  1. CVR(T) Brakes are much better than you might think. I can't see many 7.5 tonne trucks or HGVs stopping like this...

     

     

     

    Incidently it's also possible to drive around in one all day, through traffic lights, roundabouts etc etc and not need to use the brakes. The tracks, engine and gearbox are very effective at slowing it down when needed.

  2. safariswing's link to the 'Hughes Guides' starts off:-

     

    "Brakes

    Braking systems of certain vehicles FIRST USED ON OR AFTER 1st April 1983. . "

     

    Surely all 430 series vehicles were first used before that.

    When were the first CVR(T)s around? 197?

     

    Just thought I'd point that out.

     

    Chas.

     

    British CVRTs were built between 1972 and 1982.

  3. So when did the requirement for a secondary braking system get introducted to the C&U regulations, and what type of vehicles does it apply to? Obviously a split system as quoted by Mike is not possible on a tracked vehicle, so how do the other tracked vehicles (such as mini diggers etc) which are road legal get past this?

  4. Hello mate

     

    You got any plans to do any CVRT's then ? I know AFV Club do the 1/35 Scimitar and Scorp, as well as AA doing the variants in 1/35 and the Scimitar in 1/16, but would be good to have some larger scale variants, esp with the later style headlights (the AA ones all come with the sealed unti jobbies)...

     

    Happy to help with reference pics if it gets mea discount..!

     

    Cheers

     

    Tim,

     

    There are conversion kits around to turn a Scorp into a Sabre, and also to turn early vehicles into later ones.

  5. you are correct about the cvrt tracks, the rubber blocks are moulded in and if they are indeed worn right down, the entire track will need replacing for road use. Note the pads have a tapered profile to them, thats to say the leading edge is flatter than the trailing edge. If you can find replacement track, expect to pay £1500 to £4000 depending on how worn

    regards mick

     

    £4000!!!!!!! If anyone needs good take off track, send me a PM and I'll pass on some details. It wont be anywhere near this expensive.

  6. This is amazing news for all UK Ferret owners!!

     

    If these tyres really are suitable, then they're the answer to all of our prayers. There has been much debate on this forum and elsewhere about finding suitable tyres for our Ferrets. These tyres look to be the first with the same (or very similar) tread pattern to the original fit Dunlops.

     

    Fingers crossed!!

     

    Peter,

     

    This is not amazing news...! These are 900x16, but they are the same pattern as fitted to Dodges, 101 etc and so not too hard to find. They are just Bar Grips, not Trakgrips which everyone wants.

  7. Tony,

     

    The composition of air is as follows:

     

    Nitrogen N2 78.084%

    Oxygen O2 20.947%

    Argon Ar 0.934%

    Carbon Dioxide CO2 0.033%

    Neon Ne 18.2 parts per million

    Helium He 5.2 parts per million

    Krypton Kr 1.1 parts per million

    Sulfur dioxide SO2 1.0 parts per million

    Methane CH4 2.0 parts per million

    Hydrogen H2 0.5 parts per million

    Nitrous Oxide N2O 0.5 parts per million

    Xenon Xe 0.09 parts per million

    Ozone O3 0.07 parts per million

    Nitrogen dioxide NO2 0.02 parts per million

    Iodine I2 0.01 parts per million

    Carbon monoxide CO trace

    Ammonia NH3 trace

     

    Therefore when you inflate a tyre with air, you are inflating it with 78% Nitrogen. Why would there be a problem with mixing Nitrogen and compressed air?! :nut:

  8. Iain,

     

    There was a story behind the missing dash, but it's fair to say you shouldn't bid on things in a tender sale based on the website photo alone! I got that info for him as I was interested to find out the history of it... Merlin report was done on the reg no. on the data plate.

  9. CRVT hull detail showing damage near final drive mounting.

    It's common practice for the front towing eyes to be removed from scrap hulls, they go back into stores as spares as far as I know. This looks like someone tried to remove them using a plasma cutter. All the ones I've seen have been cut off using a grinder.
