Hi everyone, I hope we all have had a good and festive holidays and the food hangovers (or proper ones lol) are dying down lol

Well after a long absence I am back, had a new change of job so I'm basically back to school at the moment so not able to hit the bench much. However that being said I have managed to finish my little jeep which I need to upload all the pictures for and have just started on the this little bad boy.

So my best mate races in a amateur motor sport competition in the BRSCC Mazda MX-5 cup. so to that end he has been after a model for his office. So as he been after one for over a year I decided to treat him to a customer made model for Christmas.

With not having time to get it built before Christmas I decided to give him the kit unmade and tell him to use his imagination lol

So this is what his car looks like.



Now luckily the kit comes with no roof so winning there so far, however I now need to some how make a custom roll cage, wheels and decals for this. So going to be pushing myself out of my comfort zone for this one.

Also if anyone knows any decent materials to use for a roll cage and wheels I'm all ears. Also does anyone do custom decals???

Anyways the kit itself. Old Tamiya kit, however it'll do for this.



Look at how few parts there are!!!



Got the primer out, usual Vallejo black and white for the chassis and white for the bodywork.





Need to get the roll cage sorted for the tub then I can get the seats etc in. But that's for another day.

Enjoy and Happy New Year for this weekend!!

If you can do some soldering I would suggest using thick copper wire for the roll cage. There are some cables for high currents which are one single solid copper rod.

Does the copper rod come in 3-4mm diameter because looking at the scale that is about the thickness I'd need??

I think you could find that kind of heavy cables in the automotive business
Google for 'single core automotive cable
Sometimes they are used to conect batteries and high power amplifiers ...

Copper round stock:
https://www.amazon.com/Copper-Unpolished-Finish-Standard-Tolerance/dp/B00CNLWP3Y

0.125 inch could possibly be something
available in 12, 24 and 36 inch lengths, 12 inch costs $ 6.84 + shipping

If they are too hard for easy bending/shaping as delivered I think you can heat them with a butane flame to soften them.

Good luck & Happy New Year

Cheers Robin, that should do me good. Need to work out which size would suit best.

You could also buy round styrene rod and work with that.

Bending styrene rod to smooth curves is a bit more difficult than working with soft copper. Styrene tends to crack and split instead of bending nicely.
