ML Boatworks RSX380 Outrigger! My first FE wood kit build...

[sammyha]

Keeping the tape on the right sponson, at least overnight. Pulled the clamps, the left sponson sheeting is on.

I must say, there's a lot of techniques for sections of a wood boat build to figure out. Mike says the sponson top sheeting is the hardest part of the build...

It's amazing how they are pumping out all those nice quality RTR's.

They must factor the time and cost to build into the construction/assembly part of the design. Yet they have a nice finished look to them along with great performance. Smh...

Pulled the tape, trimmed the top sheeting. I succeeded in getting all the epoxy joints tight...

Very nice,

I asked about spray foam, no one responded.

Here's my very scientific comparison between four types of foam... [emoji851]

White foam, very soft and light...

Packing peanuts, basically just air...

Spray foam, the heaviest in my study. Structurally the strongest, not really that much heavier. Not enough to be a concern...

Pipe insulation. Firmer and more dense than the white foam. Right in the middle for weight...

Can anyone tell me if the inside sponson to sponson measurement of 14-7/8" given in the manual applies to the RSX380?

The manual is for all three riggers, are they all the same?

Scaling these drawings, they don't look to be the same...

I bought a Map torch and some good silver solder. The real stuff, 45% silver brazing alloy...

And some 1/16" galvanized cable.

The copper tabs are cut out from split open and flattened copper tubing...

I drilled the copper tabs and formed them around the cable. The cable is folded over about 3/8" from the end and silver soldered in...

I'll run the cable on the back side of the sponson rods and put shrink tubing over the cable and rods at final assembly. The copper tabs will be bolted on with the screws retaining the sponsons.

I'm putting a cable on the front and back rods. That's 1/8" OD brass tubing going thru the tub.

I don't think I'd put a rigger in the water without safety cables to keep the sponsons attached to the tub...

Sammy,
What are the cables for, Just safety to keep from losing the tub if you break the booms?

Yes, can't live with the thought of losing the tub...
