Time Attack/Circuit Racer Mitsubishi Evo V

I've been tinkering around with models again and I've had this kit sitting in the closet waiting to be built since the Southern NNL Nationals this past November. Finally decided to have a go at it. This is the first model I haven't completely planned out ahead of time, sort of coming up with it as I go.

The overall plan is for this to be one of those crazy Japanese time-attack/circuit racers that you see in the unlimited classes with completely redone suspension and drivetrains. I'm starting off with the tube chassis out of brass, the skeleton of it all.

So lets get to the pictures.

After building the main hoop I had to machine some control arm mounts for the rear. I'll be incorporating a double wishbone rear suspension similar to that in the LMP cars.

Here you see one finished "bulkhead" and one thats been machined. I decided to use files to perfect the final shape.

Several hours and lots of filing later...

This is my first time ever doing any major soldering, let alone a tube chassis. My hat is off to those of you building brass chassis, or doing any brass work. This is frustrating!

And there we have it! At least for now!

Enjoy!

Wow! Excellent soldering job on that frame! :thumbsup:

There isn't any new progress, but I thought I'd post a couple pictures of the chassis in the body at this point.

Can't be!!! What do you think you're doing building models!! lol...Looks amazing Mod I mean Mike! Is that fujimi body?

:eek2: ...Oh, Mike...

I've subscribed to this one - can't wait to see it unfold.

Great job MIke, glad to see stuff from you.
Do you use "FLUX" to help the soldering action? You'll use much less solder wire witth the help of the flux, with obviously less filing then.

Good to see you building again Mike, and a great start!

Thanks for all the kind remarks!

Yeah, its the Fujimi body.

Hey Gio! Yeah I've been using flux. Some of the joints I've used a little more solder on so when I add more pieces and those joints heat up, they dont fall apart. Still quite the challenge though.

Wow, cool idea, love the tube rear end. I love those time attack cars, some are just so extreme and all for 1mintue of glory. Cant wait to see what you do to the body

Mike's building something! :runaround:

I'm watching, Mike. Please keep this one going.

Today I started to build the floor framework. On the passenger side I made a raised tunnel for the exhaust.

Here's the pics.

Here is the framework for the raised tunnel. I used angle brass to aid in securing the brass sheet.

Hi Mike,

great work on the metal frame

Just a question: wouldn´t be easier to make it with Evergreen stuff?

wow, just wow. im sure he could use evergreen, but you won't be able to get those crisp bends that you would w/brass. looks great bro, is there gonna be a monster 4g63 under that hood??

Hi Mike,

great work on the metal frame

Just a question: wouldn´t be easier to make it with Evergreen stuff?

Styrene would be a lot easier. In fact, I am building a lot of the bends and stuff out of styrene first to use as a template then bending it in brass. I chose to use brass for two reasons:

A. I wanted to challenge myself. I've seen brass work done by several fellow modelers and have always been impressed with the way it looks. Something I've always aspired to do.

B. Structural integrity. I've seen people build styrene chassis and stuff before, but I've always wondered what happens in a couple years, is it drooping? Plus the suspension perches can be a lot stronger in brass and much smaller without compromising strength.

Thanks for the kind remarks. I won't be using a 4G63...I know this is sort of sacrilegious but I'll be using a 2JZGTE. :iceslolan

What,..... a Toyota Engine in a Misti? cant wait to see what that looks like!!!
Nice brass work

I agree in both arguments, it looks convincing, a modeller sometimes needs to be challenged and it probably will stay longer than plastic.

I spent a lot of time today working on the rear end and started the roll cage. I'm approaching a bump in the road as I haven't figured out how I want to do the front suspension yet. (I suppose its time to look up some racecar reference!) The rear end is almost complete. I still need to build the wheel wells and add a few more tubes. The cabin area is just being started.

Somebody had asked how I jig my parts up. Most stuff is held in place by fit, some of it is held by reverse action tweezers. This is a more complex jig setup to hold the control arm bulkheads. I used a 1/32" drill bit (solder doesn't stick to tool steel, drill bits are cheap, and I had one laying around) through both bulkheads to insure they were lined up correctly, then the tweezers are holding the bulkhead in place ready to be soldered.

More pics of where the project currently stands.

The body fits the chassis like a glove. Couldn't ask for a better fit.

You're telling me........

Excellent stuff!!! :runaround:

That's crazy... and I love crazy :grinyes:, brilliant work!

WOW, I`m speechless, have you pics from the real car:eek2::eek2::eek2::eek2:

Excellent Mike, excellent...

Did you start from a drawing for the tubes layout, or are you assembling them directly onto the car?

R :)

ill be waiting for this thread.. it would be the detail.. nice car man!

Thanks Robi! Surprisingly this is the first model I haven't thought out and drawn out ahead of time. I'm actually just coming up with it as I go and fitting it to the body. However, I do occasionally use styrene rod to bend templates, such as for the front downtubes.

Nice!!!!
I have no clue about that sort of car but your work on that frame looks waaay promising!

Looks really excellent...
Can't wait to see more update from this...

Holy mother....! How did I miss this?

I don't know what's more astonishing, the fact that Mike's building something, or how fantastic this is going to be! Stellar work so far on the tube frame. What an amazing car this will be!

Stunning work, I have always wanted to do a brass chassis, and you sir have rekindled my love for modeling. I think I will attempt a shot at a similar project.

love it keep it coming
Steve

Thanks for all the kind remarks.

