So after much deliberation i've decided to build Gordon Murray's first F1 car, the lovely Ceramics Pagnossin sponsored Brabham BT42. I'm thinking Reutemann in Spain where he nearly won on the car's first outing. I'll give some more history in due course.... This is the lovely casting by Simon (DNQ) and i'll be using a prototype Policar DFV for the engine top. Cheers Andi

I've never had much luck with making a white colored car look halfway decent. But I'm sure you won't have that problem. That's a nice looking shell; looking forward to your build reports Andi!

That is a lovely casting of the Cosworth and gearbox Andi, and the body is shaping up well too. Thanks for showing Nigel

Well i'm not hiding that the Cosworth is a very detailed 3d print. Soon it will be available as a scratchbuild 'spare'. The trick is how to use it with a brass gearbox... Yes well Mark if one worried about things like white paint before the build one would never gave got into scratchbuilding... I too have had some bad moments with white. Lets hope I can pull this off.

So a little progress First thing to clean up and dig out unwanted resin using my scalpel. From this: To this: Then just starting to look over the general proportions to see what needs to be modified and what might be left....

So the last photo above showed that the proportions might not be quite right! So after more research I decided that although the side pods didn 't need to be shortened the nose needed to be lengthened.... After a bit more trimming and cutting out we are here:

We edge forward slowly finding a few minutes here and there... The main body is fixed back to the nose with steel and brass dowels very carefully drilled into the thickness of the shell. The lengthening is achieved with u shaped plasticars pieces. The tricky bit is gluing. As soon as you have the glue in one hole and slide the dowel in there is no time to get glue in the other hole and then force it all together. Carefully applied brute force was my answer....

A bit more progress has been made to get the nose looking right... And just measuring up the motor positioning: One of the problems of this stage is that there is still a sense of going backwards!!

I've designed a brass motor pod to coordinate with my DFV. Its called the Rowland BG400. It is extremelly small and should disappear altogether: I've also realised by limiting chassis width i've shot myself in the foot as I can't use the side pods for chassis and pid fixing so i've had to invent a new method.... More soon! Andi

So, is one for sale?

Hi Andy,
If you do "go into production" on these it may be a good idea to machine opposing motor mount holes, and maybe horizontal hole as well so that a small 030 can, a 050 can and a mashima size motor can all be used. Any maybe holes for wing struts, and/or dummy transmissions.
Just a suggestion:)
Great bracket though.

Mark, two to cover the Ferrari 312b3 entry although i was thinking maybe of a 1960's car if i get an invite for next year.....
Chris, i put pilot holes at opposing corners that could be drilled out but in the end didn't do horizontal ones as my 030's have the same corners as these. What are the centres of horizontal holes? They may not actually fit this thing is so narrow.
Thanks for interest! Andi

Holes in all 4 corners for standard FF050 and/or FF030. I don't think that you'll have enough brass support if you then punch in horizontal holes. But don't worry.. Chris is the only guy who uses Mashima motors and the Pioneer Hurricane motor is never going to come to market so it's not like you're going to lose much market share.

Ahh yes 8mm will work. I'll put it into BG 401!!
