Rib trailer home build

[Sonar]

Any member made there own rib trailer on the forum .?
What size did you make.

[BogMonster]

I didn't make it (the first owner did) but the rib I just sold had a heavy duty home built twin axle trailer, I have various photos of it if you are looking for inspiration.

I am indeed a twin wheel is what I was thinking on.

Search Bedajim's posts for pics of his rather clever 'home' build.

Sonar i received some sound advice from Bedajim and some excellent pictures of his masterpiece. As I was restricted by only having a chop saw, angle grinder and arc welder I opted for a simpler design. I went double axle as I want to take the boat to Dubai and Mussandam to dive on ship wrecks and a lot of the launching here can be done by tractor with 25 foot pole extension on the front. Finally there are plenty of good second hand tyres about as they are changed after 50,000km on most cars due to effects of the sun. The double axles are built onto a bogey that can be moved fore and aft to get the nose weight of the trailer right for the tow vehicle. Once positioned it is locked in place with U bolts. The trailer has central rollers and bunks and can use a normal trailer boar for lights etc (however there are no rules here regarding trailer lighting). Best of luck with your plan; I know that you will get plenty of support and advice from the site users.

We don't all have access to Argie Howitzer bogies prime for adaptation.

This is the trailer I built for my 7.5m rib it has drop axles to get the hull lower to the ground/water.It also has mechanical disc brakes on the front axle.

Real nice looks like a good trailer.

Many thanks

Here you go.

Obviously it would be necessary to modify it to make it UK road legal (you might want suspension, brakes and lights for starters!) but the basic design of the trailer can be seen in the pictures.

Not at all in the same league as Bedajim's trailer, but what it provides is a very strong trailer (it has been used off road by other owners and will be by the new owner) which supports the boat very well off road and on rough roads - it has full length keel support and the bunks lay flat against the hull so it's about as good as you could get in that respect. It means it needs a steep beach to launch on, but there is such a beach exactly where I launch anyway so it wasn't a major problem once I got used to it. Smaller wheels would have reduced the depth needed - it had 7.50x16 Land Rover tyres fitted. It also had an extending drawbar - the hitch was mounted on snug fitting box section slid up inside the main spine of the trailer and retained with 2 x bolts through horizontal holes. Take those out, and you could pull the drawbar out about 6ft to get the boat further into the water, though I never used it.

It is based on old Land Rover hubs and stub axles welded onto the axle tubes so the wheel bearings are cheap and easy to get and pretty heavy duty as well. I think the spine for the trailer is made out of the leg that holds the roof on the side of a Portakabin, and the towing ring was a NATO 76mm eye off an Army trailer. The centre bunk is covered with old rubber conveyor belt out of a quarry crusher and I think the side bunks were heavy duty ex military fabric fuel hose. Mudguards also made out of conveyor belt.

No Argie howitzers used anywhere to the best of my knowledge

There you go, easy peazy. Made from materials readily available in any warzone.

I really like the nose snubber on this trailer. Custom to suit the bow.
Great idea.

Damage proof mudguards another great idea.

I just splashed the nose snubber off the rib while it was upside down and lined it with carpet.The FRP is about 6mm thick and about 9mm around the hole for the winch hook.
The poly skids on the trailer are very low friction. If I was to release the rib at the top of the ramp it would slide off onto the ramp.

I thought about it, but by the time I had bought all the running gear, fasteners, rollers etc and got it galvanised, it was going to be about another £50 for someone to build it for me!

Needless to say I put the order in for a new trailer!

Many thanks for the information I will be using this idea.
safer and better than a small rubber snubber.

My trailer cost about AU $3000 total to make,It would have cost about AU$ 6-7000 to buy from a manufacturer.Not a bad saving. I did have a mig welder and metal cutoff saw already.

I have the stuff to build it just looking about now for all the makings.
Hoping its not going to be to expensive to make

Still see how we go plenty of time to make one yet and no hurry to do it..
