Ari, nice looking cylinders. Du you solder the ends or are they glued to the tubing?
What pressure will you use in the system?

The pressure will probably be 20 bar or more, depending when my cylinders start to leak
Cylinders will be silver brazed, here's one that's been brazed:

wow you just keep out doing your self. what will hold the stick cylinder on a snap ring on the out side? are the bolts for the hose adapters end real or just on there and brazed on? thanks for showing us your work.

[Lil Giants]

So what's the bore of the cyls and what size (ID) plumbing do you intend to use?

The stick cylinder and all the others will be attach with flanged pins that are bolted to stick.
Those M1.2 bolts are just for decoration, those hose adapters are brazed.

Cylinder bore is 18 mm and hose ID is 3 mm.

Mostly silver.

[rockNmayhem]

That brass and soldering work is phenominal!!! I sure wish I could solder that clean in that small of a fitting with brass. Can't wait to see this machine operating.

Keep it up.

Ari every time I look at this thread my Jaw drops ..You are really setting the Bar really high now ..Hats off so far a perfect peice of art

[Hemi1966]

Got the boom boxed, and cylinders finished. Now I should get my hydraulic pump up and running to see if there's any leaks on the cylinder tubing.

[Azonic]

Stunning!! Cant say more then that it looks fantastic, great job on the cylinders, hope they are leak free!

[RCP57]

Beautiful job Ari! I'm sure that with your skills there will be no leaks.

[Hemi1966]

I machined the tracks narrower, they are now 72 mm wide which is around 1 meter wide in full scale.
For my eyes they look more realistic now.
Here's a picture of the left track still wide.

[Azonic]

Spot on! That looks so much better!

[Hemi1966]

Here's both tracks done

[aussie mack]

looks great hemi loving the detail ur putting into it

[D8R]

Ari, looks better with the narrower tracks, the bigger machine, the narrower tracks it looks like.

What size is the L-connector on right side, M5?



Like your small connections (brazed) to cylinders, wish I had thought a little more about how to make those earlier. What´s the size of cylinders (good to know if I will build another hydaulic model, easier to find brass tubings).
