Vapor Country sells the adapter. I ordered one last night, even though the store is 'on vacation'
through Friday the 13th - but I'm hoping I'll get it Monday or Tuesday (expecting my Xhaler and a pack of 5 cartomizers tomorrow - I'll use my 901 atomizers until I get the adapter and can try the cartomizers for the first time.
DaMulta posted the info about the adapter at Vapor Country over in the Chuck
thread, and several other 'Chuckies' chimed in with 'Yeah, that's the right one', so I'm confident it's the right one.
None of my other searches of the forum seemed to find anythng else that sounded right, with the exception of a post showing how to use a Dremel tool to drill a couple of slits in the 901 vaporizer threaded end to give the atomizer the necessary air flow with the cartomizer. Yeah, like I'd even recognize a Dremel tool if I tripped over it in my local Lowes or Home Depot. I saw the sign for one in Lowes but the shelf was empty and I think the price was something around $80 for the tool. Definitely not an item that will go on my letter to Santa!
The only power tool I'd ever
buy for that price is something that will open clamshell packaging!
