Thanks for posting the good and the bad.

I always feel that when things go wrong, others can learn more than pics of the perfect build.

That's why I post on my build when things go right and wrong so others may get ideas and learn from my mistakes!

Solution - Plan modification needed

Add these to each corner. The frames are essentially free floating so technically they are not structural but they are forming members (scantlings). A simple stress relief cut with a stop hole to prevent cracking beyond the cut is all that's needed to prevent the shrink problem. Ideally this would be a zig-zag cut but without a lazer cutter that would be pretty tough to do.

I'm going to do some minor grinding touch up and then fit the new flange. Once it's welded up I'll know how well this works. For sure, the minute I cut it, the frame opened up to within 1/4" of the original size.

I may be able to fix the other two frames the same way, without having to remove the flange.

Whewwwww.. Long day at the boat yard, I'm beat...

Here's the modified jig -

Radius view -

Welded up with deep penetrating welds -

Image

All my ducks in a row.... Finally...

Image

Other side -

Image

Way better now --

Image

Even though they are all in good shape now I'm still going to cut a 2x4 spreader for each of them before I put the T-Bar on it.

The next thing I have to do is put the stiffeners on frames 5 and 7 and then I'll hang the stem and lay the keel.... Oh shoot, the minute I lay the keel I'll be a boat owner again.

I think I'll just leave them. Its one of those, "it's working, stop messin with it" things which is akin to putting lipstick on a pig. The flange will keep it from moving any more than what it is now.

I have to keep reminding myself that these frames (1-4) are just inside forms and don't really do much for strength. 5, and 7 are structural. 6 is kind of a combination.

It's hard to percieve what I'm saying but you'll see it when I start putting the longitudinal T bar on.

I wasn't sure if you would weld up the slots after the boat was skinned and flipped and it would hold it's shape at that point

Your posts are great reading for us even though most will never build an aluminum boat,but it will also help those that will

upspirate: Yes after clamping them down tonight I decided I would go ahead and weld them up after I flip it.
Got to playing with the erector set tonight. Sorry about the fuzzy pic, I was shaking with fear... There will be better ones soon, this was just a mock up.

Now the question is, is that light a the end of the tunnel daylight?

Or is it a train about to run my rear over. LOL

Here's where frame #7 belongs. It's now notched and the stiffner added. It's done..

Image

This is a shot of the stiffner. I've got to read the plans again but I'm pretty sure this gets welded all around. I think it's the only acceptable hard point on the boat.

Image

Just for info, that 1-1/2 circle cutout at the top frame is what's known as a rat hole.

I let the frames sit like they were for a week and slowly but surely they returned to their closed up state.. I took one of the frames back to the folks I got the metal from to try and get an idea of what really happened.

After a few minutes of head scratching I asked if maybe they forgot to stretch it after they flattened it? They called their supplier and explained and then gave me 5 new 4x8 sheets of 1/4" 5052 H-32. The 5th sheet was for my troubles. I've got them all recut and just have frame 1 and 2 to finish up now.

Yep. I'm one of those guy's that just can't say "Good Enough". I'd probably spend as much energy and time fighting it later.

I had a friend ask me to make him a new dash for his off-shore hot rod. He supplied all the gauges and dimenisons so all I had to do was lay it out and cut it. The bezzels are getting replaced.

Here's what I started with -

Image

And this is what he got -

Image

As for the Canyon Cruiser, I fixed the frames instead of remaking them and they're fine now.

I also finsihed putting all the stiffeners on the forward frames and got the shop ready for the next phase. I sure wish I had more room so I didn't have to keep juggling things around all the time..

Heres the forward frames in place and blocked -

Image

Here's what I've done to keep the frames straight and true -

Image

If I get the yard work done tomorrow I'll see if I can't get the stem welded in. I hate vertical welding Aluminum, overhead is even worse and I've got some of that to do too.
