Hi Guys Been looking around and found two examples of these gearboxes one on a French site and one on a Dutch site.
Anyone know who makes them and the cost ?

Hi pete,

If you do a search on "Marcel Rientjes" or "MR gearbox" or "MR Getriebe" you will come up with various hits on various sites for his gearboxes.

The steel gears are from Conrad, who are the nearest German/pan-European equivalent to Maplin. Unfortunately their range in the UK is limited. Every few years when I visit Germany (last time Munich Summer 2009 - hic!) I buy their catalogues. They do several. Their "Modellbau" one covers a wider range of gears than they have on the uk website:

It might be that if you trawl their German website you can find the numbers of the correct gears (module 0.5 or 0.6, not sure!) and still enter them on a UK web order...

I'm sure it would be possible to make your own gearbox cases with a hacksaw and a file and some mechanical nouse. Unfortunately I never did any metalwork at school so I flounder in this area! I'm also notoriously bad at drilling in the correct position in a straight line!

Flanged bearings, shafts etc are easily available via places like Technobots:

Good luck!

PS Looks like Technobots have increased their range of gears and have something similar to the Conrad ones now...

At first sight those look great, but I don't like the price!

Another couple of comments I would make - firstly I bet they are very noisy because the gears are all steel. Secondly, I'm not too keen on all the gears being secured to the shafts with grub screws. It only needs one to come loose and your tank will go round in circles.

Nicely made frames and I do like the liberal use of proper bearings. But there seem to be an awful lot of plain steel washers in there used as spacers. But no washers used under the nuts on the frame pillars?

Nice kit, but I think for the price they could be better engineered.
