These are the front bun chairs and once the blanks have been cut and trimmed up true to uniformed size the central fixing hole is drilled whilst still in the lathe. They are then tapped with an 8 x 1.25mm thread; this is for the bun screw.
The 3 x 6mm fixings are drilled on a manual milling machine using an indexing head as shown.
The last job on the chairs now is to finish the bottoms to the 15 deg offset to the front buns. A small fixture has been made for this purpose. The chairs are mounted with the three bolts.
The chair is held in its fixture and secured on the saw for cutting
