Re: Ratchet block


 

Thrift shop aluminum ski pole. (Aircraft quality aluminum for a buck) Cut off the rubber handle, use electrical tape to shim the Universal Joint to fit inside. Drill through aluminum pole and universal joint together with bit that is a little smaller then spring pin to be used. Leave drill bit in pole and remove drill. Tap drill bit out, use spring pin as driver. ?(I also make a small collar of pvc pipe that I heat and slide over aluminum before I start, so pvc, aluminum, and tape wrapped universal all held together with spring pin.)

Tapered end of pole:
Shim tapper with electrical tape ( single width wraps) ?in 3 or 4 places to the inside diameter of pvc pipe. It should slide over snug but not bind with tape. The pvc pipe size should fit most of the way up the tapper of the ski pole. I heat the pvc pipe ( fire, heat gun, maybe hair dryer) and drive it the rest?of the way up the taper. Put on a cap. $150 hiking stick for around $8.?

At Community Boating in Boston they use what appears to be PVC piping for the tiller extensions in their Mercury fleet. ?









They still use a the rubber U-joint (purchased separately) to hold it to the tiller though.

The extensions are pricey, has anyone made or found a cheaper substitute?

The wood tiller works fine.? I really like the tiller extension with the rubber universal joint though.? I have a longer extension that I like when I'm racing alone.? When my son is on the boat with me, I find myself wishing that I had a shorter extension. I'd say that upgrading to the universal joint will make a much smaller difference than upgrading from the hook to a block for the sheet though.?
