pretty sure its this http://www.ebay.co.uk/itm/3M-Car-Body-Schutz-Black-Underseal-08861-x-12-/110647444902?pt=UK_Body_Shop_Supplies_Paint&hash=item19c31a05a6 which is what I think you have seen, I will double check the part number tomorrow (if I remember  ) its only available in black, what do you want to do in clear?? j

Chugga - just a reminder to look for the part number...., and Clear for inside door skins - or is there a better product the also acts as a sound deadening as well as waxing?

That is a great device. I have one but not is such pristine condition. That is a cheap price too.

These are the two products recommended by James which we used on the Fanalone using a 3M gun which was way more expensive than the Ebay one above.

Excellent products and super results but do make sure you wear a good quality mask (not the paper ones) as they are very toxic.

there we go Tim Robin has confirmed the underseal/ shutz , wurth do a fantastic cavity wax in shutz cans I will get the part number............when I remember!! the 1st sealant that Robin has put the link to is a rubberised sealer that can be over painted and ideal for under wheel arches etc but very expensive , again top quality product

There is still a delay on the grease cups for the sliding pillar thrust bearings, these will now be out sourced. I will take the opportunity to get 2 new hinge pins made as, during the dismantling process, one had to be drilled out and another was found to be a bodged replacement.

So ...... what to do ..... As I stated in an earlier post it should soon be time to drop the shell off the rotisserie and onto its axles. A delay on the front axle means time to turn to the back axle. Today was the first time in 14 months that I managed to get in a full day on the car and I tried to make the most of it. So, the rear springs which had previously been rebuilt with new interleaving and silentbloc bushes were dusted off and, fitted with new bushes to the front mounting, the lefthand spring was fitted. The photograph shows the state of the front mounting bushes as removed, one is missing having disintegrated, two were simply thick wall rubber tube, split to aid fitting and the only one that appeared to be original is, shall we say, obviously past its best!!

The other job for today was to fit the adjuster snail cams to the brake back plates, every little bit helps, even when it's a little out of sync !!!!! I  will not rebuild the brakes at this stage, I just want to get enough done to get the wheels on and the shell mobile.

I hope the photographs are attached!!!

Great work Andy!

What is the latest on the Appia?

Tim

[the.cern]

The Appia is still laid up in the garage!! The gearbox is out and has been checked by an independent specialist who has reported 'no fault found that would/could give rise to the knocking noise'. The problem has been finding the time to get into the garage and refit it. I have a new clutch plate, so it really is just a matter of making that time!!! Jim has said he will help, but it is a two man job and as I said in the post above, today is the first time for 14 months that I have managed to get a full day. However, as things get easier I hope to make a day to get the gearbox back in. However, although that is a desperately needed action, unless there is a miracle, the original problem will still be present and will remain to identify and overcome!!!

Time will tell .......

Every little counts Andy, bet it felt good to get the old mits dirty again!

So when gearbox back in, will you drive car again, have you tried using a multi channel electronic ear/stethoscope to localise noise?

I can only assume they work and will be of some use?

You'll be taking her for drive soon .... looks great. Compared to a Fulvia, for example, the spring hanger bushes are quite light.

Bit of deja-vu seeing the backplates and adjusters. Very similar to the Aprilia system of course. Did you manage to tap the locking pins out or was it necessary to drill them ?

Hope you are able to get another day in soon !

[the.cern]

Frank, I will most definitely be driving the Appia as frequently as possible, once this damned knocking noise is sorted. It was bought specifically to be a, within reason, a daily use car and I am not minded to change that. I think I may need such a stethoscope, but the noise had become so bad and easy to provoke that, once she is running again, the first thing I will try will be to put her on the ramp at my local friendly MOT place, jack up the rear axle and drive it against the handbrake to see if we can get the noise whilst checking from underneath!!! I just hope this will happen sooner rather than later!!!!

Simon, I had noted from your postings the similarity between Aprilia and Aurelia brake parts. The one thing that has surprised me about the Aurelia brakes is that the Aurelia front brakes have a leading and a trailing shoe, whilst the diminutive Appia, has twin leading shoes. Anyway, in due course I will discover how well they function, they were ok when I last drove it ................. about 35 years ago!!!!!

As to the locking pins in the adjusters, we managed to drive out 1 of the 4 on the fronts and 2 of the 4 on the backs. All the others were drilled out. Jim will make 8 new pins (or I might cheat and use roll pins!!!!)  The other part to be made for the adjusters is 1 new nut, 1 split whilst removing the locking pin!!

I can manage a part-time day today, but things will then go quiet for a couple of weeks as I have to 'do' the gift trade Spring Fair at the NEC starting a week today.

But it is great to be back in the workshop, I didn't even mind rolling around on the floor under the shell, fortunately for only 10mins!!!!

The thing is Andy, the noises can only be reproduced whilst on the move, at certain power/load/revs....perfect circumstances in which to use the stethoscope.

I had the pleasure of riding with Andy with my head in the footwell and hand against the bulk head. I was convinced that the noise (and hitting feeling came from the bell housing area. If the gearbox has a clean bill of health (and I expect should otherwise the noise would have very quickly led to a bigger noise...) then flywheel/clutch/release mechanism has to be carefully examined.

Andy
I have some capacity this week or after 24th Feb if you want a pair of hands to put the gearbox back. Give me a call!

Tim

[Parisien]

So as gearbox already out, a further strip down required, hoping its resolved soon, as I'm sure Andy's had his fill of the current situation!

[the.cern]

Tim, a very kind offer, I will see what the next few weeks throws at me!! Hopefully Lynn will get an all clear on 12th Feb and then its a matter of trying to regain her strength before her next trial in the late summer. So, all being well I should be able to get a little more playtime in the spring.

Anyway, today saw another visit to the workshop ................. and then there were two, installed rear springs that is !!!!!!
The 3 photographs show both the springs in place, the rear mounting and the front mounting. We discovered we had no split pins, hence the bits of wire, purely temporary I can assure you. The  4 'stirrups' over the rubber 'cotton-reel' bushes of the front mounts seem of quite light construction being simply formed flat steel bar. These are secured by 2 bolts each, 8mm dia, 1.0mm pitch, which we had mislaid so Jim made new ones whilst I made 8 tab washers to secure them. The tab washers are not standard, but I feel uncomfortable about the bolts not being secured/locked in any way !! 

We are hoping the sliding pillar thrust bearing grease cups will be ready within 2 weeks whereupon we will be able to complete rebuilding the front axle. Then it will be time to install both axles, attach the brake back plates and drums before adding the wheels and dropping the shell off the rotisserie. That will be a momentous day!!!!!!

Let's see what happens .....
