Our LRDG Chev

[T Creighton]

Hi Andrew,
The wheel bolts are 7/8" BSF 11 TPI. I have a die nut and a tap you could borrow if you are stuck. My address details are in the NZMVCC register or you could PM me on this forum.
I have been following your thread from the start. Congratulations on the progress.
It will be great to have another LRDG vehicle for parades.
Regards Terry.

Thanks Hanno and T Creighton,

We must have counted the threads wrongly We will have a closer look this morning.

When we checked the rims this morning we again counted 12 threads per inch, so I am still confused. But in the meantime we managed to borrow a special die tool that can be used on any thread and that worked well. Thanks again to all who responded.

We are now making our "bush bar" or "scrub bar" (I am not sure what the correct term is) to attach to the front bumper. Judging by wartime photos (see pic attached), the LRDG appear to have used the same type of bar used on all of the Blitz type of CMP trucks. Can anyone tell me what diameter the horizontal pipe or bar is? I assume one inch?

[Andrew H.]

Nobody responded to my query (above) about the bush bar or scrub bar. Maybe it was a silly question, but I still need to know the answer. Could someone please measure their original horizontal bar and tell me its diameter? Thanks in advance.
Andrew

Im working on making one of the brush bars. I will get the diameter and wall thickness for you tomorrow. I will also post some detail pictures of the parts.

Picture #1
The bar is 36" long, outside diameter 1-1/8", inside diameter 3/4" The ends each have a stopper on them. 1/4" thick, outdiameter 1-1/2", inside diameter 1-1/8" They are welded all the way around on the inside edge.

Pictures 2,3,4 and drawing
The metal is 3/8" thick, 2" wide flat stock. The drilled holes are all centered on the 2" width. They have a diameter of 7/16" The measurements for the bottom pictured brakcet were taken from the far right end of the bracket working left to each hole's centre. The top pictured bracket I only measured the first hole from the left end. You can then bolt them together to get the holes all lined up. The bolts that went through the bumper also had spacers to act as a stop for the bracket on the rear side of the bumper.
