"Spike Bike Racks" progress

These are a little further along, but this is the most recent pic of them fully assembled during a test fitting. They're all welded up with the exception of a few small additional supports along the base of the spikes. They're really solid, but I thought it would be better to be safe than sorry so I'm adding them. Grinding all the welds has been pretty tedious but that part is all done now so I can do my final finish sanding prep prior to getting them loaded up to go to the sandblaster then for a 2 color powdercoated finish. I'm still working on the exact configuration for the bolts since I want to have them locked into place and tamper proof. I've got a few options, but thought I'd do some more research first. Any luck they'll be completed and installed in the next week or two.
