Motorize my bead rollers
352-28187K.jpg
rotary former.jpgHi all, I'm one of the new guys. I did a search for motorized roller conversions but only came up with a thread that concentrated mostly on the Harbor Freight power drill set up. I want something a little less crude than that but I'm no master of electrics either. The two units I want to motorize are: Eastwood bead roller PEXTO type rotary style bead roller/former (see photos attached) I have a nice 6 amp foot pedal from a Husqvarna sewing machine (US current). I'm thinking about 14 inches for the top pulley wheel and maybe two inches for the small one. Prefer to use V-belt pulleys as I can get them for nothing at scrap yard. As far as motors, I'm not opposed to using a power drill as I have a vintage spare Milwaukee variable speed drill I could cannibalize. I have a small lathe so I can turn bearings/bushings ect.to fit the drive shaft or re-bored pulleys if I need to. Pictures of other conversions would help.

Thanks Bill,
That's the one I already saw & it's in the search files. I like his guide fence a lot and I'll likely may a similar one but I was looking for a set-up a little less 'home made' looking as far as powering the roller. JImmy

A couple Sheet metal covers/belt guards, and a coat of paint and nobody knows what's under there.... I just never take the time to do that stuff for my own tools... as long as it works that's all I need it to do.. It's the customers stuff that has to look nice...
But I know what you mean.. it is nice to have a professional looking piece of machinery in the shop when prospective customers walk in.... Luckily there's enough motorcycles in the shed that I can point to, to show my work..

You could use a small electric motor mounted anywhere, even directly on the shaft and a variable switch for your foot pedal and your all set. build a couple covers and racks for your dies, some paint and your in business. As for the smaller roller you are on your own. I haven't built one of those.

Direct driving the shaft takes a bit of horsepower.....1/4 horse will do it, 1/3 horse is better. Mine was a 1/15~ish hp with a 4:1 belt reduction and still needed a bit of help sometimes.
No need to worry about wizardry, just use a variable speed motor (or not). I prefer 90vdc myself. A 3-phase motor and a vfd will work too. More than one person has used a fixed speed motor.....just remember you can't slow down for corners or speed up for long boring beads. DC or the vfd option allow for easy reversing. Single phase motors do not allow easy reversing. A gear reduction is a must! Mine was 87rpm with a 4:1 belt reduction, resulting in 22~ish rpm at the dies......even with 2" dies, that is moving pretty quickly!
