laurona12 Posted April 26, 2012 Report Share Posted April 26, 2012 I'm looking for 12v Electric motor for a pecker. It needs to be around 40-50 rpm - does anyone know where to get one - I've googled and can't seem to find any in the UK. Quote Link to comment Share on other sites More sharing options...

laurona12 Posted April 29, 2012 Author Report Share Posted April 29, 2012 My post of a UK stockist must be invisible then? Sorry - no it wasn't ignored. I should have provided a bit more info in my OP.The Farnell motors at £21.10 + delivery are a bit too costly for this project.

I was looking in the minature DC motors section, not the gearboxes where this model is located ! These motors would have been just the job at that price as well !

"Right boys, I need help with a problem with my pecker..." :lol: There would be a lot of giggling going on ! I am struggling to locate an 'off the shelf' cam/bellcrank to fit the motor shaft. The shaft is 3mm diameter. ANy ideas ? My father in law is an Ex-Rolls Royce engineer so he's been helping me - in fact he been making it and he has no interest in shooting. He just loves having a project ! Edited May 16, 2012 by laurona12 Quote Link to comment Share on other sites More sharing options...

He just loves having a project ! If it is a light load I would cut one from acrylic. You may be able to cut an M3 thread on the motor shaft and tap the hole in the cam (drill is 2.5mm for an M3 thread). Once you have fitted the cam, use a 3mm nyloc nut to hold it all in place. If you cannot thread the motor shaft you will have to find something with a boss and grub screw to clamp it on. In this case you could use a model wheel, gear or pulley. The cam can then be screwed to what ever you use. Some motors have a flat machined into the shaft to allow the grub screw prevent slippage. If you need something laser cutting from acrylic send me some details in a pm and I may be able to help. Nick Quote Link to comment Share on other sites More sharing options...

NickS Posted May 17, 2012 Report Share Posted May 17, 2012 I am always happy to help out if I can. My background is marine engineering but I now teach Design Technology (Systems and Control) so may be able to assist with electronics including low-cost PIC based control systems, mechanisms etc. I always enjoy problem solving and kicking ideas about - anyone local can meet up but advice is available wherever!
