Help!

i know what i want to do, i just don't know the proper dimensions...

im looking to make a mechanical 18650 with 501 connector tube mod from hand-lathed wood...

what i need to know, are the dimensions of :

Battery Compartment

Switch hole

501 connector hole

basically im going for something like this: Wooden Drip Sticks

but, i know i can make it myself, so why not?

I can tell you that the dimensions are 18mm wide x 65mm long the 18650, the 0 is because it is cylindrical. As for the switch I couldn't tell you, depends on your choice of switch. The 501? I have no idea.. If you mean "510" then it is 11/32 for a nice tight fit.

The batt dimensions are just the battery. you would most likely need to make it a hair longer.

Inner hole should be around .70 to .75 inches wide, and 2 3/4 inches long

here's kinda what im going for... the main things i don't know are the connections for the mechanical switch... and the labeled ???? stuff...


sorry if it's sloppy, i drew it up in paint in about 10 minutes lol.

The only thing im worried about with the bottom im wanting to do, is the spring for the battery, i may have to flip the spring and the other contact so i can slide on the beveled door.

I would prefer a flat spring for sliding door. Also if you use wooden body, you can meet the wiring problem - wood is not conductive. Maybe better to use a soldered to a wire spring insert which is separate from the door? Or use spring for positive contact.

With regards to the battery dimension, a protected 18650 is on average 67mm long counting the pcb on the end. A 20mm hole is quite spacious. If it is just the battery, a 19mm (3/4") hole is still loose. You do need to run a wire from the bottom, I would suggest an additional channel or groove for this so that there isn't friction on the wire from inserting the battery. If your battery has the positive side down, the vents on the battery could match vents in the sliding door.

As for the unknowns, You need an electrical connection from the battery to the switch, and the switch to the connector.

Best of luck!

thanks for the correction on the length asdaq. I just went by the standard. I am sure the space will end up being longer than either length anyhow.

Good luck with the build!

asdaq completed the needed design. Nothing to add. In any way always try to leave more space for battery, mostly in length and a little in diameter. Easier to put a spacer than to rebuild the whole body later.
