I have had good luck removing old pegs by using a steal drift pin. usually you can get on at any steal supply store. If that dosn't work get yourself a good sharp doulbe spur auger bit the same size as the peg and drill it out. use a big powerful drill with a slow speed setting. I use a milwaukee hole hog. the best auger bits i have found have been at wood butcher tools in woolwich ME. they have a web site but you have to call and tell them which bits you want becouse they are not at web store. good luck!!
