For you drilling experts, do you turn your dremel as slow as it will go?
What kind of bit are you using? You don't want to run the diamond bits at a very high rpm, as the metal expands and you can actually lose the diamonds.
I was just going to pick up a couple tile bits
I usually have my dremel running pretty fast like at 8 out of 10, i figure if the bit lasts me 3-4 holes i got my 10 bucks worth out of it....
Remember to keep cold water running on it as you cut and you will be fine. Also, trace the bulkhead with a sharpie and cut on the outside of the line, if you cut the hole too small it can be a real PITA to get it to the right size.
If you have the time to wait for them to ship - I'd recommend ordering some diamond hole saws from eBay...especially if you've got "thicker" glass (not sure what size tank you're doin this with).
As Ryan and I can attest to, drilling 3/8" glass with a dremel SUCKS...but is doable! (took us 2+ hours to drill 2 - 1 1/2" bulkhead holes (about 2" hole) and 1 2" bulkhead hole (2 3/8" hole))
As far as the speed - the bit will usually have a suggested RPM on the package...
Philby, where you guys using used bits or something? I drilled a 125 a few months ago, it had 3/8" glass and took about 10 minutes.....maybe.
i was thinking last night about what would be a good post so i can win those 5 free frags, im not gonna win but i think a good title for a post would be reef tank related tool for loan.
of course they would only be loaned to girs members or someone whos been around for a long time but just isnt a member.
for instance i have a glass bit for 1-1/2 bulkheads that cost me 6 bucks, i would mail it to someone as long as they were a mermber or someone who has a member speak up for them.
of course nobody is going to loan out their 850.00 miter saw, but a 6 dollar drillbit, no problem.
if you thought you had something you could loan out just post it in there.
Waverz - the bits were brand new - but perhaps we got the wrong ones? or maybe our technique was incorrect??
Hard to say man, i use a lot of water and run the dremel at almost max speed, i drill a hole in the tank first then cut the hole rather than drill it.
Craig don't mess it up or you will have to give me that tang and maybe that angel too!!! If you need help with anything man i am here
Hey man if you aren't in a hurry maybe we could do it next saturday at our get together? I know i've never seen it done and would love to.
You know that is a good idea. Maybe I will just drill the 4 for the over flow tomorrow & get the overflow done & we can drill all the reurns on sat night.
We used narrow diamond bits because we weren't sure which tile bit everyone refers to. They took a long, long time.
I have diamond holesaws for bulkheads for 1.5" and less. They work ridiculously well, but nothing near big enough for what philby needed. Got the job done, though.
Here is a link to the ones i use.
1 down, 9 to go. Took about 15 minutes or so. Kinda surprised me when the last 1/4 inch broke & it fell in. I am now no longer worried about having a pool table in the same room. The top brace was about 15 inches wide & shaded too much light so I was taking it out. I had to wack it pretty hard several times with a hammer to get it to crack.
Wow! You removed your center brace? Your balls are definitely bigger than mine own!
I am going to add 4 strips of glass back into it. I ordered them 1 inch wide. I think the 15 inches on a 72 inch tank was a little over kill. I hated the shadow it left. Only the front glass will be viewable so I thought about screwing a brace from the back right into the wall.
BTW 1 tile bit will drill about 2 holes b4 it sux
so we get to view some of the drilling / hole creating at the hangout poker thing?
Ill save1 hole. That takes long enough!
If you are going to crack your tank, atleast make it be the one that we are all watching you cut!!!!! /site/DesktopModules/NTForums/themes/_default/emoticons/smile.gif
