So, it's not as large as the one referenced in this thread, but it will have the ulock holder. It'll be supported from the upper fork eyelets and from brackets on the handlebar.

I've done a lot of projects with copper pipe, including a basement picture rail that has no issues with 7lbs+ guitars hanging from it. So, I'm not worried about strength. The weight will be a bit more than aluminum, but that will counterbalance my rear-heavy bike with an internal-hub, rack and usually fully loaded panniers.

Copper isn't THAT expensive. You can get 1/2" three-way tee fittings on Amazon, 25 for $14 and that's most of the material right there. I already have those and a lot of leftover lengths of 1/2" tube as well, but I would only need to buy less than $10 if I didn't. I have the elbow fittings already but they aren't as expensive as the tee fittings. I don't have a torch, so $8 more for a JB Weld (epoxy). So, this would cost about $40, if I had to buy everything. This assumes you have a cheap pipe cutter or hacksaw already. However, I already have most of the parts so this will cost me about a few bucks and I'll be able to custom fit it to my bike. I simply couldn't find a rack that connects to the upper fork eyelets, has a ulock holder and mounts above my existing dynamo powered headlight which occupies the fender bracket. I'm really into re-use/re-claiming/ re-purposing and I think it will look pretty cool.
