Someone said this was going to be welded to the bike frame not bolted.

And someone else said that was a bad idea. Maybe that someone should have said 'a fucking bad idea' for additional emphasis.

Hey, fun fact: if the surfboard extends forward beyond the frame and parallel to the front wheel it may limit its movement...could result in a negative outcome...
To avoid that the board and its carrier would need either quite a lot of offset or have a lot of surfboard sticking out of the rear of the bike 😃
If the solution involved a third wheel (as in sidecar) it could carry the canoe just as well 💡

Is it definitely not an option to jack it up and carry above the rider?
No idea as not into bikes.

I suppose it's possible but ask yourself if you've ever seen anything like it and imagine you're the copper watching it go by.
I'd also anticipate a perhaps unfortunate aerodynamic effect.
And come to think of it, that will probably be a thing if the board is carried (as I imagine the idea to be) side on.
And that's another plus for the sidecar concept - convention.

Maybe the surfboard should have a motorised subframe capable of doing 15mph and handlebars. Is there a length limit for electric cycles?

That makes more sense...hmm. So to replicate those tubes wot I would say you need is some stainless pipe and the associated 45° and 90° bends. Also a bloke capable of welding stainless pipe into weird and heretofore unimagined shapes.
You, my son, should visit a custom exhaust shop.
You could theoretically learn to weld pipe yourself but I understand it's not the easiest task to start out with.
Polishing non-polished stainless steel is a reasonably rewarding activity in the technical requirements versus achievable results aspect (exhaust pipes as purchased from the vendor are typically unpolished).

I think it's all good apart from the potential swivelling issue at the back. Key clamps are strong and the tubing should be more than up for the task. a 90 degree elbow clamp is only £2.47 and does the same job as a bend. It's all galvanised. Stainless steel would be an expensive indulgence, especially if a specialised fabricator gets involved. It will only be on the bike when I take the board out, it will be indoors otherwise. Probably under my bed, bit of room there.

Probably less than you imagine but whatever.

A few bits of solid round and a big pipe bender hired from the tool shop?

The rack itself is simple. It's getting a good fix to the bike that needs thought. Talking of which, another light has just come on

The light that has come on: At the rear, scrap the idea of the single lugged bracket key clamp and the possibility that it will swivel with the weight/ going into a pothole or something.
Instead: Get the local welder to weld an 8/10mm nut into the centre of one end of a length of tubing. I can then simply bolt this straight through the hole in the lug in the bike's frame. Then form the u cradle for the board with key clamps, straight off this length of tube. Not the best aesthetics but simple and strong. That will do me. The lug on the frame just happens to be at more or less exactly the height I'd like the bottom of the surfboard to sit. Happy days.
We get there eventually. Just need to speak to the welder now. I understand that welding to galvanised steel is a big no no because of the toxic fumes given off. If so I can get a length of mild steel instead. Welding a nut into the end of a piece of tubing, it being important that it's fairly square, seems pretty difficult to me but I'd imagine an experienced welder would know some tricks to make this pretty simple.

The various key clamps and lengths of aluminium/ steel arrived today. Not to my house but a random one further down the hill. Common problem this, couriers can't be bothered to find the right address.
Anyway: I've put the front support together and it's great, solid as a rock It doesn't stick out beyond the legal limit but there's plenty of room to get my leg down. I need to get a metal plate welded to a length of steel for the back then the job will be complete. The local welder owes me a favour so it should only cost me a pint or two.
I'll try to post some pictures. Is there an idiot proof way of doing this on here? I say idiot proof because I really am a technological idiot.
