An improved (!?) Bedslide

Seeing some recent posts under the EZ SLIDER topic about using tracks prompted me to include a recent change to my bedslide.  This post is partially a repost from TOS (sorry!):

A little over a year ago I made a bedslide pretty much along the same lines as others have posted.  The details of that installation, along with making some upholstered panels for the bed can be seen elsewhere.

Although it worked better than nothing, I wasn?t that enamored of it.  Briefly, the trouble is the lifting effort of getting the slide up and over the bed/tailgate gap and then pulling it uphill across the upward slant of the tailgate. I didn?t like it, and forget about Wifey doing it?

The obvious solution (besides spending $1500 on a pro model) was to do something more along the idea of gadget?s  post elsewhere wherein you use a track or rail mounted to the tie-downs with bearings instead of casters on the bottom of the slide.  Basically it?s imitating the way a drawer glides instead of using the furniture dolly method of casters.

The disadvantage of using tracks mounted is the above-the-bedslide clearance that you lose; mine is now 16.5 inches.  And the tracks are an obstacle if you want to remove the slide and stack large quantities of 48? wide sheet goods.  The edge-to-edge distance of my rails is 47.25?.  The problem would be easily overcome by stacking goods until they approached the height of the rails above the deck, and to then lay a couple of 2x4?s or similar on top of the stack to create a gap so that the next sheet would rest on the 2x4?s at a level that is now above the track.  For fewer sheets, I?ll just leave the slide in and load them directly on the slide since it is above the tracks and the full width is available.

The advantage of using tracks is the WAY easier and smoother sliding of the bed.  Also, using the lower tie-down points of the bed just happens to be the right height for the bedslide to clear the rear edge of the tailgate; the front edge of the slide won?t bump into the tail or have to be lifted over it.

To make mine, I started with garage door track cut to length ($14 for the pair).  The great advantage to this besides being cheap and easy to get (same way I got Wifey) is that its shape both guides the wheels and prevents the slide from being able to ?tip? out if it?s heavily loaded.  For wheels, naturally enough I used nylon garage door rollers.  These are a little more expensive than the all steel rollers, but they?re quieter, smoother, and seem to have better bearings.  I used eight of them for a total of $40.

To mount the track to the bed, I substituted the bolts through the tie-downs with what is called M10X60 SKT FLAT SST  which means they are M(metric) 10 millimeter diameter by 60 mm long with a socket (uses an Allen wrench) flathead profile in stainless steel.  I wouldn?t necessarily of chosen stainless, but I think the foot of the bolts can be exposed to water, so the fact that the ss was all that the dealer had that matched the more important head-of-the-bolt criteria was fine.  The price for four of those plus eight ss nuts was $11.80.  A regular hex head bolt won?t work because it protrudes too far into the channel and won?t allow the rollers to pass by.

I started by drilling 15/32 holes into the track.  This just happened to be a bit size I have, but seemed about right for allowing the bolt head to recess far enough to avoid the rollers, but small enough for the head to have plenty of contact (support) with the track.  If you drill a hole that?s just the diameter of the bolt, the head will protrude too much.

Two nuts are used on each bolt.  One of them tightens the track to the bolt.  This connection needs a thick washer to compensate for the portion of the bolt head that slopes through the hole.  You can see in the picture how ineffective the connection is without the washer on the right side of the pic.  I made my washers by slicing some ?? copper pipe into 3/16? slices.  These fit perfectly, mashing a little upon tightening to conform.

The second nut is to tighten the bolt/track assembly to the tie-down.  I installed the track to be just barely touching the plastic bed liner panel.  It?s easy to fine tune to keep the track straight.  It?s also easy, and almost natural to overtighten, using the liner to snug up the track.  But if you sight down the track it?s easy to see the bowing that creates.  I gave the track a quick spray with black satin to make it look more ?factory installed(?).

