Beefy faceplates with set screw?

I'm doing my first very large diameter turning (30") using a 6" Oneway faceplate and it occurs to me that a lot of the cuts I'm making would feel a lot more natural if I could stand on the other side of the lathe and turn in reverse (headstock and ways wouldn't be in the way). However, the Oneway faceplates don't have set screws to lock them on the spindle for reverse turning and a quick search this morning didn't turn up anything from any other manufacturers. Am I missing one? Anybody know of a source for large faceplates (6"-10") with set screws? I guess I could just try drilling and tapping the Oneway one myself, those are ideal faceplates in every other regard- kind of silly that they didn't also include that in the design.
 
Just drll and tap it. I’ve done so for chuck bodies and inserts. I hollow in reverse, and also my lathe (Nova Galaxi) has somewhat aggressive braking (which I like), both requiring a set screw. The 6” faceplate that came with the lathe has 2 set screws - it is not as stout as a Oneway but works fine.
 
It should be fairly easy to tap and thread the oneway steel faceplates, an alternative that would be even easier to tap would be to use an aluminum faceplate, available from several manufacturers.
 
If you have a long enough drill bit of the correct size tapping your faceplate shouldn't be a problem. Oneway makes 10" faceplates that use their taperlock adapters ready tapped for setscrews. Either way, you may find that a blank that size may overcome the braking power of your vfd unless you have a braking resistor or slow down the deceleration rate. Oneway
 
If you decide to drill and tap your own, then do be aware of where the set screw will land on the spindle. You'd like to avoid the spindle's threads.

Do you have the ability to turn outboard on your Oneway?
 
Oneway has a smooth 34mm collar behind the spindle threads which is used for centering. There is a channel behind that collar, which is where the set screw should go. It is present on both the inboard and outboard spindles.

Thanks all for the info so far. I had seen the Oneway 10" plate + taperlock adaptor but being a Vicmarc chuck man myself, I wasn't sure if their adapters had locking set screws. I'm turning on a PM3520B with the short extension in the lower position.
 
Thats odd, my Oneway 6 inch faceplate does have locking set screws. I turn in reverse with it occasionally. Maybe you have an earlier version that didn’t have set screws?
 
I bought my Oneway 2424 in 2004 - the spindle has the channel for the set-screws both inboard and outboard. In 2016 I bought a 8" faceplate - it has two set-screws at 180-degrees. Had you asked, I would assure you the channels are in the same position to accept the set screws that are a always a feature - no chance of an omission

Can't imagine Oneway not catching that gross an error - I'd be on the phone to Oneway.
 
I have a couple of oneway faceplates that were purchased in the last year or two. Like Kevin, neither of mine have set screws. Interestingly, I keep them in their original box and the picture on box clearly shows a threaded set screw whole on both the 4" and 6" versions. I guess this a feature that has been phased out some time over the past 20 years.

what lathe spindle size do you have?? Is it the oneway M33 x 3.5? If not, where would the set screw be located on a different lathe? How would oneway know where to place the set screw for an unknown lathe with say 1 1/4 x 8? So that may be the reason the set screw is omitted.
