Trust me, I will choose some very random colour to paint it

Its gotta be a real 70's colour

Something that not many people would probably choose

But it has to be cool enough that when posed on the front lawn I can't help but go #### yeah

1am the other night, on a mission

I do know that there are some heat resistant Stainless steels out there (cant remember the specs) but even they failed on the bikes.

It would be good fun to build 3 chambers for each cylinder as the 3 into 1 wont be doing a great deal.

Do you know the port timing, RPM range, head volume and cylinder CC?

Cheers man, I love talking expansion chambers!!!

Not many people can get their heads around them

In a few months or so after getting it legal, I will go there with the expansion chamber, I have the design and measurements for the aftermarket off the shelf chambers that you can buy in Japan, they are set up for top end. It would be real interesting to go through the science and see if it can be tweaked to better suit what I use it for.

If the design is good, it may be just a case of shortening the distance from the lip of the exhaust port to far end of the deflector cone.

If any one wants to do some reading, here's one of the best articles on expansion chambers I have ever come across. Its old skool, and to the point

I'm open to anyone else's opinions on them too of course

Paint it this colour. It's definitely 70s!



I reckon it would look awesome

So I googled 70's 4wd paint job images and this seems to be the norm for that era................



also googled just 70's paint job..............

The main problem being you need to be stoned to fully appreciate them (actually they do look pretty cool)

two tone, Orange and Beige for my money

Been a bit slack with photo's this weekend, it sort of disappeared on me

On Friday night I got the out side of the tub finished and coated in Hi-build primer. That's ready for a rub down with 200 and the 400 grit paper just before painting.

On Saturday I managed to get the inside of the tub completed. I masked off a whole lot of parts I didn't want to get covered with Raptor liner, and then let loose with the gun. I followed that up with a dose of gloss black to certain area's to bring the bling

Finished result looks good.

I also made a start on the bonnet and guards, and finished them off tonight. The bonnet was a bitch. It was rusty and badly dented. Its is now slightly less rusty and a bit less dented. Its not mint, buts its presentable

I grabbed some quick pic's tonight for a short update.

Front clip mocked up, with guards fitted. Made dressing the top of the guards easier:

and hiding under the cover keeping the dust out......


Is a finished interior. Looks good, hope the liner lasts for a bit


The bonnet after a few hours of shagging around with a hammer and dolly, carefull work with a sanding board and three or four attempts at dressing the center raised part to it somewhere close to the right line.

It looks promising after a coat of epoxy primer!!! Maybe it will look straight enough after all

The guards are finished too. They look good with the under side coated in raptor liner. Here's to hoping it stays on for a while.




Next up are these two:

The saying of the weekend has to be "rough enough"

if i have said it before i will say it again, Petes Rough Enuf is generally mint to us mere mortals!

But red = faster and you need all the help you can get in a zook

Sanding high build primer is GHEY

Sand the entire truck with 220 grit until smooth......

Then go over the entire thing again with 400 grit until REALLY smooth.......

Then go over it again looking for the bits you missed

I'm feeling your pain... lucky mine is just a bush truck and I stopped at a rough 220

I'm still sanding 2pac with dull 120
your miles ahead of me.

1:37am Friday morning, sanding complete

good effort mate

DieselBoy wrote:1:37am Friday morning, sanding complete

Dude, you have an illness... 1:37am Suppose you are going to work today too?

That is commitment right there, no wonder you get stuff finished so quickly.

Good stuff

No work for me today

Following the 1:30am finish after sanding everything 3 times, it was a 7am start this morning.

I got the call on Thursday afternoon that there was an opening in the schedule at the panel shop and the booth was going to be free for the day on Friday if I was ready.

I was no where near ready as I had been out of town working, but wasn't going to pass up the opportunity, you gotta grab these things with both hands!!!!!

I shuffled my work round and managed to get the Friday (today) off work, grabbed a stack of sand paper on my way home and HIT IT. Solid sanding, 5:30pm through to 1:30am on two Burbons and a packet of corn chips

This morning I had to bolt the body to the chassis, load all the parts into the van, push the Wombat out of the shed and winch it on to the trailer. Hard work all by yourself

Once at the shop, I went over everything again with 400 grit (4th time over it all ) and had to draw the line at that. Its not mint, but good enough for a rough job in my dusty ol' shed.

All ready for masking up:


Swapped places with the Coon and heaved it in to the booth. Let the blinging begin






Layin down some colour:


Can't wait to it out in the daylight, the camera's having a hard time with the freaky colour



Head down to the shop to pick it up tomorrow morning as we decided to leave it in the booth over night to cure properly. It's going to be hard to sleep tonight

Now it can start to go back together, all the black detailing that's ready to go on is going to look mint

LOVE IT cant wait to see it in the flesh in a few weeks

good colour choice i say,will definitly stand out from the crowd

what was Dan drinking to deal with the colour

Gotta love green Hangin to see tomorrows pix without the masking

Nah, just co's it was Friday morning smoko

It's way less bright lime green and more khaki/olive than the camera would have you believe

Looking good...

You'll be wanting a set of mirrors like on the one here... http://bringatrailer.com/2011/11/06/sire-of-samurai-1972-suzuki-lj10-jimny/

Wouldn't mind the soft top and doors too

Hundreds and hundreds of little jobs, but getting there.

Sifting through box's of parts choosing the best, scrounging some parts from this and a bit from that to make something that works, tapping out the threads in captive nuts filled with paint, what wires went where, is that wired up right or does it just not work?? I have four of these, which one is the best?? Arrrrrg

The main things left to sort out are:

the steering so the wheels point straight ahead,
the carb to clean again as the idle circut sounded like it was bloked on the test run a few months ago
fuel pump to sort out (make one out of 3 or 4 shitty ones)
Brake hoses to source
Rear wheel brake cylinders to source, I have none that are any good
Brake system to bleed and test
cooling system to piece together out of parts collection
windscreen wiper system to piece together from the junk collection

Then there is the roof and doors and roll hoop and rear seat and front bar and rear bar and flares and winch and radio and stuff

But at least it's starting to look like a truck again Any idea how hard it is to capture its awesomeness in the garage with a camera, can't wait to get it out in the natural light on the front lawn

A bit of shagging around with caburattors and fuel pumps the other night.

I managed to make a fuel pump go, but its only working half as well as it should be due to a spring on one side of the diaphram being wrecked. Rebuild kit from Oz I guess.

The carb was interesting, I have always had issues with the carb on The50 having a really sensitive idle jet. It blocks up all the time as the hole through the jet is TINY. I took one of an engine I've had for a while and gave it a scrub:


It had this cool little gauze filter before the needle valve into the float bowl:


It fits in here:


I bet it keeps the idle jet clean for longer

So after a bit of playing and checking, it was time to turn the key

I had the control leaver on the CCI pump cabled tied full open to purge any air out of the system and get plenty of lube in seeing as the motor has sat for may years.

You know its getting plenty of oil when it starts running out of the exhaust and makes a pool on the ground and then sprays oil all over the wall





The first drive is getting pretty close!!!!

ringa ding ding ding
Sounds gooooooood!
