Excellent workmanship!!!
You can always use cargo straps to secure the mold pieces together, for the initial glue up! they work great. BTW You did a great job on that Box Keel, I must say.
When laying down your epoxy bead, tape of with blue painters tape then put epoxy down and peal off blue tape. This will leave a crisp edge. I use this method whenever puting caulk Down to anything. Well done and I enjoy your content!
I’m certainly familiar with that technique but no no particular reason I don’t use it. I think the times I’ve tried it I never get the spacing right and end up with a mess. I should revisit it though. Thanks for the suggestion.
amazing as always!
Thank you Michael.
Didn't even wait to push the like. Don't take that for granted.
It's like working on 2 different timelines.
lunkydog got it. You may unlike at your leisure.
@@Nomadboatbuilding You can't tell me what to unlike, you're not the.boss of me, Mark.
You just gotta plow your field sideways as usual Bob. Suit yourself bud.
@@Nomadboatbuilding Are we starting a RUclips beef,?.,The I whole 2 timelines gets very confusing.
Nope. Let’s nog go there. I can’t keep two streams of lack of thought going either.
Fantastic video. I missed watching this one somehow. Such amazing skills.
Круто!
Paint? Man this 2.4mr keeping its wood finish would look amazing compared to those white boring plastic ones
Just painting below the waterline. It's a practical choice but also it can make the varnish wood stand out even more. Nothing like a little contrast.
Did you glass the inside faces of the fin before joining? I assume that you did. what weight of glass did you use?
Yes I did. I think I used 6 oz or 10 oz. The outside has two layers of 6 oz with doubling over at the leading edge.
why not use ratchet straps as clamping tools?
I do when they seem like the best choice for the job.
Once the keel is attached and sealed, to test water tightness, do you fill the boat with water and look for leaks and swell the planks (Tips From a Shipwright), or just put it in the water and see if it sinks, (Restoring Susanna). Also, "Tips from a Shipwright" made scarf joint using a band saw feathered edges too. I wonder if his method can also be used to make hooked scarfs. I will ask Lou.
These boats are subjected to a flood test as part of their certification. No plank swelling is necessary in this type of construction. You could use a very similar bandsaw jig to create hooked scarfs. You might put a stop on the jig so that you don't cut into the shoulder of your hook I suppose.
Put a hole in the bottom of the boat to let the water out??? I'm not sure I heard that right...😒
You heard that right. The boat has a big hole in the top so it needs at least a little hole in the bottom....I hazard to say, just like you. ;)
@@Nomadboatbuilding Yep. You are correct. It took me a while to remember that you said these boats will spend most of their time out of the water. I assume the hole will be plugged in the water and unplugged to drain on land?
@@TrapShooter68 That's right, but the real hot shots will try to win the race with the drain open just to show off.
Too much yapping by the motherator
I won’t argue with you there.
