I purchased Rockler's plan for a high chair and it's loaded with typo's and mistakes.
- says to taper back posts on all sides at 1.5 degrees and cut bottom at 7 degrees. Then it says to cut then ends of the arms that mate with the back posts at 11 degrees. If the arms are parallel with the seat it should be
- says to taper the inside faces of legs 1.5 degrees, cut front apron at 4 degrees and dado for foot rests at 2 degrees. should be 2.5 degrees.
- says to cut side aprons at 10 degrees, same 1.5 degree taper on leg and to cut the stretcher at 9 degrees. should be 8.5
- back post to be premortised before tapering 5/8" deep for crest rail. Post is 15-1/4" long. After tapering 1.5 degrees you're left with a mortise only 3/8" deep, However it also says to cut the crest rail to length and then remove waste to form angled tenons 1/2" long.
Granted adjustments can be made.... it's just frustrating to have paid for an idea of how a high chair is built instead of an accurate plan.
