The 7 style chassis are a good starting point. If you look at the shape of a typical 7 with swept back front wings you will see that the Testarossa has some similarities. The seating position relative to the rear wheels is also similar as is the long nose forward of the cockpit. When the outer panels of a 7 are removed you are left with a neat, light weight space frame. Even down to the suspension, the Testarossa was a live axle at the rear with double wishbones at the front, same as the Westfields etc. Wheel base and track are also very similar and as I said before, I wouldn't want to modify the bodywork to suit a chassis. If a 7 chassis is that close I shouldn't have to modify that either apart from adding mounting points for the body.

I agree ...7 style will work if my previous mockups on a locost are anything to go by ....

Having built three "Sevens" in the past, look to Jim McSorley's plans on the locost usa website. Several variations in length and width possible. All of Jim's space frames have undergone a finite analysis too. Much better than the "book" chassis.

I've managed to strip the remaining paint over the holiday and sort out the dents at the front of the nose cone. I put in a couple of hours today lining up the front end panels and checking for fit and making little adjustments as required.
I'll get some ali sheet and steel tube this week in readiness to rebuild the scuttle panel. I should be in a position then to weld it all together.
I think I'm happy with the 7 style donor now, it seems to be the most logical and straight forward way to getting on the road. I just need to confirm the wheel base of the 250 before I start looking.

My comment was based on my driving experiences of a 7 ok for short blasts but quite focused and tail happy

I've owned 2 Westfields and several of the early monocoque Robin Hood 7's all with various engines from a 1600 Ford crossflow to a tuned 3.9 Rover V8. I also had a Ginetta 27 with a Rover V8, with an Escort live axle.
You are right about the characteristics of the 7 but the bigger engines with matched diff ratio make them far more drivable.
Remember the 250 TR was a small car designed for the track first and foremost all be it with a big engine. The original TR must have been a handful with the V12 engine and skinny tyres.

Guy up the road from me has a tiger(?) 7 ...with 2 Kawasaki engines in ....sounds like an old f1 car

Well you know 7's better than me that's for sure .... when I drove the 7's I was much younger and er heavier footed ha ha .....get my kicks on motorbikes these days as have no space for a fun car just yet.

I've got the outer wings tacked onto the nose. I'll offer up the inner wings over the weekend and tack them on too. I need to make up a frame to support the whole lot whilst I make the scuttle and bonnet . Photos to follow!

I have Coys auction house near me and today they have a tr in at the moment
It’s a very narrow car , I was quite surprised

A lot of the Maserati's , Aston's and Ferrari's etc are quite narrow..it's the replica's that tend to be wide as they use more modern axles , jag stuff etc.
I personally think many of the jag based cars actually look too wide ...

Ferrari 250TR Pontoon:
Wheelbase: 96.2 inches
Front track: 51.5 inches
Rear track: 51.2 inches

C-4 Corvette:
Wheelbase 96.2 inches
Front track: 59.6 inches
Rear track: 60.4 inches

We did a 250TR body and fabricated the wheelbase to the correct dimension, but had to widen the body proportionately to fit the C-4 track. Overall result looks good after a few "tweaks" around the wheel arches and tail lights.
Done as an R&D project, one proto has been built. The big Healey shown was also a "from scratch" project.

No thoughts on the cobra chassis build I posted?

Very nice indeed. Where'd you get the rear lights?

M,

I posted a link to the build thread for this fiberglass TR on the previous page, it is not mine. I am building a 275gtb on a volvo p1800. But if you click that link you can see how the TR builder made molds and cast the rear lenses himself.

Here's the link again for you

Any idea which page for the making of the rear lights? - I've trawled through most of the pages without success :sorry:

Along with the body there were several boxes and included were the original rear lights and lots of other spares. I'm not sure if they are common to anything else but they look authentic and the same as other TR's on google.

Many thanks...... Don't know how I didn't find it :doh:

Lucky - This clip popped up on my YouTube recommendations list and I thought of you.

Since then, I watched a few of these Chris Runge metal shaping videos.

It is amazing what someone with the right skills and tools can achieve. :cool:

Good luck, Paul. :)

Hi Towed
The pontoon 250TR rear lights were also used on the Lancia Aurelia B24.

There are a few sets for sale
