General no longer exists ! In Canada Normand Inc. which has 2 stores in Quebec and 1 in Ontario, has purchased the rights to several products and has them made for them (probably Taiwan). The carry some parts but I don't think they have router tables. They obviously do NOT honour the General guarantees.
I work for a large machine shop/fabricator and yes we have minimum charges to set up for tooling, but, most areas especially rural agricultural areas, have a local small scale machine shop that often has older conventional equipment and work for much more reasonable rates that I have found quite affordable for small jobs, more so if you're not in a hurry.
That .013 gap is not acceptable, as Chuck said his is about .003 which is pretty much the norm +/-.005 on cast iron tops. Good luck !
Don't fear your tools, pay attention and respect the tools and avoid injury.
