Arc layout

[Dave R]

I'm looking for an online source for a diagram or two of the method for laying out arcs using two sticks nailed together and sliding on nails. Anyone got any ideas?

Thanks.

BTW, I know how to do it but I want to send the link to someone who doesn't.

Ron Linton, one of our members, has a wonderful homepage describing how to do this.

It is well worth a visit:
Ron Linton´s homepage (http://facstaff.colstate.edu/linton_ronald/default.htm)

Save it for future reference!

Thanks Ola. I'm embarrassed to admit that I had a link to that site in my bookmarks but forgot it was there.

Problem solved. Thanks again.

WHAT DIAGRAM/ Put two nails on a horizontal line the desired distance (beam) apart. Find center point and draw a 90 degree vertical line above. Put nail at desired height(camber) of deck. Rest your two battens, each on one side nail and the center nail. Screw batterns together locking in that angle. Thereafter put two nails at whatever beam width you want and a pencil held inside the notch of the angle will trace the smar camber arc. Be aware that are slight problems with the dip in the deck such a simple method can create. The arc is geometrically right but- a recent issue of WoodenBoat covers the problem and the fix.

Thanks Buddy but as I said, I know how to do it. I wanted a diagram for someone else. I apologize if I didn't make that clear.

Ola hit the nail on the head.

Dave...If I can make so bold, I think what Buddy is saying is that a diagram may not be required because the process can simply be explained using text (i.e. email Buddy's text to your friend). However, diagrams are always nice...

[Dave R]

I know the description was pretty simple but you don't know this guy. It's gotta be pictures, not words. ;)

[Bruce Hooke]

Yup...I know the type. :D

Of course it's also easy for us all to say that the description is easy when we've all had plenty of chance to see pictures, see the method in action, and do it ourselves...

Our sponsors magazine (#165) details the two stick method in the article on deck framing. ;)
