I took this during our ride down to the RTE at Ashbourne in Mid January and the extra weight in the trailer plus the Esky and contents didn't appear to have much effect on the bike and there were no issues with handling either.
On Saturday evening I cut the angles for the sides.
To secure the front piece in place while the holes were drilled requires precision mounting hardware. In essence a variation of what I used to do when I working in an automotive metal press shop to mount some dies (tooling) into a press.
The angled piece is just forward of the plate and in centre (+/- 1 mm)
and got the front piece in place but my cordless drill ran out of steam and I couldn't do any more.
This evening after borrowing a proper (one with a cord) electric drill I finished the front piece and riveted it in place.
Then it was time for the RH side and unlike the front piece would mounted under the plate. The front rivet hole will be drilled when the other holes are drilled and the piece riveted in place.
The holes were drilled in the plate first, the angle held in place with a couple of clamps, and the rear hole drilled and then riveted. Then the remaining holes were drilled before removing the clamps and then riveted.
The remaining front hole was completed next. The rear piece is in place ready to be mounted but I may need to use it for helping to hold the LH side in place while drilling the holes. This piece was supposed to mount underneath as well but it's a little to wide to slide in between the draw bar so plan two is in force.....lol.
This is an idea of the finished product. The LH side if plate is going to have a piece cut out which will allow the Esky drain water a place to escape. I normally recycle this water when at camp and use it for washing up dishes, shaving and/or giving myself a wash and even the bike a debug after a day on the road. The little metal piece in the centre is underneath the Esky drain hole and I need to borrow a jig saw to cut this then it's a repeat of todays effort to mount the remaining LH side.
