I went down and gathered up a few things to try this morning as I felt something was just not quite the way it should be, so I started experimenting and in fact found a couple of flaws. The shoulder inside the cane was all one size while the collar on the insert was bigger. Even after tapering the whole to make it work, I did not like it. So I got out my calipers and measured everything, TWICE, and then went and found a drill that was just a few thousandths bigger to give me a little glue wiggle room. Take not, you do not want a dull drill bit, it will crack the cane. You do not want a sharp drill bit, it will grab and walk up inside the cane. Lesson learned the hard way. After getting the bit just right, I had four pieces of cane left that I could use, and went to work. I drilled very slowly about a 1/4 down in the cane for the collar to ride down and on. After test fitting each piece to an insert, I put my hot melt on and got the all glued in and spun up. Looking really good. I had also planned to put sinew wrap at the point which I did next and most of them are drying now. I did the one that I had finished yesterday up and did the completion of it with a short cut piece of shrink tubing that I had cut to about 1/2 wide and slide up on the cane before putting the point in, only to find that I could in fact unscrew the point and take it off. So I put the shrink tubing on, screwed the point back on, pushed the shrink tubing down against the broad head, heated it up and took my fingers and mashed the edges down, and have a rock hard, almost footed cane arrow sporting all this weight up front with no where for it to give and break. Simply awesome. I will get a picture or two of the four finished arrows when every thing dries. Man I really like these heavy cane arrows.
