To limit sheet travel on RMG stepdown drum

I do not think I have ever read that this is an accepted way to do this, but it seems logical to me.

I am using a older stepdown drum than the current 32ZS6 stepdown drum so it gives me too much travel with 100% throw on the stick. This drum has more revolutions than the 32ZS6 before it steps down to the small diameter. If I limit the number of turns of the RMG, it seems like the fewer turns will cause the sheet line to never go onto the small part of the drum unless I start with about 3/4 of a wrap at full out. I do not want to have to do that.

It seems like the solution would be to drill a new hole in the drum for the sheet (with the stop knot) to go thru about 3/4 of a turn away from the current hole. Then I would set the end points for the winch to turn 3/4 of a turn less.

Has anyone else ever done that or what else might be done to limit sheet travel? Or am I not seeing this correctly?

Thanks

The RMG winch is programed via an on board chip. It makes setting the end points of travel very easy. You do not want to use the Transmitter end point adjustment for this winch. If you go to the RMG web site, you can download the manual and the procedures for setting up the winch properly....

Tom,

Thanks. That is good information for this discussion.

I now understand my problem and it can be rectified by using the current 32ZS6 drum. I still think this would be a good idea if someone is using an older RMG stepdown drum and wanting 16.5 inches of sheet travel with stepdown at closehauled.
