Trailer drawbar modification

Postby Paul B » 20 Jan 2018, 17:24

Just got my new Honwave T38 and will need to modify my trailer as it was set up for a T32
,
I cannot move the winch post far enough forward so that the transom will sit directly above the rear keel roller,
I want to be able to tow the sib with the engine on the transom , hence why it’s important for the keel roller under the transom

The current draw bar is welded to the axle and side beams of the trailer, so it’s not really ideal chopping it out and putting a complete new length in, So I was thinking of putting another length of 50mm box section onto the top of the existing drawbar , bolting through and welding in place , would you think this is sufficient and safe or not

Or have you a better idea :thumbsup

Is your trailer galvanized?
If so be very careful welding it, unless you plan on a hospital visit :D
Bolting should be enough and a much safer option.....

Yes it’s Galvanised. And yes I’m aware that you need to grind the coating away, or it gives off poisonous gasses :thud , I wonder how many people don’t know that fact , :thumbsup

"Metal fume fever" as it's commonly known is not uncommon with the unaware.
Normally the symptoms will pass in a few hours, but in the most extreme cases it can be fatal!

Symptoms include chills, shaking, a slight fever, vomiting and cold sweats.

Stopping what you are doing and getting fresh air is usually enough and you should be back to normal after 4 hours.
If not then it's time for a check up!!!!!

Unfortunately oxidized zink plating, as found on old boat trailers is about as bad as it gets.....

Hi Paul B
My old man extended the front of the trailer hitch on his current boat - must be 15 years back.
He sleeved a piece of box section over the original trailer front end and remounted the winch post.
Overlap is around 3ft.
It's bolted thru every 6 inches or so.
Not galvanised but it's performed faultlessly.

Paul
Once you've carried out your 'mod' I'd recommend giving the weld and new section a good coat of cold galvanising spray .... something like this https://www.toolstation.com/shop/p60070 :idea:
I've used it with decent results ...... not as good as proper galvanising obviously but performs well for the cost :thumbsup
:cheers
