3-Axis Fixture Vise with Quick Acting Screw, Two Stand-Offs, Swing Away Arm with 3.75-Inch Miter Joint, 2.45-Inch T-Clearance - WAC35-SW, Strong Hand

I am new to welding and wanted something to help me set up corners and add legs to square frames. This unit is heavy duty and solid, good enough to hold 1 1/4 inch 11 gauge steel square tubing. The jig is nicely machined to create 90 degree corners and posts. The upper arm swings out of the way and has been improved with a two "finger" set point. Just make sure both fingers are on the work piece and not flipped to the side! The quick release buttons are nice. If you use long tubing you will want to support the ends when setting up the jig so that the pieces are flat on the jig. I put four tacks on the visible surfaces of the joint, removed the piece, flipped the piece over and put four more tacks on the remaining surfaces. I did not otherwise weld in the jig. I did not use the jig for the final setup. Instead I placed the two welded angles on a flat surface and tacked the final two corners using clamps to hold the pieces in place. Only then did I begin welding.I found very little info on building a rectangular table support using square tubing. Basically you can cut the pieces square and butt the corners OR you can try to put 45 degree miter cuts into the square tubing for an improved look. If you butt the corners you will have an open end that may need to be closed or plugged. If you try to miter using a 14 inch abrasion saw as I did, be prepared for frustration. With trial and error and a "square" you can set up a 45 angle cut, but the blade may flex creating a slightly twisted cut. Unless you set up a solid stop, repeated accuracy in length is not to be expected. I was finally able to build a right angle rectangle out of tubing by cutting both opposite sides of the rectangle at once, basically stacking one piece of tubing on top of its opposite cousin and holding them in place using the "gates" of the saw. I was able to do this since the gates of my saw completely supported both sides of both pieces of tubing when stacked. It is important to also clamp the pieces downward on the saw. Of course you need to make sure the combined height of the pieces does not exceed the cutting capacity of the saw. I have not seen this cutting technique described in any book or online so use this technique at your own peril.There are some videos on the weld procession to avoid warpage. I beveled the top and bottom edges 50% of the depth and the corner about 25%. I began by gas MIG welding using a push technique the top and bottom "butt" joints beginning at the inside corner and working toward the outside corners. I then turned the piece for a horizontal "T" or fillet weld on the inner corner. I then welded the outside corner for looks ;).

First- buy this one at a time. Weird, weird pricing on Amazon for this item. One is $211, but a two, three or four-pack costs $300 per unit.This took my table base welding to a new level. Totally necessary tool in my shop now. The first day we used this, we put together three table bases, flipped them over on the floor and found zero wobble. You will get accuracy that you just can’t get with a two-way clamp. A one-inch scrap stock piece works as a spacer to keep the other end of the pieces squared up. While I’d love to have four of these, one is all I needed to get good results. The time saved, not to mention the quality improvement, makes this clamp an essential investment for me.

The one I received did not have any of the casting issues described in the reviews previously via pictures. Mine was clean and works great.FYI I was trying to jig up three 3"x3" angle and the screw legs don't go far enough to make them work with this depth of aluminum angle. However the normal clamp worked well enough to not need them.

This was off by several degrees. By the time I realized it it cost me a half day of work and material. I returned it.

I purchased one of these and like it so much I ordered 3 more! They paid for themselves in the first few jobs! Built very well, accurate, and definitely saves alot of time! Very pleased!

I haven't used it yet, but it seems to be well built. have to be carefull of the button, if you don't press down enough it drags on the threads, same with pushing it down to far. It seems like this might cause it to wear prematurely.

This tool is a must have...

Used it for the first time to clamp 1 1/4" square tube for a welding cart project. Works really well, clamps perfectly. I was only using 2 axis for this job. On the down side, the box it came in looked like it had been dropped from a plane. The t-handle on the lower clamp was bent, I was able to straighten it out in a vice. Should be packaged better considering it's weight.
