Chris's new build of an MX5 based car

[CTWV50]

Found this, It's a discussion about exactly this with some seemingly knowledgable people trying to get to the bottom of the Staniforth correction factor for angle. I'm not sure I'm able to apply it but I'll give it a go.

There is this as well, but to me this is as clear as mud. I assume this is from Staniforth's book.

An observation and hope I am wrong,I don't think the IVA tester will like the fact that the locking nut for top suspension joint holds the flexy pipe bracket as well.

Yes I have questioned that myself, I may get hold of a 2nd pair of drag link lock nuts or maybe weld the bracket to the upper wishbone. Thanks for the observation.

Last night I made some spacers for the rack just to make sure mr IVA man didn't fail me due to the rack boots touching the wishbones. I'll probably remove them after the IVA as the contact is only very slight. I'm using 12.9 strength M8 hex head bolts with washers and flanged nylock nuts.

I've decided to give making my own fuel tank a go. The one I was using had a few small leaks but the main issue was keeping the steel flanges from the mazda tank attached to the ali tank. In an effort to resolve this I decided I'd make a steel tank. I wanted to originally but never thought I'd be able to. So never one to shy away from a challenge I made some tank end plates and a sump and tested them with fuel and they didn't leak! I took the end plates to a local fabing place and had them bend some sheet steel to fit by end plates.



They did a good job and it was something I'd never be able to get even close with but there were a few gaps to deal with.



It was made in two sections as it wasn't possible even for them to bend it in one piece, but it made it really accessible to install the baffle and sump in the right place.

It's still not finished as I did have a few small leaks but it's getting there. To be honest I'm surprised it's gone as well as it has.

[CTWV50]

I was getting a lot of leaks around the pump/sender flange. Fuel was creeping around and under the old flange behind my welding (I think). I've now managed to come up with a technique to fill this gap with plumbers solder.



Needs finishing off.

Hi there. What thickness of aluminium did you use for your spacers

I've just realised I've got a problem there as well! My car now looks like it has been taken to bits. I most likely going to have to move my radiator upwards.

THIS IS THE BAR I USED BUT YOU COULD PROBABLY GET AWAY (oops caps) with less thickness than 15mm. Why will you need to move your rad?

30mm x 15mm x 250mm

I've mounted my radiator fairly low and the bottom hose will now rub on the steering rack.

All part of the fun of building a car. I kind of hoped my car was nearly finished but now it's in lots bits in the garage.

Thanks for the link
