I'm shopping Home Depot. I will get the pattern bit then for sure. But I'm not sure i understand. When I finally am ready to cut the two slots and my jig is perfect and I've practiced plenty of times.............how do I setup it up? This is how I envisioned it. Lay the tank down so the display side is down and the bulkheads are facing up. Somehow clamp the jig down exactly where I need to drill the first hole. Then I will drill a pre-hole with what bit? Once I have a starter hole I will place the router in the hole (already turned on?),set the router depth so it goes all the way through to the other side of the tank (front of tank) and then very slowly move the router along the jig. Does that sound right?
This is where I like the pattern bit better than the flush trim bit.......You are correct the tank will need to be laid with it's face or main viewing panel on the ground......Honestly if you can mask the front panel off.....Even though you'll lay it on something soft such as a blanket you'll find you'll put a small scratch somewhere......
You honestly won't be able to clamp it down.....Clamps are handy, but 9 out of 10 times the clamp is usually in the way somewhere;somehow and makes doing a complete cut in 1 fluid motion hard to impossible at times.....This is where and why I suggested when your at HomeDepot go into the tape section or the paint/hardware and look for double sided tape.....If you can't find it ask them they will know exactly where it is.....With the use of the double sided tape there will be NO need for any type of clamps......You'll apply the tape to either the jig itself first or to the tank surface where the jig will be mounted....It will probably be easier to mount it first to the jig.......Leave the other tape backing on the other side of the tape till your are sure you can line your jig/pattern up easily......Once your sure you know the exact location, and a couple dry runs, make sure the back of the tank is clean, dust free, and pull the tape backing off and set the jig/pattern into place.....I usually press it into place and give it a firm pressing just to make sure it's in place and of course you do the usually shake;jiggle test just to make sure you have no movement.....I like to apply the tape to all 4 surfaces of the jig/pattern that will contact the tank surface......
With that said yes I would then drill my pilot hole.....At this point you'll want to put the router into place with the router bit going through the hole itself that you've already drilled through the tank......Key is there really isn't a dire need to worry yourself crazy about the exact depth of the bit per say....The thing your looking for and want to make sure is the bit is long enough to go completely through the panel your cutting....The key thing you are looking for is to make sure the bearing rides nicely within the pattern jig......Basically your jig will be a rectangular panel with the slot cutout in the center of the panel.....this cut out will be nothing but an exact duplicate of what the back of the tank will look like.....The bit and bearing will ride inside the cut out you made in the jig.....Again the key is making sure the bearing rides nicely in that slot. I like to ride my bearing midway in my jig......I don't measure it out or anything, but a quick glimpse of the the eye you'll be able to tell if the bearing is centered on the diameter of your pattern.....You want to check this with the router sitting flush on top of the jig.....It might sound stupid me saying this, but the excitement takes over and your off a bit.....Well.....You get where I'm going.....Measure twice, cut once!!!!!!!!
Another important area is your jig/pattern.....The jig cut needs to be "PERFECT".....Any wave, mis cut, bobble, will be transferred to your tank cut......If you have little imperfections in your jig, re cut until it's perfect or depending how bad, maybe a little sanding smoothing , a little wood putty, whatever, but take the time and make it perfect......
If I get off my lazy a$$ I'll take the good camera out to the garage, and show you a couple jigs I've thrown together and how they've made life easy and the ease of cutting they make.....I've been working on my control box for the fish room, and I've been getting a little fancy making face plate covers for my Apex Eb8 and also a cover for the display screen for the Apex.....There was no way I could cut it free hand, but a couple cheap jigs, made all the difference in the world to the finish product.....I'll sneak you a couple pics.......
