[QUOTE="SkidRoe, post: 46363, member: 3290"] Another Grapple story: Ever since using my Dad's tine grapple on his BC 773, I have wanted one for my 440B. This was more than just a mild stretch, as my 440 didn't even have aux hydraulics. I was able to source most of the parts from my local dealer (who has turned out to be very supportive and respectful of my frugal nature), so aux's were accomplished in a couple of evenings after work. I priced out a bucket from HLA, the same outfit that my Dad's came from: about $1150 + applicables. Not a bad price, I thought, but didn't have that kind of cash available at this time. What I did have was a shop full of tools (including a lathe & 2 welders), an creative imagination, and a buddy with a CNC laser cutter. You can see where this is going.
