my banker is all grown up now

ok a few have been following this modification and the main objective of the rebuild was to make the rocks fall of the grizzly bars by them selves to save 500 hundred scrapes a day, while maintaining the original angle of the top run to keep the material in the spray zone to dissolve the clay etc.
the reason for staying with grizzly bars is the banker also comes sapphiring occasionally .
the rebuild also grew into the fitting of vortex dream mat which involved extending the lower run.

so we will start when the banker was just a pup and this is how it looked on arrival :

I instantly saw a few issues and made changes to the riffles to get a proper clamp on the mat to stop underflow and a few other odds and sods :

first day out showed me a few things firstly was wet ballz so a guard was made which is also good at catching wild shovel loads

secondly I was impressed with the crate and decided to extend and widen to reduce velocity and give me a area I could pan out separate

as the banker hit its adolescent years I fixed the restriction of 20mm pipe and elbows into the banker which has halved the pump load and now I get heaps of pressure at 1/8th throttle and use less fuel :Y:

sssshhhhh this is my biggest tip for anyone running twin side spray bars . get new risers and drill the holes at a 45degree angle towards the rear of the box this will tumble material against the rear of the box instead of it just getting flushed straight out and almost eliminates all clay balls ( I can run enough pressure to clean my finger nails out instantly )

part 2 is coming now just give me time type it .

Now the rebuild begins as I am over scraping rocks off the grizzly bars almost every shovel full and I am over having so much concentrates at the end of the day its time for change and yes maybe I should have bought a new banker but playing with your tool in the shed is half the fun of gold hunting :lol:

ok disassemble

so I decided to take the grizzys from 13Deg to 26 Deg and also added 2 inches in length firstly side hindge plates

old versus new

next step grizzly bars old Vs new

and also a slip tray to get the paydirt to fall at the start of the bottom run which isn't in the picture :lol: but its a cool pic

then I needed oversize struts to suit the lift kit , old VS new

then to take the full length of dream mat the bottom run grew, and yes I am not set up to weld alloy

then a little trimming for style and the little sloop that could has hit adult hood and will hopefully demand the rocks to bugger off and strip the gold from its dirt ]

part 3 on its way

:Y:

does it work ????? I got no idea :lol: haven't tested it but it looks like it will :lol:




it still lays flat and still only weighs enough it can be carried under on arm



hopefully someone gets some ideas from all this that may help them and their fever :Y:

hope all them photos don't melt ya modem ]
probably only needed last 4 photos but I was happy to share as someone may gain a titbit to alter their rock washer for the better

Nice work mate, time to pull the sluicy sticker off, it's now more your creation.
I'm sure it will do well mate.

yep not much sluicy left there 8)

cant decide what to name it , Bankenstein , frank n beans , bubble n squeak or rock washer 2017.
Any ideas ?

Bankenstein sound like it will fit it to a tee ]

Looking good :Y:

BOB
(bits of banker)
I like bob

I forgot to mention early in its life i replaced the front legs with the back legs and made longer back legs
Also got rid of the stupid bolts that run through the spray bars , so know they can screw out or be turned to change spray pattern

How do you find the mat,Any gold in the last bit or all up the top

Word of advise on a well thought out Modification. :Y:
With your rivets at the boiler box, Replace them
with stainless cup head bolts as the constant grinding
will wear them off.
I always wondered why the inlet on the pipes was restricted.
I build my spray bars with 1 1/2 right to the beginning of
the bars.
Makes a heck of a lot of difference.
Well done on the rebuild. Looks the goods and I am sure you
will be happy with it.

well done mate definitely screams green machine to me, green is go.. go get some gold

Havent run it yet to find out , but the mat is sexy isnt it 8) :lol:

Well seeing this got me inspired and I ordered a dream matt myself.
Bloody quick service, I got an email update on my order within minutes and it's already with aus post on the way.
Top service Gold Rat :Y:

Yep 10 out of 10 for sevice :Y: :Y:
Theres a video link on another topic of the black rocks swirling in the vortex 8) that sold me on the idea , maybe GOlddigg can post it on here aswell.
I think anyone that sees the dream mat in action will buy one , once i get the banker dialed in i might take it to oallen or tuena for a show and tell day.

oallen sounds good mate

Theres another helpful tip in the last photo that helps with quick setup and consistency after replacing the mat 8) can anyone spot it? 8)
My favourite moderator moved this to members only section for me , and i guess i am sharing all my titbits as my way of paying it foward :lol:
I will definently get to a meet up and let the nsw members see the dream mat in action , wont be till after the holidays as i stay away from digging areas during the crazy period.
