Troy's "Hatchling Rack" (2003)

First of all, let me say that this page is here for the sole purpose of helping others.

I have been helped many times when I just wasn't sure what to do. And many of those ideas were
incorporated into my projects. I am always looking for quicker, cheaper and easier ways to produce
better enclosures and racks. Building them has become almost as much of a habit as my reptiles.

The rack on this page is one that I built 3 months ago. Based on many other ideas and past mistakes I had made.
I DON'T claim to have invented anything on this page. Of course not. Oh my gosh, hundreds have built racks with so many
variations and creative ideas. This rack is based on the idea that you don't have access to a table saw but
you do have access to pre fab shelving. If you want to alter the design and idea to suite your need, go for it.

I would love to see what you came up with. But remember, ALWAYS help others to get started.
That's what makes this so much fun.

DISCLAIMER!: Build this rack at your own risk. I don't warrant the ideas or the process.
As for the wiring part, I have to suggest you get a licensed electrician to do that for you.
I do NOT give wiring advise because everyone wants to blame you for their mistakes these days.
I am just showing what I did.
Ok, enough of the fine, boring print...

Here we go...

FYI: There are a couple of things I did in this design that I now wish I had done differently.
I will point them out as I go. Please be sure to check out my "Ladder Rack" design also.

This is what I built to house my hatchling and yearling corns. Remember, you can click on any photo so see a larger version. A new window will open with the larger photo so you will have to close it to continue.

This design was based on the use of Rubbermaid's 2220 and 2221 tubs. The reason for this is that with the 36" wide shelf, I can put a combination of the two tubs because they are the exact same height. And two of the 2220s = one of the 2221s.

Having said that, I hear that Rubbermaid is now discontinuing all of their tubs. If so, you can use any other brand with this design. Plus, you can alter the width or depth to accommodate the other tubs.

Below is a list of supplies and totals:
The prices and total may vary of course. I didn't include sales tax or shipping
on Flex-Watt. Plus, some items are optional.

Also, when I make this one again, there are a few things I would do differently to improve
the cost and the function. I guess you learn by your mistakes. I will mention these changes
as we go along.

Prefab Shelf Label

.

I used prefabricated shelving I bought from Menards. For those who don't have a Menards, it's like Home Depot or Lowe's. The shelving is only 5/8" thick and laminated on all sides. It's much lighter than the 3/4" melamine and nicer. But it's still heavy. Cost is almost the same when you consider the waist of cutting a full 4' X 8' sheet. You might save a few dollars but remember, this project requires NO table saw and all edges are finished. PLUS, the prefab shelving is more moisture proof I have found

First I started with one of the 6" wide shelves and one of the 16" X 60" shelves. I used a cheap corner clamp from Menards to help hold it square. You want to get your first few boards on perfectly square then the rest of the rack just falls into place.

The 6" board you see to the right will end up being the front/bottom. It's a kick plate. I set it back 3/8" from the edge of the riser just to add a little design to it.

If you want to shave cost off this rack, don't put a kick plate on it. Just start your first level about 2 1/2" from the bottom and you might even get another level on this rack. (Please see my "Ladder Rack" for a picture of this method.)

 


After you get both risers attached to the 6" kick plate, you want to start at the
bottom and work up. This is important because it helps to keep the rack straight plus the distance between shelves is kept more consistent.

Be very careful to get this first level shelf (a 16" X 36" shelf), straight and square. There is nothing supporting the back of this level until you get your screws in place. All other levels will echo this first shelf. Make it un level and all others will be un level.

Now, stand the rack up. Look, you have the hard part done. Yayyy!

Now, lay a scrap piece of melamine sheeting on the first level shelf. Then put your Rubbermaid tubs on that. Now, position your second shelf on top. Put two screws in each side.
I put mine 2" from the left and right edge.

The melamine sheeting gives you a spacer for heat expansion and irregular tubs. Now pull the tub out and remove the sheet spacer. Yea, it's hard to pull it out, I know. Don't panic!


Now test your tub without the spacer,
see how easy it slides in and out???

Continue this process all the way up to the last level.

 

Above I used a square just to double check how my shelves are doing as I go up.

Here I am using the square to mark straight lines where I want to drill my holes for screws.
It also makes it easy to mark the center of the shelf.

