Looking into tieing in a frag tank

[Joker]

Hey everyone! I'm looking into possibly attaching my portable frag tank into my main system. I know I can drill the frag tank and plumb it I'm worried about messing it up and I don't know which cutter I should use to do so. Is it possible to make the frag tank detachable? So I can take it to frag show in the future. I do not want to drill the tank on the bottom so it needs to go through the side. This is the frag tank I have

Just need the right size diamond bit, patience and a steady hand and just plumb in shut off turn valves and unions closest to the tank to disassemble.

I have the diamond bits already just didn't know if they would work for acrylic.

ohhhh acrylic. Don’t think diamond. I’ve used stepper bits on acrylic sheets but not sure in that case. Maybe someone else could chime in

I've used a bi-metal hole saw go slow. Also go about halfway on one side then drill from the opposite side and go slow again . This to avoid cracks and chips

Drilling plastics creates a lot of heat and the cutting bit you use will get warm enough to "stick" and bind if you don't go slow and allow to cool down. You can do it, just go slow and flow a little water on it as you would drilling glass. I'd use a regular hole saw as the diamond will clog and generate even more heat. Use an old wimpy cordless drill if you have one. My initial thought would be to use a hang-on siphon style overflow to be honest. No drilling and simple to lift off and go portable. I know folks have mixed thoughts on them but if run with respect they don't fail. I do run an Apex or timer controlled tiny pump that will remove any bubbles that could possibly accumulate and break the siphon. I have a hang-on siphon that hasn't failed in over 10 years.

Could always do a HOB overflow option so you wouldn't even need to drill into it.

I have eshopps overflow box in the garage perfect for the job if you go that route.

This.

To the op: what you want to do in theory is easy enough. Personally, I would simply buy two tanks because you're never going to bring 100% of what is in your frag tank to a show. I have a complete show set up that sits in the garage.

That said, use the bi-metal hole saw exactly as described above. Buy a bulkhead and then two unions. One of the Union you will use to plug into your system Normally. The other Union you will simply glue a cap for the proper sized PVC pipe being used and store the unused half of the Union. Don't forget a ball valve on the plumbing side of the system you want to remove the tank from.
I hope that makes sense.

For a 1 inch bulk head I need to use a 45mm hole saw. So for that size in a bi metal hole saw I would need a 1 3/4" bit right or am I wrong

Buy the bulkhead, take it to the store. The one the bulkhead just slips inside of is the right one.

I honestly do not know.
