1960 Grantura chassis

[puddle duck]

Hi I would be very gratful for some information regarding chassis tube sizes.

I have had my Grantura 7/B/151 for many years mostly in bits unfortunatly the chassis was not stored very well and now virtually needs to be rebuilt before I have nothing left to take dimensions from, Iam ok with the majority of tube sises but am not able to work out due to corrosion the diameter and thickness of the torsion bar tubes.

Any help with this would be much appreciated,

Keith

Hi ..Speaking here with Luckycarter...he will check the OD out when he gets home..but these tubes require reaming to size to allow the bronze adjuster to drop through to the centre (we have a drill tool to do that job) where you based?

Hi Keith,
Measured the torsion tubes on mine and taking in to account paint etc they appear to be 1 7/8" o/d and they are 16 gauge which makes the wall thickness 1/16" (1.6mm), hope this helps. From the ch/no i take it your car is a MK1, any pics/history etc Reg No ?, i have lots of period Grantura pics mainly racers, maybe yours is among them,
Cheers Rich (7/b/296)

Hi Adrian & Rich

Many thanks for your replies I live near Brigg, North Lincs not far from the Humber Bridge but travel about quite a bit so would be happy to bring bits.

The rear tubes prior to getting the car had been reinforced badly with scaffold tube that and missing bits together with moving house which got the car put aside and more or less forgot about (thirty or so years and several moves)until now which means it has become bit of a basket case. But in view of the numbers of mk1's it must be worth restoring if I can, in any case I need a project and my pride would be bolstered if it came out of garage in one piece.

I will see if I can dig out and convert some photo slides I have and take a photo of the chassis as it is now.

Thanks again Keith

Sounds like this is going to be a long haul. I have only ever seen 2 or 3 Turas and I think they are fantastic looking cars. You must rebuild her if you have the time and skills. With the prices of Granturas these days, at least you would recoup the cost of rebuilding her.
On the subject of chassis, does David Gerald build new chassis for the Grantura? I was that way a few years ago and they certainly had the jugs to build the chassis for one of the early models.
If you have a few pictures that would be great. You just cant beat a few dusty 'before restoration' shots!

Hi Keith,

when I had my chassis done, the torsion bar tubes at the rear had split, so I used slightly thicker tubes and had them manufactured as cold rolled seamless - I also used phosphor bronze to make the trailing arm bushes (inside the tubes).

Hope this is of use - I have lots of photos from the rebuild if you need to take a look - I only live over the river in Hull!

Good luck

In case it helps, the DG replacement chassis for my Vixen was definitely thicker wall than the [bent and rusty] original - I don't mind, it should be stronger...
