I'm just in the process of designing a can light.
Helpfully I live really close to troutie so I'm going to go see him and buy some ahorton aspherics.
I'm planning to put an XML behind, with an SKU 127684 5 mode 2800mA driver. Though, I only want a single mode (on!), so I'm going to order a few and try and bodge it so it's simply on and off. Has anyone got any experience of these? I don't want something that's going to be a pain and accidentally drop onto SOS mode or something daft!
No quite finalised how I'm going to do the body yet, I have a lathe but my screwcutting is a little dodgy so I'm trying to keep that to a minimum, also I'm limited on depth of boring so I don't want any fine features at the bottom of a deep hole. I'm thinking of using tubing for a lot of it. I'll stick some drawings up in due course
I have a few questions for anyone who knows, hopefully not too ignorant sounding.
Is there good reason not to use the body of the torch as electrical contact? I'd be relying on a threaded fit between body and tailcap for conductivity, all aluminium.
Looking at greenforce cable, they use a fancy plug with copper contacts for -ve and +ve.
Cable glands; I've seen these
Which look nice, and should be strong, but am I going to give myself a big corrosion headache putting nickel plated brass into aluminium?
Also sealing the glands, I thought to cut a fairly tight thread, and use some loctite 542 or similar thread sealant. Is this the done thing or do you add an O-ring/dowty seal?
I'm yet to design the canister properly or choose a cable but thinking of 3S3P NiMH C cells, if it will be small enough.
