Jethros Model A update....Ladder bars

[Jethro]

Been busy designing and fabbing ladder bars for the model a. I basically copied P&J style but made swiss cheese webbing instead of a single bar or tube. Made the brackets from 3/8 plate and turned the threaded bungs and clevises on the lathe.....

Hi there this might seem like a dumb question but did you weld your brackets to the rear-end? or are they just bolted together?

Nice fab work Jethro.

.....damn, that thing looks bulletproof already.....those side rails -are they two pieces of 2"x2" or 2"x3" 'stacked'....?

They are just tack welded together to hold evrything in place until I get it all mocked up

Actually it's 2x4

Jethro,
That's fine looking work you do.
How smooth are your roads for ladder bar suspension ?
I changed my original ladder bar setup on the Studie in favor of tri-angulated 4 link.

The roads here are smooth enough :rolleyes:...yeah we got some doozy potholes too :eek: but mostly pretty good..:cool:

Their is a big difference between the conventional ladder bar set up and the set up Jethro has..Jethro's are tappered in at the front which allow the axle to roll especially when the have a rubber bushing in the front. The closer they are mounted together in the front the better they are...Where as the regular set up are mounted parallel and dont allow the axle to twist ,They just bind up and usually break....Nice work Jethro!!!!!

[N2RODDIN]

Lookin good for sure. Nice job!

:eek:bgbdlinc. The 2x4 main rails look like they are stacked but the line you see is the weld line .The tube is made by folding flat material and butt welding it.:DJethro is doing a very nice job .

...seen it but never used it, thanks Bob

[wessider]

frame and crossmembers look nice. your metal work looks very clean. i though of building my four link triangulation like the p&j style. Two many angle for my first suspention build. I went with the parallel setup. Wish i had your skill!!

keep posting your progress. It helps guys like me learn.

[CDNflatlander]

It has been said here already, but Nice Work! Some of the replies and the good pictures are giving me some different ideas for my A chassis.
Thanks for the post.

Nice work Jethro. What is that you used for the x-members?

Very nice set up all round there, good to see.

Jethro, I'm curious about what type of bushings your using on the front end of the "hair pins."
Are they the urethane type?
Will they impart a certain amount of resistance when the chassis "rolls" along the longitudinal axis?

I have been playing around with what are called "Johnny Joints."
They allow "rotation" in two plains, side to side (twisting) and up and down.
They are popular with the "rock crawler" folks; and claim a greater amount of flexibility. Plus they have a grease "Zerk" for lubrication.

I was at the Upholstery shop today and saw Jethro's wifes car in there.
What a nice machine.
Nice work on that car as well as the Model A.

When ya coming to breaky again?

I've seen those"johnny joints" in pictures and they look like they'd work good as a front connection for ladder bars or truck arms. I'm using energy suspension four bar bushings. They are just over 1 inch OD and have a 5/8 th inch bore steel sleeve so I can use a 5/8 bolt up front. The wall thickness on the bushing is only about 1/8th so there won't be tons of lateral movement but hopefully enough flex to not break things.I'm going to use a panhard bar too...

The crossmembers are 2x4 rectangle tube and and the "x" pieces are 2x4 that's been split lengthwise and drilled with a holesaw.

:rolleyes:Jethro I should have picked up on that splitting of the tube .The passenger side shows the join in the middle :rolleyes: Nice job Don't forget lock nuts on the rear of the link
