The nuts holding the cross-bar for the glue nozzle were removed. The glue nozzle was inspected but the hole was not a uniform circle. The hole in the pie tin must be at least as large as the hole in the glue nozzle. A 1/16” drill bit was selected and used to clear the glue nozzle which had casting debris in the end. The glue nozzle was drilled by hand with no problem. The pie tin had a scrap board fastened in place with a clamp at one and held in place by hand at the other end. The pie tin was also drilled with 1/16” drill bit in the center of the hole cut for the nozzle.

Drilling a hole in the pie tin from the top
The hole cutting damage to the pie tin was reduced by having the scrap board in place. A small metal tag could be felt on the underside of the pie tin. A piece of abrasive sheet was found but not used since it would also remove the non-stick coating. Glue was pushed through the nozzle but there were problems at the top where glue melted and spilled over the top of the heated nozzle. The plastic sleeve at the top must be necessary for a seal.
