to make this the ultimate gift to your son - once you've built it in secret - take it apart, put it all in bags and sort it like lego do put it in a box and get some instructions made for your body as the instructions already exist for the 9398 chassis... ..i.e. dont just give it to him made - my boys were following lego instructions properly since age 3 - its all part of the experience.

'Reverse' Bricklinking
Rockbrick replied to DrJB's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
actually there seems to be more 8466 on ebay than ever at the moment and probably cheaper than buying the parts (used for used equivalent, new parts is a different story) -
I would use the narrower rigid tubing (same diameter as the T junction pieces) this is thinner than the flex axles but if you wanted it thicker you could insert short pieces into the end of larger diameter pneumatic hoses problem is these are too soft and only available in Blue and Black and Grey if you want to go down the lego purist route third party tubing must be available stiffer and in all colours.... and thicknesses -

Efferman's Custom Parts
Rockbrick replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I remember having a Kyosho RC car at the same time as getting into technic and I was always amazed at how thin the differential was on that model using 4 or 3 lego 8 tooth standar gears and 2 standard 24 tooth bevelled gears a custom driving ring would then enable the whole diff to be 3 studs wide.... -

Gears, most wanted
Rockbrick replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Surely this could be done with a combination of a turntable and the 16tooth lego clutch gear with the teeth so it can link up to and old lift arm (or put a pin through a 24 tooth on any beam) -
[MOC] A.L.T. 6x6 mkI
Rockbrick replied to Doc_Brown's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
