Gauging Interest in a value-priced 100 Series Metal Drawer System

Researched making my own drawers for a while...never came to fruition... here are some slides that I found during my searches....they also have quantity discounts. the link "Extra Heavy Duty" have a 400 lbs rating

At this point, forget the server rails unless you happen to get them for free. $120 for 2 sets of 400 lb rails is a good value (and cheaper than the cost of server rails rated for 150 lbs).
 
What's the status of this project? Do you have a prototype built yet or are you still trying to source sliders?
 
Well, the trifecta of workload at my day job, Christmas, and being in an aircast since tearing my anterior talofibular ligament on a run the day after Thanksgiving has delayed progress. Parts selection is done, it's just a matter of getting a day when me and my partner can get together to mock up the final measurements before we send the CAD drawing off to be prototyped.
 
Ok, well at least the project is still on. I'm interested in how the prototype turns out.. Probably me and many others could use a low cost metal drawer system!
 
I haven't read the entire thread, but what is the projected cost? I am in the market for some drawers now, badly.

Dunno yet. We're shooting to be 'value priced', all metal. All depends upon how simple we can engineer the design to keep fab costs down and how well that works in the prototype.

For those waiting on buying another brand, this is truly an on-the-side thing that could never come to complete fruition should the costs not pencil out. So if you have an urgent need... it's probably wise to follow that need. If you're interested and in no hurry then please stay tuned!
 
We finished the 3D work last night on the drawer, latch, slides, and carcass. Only thing left is the latch box and dividers. With that, we will go for fab quotes the 2nd week in Jan. The go/no-go on the prototype will be based upon how the overall price model looks.

Assuming the prototype is made, the plan is to have a blank one-off made for us to work on fitment of slides, top, bottom rails, anchor points, etc. This 'Beta" unit will be field tested with loads. Measurements from that prototype will be put back into the model and a 2nd "Alpha" unit will be built. This will allow for validation that we have a 'manufacturable' unit.

From there, here's what we'd like to do: find two volunteers users (preferably close to PDX) for additional field testing. These two users will get V1.0 units at cost + shipping in exchange for validating the design an providing feedback. We of course will provide full pictures, videos, etc prior to this so that there won't be any surprises on what you get and further encourage you to inspect the units hands-on first. Based upon this feedback, we plan to launch the official product with a 100 series group buy. The size of the group will be determined by the quantity breaks given to us by our fab shop.

Please keep in mind there are a lot of 'ifs' in all of this and at any time the product could be cancelled, so please don't hang your hat on the expectation that this is a sure thing. Our decision will be based upon two criteria: 1) can we provide a value prided product and 2) is the product robust enough to withstand the rigors of our world. Stay tuned, but again, this is a hobby project so please don't count on any specific delivery schedule, pricing, etc. If it happens it happens.
 
Some design questions to toss around:

1) Drawer slides are by far the most expensive single component. We're going to go with a minimum of 250lbs rated slides (per pair, evenly loaded). What is the acceptable level of blind space in the back of an extended drawer? While it's possible to go with full extension sliders, these add costs and the leverage arm creates a growing moment as the drawers extend. Would a 10" blind space (the part of the drawer that doesn't fully expose) be acceptable in a 38"drawer that is 10" deep? That would still extend the drawers roughly 4" beyond the lip of the gate. I don't think extending the drawers further buys you anything as you don't gain any reach once it's past the gate.

I'd rather the drawer not come past the gate. And 10-14" of blind space would be fine with me. 250lb sounds excessive to me. I'll probably not hold a total of 200 in combined weight. I think all my recovery, spare parts, and etc is less than 100lbs.

2) Is there any strong desire to have drawer slides with a lock-open feature? The advantage would be drawers that stay put when pointing downhill. Pretty significant cost option as it moves us up a class in drawer slides. Most likely this would be an upgrade option users could select.

Could be.

3) How important is it to you to have positionable dividers in the drawers? If important, what's the right number? 2? 3?

No desire for dividers.

I'm in PDX, very interested, and would be happy to help when the time comes. Thanks!!
 
Just in case you don't want to reinvent the wheel................
I have a set of drawers in my 100 which I believe are a copy of the Outback Interiors drawers.
OUTBACK 4WD INTERIOR ACCESORIES Drawers
Shake rattle roll test more pics
I purchased these on chance before buying my 100. They cost me $330, when the OI ones were approx $1700.
They were being runout by a company called Red Desert, I purchased a set, told my brother inlaw and he got a set, mine arrived and I tried to buy some more and they were sold out. I then went to probably biggest 4wd show in Australia and saw someone selling them for $1200. They must have bought the rest.
I have included a pdf, I am missing a page but will try to find it. This design would be very easy to replicate.
(Just in case it's easier or cheaper than yours)
It didn't come with a fridge slide, but had all the holes punched for the extra bearings for the slide, and with a slight trim of the drawer the slide would fit in. (designed for this)
The top (12) is plywood covered in marine carpet (with T-nuts fitted for the tie down rails) and is screwed to the metal frame with round head metal threads which go into nutserts. The bearings bolt to the frame and the drawers slide in and out beautifully. The lift up panels (13) are folded gal plate covered in marine carpet.
The rest is folded gal plate with the centre frame (4) having a spot welded return on it top and bottom, so the 3 frame sections (3,4 & 5) all being made the same, minus the return on 4.
The drawers are folded gal sheet, welded corners with welded 2 x 1 approx RHS rails as seen in the photos.
I'll add this pdf with pics and details for a while and see if I don't max out my upload limit
Also as noted these could fit an 80 I believe with just a slightly different top and possibly the fill pieces at the side of the drawers(10). This would give you more sales and better purchase power to make them cheaper for quantity.

^^^ That was quite a score 100TD! Outside of China I'd venture to say you couldn't purchase the materials alone, today, for $330...not to mention the labor!
 
count me in too and If did not take out the 3 row of seats that would be even better. Simple plug and play for the mounting. maybe a place to remote mount the 2m/440 ham radio.

Those are knockoffs of the AO drawers I got from Slee years ago. They are on larger wall mounted rollers, not drawer/server slides. Even the IBM blade chassis slides wont hold up. (empty chassis is 105 pounds) They arn't designed for a dynamic load and they assume a clean environment. The rollers on proper built drawers like this here, are sealed.
 
OregonLC, how is the project coming along? Any prototype built yet?
