This adaptor allows you to connect accessories with an M33 x 3.5mm thread to a lathe that has a 1 1/4″ x 8tpi headstock thread.

Can I use this adaptor with other thread sizes?
No, this specific adaptor is designed only for conversion from 1 1/4″ x 8tpi to M33 x 3.5mm. Charnwood offers other adaptors for different thread sizes.
What maintenance is required for the adaptor?
Keep the adaptor clean and dry. Periodically remove and wipe it down, along with the lathe's headstock thread, to prevent debris buildup and corrosion.
Troubleshooting
Adaptor is difficult to thread onto the lathe.
Ensure the lathe's headstock thread is clean and free of any debris or damage. Gently try to thread it again, ensuring it's aligned correctly.
Accessory does not fit onto the adaptor.
Confirm that the accessory has an M33 x 3.5mm thread. Check that the adaptor is fully tightened onto the lathe and is not cross-threaded.

Remove the adaptor and re-thread it, using the spanner flats to tighten it securely. Check for any damage to the threads on the lathe or the adaptor.
