Hi there, it’s been a while since I posted anything. Truth be told, I’ve been very busy re-building my shop…after the flood. But that’s a different story.
This posting is to show some xmas gifts that I managed to finish just a couple days ago, the Danish oil is just about dry ;).
The idea for these pieces came straight from Jay Hartman’s post.
He said he loved the simplicity of the form and I couldn’t agree more. My wife loved it as well, so I knew it was a good idea to make some for family this year.
I’ve used bubinga and maple, finished with a few coats of danish oil.
Once the bending form and the drilling jig were made it was pretty simple to make a few of these at once.
The bending form is in the back, two pieces, I cut the outside “facets” of the form so that the clamps would have a flat surface when applied. The inner arc is lined with a bit of foam I had, and the entire thing is wrapped in packing tape so that the lamination didn’t get glued to the form. The forms are each comprised of four layers of 3/4 MDF. Cut one, shape it, sand it and then use it as template for flush trimming with router to make the other ones.
The drilling jig was created using the same process, but I attached a base so that I could run it along the fence on my drill press table and it provided a surface to clamp the whole thing to the table. The holes were cut with a Forstner bit and allow the clamps to hold the piece tight to the form to reduce blow out on the underside.
I had to buy a new bit (1 7/8) as my old one was too rough and produced tear out, I also found that I got better results using 550 rpm (300rpm caused end grain tear out top and bottom).
I tried laminations of 3 pieces at 3/32” each, and some with 2 pieces of 1/8”. I found the laminations with 3 layers held their curve better (less spring-back) and I prefer the look of the slightly thicker finished product.
Oh, and I used titebond III, I did a lot of research and the chemistry says it should be just fine with regards to creep.
And yes, I did create a prototype to experiment with the jigs and the drilling…good thing, it looks ugly and will become firewood.
Here’s the one for my wife, complete with the flowers on Christmas morning.
Happy Holiday’s everyone!
