I tried the contact cement in the past, I have shaky hands, beginning stages of Parkinson, so I had troubles as you might expect. if I didn't place it perfect the first time there was no second chance lol the Titebond allows me to slide the planking around a little is I misplace it. This is what I love about this hobby everyone has there own way of doing things and you never know when you'll find a new best way to do things yourself. The first ship I built was the San Mateo I was in over my head for sure but I managed to get that ship built. I used CA for the whole ship lol Clinker planked that puppy because I didn't understand how to do it right. I soaked that wood for a whole day and bent the living crap out of it to make it fit, at that point there was still so much tension that CA was the only thing that was gonna hold. lol
