I heartily agree with Martin. A scroll saw is the easiest way.
You don't need to spend hundreds of bucks for what we need.
Since this is your 4th 'woodie' I strongly suspect and hope there will be some more👍
So it's worth a moderate investment. Go for it👍
Found this little job on Amazon.com which should do the job nicely.
Not too expensive, about a 100 green-backs ALL IN, has everything we need and I think you can use standard hand fret saw blades in it (like mine😊) which is usually cheaper than the saw manufacturer's replacement blades.🤑
Don't know if you're in Wilmington Delaware or North Carolina (my spies are everywhere😁) but I guess it shouldn't matter re delivery.
Let us know how you get on please😊
Cheers, Doug 😎
BTW How about putting the first three boats in your harbour?
We'd love to see what you've been doing👍
