Building a cage... am I doing it right?

[I BALL OUT]

If you can get the spacers to workout correctly it can be done. I shoved some washers in there to space it out and it worked 'ok' but didn't look that professional. You can rent a router at home depot and router it out yourself. I ended up doing that with later cages I made. I'm pretty sure this issue right here, along with previously mentioned ones, are why most custom pro built cages come with the overlapping glass doors. You can always go to a hardware store and ask someone for ideas. I have gotten some of the best advice from retired carpenters working the floor at home depot.

I found some 1/4 inch offset hinges for cabinets for like 2 bucks online and they look like they might work but good idea about going to the store to get some hands on them to see of they will work and some advice from one of the old timers at Home depot.
