hopefully the heading is succint enough. I am about to cast a 44" by 21" gfc concrete coffee table top that will be 1 1/2" thick. I want to rest it onto some green (40% moisture) sleeper legs that are resting on their length at either end.
Whilst i appreciate the weight will reduce the table top moving i want to make sure that it cant slip too far.
I dont want to glue due to wood movement and the horrendous weight so was wondering if placing dowels within the concrete and and using a forstner bit of a larger diameter in the wood would suffice and allow for any potential wood movement. I was also thinking of pushing the legs a few mm into the concrete for the first half hour of the cure to create an impression.
The table will be used inside and i am located in the UK where we have a reasonably high atmospheric moisture content although the central heating will be kicking in soon.
Any alternatives would be very much appreciated, many thanks!
