Thanks for all the info regarding using the cat5 - definitely going to go this route. How did the holes on the front of the panel turn out using the step bit? Was there anything that needed to be cleaned up using the step bit? I have the 1/2 inch greenlee conduit punch for making 7/8 diameter holes which I will also be using on my kettles for the bulkheads I ordered.anonymousbrew said:Bi-Metal hole saws. DEFINITELY worth the extra cash.
made quick work of them. I bought a Milwaukee set at HD for like $25 i think? Drilled the front holes and bottom receptacle holes with the hole saws. RTD plugs were done with a step bit, front panel holes were cleaned up with a step bit.
used the same size for 220v30a and 120v pump plugs
Unfortunately alot of stuff I ordered for my kettles is back-ordered so I want to progress with the control panel in the mean time. Only thing I am hesitant about is wearing down the knock out punch making all the 22mm holes on the panel leaving me with a dull knockout punch when it comes time to use the punch for my kettles. Seeing that my kettles are quite a bit more expensive then the control panel enclosure id rather take a metal file to the enclosure and keep the punch for making the precision holes in the kettles. I guess I'm just curious if using a step bit opposed to a punch on the control panel caused any of the holes to come out less precise the you had hoped for?
Sorry for hijacking this thread. I will PM you going forward if you don't mind. I was having trouble finding an answer to this by searching through existing threads. Thanks again.
