New Trailer
Posted: Mon Oct 19, 2020 3:16 pm
Hi All and thanks to all who have given ideas prior to me starting my new trailer build. I have been progressing slowly as it is quite a lot more work making all the little bits and pieces but it is also very rewarding. I thought it about time to put up a progress report with photos and as it is a nice sunny day here in Tassie, so here goes.
First I cut the main side and front rails from 100 x 50 x 3.2 mm RHS and the cross members from 50 x 50 x 4 mm RHS and made and welded on the brackets to hold the keel roller frames. the main frame is not welded as yet. In this photo, obviously the frame is sitting upside down as its not put together yet. Then I cut the tow bar sections from 65 x 65 x 5 mm RHS. I used 65 x 10 mm plate to make the connection between the coupling and the tow bar. The back two bolts had to be welded in to place that hold the coupling and I had to drill an access hole in the side plate to be able to fit the hand brake pivot. The front two coupling bolts just bolt on through the base plate. Also fitted the new galvanised hitch Then I made the last three keel roller brackets which have 20mm spindles as well as 20 mm for the main spindle. As these roller brackets will flop down and sit on the cross member when the boat is not on the trailer, I will fit small rubber blocks for the roller frames to rest against and then not damage the galvanising. And purchased grey rubber keel rollers which are a bit longer between the ends of the dog bone to allow a little more room for the keel to fit them. Also, they are softer than the red ones and non marking Manufactured the hinge for the trailer tilt and the lock mechanism for the tilt but as yet have not made the back end of the draw bar or fitted the hinge to that. Have made up a kit for the axle including 9 Leaf,1900kg springs, 4 inch drop bars, new galvanised hubs, 45 x 45 solid axle and stub axles as well as new galvanised mechanical disc brakes and fitted the brackets to hold them on to the stub axles. The axle is not welded as yet, but what you do is to use a large piece of channel (I am going to two pieces of steel for the lifting frame ( 90 x 90 x 3.5mm )temporarily welded into a channel ) to sit the bare wheel rims in, have the hubs fitted dry and done up tight on the stub axles, then tack weld it all up. This way, you get the wheel alignment correct as it is welded with the wheels absolutely true, sitting in the channel. I will soon be ready to start assembling all of the above, its been a very interesting project so far and at the end of the day, should end up with a great trailer.
I spoke to the registration inspector, and as a result, once I have it completed the build, I will have it weighed before I have it inspected for rego, he will stamp in the VIN number and supply me with the compliance plate which I will fit to the trailer once I have dismantled it , had it galvanised and reassembled it.
Still to do, build the spare wheel carrier and winch post along with the tow bar fold out extension and various other brackets, etc
More photos to come, hope you found this of interest.
Cheers all.
