The GnATTERbox

[Oztrainz]

Hi all
I found one of these -

At 340mm by 220mm by 130mm, its close to what Carl Arendt proposed here:
http://www.carendt.us/scrapbook/page80/index.html#2

When unwrapped

It gives a "floor area of about 340mm square
An old lump of Triang track hotglued to the floor so that the SupeH can run up and down without fouling the back wall and we have

The front edge of the Triang sleepers is 50mm from the back box wall.

Add a hole in the back wall behind the yet-to-be-built racks and some judiciously placed alligator clips gives:


A few bits of foamcore and a styrene rear wall gives us a cheap set of pallet racks that suit the pallets that came with the 3-speed forkie

The styrene sheet for the rear rack wall is set so that when the pallet is pushed in through the hole in the rear wall and bumps up against the back of the racks, the pallet sits on SuperH so that both can move without fouling the back of the box.

Experience with the RS&W has shown that if you are parallel to and closer than 35mm to a "wall", you stand a good chance of becoming trapped against it, so some "No go" zones have been marked in.
We're gnow ready for the forkie

Build time so far about 4 hours....

Cool. Looks like another fun project.

Love it. And here's me working on something with almost twice as much track on it. I'm going to take a sketchbook to Split and see if I can do it with two straights and a little pallet pusher on strings.

Great work

Time for some moves
First pick up the pallet and cones

Back up and swing left until you run out of room

Then forward and hard right toward the right wing wall

Then back hard left all the way to the left wall

Then forward and right to the front

Then back left again as far as you can go

Then forward right again

Agnother back left to the right front corner and we're ready to shoot for the rack

Forwards and right again - sidewall got in the way

Bcak up again....

and agnother shuffle - FINALLY SUCCESS

Dear John,

How many "punters" are going to get trapped in the mental roadblock,

"whaddaya mean I have to pull a 360-degree rotation turn just to move 6" to the left "

Hi Prof and all,
If it was intuitive anyone could have done it and there would be dozens of'em out there...

Gnow to think up snappy name for a layout built in a John Bull safety boot Boot box from Down Under that reads upside down when sitting there awaiting revelation of its internals - an ulta-miniature Gn15 warehouse layout with operating forkies....

or do I keep the the "Randim" name idea going by using the Randim Selektor -

for example:
1 & 4 = bay 1 = bottom left
2 & 5 = bay 2 = top left
3 & 6 = bay 3 = bottom right
If nominated bay is already taken when stacking
0r
nominated bay is empty when loading out = Spare = Top Right

This gives me some name possibilities-
John Bull Boots (maybe I gneed a Union Jack in there somwhere as well?)
Randim Boot(not a shoe or boot in sight anywhere as load - maybe I gneed some shoebox printies in different colors as pallet loads?)
Randim Bull
Bull Warehouse (not a bovine in sight)
Randim JB
Mini Randim
Bootbox Randim
3-speed Boot
Forked Boot
and so far I haven't got a Gn in there anywhere...
Hmm... More thinking required, but any naming assistance will be appreciated

Hi all,
following a comment made by a visiting friend who reckoned I had more room for the forkie with the bootbox than the original Randim Stackum and Wrackem (at 600mm by 450mm overall). I got the tape measure out and measured from the edge of the front edges of the vertical runners on the pallet racks to the front edge of both layouts

And the results are:
Randim Stackum and Wrackem - 233mm
Bootbox - 230mm

I was surprised that the "swing limiting" dimensions were as close as they were between the two. Given that the forklift is 200mm itself from the front of the tines to the back of the counterweight, the 3mm difference almost became the showstopper and the only way I got away with it here was to significantly cutback the sides of the pallet racks. The depth of the smaller pallets used here is almost the same as the larger ones used on the RS&W, so there is no significant difference in the depth of the racking actually under the pallets.

I still gneed to come up with a better name than "Bootbox" for this "layout". Dallas' suggestion of "Gnational Bull Shippers" is the front-runner at present.

So far the best idea I've had for "prettification" is to just paper the inside of the box with some plain-printed industrial/corrugated iron textures glued to the back and side walls. Remember here that every 1/2mm counts with a layout that is this tight on space. Given that I've only spent 4 hours on this already, I'm looking for quick ways to be able to finish it off well inside another 4 hours. Maybe some styrene racks to replace the foamcore ones and???

A question John , why do you turn the forklift through 360 degrees?
I may be lazy but it would seem logical to me, to reverse away from the train, change angle, then drive over to the rack to deposit the load. Maybe it will cut down on the fun of driving the forkie, or am I missing something else

Dear Steve,

Thing to remember : The rear of a forklift swings <out> on curves

Bearing in mind that there are fences guarding the front and sides of the forklift area, IIRC John has aready identified that there is a "danger area" along each side, and in the front corners (20mm parallel to the fences?)

In short, if you are starting from a position too close to an obstacle,
such as the fences, and your first move is to turn/back <into> the corner,

the geometry of the forklift turn system is such that you simply cannot "change direction" without the tail being locked by the fences.
(you also won't actually gain too much "angular offset" in that first move,
virtually wasting the move...)

Therefore, counter-intuitive as it is,
it is actually better to make you first move a back <away> from the side fence, to gain some elbow (or tail swing) room.

This logically puts your fork on an angle <away> from the palletracks, not <towards> it.

At this point you have 2 hoices,
1 - either continue the "doe-si-doe" moves,
and execute a 360-degree turn in 7-or-so shuffles

or

2 - having gained some elbow room, try to swing back towards the pallet rack,
(IE reverse your "attack sequence")
while not "backing yourself into a corner" again...

Clear as mud?

That's what will make it so "fun" at shows...

Hi Steve and all,
Ahh yes - but I'm even lazier
Yes you can do the shuffle but only for the spots in the rack that are closest to the centre. Here's what you have to do to make the aluminium scrap bale disappear from its spot in the rack-

Starting point is gnow here, with the bale on the tines


First move back hard left until you run out of room


Second move Forward to the far corner - Gnow you can see why the cab on the SuperH is built like a brick outhouse


Third move back and swing parallel to the no-go zone
(Remember- Experience with the RS&W has shown that if you are parallel to and closer than 35mm to a "wall", you stand a good chance of becoming trapped against it, so some "No go" zones have been marked in. )


Fourth move - Gnow for the easy move forward and plonk the pallet onto SuperH's deck


Last move - back up a little


And SuperH is gone....


to deliver its load to here - all 200mm or 8" away


It takes 11 shuffles to do the swing without turning - the same as if you pull the 360 degree turn - but with the 360 degree moves, you can crib some extra room when you can get your forks and the load "out in space" beyond the boot box boundaries

Think I got that. Probably a good thing if I stick to running on rails, much less complicated for my little mind

i have heard of "operation" oriented layouts but WOW!
