These guys are pretty good.

As I read the above I was just about to recommend these chaps

Call them they have better discounts over the phone

Why silicone, ordinary ones are cheaper and last really well if you buy a recognised brand.

Not sure really, silicon sprang to mind as one of them has to go fairly close to the exhaust out the back end. That's only one elbow though. I'll look into rubber, see what the difference is in price.

 

[Morrisman]

Just had a look at rubber elbows, and they are 1/3 of the price of silicon. However the ones I've seen seem to be fairly tight bends, where something a little less radical would probably flow better.

Just found these on another web page, and I'm pretty sure they've got something wrong.... It has to be a typo as everything else nearly that size is a fiver or more.

Bends in ali, then use straight rubber connectors?

I've got a series of straight lengths that need connecting, so flexible elbows seems to be the simplest way to do it. I've no way to bend light tubing more than a few degrees, or it could be a lot less complicated. My pipe 'bender' is more suitable for crushing tubes than bending them.

Just had a quick google

£15+ for a 90 degree bend carry on as you are

I'm wondering whether to order a dozen, at 59p each what's the worst......

 

[slim_boy_fat]

at 59p each what's the worst......

Worst could be that they sting you a ridiculous figure for delivery. Check their site for delivery costs.

I decided to go for regular rubber bends from Car Builder Solutions.
7 rubber bends, 2 silicon bends, and 20 hose clips..... the wrong side of £120



I've made some 1/8" alloy brackets for front and rear support of the cooling pipes, just need some grommets to stop chaffing......however nothing available in 38mm 1 1/2" bore, so I'll slice some small bore rubber hose open to run around the edges.







The rather expensive imported thermostat housing come hose adaptor for the motor end of the cooling system happened to point the hose too close to the frame tube, so I shall skim 1/4" off the lower face, which should make it nearly clear......

I've been trying to work out how to fit some sort of bump stop to the rear suspension, as the ProTech shocks I bought have a fair bit of travel, too much, and the design of the Jag axle means the wheel has twice the travel the shock does. I bought a couple of somewhat spendy cone shaped rubber bump stops from some kit car supplier, but couldn't work out exactly where to mount them.

So, some butchery on the lathe and I turned them into bump stops that fit inside the shockers.

Kinda odd that they never had them fitted as stock.

They're 450lb springs, does anybody know what rate stock Jag springs are, as I feel these may be a bit soft.

Spax were always really helpful with all things shock related.

The jags used bump stop rubbers that bottomed out on the ali hub castings, if the shocks you bought were a replacement for a jag rear end they wouldn't need them.

Jag rear bump stop rubbers . @Morrisman any way of adding them to your chassis/frame?

 

[jsf55]

I did a bit of research into rear springs a while back as the info was lacking elsewhere .... got heated as usual

Jag IRS - Page 2

Does anyone know the spring rate poundage of a standard one for a V12 Jag please. Looking online, I believe they may be around 250-280 for each spring? My mate has had his springs powder coated so there's no identification visible on them. They are far too hard for his car so we need softer...

Best bet is too drive it and try it
I have some spare shock parts and buffers here if you need more

These shocks aren't Jag, they were fitted to the front of some yank tank in a previous life. The Jag bump stops look like they may do the trick, the only place I can really fit them is outboard of the rear 'bed' though.

Interesting thread, strange how defensive/aggressive some folk get on the interweb.

It seems maybe the 450lb springs I have may well be in the ball park for the job. I'll wait until it's fully loaded before I decide whether they need changing up. My axle was narrowed inboard of the spring mounts, so that will have increased the leverage on the shocks.

 

[jsf55]

Mine runs 725lb in total per side ... ... way too much as many have said, but it's all relative too the weight of the car/axle and how much it's ben narrowed

 

[Morrisman]

Another issue raised its ugly head today, training arms for the Jag rear end. Ideally they need to pivot on the same centreline the Jag arms do, now the Jag diff is uncaged and solid mounted.

But, due to planning issues.... there's a pretty convoluted route for a link to get between A and B.

So, the plan is to simply run a rod straight forward and pivot it under the front of the footboard. It's not ideal, but the fore/aft shift of a 3' rod, over 3" of suspension movement, doesn't appear to be more than 1/16".

The flat bar is the planned position of the proposed training arm.



How to join the red dots together with a stiff arm, with cooling pipe, frame and exhaust all fighting to share the same real estate



There is this well used pic of something a Cobra guy built, and he swears there is no bind or tension when moving the suspension through its whole arc.....

 

[mylesdw]

You don't need the radius rods when the diff is solidly mounted.

 

[Morris]

Correct. And if you do still want to fit them use rubber bushes to allow for any potential binding ( as it looks like the cobra builder has done).

 

[Gritineye]

I was just about to say the same, no rubber no rods.
