  1. Actually, the writeup in the manual says, on the Mk 1 and 2, the annulus gear is integral with the rotating hub, and the non-rotating planet gear set is mounted on the hub carrier. On the Mk 3/4/5, the situation is reversed; the annulus gear is supported by the fixed hub carrier, and the planet gear set rotates with the hub. This reverses the direction of rotation. Sounds like quite a significant mod.

     

    The manual has some diagrams to show this but they are very poor quality.

    I wonder why they bothered to go to this trouble. It has to be related to the size of the wheels. I wonder did the gear size change in order to compensate for the larger wheels.

  2. Glad to help, Robin.

     

    An important update: I just noticed in the manual that the sketch above ONLY works for Mk 1 and 2 Ferrets. (Ours are all Mk 1's.) The design of the planetary gearset in the wheel hubs of Mk 1's and 2's reverses the tracta joint rotational direction so the wheels turn opposite to the tracta joint shafts. In other words, the tracta joint shaft between a bevel box and a wheel is turning the opposite way to the wheel.

     

    On the Mk 3 to Mk 5 Ferrets, the manual says the planetary gear arrangement in the hubs was redesigned so the wheels rotated in the same direction as the tracta joint shafts. The "ingenious" way of dealing with this was to change the F on the Forward/Reverse lever to R, and vice versa. So you pull the lever back to go forward.

     

    njjeeper, if you have a Mk 1 or 2, the sketch above is correct. If you have a Mk 3, 4, or 5, you need to reverse all the directions.

    Thats interesting, they must have put a second set of reduction gears in the hub, the same as is in the Saracen, Saladin etc. Probably to reduce the speed created by the larger size wheels.

  3. You are confusing the hell out of your self. I have built a few Ferrets now so I will try and part some knowledge your direction.

     

    First of all you cant rebuild the Bevel box "wrong". There are only two gears meshed together in the box. in order to get the output shaft to rotate the wrong direction you would have to place one of the gears on the opposed side to the other one. This in physically imposable to do due to the shape of the casting.

     

    If the box was stripped down and rebuilt, the worst he could have done is shimmed it incorrectly, this will cause extensive ware.

     

    I don't understand why anyone would go to the trouble of dissembling a box to such an extent. If you brake one NOS ones are still available. The only time I have needed to open one up was to re-shim the input gear, very easy to do.

     

    If the bevel boxes are fitted with the air breather facing up and the input shafts are all pointing at the gearbox then its fine, as far as rotation of shafts go anyway.

     

    I hope this reassures you a bit. Ross

  4. Thanks Jonathan.

    I am using a DC arc plant. I found I could turn it down and do 1.6 no prob but the 1mm wing was much harder. I am going to repair the wing I have first, so I know what it should look like and see how it turns out. If its poo I will make up new ones from 1.6. Thanks for your help mate.

  5. I have been working on the front right wing. I don't have the equipment to make compound curves or the money to pay someone else to make them so I have to try and repair what I have. I have never done welding this light before. I will see how it comes out and decide if they are good enough to use.

  6. What's the Manx registered motor that's in the background?

     

    I cant remember, but I know we were storing it for a friend of my dads. I will ask him next time I see him, if I remember.

     

    Just asked the old man, It was an Austin seven tourer.

  7. Hello, if the steering wheel renovation was done by the same company that did my Bedford QL steering wheel it will start to crack after a few years of use !

    Found a good second hand steering wheel for my QL and also for the Morris C4, these wheels are a bit ruff but will go on to the vehicles.

     

    I hope not :-(. It wasn't cheap.
