The Reservoir Tanks - What they are and how I made em:
|
|
|
|
This is one of those things people REALLY wanted to know so I put it at the top if the list of parts. What are they?
|
|
|

Du-Bro 20oz Fuel tanks used in R/C Aircraft, and Heli's. I knew from the time I started on this project I was going to use aircraft fuel tanks, but I didn't know what size or shape. I got these in from Tower Hobbies. Their odd Shape posed a bit of a problem and didn't make me too happy, but I worked for a week plotting and planning how I could use these. The reason I had 4, was DH3 Originally was to have 4 loops.
|
|
|
|
|
|
I spent many days lining up and arranging the tanks on the case in various places to see where I could get em to fit.

This WTX case is big, but it did pose some tight space limits that I wasn't counting on. By the time I redesigned the entire cooling system layout and design and ditched the 4th loop, I found only 1 way I could fit all the coolant tanks in the case, and that was them all standing on edge, but now I needed to get those damn 1/2" holes put to use for something. Off to Ace Hardware!

After walking around with a future res. tank in hand I tried every fitting and plumbing thing on it to see what may work. I messed with stainless steel braided hoses, copper, brass, iron pipe, everything. Then I found something that may work ( thank god, Aces was closing for the day and they wanted me the hell out :)

That's it folks! it changed a bit ( as you will see down the page), but the basic design stays as is. Its nice cause I have a big area to pour the coolant into and not splash all over the case.

Ok to get the rest of the fittings on the bottles I also made another run to Ace Hardware, BTW they DO know me by first Name!
|
|
|
|
I used 3/8" Hose fittings with 1/4" NPT Threads. I drilled a hole slightly smaller and threaded these into the bottle to help provide some added stability to them.
The Outgoing fitting is in the center of the bottom. the fitting BARELY sticks up over the bottom of the tank. The Rear fitting is for the return run.
|
|

At the same time I was noticing my measuring skills needed some serious work. ( before I bought the calipers ) The Front hole is NOT 1/2", its slightly smaller. So what I needed to do was ... go BACK to Ace and find a new way of doing the front fill portion.
|
|
I went with a 1/2" "Flange" type fitting to a standard 1/2" Pipe fitting. OMG did it work nice! ( in the pic they are drying after being Glued with Plumbers Goop)
|
|
|
|
At this point I was getting ready to take the case parts to the Machine shop to have em plasma cut, and I sized it all up to get the hole cut for the 3 fill caps.
|
|
|
|
|
|
While all the metal stuff was out being cut, I finished up the res. tanks
|
|
|
|
I went and glued it all in with a generous dousing of plumbers Goop. ( this suff ROCKS, its like Rubber Cement on Crack!) I coated the threads nicely so it sealed all the way into the bottle. Since I am the most impatient lazy bastard around I put them into the oven at 160 Deg F for about 8 hours to cure. Pizza's Never quite tasted the same, but eh.. that comes with this gig :)
The Cooking of the res. tanks went GREAT ( unlike a later cooking problem )

Look for a "Joe's Cook Book of Cooling System Parts" at your nearest Grocery store soon!
the Top parts of the res. tanks aren't glued yet as they need to be put into the case first.

I used big Galv. Steel washers under the caps to make up some space I needed, and also it made it look a lot better.
