design for rear bar

Post by physh »

Hi all,

Does anyone have any CAD drawings or similar sort of thing for how to design a rear bar with twin wheel carriers?

If it was for a solid axle 100 series that'd be awesome... but I don't really mind modifying / doing my own.

Lots of people have been making their own, and I think it'll be a good learning project with a mate who actually KNOWS how to use a MIG... I'll learn something! :)

We'll be taking our own measurements etc, but wondering as to design and how best to strengthen the various areas.

Things like how do we strengthen the outer wings, and corners so as to support twin 33" tyres?

We will be making the bars out of steel, but I dunno what type, guage, or shape is best to start out with... :)

I have done a bit of a search, but not come back with anyone who's actually put up a design... so any help would be appreciated! :)

Cheerio

Hey Physh,

I don't have a drawing, but I am in the process of designing a new rear bar for my 40. I was going to set it up with twin wheel carriers sounds like great minds think alike. I was also going to making one side interchangable with a jerry can holder.

I think i will start with at least 4mm minimum mild steel and use cross braces to stiffen it up. I may even just go with 6mm and be sure. I was going to modify this one a bit to suit what i want.
http://web.mac.com/troyraven/iWeb/Proje ... 20Bar.html It seems like a good starting point.

Are you planning on adding a towbar? I am not sure if a towbar requries an engineer certifying the design, I would assume that it does.

If i get around to CADing it up in the next week or two i'll shoot you a copy.

Cheers

Muz
