    Or Angle cuts as well (if it has a turntable?)

    yep it has an angle vice thing..though at this point even straight cuts would be an improvement 😉

    Carried on with the (w)underbar today – mostly just measuring and mocking up the first cross beam and making sure it’s all level. It needs a little adjustment but only once the cross beam is attached so it all stays lined up. It’s gradually taking shape though 🙂

    This was first time out with the new chop saw and whilst it seems to have some limitations (mostly due to some disc “wobble”) the cuts are noticably better than freehanding everything with the angle grinder. It got dark before I could get much further but the fit of this cross beam looked a LOT closer than any of the previous joins.

    Hopefully pics tomorrow if it’s not chucking it down…

    More progress today, got the first couple of cross beams tacked in place and so far it all still fits!

    I was planning to just have one vertical beam in the middle (along with one on each side) but the bit where the chin panel bolts on juts out more than I thought it did so we’re going for a total of 4 verticals…a bit more cutting but no biggie, and might mean I can use slightly thinner sheet to bridge the gaps (or something).

    The centre verticals are just clamped in place in the last pic (hence the great big bit of angle iron to keep things aligned) but they look to fit ok and will get tacked in place next.

    Once actually under the car the “longwise” sections (i.e. the continuation of the verticals, in line with the car) will need to deviate from equal spacing to allow clearance for the sump, gearbox etc but there should still be plenty of bracing to ensure it’s nice and study for when I grind it over kerbs, rocks or whatever 😉

    finally got to do a bit more work on the syncro…hopefulyl more tomorrow too \o/

    Started getting the in-between bars welded in place. Unfortunately I used up much of my metal stock on other projects recently so will need to add more but am hoping to get this wunderbar wrapped up shortly.

    Next up is a new downpipe since the current one is blowing at the manifold flange and I feel like this might be a good opportunity to practice my TIG welding 😉

    got the next set of intermediate bars on the Wunderbar tacked in place and got the first tabs onto the front bumper section so now it holds itself in place…

    I’m awaiting more tubing to do a bit more cross-bracing and then hopefully add some nice thick ali plating and we’re done \o/

    so it turns out I might have found out why my downpipe was smoking…there was no gasket between the exhaust manifold and the downpipe flange…so that possibly just saved me a shitload of work \o/

    guess I’ll have to practice my TIG welding on the sump cage/Wunderbar then…

    So the Wunderbar mock-up construction is done (pics are MIG’d tack welds) and I spent much of this afternoon working on the finish welding to practice my TIG work, and it seems to be coming along nicely.

    I love the level of control you get with the TIG (using the foot pedal) rather than the more “point and pray” approach with the MIG, though the extra set-up time is a pain in the ass…in most cases it’s meant the welds don’t even need dressing. I’m not quite up to the standard of being able to do consistent “fish scale” welds yet but a few of them are in that ballpark, and most of them are just smooth which will do me nicely for the moment 😉 Will post some pics when it’s daytime (it was dark by the time I finished today).

    got it all back together again now with an exhaust gasket and the fecker won’t start. Not sure what I’m missing though i did find out that a couple of the plugs were loose before (when it ran).

    Am awaiting some starting spray so I can see if it’s a fuelling issues, tho the plugs seemed wet and there’s spark….so not sure what else is wrong. ugh

    I guess being up on ramps meant that there was no fuel getting to the engine…put some more fuel in and it fired right up \o/

    There was still a teeny bit of smoke leaking from the manifold/downpipe join but I tightened the bolts a bit more and it seemed to stop. Might have to have another go at those bolts and try to make sure they’re *super* tight to make sure there’s nothing seeming out. Failing that perhaps squirt a bit of exhaust gasket sealant type stuff in there though obvs would rather not have to take all the inlet stuff off again.

    There was still some general smokyness from that part of the engine bay but I would imagine that was left over WD40 or engine oil since it didn’t seem to have a specific source.
