11 months later...... Oh, my. As George Takei might say, it's been nearly a year since I updated this thread, which means it's now been somewhat over a year since I bought the old XJS. Predictably, the project has been ambling along gently, with work occurring in fits & starts. The car is now completely stripped to a bare shell - no wiring, no ancillaries, absoluetely zip. All the glass, doors, removable panels are all off.... and now the state of the shell can be seen in all its horror.... and yes, it's pretty rusty. The 2 pics show the chassis rails under the nearside rear arch - this section of chassis will be taking the full brunt of any acceleration and hard cornering, so it needs to be rock solid. Not mostly made of iron oxide, as it is just now... |

So, several happy (ahem) hours later, and I've scraped most of the underseal off, and used one of those rusty metal bashing air tools to knock out the holes to their full extent. Pics to follow. Ah, underseal scraping. Probably the second worst job in the world ever..... the worst being, anything your Mum told you to do when you were 10 years old... |
| AdeV:
Meanwhile, over on the engine bench, the manifold adapters are starting to take shape. As ever, a wax prototype is called into existence, it's cheaper than trying in aluminium, and if the tool paths go a bit awry, you don't damage your cutter.... It's not really visible in the finished item, but the left-hand intake hole actually started cutting half-way down - a 10mm plunge which would have destroyed the cutter bit or the workpiece - or both - had it been aluminium... |
| AdeV:
There's a bit more to do on those adapters yet - there's another "layer" to go on top which will hold the ITBs; the two layers will then be bolted together. The reason for all this malarkey is, the bolt patterns of the Jag head & the BMW ITBs interfere something chronic. A single piece adapter is not possible because the Jag head bolts interfere as well. It's almost like it wasn't meant to be... ...but by 'eck I'll make the damn things fit. Obviously the final version will have smoothed & gas flowed profiles; depending on the flow testing (bench is on the project list), the final shapes might end up being hand-cut rather than CNC machined. 2 pics showing (approximately) how they'll be installed. Note the new distraction in the corner of one of the pictures.... |

Ade, You've been busy. It looks as if you have much more welding to do than me. How are you doing it, MIG TIG or gas ? Dave. |
