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

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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.

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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.

Re: CAT 374D L
 

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

Re: CAT 374D L
 

Made some plumbing today:)

Re: CAT 374D L
 

Very neat!


What do you use for brazing?

Re: CAT 374D L
 

Mostly silver.

Re: CAT 374D L
 

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.

Re: CAT 374D L
 

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.

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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

Re: CAT 374D L
 

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.

Re: CAT 374D L

Re: CAT 374D L

Re: CAT 374D L
 

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?

http://i327.photobucket.com/albums/k...L/IMG_0791.jpg

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).
