Bow Tube

I was going to make a carbon fibre pole, but after much deliberation, I have decided to go with aluminium.
The problem being that with a bow tube of 95mm & a tube of 80mm OD, I needed to make a bush for the difference.I had some 100mm round waterpipe so I made a set of shims & used some of the blue PVC glue to glue them together. After a bit of adjusting i got a good fit & the pole slides in them.
With a bearing at the both ends of the tube the pole is a neat sliding fit.









This is the set up for retaining the bow pole. Instead of nuts I will get a couple of 12mm wing nuts.
