I use the Vega duplicator and templates to get my instrument pegs to around one (1) mm over the final size. Then I sand from 80-320 grit to remove any cutter marks. I have a hard time controlling the diameter as wood is removed as I go through the grits. I am very experienced at doing one thing at the lathe, i.e. using the duplicator to make pegs. I am a very inexperienced wood turner.

For example: My Bb clarinet pegs are 47 mm at the base. They often end up at 45.5 to 46 mm even if I set the template for 48.5 to 49 mm. There is plenty of wiggle room on these instrument stands. But when musicians order a double stand I want the pegs to look identical. Woodwind players, especially high double reed players use precision tools to make their reeds. They will spot variances of 1-2 mm. So do I!

An ideas would be greatly appreciated.

Thanks,
Gordon
