I cut my panels with either a saws-all, grinder with a cutting wheel(fastest), or just burn thru them with a stick electrode. And I used perlin where u are gonna use square tubing to weld the panel to
I have a sawsall and would have never though to to use it, thanks for that tip, I like the idea of the the grinding wheel as well on a 4 1/2 inch grinder, i dont have strength to run those 4 foot bolt cutters, the wheel and sawszall sounds light easy and fast, thanks!
