My boss has asked me to make a conference table for the company and I have a couple things I need some advice on.
He wants a 4ft x 10ft Cherry conference table. Very simple, basically just boards running the length of the table (so 10ft long boards) glued up to make the 4ft x 10ft surface on hairpin legs. Basically this -

No apron. Do you all think I'm going to have problems with sag if I use 8/4 boards? I plugged numbers into some of those sag calculators online and it looks like they are saying anything 1.25" and thicker would be fine but most of the calculators seem to be for shelves and have some unnecessary variables so I'm not sure it's completely applicable.
Second question: what about racking? Normally with a more traditional table I’d be making an apron and wooden legs and the apron/base would essentially eliminate any racking issue. I’ve never seen a hairpin leg table with an apron. They are always just a top with legs screwed into the corners. Is that because hairpin legs account for racking somehow? I was talking with some people in another group and they were most concerned with racking on a table this size. Are hairpin legs just not meant for large tables?
These are the legs we were looking at -

1/2" steel rods. Their FAQ indicates 4 of them can support a couch with 3 or more adults. That would be 600+ lbs. The table top will be 80bf of Cherry. Cherry is 3lbs per bf so total 240lbs. Seems like it should support it no problem. I'll call them tomorrow to confirm though.
