Another Welding/Workbench

admin

Well I finally got to start working on my table this past weekend.I have the frame built out of 1/8 square. The top plate is 30"x60" 1/2' plate.I am going to bolt it to the frame and wanted to know how many and what size bolts to use.I would think fine thread might be better. I am going to tap the top and run the bolts up.The top looks like a rectangle with a cross bar in the center..I will post some pics this weekend when I pull it back out of the corner.Thanks for any help!Last edited by camarotech; 05-03-2012 at 10:48 PM.Syncrowave 250MM130
Reply:Camarotech, check out my table threads. I use just a few finer thread bolts that have flat heads. I used a mag drill to drill thru. I use a counter sink to accomidate the bolt head. No tapping.

Reply:I did that on my 3/4" thick top, but I didn't drill thru.  I picked up a blind hole tap for a couple of bucks. I will say I had to do some tweaking.. In order to use the shallow tapped hole, I ended up fitting the bolts a bit long, then adding washers (or grind them shorter) to take full advantage of each and every thread of engagement.  My table is roughly 2 x 3' and I used 10 each 7/16" bolts.  I like that I didn't have to worry about warpage.
