New member seeking help on Serial Number
|
Greetings. I'm a new member here trying to get some more information about my first lathe, a SB 9 Model A.??I want to buy an information card from the SB site, but not sure what how I should be entering this number. I can't tell if the "O" is the letter "O' or a zero. I have uploaded some photos. Also curious if this amount of wear is tolerable, and how to compenstate when machining with it,? not that I would do much about the wear, other than learn to live with it if possible. Serial photo is at the bottom of the post. Thanks again.?

开云体育Hi John, Welcome to the Group. Your lathe is a 1948 Workshop 12-speed Bench Lathe. The 0 is a number: 13140NAR8 ? The wear and how much taper it transfers to the work piece cutting a taper depends on several factors. First thing is to get the lathe leveled up correctly and the tail stock dialed in and then check the alignments and the amount of saddle drop at the wear areas. The saddle will be worn about twice as much as the ridge depth in the Left V-ways from tool cutting pressure. There are write-up’s for leveling and aligning that group members can point you to, when your ready. The ridge doesn’t look to bad for 75 years old. ? ? Steve ? ?

I just went thru this same process with my Heavy 10L The original manufacturing serial number cards are now held by Grizzly. The order page is linked on the SB site. Vintagemachinery.org has a wealth of information. Also check out lathes.co.uk Just recently, a member of this forum posted a link to his own personal trove of documentation: wswells.com On that site is a serial number database with a clear description of how to parse it: 13140N (That's a zero) Serial number, post-1947 within the 9 inch series. A Quick change gearbox R Regular sized spindle 8 Model/series revision number Yours is not currently listed in his database, but the two listings which frame it were built in 1948. You might consider sending your photos and card image to him for inclusion. -- Rick Green |
