Todays progress was a little slow due to stopping WW3 in the house and then doing homework on Russia :angry:

I looked at the rad crossmember on the car and it's in very good condition, so I decided to just change

the drop mount.

This bit needs cutting out in the middle

f383ae48.jpg

It left some distortion due to the heat put in while welding the modified mount on so the slide hammer was unleashed

Spot welds drilled out of the new rad crossmember

Then added to the old one

No time to weld it on now as the missus is just going to work

Do you keep volcanic laver in your pit, lol.

Yea its like the scene from pulp fiction where you never see in the case but it may hold everybody's soul

Progress

I was feeling a bit flush so treated myself to some Bilt Hamber and some Clecos

200 quid later I wasn't so flush

491bb28c.jpg

The rad support was stripped of primer and prepared for clamping, treated in SAS weld through primer. Was told by the bloke I personally bought it of " It's the best, everyone rates it"

d97891f3.jpg

Welded in and dressed off, for the really Manta anal ( who? me?) out there you will see I've changed the rad support by grinding it into a more aesthetically pleasing shape :ph34r:

So the next job will be spot welding on the rear quarter

I don't use the spot welder that often so I needed to find the parameters of the weld and test the integrity of them .

I also am using an unknown weld through primer....

Test 1.... spot welder and a piece of Manta panel

665a8fc3.jpg

Cut Manta panel and treated with SAS weld through primer

168ebfcb.jpg

I clamped the SAS primered panels together and put the spot welder on max.

Not a single brrrrrrrssssstttttppppp from the welder! Weird?

Again and again I tried, nothing.

d0bb0e0a.jpg

The small test panel in the same picture above was squeezed with the same spot welder on the same power and it stuck hard.

The weld through primer doesn't seem to be a weld through primer..........

So I stripped it off and reprimed with the Bilt Hamber electrox..

Bssssssppppppttttttttttt, it went through the Bilt Hamber stuff :)

7c63c9e9.jpg

I tested the weld strength and it was stuck so hard I had to crack out the spot weld dril

Next thing is to find out why my compressor isn't working and it's in a real tight space!!

Not done any Manta work as the compressor was broken so I decided to take a good look at it and remove the heads to see if anything was broken

a47c5699.jpg

What I found was that one of the valves was split and part of it was missing

e2a7cf94.jpg

The spring was also NS so I nipped to work and got my orthodontic pliers and wire and made a new spring

4b24fb2b.jpg

I made a new valve from 1mm stainless and set it an after giving the heads a full strip down and inspection clean

ff391cc8.jpg

New headgaskets made from gasket paper and built up

Up and running and a full power:clapping:

It just shows how quality engineering doesn't have to be thrown away and can be fixed :hug:

Yesterday I was cutting up a hatch that had most of it's useful parts removed by Rutts ( so don't blame me :rolleyes: )

I gassed out the tunnel

494afb6f.jpg

And I also need to replace the 'ears ' for the radiator as I have a radtech racing one

82345b63.jpg

Replacing this and making them look factory again is going to be loads of fun :blink:

2d34b854.jpg

874d9b69.jpg

Horrible sierra tunnel top cut off ( I should of been shot doing THAT to this shell :o

Used a new panel removing chisel on the air hammer, worked a treat!

1abdfe4e.jpg

You can now see the remains and notice I've stupidly cut through the seat belt mounts and the Manta handbrake hole/ bulge too

ea45f8d8.jpg

Also because I like to do loads of jobs at once, I started to strip the roof rails for the roof inner

Well, I've managed to put about 20 hours into the car over the past couple of weeks, time just gets burned soooo fast in the garage

First I fitted the EPS mounts supplied my manta sport, great fit and highly recommended

62EBEE3B-0D2B-4D79-83FC-51A3A71BA962-7100-00000A3B7412C0BB.jpg

Trimmed a spare dash to trial fit

A367F8B7-A550-4E8C-A11C-A697023A5F1E-7100-000008D6C4BF455C-1.jpg

The whole thing fits like it was made for the Manta originally

9E497493-6546-4314-9D2E-0126ED8EF4B0-7100-000008D3C73ACB87.jpg

Next job

I trimmed the last of the horrible sierra tunnel off and started to strip down the replacement Manta tunnel.

It took hours and hours and hours, hundreds of spot welds to remove <_< hmmmm spot weld drills are rubbish and expensive so I made my own following the tutorial on retro rides from tonybmw ( check out the thread it's fantastic!)

It works better than my Presto ones!

ABDC2621-2792-49E0-8C2F-3B23306361CE-8607-00000B61D1489710.jpg

Seat mount removed for access to spot welds holding handbrake mount

A6806320-CBA6-47CC-BF86-35E4F0473FE7-8607-00000B5E51FC19AF.jpg

Old handbrake remains removed with spot weld drill and chisel and replacement one removed using spot weld drill ( see where this is going!)

73BA5406-5074-4AF0-A8BC-C85A3CE5A664-8607-00000B5E919FA8B5.jpg

Old seat belt mount I'd cut through for the sierra handbrake mech so I removed the old remains using the spot weld drill and removed the replacement from the replacement tunnel using? Yep, the spot weld drill

Pic of replacement inside tunnel

Trail fit of the replacement tunnel, still need a bit of adjustment but getting their.

