Does anyone know if all the tubes are internally connected ie would that hole drilled in the pic allow fluid access to the rectangular bottom rail, and onwards to the rest of the chassis and outriggers? Your post suggests it is all linked? I have a perfect chassis on my new Griff and I'd like to fill it with gloop/oil/anti-rust-yoghurt or similar. Sticking one side of the car in the air and pumping gloop in at the high side through similar 5mm holes may well work?
Andy, some of the tubes are interconnected, some aren't. I know because I put an airline on them to see. Each long rectangular chassis rail is interconnected (but not connected right side to left side) and you don't have to drill it to fill it with gloop as you could do that through the front and rear body bolt holes (two in the boot and two below the radiator - there may be more) Each sided outriggers tubes are interconnected but not connected right side to left side. The rest are generally not interconnected and had to be drilled individually. I hope this helps. Pete

Hi, thankyou for that - yes it definitely does help - although my body bolts ain't coming off for a long while yet I hope.
Sounds like two holes per outrigger top tube near the top main rails and a couple in each main chassis rail might access the majority of tubing.
I remember hearing of chassis being cut open and rusty Blackpool rainwater pouring out, don't know if that was because corrosion was letting road spray in though smile

Quinny, I've been searching for hours for that photo of your car - I couldn't find the thread but I remembered it from a couple of years back. I was planning to plagiarise your clutch master cylinder cover. You don't happen to have a mould or a spare I could take a mould from do you?

Other thread is this one:

It's Marty V8's car
Sorry mate....no. No mould and no spare.....maybe Steve can helpsmile

Re the fibreglass cover - I know a good fibreglasser - he did my pond. He's also worked for TVR/Al Melling previously so does have TVR experience smile
I could ask him for a price providing he could get a suitable cover to borrow - there'd be a cost for the mould-making then a unit cost after that.

Guys, I have all the gear, the gel coat for moulds the GRP mat, the resin, wax, release agent etc. but what I didn't have is a cover for the clutch master cylinder nor a way around making one. I had some ideas but the best option would be to take a mould off Quinny's if he is willing. My intention would be to produce moulds for all the hatches/covers and make them available to the Griff/Chimp fraternity. Haven't worked out how that would work yet as I hadn't planned to go into major scale production but I would like to share everything that I get out of this - anything to keep these cars on the road - I also need to finalise how I'm going to fix the hatches.

Quinny, I could PM you my address with a promise not to break it. I am back to Kazakhstan next week for 5 weeks but then could take a mould off your cover as soon as I get back, say 2nd week in December and then get it straight back to you - if I fcensoredk it up (which I don't intend to), then I promise to replace it.

PeteGriff seems to be a bit of a mentor on the production side. Pete, got any better ideas?

Quinny, I've PMed you with my contact details. Don't worry about the brake master cylinder cover as I have one already and I don't want to risk yours. I will undertake to make mould/covers available to all although it won't be until the new year some time. I will need to experiment with fixings unless everybody wants to play with their own....!

By the way the LS3 motor has not gone unnoticed. No wonder you SORN the car - a bit hairy in the snow and ice....? Pete

I'm only SORN ing it cos I've got a couple of jobs I want to sort and the tax is due at the same time as one of my other cars...

This way I won't need to rush, and it'll seperate the tax burdensmile

For those who remember or care, it's been a long time coming but I'm back on it. A bit of early retirement and having finished many of the pressing projects around the house I can finally put my mind back on the rebuild.

I thought I would ease myself in gently and rebuild the callipers.



Stripped them down



and got degreasing





I'm not sure about the ultra-sonic cleaner. I think it does a good job and the good thing is it heats the solvent which adds to the effectiveness of the cleaning, however I reckon I could do the same job in the parts washer with a good scrub.

I gave the callipers a good blast



and then powder coated them




and into the oven. I reckon my powder coating skills have improved and I realise that you can really load the powder onto the callipers and on the rough finish of the callipers it really helps to smooth out the casting. You will note that I used a combination of silicone plugs as well as old bolts and pistons to keep the blast media and powder coat out of the internals. I like the silicone plugs but they do get blasted out by the airline as well as the heat from the oven expanding the air inside






and on to the rebuild. I did a bit of shopping around for the rebuild kits including new pistons and ended up with Bigg Red. Spoke to a bloke called James Priest who couldn't have been more helpful and the prices were very competitive. He also threw in clips and springs for the rear callipers as well as titanium bleed nipples because they didn't have any stainless steel - couldn't be fairer than that....

Front callipers are pretty straight forward



There are a number of ways of getting those dust seals on. I put them at the bottom of the piston and used a plastic trim tool to ease them into the seating, it worked for me





The rear callipers are a more difficult and the first one I used the press to compress the spring to get the circlip in



However the next one I used a G clamp and socket, more controllable. Don't have a photo but this is the little tinker when stripping down





Handbrake mechanism





A couple of tips here. I do have a bore hone, however the bores where in good nick so I generally used a die grinder with a range of little wire brushes



essential tool for the rear callipers was this long nosed, right angle snap ring pliers.




These are Laser from Amazon but I'll bet there are plenty of options there and the other essential ingredient is rubber grease



Note I am using old bolts for now but will replace them all when I start putting the car together. I will also have a go at re-plating some of the components. I've got the kit, I just need to start using it.

For those that are interested I'll follow this up with the next episode of the rebuild. I need to put my mind to sorting that chassis out in the new year......

As you can see I want to do as much of this work as I possible can so next jobs will include the diff, the gearbox and of course the engine itself. I am also interested in putting in Impreza power steering but that is also for next year.

If anybody wants to give it a go themselves then happy to help where I can.

Have a good Christmas and New Year chaps.

Pete

Most certainly interested Pete... and surprising what one can learn from such accounts as yours. Plus, you must be experiencing a lot of satisfaction by approaching your project methodically with such good attention to detail whilst pacing yourself. As they say: all power to your elbow!

Especially important as the whole job 'has to be fun!' - just as the late Gerry Marshall said about his racing in general, the TVR sort in particular!