The next picture shows the underside of the ?? plywood.  I re-used the piece I already had (and had paid for).  You can see at the right end are two handle cut-outs, which was needed to pull a heavily loaded slide up and out.  I swapped ends and cut a new single handle, feeling that it looked better and would be plenty effective with the new system.  Getting ahead of myself, it rolls so easily that you can actually just grab the slide anywhere on the end and roll it out.

The eight rollers are attached with plumbers tape (metal strap).  At first I used garage door roller brackets.  These don?t work because a) there is too much slop b) the rollers aren?t retained and can fall out when you remove the slide and don?t stay aligned with the track c) and put the top surface of the plywood too proud of the track.  I wanted the surface to be just a little higher than the track?s top surface so that I could make the carpet covering the full width ( app. 50?) so it would cover up the track when the slide is in.  The roller brackets were returned.  Instead, I used strips of  1/16? cardboard (drywall shims) to raise the shaft of the roller 3/16? above the plywood before clamping them in place with the strap.

Behind the third set of rollers is a stop strip which allows the slide to project about 12 inches beyond the back edge of the tailgate.  The fourth set of rollers is set so that slightly more than half of the roller hangs beyond the rear edge of the track.  What it does is to pull the last inch of the bedslide snugly against the midgate like many drawers do that pull themselves shut for the last little bit.  This also creates a little resistance to pulling the bedslide out so that it doesn?t want to drift out when opening the tailgate and parked uphill.  Experimentation will show how heavily it can be loaded and how steep the hill before an additional  brake or stop needs to be used.

The black thing that doesn?t show up too well in the photo is a painted 2x4 with 4 casters screwed to it.  This sits under the installed bedslide and keeps the slide from dropping down each time another set of rollers exits the track when pulling the slide out.  This piece is what really gives the bedslide the feel of a drawer opening and closing.  It acts as the fulcrum to keep the rear set of rollers up against the top of the track so the slide stays level all the time, and of course keeps the slide from flipping with just the front loaded and slid out all the way.  The casters are also shimmed so they just touch the bottom of the plywood.

That completed the bedslide construction, and since the casters used came off of the previous incarnation, the only costs were for the track, rollers, and nuts & bolts.

In the final picture you can more clearly see the ?caster bar? installed.  This is what the stop bar contacts.  This caster bar just pulls out when I want to remove the bedslide.  There is just enough weight on the casters to keep it pressed into place when the slide is in, so it doesn?t move around.

Of course I had to re-carpet the slide and the ?kick panels? of the upholstery (making the upholstered panels and installing the xenon lighting was posted elsewhere); the stuff is loop carpet off the roll; 12? wide by two yards was $50 (and a little something for my neighbor who sewed on all the edging).  There is plenty left over to re-do the plywood piece when this one gets too scruffy.  The HUGE advantage to using loop carpeting instead of cut pile is that it is the ?other half? of Velcro.  The two right angles of plastic framing the propane tank are from Cargo Logic and have the hook half of Velcro on the bottom.  These things are great for keeping things in place (I have four of the pieces and sometimes wish I had a couple more) and you just ?peel? them off the carpet and re-stick them anywhere needed.  I can?t imagine an easier cargo management system.

The first trial was having the Little Lady slide me in and out; that was easy with a (alas!) 200 pound load.  The next test was with a new tool cabinet and chest (yeah!) being loaded up.  I did worry about it a little because the chest was heavy in a relatively small area, but everything worked fine.  When I walk on the slide I can see the track flexing slightly, but nothing seems to be under too much strain.  I don?t know what would give first; the plywood cracking, the bolts bending, or the roller attachment screws pulling out.  Hopefully I won?t find out!

That is nice! You did a great job on the construction of the slider. May I ask a couple of questions?

1. Is their a latch that would keep the slide from coming out if you were parked up hill and lowered the tailgate?

2. What did you do to the inside of the bed? Is it painted? The light color makes the bed look so much better, and the lights help out a lot.

 
Thanks guys!

