Peter, agreed, the workmanship on my original cedar FH wasnt great. Lucky i have tools and took to the joints with a grinder and steel cutting disk and 'shaved' timber where req'd to make it it fit. I fixed the issues.
Recently i purchased a pine version, lets see how that goes, but this time if things dont fit, ill ask for new parts as paying the $$ we do, i expect better fitment. i dont have the time atm to be mucking round fixing things up
