As to accessories for your lathe, they are the same for all models within a particular series. When looking for parts or accessories for your lathe, check the unit code. All sub-assemblies and most accessories will have a unit code stamped on them. For example, your compound will have a unit code stamped in the T-slot under the tool post. It will look something like “C 100 N.” Your apron will have a unit code something like “A 100 N” or “A 101 NK” on the front.
The unit code is made up of three parts: The prefix letter or letters identify the subassembly (C - Compound, A - Apron, etc.). The body number of the code identifies the version of the subassembly. The first number is the major design version and the last two numbers are minor version changes. (e.g. 100 - first design, 101 - first design, first version change, etc.). The suffix letter or letters identify what lathe series the subassembly will fit. This is the most important information to remember! The suffixes are as follows:
N - 9 Inch,
K - 10 K,
R - Heavy Ten,
L - Heavy Ten (Large Spindle),
T - Thirteen Inch,
F - 14.5 Inch,
H - 16 Inch.
Now, some sub-assemblies and accessories are used on more than one series lathe. The 9 inch and the 10K lathes share many of the same parts and assemblies. Therefore, the apron (on later models made after the introduction of the 10K) will be marked with a two letter suffix code (i.e. “A 101 NK”). These suffix codes are used in part numbers also (except “general hardware” parts) . For example, the cover plate used on the micrometer carriage stop is part number: PT1209NT1. This breaks down to: “PT” - Part (Assemblies start “AS”), “1209” - The Number, “NT” - Fits lathes 9 inch Through 13 inch, “1” - First version. Sometimes, you can see similar numbers cast into some parts as well. These suffix codes are very useful when checking used parts for compatibility with you lathe. Your Serial number card (type written past the mid 30's) will have the sub-subassemblies unit codes listed.
