very,very great build

[ll Brandon ll]

I was legitimately sad when I hit the last page of this thread. Your building skills are FAR beyond anything I can ever hope far, but my God is it awesome to watch! Keep up the amazing work and I really hope this car sees its finish.

Question, what would you charge to have an engine printed out like your prototypes for sale?

This is incredible! Just found this through an other thread! And damn! Your skill and tools are awesome!
Anny more updates on this beast?

Hi Anton, thanks for your kind works. There have been updates, I was waiting to have some more substantial work done worthy of posting before I made an update.

Here is an update anyway:

I have been working on the seat buck to vacuum form the seat shell over.





To vacuum-form the seat, I have to cut the seat in half and vacuum form each side separately then piece it back together. There was too much draw for the sheet to form it in one piece it it was causing a lot of webbing.


This is my homemade vacuum-form that I made for less than $20.


I dusted the seat plugwith talc so that it was easier to separate from the vacuum formed plastic.


Here the .030" (.75mm) styrene is clamped between two 6mm pieces of birch plywood. This what will go in the oven at 350°F (175°C) for a few minutes. Once the plastic begins to sag, its almost ready to be formed. The clamping jig is pulled out of the oven, placed over the vacuum form and then the vacuum form is turned on. I wanted to get some video, but vacuum forming by myself is difficult enough!


After the plastic is formed and cooled, I pulled the seat plug.

After many failed attempts, and trimming later the seat is starting to take shape. Still a long ways to go.









Next I will finish trimming the seat and begin detailing.

I have also spent some time refining the body work. This is all prototype, the final body will be vacuum formed over these parts so the panels are the proper scale thickness. I've also cut up the hood for the radiator/intercooler duct work. Lastly, I added my signature dayglo yellow wheels.











Enjoy!

Keep it up Mike! I cant wait to see more of this one!

I think you are missing the wheels on the passenger side.

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??

It's starting to look like a real car! Great job. Just awesome.

PS--I didn't realize that was you (didn't make the connection again) over on the RB6 thread. I'm sorry, man! I swear kids kill brain cells, so beware!

[gionc]

Mad man! You were almost teenager when you started , I'm wouldn't be surprised if you finish it with a squadron of grandsons doing mess with your colors and brushes

Damn, this would be the longer thread I follow

Fantazzztikk like ever!

Dunno what Mitsu is this (DTM new car maybe ) but I love it.

[willimo]

Woah this got really interesting since the last time I saw it! This is stunning work!

I like the low tech vacuum form. Thanks for sharing.

This weekend I started working on the timing belt cover that mounts to the front of the engine to shield/protect the timing belt, oil pump drive belt, and also houses the water pump. The timing cover will be machined out of 7075 billet aluminum in two pieces, which will be bolted together. The design is not based on anything that exists today, just based off of what I would design if this were 1:1 scale.

The first step was to start drilling the holes around the perimeter of the first half to assemble the two halves once complete. The hole diameter is .012" (0.30mm).


I was very nervous drilling these holes, since I have never drilled into aluminum with such a small drill bit. Lots of cutting fluid was used.


After drilling the holes, the part was roughed out using a .125" (3mm) end mill.


Detail work was done with a .03125" (0.79mm) corner rounding mill. The radius on the mill was .010" (0.25mm) to replicate the radius fillet that would exist on a 1:1 part.


After the piece was machined, I needed to remove the remaining material on the backside of the part. I don't typically enjoy doing this method, but is reliable; and after 12+ hours of machining I didn't want to screw it up!

I machined a plate of aluminum with a pocket in it that was the exact size of the part. I held the part down with a step-clamp and then machined away the remaining material with a .125" (3mm) end mill. Once I finish one half of the part, I unclamped it, turned it around anf machined the other half of the remaining material.


Finally the piece is finished, and I am extremely pleased with the final result. You can see the three bosses for the timing belt pulley's/tensioner, crank shaft bore, oil pump bore, and then the housing for the water pump impeller.






I decided to mock it up on the engine block to see how it looked. Keep in mind that the crank shaft journals on the engine block are not finished yet, so there is some overlap that will be removed.




I also did an experiment this weekend that I was not sure if it was possible for me to do. I tried engraving for the very first time. Here's a teaser of the experiment for whats coming up soon!


Thanks for looking, enjoy!
