You are really lucky to have such a material at arrangement. I am jealous

Beautiful work, I can not wait to see the continuation of your excavator ^^.
And ... welcome to you on this forum, we are happy to be able to exchange our knowledge with yours which apparently are already very good ^^.

thanks guys 9127tony.. me too, I started this project in 2013
For now these are the latest developments, I have some advanced parts, but it is still early to show them, I prefer to wait to have them more defined, I currently have a lot of work and I can not spend much time on the excavator, it is a long term project, but I will post the progress (i hope soon)

best regards

Hi, too long time without news, sorry, i will try to put the thread to the day, with a few words and many photos
we started
this is the counterweight of the machine, this is only the model 3d printed to obtain the final part from casting
The first thing to decide is the material, in this case I have chosen to make the counterweight, lead, by weight it would be totally out of scale, but I want to give a certain touch of "forcefulness" to the machine, besides, to remove there is always time

next part, letters and details, at this time i thought to use 3d printed part, but sure i have troubles in cast, no way, plan B


the cast








I have to pause.. a little problem


a rebob (i don´t know if is the correct word, a superficial fail) i have to repair, first i have to prepare the surface and after use a epoxy putty to fill the fail and and a lot of sanding by hand...

... or not, better to use the machines




Now time for the details, i have use my diy mill and wire edm










the final look has to be similar like this



a pair of video

I have to catch my breath and I'll be back soon

thanks Granfauve, I still have a lot to teach

We continue, this time, the bucket, this is a pretty piece, made of steel sheets cut with laser












on the inside, it measures 185mm

ok, next phase
i will do the "tooth" and "tooth holder" with lost wax process, but using 3D printer technique (ussing a diy 3D printer), first time, to make the 3D print model (i use different types of resin)










now i use those part to make silicone models to obtain wax parts




(how easy and fast seen like this jeje)






the pieces welded by brazing







and almost finished (yet not, I have to add minor details)




regards

Excusez moi je ne parle pas l'anglais............mais les photos parlent d'elles même et c'est un boulot magnifique
SUPER SUPER SUPERBE je voudrais bien savoir en faire ne serait ce que le 10 iéme
Bravo et bonne continuation

[TESSEN]

Thanks guys
clau, (or anyone who want to say anything) don´t worry about the language, english, french, spanish does not matter, the english it's not my mother tongue either and i have to strive to express myself, I appreciate the effort (and thanks to the forum for letting me write in english)

another piece, the arm
are made of steel ribs cut with laser and welded together with MIG




the previous piece need on both sides spacers, made of brass and using sand casting technique, those part are glued with epoxy to the main body, but it´s not important, once time in place, can´t move






and after machining





now the part that hold the bucket hydraulic piston (made of brass) in the arm








and all the pieces that form the arm


this part is a rock protector in the lower side of the arm




and the final piece (almost)
