Motorising a bead roller (again)

[mike 109444]

I did have mine all set up with variable psu, two foot switches (one for forward and one for reverse)can't find any pics though !
If I recall the power draw under load was less than 8 amps.
Note again if I recall the speed at the bead rollers was , 5 rpm.

ps
look up dc motor control with"H bridge" switching (think that's what I used with the two foot switches)

I used a small (0.3kW) motor, gearbox and VFD wired through a pedal with a pot and a switch to give me forward and reverse with speed control.
It worked ok but was gutless at low speed so I added a chain drive to get the motor speed closer to 1300 revs at the max speed I wanted and it now works well.
It has more power than I need and will put a bead in 2mm stainless.

To my shame I still haven't put proper guards on it.

I watched several bead rolling videos last night, and this one stood out as running at a good speed for one man operation, he does not have a speed controller, I think that to keep it simple I will attempt to gear mine down using chains and sprockets, then just a simple reverse switch and an on / off foot pedal, electronics are not really for me...... I also think that my wheelchair motors have a brake, probably on until power is applied, If I don't keep it simple it will end up like a lot of projects, unfinished!

Some good stuff there.. Needs to know his convex and concave though..

I’m sure I’ve seen people use sewing machine motors and pedals

They might use the pedal but I doubt the motor is up to driving the rollers under load.

Wheelchair 24v motor / gearbox, sprockets / chain from under bench, it works, bit fast on 24v but spot on using 12v, maybe I will get a larger sprocket or just try running on 12v for now, when I get better at bead rolling I may want the extra speed from 24v, ignore the Christmas lights, I had three big boxes of old led tree lights to dump for the Parish Council, well let's just say that I now have "new" lights on my house and having black cable they can stay up all year without people moaning!

^ Interesting, I have a similar manual bead roller and have thought about motorising it. The trouble is, that would mean having to leave it set up somewhere, and I don't really have space for that. It lives on the shelf under the bench at the moment, and is put in the vice when needed.