9C44D052-0C15-4CAB-B29D-E6121BE0A6D1-8607-00000B5F28C7D7E2.jpg

Then I decided the replacement parts need blasting before I put them back on but my blaster is in a right PITA place and need lifting up and down every time I need it, so I decided to play with my new toy..

Plasma cutter :D

Made some plates for the bottom of the legs

2B6B0F90-6B5F-4284-8B46-90962B3C77B3-8607-00000B4D4E8EF1F3.jpg

Cut some legs and welded them on but I didn't realise until I'd stared welding that the plates were galvanised steel! What a pain to weld with goggles, and a mask on!

D3CA5E39-5B95-4697-8BDC-8F094467A902-8607-00000B525DF22E4A.jpg

B2130932-1291-4B1E-9E23-678CCCE3681A-8607-00000B547246F0DB.jpg

Added some industrial bin castors ( thank you baycrazy for the 99p rollers!!)

AC343BC3-B35D-44F6-BA3A-71916C08316D-8607-00000B5BBE5D1227.jpg

Only thing to do now is to add some cross bracing that will give me a shelf but it's so much better now as it's at the correct height and easy to use..

Time to put the glass bead in?

ARRRRGHHHHH where's the bung gone from the bottom!!

B66E63B0-EF52-4307-8A7C-35DDD2795947-8607-00000B5F7831D121.jpg

Ah well there's always tomorrow :rolleyes:

Blaster now on proper legs and base :) It's the little things that keep moving on

96D618E6-5B1C-4B80-9431-ACFD1EF64485-3307-000002C98048FC6E.jpg

Torque tube off so I can position and grind tunnel top

Hoist into position on gantry

A125C5A7-6E35-4C8B-AA01-1507A89CA07C-3307-000002B47F2FF5C6.jpg

Engine up

228901BF-78FC-480C-B657-FB2A037ABB37-3307-000002B46A6CDE82.jpg

And in

A9EAAD71-D7FF-4AAC-B1E6-303432ED566B-3307-000002B45F2CAE76.jpg

Really tight at the back

4E3BB277-154C-4803-9B7F-125F3E2A8E40-3307-000002B44A14EDA0.jpg

This was to see how the new T5 bellhousing and getrag 265 box fits

Hmmmm :( this in in neutral

94B46A3A-6EAE-44F4-9F9F-487639A9AEB7-3307-000002B431917FEB.jpg

Arrrghhhh... I will now have to do a few things

Engine will come forward an inch, that's not bad as I have this much clearance

F5F88330-F52D-475C-9BCB-067EE3A20589-3307-000002CA2D78B41A.jpg

I will move the holes in the mounts forward by an inch or so

85B56DFB-09A5-4251-9F42-33C0CA271548-3307-000002CA555155D4.jpg

82D1B9FF-2C4E-4530-B275-C0F10A12D83D-3307-000002B458A61206.jpg

This will lead to some fun with the crossmember :angry: It's tight as here

B14963C9-9637-4313-A03A-469BCD1AE232-3307-000002C9DB1669E1.jpg

5FD8E9CB-22E3-4DAA-8363-C82D6CB88501-3307-000002C9B0C96838.jpg

The lever then will come into the centre of the hole by an inch, but I need two or more to centre it

02DC60F5-082C-43A2-A744-0449F273BA20-3307-000002CAA8314C1E.jpg

I'll take an inch out of the remote and move it all forward by an inch

E9C99B35-331C-471A-AD30-61D79A25B50B-3307-000002CB37196A9B.jpg

I'm going to have to make some adjustments to the gear lever remote

holy shit that's gonna be an interesting few tweaks to get that in there, seems that every adjust causes issues elsewhere, very challenging puzzle and not the easy cook book solution.

I think its going to be incredible if it works out and I am pretty sure others will learn a lot from this thread, your leading the way on this one I think.

I love the gantry crane - handy

tight squeeze in the garage tho mate, don't envy you there

mate of mine here did a cossie turbo conversion in a Mk1 Escort rally car for a guy that had plenty of money, he kept telling the guy to dry sump it (not sure what the reasons were) but he didn't and it all ended in tears, the other thing that sticks in my mind is him saying its an awesome package when its dry sumped. I don't know too much about it but I would say its probably well worth looking into

That's the problem I kept having with the engines in my Chevette! Ibthink the easiest way will be to modify the sump. Might nit be the cheapest, but would be better/safer than cutting and modifying the crossmember i think.

It's a good project, and was good to see it in the flesh, lots of work gone into it.

and Re. Chevette, have a look in this project diary on our website, a turbo XE with standard manta sump and Omega gearbox fits a chevette very nicely

http://www.retropower.co.uk/projects_LET_Chevette.php

I did find out about the big wing sump and XE/LET engine. I put up a post on here looking for a big wing sump, and that led to me buying a full rwd setup off Kev! His 20LET, and everything I needed! Had the engine in within 2 days!

I have been looking through your website and build logs to see what you have done, and how, has been very helpful :-)
