|A post blank glued and in the clamps|
|Mortise locations for the upper rails|
|Mortises ready to be cut|
|I find that orienting myself along the length of the workpiece helps me chop vertically|
|But I still use a square to verify|
|First one chopped, cleaned up and complete|
|Boring out most of the waste|
|Cooling down the bit|
|Double mortises done, but center section not yet removed|
|Used a saw for the sidewalls of the middle part and chisel to remove the waste and level the bottom|
If any of you have read this far, it's time for audience participation. I'm getting closer to glue-up and have been giving it a lot of thought. The 78" total length of this headboard is far longer than any clamps I have. I've thought about ganging clamps together to span that length, but it's really tough to do that by myself. So I'm thinking about using the draw-boring technique. I've done this before (maybe only once or twice) but never in cherry wood. So I did an experiment with some scrap that was about the same thickness as my long rails (just under 1").
|Chopped a mortise, prepared a tenon, drilled some holes and made some pegs|
|Offset the holes in the tenon by about 1/16" from the holes in the mortise|
|Tapped in the cherry pegs to draw the joint VERY tight|
|Front side (pegs entered here) after clean-up|
|Back side after clean-up - there's a tiny crack extending from one peg-hole to the other|
So, here are my questions. First, does anybody have experience with draw-boring in cherry? Cherry can be a bit brittle and I'm just a little concerned. I know I can mitigate cracking like I got in my test joint by off-setting the holes so they don't lie along the same grain lines, but I don't like the look it gives. Any my holes for the headboard m&t joints will be much farther apart.
Second, I'm making the pegs out of cherry also. While I'm making them from as straight-grained stock as I can, do I need to worry about them breaking apart from the hammer blows used to drive them in (that wasn't a problem in my test, but my test piece was thinner)?
Finally, the headboard posts (the mortised component) are 2 5/8" thick, so the pegs will be going through more material than in my test piece. Should I be worried?
Any advice would be helpful.
