I'm cheating! Frazer Nash (I think)
« on: 22 June 2019, 08:30:31 am »
As there are 2 weeks till Stretton as of today, and work got in the way of getting the Napier done, I have acquired the basis of a car which was constructed by one of the early people who got in, and out of cyclekarts in the UK.
Graham Hill allowed me to take this project of reconstruction over, so I have a lot less to do.
I have now to make a body and front end, although there is a vague chance that I will use what I have for the short term as the future has the front end getting an entirely new format, going to 1/4 elliptics and a straight axle.
I  guess I may as well do the body I'm thinking of, even if the front suspension isn't quite what I envisage for the future..

After a fabulous day at Bicester Super Scramble, the decision is made. This thing will be a Bugatti (as Fraser started) but different in that it will be  a Brescia, vague chance it will make Stretton. (I'm now quadruple booked for that day!)

I had to look to see what a Brescia looked like. No compound curves .....a good thing?!
What do you use to bend the alloy?
I have acquired some 1.6mm thick ally, but has been bent, so have panels 1m x 0.45m . 4 of them. The bonnet could be made in two halves, hinged or fixed.

When I can I bend alloy round whatever I can. This came with a bend, which I then"unbent" and re-did round the power pole outside my house. Several trips back and forth till it matched the radiator bulkhead shape and at the other end the dashboard panel.
To be honest compounds are not too bad if they are not excessive, the shrinker is a big help.
I also use my shrinker/stretcher, and bash bits over a shot bag.
I also fold between two bits of angle iron clamped to the bench for some things, then form them with the shrinker into curved bits for frames.
I remembered something I was shown years back, and now do a bit of wired edges where needed.
The grade of alloy makes a huge difference as to how easy it is. Learning to anneal alloy this year has been a game changer for me.
1.6 is hard work, unless it's a soft variety. The full size car has that and forming the body for that has needed some muscle at times!

Fail for Stretton July
« Reply #5 on: 06 July 2019, 07:41:58 am »
I have got close, but no bananas.
Has anyone found the carton of enthusiasm I left somewhere and can't find? Perhaps I chucked it out in a garage clean up.
It's a case of trying to do too many things again, and achieving none of them. (3 project cars as well as this thing)
I finally got the front spindles/stub axles back yesterday, now machined so that I can put bearings in the wheels. I need to look in the bearing container to see if I have any.
Rear axle spacers were also done. they will hopefully partially sort out the mismatch between the hubs (1") and the axle (25 mm). They go on the outer end to support the wheel, either it will need new hubs or perhaps another sneaky fix/bodge on the inboard side which will be only temporary.
I completely stuffed up the dashboard bulkhead/scuttle support, and now I have none of the free plywood to do another.
The front part of the body is ready to be fastened down. I'm using the top which Fraser made totally reshaped, and the sides are Dibond or whatever local trade name. The material is thin alloy skins over a form of plastic core used in the sign writing industry and more importantly free. It's an absolute **** to shape the slight compound where it meets the radiator shell.
The rear, engine cover etc hasn't been started, reality I haven't even come up with a way in my mind as to how I think it could be done, or even what it should look like, there are varieties of Brescia back ends, some more shielding of engine heat than others. Of course the one I like best is the one that shields the most, ie the bolster tank version.
Anyway, this is what it looks like 7am today.

In case folks don't know, here is a lovely period pic of a Brescia.

I think the carton of enthusiasm will be found at Streeton tomorrow.
We have all hit that, 'I don't know how to do', 'I can't see a way to do it', 'hell not certain I want to do this anymore'
moments, usually while nursing a sore thumb, or dripping blood! Or my personal fav,
the part you have just spent hours and hours fettling, that thing you just made falls to pieces or you just trim one final bit off...too many.


Re the engine cover, could you go with creating the silhouette of the shape from the side view, but leaves the engine plenty of ventilation?
Just a thought.

Engine cover idea isn't a bad one, the a dummy top cover when on display, or events where they need to look correct. I like that. I have seen other Brescia photos with a tail similar to what Kim has, and I know hot to do that. Perhaps one of each!

I have spent the afternoon mainly on the Brescia, apart from making some jigs/fixtures to weld the front spring horns for the Napier.
I now have front spindles that carry 17 mm bearings, a totally rebuilt front axle and odd other bits.
I decided to revise the steering column, as I didn't like the solid steering shaft and iron housing self aligning bearings. I now have a tube shaft and the bearings are graphite impregnated UHMWPE. The saving in this part alone has trimmed 3.7 kg from the car. It's also a whole lot cheaper for a new build, and having used the system extensively in my other cars I know it's more than adequate.
The side panels are all done, I have used what the Americans call Dibond. 2 skins of alloy sheet over a plastic centre commonly used in the sign industry. It's not light, but is self supporting, so framing is saved. (It was free too :) )
I have now decided to lower the floor, as it was effectively on top of the frame rails (300 mm from the ground) It will now go under the frame, at least in the seat area and as far forward as the scuttle. taking it out was the last task before coming in.
So, current position is that as soon as the front axle is welded it's drivable. Sept 2nd is now doable.

Nothing special Graham, it just had to match the stub axles, whatever they are. No science this time, as I'm just making a runner. I'll measure them for reference.

Hi Rhys,
