or vacuum advance and retard elbow.

As Molleur says, it's a plastic tube that varies the ignition timing depending on the vacuum at the inlet manifold.

Throttle(s) closed = big vacuum and little ignition advance so it doesn't stall as it slows to an idle. Throttle(s) open = less vacuum and lots of ignition advance so the spark fully ignites the fuel/air mix before the firing stroke piston has travelled back down the bore at higher revs.

Cheap as anything and available from most motor factors so not worth trying to repair.

molleur, froggyman and Mister Towed - thank you very much for your help. Mister T thank you for the explanation, I understand the system a bit better now. Thanks for the links to order the parts too.

Mister T I hope your Speedster build is going well - did you started the build thread already? I've enjoyed your Sammio thread a lot, so I hope to read about building the Speedster too.

Cheers,D

Any progress mate ? did those brackets turn up ok ?

deni · #85 9th January 2018, 14:54

Hi Gary,

Thanks for asking mate. Yeah, the progress was a bit slow last two-three months. Work is crazy busy lately and some (minor) health issues were in the way too. My build might be a bit slow due to work commitments, but I will not give up building and finishing the car, that is for sure.

I hope to resume the build in a couple of weeks. In the meantime I have been researching and reading about fibreglassing and I have bought quite a lot parts and tools/stuff for the build, so it's all there when I continue, which should be soon hopefully. I have bought some steel box to reinforce the frame, welding mask, main lights and the assembly for them, etc.

Unfortunately I did not receive the brackets, at least the last time I checked, which was just before the Christmas (the car is at different location to where I live and all the car parcels are delivered there). However, I have been told a couple of days ago that I have an envelope waiting for me, so maybe it's your parcel. I will let you know and thanks again for posting it.

Your Formosa long nose bulkheads look fantastic and I really like how the car is turning out so far. It is well built and will be great looking one too, that's for sure.

Cheers,D

THANK YOU ....It was a padded envelope folded in half from memory , so sounds like they have arrived ....

Good luck progressing with the build ...they are worth the blood , sweat and tears ... I did some work on a Miglia recently , made a few changes etc. and corrected a few issues ..it was starting to look very promising when it went back ...

Might be of interest to some one.

That looks good the side profile with the chromework certainly changes the look

Gary-Thank you. Hopefully I won't have to work this weekend and will be able to work on the car. Will let you know if the brackets have arrived.

redratbike-thanks for the tip. Not sure about the chrome, but for the rest it's a very good looking car. I will be happy if I achieve a half of that quality.

Hi Gary, just to confirm, the brackets have arrived, thanks again mate. I have bought steel tubing, so it is really time to start learning welding (which for some reason I keep delaying).

What kind of changes you have made on Miglia you've been working on, what do I look foor please?

I had a few hours working on car on Sunday and will post the photos over the weekend.

Cheers,D.

I fitted a Miglia body to a Spartan chassis and created a tubular inner frame and bulkhead similar to a Formosa one ...corrected the rear arch mis-alignment on the drivers rear they all suffer from , cut a bootlid in to it and created an inner boot , hung the doors , cutting and correcting the fit and gapping as much as possible , made dropped steel floorpans , changed the grille aperture and bonnet area as well as shortening the headrest ......

lancelot link · #92 25th January 2018, 20:12

A lot of work was done to the bonnet and shut area ...narrowed Cobra scoop fitted and bonnet pancaked and hinged from the front ...

deni · #93 28th January 2018, 10:38

Wow, thanks for the photos Gary. This is going to be a very good looking car. I can see that the hump is much smaller than the original, which leaves more space for the boot opening. It's helpful to see how you have mounted your Formosa hinges to the bonnet lid, so I will try to do the same with the hinges you have sent me the first time. Cheers man.

Hi all,

I had a few hours on the car a few days ago, so here are some photos. I didn't do as much as I planned but I am a bit further. I decided to replace the anti-roll bar and drop links, which took a bit longer than expected.

IMAG1618.jpg

I bought a 2nd hand (thicker) one from a Spitfire and bought new clamps, U bolts, nuts, bushes and drop links.

IMAG1625.jpg

The U bolts needed a bit "persuasion" to fit into existing holes on the Herald chassis.

deni · #95 28th January 2018, 11:28

The drop links I bought are the ones from Wolfe Racing. I thing that Mr. Towed also installed these.

IMAG1626.jpg

The were not very difficult to install, even for the novice like me, but I did lost a lot of time trying to adjust the bolts length on each drop link to be as even as possible. I know that the length can never be the same, but the difference in the adjustment seem to be quite big, so if anybody has experience with these, please let me know if this is adjusted ok...

Photo below shows the left one (bottom adjustable bolt) which is screwed in much further than the right one.

IMAG1631.jpg

This photo shows the right drop link. The difference in adjustment, to keep the tension right and the ARB in good position, is quite obvious and it seems to be too big?...so I am not sure if this is installed properly, but both drop link ball joints move freely when the car is on the wheels, as suggested in the installation manual.
I have expected a smaller difference in adjustment though and would feel more comfortable if the right side bolt was also a bit further in...any advice is welcome.

IMAG1632.jpg

For my next job, the dreaded welding, I have bought some 3 mm mild steel square tubing and an adapter for the grinder which will at least enable me to make straight cuts ... :-)

IMAG1617.jpg

Till next time... Cheers,D

lancelot link · #96 28th January 2018, 13:05

The roll of a stock Miglia bonnet can fight against you a bit when you are trying to hinge it ...If you look at the picture a piece of wood has been bonded on the bonnet and under the body to enable the hinges to be mounted parallel to each other and operate in the same plane , rather than against each other ...

You can make this a bit easier by joining the two hinges together , like this but obviously wider apart ...

note also , that the hinge pivot point is back about 50mm from the opening ...this will need a bit of trial and error working out ... but it gives you a starting point ...

Hinges are a right pain to sort out sometimes but look effortless once done ...

Paul L · #97 28th January 2018, 15:37

Deni - I also started learning to weld by practicing some box section.

I found it much easier to weld thicker box section metal compared to the thin metal in the old Spitfire bulkhead I repaired.

Good luck, Paul.

Marc F · #98 29th January 2018, 07:46

I like the angle grinder cut-off attachment - couldn't quite see the make - where did you get it from - it looks just the thing I need.

And good to see progress on your build . Keep it up

Marc

Jaguartvr · #99 30th January 2018, 08:43

I used to have the same attachment. I found it hard to set up and unstable. I ended up throwing it away.
I bought a small metal chop saw on ebay for less than £50. It takes 125mm cutting blades and works very well.

I have a few angle grinders all fitted with different discs because I use them a lot. You can get a quick release nut that you don't need any tools to remove the old discs, well worth investing in.

This one is even better but double the price

Sorry but no link for the chop off saw

Mitchelkitman · #**100** 30th January 2018, 09:09

Is a thicker anti-roll bar the correct move? if the front of the car is lighter than the herald the thicker one could make the handling different ie understeer more
