Just bear in mind you can draw exhaust fumes in through the
tailgate, keep the dash vents open and open the rear door
windows slightly to maintain a through flow. You probably
already realize that, but better to mention it than not.

Re: Bugatti Type 37 Build - steering wheel mini build
By: M.Z.Nahajski Date: April 1, 2019, 12:27 pm

Hi all,
For Dad and my Bugatti build I have been put in charge of the
steering wheel (which will replace the current..... interesting?
wheel). it will be made of 4mm sheet aluminium and wood. To
start with I created a cardboard mockup of the wheel to work out
my measurements and then transferred that to the sheet of
aluminium with a compass and scribe. Then I cut the outer edge
using a jigsaw leaving about a millimetre to file down when
finished. Anyone else building an aluminium wheel learn from my
mistakes and use cutting lubricant/coolant otherwise the metal
melts extremely quickly and ruins your blades. I have also cut
out the parts between the spokes of the steering wheel but am
trying to work out a faster way of filing down to the desired
size without the risk of over cutting with a saw and ruining all
the effort put in so far. If anyone has any suggestions for how
I could do this I would appreciate it. Also any ideas with
cutting, attaching and shaping the wood would be appreciated
greatly. :)

Re: Bugatti Type 37 Build - video analysis

The meet up in Coventry was a great opportunity to drive the CK
a bit. Basically it all worked but it was really interesting
to watch the video of it turning in slow motion because I could
see how much movement there is in the front wheels. My steering
box has developed lots of play and the king pin arrangement has
too much slack in it.
The key thing is that I'm confident the brake works enough and
will improve when I bleed it some more. Next step is to strip
down the CK, weld the tacked on brake bracket and then clean and
paint the chassis. Then we'll reassemble the whole thing and
start on the bodywork.
I need to come up with a solution to the king pin play, and also
dismantle my steering box to see if I figure where the steering
play has come from.

Yes the play can be sorted , the tube that the bolt goes in
needs to be drilled out of a piece of round bar in a lathe
rather than just a piece of tubing that’s close in size

Bit confused where you might have King pin play.
If you used a Gemeni axle, did you use their King Pin Spacer (&
top hats)

Hi Rich. I think you are correct, there should be no reason for
king-pin play using the correct components. I am in touch with
Gemini and am visiting with them to confirm this. Cheers

If you think the play is in the bolt, use a proper precision
10mm shoulder/M8 thread Shoulder Bolt (Shoulder Screw).
They would measure 10mm, unlike a common bolt.

Thanks for the ideas Rich. I'll report back when I've figured
out what's happening.
In the meantime, I've stripped the Bugatti right back and
painted the chassis with Hammerite Smooth. It's just as well
most of it will not be visible because its anything but "smooth"
- I used a brush. Is there a trick to getting just the right
amount on so it covers but doesn't sag?

I've never had much joy with Hammerite, for exactly the same
reasons. I tend to use Blackfriars these days, does the job, and
cheaper.

Hammerite....In the past, I’ve had some “luck” with both smooth
& the other type, using cheap oven cleaning/washing up sponges
(the sponge side), and dab it on! The smooth has dried smooth!
I Can only suggest try it on a test/practice piece and see if
the technique works for you?
Cheers Rich
