Custom fittings
After piecing together a web of T's and Y's to plumb my latest project I've decided (with the help of a machinist friend) it's time to produce custom fittings. Would there be any interest in these or is there something else you would like to see produced. The items in the photo can be ganged or re-configured.

RE: Custom fittings
It's a good idea.
Tom Cook (Jet Model Products) already makes a similar accessory... [link=http://www.jetmodelproducts.com/accessories.htm]http://www.jetmodelproducts.com/accessories.htm[/link].
Tom's is a different shape (flat) but very useful as you are commenting. I have used one of them on one of my builds and it is very convenient.

.. it would cut down on the amount of T's and +'s needed.

>>the "old" way is:
valve > line to T > two main lines to the aft and two main lines to the nose and then T from this mains to the cilinders.
>>now the way you go with one main block with lots of Ts on is:
Valve> line to Tblock > main lines direct from it to the cilinders front and aft
(lets say you have 4 cilinders to work on the rear..maybe doors..you are looking at 8 up and 8 down line in the lenth of a main one.)
if you do the math the total lenth is way more(x4 of one only main line with t fitings at the end)
that means:
-more presure to fill the extra space
-even more presure cause line walls are elastick and you loose power
-and more tanks to get that pressure from
it doesnt work for me sorry i will pass guys[8D]

RE: Custom fittings
Perhaps you misunderstand my plan, the block is a custom made item to remove all of the T's, Y's and four way fittings however it is not for everyone and I thank you for your input. I have noticed after building many different aircraft the standard assortment of fittings available restricts my layout options. Having the ability to build my own fittings opens up the possibilities to set up my planes the way I want to.
At the end of the day it's what works for you. The photos attached displays the mess I am eliminating with these manifolds but please understand, what I am offering is the opportunity for anyone to have a custom manifold that fits their design.
The manifold is 1/4" x 1 1/8" and total volume is less than 1/2 of the volume it would take to fill all of the T's , Y's, and tubing it is replacing.

Dude, just put the junction block in the back of the plane near all the door cylinders. I know in the f18 I built, 2 junction blocks like this would have elimated $200 in Ts and +s.
