These i use for threaded handles. I haven't tried attaching a Gomexus Knob to an existing Epixor handle that isn't threaded but i've already did this- My Gomexus Plug & Play "Power Handles" Will Fit my Inspira & Epixors! kzfaq.info/get/bejne/Z9apf6yQusWmhJc.html

Thank you

This is an extremely slow & expensive process. I'm only tackling the ones that the equipment is nearby & the project won't cost that much. Just to purchase what i needed for this video was $200. I like the stock knob of the 8K by the way. Big. Easy to grip when you're wet. When i purchased the Ceymar HD 5K this was the newest of all the Ceymars. And wasn't cheap. The Power Handle was $60. Plus i had the knob & the extra handle. Plus i really don't see a need for a Power Handle or Knob for that model. But i guess you do? Just to figure out the handle alone would require at least 6-8 knobs of varying sizes for closely related makes. If you tried just researching & purchasing add-ons just for 1 model, with no guarantee if it'll work or fit correctly, then you'll see what i mean. I have to absorb all my own mistakes as well. And the few bucks i earn just from 1 project won't cover the +$1,000 a month i spend doing this. A lot of what i purchase can't be returned or used if it doesn't fit correctly. I have to say this because i get a lot of request but i'm the one absorbing all the cost. Not mad or frustrated, just once in awhile i need to point this out again. Again i don't think it's needed as the original 8K is pretty good & inexpensive already. Thanks.