There is currently not a latch, but as I described, there is a little initial resistance to pull the slide out created by mounting the rearmost set of rollers so that they are just a little farther than the half way point of coming out of the back end of the track.  This makes the slide snug up against the midgate as you push the slide in that last 3/4 of an inch or so.  If parking uphill proves to be a problem with further use, I'm going to attempt to contrive something that would have a spring-loaded pin that would be inserted into a couple of different holes in the track so that one position would keep the slide all the way in, and by pulling against the spring would let the slide come out a couple of feet before dropping back into another hole perhaps...don't know for sure...will probably try to bug gadget for ideas... :)

The inside of the bed is described fully on TOS, but basically consists of 1/8" hardboard panels that have been upholstered with a vinyl that matches the interior.  The panels are easily removable for dirty loads.  Most of the time my bed is used more as a trunk than a work truck.

The lights are normally sold as low voltage xenon cabinet lights for commercial and residential use and are mounted on the bottom of the rain gutters.
 
DPS:

Did you hook up the bedlights to a switch so that the lights come on when the tailgate is opened?

I am working on a similar setup right now on my own Avalanche.

Also, what kind of prep did you have to do to get the white paint to bond on the bed walls? Looks good by the way.

Great mod dps. What keeps the caster bar from moving as you pull out the slide?
 
Supermobile, yes, there is a pin switch for the tailgate.  There is also a rocker switch mounted to turn the lights off, or to turn the switch off then on again when the truck's timer has turned off the lights before I'm ready for them to go off (one could also just push in the pin switch and let it go to re-start the timer).  I'm not sure what you mean about the white paint; there isn't any.  There are upholstered panels using the same cream or beige as the interior of the truck.  I would have liked to find a match for the green/gray carpet, but couldn't in a loop, though the correct color is in the multi-color carpet I did find.  Here is where doing everything in gray or black would have been easier, but I wanted the more "custom" look as well as lightening up the back to see things more easily.

Irontrain, the caster bar so far has shown no signs of wanting to move.  I shimmed the casters (with drywall shim cardboard) just enough that there is a little bit of the weight of the plywood sheet always resting on it to push it down.  Also, the 2x4 sits on the back edge of the black rubber mat which is pretty "sticky".  The bottom side of the plywood is smooth (used A-A plywood) so it doesn't want to try to drag the caster bar out of position.

You're welcome Sam, thank you!  This mod has only been in for about 10 days, so I can't yet tell any long term shortcomings.  But we just returned from a four day trip loaded up with luggage and it was SO much easier to use than the old bedslide that even my wife didn't mind using it (which is saying a lot!).
 
Awsome job!!!!  Looks great!!  I'm thinking of doing something similar.  tired of crawling under or taking the panels off.  Thanks for the info!!
 
Nice, that's what I was thinking about and posted in the EZ bedslide thread.

Nice job, Thanks for sharing? (y)

How easy is it to remove?

Is it hard to get the rollers back in the track once you pull the slide out?
 
The rollers go right back into the track by themselves, if you mean when you pull the slide in and out with daily use; really pretty much like using a kitchen drawer or something.

To remove the slide entirely, you just pull out the "caster bar", then roll the slide all the way out. 

To replace it is easy because you only need to get the forward edge of the slide (the platform) to rest on top of the rails, and it "funnels" itself into that position all by itself if you just walk toward the vehicle with the slide higher than the rails and lower it till it rests on something (which will be the rails).  Now if you push the slide forward, the first set of rollers will meet the track opening.  The rollers will then be about 1/4" lower than the track, but will roll "up" and into the track.
 
Thats a great looking job, do you have any pics of the track attached to the bed.
 
The second photo is an end-on view showing the track attached through the tie-down bolt hole. It's the only shot I've got.
 
I'm sorry I should had been more specific, I meant like a side view pic where you can see the full length of the track and is it just attached in the front and the rear. any support in the middle of the bedslide itself?
Thanks
Dave
 
I have looked around a bit and can't find were to buy the door track, home depot and low's have all the parts you need BUT the track which doesn't come with the door kits they sell so any subjection's.
                                                                      ??? ???
