Except that when you find the pins are different heights on the next = piano.=20 That's why I use scrap maple. I cut a piece to the length of the height = of=20 the pin, and cut a channel out of the side with the band saw so I can = slip=20 it around the pin from the side, and hammer the pin in until it's level=20 with the block. Very like the dowel idea that was posted. Also, I do it=20 when the Titebond sizing is still soft. The pin goes in easier, which is = easier on the plating, and doesn't mushroom the top, and is just as = solid=20 the next day as waiting for the glue to dry before driving the pins. >Of course, you'll need a drill press w/"x-y" vise for accuracy. Nonsense! If you want to drill a hole in the center of a rod for a = punch,=20 chuck the rod in the drill press, the bit in a drill press vise, and = lower=20 the spinning rod onto the bit. Do it gently, and it will self center = more=20 accurately than you are ever going to get it with a cross feed vise. = Come=20 on, Joe. Machinists have been doing this for at least 150 years. It's = about=20 time we stole the idea for our own use. Ron N Ron, Glad to see you've incorporated the Vise Grip with the Dent Puller! Been = using it for years.<G> I've never liked the Titebond for sizing holes. It takes eons to really = get hard. Whereas, Cold Hide glue 50-50 w/water has served me well. Just = different strokes.....=20 The reason I use a punch/hammer, instead of hammering and guage system, = is that the human foible of dinging the top of the pin is more common = with klutzes like me. However, you are correct, in that the height of = various pins does vary! Good point, that the newbies need to know. In = reality, I use both systems. Still like the punch for driving, tho.<G> As for the x-y table/vise, Yes you are correct, you can put the stock in = the chuck and the drill in the vise! I've used this many times. A = brain-fart, on my part!<G> The only if's are: if your chuck is large = enough for the rod. if, you have some kind of vise to hold the drill bit = in proper alignment and is adjustable....... It's just so much fun = re-inventing things, isn't it?!<G> Gawd, I hate it when you're always = right![G] Best Regards, Joe Garrett, R.P.T.
