Hello all,
I've found some great write-ups on how to control 2 wheelchair motors for robotic projects, but a lot of what I'm reading is over kill for what I plan to use the motor for, so I need some help for a simple control unit.
Here is the plan I would like to control a wheelchair motor to operate a stationary archery press. Here is what it looks like

What I would like to is control the press with a foot pedal hopefully a forward and reverse pedal and off when the pedal is not in use. I am interested in having the brake applied when the motor is not in use.
I'm not concerned with increasing or decreasing the speed each time with the foot pedal but I would like some type of speed controller to adjust the speed to get the right speed set for the first couple of runs so that it is not to fast as this press is normally hand operated. The load on the jack will range from 70 to 300 pounds, I feel the wheelchair motor will have enough torque but I do think circuit will require handling high amps as it will be a load to press the bow. I will be able to make all the couplers for the motor to jack connection and it actually has a place on the back of the jack to do this so that in case manual operation is required I can still use the detachable handle in the front. This is one reason I chose the wheelchair motor I can use the manual release to operate the press manual. I also wanted it to be quiet operation as I have already hooked a black and decker 7amp 1/2 ac drill to the press to see how it would work, it did fine but was loud, not constant on the speed, and had no brake, but worked as a power motor for the press and pressed the bow just hard to use daily.
I plan to get a AC to DC power supply to run this as it does not need to be battery operated.
At this point I have wheelchair motors 3 sets that were salvaged from running chairs, but I'm open to suggestions if you know of anything better for my application.
Key points are forward and reverse foot pedal, the motor stop/brake when the power is removed, speed adjustment so that the rate of pressing can be set to a safe level(full throttle would be uncontrollable) but once adjusted it would be left there, an AC to DC power supply that would handle the amps and supply the volts need.
All of this can be wired as there is no need for remote operation.
I have developed a cramp from pressing bows by hand and really need this to make my daily life easier. Yes there are other brand powered bow pressed but the versatility and durability of the xpress is what I need.
I'm fairly mechanical minded so I can follow instructions and simple schematics I just have not found tons of info on the wheelchair motors and what I have found refer to robot projects so I'm reaching out for some help from you guys to see if this can be done. I'm willing to purchase components so not looking for circuit creation but more or less an off the shelf parts to DIY motorized X-press.
Any help is greatly appreciated and thanks in advance.
