Roadster Rebuild Diary from Cornwall

Re: Roadster Rebuild Diary from Cornwall

Hi Martin,
On the filler on mine I welded a tube near the neck and ran the breather from the top of the tank to it. My cap is a lockable one and has a pressure relief system where it allows air in to replace fuel used but only allows air (or fuel) out above a certain pressure, I think about 2/3psi. This is a safeguard in the event of it going upside down. Been on the car since I built it, 29yrs , with no problems. As I've got an electric fuel pump I've also fitted an Escort fuel cut off inertia switch so that the pump doesn't keep running in the event of a shunt. Also serves as a theft deterrent as a good tap with a screwdriver activates it.

www.merlinmotorsport.co.uk - I have a 2018 catalogue somewhere, my filing system is just a big black hole!!

Thanks Tony, Merlinsport, Do they have a website? I googled them and all I get is Merlin sports cars.
Anyway a couple of hours after work, 3rd round to me and finished rubbing the tub back to gel coat.

Just got to repair a bit of crazing and plan for the fuel filler. Ideas for the breather most welcome.

Re: Roadster Rebuild Diary from Cornwall

Merlinsport for the tube reducer perhaps. I replaced my filler tube several years ago as it had a slight leak. My tank is an Escort one, the breather was pushed up the side of the n/s spring/damper, not touching of course the moving bits, over the years it has worked well with no fuel fume ingress into the car.
Also, my spare is mounted on an opening boot lid, which is dished and has a reinforcing plate internally mounted, it is abour 6.5" square, cannot get at the actual external mount currently, the security lock on the\stud nut is seized, just given it the plus gas treatment, hopefully tomorrow!

Re: Roadster Rebuild Diary from Cornwall

Next problem to resolve is fuel filler.
The original builder fitted this nice filler cap, it as 120mm diameter with a 51mm outlet.

1st issue, there is nowhere on the rear tub to get a flush mounting for this size, have to look for a smaller fuel cap.
2nd issue, with the new smaller caps similar to this they all have the 51mm outlet but my escort tank has 45mm inlet. Is there an adapter kit available?
3rd issue, where do I route the breather? Looks like the original builder didn’t bother routing one.
Cheers, Martin.

Re: Roadster Rebuild Diary from Cornwall

I solved the water trap problem on my cabrio by drilling a hole at the lowest point in the wheel well and inserting some brake pipe just into the hole with the other end coming out just at the bottom of the tub after a bit of bending to get a snug fit. I then bonded it to the tub using glassfibre mat.

Re: Roadster Rebuild Diary from Cornwall

Round 2 to me. Just another couple of hours to remove the rest.

I have also filled the rear wheel arch mounting holes as the arches looked too high. Also got to lower the running boards (if I use them) as the doors did catch on them when half open.

Re: Roadster Rebuild Diary from Cornwall

This is what I have taken off the car. I think that it is a water trap and only the one hand tightened but to secure the wheel. I could add the 4 studs and do away with the centre bolt then add a drain hole.

Re: Roadster Rebuild Diary from Cornwall

On my Mk1 Roadster the spare wheel was fixed by 2 long bolts fixed to the tub. The advantage with this method of fixing against the solid wheel carrier is it will accomodate different tyre widths. My tub was reinforced by a large piece of 3/4 ply glassfibreed to the inside of the tub. There were wheelnuts which when tightened held the tyre firmly against the tub. The only downside to this was the tyre did leave a mark on the paintwork, still a bit of Tcut soon polished this out. For overkill I did make up a means of locking the spare wheel against theft and covered this with a wheel trim. I will try and draw the set up and put it on here later. David.

Re: Roadster Rebuild Diary from Cornwall

The only difference with mine is that I have a plate the goes inside the boot to spread the load.

Don't know whose pics these are, hope they help
I seem to remember a thread on here about this wheel carrier and I think it had some dimensions - worth a few minutes to look for it !
Or you could make educated guesses from these pics and my tub pic above

Re: Roadster Rebuild Diary from Cornwall

Thanks for the pics. That looks the same as one that sold on eBay a couple of month ago.
I guess the dimensions will depend on the width of tyre. Matching up the studs will be a problems but they don’t have to be Marina, I replaced the rear hub on my daughters Kia last month and knocked the studs out to keep, the good old theory of ‘they may be handy one day’ may have paid off for a change.

Re: Roadster Rebuild Diary from Cornwall

That looks similar to the mount on my berly, if I get time today i'll take the spare off , measure it and take a pic! - it may be later in the week though, a hectic period on other fronts dawns!

Re: Roadster Rebuild Diary from Cornwall

I will take the spare off tomorrow and take some photos.

Hi Adrian, don’t suppose you have a photo do you.
There was a metal one on eBay a while back but I missed the end of the auction, same guy that was selling the other body panels.
May make one myself just need to source some steel, better look in the skip at work again.
