ensuring steel rectangle tube is flat for DIY fence
As in the title, I've got some 2x3 steel rectangle to use for a Biesemeyer clone. hopefully I'll have some time to work on it soon ,but before that, I was looking for some ideas to sanding the faces to make sure they are flat. I can't inagine that tey're that bad, but I'd think that some kind of milling would need to be done. Would I be able to use adhesive backed sand paper on a granite counter top (when the wife isn't home, of course...)?? If that's a acceptable strategy, any ideas on ow to check, and correct, the tube for the guide rail? it's 72", I'm pretty sure I can't use my counter top for that.. :)
I know there are some Diy Biese clones around here, curious about how you folks accomplished the task. Or, is goning to be good enough as is?? Thanks.
