Mercedes 300SL Gullwing 1/24 Tamiya with photoetched detail up set from Hobby Design

[Pouln]

Well done so far.

[CrazyCrank]

Afternoon, Gentlemen

 

First of all, this morning, I've realised that I made a mistake, while fabricating the arched front crossmember.

Il reality, it isn't symmetrical , the left part is very different, so, I've reworked it.

 

The wrong part:

 

 

The good one:

 

 

Then I've begun to add some framing on the left side, that serve to support the dashboard on the left.

 

It won't be possible to add the large tubes between these parts, because of the design of the Tamiya kit dashboard.

 

  

 

  

 

 

And with the firewall and the tub dry fitted:

 

 

  

 

It remains to do the same thing on the right side...

 

Stay tuned and thanks for watching

 

[Spiny]

Incredible work as usual, looks as though you're making an excellent kit even better. It must have taken a lot of work just to track down the differences between the spaceframe of the real thing and the kit, let alone fabricating the extra bits.

Evening chaps

 

When I'm busy, I doesn't laugh 🤪

 

So, I've went on my chassis frame enhancement.

 

I've chosen to go on the left side, instead of doing the right side of the dashboard stand .

 

I realized that before scratching the 2 following parts, the oil tank mounting brackets, I had to fix this oil tank, in order to place the brackets correctly.

 

So, I decided to fix the oil tank first.....

 

But, I wasn't happy with the bottom of the tank: the Tamiya part hadn't bottom, so...

 

- I glued à 0,5 mm thick styrene sheet plate over the bottom of the tank

- I cut off the excess with chisels

- Files and sanded it

 

And I got that:

 

  

 

 

Furthermore, I wasn't happy  with the bagging head of the Tamiya part. I decided consecutively to modify it:

 

- First: cut the ugly  plastic stuff .

- Second: Turn on the lathe a new bagging head using a 4 mm brass rod, reduced to 1.9 for the bagging head, and 2.2 for the cap

-Third: thread a 2 mm hole on the tank, tilting the drill bit in order to get a tilted hole

- Fourth: CA gel glueing the brass part on the plastic tank

 

And I got that:

 

  

 

 

 

Once fixed in trace on the frame:

 

  

 

Then it was possible to scratch the 2 muting brackets with 0.9  and  0.5mm bras rods, soldered together, and to fit them on the chassis, after an improbable number or trials an errors.

 

  

 

 

 

Now, I can switch to the right side of the frame and achieve it before the painting job.

 

Stay tuned if you like, and thanks for watching and criticizing

 

 

I was about to continue my work on the right side of the chassis, when I noticed that, on the left side, there was an important part of the car, that had been forgotten by Tamiya: the vaccuum cell:

 

This part, on the real car, is place just beside the oil tank, at the back.

 

After having analyzed some reference photos, I've scratched it with:

 

- a 4 mm brass grid, on the lathe

- a 0.9 mm brass rod

- a tiny plate of 0.4 mm brass sheet

- Soldering pasre

- 0.3 mm diameter welding rod and CA glue

 

And I got that:

 

  

 

   

 

Once achieved and glued on the frame:

 

  

 

  

 

Now I can switch to the right side of the frame and achieve it before the painting job.

 

Stay tuned if you like, and thanks for watching and criticizing

Can't see anything to criticise there mate...gorgeous work as always.

And now, before the right side achievement , some pics to the chassis as it is at the moment...

 

  

 

  

 

I'm pretty happy with this result

 

[Hamden]

 

Superb engineering as always with stunning attenion to detail

Evening guys

 

Chassis improvement achieved this evening, and ready for  primer coating 😉

 

  

 

  

 

Stay tuned for the next steps

 

[johnlambert]

Looking forward to the next instalment.

[CrazyCrank]

Don't be eager @johnlambert 

 

First coat of Alclad Grey Primer and Microfiller sprayed over the chassis, second one tomorrow afternoon when daylight will be better.

 

Magnified photos are merciless, pity, and some smooth sanding with Tamiya sponge 600, 1000, 2000 and 3000 grit is needed before the second coat .

 

However I'm already pretty happy with this first result:

 

  

 

  

 

  

 

Stay tuned if you like 🤪

Superb looking chassis, those pics: could be mistaken for a 1:1

I agree...What a beauty!

Congrats Thierry!

[CrazyCrank]

Thanks for you kind word, my friends, most appreciated

 

[harveyb258]

Ooooh, I do like a nice tube chassis. 

Nicely done, Thierry.

 

Cheers, H

Called "bird cage" isn't?

Right

 

[CrazyCrank]

Evening gentlemen

 

The bird cage has been cleaned and smooth sanded  before the second layer of Primer.

 

I chose to use an old Alclad Grey Primer that seemed useable and began to spray it on the chassis, but a bad aspect appeared quickly, so, I stopped the job, let it cure and dry completely.

And another careful sanding job had to be done.

At least, I could spray the same primer than for the first coat, and all is now OK.

 

But I can't progress tonight on this build because my little workbench has been invaded by strange planets (Mars and Mercury) creatures:

 

 

Have to wait until tomorrow to go on with the Mercerdes (and the Delahaye too)  🙄

So there is life on Mars andMercury after all. Here on BM we do not need astronomers to prove it....😎

[CrazyCrank]

Ooooooops guys ☹️
i just realize that I’ve forgotten to scratch the battery housing and some engine mountings before priming the chassis...

I’ll try to do that next week 🙄

[CrazyCrank]

No drama though...

these are accessory scratched 😉

 

I’ve highlighted them in red on the photograph below:

 

 

[alteregoni]

Wonderful stuff here! 👍

[CrazyCrank]

Good evening/night chaps

I went home after a shiny week-end in Ré island (near La Rochelle), and have found time to work a bit on this MB 300 SL

 

So I've modeled with Fusion 360 the battery housing, using the Mercedes Benz 300 SL Ref. blueprints to get the right shapes and dimension.

After a couple of hours, I've got a pretty accurate design:

 

Successively Side vue, Front vue, Top vue

 

    

 

And 3D vue:

 

 

It remains to 3D print it, make test fits, and if OK, or, after modifications, to glue it in place.

Then I'll model the battery with its terminals

 

I've also added on the tubular chassis the tube which retains the battery from its bottom side:

 

  

 

  

 

The work to represent the 4 left front tubes which are joined by a plate could be more difficult, and before to scratch this sub-assembly, the function of which isn't obvious for me, I think it's necessary to assemble the engine parts and to test fit the engine block on the frame, in order to determine whether the addition of this sub-assembly will be possible or not

 

So, stay tuned for the continuation of the adventures

This is looking great. I approve of your invaders of course!

Mind boggling tube work and attention to detail Thierry...stunning work.
