Well after much deliberation and a poll (http://www.aulro.com/afvb/camping-tucker-bush-basics/84599-tinnie-transport.html) to decide how to transport our tinny as well as the camper trailer. I decided to modify my existing roof rack to take a bolt on boat loader. I had two weeks holidays - should knock it over in no time ... B) ... so I thought ... :unsure:
The design is based on the Custom Boat Loader, Rhino boat loader and Tinnie Tosser designs. I think I have taken the best of each and put them into mine.
So here it is so far.
I started by machining some threaded inserts to weld into the existing rack to bolt the loader to.

Then lay out a basic frame.

A bit of a mock-up to sort out roller positions

The motor and gearbox assembly I ordered arrived but instead of having the 120W motor I wanted, I was given a free upgrade to a 500W motor. It was huge and required nearly 60A to run it. Too big for what I needed so I sent it back ...

After a couple of days of machining delrin bushes and cutting end plates for all three rollers, the front roller was fitted.

Then the rear roller ...

And now the new 250W motor (still bigger than I requested but I can cope with 30A) is fitted up.

Next job is to fabricated the carrier for the bushes on the motor end of the main roller (I've already machined up the drives with internal key way) and then fit the outer carriers.
While I'm doing that, I'm also sorting the wiring and switching out. I've purchased a remote control unit from China (http://cgi.ebay.com.au/RF-Wireless-Electric-Garage-Gate-Door-Remote-Control-6R_W0QQitemZ350215153666QQcmdZViewItemQQptZUK_Home _Garden_Doors_LE?hash=item518a732802&_trksid=p4634.c0.m14.l1262) that arrived yesterday I've worked out how to drive the relays that will switch the motor.
So it's all coming together. Still a lot to do before it's ready to be tested. I hope to spend at least one more day on it before I have to go back to work on Monday. I'll add photos as it gets closer.
