Now the process of making the stabilisation supports for the pier legs.

Step 1. Cut your pieces to size as accurately as possible, and grind the edges that are going to be welded at 45 degrees for better penetration. Clean up the faces that are going to be internal, as you wont be able to get to them later due to the size of the finished product.

Step 2. By using welding magnets, align at least three pieces together and tack weld lightly. If you start welding straight away, your material will start warping out of shape and alignment. Once you have the entire piece holding together by tack welds, only then start your welds on all the joints. Notice there are no welds on the inside, as its too hard to get a nice weld in such a small area.

Step 3. Grind off as much weld as possible with and angle grinder, be careful not to grind any edges accidentaly. Then if you have a linisher or a disk/belt sander, grind off the remaining weld until you reach a uniform finish. You can lower your grit to get a smoother result and also use it to chamfer your edges slightly so they are not sharp.

Next step, is to weld them onto the pier legs...........

Thanks for looking.
