Drilling deep holes
In an effort to hide the connection, I thought it be cool (first mistake, being cheeky) to drill from the bottom of a 4 inch thick stock. I used a 12 inch 3/16th bit with a power drill and an adjustable drilling jig. (my drill press doenst have the "reach")the bit came out of the top about an 1/8 off the mark on one hole and about 1/16 for the other.
Can think of a couple of reasons it did this. First, the bit being that long and that thin flexed under pressure and "walked" as it cut thru. Then the drilling guide may not have been dirlectly over the hole, and the above mentioned off target hole may have simply spotted wrong from the get go.
I did start a deep pilot hole with a jig then switched to the long bit.
Is there a better, easier way to drill holes with out a drill press thru thick stock and have it come out where you want it too?
