sam i think my dad made one of those a while back,, not sure which one your refering to but in answering your question the half size would be fine in most respects, but lets say the slats are 3/4 wide and you need 24 of them for the base,, i wouldnt think you would want to make them 3/8 wide and use 12pieces. might a place where you would have to do some math to get things right. as far as length or hieght i think you would be ok the circles are another things.. i am sure others maybe more expeienced in this down sizing a plan theroy..
