Do you think that this system will be strong enough to support a arm that can reach to the top peg and weights around 30 or less lbs? Is it overkill? Thanks.
On 330, we put our mast back a few inches to allow room for a big sprocket at the top. http://www.chiefdelphi.com/media/photos/27675. We use 2x1 1/8" for the mast, which is probably overkill.
