Converting to a swing tongue trailer

Any time I drill holes in a galvanized trailer
I apply a cold galvanized spray to the raw steel.
It seems to hold the rust to a minimum.
Also the fact I don't launch my trailer,
may have something to do with it.

Cast iron is a trick to weld let alone to another steel. You would have to use nickel or braze it. (Unless things have changed in the past few years.)

I think the bolts would be a stronger hold. I would through bolt it.

 

Definitely what he said.

 

I would bolt it. Welding to cast iron can be done with the correct electrode but it is a bear to do. Hot galvanizing is the better option. If you do cut drill into the metal the cold galvanization sprays are about the best thing you can do short of re-dipping the trailer or parts of it. Make sure the metal is super clean so you get a good bond. Now as far as rust in that spot is concerned, I have never dunked my trailer that far up, the ramps I visit would require dunking the axle on my truck to do that. I try to keep the tires dry on the truck. I'd spray it after cutting and again once the bolts are set. Just inspect well a couple of times a year and grind and touch up as needed.

Wow, that is $30.00 cheaper than West Marine. Does anyone know where I can get one of these in the Orlando/Seminole Co. area. Just got a Ghee today and I am a few inches shy of getting it in the garage. I need to find one by tomorrow if possible.

 

Ghee Dave:
If you are just a few inches too long, can you just shorten the trailer tongue and be done with it?

Or just cut it and sleeve it. You'll need a section of box steel
that will allow the existing tongue to fit snugly inside.

 

We did the Fulton bolt on conversion a few months ago and were surprised how easy the install went.  Nice and clean. Used a sawzall type saw with metal cutting blade to cut the tongue and a new  drill bit to make the drilling easy.  All the bolts are thru-bolted though it is not really evident in the pictures.  A quick search on FULTON FOLD AWAY HINGE KITS will turn up numerous sizes and options on where to buy.   Good luck.
