Hi rtciv,
Sorry for hijacking your thread, but as were working on the same kinda project I dont think you'll mind to much?
Done a bit more work to my mono hitch today. Iv'e got some aluminium angled plate that you may have seen me use on other trailers? I drilled 4 holes in plate and used a couple of clamps! (think there used to bolt satilight dishes to walls?) to secure the angle plate to my hitch. Drilled another couple of holes in plate for trailer frame then bolted it all together. I haven't put my grey box back on yet as I cant just yet? - The bolts that clamp on the hitch stick out a little bit much to slip the box on. I may have to drill the box and clamp through it.
Attached to bike - need to trim bolts down a bit.
Hitch attached to frame - I can get a good 45 degree turn but I think with the box on it will be reduced due to the box hitting the hitch.
Clamp Bolts - You can see from this picture how the bolts stick out into the frame area where the box will sit.
Full Setup - Took a few pics but this was the only half decent one that turned out. Will get a few more taken.
Still a bit of cleanup grinding to do and a fresh lick of paint. Yes (I KNOW) theres a BIG gap between hitch & tyre, its just the way it worked out. Also the hitch is not welded up completly square! but it'll have to do for now.
I found an old ironing board, the legs are bent about right I may get my mate to redo the hitch - We'll see.
Regards
Tom
