I want to reline my daughter's`Favorite myself, Brownells has a drill for liners that costs $90.00.Midway sells 3/8" dia drills for relining for only $50., but it's an odd size, all the regular ones are 5/16". Does anyone know the number for TJ's Liners? They used to make all sorts of custom sizes. I don't want to pay $90 for a tool to be used just once in my life, if you get my meaning, or maybe i'm cheap. Being on SSI tends to do that to do you.

What is the caliber of the Favorite you wish to reline? I just relined a 25 Rimfire Favorite to a .22 long rifle with one of the Redman liners  from Brownells. 

If you know how to sharpen a drill bit on a grinder, you can make your own piloted bits. I used a 12" long 5/16" jobber bit from the local hardware store (cost about $12). I made a jig to hold the bit perpendicular to the grinding wheel and ground down the first 3/4" of the bit tip to a diameter of about .235". Then I ground the relief and angle on the step. I also piloted a regular length bit to use to start the hole on each end of the barrel before using the long bit. Worked great and is very accurate.

If you do not have the means to grind your own. I'm sure you could take them to a machine shop and get them to grind the pilots for you for a nominal price. 

BTW... if you are reline a .22 cal barrel, you'll need to grind your pilot to about .215".

T.J.'s has the 5/16" liner, just have to order it direct. His liner is .310" ) I have had a few at .312" )so a 5/16 piloted drill will work. Redman liners are a bit bigger so Brownells sells a drill to fit them.  Best way to make a piloted drill is in a lathe with a tool post grinder. Pilot should be .216"- .217". Do not try to use a drill that does not have a pilot, the hole will wander all over the place. If you are taking a 25 cal out to fit a liner then pilot should fit the bore snug, could be .245"- .250". For the 22 liners I use a 19/64" piloted drill and then ream to 5/16". I found that drills don't always drill to the size you want. This gives .0025" clearance, just right for the red loctite to make a permanent install. I  tried to get the liner out of one after the loctite set up, even with lots of heat it would not move.
The 4130 steel used in liners is a little gummy to machine and a higher speed works best for chambering.
