Completed the head for this light last night. (Body is a Tain TixDa body (1 of 20))
Made from two small pieces of stock (Ti and Del Ealy Damascus.
threaded the Ti to E-series head threads all the way through, then threaded a short section of the Ti for external threads, then matched the Damascus to those threads, with a super tight fit. had to use pliers to get the two pieces fully seated, so they will not ever come apart. Cut to length and then finished the outside down to size. I think it goes well with the Tain Ti/Damascus Body...
