Rockwell 46-450 Help, specs, manual & FM50?

[Lyle W. Kerr]

Good day. I have been on here many times for research and it has been a big help as to the reason I just purchased the Rockwell lathe. I do have a few questions that I am sure are very easy for some on here.

Here we go, first does anyone have or know of a place I can get an original manual for the 46-450? It is all pretty easy to figure out, just would be nice to have on file.

Also what are the TPI/size opening on the drive for attachments? I have not done much of any but would like a chuck to start making bowls with.

Next, I have seen a few threads on here about the FM50-101-C for the 450 1HP, 3 Ph motor. I was just going to replace the motor but this makes way more sense. Doe anyone have a list of additional parts needed beside the FM50? It looks like a good POT and some other parts are needed as well.

Last, anyone know the amp draw with the FM50 @ 120VAC to this motor? And do you loose any HP like you would with a normal phase converter?i.e 1HP 3PH to .5HP single phase 220V.

This is one of my last major items to complete my wood shop in my barn and can't wait to start using it and give my dads old Record Power to my younger brother.

Thank you for any and all help in advanced!

I have that same lathe. All you need to know is over on OWWM.com for documentation. Here is a link to the delta page for lathe manuals, I can't find an exact match for the 46-450 but some are very close. http://www.owwm.com/mfgindex/detail.aspx?id=1141&tab=3

Size is 1" x 8Tpi for chucks. Keep the 3 phase motor and run it with a VFD, it will give you even better control of speed. www.factorymation.com, www.DrivesWarehouse.com, www.AutomationDirect.com/drives are some good online sources. They will help you spec out which drive you need. If its 3/4 horse or more then you will probably get a drive that takes 220 in. Less than that and you may find one that will run off 110.

Thank you for the info, I down loaded the manual on that web site you listed, it was very close to the 46-450. Thank you. It looks like the FM50-101-C is the perfect fit, it will do 120V for the 1HO motor, just not sure if you loose any power when you do this like with a phase converter.

Any ideas on a good reasonable chuck to look at? $ Quality?

Oneway Stronghold will be more chuck than you will ever need on a lathe of that size, prolly about $275. The various Teknatool chucks are decent also.

I have the Barracuda2 from PSI and am happy with it. http://www.pennstateind.com/store/CSC3000C.html

Thanks for the help, once again.

I got the lathe in my barn, but turns out I really need to get a floor in there. The floor is dirt and all of my other equipment is on plywood, the lathe is much heavier and just rocks on the plywood and dirt. I guess it will be a little bit before I can use it.
