Re: CAT330D-L full hydraulic
Amazing!

Re: CAT330D-L full hydraulic
Great Clean Super Build......I will follow this job for sure. Where on the earth are you located ?
|
Re: CAT330D-L full hydraulic
WOW! Are you a professional CNC operator? Or just have one for personal projects?
Also who makes those hydraulic fittings? |
Re: CAT330D-L full hydraulic
Thanks a lot to everyone...
@Bo Wallen: i'm from Florence. @avel: i have been a manual/CNC machinist (mill and lathe etc.) for several years and begin to work with a lathe for hobby when i was 13 thanks to my father's mini lathe. But the work you see in photos is made by my personal manual lathe and mill (more heavy machines). The hydraulic fittings are made by SMC corporation in Japan. They sell all over the world and in the USA is more simple to find and buy it than in Europe. In Italy instead is a big problem... like for everything! Price is crazy! You can buy it from www.smcpneumatics.com or even on Amazon. Search for "smc miniature fittings M series". A few minutes and i'll send other photos... See you soon! |

OK thanks, and keep the pictures coming.

Re: CAT330D-L full hydraulic
Impressive!
How does the wheel motor work? Kerst |
Re: CAT330D-L full hydraulic
Yes I'm interested it that too, next time you have the wheel apart so us some pics of the way the hydraulics work. Very impressive build so far!
|
Re: CAT330D-L full hydraulic
very impressive build
|
Re: CAT330D-L full hydraulic
very nice work
|
Re: CAT330D-L full hydraulic
Great job:)
I'm also very interested of how you made the hydraulic motor, more details and video please. |
Re: CAT330D-L full hydraulic
Hi everyone, thanks a lot.
The motor is of the orbital type and it has 7.8 cubic centimeters of capacity. This is the first attempt to build it and the torque is too low even if in general it works well. I have now to receive the special profiled rotor-stator coupling from an external laboratory that work with CNC mill and reassemble the motor for the tests. Then i make a video.... |
Re: CAT330D-L full hydraulic
Thanks thuangs.

Re: CAT330D-L full hydraulic
Beautiful!
|
Re: CAT330D-L full hydraulic
Very nice machine work.
You are displaying great patience and bravery for making the hydraulic rotary manifold and making hydraulic motors for the drives. |
Re: CAT330D-L full hydraulic
gorgeous! trully a work of art!
|
Re: CAT330D-L full hydraulic
Nice work mate
|
Re: CAT330D-L full hydraulic
Thanks everybody!;)
@SmallHaul: Yes, the patience is a "must" for this kind of works on manual machine. The hydraulic motors has needed a lot of study too. Hope with the new CNC components it works well and has a lot of torque!:) Now some other photos of the machine. The arm painted with epoxy primer.... http://i.imgur.com/K8p2kzB.jpg http://i.imgur.com/mjKACFD.jpg http://i.imgur.com/M9Uje6j.jpg http://i.imgur.com/Bzb2YLp.jpg http://i.imgur.com/guvRQXO.jpg http://i.imgur.com/EcOCYaS.jpg Is made by aluminium sheets of 3 and 1,5 millimeters brazed together, so is box-shaped. |
Re: CAT330D-L full hydraulic
WOW this is superb! will be watching this one for sure. What scale is it in? or did I miss that bit?
Stu |
Re: CAT330D-L full hydraulic
Wow! Beautiful machining. Hydraulic track drive motors too. Very cool. Everything looks great so far. This will be a nice build to keep an eye on.

