David Looking great, I am glad to see someone else working on their cars as I fear many have left it very late to take part in next year's epic world championships!! (that's a hint for those who haven't begun their builds in earnest yet)!!!!!! Andi
I'd be done by now if it weren't for the @$%*ing wings.
The what wings?? he he.
Seriously though I quite enjoy the wings... post some pics!

A few more shots of where I've managed to get to. The rear suspension is now complete although it needs a bit of cleaning/tidying. I will quickly point out it is a bit of a compromise to accommodate the crown gear/motor bracket and leave room for covering it with a gear box casing. Its also quite a tricky structure to replicate as the suspension was supported on a tubular frame. Oh well it looks reasonably convincing as long as you don't compare it too closely to a drawing or photograph! I've also made the exhausts (subject to a bit more filing and smoothing) out of aluminium wire and tube. This is the first time I've tried this method so I hope it works out when I come to fit them to the engine block.
Next on the agenda is making the rear wing and its supports - another tubing structure on the Tecno so Andi's how to do it guide is going to be really useful!

Here is this week's work on the Tecno. The rear suspension is complete and the wing structure has been added - many thanks to Andi for his tutorial on how to make and attach a wing, its been invaluable. The wing itself is still under construction from plasticard, part of an old asthma inhaler casing and aluminium - unfortunately the Zolder Tecno had mid-wing, vertical plates so there's a bit of trial and error going on regarding how to fit them to the wing. Whilst I decide on that I've been making the front suspension which is slightly tricky as it was fabricated out of tubing. The lower wishbones were fine (no photo of these) to make and attach to the chassis. The upper rocker arms have been another matter and I'm indebted to Mark for suggesting a jeweler's honeycomb soldering block for keeping everything square and in the right position. After a couple of false starts I now have two rocker arms which bear a passing resemblance to those of the real Tecno and also just fit into the cut outs in the body shell. In the picture below the rockers still have some lengths of rod attached as I haven't decide how best to attach them to the chassis/front axle as well as making sure they line up properly with the body.

Well this is shaping up to be a real masterpiece. Brilliant job. For some reason I really like the line of this car. Not beautiful but somehow beautifully put together. Amazing replication of the details.

Well the front suspension is complete and installed which more or less finishes the rolling chassis apart from a bit of cleaning up (the pictures reveal the necessity of doing that!). Incidentally the brass front axle tube will be trimmed to length. I can now attach the wing, finish the body preparation and detailing, and fabricate the engine and gearbox. Then onto painting and fine detailing. Sounds simple!
I agree with David L, that you are capable to create your own bodyshells in resine. Yes, I believe this. Its difficult, but not as difficult, as it might look like. And believe me, it will give you lots of fun! (take my Matra for an example)

Another progress report. Today I've been working on the engine and exhaust details. I have constructed an aluminium support (which will sit stride the motor) for the injection system, cylinder heads and exhausts which I may extend to act as the cockpit sides. The injectors are ferrules with fine mesh inserted (see photographs below), the cylinder heads and mounts for the injectors are in plasticard and aluminium. The exhausts are also aluminium as shown in a previous post. Everything is glued together either with Gorilla glue or epoxy. Yes it all looks a bit rough at the moment but a bit of cleaning up and some paint will improve matters no end!
Note the tubing towards the end of the pipes is temporary to hold them in position whilst the epoxy glue sets - although slivers of the tubing will be used eventually to form part of the exhaust support brackets.

This thread keeps getting better and better as you share progress on your Tecno build. My only concern is that you might go over to the dark side--those angular 70s cars with struts and wings--and never come back to the place where you belong--the sixties. Don't you just love how I've decided where you should be?
You might have done me the favor of starting this build a few months before I went through a few feet of brass tubing as I struggled to construct some Ferrari exhausts. Ah well, thanks to you, I'll know better what to try next time.

JHere are two photographs of the Tecno: after the cylinder heads and injection trumpets have been installed; and of the first stage of mounting the rear wing. I've added the underside of the wing this afternoon and the mid-wing plates but it looks a bit messy at the moment as there is filler to be sanded down so I haven't photographed that yet! The radius rod mounts have been fixed in place and and the driver head restraint has been added to the body. I reckon its not far-off being primed and painted now - maybe next weekend?
