so many questions :) How did you attach the brackets at the corners? * steel right angle brackets What did you use for a base? * there is no base on it (its on a concrete floor). this is so if i want to put soil /plants in it, it wont get water logged. it does have a wooden frame around the base, just to hold it in shape. How did you seal the joints? * corners are sealed with clear silicon gel. How heavy was it when completes? * pretty heavy :) 5-10 kgs maybe Does it clean easily? *yep, bit of window spray and it comes up like new, also when they scratched the sides (one of my boys got stuck in it when there was no ladder), it leaves no mark May I presume that the board in the box was a ramp to allow the ferret to exit when done playing? *yep ramp is a ladder see http://waffs.org.au/admin/photos/perspex_ladder.jpg You also mentioned that it cost you about A$160 to build. What would that be in U.S. currency...about $29.95? :) (just kidding!) How did you get the plastic panels...did you have them cut to your measurements, or did you just buy the sheets and use them in the size they came in? *i gave the measurements i wanted to a plastics company, who cut it for me. it is 4mm thick How easy would it be to disassemble this box, if necessary? *very easy: cut the silicon gel with a stanley knife, and unscrew the brackets Just a few questions to keep you busy for a few minutes! Just pretend I'm a ferret and you'll understand! :) *hope thats everything! shona tarvi & tyson [Posted in FML issue 4076]
