Update: Nov 8, 2006
I got some drawings back last night and would like to share it with everyone. There are two style (SW01 and Aleph). Which one do you like?
****************************************************************************************************
First of all I would like to thanks Campbell for his kindness in sending me Carley 1499 to run this prototype.
If you are running hotwire set up in BHC you will experience head wobbles with TL-3 setup. This due to head has to be turned almost to the last thread to get proper focus. To solve the problem I used regular washer and placed it in front of ceramic based. However, this is just a quick fix and wobbles still exist, but slightly less.
I noticed that Carley 1499 is even worse than TL-3 due to longer bulb and filament. Head must be turn at a point where thread has to be disengaged to get that sweet spot.
To solve this problem, I have machine shop made me a 3mm thick spacer and a new tail cap. The reason for new tail cap has to do with additional 3mm recess from the head, which rendered original tail cap useless in off mode. New tail cap solve this problem with shorter threads design and additional bulb holder in the center as original M@g tail cap (Not shown in pics but next proto will have one and o-ring also).
Testing with Carley 1499 shows that head wobbles nearly eliminated (about 95% improvement) and twisting on/off function works great. To get that sweet focusing spot, require only one full turn and should be less with TL-3 set up. The extra length added with new tail cap is not much. Judging by eye is less than 1cm.
This is setup for BHC C1499 and TL-3. I'm not sure it will work with normal head and metal reflector that comes with hotwire kit or not. I'll have to check later.
I'm sorry about my English. I have done the best I can to explain. Should you have any questions, please post here and I'll try to answer them. Thank you for looking and enjoy the show.
