OK, I am trying to build a custom reservoir that will connect to the inlet of my pump but I have some questions.
I am going to be connecting the pump inlet to the reservoir through a coupling and I will be drilling two more holes, 1 as an entry point for the water and another as a filling point.
I got some plexiglass at Home Depot and had it cut to the size I want. I now have 6 sides cut specifically to form a box. I will be using Plastic Fusion to attach the pieces together and then put some silicone over the places where the pieces connect to form the box (even though Plastic Fusion is waterproof, I want to make doubly sure that there will be no leaks).
The problem is I can't decide what to use to make perfect holes for my barbs and the coupling that goes over the pump inlet. I have a dremel and I got a cutoff wheel for plastics which should be good enough for making the hole for the coupling (it is hex shaped) but not for the holes for the barbs.
I have been looking all over town and the net for conical drill bits for a dremel which would allow me to start with a small hole and then enlarge it as I keep drilling but I can't find one for the life of me. I want to use my dremel for this because I don't have a speed controlled drill and I am sure the drill would completely melt the plexi at its default speed. Besides, even if I used a regular drill instead of a dremel, I still would need to either use a hole saw (I don't want to as there is too much risk of cracking the plexi) or a conical drill bit anyway.
Any suggestions? I am not really a handy man here. Making the reservoir is not a problem for me but drilling perfectly round holes (and holes the size I want) on plexi is.
