Got your attention? Great! I have a very unconventional task and would appreciate your expertise.
Q: How can I insert a 1/4” metal rod inside a 36” cane shaft?
The project is a cane shaft made from crotchwood Claro Black Walnut. Yes, crosswood of 36” long, grains going all directions but lengthwise. The shaft is 7/8” at the bottom diameter, increasing to 1 1/4”- 1 1/2” oblong diameter.
I have a 12” drill bit, and one thought is to cut the shaft at 22” length, drill into the bottom piece – bottom end upwards, middle section downwards and the top piece – middle section upwards as far as possible, (and re-attach pieces) but the diverse direction of grain can make the bit travel off center, not to mention the roundness of the shaft is hard to clamp down.
Another thought is to rout out a 1/4” strip along one side of the shaft to insert the rod, then fill gap with wood. This will cause an unsightly strip of different grain, but the task would be complete. Again, the shaft is shaped so there are no straight (non-rounded) edges to clamp down.
Saturating the shaft with thin CA glue has come to mind but is not as secure as a metal rod to take the weight of a 200+ lb. person. The 1/4” metal rod w/ epoxy seems to be the most adequate method I can think of (short of not using crotchwood to begin with).
Laminating two pieces of crotchwood with longrain hardwood will be another experiment, but meanwhile I’d like to figure out this task.
I could use a lathe with a lathe chuck and a center rest to hold the shaft in place in order to drill sideways. The lathe is only 34” long, but I could cut the shaft to 22”L as stated earlier if this option would work.
So, now you have the problem. Got any legitimate answers?
