i have a chair that has been in my family for a very long time, it is a simple rocking chair, I stripped the finish off, disassembled and sanded every piece of the chair. the chair is held together primarily by wooden dowell pins. 2 of them broke during disassembly. im wanting someone to give me a rundown of re assembaling a chair held together by dowell pins. should i drill out all of the old pins, or use the ones that arent broken, also what is the usual procedure for gluing the pieces back together. any help would be greatly appreciated.
