I've been asked about the 13/64 inch tapered (for wood) drill bit that I use for a reamer. I found that idea on the IDRS forum: cheap alternative tools thread. Finding an appropriate handle is the first hurdle that most folks encounter. For many, an Exacto #5 knife handle (or a clone thereof) is a good solution. If you have access to a lathe, a wood dowel (drill a 13/64 hole in the end) works well. For mine, I increased the diameter of the bit with JB Weld, turned that area down to 1/4 inch so that it would fit into my mandrel handle, and then cut off the extra length. My collar is just a piece of plastic (Delrin) rod. I've been using that reamer for several years now & find it better than any commercial reamer that I've had in the past.