When you get to the top, attach the other 6" shelf in this manner.
This will act as "control central" for your new rack.
Here, I have cut two holes with a jig saw to allow the blue jiffy boxes to fit.
(This is the only cutting here.)

This is one of the areas I wish I had done differently. I will get to that later.

Ok, so now we are read to attach the back, and consider heating.
Here, I went with "Back Heat". This is fine for a hatchling rack and much easier that heating
each shelf individually. I chose to run three vertical strips of 3" heat tape down the Melamine
bathroom sheet before I attached it to the back.

If you look very close, you will see 3/4 of the way up, each strip of tape has been severed.
I did this to have a separate control over the top three levels. Something I wish I had done different. Again, more on that later. Read on.

(Update 1-29-04. I have decided that the use of back heat in this manner is not as affective as bottom heat. This applies to this application only of course. There may be uses where back heat is better. But I have now modified this rack to use bottom heat. My tubs were not touching the heat tape in the back enough because of the wide lip on the top of the tub. So the tape was reaching too high of a temp. Your tubs may be different. Just wanted to update this design with my experiences.)

.

Now you lay the rack on it's front and attach the back using small screws.
BE CAREFUL that you don't run a screw through the spot where you attached the heat tape. There is plenty of room for screws, so take your time and mark everything off.
Now it's just a matter of wiring all this together. As you can see, it is a mess back there.
I won't even try to explain this part. To much liability. I hope you understand. I will suggest you have a licensed electrician do it for you. Or better yet, look at the "improvements" at the bottom of the page and avoid this costly mess.

Ventilation Holes in tubs:

I use to drill my holes with a 1/4" drill bit. Then I heard someone mention a couple years
ago that a straight "pencil" style soldering iron worked to burn the holes.

That's just plain brilliant. (This WAS NOT my idea. I don't know who to credit, sorry.)

Here's what I do. I made a template out of a scrap piece of masonite or melamine sheeting.
Drill all your holes in a straight line, (or cool pattern).
Then you can mark every hole with the hot end of the iron.

DON'T try to burn the holes all the way with the template in place. It will weld the template
to your tub making the ugliest looking brown holes when you finally pry it off.

Now, you can go back and "push" in all of your holes where your marks are.
You can see in the photo that the bottom row is just burn marks from the iron
I like to have a small fan, set on low, blowing across my work so I don't inhale the smoke.

Oh, I bought the soldering iron at, you guessed it, WalMart. $9.99

Ok, you have your hatchling rack. So, how fast can you fill it up? For me, I had it full before it was finished. I have two of these racks now. I may build a third with the improvements listed below.

To the left is one of the Rubbermaid 2220 boxes with a yearling Snow Corn we purchased from Katharine and Eli. at AAA Serpents.

IMPROVEMENTS:
Ok, as promised here are some things I wish I had done different. If at any time you can't imagine what I am saying, go to my
latest rack. The "Ladder Rack". There you will see some improvements in cost, function and construction.

First of all, unless you already have a supply of Rubbermaid tubs, don't use them. If you want to use them, go buy them
first before you even start the project.

Second, I prefer the method of just wiring all levels on one heat control. But rather than using the sliding dimmer switches, the
next time I build this rack, I will use a proportional thermostat. Look at the total cost of this rack compared to my "Ladder Rack". This one cost more and doesn't even have a thermostat. By the time you pay for the dimmers, boxes and pilot lights you have almost paid for good thermostat. I will still wire this one with back heat using 3" tape so that no matter what size tub is in what spot the heat is the same. But I will wire them all together and place the thermostat probe on the second from top level. Yes, heat rises and that will affect the higher shelves a little. But so will the fact that the center of the rack is surrounded by the outside boxes making it warmer than the outside.This rack is for corns as I mentioned. They can tolerate a wider range of heat. For example, right now this rack, with both dimmers set equal, is 88 degrees on the top center back and 82 degrees at the bottom center. The outsides are about 2 degrees cooler this time of year. If you want it to be exact, split the levels as I did and use two thermostats.

Another change I could have made was the removal of the kick plate. And then start my first level almost to the floor. Stay about 2" above the floor so you allow room ambient air to circulate under that bottom shelf. And since I won't be using dimmers and pilot lights, I can eliminate the top 6" "control central" giving me more than enough room to add one more level. Also, when you attach the heat tape to the back, leave 6" extra and let it come into the lower shelf and tape it down. That will offset any cold floors.
