Looking good! How much did you end spending on it?
I do not have a BOL yet.
But in general what I bought:
$0 100 hours in CAD
(winter hours nothing else to do
$408 [1] 4x8 x 1/4" sheet of AR400 , I used almost all of it
$190 on 24' of 3"x1/4" square tube but I used only 6' out of 24' (for the top tube
$52 on 21' of 1"sch40 pipe, but I used only 9' (the solid pins fit perfectly inside that pipe with minimal play)
$31 on 20' of 1" Hot Rolled solid round, but I used only 3' (for solid pins)
$147 on 4x8x3/16" sheet but i used on the grapple only 1/3 of it, maybe less. Its for the plates on the lids, for cylinder protection and bracing. (In the pics I have not welded the bottom parts yet)
$100 (estimate, cannot find the bill) on 24' of 3" x 1/8" square tube (for the bottom)
$150 for 2 cylinders 2"x 6" (shipping included)
$140 for the hydraulic hoses-adapters-TEE's etc, (hoses are CHEAP for surplus center on the pre-made lengths) I was quoted about $450 on NAPA....
$1700 to build the CNC Plasma cutter and upgrade my air supply system!!! (but I could get away with $300 cutting fee and avoid that cost)
$50 in consumables (1st time plasma user, I wasted a lot due to lack of experience, and dry air!)
$30 in color/primer (with air compressor), if you buy the spray bottles it will cost 3x times that.
I do not recall how much welding wire.
EDIT: 2" x 3/8" flat bar for the mounting (SSQA style). It does not cost more than $40
A lot of frustration because of a design fault. that ruined the whole upper section. See the picture
. I had used to go cheap with 1/8" square tubing even though the computer analysis shown that it will break. To fix it I used 1/4" thick sq.tube, with extra 1/4" AR400 plate on top. The point of failure is where the base of the cylinder mount is welded at the top square tubing.
Dont give me the sum, I do not want to know it!
But it sure worth it. Now I have an order for that grapple that I can build for a lot cheaper, (I already have the tubes) and I already have the CNC plasma.
And I feel cooooool!! Its my baby man! My very first one fabricated baby
