Trouble Attaching to Spindle of 10ER

[chapmanruss]

Having the hole behind the Logo/Serial Number Plate makes it the version 7 Headstock. So serial number ER59717. The Quill version you have was used for a long time and was the last version. The Tailstock you have was also used for a long time and replaced the ones used for the Wood Extension Table and it's Bracket.

Joe,

The following is from my Thread Shopsmith Model 10's What When and Where posted in Community. It will help explain the difference between the version 6 and 7 Headstocks. It is only part of the posting from June 17, 2020.

One major change that is not readily seen was to the last version of the Headstock. It was also the longest used Headstock during the Model 10 production. The 7th version of the Headstock was the only one to have an opening behind the Logo/Serial Number Plate. It was commonly attached with what was called in the parts list as a Parker Kalon Pin, No. 6x5/16” in the top hole and a standard 8-32 x 1/2" round head screw in the bottom hole. The opening was provided to make installing the switch easier although the Logo Plate was attached with two pins at first. See page 5 of the FEB 52, SEP 52 or MAR 53 Owner's Manual for more information on this. These are the last three Manuals I have copies of and the only ones to show installing the switch that way. There is a 0451 Manual I do not have but the 0151 Manual and earlier ones have the switch installed through the bottom of the Headstock. Anyone having the 0451 Manual can let us know what it says.

The change from Headstock version 6 to 7 occurred between S/N R 64000 and R 64381 for Model 10ER’s made in the Western Plant. The above Serial Numbers are from 10ER’s I have owned. Of course, as discussed previously, the change would have occurred on lower Serial Numbers for 10ER’s made in the Eastern Plant.

I reference this section since it directly relates to your Model 10ER Headstock. The fact that it has the hole behind the Logo/Serial Number Plate makes it an early version 7 that like two I have had with only the pins attaching it to the Headstock instead of one pin and a screw. Looking at just the outside of a Headstock it is not easy to tell if it is a later version 6 or an early version 7.
