pipes. One of the reasons for using chairs is they come
ready bent. It's hard to get a really uniform bend without
expensive tooling. I cut the chair up and carefully select
the right pieces to make it all work.
Don't use the chairs that are completely
rounded on top. When you narrow the width of the chair to the width of the
luggage rack, you'll end up with a pointed arch instead of a nice curve.
*Note the plywood jig used to make sure the rack stays square.
