I am swaping out the module in a cheap ebay laser housing (the black heavy one most commonly found on ebay) and ran into a situation; First I had a 'rough' time getting the original brass module out and had to punch it finally...The 12mm module Im putting in seems to fit loose in the housing - isnt this supposed to be a tight fit for the '+' connection? What am I missing here????:thinking:

If the brass module is not contacting the case then the laser won't work well or at all.

easy way - You should probably get some thermal conducting glue and glue it in place.

hard way - You should get a "sleeve" that the module fits tight in while also fitting tightly into the housing. You would need to measure the outer diameter of the module and the inner diameter of the housing. You would need to find or machine a tube or sleeve that has an inner diameter that matches the module and an outer diameter that matches the housing. This might not be possible depending on how much space we are talking about. Pics would defiantly help.

IMHO the easy way would work better unless the gap is huge.

Pics!!

Thanks Pontiacg5.....Im thinking this gap may be more than desired...I appologize for lack of pics at the moment (no cam). Was just trying to utilize the on-hand cheap host with new DX module and it wasn't a direct drop-in fit....Will definitely be looking at some of the kits here to quench my newly desired thirst for a handheld laser :thanks:

Just found and realized the new module is 11.9mm and I believe the housing is 12.0mm....this is definitely loosy-loose...I'll tinker and see if I can make it work.....

Just wrap the module with aluminum foil. One wrap should do it, but you can wrap it more than once. Once you have it in place, place a single drop of CA on the top edge where the module comes together with the housing.

Peace,
