Bored the other weekend (rear beam triangulation).

My friend Ali (16valver) suggest i post this on here for some criticism

Been thinking about making one for a while and testing any difference and have had the excuse of spare time waiting on parts for the rest of my shell prep.





Fell free to move it if i have posted in the incorrect thread

 

Looks nicely fabricated, as for any performance advanage?? im still not convinced it will outweigh the detrimental effect of the increace in unsprung weight.

 

Good work goof - you boys are busy north of the border - looks very tidy on the welding indeed

I'm planning on making one for my Mk1 somewhere down the line. IIRC, I think I've bought 3mm steel for the inverted towers and centre bracket, though it's ages since I made up some cardboard templates, and it's in the back of the shed. M12 rose joints. I've yet to run through in my mind what level of support hides inside the inverted towers for the main rose joint bolt.

What plans have you for the tank type and location, now that the bars pass through the area?

My only other thought was (IIRC) the works beams had the tower attachments canted over slightly

... just to centre the rose joints within their travel, but I guess you haven't run out of travel so just a detail aspect?

Be rude not to put up a comparison with the works 'daddies', so here:

 

looks abit low to the ground to me ? top work tho been thinking about this for a while also

 

Saw this tonight and the fabrication is top notch.

Hoping Goof can build me one too...

 

Yep top work. Im impressed Goof. It does make a huge difference when running slicks as you are putting a massive load through the rear axle. I have this done to my MK3.

 

Nice. Is it for a mk1 or 2 ?

 

Very nice bit of fab work there.

 

And I love the axle stands

nice work

Thanks for the comments.

As for the the increase in unsprung weight i really doubt a few hundred grams a side will make a noticable difference.

gillm its not any lower to the ground than the works beams that chris has posted up, i already had this conversation with Ali last night It'll just be a different perspective as there are no stub axles discs etc to get a visual scale from at the mo.

Its for a MK2 more of an experiment at the moment. I also notice someone has posted up my c**p build thread

Lastly Chris the fuel tank that will be getting fabbed up will sit just under the wheel well which is now flat so a flat tank to try and lower some weight and i dont particularly want a tank behind me in the car.

 

goof no-one can hide anything on here , i can remove it if you like .

Great work there mind so wouldn't call it crap .

 

^^ No yer can't - I haven't read it yet

 

there you go

 

Don't suppose you'd be interested in making another one would you?

 

Need to test my own one mate which is a while off yet sadly

 

Nice work

This is on my list of things to do. Making it doesn't look too bad, its the moving of the fuel tank and exhaust thats delaying me doing it.

 

what diameter and wall thickness are the tubes you used?

 

Works spec was M12 rose joints. Add threaded inserts to weld inside a tube - say 2-3mm walls, so the tube ID has to be in the region of 16-18mm. Plus wall thickess (2-3mm?) = 20-24mm OD tube.

IIRC I've got 25mm in the shed.

Could have gone seamless, but I just bought seamed. Struggled to see the point.

 

do you have to weld an threaded insert in? could you not just tap a m12 thread into a smaller tube?
