Welding table top question

admin

As I am making my frame to hold my new 5/8 inch top and almost ready to put it on top of the frame I was thinking on how to attach it. I really don't want to weld it in case I was to move and could take it apart and painting it would be easier also. I have some over sized piping nuts that I thought of welding to the bottom side of the top, then weld some heavy angle to the inside of the frame and bolt it up to each other. Any cons to this plan? Here is some pictures of the progress. I had the local shop with a laser cut it out for me and I bought one of those new miller work station clamps for it. Should work out good I hope. The frame is 2x4 3/16 tube that was given to me. Can't beat the price. Attached Images]Lincoln PT 225 Tig
Reply:Just tack it on in a few places and when you want to remove it, cut it off. With a table top that heavy it won't need very much weld to hold it on. Maybe 1 inch long beads in 4 or 6 places.
Reply:...well...I don't really like to weld table tops at all....not likely you can do it without some distortion...and no fun crawling under to grind/cut off the welds later...  I like to either drill/tap a few holes from the botom of plate...(blind holes if it's thick enough)...or drill and countersink a few from the top...use some flathead allens to hold top onto frame...perhaps weld or bolt some angle pieces to the sides of base/frame...  Doug...Dougspair
Reply:Drich,     I'm in the same place on a project I'm working on.. I'm working with a 3/4" thick top.  I thought I would drill and tap holes in my top, then screw from underneath, leaving bolts a bit long.  My plan was to then grind / file the extended threads flush with the table top.  I was planning on using 7/16" threaded bolts, with 1/2" thru hole in my framework below. Doug,     I didn't really think about tapping blind holes.. Looks like a 7/16" bottom tap runs about $20.  Is that really worth it on a table I'm going to be working on?  Maybe I'll tap a piece of scrap and check out the long thru bolt and grind appearance...Another option for me is to use countersink bolts from the top, but doggone countersink bit in large diameter is expensive!   I'm trying to figure out if that's a tool I will use again or not..  (I guess I could go smaller diameter bolts, but where's the fun in that?)--zip
Reply:Here is just a recommendation but why dont you position the top where you want it and then on the bottom inside corners weld some lugs to the top only. The weight of the table should keep it down and the lugs will keep it from moving side  to side.
Reply:I welded angle iron to the inside of the frame and welded the nuts to the angle iron and then run a bolted from the top down, that way if I need to take a bolt out to get it out of the way it makes it easy to do.Terry
