Been making manifolds again!
NS Dev - 29/4/10 at 10:19 AM

Not for a locost, but an XE that I'm putting in a Kadett C Coupe that we've been rebuilding for a customer, thought you might like the shiny bits!!


























NS Dev - 29/4/10 at 10:20 AM

PS, obviously if you want one for a locost, I can oblige!


liam.mccaffrey - 29/4/10 at 10:21 AM

Love it

the collectors are


prawnabie - 29/4/10 at 10:22 AM

making something like that is all well and dandy, but making something like that that fit inch perfect is TOP WORK!!!


blakep82 - 29/4/10 at 10:22 AM

oooh


mangogrooveworkshop - 29/4/10 at 10:23 AM

That is very nice work.....


mookaloid - 29/4/10 at 10:28 AM

That's art


cd.thomson - 29/4/10 at 10:29 AM

im proud of my exhaust, but that is a very fine piece of work


boggle - 29/4/10 at 10:32 AM

do you pickle all the welds up after???

i personally hate to see loads of joins in an exhaust system, also i was allways lead to beleive that the more joins you have the more exhaust turbulance is created causing a hinderence in power gains???

however its a lovely job there...nice one..


Red16 - 29/4/10 at 10:36 AM

Very nicely done

Do you purge the inside while welding to get the bore clean/smooth like that?


rost - 29/4/10 at 10:44 AM

NICE!


jabbahutt - 29/4/10 at 10:45 AM

I don't know how much these things cost but maybe you could talk to this author of this thread as he's after a manifold

Yea, would be lovely to have a mandrel bender and eliminate a few welds, but I don't have £10k burning a hole in my pocket at the moment!

As for power, well with 2" primaries it won't be a problem! If anything they are a touch big for the lower end of the power range (say 200hp) they are more suited to 250hp range.

Main thing is the proper tubular collectors, the horrid sheet metal pressed ones cost lots of power where the pipes go in and out.

I can pickle the welds, though to be honest they just polish up without the pickle and I hate using the bloody stuff (hydrofluoric acid is pretty unpleasant!)

I will see what the customer wants on this one.

If my main line of work was manifolds I'd put a bit more effort in, but this is just filling a gap where nobody makes one for the job.

NSDev, if you could put more effort in then id hate to see something you'd put your mind to. I probably die of envy lol.

Also - finally a supplier who is candid about prices... it does my head in when people shirt around how much they paid/charged for stuff.

I keep eyeing up your mini van on ebay if I'm honest. If it wasnt such a horrific colour then id be serious tempted


blakep82 - 29/4/10 at 11:00 AM

what mini is that? ^

you are looking in the wrong place!!!

mine cost 1500......inc shipping...


NS Dev - 29/4/10 at 11:39 AM

£1500 for a mandrel bender...............I think not! Either that or the price was with no tooling, just one mandrel is more than that!!

I have a pro-tool bender and range of die sets for doing roll cages, and it will do limited bends on exhaust stuff, but no good for tight bends off the head etc.


boggle - 29/4/10 at 11:44 AM

bender

That's like the pro-tools bender.

I think this is the type of machine NS Dev is talking about.

boggle - 29/4/10 at 12:06 PM

but my point being that you can bend tube for under 1500 is viable!!!!

if you want to go mass production then fair doos....


NS Dev - 29/4/10 at 01:27 PM

LOL I have a pro-tools bender but it wont bend the tube in the manifold that I started this thread about!!

I can do a bit and show you the result if you want!! It wrinkles it on the inside radius, and that is on a 7" rad die which is not tight enough for the header pipes!

Anyhow, I can relax now, for a moment I thought I had missed out on a mandrel bender with tooling for £1500!

Aye you got it! Would love one, something for the future! The pro-tools one is superb I hasten to add, just not the machine for this job!


boggle - 29/4/10 at 01:44 PM

there was a chap i new who made a bender on some weird trolley setup that never crinkled the the tube as it pulled it through...im sure it was on youtube???

PS Think the best summary of the colour that I've heard was "cowshit green"!!!

We love it though, its as retro as an avocado bathroom suite on wheels

On ebay auction from this eve, fed up with messers!!


scootz - 29/4/10 at 04:26 PM

Lovely bit of work!

Can anyone expand on 'pickling' for me please... I've never heard of that before!


NS Dev - 29/4/10 at 07:02 PM

When you weld stainless it, amusingly, stains!

You use a commercially available paste made of hydrofluoric acid to remove the staining and oxides.

However, if you look up hydrofluoric acid on wikipedia etc you'll see why I avoid it when I can!

That said I have done a stainless engine cover for the v8 van we're building where I have to pickle the inside welds as I can't get in to polish them properly


scootz - 29/4/10 at 07:08 PM

Cheers!

Very nice indeed good skills.
