R Cubed Posted May 16, 2012 Share Posted May 16, 2012 Hi all, can someone measure the diameter of their legs for a CCKW gun ring mount, the three which clamp to the cab, I need a pole for the front clamp by the windscreen but cant decide what the diameter should be ?

deadline Posted May 18, 2012 Share Posted May 18, 2012 I would assume a few mm less than the diameter of the hole? I only have pictures of the legs.. I've not see an MG mount on an open cab truck. If anyone does have pics... please post! Quote Link to comment Share on other sites More sharing options...

If anyone does have pics... please post! Try a search, there have been a number of pics on here. Big Ray's truck is fitted with a gun ring and there has been a photo of it within the last few days.

cosrec Posted May 19, 2012 Share Posted May 19, 2012 not getting to technical but guess it will be imperial size . so guess to the nearest 1/8 th of an inch and it should fit Quote Link to comment Share on other sites More sharing options...
R Cubed Posted May 19, 2012 Author Share Posted May 19, 2012 Yea, ok I guessed it would be imperial, however the front clamp by the windscreen has a 3/4 inch gap down between the bolt flanges so there is room for lots of play, dont want to over clamp it if its a bigger size than I thought !!!! Any idea's. Quote Link to comment Share on other sites More sharing options...
Adrian Scott Posted May 19, 2012 Share Posted May 19, 2012 Hi Richard , Ive just been out and measured the gun ring legs on my Ward lafrance and they measure 2 and a quarter inches , i then measured a spare set of legs in the workshop and they measured 60mm !!! my guess is 2 and a quarter inches but please wait and see what other people come back with , Cheers Adrian .

Adrian Barrell Posted May 19, 2012 Share Posted May 19, 2012 Repro legs are usually made from 2" nom. bore or 60.3 CHS which are both 2 3/8" o.d, so it is likely your second set are that. I made some once and I remember that the original size was a little unusual but I can't remember for the life of me just what they were!

Degsy Posted May 19, 2012 Share Posted May 19, 2012 Old scaffold pole could, perhaps be made to fit, at least would be cheap or even buckshee;) Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted May 19, 2012 Share Posted May 19, 2012 Scaffold poles are 1 1/2" NB, 48mm od so a bit small. Quote Link to comment Share on other sites More sharing options...
antar Posted May 19, 2012 Share Posted May 19, 2012 Just nipped outside with the tape measure as I remembered I have a set of cast leg tops lying around. The holes where the tubes fit are 2 1/4 inches. Quote Link to comment Share on other sites More sharing options...
Degsy Posted May 20, 2012 Share Posted May 20, 2012 Scaffold poles are 1 1/2" NB, 48mm od so a bit small. Must measure some poles I've got on the farm somewhere, I know they came off a building site years ago and I always thought they were 2" plus.
