at 1st, i thought i will just install all the tubing on the excavator with just nylon tubing as final. i saw lots of other builders are putting in copper tubing. but i was to lazy to make one, then it sudden came to me, why not i gave it a try.
just try 1 pcs, then it was all the way go....
no wonder, i realised how fun and nice looking to have those copper tubing installed.
be heading to spray paint shop later, to have it colored. let see how its appear out.
