ULTIMATE SCRATCHBUILD: 1:12 Hot Rod-Updated 03/12/06

[mike@af]

Whats new?

This afternoon, homework permitting, I will work on making the first jig for this project. The jig will be uses to cut the C-Channel in half evenly. The C-Channel I bought (4040Aluminum) happened to be 1/2"x1/2" with a 3/8" channel. I need the C-Channel to be 1/2"x1/4" so I will slice off a quarter inch on the the "open" part of the C.

After cutting the C-Channel, time permitting, I will create another jig used for cutting special angles, technically its a miter.

So I think this project will be much better off with the planning and thorough design of it. Especially with so much time put into designing to make sure everything is perfect, and creating proper jigs for accuracy and symmetry.

Hopefully within 2 weeks I will have a god bit to show at the next ACME meeting.

Wow, Mike you went and turned all professional design scale modeling on me.

Awesome project and it shows how much dedication and discipline you have.

Heck I gave up model cars before I even got started, because I wanted cool looking rides w/ lowered suspension and custom wheels and didn't want to spend that amount of time for (wheels suspension mods).

I just got back into modeling because I have like 10 kits in my closet and I figure I just build them stock now.

You take care.

I will be watching your build.

not bad mike. if you can make this one and habe better luck. well i give you lots of credit. i am likeing how you are starting with a chassis. you should have started with a chassis for your old 1/12th scale car but now you know what to do the plan look better you might pull this one off

Thanks Bryce. The last project I didnt start off from the ground up was because I was going for a specificly defined look that could not be put on paper, only metal. I figured I could design the frame around that. I will pull this one off, I am determined.

UPDATES:

Well, this is not the most enjoyable part of the proccess, cutting 1/4" off the sides. Made a jig, that wasnt so bad. Began to cut. 3 hours later I have cut 5 feet.

Now the cleaning proccess begins. The cuts are a little "wavy" so I need some way to level them out. I started with a file, 45minutes and I havent gotten anywhere. So I busted out the Dremel, that wasnt a help either. With a rough sanding wheel, I was able to "clean" and "smoothen" 6 inches and the bit was destroyed.

Any suggestions on cleaning up the cuts (leveling them out)? Im out of ideas, and dont really want to spend 45 minutes with a file to get nowhere.

Anyway, I know you guys are pic hungry, so heres a pic of the jig.

Mike, here's some eye candy. I personally didn't take these pictures. Adam, the guy who has the HEMI came to my house today and took some pics of the motor, I told him that you needed dimensions and this is what he gave me. Also, I have access to the motor, as I'll be caretaker of his cat until he comes back.

Full length of engine including from the tip of the header forward to the edge of the fan: 6'' inches

5 1/2'' inches from the bottom of the sump to the top of the aircleaner

4 3/4'' inches total widith (including headers)

1 1/2'' wide by 1 1/4'' long oil sump (just the sump, not the whole pan)

The block itself is 4 1/2'' inches long

These measurements he said, are given a little leway, so you'll know how big to make your bay for a ''tight'' squeeze. If there's anything else, give specifics so I know what to look for...

Ohhhhh yeaaaaaaa. Thank you so much man, I owe you one. I am going to go grab my designs and check the dimensions. Sounds like it will fit.

A specific I would like to know, what is the degree and size of the cams?

Gotta' go check the fitting, be back in ten to announce!

[86_SR5]

The cams...hmm..well, If I still had desktop dyno 2k, I could tell ya!

[pre98zetec]

I got that 1/6 hemi too. It's sweet as hell!

[mike@af]

Well Im lucky. I need to modify the curvature of the hood and top view of the chassis. It not that big of a deal. I need to add roughly 13/16" to give it roughly 3/32" clearence.

Hey 86,
Can you get me dimensions on where the engine mounts are, or would be? Like the width of them? And possibly take a picture of the bottom?

I really appreciate this, I dont want to get way ahead of myself and build it just to rebuild it to have an engine. The car is basically be designed around the engine.

hmm, do you have a die grinder? or anything like that? that could work. i have used a die grinder for similar things and made nice cuts. a dremel with a cut off wheel should work.

that engine looks great, i hope when you buy yours mike you chrome it out, and add more details! make it like a boyd style motor all chrome!?

[86_SR5]

He'd have to paint all the orange and black, because that's pre-painted. Mike....engine mounts. Im assuming you want to fabricate them, right? My guess would be right behind on the oil pan sump above the oil pan in about a (not scaled down) 2'' by2'' metal mount. This is purely guess.

As a matter of fact I might run to Lowes and look for better Dremel bits. I tried the cutting wheel but it was taking way to long. 8" in 30 minutes.

I will definately customize the motor. I will strip the paint (sorry Hemi lovers) and polish and chrome it. And detail what ever left possible.

Yes I will be fabricating some engine mounts. Just trying to get some ideas to see how deep Im in. How long is the oil pan?

If you dont mind, shots of the bottom of the motor would be excellent and greatly appreciated.

awsome chrome it out with alcalad II!!! that would be sweet, do some custom headers, and air filter ect....

Yea. I will grab some Alclad II #105 Polished aluminum and #107 Chrome. Im going to paint the engine block with polished alumium. I think brushed/polished blocks look really good. Also, that way there isnt too much chrome (yes there is such a thing).

Also I will need to do custom headers for it. The only thing that will slow the flow of exhaust is some scratchbuilt catalytic converters, screw mufflers.

Im not sure what I want to about the Airfilter though, maybe a Quad duce.
