Re: turret motor question [TANKS]

[Jeremy Caylor <jeremyandcurt-at-yahoo.com>]

Hmmm, with a spring loaded wheel on it, the belt may slip fairly easily (past experiance). I would say either try to center the wheel, or try a different way to drive it, such as chain or different belt type... I'll attach a pic of my turret mechanism, which works perfect. The main "pulley" was just a cheap one I made out of wood, and it works well for what I need it for. Its a little off (as yours is) but the adjustable v-belt is able to be tightened, and still turn the turret on the "loose" spot during rotation. I used a windshield wiper motor that my brother got from work, which is from a semi truck...

How strong should my turret motor be?

I am using a toothed belt drive.  The wheel on the base on my turret is off center by about 1/32 of an inch.  I test ran the thing with a 9 volt battery and it stalled out turning one direction but worked turning the other way.  I will be running this with a 12 volt battery in the tank.  When I ran the turret I could stop it with my finger if it didn't stall out off of a 9 volt battery.  Should I try to center the turret ring or should I just place a spring loaded wheel on it?
