I built a trailer years back (1996 in fact) to haul a small airplane (400 pounds). It started life as an 8' pop up camper, but was transformed into a 12' x 7' flatbed.
After 12 years the plywood floor is rotten, and needed replacement.
So I thought I'd build side rails for it while fixing it up again. Three lengths of 1-12" and one of 2" cost me $75.
I'm using a Hobart 135 with cored wire plugged into a 30 amp 120 vac breaker with an 8 ga 12 foot extension cord.
Once in a while a bead comes out so pretty I think I've finally learned ho to do this. But the next on often glops up so bad I'm embarrassed to let it be seen.
I'm being as consistent as I can, but still can't get consistent results.
I'm blaming it on the wind.
So that's my story and I'm stickin to it!
