Pelle Hydraulique liebherr 984R 1:14
Hi,in the first place and after the presentation of myself in the correct section, sorry to write in english, if anyone want to write can do it in french, ok, the important part, the pictures
in those post i'll show the works of years working, is tired but it´s funny
i have not finish the 3D model yet but i want to machining something! ok, i´ll post a lot of photo and video,as note, and all my major machines are DIY
ok, here we go!
the first piece is a link of the chain
i have to machining 196 links, a preview model
a video of the machining (right link)

and the left link
[bbvideo=853,480]https://youtu.be/P0JbwqnjaF8[/bbvideo]
the traction wheel:
i use a cycloid gear inside the wheel cube with a relation on 1:100 and i turn this shaft using a timing pulley with a 1:6 relation --> final relation 1:600
sectional cut

[bbvideo=560,315]https://youtu.be/jrk4c-XzaZA[/bbvideo]
ok, this is the current status , i need to make the pads for the chain, at the first place i thought to machining it, but i have to rotate them in the mill many times, too boring, i had to learn another technique, lost wax casting
the first cast (bronze)
regards

Re: Pelle Hydraulique liebherr 984R 1:14
thanks guys!
Well, these are the most important pieces, now it make a dotted and drill (which has no mystery), one thing that if it could be funny / curious, are the nuts with hex screws that hold the pads to the chain, finally i did it with my cnc router, the pieces were made in brass, nuts are threaded to M2 and measure 3x3mm, totaling 405 nuts, machined with a 1.5mm drill (the champion of end mills)
a little video of the machining
[bbvideo=853,480]https://youtu.be/NHkC2UHnynI[/bbvideo]
and finally .. I could assemble the track
more photos, this is the time of the hubcaps for the traction wheel, made of aluminum
the master piece is made in 2 pieces, one milling and the other are made using laser engraving
after that, both are join
the mold and the wax copies
the result of the casting
salu2!

thanks for comments
more advanced, the lower structure, all stainless steel 3 mm and 1.5mm
the following photos correspond to the lost wax casting of pieces for support and guides rollers on tracks
and a pair of test of my future valves (for the moment, prototype)
