Topic tags/keywords: jig dovetail layout

I have been working on a serving tray, for a wedding present. I thought some hand cut dovetails would be a nice touch as well as making the sides of the tray slant out from vertical about 10 degrees. Well, I soon realized the having only one bevel square wasn’t going to work. I have never had much luck at resetting gauges, fences or other devices with the accuracy necessary for repeated cuts. So as necessity is the mother of invention- or at least a reason for stealing someone else’s ideas- I made a couple of these layout jigs. I actually only needed the 1:7 angle but what the heck- when you’re on a roll.

I labeled the angled and square corners after I mistakenly reversed the jig while laying out the dovetails. With the compound angles, the direction the angles, on the tails and pins, were not too obvious.

I’ll post a picture of the tray when it is finished.

Thanks for looking!

All i can say is compound angles on the corners of a project when dovetailing is a test of ones sanity:-)) I learned that lesson doing this: http://lumberjocks.com/projects/17903

nice job cant wait to see the tray, it funny how u have trouble setting fences but doing hand made dovetails is easy for me its the other way i can set up a jig like the leigh and fences to get accurate cuts but when it comes to laying out hand cut dovetails i can do it and i thought i was so smart when i bought the dovetail markers from leevalley well a person off ebay but they’re the ones from leevalley well now they just sit on the shelf laughing at me “hahahahaha sucker u bought us and we cant help u”

Thanks for the kind words, everyone!

Gizmo- I had some scraps from the serving tray, so I just cut the “angle” on the table saw and glued and pin nailed them together. The “angles” are really the ratios I found on the Internet. For soft woods the ratio is 1 to 4.75 and hard woods it is 1 to 7. To get the angle, use a piece of scrap wood or piece of paper and draw a line about 8” long perpendicular to an edge. Measure a distance of 1” from the line, along the edge of the scrap. Measure up 4 3/4” along the 8” line for soft wood (7” up for hard wood). Connect the point on the 8” line to the end of the 1” line- forming a right triangle. The hypotenuse of the triangle is at the correct angle for the tails of the dovetail. I don’t think any of these dimensions are too critical they are just what I found.

Thanks for asking.

I have always use 6:1 for soft and 8:1 for hard. I think I got it form Roy Underhill on the Woodwrights Shop but I’m not 100% sure of that. But I know it was from one of the PBS woodworking shows.

Nice Lew, and thanks for the explanation on how you set the angles.