Re: CAT330D-L full hydraulic
Thanks Espeefan and Stuart.:)
@Stuart: it is in 1:14,5 scale. Here some photos of the chain rollers in stainless steel... http://i.imgur.com/lfh3JAl.jpg http://i.imgur.com/sArOIRW.jpg http://i.imgur.com/ybtra7B.jpg |
Re: CAT330D-L full hydraulic
Hi everyone, now i got the chain links just molded.
I put some of them under the model to see how is the first impression... http://i.imgur.com/zgoELY8.jpg http://i.imgur.com/yMpXBlO.jpg http://i.imgur.com/2xj3cPk.jpg http://i.imgur.com/GsAKFsK.jpg http://i.imgur.com/hcYAbkC.jpg http://i.imgur.com/uS7YRef.jpg http://i.imgur.com/823AbCv.jpg http://i.imgur.com/HLCPl0q.jpg I have to drill the holes, to turn the pins and the rollers and to assemble all the parts with e-clips. Another patience work.... |
Re: CAT330D-L full hydraulic
Exceptional workmanship indeed. Keep the photos coming! :)

Re: CAT330D-L full hydraulic
Thanks a lot to everybody, i'm happy that you enjoy the model.
In the next photos the chain completed, only one side. http://i.imgur.com/pFPERPL.jpg http://i.imgur.com/iDydLSq.jpg http://i.imgur.com/Cbv5edb.jpg http://i.imgur.com/cFlZSIS.jpg http://i.imgur.com/kQBXV6Z.jpg http://i.imgur.com/n78v36K.jpg http://i.imgur.com/BFqPnfp.jpg See you soon... |
Re: CAT330D-L full hydraulic
Wow! Nice tracks!
|
Re: CAT330D-L full hydraulic
This is looking so great! Did you cast the track pads yourself or????
Reg |
Re: CAT330D-L full hydraulic
Hello everyone,
@ Rcp57: I have designed the scaled model of the pads on 3D CAD, built the model piece on my milling machine and find a factory that made the copy of the model by molding. @Thuangs: The real machine has the options between 700mm, 800mm, and 850mm. This is the 800mm and in 1:14,5 scale is around 54,5mm (half millimeters lost due to the molding retirement). The inside Groove of the links is made for a wheel of 6mm and so is 6,5mm. Pins diameter is 3mm. My greets, Enrico |
Re: CAT330D-L full hydraulic
Hi Erik,
Really nice work, I like the precision of your CNC parts. The hydraulics looking good as well. Do you have a drawing/sketch of the hydraulic motor? |
Re: CAT330D-L full hydraulic
Thanks Ramon, but nothing that you have seen in the photos is made by CNC. Is made by manual lathe and mill. The part made by CNC is only the coupling of rotor/stator that i am waiting for complete and test the hydraulic motor. This coupling has a complex profile that can not be built by manual mill and the profile i have used for the first construction, only to test the overall working, is approximated and manual milled.
The motor is of the orbital type, has a 7.8 cubic centimeters of displacement, the distributor valve is of the disk type and the motor has no drain. For now i still have to definitive test it and prefer to not publicize the particulated drawings, i'm sorry. |
Re: CAT330D-L full hydraulic
Very clean build, if I were you I would make holes in the track pads where the dirt can escape from the idler and sprocket, if dirt packs up it can make the tracks skip or slip off, just a heads up! :)
|
Re: CAT330D-L full hydraulic
Thanks for your intervention Azonic, in effect the problem that you analize is well known. The reason for the decision to don't make that holes is mainly structural: the shoes are made to be as strong as possible and the holes in that position makes the middle section a little too thin. This is the same reason why i have choosen to don't make the holes that pass through the flank of the chain. Instead i have changed a little the design of the chain links in another zone to minimize the problem that you notice: if you carefully watch the point in which one shoe is coupling and slide with the following one (in the bend the chain makes around a wheel) you can see that there is an opening that (i hope) helps the dirt to not stuck in. In the past set of photos this detail is not so simply to observe but in the next you will clearly see it. Other further solution to the problem could be the lowering of the profile of the teeth on the sprocket.
Finally ther is a thing to say about this problem: the typical weight of this reproduction models is so low to amplificate a lot some limits in the functionality of the chain-shoes, so it seems to be a must to provide to a spring that makes the freewheel slides back to prevent the lock of the chain in the case a little stone is stucked in between. I hope to have made the right choises and the chain works well, but i'll can say that only after some tests. Any other constructive critical intervention from you and each others will be greatly appreciated.....;) Bye! (sorry everyone for my english, i'm not a mothertongue like you can see) |
Re: CAT330D-L full hydraulic
100% insane build - AWESOME......
