounted to a sleeve hitch. I can use it to pull brush and on the tractor to pull small stumps, that is when I can find a good swamper to work for me.
So to keep this on tract I decided to motorize my bead roller with a small 2k winch. ie Horrible fright. Now instead of using my 2000Lb winch the Wife offered to foot the bill for this conversion and use all new parts.
Yeah man, when she is paying the bill I gets the frills.. Well not really she is frugal, sometimes to a fault but not this time
So I set about gathering a design and the various parts that I will need. All I have to get now is the sprockets but not having the winch rpm just yet I can't set a gear ratio. I do have a chain, "Thanks Mitch".
So the basic ingredients will be as follows:
Motor Source Badlands 2500Lb 12 volt DC winch. $68.00
Power sourse 9 to 15 volt DC output switching power supply $50.00
Speed control for DC Motor is a DC Pulse Width Modulator speed control. $35.00
1 double poll double throw 12 volt dc relay. Free
1 Double Pole single throw toggle rated 250 vac at 3 amps. Free
1 Horible frieght Foot actuated switch $10.00
This is the basic list of ingredients, I get asked "What is a Pulse Modulator" quite frequently so I have a lectrics 101 lesson.
When you hook a dc motor to a dc source the motor runs and runs at the same speed because of the voltage stays at the same 12 volts
Now put a switch in series with your dc supply. as the motor is running if you turn the switch off and on at say 2000 times a second the motor will slow down because it is no longer getting all of the current because of the time the switch is off compared to the time it is on is longer. If you keep the switch turned on longer there will be more time for current to flow.
This is a better method to control the speed of a DC motor.
Please remember this is boiling it down to a simple layman's terms not 100% explanation.
Parts have arrived so with the equipment list that I have drawn in conjunction with up a rough block diagram of this thing I am on my way.
First order of business is to tear down the winch and remove the winch drum so I can machine the drum for a sprocket.
I will pull the drum and continue on when I figure how to get it apart..
To be continued.
