RE: Bentley plots first ever pre-war continuation car
Discussion
The above image had me slightly perturbed, as a result of which I showe it to an friend who is a cabinet maker and joiner.
He steered me to this:
“ While wood knots carry visual appeal, they adversely affect wood strength.
Wood strength in knots can be assessed in two ways: tensile strength and compressive strength. These measurements allow us to predict how much load (weight) wood can safely bear before collapsing. Tensile stress elongates or expands an object. Compressive stress shortens or compresses the material.
Since knots are defects that weaken lumber, this weakening effect is more serious when the lumber is subjected to forces perpendicular to the grain and/or tension than when under load along the grain and/or compression. Please note that the extent to which wood knots affect the strength of wood depends on their position, size, number, and condition.”
Whilst it would appear on the face of it that the cars may not be subject to the roads, they may be used in a competitive or semi-competitive way (thinking Goodwood FOS)
If so, I’d have thought that they would have gone for wood without knots just to ensure that everything is just so (and yes I’m sure Morgan et al have produced cars with plenty of knots, but then they don’t weight the same I guess?)
Just a question / thought, not wishing to start an argument with anyone btw!
Having lurked for more years than l care to rememeber, l couldnt resist the chace to comment regarding the appearance of the the
timber. As an Associate of the Institute of Wood Science, I would say that they are not knots {no puns intended} but what are known as Mudullary Rays. As this is a petrol head site I will not bore you with tree growth and make up, if it interests you WIKI has all the information.

True, but it's just a body frame, and only really has to support itself. All of the suspension loads will run through the separate chassis.

Had to dredge my memory backs to A Level Biology back in 1981, and even then had to look it up, knew xylem and phloem ran vertically within a plant or tree but couldn’t remember the medullary rays.
Still think they look like knots, and why not (pun intended!) as it would make sense but I also agree with another poster that mentioned it not being structural.
My only thought was if a customer is going to be paying through their back teeth they would surely want the most perfect finish, not (again!) that it would be seen much I’d guess.
I could just about stretch to a part used tin of Ronseal and a brush stuck in a jam jar that is stiffer than a stiff thing, so I doubt I’ll ever get near owning one 😜

I don`t have any qualifications but isn`t it spelt ' Medullary rays' ?timber.

Crayon might be stretching it.
Cave painting maybe... but what an awesome painting.
I’m privileged to have done a few precious miles in the donor for this project and it’s a memory that will last for ever.
They may not be road legal but as a mobile art object they are something to behold.
