WSI 2 tire rack (DIY edition), after a test fit with some tires in I realised that the hi-lift would not fit across the top of the back rail and still allow the cover to close. Looking around at the left over sections of tube from finishing/notching the rack I worked out that I had enough to build the small bar off the front of one of the sides. So I joined two sections (well a pipe fitter friend of mine did that weld) of cut off end to end, notched it and tacked it in place, then notched one of the smaller cut offs as a brace, tacked that, then welded it all in place with some pointers from a friend that works in race fab shops.
I already had the hi-lift 1-2" tube mounts that I wanted to use, so I cut some tabs from 1" angle to use as the mount points as the tube clamps would probably just slip round. Then I drilled the bolt holes, clamped them all to the new section of tube welded up the sides of the mounts trimmed them and the welded the back side (not that it was required for strength just looks).
Rack was then finished with rustoleum bed liner rattle cans. After paint the hilft mounts were bolted on using some fresh grade 8.8 hardware (I may upgrade this to imperial grade 8, as metric 8.8 is closer to imperial grade 5).
Today I think I will CAD up an end cap for the tube so I can print it on the 3d printer next time I go to the workshop, that and install the bolt covers that I printed for the bolt heads attached to the bed bolts.
