“I recently had need for a lathe chuck adapter to convert the M33 internal chuck thread to the 3/4 16tpi of my lathe spindle. I’d tried an eBay cheapy but due to the design it didn’t fit into the chuck fully. Then I found an adapter from Wigleys and it was a perfect fit, well engineered and very prompt delivery too. Definitely recommend Wigley and will use them again when the need arises.
