Summary description of the tool and perhaps some misc notes about it's existence!

There is a mandatory 3-hour training course that must be taken before the lathe may be used.

It is a 11×25 Advance TY-1125BH metal “engine” lathe, manufactured in 1985, which is actually a generic Taiwanese lathe that is sold under many different brand names. The same basic design is still in production now and being sold by most major hobby machinery manufacturers (Grizzly, Busy Bee, etc), so parts should be somewhat available.

11×25 means that a maximum 11“ diameter stock can be turned over the bed (NOT over the cross-slide however!), and a maximum length of 25” stock can be turned between centres (NOT in a 3/4 jaw chuck!).

Manuals for various almost identical lathes are located in the VHS-Documentation Google Drive shared folder. Each manual is quite different, covering different topics in different depths and at varying qualities of both images and writing, so take a look through them all for the information you're looking for.

• Aluminum
• Steel
• Brass (with special tooling)

Cutting speeds can be determined easily by using this cutting speed nomogram. The original cutting speed nomogram came from Ian at the BCSME.

These links are not an endorsement of a specific vendor, they just happen to be who I bought mine from and they are in Delta.
