Cutting out the patches

I decided that I was NOT going to bother with trimming the holes perfectly and inserting filler plates. Due to how thin the metal was in some spots, I decided to just cut the patches with plenty of overlap so I was able to weld where there was good thick steel.

A word about quality standards

I am all about doing the best work possible, but I am also conscious about the intended purpose vs the time invested.

Conclusion

We have become a disposable society, but if you have the right tools and a little bit of gumption you can really make things last. It is also fun to find good deals when others don’t feel like fixing things and sell them cheap. Hope this is helpful to you.
