MX5 based build thread

welcome Chris....nice to see another build being born, if you get stuck you will always be able to find an answer within these "walls". I would advise getting a larger capacity gas bottle as you will find those you are using don't last 5 minutes ( that is almost literally ) try and get a pub bottle if you can.

Thanks, the gas bottle was an emergency spare as my usual supply ran out when I was finishing my mini project, I just haven't got a refill yet.

Evening all!

I managed a good few hours on the build tonight with some good progress (well I think so)

So I left yesterday with the base rails tacked down and the front frame aligned and tacked, today I moved on the seat rails, uprights and some top rails.

I started by tacking in the two rear seat rails SB1 and then U4 and U5.




I then got d8 roughly in place and then TR4 and D10.

All clamped in place and measurements checked


I checked, checked and checked the measurements and then tacked them in, I forgot to mention I put SB2 in place also.

What I did find is that when placing D8 onto SB1/SB2, they didn't seem to fit fantastically, I can see why, so I fiddled around until I was happy enough with the portions and then tacked them in place.

First attempt with SB2 not sitting very well


Second attempt, better, not fantastic but I was fairly happy with this and I tacked it in place, the gap at the top of D8 to SB2 looks bigger in the picture than it is.


I then moved over to the passenger side and did the same and then moved onto U6,8 where I had some issues placing them, I'm still not 100% on these and there just resting in place until I figure it out tomorrow. I did fit TR1 and TR2 and got them tacked onto the front frame.

[CJ27]

I left it tonight pretty much at this stage and tomorrow I'll move onto finalising U6 and U3, U8, U7 and getting TR8 in place.

If anyone could shed any light on my question in the chassis section it would be appreciated.

A small note on my measurements, I've been checking before every tack my alignment of each tube and the overall chassis to check for distortion etc, I'm happy to report I'm + or - 1mm overall on all my sizes, I'll check every thing again before I fully weld.


A final picture before I turned the workshop light out



Night all.

You're supposed to chamfer the bottom edge of the diagonal tubes D7, D8 where they interferes with the seat back rails, see their drawing on page 165.

Ah, I missed that bit, thank you, that makes sense now, I'll sort that later.
