Removeable braces
Guys,
I'm trying to confirm how removable tubular engine bay braces are finished at the ends,
My question is here http://www.desicodesign.com/brace.gif
Am I right or not?
Thanks,
Alan

When you say engine bay brace, do you mean an actual brace for the bay, or a brace to stabilise the engine?
I made a big version of the kind that is used on minis.
This is an engine brace type.
did this by getting two metal blocks for the ends, _approx_ 32 x 32 square and 22mm thick.
Get two big holes made in them to take the 'rubbers' from a mini stabiliser bar.
you can buy these in the states - www.minispares.com i think. although this site looks american, and has an english section, the bits I ordered came
from potters bar just outside north london!
these are easy to use cos they are in two halves, with a metal pushed tube inside. So there's no struggling to get em in.
One of these blocks and bushes are used each end, and they are joined together by 12mm rod. (screwed into the blocks.)
My engine, which was really floppy (tech term) is now rock solid - the engine barely moves when revved. I made a plate up that attatches to the top
of the type 9's box's two fixing bolts.
As always, if you need a pic, etc.....

Hi Steve,
Thanks for the response.
The brace I mean, that I tried to portray in the sketch, is used for engine bay bracing, and doesn't touch the engine. It's just a bolt-in piece
made of a piece of round tube. with round tube stubs at an angle at each end. Each end piece has some means of fastening, and it's that detail I was
trying to verify.
I believe that the same design is seen a lot in racers and track cars.
Cheers,
Alan

Some of the aircraft i work on have removable braces, they are formed with a forked section on the frame and a pegged section on the rod there
fastened together with large(1/2") pip pins.
hope that makes sense.

Hi scutter,
Thanks for that, good info.
However, I guess I'm not asking my question very well 
What I need to know is how this specific type of brace (shown in link below) is fastened at the end.

My interpretation of the joint end was here:

I was just asking is that how they are mounted/fastened or not?
Cheers,
Alan

im sure this inst gonna add mucj but....
the engine compartment brace on my mazda 323 zxi mounted between the turrets of the machpereson struts (a pain if you wanted to get the battery out as
its right over the top!) simply had metal plates welded to the ends of the rod which simply bolted down...
looks like you are doing something that needs to come out a lot or be elegant?

Steve,
The funny thing is I don't have a specific application in mind. It's just that I've seen the "tube with tube ends" brace used a lot (the new
westfield XTR2 has them holding the steering column) and I've often wondered what the end was like and I couldn't think of any other way than my
idea.

ive seen roll cages mounted in like ur drawing some with the boolt through the middle aand some with a plate on the short tube and then welded so if
its good enough for the msa scruitneers should be good enough for a brace on a locost.
also seen it used to mount the rear diff on a car linking it too the roll cage to give it more strength

Thanks for the confirmation. I thought it must be that way. Oh, and diffs too, I thought I'd it seemed familiar!
Cheers
