Hi,Killuar.
If you can get the plans blown up to full size,you could take them to a joiners/carpenters/maybe even a timber yard.I wouldnt think that it would be very expensive.
If not,they should be able to point you in the right direction??
It is an excellent design,and relativeley simple to make,even with a jigsaw and a rotozip.
Hope this helps.
Good luck,P
