I have an old golf trolley and wifey has bought me a new golf umbrella.
Every review of universal umbrella holders seems fraught with negative comments so I wondered what I'd got to make my own.
Thus far I'm nearly but not quite there:
At the moment I don't know the best way to attach the system to the square section handle. I have a collection of old aerial fittings and the clamshell type clamp nearly works but is not wide enough for the waste pipe and is a bit too wide on the handle's 5/16" square section.
I've wondered about cutting a 5/16" slot in end of the waste pipe and pushing that over the handle but it will still need a secure fixing.
I would prefer to not drill into the handle unless no other option.
Most commercial holders seem to have adjustments for the angle/tilt and again I can't help think that the right aerial attachments could work, though I'm not sure why I would want to vary from vertical.
Anyway - I'm looking for some inspirational ideas from the collective of uk.d-i-y short of buying a whole new trolley/golf bag system in which these things are incorporated from the outset.
