1/12th Porsche 934 Vaillant


Recommended Posts

One step closer!  Installed the fire bottles permanently and ran some more lines. I used some hose that I had in stock and also some #16 and #14 electrical wire casing.   I stripped the wire and then cut the clear outer covering off of it which makes it more pliable.   Unfortunately, I just realized that the stamping on one of the hoses is visible and you can read the wire size!   Now I need to make two brackets to hold the hoses down.   After that I'm hoping to figure out where the hoses actually go.   All the pictures I have seem to show them running into the opening next to the fire bottles and then they disappear.

The hose clamps look great as does the under-hood tubing.

You should be able to remove the AWG stamp by using some lacquer thinner on a small cotton bud.

Thanks for the tip David, I will definitely give that a try!  Obviously i wasn't paying attention when I installed it, because i got the hose below it right.

I made two brackets for the electrical wiring and hoses out of sheet brass.  Used Detail Master nut and bolt heads on the brackets and glued the brackets in place.  I'm not real happy with the outcome of the brackets, in retrospect I should have used some of the RB Motion nuts and bolts I had in stock.   On the real car the brackets are longer and flatter, but I was really constrained by space.   The four hoses were supposed to lay side by side but I had to stack them because of limited space.  Luckily once everything is installed the brackets won't be quite as visible.

I just took the time to go through this build thread for the first time.  I really enjoyed all of the updates.  You are doing some great work on this model.  You are in the home stretch.  I’m looking forward to seeing your next update.

Installed the rest of the braided fuel lines and installed the fuel tank permanently.   Realized that after finishing all of that the majority of it can not be seen once installed.  I've got a few more things to finish up and the front "bonnet" will be complete.

Thanks Jason!  I was kind of afraid I would lose most of the details once the body goes on.  At least I'll have the pictures to remind me what all went into it.

Other than some paint touch ups that will be done later the front fuel cell area is finally complete!  I finished it up by adding clear .8mm stretch cord for the fuel overflow lines and 1/16th inch Evergreen styrene rod for the fittings and tee fitting drilled out to accept the clear lines.  I think I made the tee fitting a little too large, it seems a little out of scale.  I also made the electrical block for the fuel pump out of Evergreen square tubing and the wire is Cat6 phone wire stripped and covered with shrink tubing.  Next will be the harness and installation of the seat.

With all that race equipment there's really no room for bags in the boot, is there? 😮 

Excellent work on this! The more you do the more 1:1 it looks.

I put the seat belts together today and I must say they are some of the easiest to assemble that I have used.   They are made up of 23 PE pieces and 11 pre-cut pieces of seat belt material.   As soon as I get the seat painted I can get the belts installed.   The frame of the seat seems to be a semi gloss black and the padding a dark grey.   I'm trying to mix something up that will be close to the pictures I have.   Sorry the pictures aren't real good, hopefully when I get final pictures of the assembled chassis outside they will be better.

Thank you guys for the kind words.  I'm currently trying to get the fire extinguisher distribution line made that runs along the bottom of the dash and along the drivers side of the to cage.  It has been a fight the whole way. I'm going to try and get some pictures tomorrow of the progress and the seat belts installed on the seat (not connected to the roll cage yet).

Installed the seat belts this weekend and started working on the fire system distribution line that provides fire extinguishing to the drivers cockpit.   The Tamiya seat belt material and PE hardware was some of the easiest I have ever worked with.   Unseen in the pictures are the eyelets that the lap belts click into on the sides of the cockpit.   Great detail!  The fire distribution line is made out of 3/64" Evergreen rod and the distribution holes were drilled with a #68 bit.  It took me four tries to bend the rod in the right shape with all the bends in the right spots.   Not totally happy with the final result but I think it is a cool detail.   I still need to make two straps to hold the line to the dash.  The line is held to the roll cage using MFH 1/12th scale zip ties.  They are extremely delicate and i broke 11 of them to get six on the roll cage!  Hopefully none of them break when I install the cage and hook up the fire line to the dash and the extinguisher hose.

To be honest with you I don't know what that half moon cut out is for.   There is one on the other side of the seat also and both of them have a rectangular notch in the seat frame right below them.

I hope you have better luck with those stupid MFH zip ties than I did. I had the same failure rate as you but managed to get the job completed. Over the course of two days, three of the installed zip ties broke just from me looking at them. I wound up going with 1/32 Chartpak tape to represent the ties.

Ok Jason I feel better knowing someone else suffered a huge failure rate!  What i ended up doing is spraying the roll cage and the ties with Tamiya semi gloss in hopes that it would keep the ties from breaking.   I has the same issue, yesterday i picked up the roll cage and one of the ties broke.  I didn't pick it up anywhere near a tie!  Very frustrating.
