I find images on google confusing to post in forumd. Working niw
How do I order one?
Looking good.
Old git huh!?
Imma break a record on you! Whippersnapper!
Just came back from a caving trip in Romania and find the heat sing waiting in the mailbox so I had to cut and fix it to the light.
Copied the light dimensions:
Roughly saw it by hand:
Removed unneeded ribs to create place for nuts:
Attached to light and file the edges:
Body is now completed and I still did not get the electronics from Fasttech (shipped on Dec 2nd) maybe I start working on the rear battery case
The heat sink looks really cool.
Any pictures of the caving trip?
Wait till 2000 Lm will be connect to it....
I will get some pictures soon but not sure it is the right forum
Looks like you’ve nearly finished the host. Great work
Today I made the helmet mount from a 1.5 mm aluminum:
After cutting it to proper dimensions, I had to curve it so it will sit properly on the helmet:
Luckily a 18650 cell came out very handy to draw the 2 half circles at the ends:
To fold it precisely, I made small cuts at two sides of the Aluminum:
Unfortunately, I forgot about the cable gland when designing this mount so I had to file it a bit in order to allow a better pitching range :(
Lots of members here have posted up there caving pictures. Personally I find them fascinating.
Your light is coming along nicely. What thread did your gland have? After a couple of small ones myself.
This gland is shitty chinese one with no standard thread.
If you need small one I recommend the mini Lapp Kabel, Ip68 with standard metric thread.
I have used the M8 one for previous project and it is perfect for 2*0.75^2 cable.

Thanks for the link YuvalS. I did not think to look on Flea Bay.
While waiting to get the electronics I ordered from Fasttech (I am getting a bit worried that I won't get it in time to finish the light till the end of the month ) I decided to build the battery case:
I first saw the body from a thick cutting board, making a tight space for a double 18650 battery holder:
Then drilled holes for the screws and cable and file the battery holder to make some space for the wires:
I cut the rear and front covers from 2 mm Perspex:
And had to sand it:
After a lot of sanding:
Sanding can be a drag; sometimes it seems to take forever. Looking good. I hope you get the parts needed soon.
Continuing with the battery box, today I soldered and glued the cable
First I wanted to easily identify the right polarity for the batteries even while changing batteries in the cave using the spare light:
So I painted half of the battery holder in red to mark the positive side :)
Then I soldered the cable (2P1S):
And last thing for today, glue the cable and seal the hole:
I had to glue it instead of using a cable gland since the hole is very close to the edge in order to allow the wires to enter the case below the battery holder.
I used shoe goo because is is perfect for this purpose: bond good to plastics, elastic and waterproof
Now I have to wait for the glue to cure...
The holders are looking good.
Today was waterproofing day....
I cut rubber seals for the battery box:
And for th head unit:
And glued everything
So again I have to wait for it to cure....
The next step (unless I finally get the electronics package) Is my patent how to secure the screws so I don't lose them while changing batteries, not sure if I can explain it in pictures maybe I shoot a short video
Always nice to see your progress.
I see you have a long weight.
