Wine time after completing the shank turning operation on 23 tube mitre cutters in ASP 2004 Powder Metal metallurgy.

Drilling operation on the 28.6-38.1 mitre cutter blanks. Next up is the boring operation to take the wall thickness to 2.85mm.

Dave's frame is returned to the Marchetti brazing fixture to determine the mitre angle between the wishbone topstay and the seat tube. Once this is determined the binder will be mitred, brass brazed to the topstay and then the arrangement will be silver brazed to the back of the seat lug.

Close up of the calibrated rod used to determine the mitre angle of the topstay binder.

Silver brazing the front derailleur braze-on using the new SILVA fixture.

Silver brazed chainstay cable stop with the forty eight year old Strawberry brazing fixture.

New longer seat tube reamer arbors to ream for dropper seat posts are in process. The above photo shows the dowel pin drilling set up. Once the hole is drilled a 5/32" dowel pin is set which secures the Silva HSS helical seat tube reamer.

Pic detailing preform coiling around various size mandrels held in the lathe. A radial hole is drilled in the mandrel into which the 1/16" brass rod is inserted and then with gloves the coils are carefully made. Note: not OSHA approved!

New seat tube reamer bodies for the SILVA no. 031 HSS machine reamer in 30.65mm diameter are on the Bridgeport for tapping the stainless handle threading.
