Dear all,
I'm really disappointed because I want to be more active on HMEM, but not yet retired and have "only" 28hours in a day.
I start a very exciting model build in Germany by JT-modelle (Tobias & Klaus)
Don't hesitate to take a look on www.jt-modelle.com
Quality castings in Cast-iron, Aluminium, Zamac, folded steel profiles, internal-gear, etc...
Two stroke engine, differentials, reductor, clutch, gearbox, it's a very complete kit.
I wil also keep your attention about the "5 stars" "after-sales" service.

I start the kit with the machining of the wheels. at first, the flanges from bar-stock aluminium foil. After that, machining in steel the diabolo form bearing holder. Four time the same. Start the assembling of the spikes, rims, everything with copper rivets and rivets-gun.
The supplier for the rivets-gun and the rivets is www.ateliermb.com in Switzerland.
Regards
LeZap

Looking great so far. Thanks for sharing.
 
That looks like an outstanding model. The video clip on https://www.jt-modelle.com/ is very intriguing.

Is the kit sold by jt-modelle.com or somewhere else? I did not see any kit information on their website.

Please keep us posted with your progress.
 
The aluminium casting block is aways a problem, because there is no flat side
And you need to check to have, at mins, two faces flat and square at 90°
Boring is also a challenging job, because it's a long bore with vibration risks for the tool.
There is an idea of tooling made from 20mm silver steel and HSSCo cutting end.
I made also a jig of the opposite side to avoid the vibrations. The result is quiet good with an error of 0,05mm (0,002")
