(they're huge!!!). I'm thinking of cutting them just above the curve at the base of the rise and clamping the bits to the corners of the box. These corners are made of steel and are quite strong. I'm not sure of how to do this. I've got one of these from a dynamo light and it seems to do the trick http://www.sjscycles.co.uk/busch-and-muller-high-quality-aluminum-stay-fitting-bracket-bmd23-prod11215/
but it's quite pricey. does anyone know of any other bracket that could do a similar job?
this is the current extent of the trike build, nearly there!
Just a thought to make sure they're more secure, could you cut them, have them threaded and use a connecting piece of tubing. A bit like plumbing:
