Edited for future users asking the same question:
5mm plate is best, 3mm will probably distort when welded.

Original post:

eyup,

got my gsxr750 carbs for a 1.8 cvh, and I've also got a dwg/dxf file for an inlet manifold plate to be cut, so I just wanted to check what thickness should be used. I thought 3mm would be about right or should I go for 5mm to ensure there's no chance of warping?

Also, could anyone recommend a firm who could do it for me (ideally somewhere in north or west yorkshire where I could email the file and then collect). A guy at newark show said he'd charge about £30 + postage for it doing... Is this a decent price?

Sounds pretty good to me!

I've used http://www.laser-eng.com/ in the past and they're up that neck of the woods. I just e-mailed them the drawing each time and they sent me the bits.

IIRC they have a minimum job price of 35 quid but you might get two for that

cheers mate, just emailing them now. Reckon 3mm would be adequate enough?

I would do it out of 5mm, to minimise distortion.

Have a word with 3GE components on here, they may already have a template too. Their prices are excellent too.

3mm is too thin IMO, welding the flange will warp it.

cheers guys, I did wonder will give 3ge a shout

Make it yourself, I have a bit of 5mm you can have, use a gasket as a template, daisy chain drill the holes and file round job done.

Cheers

5-6mm is the way to go

Would need to be 5mm + to stop it warping and so you can get a good weld onto it.

Possibly you could cut that with a Jigsaw and a lof of paitence I managed 8mm Ali with a jigsaw and a large can of oil.

yes, i used 5mm steel plate, a cut it from a old gasket, i drilled the hole buy hole saw, and laod of cutting oil, it took some time but it got there.lol

Shorttrack does his in 6mm.

Another vote for shorttrack here.

Excellent work and a fair price.

5mm Steel, use a gasket to get the position of the inlet holes and the bolt holes, chain drill the inlet holes and file to size.

This is LocostBuilders you know

But £20 to get it done all nice & posh isn't on a par with a thousand pound engine management system :p

Hello Paul

I can laser cut 1 for you cost would be £18.50 +P&P in 6mm Mild Steel

If its any good to you U2U me and i can let you have my Email to send a DXF file to.

Look forward to hearing for you.

Hi Paul. Think these are near to you.
KJB Eng at West Tanfield Ripon.
kjb.eng@virgin.net

I have contacted Joe Knowlson who works there.
They are good and don't mind doing one offs.
They do alloy 1mm to 3mm and most size mild and stainless.
8mm mild steel is best to resist warping, but you are still best off bolting it down to a thicker block or some angle bar when welding it up. I found the pinto turbo manifolds i did could still warp when bolted to an old head if they were not left to cool down fully.
