Anybody use a Rat Tail File as compared to the Tapered Files that are out there to ream your cork handles?
Thanks Re: Tapered File

You have to use it backwards to prevent it "grabbing" the cork.
Heard of it being done years ago. Since I use individual rings I don;t get involved with that. Herb Re: Tapered File

Have not used a rat tail in a long, long time, thankfully. Re: Tapered File

D avid, i took an old well worn set of rat-tail files and coated them with grit..they cut better than new now and the steel core retains its shape and draws off most of the heat so that very little grit comes loose..then i use a regular tapered reamer to make a final touch up.. Re: Tapered File

David,
This is the set of files that I have modified to be used in reverse in my variable speed drills to ream cork rings, as well as grips. The place where I took rod building lessons used similar files to ream all of their cork and it worked well. So, over time I assembled a set as well. I first used a cut off wheel to remove the triangle handle that is normal on these files. Then, I chucked the small end of the file in my lathe and used a grinder to grind a uniform circular area on the opposite end so that I can chuck that end into a drill and have the file run true. Then, I put the cleaned up end in the lathe and used a grinder to put a sharp point on the small end. This allows me to use a larger file to start with a small hole in the cork and quickly ream it out to the necessary size. If the file gets filled with cork or other dust, I just hold the spinning file against a spinning bench mounted wire wheel to extract everything from the file and keep it cutting well. These are the same files that I started with many years ago and hundreds of rods later they still work as well as they did when I used each of them on the first cork ring or the first grip. [www.rodbuilding.org] Depending on the size of the file, I use either a high speed variable speed 3/8th drill or a high speed variable speed 1/2 inch drill to spin the file. As others have said, I always use the file in reverse so that it does not screw itself into a ring or grip and split it wide open because the file would just screw into the ring or grip without actually cutting out any cork. But, in reverse, the file is just forced into the ring or grip to remove extra material. Take care Re: Tapered File

i just wanted to add that with grit on the rat-tail it does not matter which direction the file is turned, it will not try to screw in and damage the grip.. Re: Tapered File

I salvaged several broken rods from the waste can at a fishing pier and bought some coarse grit sanding belts from a hardware store. I made spiral cut around and around the sanding belt, producing a 6' X 1" strip of sanding belt. I covered the smooth side of the sanding belt strip and the top 18" of each rod piece with contact cement, waited , and wrapped the glue side of the sanding strip around the the glued rod shaft in an open spiral, leaving a 1" gap between each turn. After repeating this operation several times using different diameters of broken rod segments I had a set of concentric reams which have worked perfectly for 20 years. I think the sanding belts were $4.95 back then. Sorry, only registered users may post in this forum.
