Trailer frame rebuild Ep2 - Stripping it down

Once the trailer was clear i put it up on stands.

Then measured up and drew some dimension diagrams, so it could all be re-built to size again.






Removed all the fittings. The bunk supports, rollers and their frames, wheel assembly, winch assembly, the draw-bar and it's pivot, the A frames apex plate, the jockey wheel fitting.

Some things were held on by square U bolts (50 mm inside width) , others were welded on so cutting discs on 9" and 5" grinders removed these.

(NB - I have oxy acetalene gear stored - this would have helped, but haven't hired the gas bottles for years  as don't use it enough )

Normally with the boat on trailer, it's very hard to see all the parts hidden under the hull. So these photos reveal some of the parts that are usually unseen.

The draw bar removed from A-frame

Stripping down the trailer frame




Axle, suspension and wheel assembly




Disc brakes, leaf springs and drop axle




Brake lever , disc


A good sized "deco" floored shed and workshop area - the shed posts are made from swamp paperbark tree trunks with bark removed (They are quite rot and termite resistant when concreted in, kept dry and sump oiled at the base)

Winch post assembly

 I kept the frame mostly intact - so it can be used as a template/ base to build the new frame on.

5" cutting wheel on grinder - weld-on roller frame clamps removed.
Other frames had bolt-on roller frames

Trailer parts cut off - A frame apex plate, jockey wheel clamp, pivot frame for tilt arm

Bolt and nut to hold tilt draw bar (to A frame apex plate)

Tow ball coupling and brake actuator, brake lever - removed from draw bar and re-assembled.
Plan to re-use most trailer fittings on the new frame once built.
