Hi team,
I'm entering the planning phase of rebuilding the frame of my boat trailer and I'm starting to come up with a few questions so thought I would start a new thread.
Trailer design is pretty simple and over the last 18 months or so I have replaced the running gear thinking the frame was not too bad. However a hole has opened up and it's not good enough to simply cut and shut the rusty bit so a new frame is the way ahead.
First question. It's currently made from 100x50RHS which is around 3.5mm wall thickness with galv coating on it so I'm assuming 3mm RHS. Should I just stick with the 3mm or go for 3.5 or 4mm on the new frame? Will going thicker reduce the amount of flex in the trailer or would a design modification be better to reduce flex?
I'm thinking I will just blank each section of the trailer and partially fill with Tectyl/fish oil and then paint the outside with kill rust or another HD coating that anyone may recommend?
Now for the fun question. Well it is for me any way. I'm currently running a 150amp mig that does ok but is a bit dated.
I'm thinking I stick/tig inverter as I want to learn to Tig one day. Any of the sub $1k units any good or do I need to aim higher with the $$$? No need for ally welding ability just decent DC tig and stick ability.
Anyway that's probably enough to start with as I'm sure I'll find more questions as time goes on. Some pics below of the frame last time I had it apart and the rusty spot.
Cheers
Marchy
