junk yard hyd grapple build

[ak9]

hi everyone
about a year ago I started compiling materials to fabricate a grapple for my 6' loader bucket.I've read hours and hours on TBN to help me do this build So a big thanks to all .
The hyd portion of the build I used a dual DO3 subplate with 2 o/c 12vdc scv w/one valve vacant for future use.?
The electric side of the build I installed a seperate fuse box from an old 82' VW diesel rabbit ( god I loved that car... rip)I had and supplied power to it with a 4 awg.line knife switched at the battery.Then , from this fuse box to the scv and then to the joy stick which I installed 2 spst momentary buttons.(one for retract one for extend)
The metal fab. part of the build came together by chance when I found on craigs list in March 2011 a person selling old sky hooks $20. (used to hang swing stages on parpit on buildings) . By luck they were the same dia/radius that a tractor trailer rims . I had a few old rims that I cut in half and the welded it all together . It took quite of few 7018s but it is done .
Yesterday I used it for the first time ... awsome what a time saver around the farm.:thumbsup:
Ok , so the reason I'm posting this on the Hydraulic forum is I learned something when building this and I have a question. What I learned is, there is a difference in series vs parrallel when desciding which D03 dual subplate to use:ashamed:Now the questions .. I inadvertently used a parrallel dual do3 subplate and the result was when under pressure fuild flow went to the unused scv/power beyond . Ok so my semi temporary fix was to replace the unused scv with a 2 position scv( Diverter type) and it is plugged on the work ports on the manifold.. is this ok to do ? are there risks in doing this that I'm noy seeing?
For those of you that have a hyd. grapple on a front loader.. how do you have the hoses retained and still keep enough play ?any tricks to share?
thanks

Did you use something like this?

If you were not going to use another solenoid valve for the other section, you should have blocked it off.

Please show pictures of what you did with the valve.

The dual DO3 subplate manifold I used is almost exactly like the surplus center one you linked to except it is parallel circuit .. so I essentially "blocked" it off by using another scv 2 position I had ...It was the easiest fix I had at the time ..The picture in the first post of the 3 position scv is what it was like before I changed it to what is in the picture in this post (a 2 position scv) . I can't think of any reason it would hurt anything doing it this for now... but surprises can get expensive and ?. So, I'd figured I 'd ask the pros on this site ?
thanks

That will work. If it leaks any at all, just screw some plugs in the ports.

Just keep the hoses short and looped out of the way.

Looks good, and it used some scrap, you can't beat that.

I found I needed the most hose length when my grapple was dumped. Curled they had lots of slack. I put a tarp strap from the grapple to the mid point of the hoses. Keeps them from hanging too low when curled and stretches when dumped.
