Re: Welding Aluminum Boats after your 60's

G&R, I've had to deal with an injured back since I was 19 and thought I was a fork lift- only to learn I wasn't. Since then I've become more and more 'stove up' in the back as the original injury aged and became chronic. Not unusual for a certain percentage of workmen, but last year I learned more a...

Welding Aluminum Boats after your 60's

I doubt there are that many AAB.com forum members who are still trying to weld for a day's work as they close in their 70th year? I am. I tried some retirement and found it to be less than comfortable due to the lack of accomplishment in my days. Felt guilty sitting on my overly round stern, and I j...

Re: Cracked Trailer frame repair ideas

DMc-1, after looking at the welds in the failure points I'd remark some more. The welds don't seem to have much fusion- they're cold lapped in many places. This implies the outside of some of the welds look OK but... in fact their lower root faces- on the web seem to have given up WAY to easily. Wit...

Re: Small trailer re do

Not sure why to isolate Matt? Zinc is pretty close to aluminum on the galvanic scale- and usually corrodes first! That's why we use it on the hull - to protect aluminum. That said, zinc chromate primer paint? thin sheets of plastic film? some bottom paint? I'd say corrosion would be as low a rate as...

Re: Shrink wrap concerns

Mac, if the wrap will see wind- then it tends to shift, flutter a bit and 'shine' the sheer/rub rail where the plastic turns down over the rail. We usually see a shrink job, with straps under the bottom, where the plastic ends just below the sheer-rub rail. That is where we see some wind effect if t...

Re: 250's or 300's???

t;Trout, I'm not suggesting the hull's pitch, roll, or yaw will be different in a given sea- the shape and size and displacement will remain the influences there. The hull's movements will be more easily overcome by power when the higher power ratio is used. Like the difference between the extreme e...

tTrout, another location for tanks that works fine, but isn't as commonly used - is under the gunwales along the topsides, above deck. These tanks can be 20-30 gal each and easily locating 4 tanks helps with roll, if they're full, adds to a use of under the guard deck/sheer clamp/walk around deck sp...