Thanks for the compliments jaykay, I'm very inspired by your work!

Haha, hey Will! It is rather astonishing that I'm building something! Thanks for the compliments!

Wow!

Very nice intricate work there !

I've spent some time designing the front suspension geometry, which I have of course overcomplicated. Instead of the standard vertical strut in the front I am going to build a double wishbone push-rod suspension typical of F1 and LMP cars. I spent a lot of time planning on paper and drawing in 3D SolidWorks before doing anything on the front. Now I need to machine 4 more of those control arm mounts.

I have also done some extensive work on the cabin/rollcage area. The roof structure maybe be familiar to those of you into WRC. I have used some smaller diameter tubing for a lot of the secondary supports similar to the what I'd do on the 1:1 Cages I've built. I also started the floor pan using .015" Brass sheet.

One thing that I've found quite amazing is I have used 13ft. (4meters) of brass tubing so far, and yes, it is 1/24 scale.

Enjoy!

:eek7:

:eek2: :eek2: :eek2:

Wow!

:worshippy

That is still brilliant :p!!!

AWESOME! Where do you get your brass rod?

Looking good Mike! I pulled out that scratch built "tire" that you sent some time back for me to look at, and wondered if you had been building.

Just a quick update of tonight's progress. I've started working on the wheel wells. I used .015 brass strip for the wheel wells. I annealed some .032" Diameter rod to simulate bead rolling. You'll notice that the insides of the well are missing a giant square chunk. This will be filled styrene since it needs to have holes for the control arms and suspension components to poke through, styrene is just a lot easier to cut to that level of detail instead of brass.

http://img198.imageshack.us/img198/8692/img9297.jpg

I do need your input though. I'm not sure if the bead rolling is out of scale. I keep think its too big because I know mathematically it is too big and I am extremely tempted to redo it. Here it is apart of the frame, I'd like to hear your thoughts.

http://img191.imageshack.us/img191/7931/img9302.jpg

http://img189.imageshack.us/img189/897/img9301.jpg

Truly awesome... excellent craftmanship !

(and very nice photos) :iceslolan

Robi

The bead rolling does look a tad big. What are you planning on painting the Chassis with? If its a paint that is going to spray heavy, it will probably come out looking perfect in the end

great work, I`m impressed :eek2::eek2::eek2:

Thanks for the kind remarks!

As some of you know I am a perfectionist, this can be seen in redoing the wheel arches. I removed the bead rolling and then I actually trimmed the wheel arches to make them a little smaller. I then resoldered everything and added some .020" rod to simulate the bead roll. It still didn't look right. I then removed the .020" rod, and then soldered some .015 rod which did the trick. I also went from three bead rolls to two.

http://img198.imageshack.us/img198/6625/img9319.jpg

Here I've laid the original wheel arch with .032" bead rolls to the new wheel arch with .015" rod.


I have also completed a majority of the work on the frame. All the brass work on the main part of the frame is done. I really need to start doing a lot of styrene work to fit the body to the frame before I can finish the front end mounting for the bumper and headlights.

As you can see I've removed the hood using photoetch saws. The front portion of the body sits up on the wheel wells just resting on it. This will soon be taken care of by notching the fenders to get the body to sit flush with the frame to start the rest of the fabrication. Also note the markings for the new wheel arches.

http://img198.imageshack.us/img198/5854/img9351.jpg

I really like this picture, it looks mean with those massive wheel arches.

:worshippy this one is going down in the history as the badest 1/24 brass caged time attack beast!!

just one question, what do you use as a torch? is it a jewelers torch?

Mike, it's thruly fantastic.
I know you would like a less boring powerplant, but consider the idea of a full metal chassis+engine... would weight a lot :D
So... just send me your address ;) , I need another great beta tester :D

This looks really cool. You know, it will really be a pity to cover all that brass cage with paint :-)

Just what I was thinking...

You're insane ... or a genius: take your choise. :eek7:

I've finally had some time to focus on this project and start cutting open the the doors. I have also opened up the rear wheel wells. I had to open up the rear wheel wells before opening the rear doors to help with alignment.

After opening the front door I began work on the door frame which is built out of styrene. Some brass rod was used to aid in strength, particularly the b-pillar. Window frame sills were also added around the upper door frame on the body. The rest of the door frame is currently separate from the body and the frame, but will be glued to the frame later. Also note that the exhaust cutouts havent been made in the door frame yet.

I was curious to see what it looked like mocked up with a wheel and tire in the middle of progress. Note, I will not be using this wheel as it is too large, but the outer diameter of the tire is correct.

Thanks Jaykay, but thats why I'm taking progress pictures! :biggrin:

Mike,

Excellent work on those door frames! You are still the king of scratchbuilding

:eek7: :eek: :eek2:

This is awesome! this has got to be one of the coolest projects I've seen on here.

what are your plans for the body? you know what color your going to paint it?

And when is the next AFMOTY...?? :naughty: :naughty:


Simply unbelievable master work...!

Looks fantastic.

It's good to see others working in brass. It's such a joy to work with.. i adore it.

I hope your project will spur more people to give it a try.

Wow. Stunning work! A lot of real race cars don't have this extensive and careful prep work. The brass cage is amazing. But you know I'm a lover of plastic, so I find the door frames, particularly the B pillar, just beautiful. Can't wait to see more.

wow this is crazy

:ylsuper::meant::bananasmi:eek2: Im speechless..... You have amazing skills i envy your talent.....
