Thank you for having taken the lead and started this business and made it possible and straightforward to buy components for the laser hobby. You really are one of a kind in the USA. Your customer service is excellent and so are your products.
While I do understand that you're a small operation, I hope that you guys find a way to improve your ship times some time in the future.
Cheers! and thank you!

hello. great site with really good stuff!
About the S4X 20mm adapter:
1) do you have a 25mm? I notice DTR has the 7W 450nm emitter mounted in 25mm copper but not 20mm.
2) is there enough meat on the inside of your 20mm adapter to lathe it out to 25mm?
3) do you provide the above lathe work?
4) is your driver heat sink pill intended to fit inside the DTR module copper back half driver cavity? (with driver mounted on the pill shelf ?) or will it fit inside the DTR hollow aluminum back half cavity?

thank you for all you do for the laserpointer community!

Hi cncyana, thanks for the comments and sorry for the late reply. We don't currently offer a 25mm adapter for the S4X host, however at your suggestion I tried one of DTR's 25mm all copper modules and it looks like it will indeed fit if the I.D. of the adapter is bored out. In fact it barely clears the threads. We don't provide individual lathe work but I may get a batch of 100 or so modified to fit. You can also purchase a 20mm adapter and ask a local shop to machine it out to leave about 0.005" diameter clearance around the module and you should be good to go. The driver heat sink pill will only fit those modules that have a 12mm or larger bore in the back half. If the back half is bored out then it should fit. The diode module will basically butt up against the pill module when the assembly is fully threaded together. I hope this helps!

Excellent Gary, thank you for your explanation and pictures! Looks like an easy mod to accomodate the larger 25mm DTR copper heatsink !

Question: How many amps will the tail switch in the S4X handle? Thank you for your help!
