Thanks chaps, that gives me something to work from, I have a fairly good (actually called) body shop supplies shop here, so I shall stop by after work on Monday and see what they have to offer. Today I have been mostly scraping off seam sealer mostly that is except for an extra long BBQ lunch with Mrs and mrbadger no pics of that, but I did take some of the bulkhead.  Which of course revealed more holes.   And a quick wash down with stale petrol got the last of it off.    Tomorrow I shall dig out the spot blast gun and fire up the compressor and hopefully clean up the last few bits. Dan |

What kind of breathing apparatus do you need with that Mark?

Oh, wasn't that fun, the spot blast gun didn't, so I had to break out the normal blasting gun made a huge mess, used 10 litres of already spent aluminium oxide media, got covered in it, didn't even get all the paint off, and completely forgot to take a pic Then I attacked the windscreen pillars which now look like this  But I think ill start fixing that tomorrow after work.  |

Went shopping at body shop supplies yesterday and bought: 1l of 2 part epoxy primer 5l thinners 5l panel wipe Big stack of mixing pots Some filter cones Some gun filters A tin of weld through primer £61 which seemed a sensible price I checked and the epoxy primer is non isosonate-wosit-nonsence so i don't need a full breathing equipment, my normal 3m respirator will be fine. Today I got a couple of hours in the workshop after work as a meeting was cancelled. I cut out the return of the windscreen pillar, despite the centre point from the spot weld cutter breking off, a crafty cutdown drill bit replaced it and got it working again.  I didn't think it looked too bad, cleaned up taped off the weld areas and gave it 2 coats of hydrate80 before it was time to go back in to cook dinner.  Hopefully they won't rearrange the meeting after work tomorrow and i can crack on. |

No meeting after work so it was straight into the workshop I weld through primerd the inside of the windscreen pillar  Then followed the usual recipe of CAD template  And Transfer to steel  I had originally planned to put a return on the long edge going to the front of the pillar but there's a gentle curve aand the shrinker strecher ive borrowed wasn't deep enough so i hope my welding skills are up to the task, the good news is its hidden in the back of the gutter so it doesn't have to be perfect. This is the paint i bought  I'm thinking about bonding the gutter plate on to stop the rusty nightmare getting started. Dan |

I have in my possession a 3.63:1 ratio spitfire 1500 diff, it's not quite as good as the 3.27, but that one was only made for Swiss 1500s and non OD GT6s which would have been my first choice but, they command a high price and 3.63 is far better than the 4.11:1 that's in the car now. , According to the gear calculator using standard spit rims with the tallest tyre I can find for sensible money a 175\80\13 uniroyal at £52 a corner 70 is at just over 3500 rpm, but if I switch to an mgf \tf rim I can get a 195\65\15 no name tyre for £32 or a uniroyal for £43 a corner. Which drops the 70mph revs by 200 rpms So I'm on the look-out for some mgf\tf 15" rims if anyone has some gathering dust in a corner let me know. Dan |

What are doing with the rear suspension? I was thinking of going to 14" in the hope of getting tyres with a higher speed rating, but it's not worth it. 15" would allow me to get tyres with a rating above 120mph, but I want to keep the original suspension and rubber band sidewalls aren't going to be a good idea.

Hi ferny long time no see fella I'm looking at 195/65/15s which are slightly larger rolling radus than the stock and 65 should be a reasonable side wall to allow for the suspension swing, i have a couple of options ether (what i belive to be) a van spring or change to a spit swing spring. Possibly with some monroe air assisted shocks. Dan |

Today I'm not sure what to do, but I should start yesterday, I had a closer look at the its been siting around under my bench see if its any good, spit diff. First thing is the nose bracket has been removed, and the pinion nut hasn't been put back in the same place and there's a good few mm of in out play on the input shaft. I spent some time scraping a reasonable layer of oil infused muddy carp off the outside of the casing. The contents of the diff are very dark grey thick oil. Someone's obviously been here before because all the output shaft flange bolts came out with barely a murmur of protest yep the worst one took a light tap on the end of the Allen key to free it. As it's the first time I've been in the workshop for a while iam so completely absorbed I forget to take any pics. I clean everything up with some stale petrol and look at the gears which look like this.     Then I dunked everything in the sonic bath and retired to read the workshop manual, and for the first time in a long time I felt completely lost, the up shot is the sun gears inside the cage seem to need shims, one side has approx 1mm and the other 2-3mm of play, the output shafts have some movement in the splines. Is the play in the splines normal? Are the main gears worth rebuilding? The bearings are timkins, and don't look bad to the naked eye but under closer inspection look like they have work through the case-hardening. So i thort sod it and threw it all back together only to strip two threads out and possibly wreck the whole enterprise by over tightening the spring bolts and cracking the casting. At that point I thought curse word curse word curse word curse word curse word curse word curse word curse word curse word curse word, and came in. Now I have to confess to you lot what a humungous idiot I've been. Rescuing defeat from the jaws of victory. Dan |

Ah that sucks, these things happen! I've bought a couple of spit diffs recently, it seems the expensive bits are the CROWN wheel and other gear bits inside, cases are pretty easy to come by on ebay and cheap. You do need to add shims to each side of the bearings, it'll be unique for each diff. There should be a small bit of play but not much. I used this article when I rebuilt my vitesse diff, ignore the lsd stuff but it has good bits on the shim things richyrichracing.com/2019/04/triumph-spitfire-differential-rebuild/ You can buy shims from rimmerbros or Canley classics for not too much money, I got a selection to help. DM me and I'll post some to you if you want! |

I did have the diff in the vice as a stand in for the diff spreader and got nearly all the shims back in, there's 2 that didn't make it back in. with no noticeable sideways movement. To be honest it sounds quite nice there's not much backlash, if I was under a car and felt it I'd not be worried.

I have another diff sorted, off a 60k car apparently.
Still looking for 15" wheels as the previous ones got sold before i could close the deal.

Not much to report at the Mo, I have bought the 60k diff, and it appears to be in fairly good condition (This time I got someone with more knowledge than me to check it) which has put a dent in the hobby car fund. I've spent the last week getting an injection in my back and getting the tow-bar fitted to the CRV and other weekender prep.
I'm still looking for MGF 15" wheels, although my preference is coming round to the Minlite style ones.
