Re: PC1800 Front Shovel (1/12)
Couldn't stop thinking about the hydraulics so today I built a prototype of the fitting needed in the valve body. Need two hoses for each port, 16 hoses total. Here are some pics of the 45 deg. fitting, #8 ORB to a double 1/8" NPT.
[IMG]  [IMG]  [IMG]  [IMG]  Built it as small and short as possible...I think it should work nicely...so just need to refine the design and build all eight fittings, time to go back to the garage  KP

Re: PC1800 Front Shovel (1/12)
Made a little more progress on the brass hydraulic fittings, got them turned/threaded. Then they were threaded in until they firmly bottomed out on the face of the valve body, this will insure that the angles are milled in the proper direction and that all of the small fittings for the 5/32 tubing are all pointing forward. Next job will be to mill all the flats and then drill/tap the hole for the small fittings....
[IMG]  [IMG]  [IMG]  The ports and fittings will need be numbered because the valve ports will most likely all have different thread start timing.

Re: PC1800 Front Shovel (1/12)
He means each fitting will be machined to fit a given port because the threads will be cut different in every one. If he just makes the fittings and threads them in to any old hole they will point in different directions when tightened down.
Looking good KP!

Re: PC1800 Front Shovel (1/12)
I got lucky on mine but thats what had happend to me to. It took a half hour of threading and re-threading before i found which way they went cause i did mark the sides but never labeled them!

Re: PC1800 Front Shovel (1/12)
What??? haha sorry Joe...I see Reg already nailed the answer for me...I even understand it better now...lol...Thanks Reg, well said!!
One other thing that would affect the orientation of the fittings would be the location of the bottom face in relation to the length and start point of the threads on each fitting, any changes to that would allow the fittings to rotate more or less before it bottoms out on the valve port face. And I know none of the fittings I made are exactly the same.   ( For any technical support please contact RCP57, or just wait until he gets time to figure out my "BS" and then translate it into english!!  )

"The ports and fittings will need be numbered because the valve ports will most likely all have different thread start timing."
I understood what you meant when you said this from a machining stand point but the sad thing is I've never played with hydraulics like this to understand what difference or importance it has.

Re: PC1800 Front Shovel (1/12)
Enough about the boring hydraulic fittings, everyone is most likely sick of looking at them already...I know I will be by the time I finish machining them...lol...
Here are some pics of something a bit more interesting, building the center frame section [IMG]  [IMG]  [IMG]  [IMG]  [IMG]  [IMG]  [IMG]  [IMG]  The two track drive motors ( banebots 256:1 gearbox 540 motor) will be mounted inside the center frame and #25 chain will be used to drive each track.

Re: PC1800 Front Shovel (1/12)
You certainly have one of the better assets that's gives you an edge over everyone else in this hobby, a water jet at your fingertips!

Re: PC1800 Front Shovel (1/12)
The advantage of cutting parts on the waterjet table was very handy....but at the moment both my tables are in storage...long story...never team up with a big company, it seems the bigger the outfit the harder it is to find the right people to manage it, which creates a lack of direction or in this case a change in direction, so for now the machines are in storage. That would be the short and not so sweet version of the story...lol....but hey such is life.
So.....I'll be a bandsawing, drilling, milling, zip cutting, grinding machine for the rest of this build  ...or maybe I'll just get someone else to cut the parts!?

More pics of the build so far.....
[IMG]  [IMG]  [IMG]  [IMG]  When this pin is installed in the track frame it holdes the idler back making it easier to remove the tracks without taking them apart. [IMG]
