last year we attached a steel rod to the end or the drill transmission through a clamp thingy with the pins.. forgot what its called
this year, do we do the same thing?
the guys that attended were saying something about threading some sprockets and using the reverse screws to keep it on.. well, the only sprockets we have are the ones with the separate "hub" which we screw on to tighten against the rod... and the holes are not good for the end of the motor transmission...
so did we forget to recieve some special sprockets? or do we go the same way we did last year?

You are defiantly at a disadvantage not having attended the workshops. here is a quick review:

New this year are new drill motors. NO they do not mount to the shafts with a coupling like in the past. The sprockets are threaded and go on the end of the motor a special washer and left handed special screw is then used to secure the sprocket.

New this year is the way to mount the drive motors. You will need to fabricate a clamping system to use the boss on the drill motor as the clamping surface. We had two types of simple mounts at the workshops and pictures are posted.

Please read the rule over several times as these are but a few of the changes.

i have seen the pictures posted. thank you.. looks alot easier than last year
and you havent answered if we were to recieve some new "special" sprockets for this.. because we dont have any now... and does this mean we cant mount more than one sprocket to the motor? last year we had clamped two sprockets on.. is this no longer possible? and if we are to recieve "special" sprockets, how many teeth are they? so i can start thinking about ratios... and this washer you are talking about... is a plain one bought at home depot ok?

When you were given the New Drill motor (some teams are getting them shipped) the sprocket was mounted on the drilled. This is the only sprocket that will mount on the drill. The sprocket is 9 tooth. Mounting additional sprockets or using the drill motor as a direct drive would not be wise as the loads on the unit would damage it. There are many other possibilities using the supplied kit sprockets, remember you must use the kit sprockets.

The washers are "Special" in many respects. First they are the correct hole size and outside diameter as not to interfere with the chain. Second they are Hardened steel. Regular washers will allow the screw to "pull through" very quickly.
