I'm considering buying a mid 30s 14" swing RP lathe but it lacks a chuck. It has a threaded spindle nose. Anyone know what thread size so i can begin the hunt for a chuck?

Don't get your hopes up 2 3/4 - 4 in April '31 Circular 10-314-2 Majority of threaded spindles on heavy duty antiques are not something you can buy today

The other parts of this is that even if you came up with the right thread it may not be suited to RP's detail.............. Example thumbnail shows 1910 L&S scan when their smallest 4 pitch thread was 3 3/8 dia. If you brung home a straight hole 3 3/8 - 4, it still would not screw on all the way, simply because L&S used an oversize shoulder behind the thread.....................

Thanks John. I've resigned myself to fabricating a backing plate to fit and buying a suitable Chuck. Will be bringing the machine home this weekend.

Can email the 14" scans from 1931 if you want to private message me that address

Will do. It might make sense to wait until I get the machine home so I can get the serial number which I assume you need to positively identify the date.

Be fine - we can also determine at that time if it is the 8 speed or 16 speed so you get the correct scan
