at this stage i am at about 3 cm deep in each chamber will try and get the shape of the other chambers in then dig them out to 5cm like recommended, i have been using a drill and a awl so far as all i could afford was the awl and i had the drill and a 5mm masonry bit, i have a multi tool but i found the grinding tools where not man enough for the job but i will use them to grind out the tunnels, the tunnels i will work out where to put them when i have the chambers in place so i can place them so they are not to steep for the ants, i am finding the block a bit tough to carve with what i have but i will not let this beat me, hopefully soon i will be able to afford some more tools,
as for sealing and fronting the block i have been planning in my head a varnished pine base with groves in to mount the glass/perspex and a slopes front to put a plate to put the species name on, i know i am over thinking this but my wife really wants this neat if I'm going to keep it inside so will it really be a bad thing to put glass/ perspex all the way around? if it is a ventilation problem if i was to make a gap of 2 or 3 mm around the sides and back between (not the front of course) the block and glass/perspex what do you say?
and on my design i have 4 hols to add tubes so i can add on to the block for a out world and add-ons when needed i will fix the tubes first and have holes in the side glass/perspex for the tubes,
I can't thank you enough for your help and time you are taking to guide me in this!!
