Strut Brace

[davrian]

Can somone post a piccy of the brackets for a strut brace as I'm going to fabricate one. I'm also thinking of a triangulated one like the silver duck tail at Snett. Any opinions on the additional benefits?

Hey Ian,

How's it hanging?

Strut brace design is already here on this forum.

See:

Thanks to Peter Bull.

Make me one while your at it?

The main idea of the strut brace is obviously to keep the strut mounts in place. There are three different types, or basic designs, of strutbraces. Below is a sketch of the three.

 

 

The most common is the one to the left. It has a hinge in each end which makes it very easy to mount and you can add some tension in it to increase static camber. Whether that is good or bad I don't know, but I woun't do it. Since it has hinges all it does is transfer load from the outer strut mount to the inner.

 

The type in the middle has fixed mounts. The good thing with fixed mounts, IMO, is that it resists bending thus transfers a little bending moment into the bar. This type is therefore a little stiffer than the previous type.

 

The last type is the triangulated one. Since a triangle is statically determined, or stable, it does not need to have fixed mounts. The diagonal does that job through tension or compression. This type is the stiffest one, but it also adds most weight.

Thanks for the replies guys. It will be the triangulated one then. Easy to fabricate and easily removable for use of the boot.

 

What I don't get is the prices. Rosejoints are about £5 each and if you use thin wall T45 seamless tubing it is only slightly heavier than aluminium. Also you can use thinner guage due to the triangulated loadings. So the component parts probably add up to £25 with the coating additional to that. Mr Mig is going to see some action over the winter.

 

PS is you want non standard parts use the stock car and grass track manufacturers (Randle Mororsport etc) rather than Demon Thieves. They and their customers have a grasp on reality

It's called a pound to do the job and ten for knowing how!

 

Perhaps we need a reference section for designs, so IB'ers can get these things fabricated. I can supply a design for a harness bar, because they are a complete rip-off when you see the price and see the product!

Edited to say: Sorry, should explain that better - I'm not suggesting a rip off of, say, a Brey Krausse design. I have a design for a Harness bar that I came up with and I wouldn't want to advocate infringment of copyright.

If it's strut braces then put them in suspension. Roll cages, seat rails, harness bars etc go in interior and so on. Have just had a sort out of the tech boards, with a view to maybe adding a Trackday Mods section if required, but I don't think we need it.

As ever John, you're far too organised!
