I have spent most of this summer making parts for a Tracker Pipe Organ.
So far I have made Stop Knobs for the front of the instrument, handles for the pipe stoppers and Morse tapers for the bottom of the pipes where they fit into the wind chest.
Technically the Morse tapers were the most challenging parts. The material is hard maple. The tapers range in size from MT-4 to MT-0. All are about 3 to 4 inches in length.
They were all pre-drilled prior to final turning. The holes were drilled on an antique turret lathe with bores ranging from 11/16 to
7/64. There are a total of 264 tapers on this instrument.Basically I took the dimensions from the reamers used to bore out the registers on the wind chest, rough cut thee large and small diameters with dividers and a parting tool, then roughed out the taper with a gouge. I then used a length of Baltic birch plywood as a sanding block to sand down to the final size.
I have posted a set of images on Flickr showing the process.
