>>id love to buy a cheap large tank as i mentioned,remove the front glass,add tracks and presto,a siding front terrarium.sounds good but i already see one problem.the front will no longer be water tight and it must because i intend on a shallow pond as one of the features.
A few comments on the above. It sounds like you want to make a strong aesthetic impact with this cage - you want it to look great. A pond in the front is a great way to do that.
In this case you might consider giving up the door and going to top access. Having a door in the front, even a fairly inconspicuous sliding door still detract from the visual impact you seem to be striving for.
On the other hand, don't feel like you need to choose between the sliding door and the front pond. I believe it would be reasonably easy to add a glass lip that the sliding door would rest on and still have a water tight 3" to 4" area at the front of the cage. It will be a bit of a compromise between looks and function, only you can decide if that's acceptable.
>>so id have to not only remove the front pannel,but first reinstall and silicon seal a 4" pannel of glass running along the bottom before i then install the tracks for the sliding door.i dont see how i will be able to install the tracks on the thin strip of glass that i just installed along the bottom.
That is an issue. Spend a bit and use 1/2" glass for the 4" lip and then silicone 1/2" glass track to the top. Problem solved.
>>i actually dont even need sliding glass.just a way to remove the front so i can work/mantain my display would be ok.dont even need hinges,i could just place the glass aside when working but have no idea how to secure it when not.actually no track or hinge idea may be nicer,less harware to obstruct vision.any ideas
Actually, you can still use a track, just a single one. The glass will rest in the track just like in a bypass door, but your lift it out just as you would with a regular sliding door. This is actually not a bad idea and one that will be easy to fabricate.
>>if i decide this is too much work,and just buy the glass and build the cube from scratch,what thickness glass can i use?
I believe you could get away with 1/8", double-strength glass for something like this.
I have no idea on the cost.
