It's hard to be sure from that pic, but it sure looks like that shockie has spherical bearings. IMHO these are high maintenance when used in our long distances in dusty/muddy conditions as they are not sealed.Quote:

Those set ups are similar to the Macpherson strut ? thats what first came to my mind when i saw them.
I think the best axle i ever came across is the AL-KO axle. no springs or shocks only the rubber bush. We have had a camper for 25 years with the AL-KO axle and its never had any maintenance and still works as good as the first day we got it.
They work really good under load.
Air spring should arrive Friday fingers crossed. They sent me an image before they packaged them up.
I got myself a rear end (complete) out of a Range Rover. We decided that the rear would be easier to work with for the purpose we need.
Getting closer to a start.
The air springs arrived, picked up the rear R/R rear axle.
We will start stripping the axle down this week, now i'm having trouble getting hold of the 2" Chromo for the arms.
The parts that need laser cutting goes away next week :)
I'm getting excited
Cheers
Not that I have been involved in the use of chromoly but from what I have been informed - unless you have the perfect welding procedure that maintains strength in the HAZ you may as well just use seamless tube and a boring weld
Less bling though ;)
Those short arms on your trailer design could be made of cheese and would probably still hold together!!!! 50mm chromoly - well - just wow

Yep, it cracks. Without checking, I think its meant to be post heat treated also. I'd use mild steel, but each to their own.
Here it is: I know a lot..... anyway, here it is.

"I'd use mild steel,"
I must be tighter than you Simon 'cos I use not only mild steel but last time I checked nb32H has a seam down the inside ;)
my theory is its still stronger than a landy rear arm and on a trailer has tonne less loading - it works and makes bushings easy
Witchdoctors trailer is gonna be flash! I cant wait to see it built!

If by chromoly you mean 4130, then yes it can crack after welding. It's the 0.3% carbon content which means you need to use a low hydrogen method.
I would use RHS/SHS for your links instead. Strength is close to 4130 (typically 350MPa yield for SHS/RHS) but the low carbon content means welding is much less involved.
Which end of the coast are you? There is Gold Coast Laser in Ormeau, and All Plates in Molendinar. I have used both multiple times and would recommend either.Quote:
