Title: Building a chair?
Post by: POSTON WIDEHEAD on September 18, 2012, 08:47:49 PM
When building a chair, is there a rule of thumb what degree to lean back the back? I have sat in some chairs that have killed my back because they lean back a little to far and others are just right and others are too straight up.

I have plans to start putting some backs on some benches.

Why don't you go measure some that are "Just right"?
;)

I don't have something to measure degrees.

Glops and slops don't work when one is measuring degrees. 

Chairs are scary.

Dr's degrees are usually displayed on the wall.

Poston, take your tape measure and a level next time you go to the Dr.'s office. Measure how tall the back is off the seat, then how far the top of the back is from the back of the seat.

If anyone asks what you're doing, just tell them.

The backs on the Hal Taylor rocking chairs I build are at 7 degrees from vertical. Dining chairs will be closer to 4 degrees.

Seat size and height from the floor along with the back angle all determine how comfortable the chair will be but for your benches, I would start at around 5-7 degrees angle since they are for casual seating.

The best way would be to build a mock-up and decide what is comfortable to you, realizing that someone else with a different body size may not find it so.

With a sliding T-Bevel you can take the angle right off of a chair that is comfortable. You don't have to know the degrees, just have an angle measurement.

It has been known to happen before, a time or two.

I thought Okra's comment about Dr.'s degrees being on the wall was spot on.   :D

If you can't measure the "lean" or "degree" of lean, here's what I'd do. Take a 4 foot level and hold it plumb on the top of the back. Mark the point on the floor, and measure the distance from that to the leg of the chair. Most high-backed, "tall-boy" chairs I've done, have been between 3 and 7 degrees of rake.
Moving up from benches? ???

Chairs scare me, so many parts. I did build some adirondack chairs once that came out great, but I got the plans off of lowes website. I never woulda thought a wooden chair could be that comfortable.

Pretty nice chairs, Jake.  You got the seats right.  As far as the back goes, there's a school of thought that rather than a flat back, you put a shallow radius on the board that goes arm-to-arm, creating a curved back.  That back, while usually straight can be fanned too.

You got the arms flat also, which is traditional.  I'm fond of a circular, can-sized shallow recess out at the end.  This minor and still subtle addition has proved beneficial many times when a beverage is involved. ;) ;)

A protractor placed on the seat to measure the rise from horizontal to vertical  might get you an answer.  ;D

BTW, I have an old rocker to restore. An arm and the spokes in the arm. If I had some veneer I'd redo the seat with steamed maple, but that stuff is pricy and the chair ain't worth it. A pizza box full of veneers is about $65 by the time it gets here. No guarantee of the species, it's a mixture. Kind of an A hole way to sell it...but...;)

See a couple tears in the veneer seat there.

She's an old girl. Dad's cousin is 84 and it was his grandmother's. Which means it could have been my great grandmother's, he wasn't sure. Everything about the right arm is pretty much broken. Even the main spoke in front was missing one time and someone tried to make a make shift one. I can turn that to match the other side.
