Label protector for steam cleaning on VPI 16.5?

Has anyone come up with an effective device for protecting record labels when steam cleaning directly on a VPI 16.5? I have seen the GrooveMaster and other similar devices (dent pullers)which appear to be better suited for hand washing. I want to be able to apply steam while record is rotating on RCM platter. Device should be able to fit under thraded knob which comes with 16.5. Thank-you for your help.
Try using one of those soft silicone round thingies used for taking stubborn jar lids off. You can put a hole in the center to fit over the spindle. Put record clamp over that.
Problem solved!

P.S.(You can make your own from pure silicone caulk found at hardware store. You just need to make a template for the size you want like the lid from a mayonnaise jar.)

Happy Holidays!!!!
I have the perfect solution for this, I have been using this for years. Please don't laugh, I use the round top from Chinese food container or the ones you get from the deli. I drill a hole in the center of the container top and install it top side down towards the record album. It covers the label perfectly. The round rim on the top side of the lid forms a nice tight seal to protect the label from the steam and you are still able to use the threaded knob for the 16.5. I will put some duct tape over the hole to make the top a little more durable. It will prevent the top from splitting. You will be able to crank down on the threaded knob so that the record album doesn't slip when you turn the vaccum to remove the moisture from the album.

Cheap and it works great!!!
TTWeights sells exactly wat you are looking for
Actually that won't work. It is 3.45" in diameter so as not to interfere with the wand of the 16.5. A record label is 4" min diameter. It would not cover the label completely. Basically, what TT sells is a high-end clamp to replace the cheap plastic threaded one that comes with the 16.5. Good thought anyway.
