These parts are those that articulate the bucket with the arm,
This piece is made of brass, joins the piston with the bucket, some photos of some parts of the machining







and these 2 parts make the bucket pivot on the arm, they are made of steel (I do not like to work with this engine ... it is a factory to produce pins)









and this a presentation of how it´s works

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

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!

In all cases congratulations for your nice job!

Hi Spirit

buff.. is hard to explain me in english (more), i spent more than a year to get to understand the technique, in essence, consist in introduce a calcinable piece into a container cylinder, and fill the gap with refractory plaster, when the plaster is dry, we burn the piece and with the help of vacuum we fill the hollow with metal molten
better, i leave you a video, in this video explain well the technique
