MK I carrier seats

[RichardT10829]

Does anyone have any images or measurements of the seat base for the rear seat ? It appears to be two cushions strapped together on a board,looking at the pics above supplied by Michael.

Richard, I havernt seen any measurements but I think there might be another picture of this seat set up in Nigel's vol 3 box of drawings, I am going to make two and thought is would be easy to gauge the dimensions from the carrier when you have the two rails in place it sits on and from an original cusion. But if anyone has an original ?, I know Jordan made one and it's in his carrier thread. Also the famous looking down photo might give an overview.

I noticed notches in the angle iron on the hull wall and presumed there are batons on te base of the seat board to stop it sliding out. Just

Hello Gents,

I want to make up the front and rear seat backrest for my Mk1, can anyone confirm the thickness of the radio operators wooden board and the cushions for both front and rear backrests?

I read this from Michael R earlier in the post but I’m not sure if it’s the backboard or the cushion that he’s referring to?

“When you also compare the size of the backrest for the rear compartment passenger with the backrest used by the driver and gunner, it must have been miserable in the back. The rear backrest is "deeper" in that it measures 1-1/4 inch sides vs the seat backs at 3/4 inch. Beats ground pounding?”

Cheers

On the backrests for driver and gunner, the corner depth is sewn in at 3/4”, but in practice when modern padding is installed the depth is greater towards the centre. Show or Go? I enjoy more backrest padding than found in the factory pads.

The rear compartment backrest cover has 1-1/4” corners sewn in.

The cover mounts on a plywood board, the board being retained on a metal plate using six NO. 8 woodscrews. The woodscrews are countersunk head, 1/2” long.

How thick do you want to make the mounting board? I use 9mm exterior grade plywood. It may be prudent to move up one size for a thicker board. Why? Because you are also mounting the male posts for the Lift-the-Dot fasteners, which are available as threaded post or screw. With a slightly thicker mounting hoard you will not be trimming the length of the screw type posts and they are less likely to be unintentionally pulled out.

That’s great, thank you R. That will give me enough to get some seat backs made. Got a load of ply cut and delivered to make the rear seat (thanks to Jordan’s post on his efforts), and seat backs etc. I’ll go thick for the rear seat back then to give enough depth for the screw in fasteners. I think I’ve gone 3/4”, as it looks like deep in the photos. It can’t be very comfortable for the passenger as the seat back is so far back from the seat cushion, unless they were expecting the radio operator to sit with his small pack on?

I’ll post something when I’ve finished my attempt.
