Austin Ulster build
By: Ukrobotman Date: January 4, 2019, 4:54 pm
---------------------------------------------------------
This is my build. Started November2018. Loosely based on a 1927
Austin Ulster.
3”x 1” chassis then will be clad with plywood and fibreglass for
the curved parts then painted.

Hi Steve, that's the car I used as the inspiration for the
"Great Austin 7 build off" which I participated in. The photo is
after McLaren International re-restored it and took it to the
polar opposite of what it had been when Bruce owned it. I have a
lot of unpublished photos from the McLaren archives. It was
NEVER pristine. Getting the scuttle humps right will say whether
you achieved it. (Opinion only)

missed

I’m now working on the body. I’ve mocked up the basic frame in
6mm mdf. I’m now. Carving the curved section in foam ( expanded
polystyrene ) I build profiles in mdf then hot wire the foam to
get the basic shape, then carve the curves wth wire brush and
sandpaper. Next I’ll skin then make moulds in fibreglass

Nice work. Would you be happy to share any more details about
the how?
Is the back section made up of 3 sheets glued together? How do
you glue it? Do you simply hot wire a straight line between the
two profiles? How do you use the wire brush? ...so many
questions!

Hi Stefan, this is kind of what I do a lot of the time for my
business
Polystyrene... I buy blocks, 8’ x 4’ x 2’
I have a special hot wire transformer, special thin wire and a
pair of cables
I make profiles, place them either side of the block and with
someone to help me we cut one profile out
Then turn 90 degrees and cut the other profile
To be honest, you can’t do this in your garage. You need space,
a hot wire transformer and big blocks of foam
If I didn’t have this I’d do it the traditional way with
profiles in mdf like building a boat hull and fill gaps in with
foam or plaster
Hope that helps.
When we have a Builders day up here I’ll demonstrate for all
Steve

I do exactly the same without a hotwire. Handsaw does the rough
cuts just as well as long as you use foam with small bubbles. I
use another chunk of the foam I cut off to "sand" the shapes.
Surform or similar tool does a good shaping job, as does a bread
knife, or electric bread knife. It's very easy DIY. No expensive
gear needed. I did it for a living for some years.

Gel coat going onto the pattern for the back end ( or is that
liquid chocolate 😳)
Prior to layers of fibreglass
