I build will be building a light based on a section of scuba tank. I sure hope the scuba tank is smooth and of consistent diameter inside. K50 and oxygen tank are in pictures for scale.
Went from air conditioned house out into warm humid air. Had no cells in the K50 to burn off the fog.
The tank is 7.25"/184mm OD (Will be less after removing finish). I may be shooting for something like the below diagram, nut will likely have to scale back to bring down weight. The idea is to have the following available on one side:
Supper thrower with Dedomed XP-L
Floody thrower with Dedomed MT-G2
Flood light with XHP-70
The other side will have the following separately available:
UV lights
Red lights
Blue lights
Old high CRI Nichia 219's (Neutral to warmish)
Newer high CRI Nichia 219's (Neutral to coolish)
The light will have lots of light options, good run times, and capable of fairly high output. Disadvantage will likely be weight and size. Will probably need a shoulder sling to carry for medium/long periods of time.
Proportions are all out of whack in the picture below. There will be as little space in the center as possible. I need to make the light as short as possible and remove as much excess material as possible to bring down the weight. Will be 3P (not 4P like in the picture) cells in the 4 banks. The cell tubes only be open to the outside. If a cell vents, it will blow a relatively weak plug to the outside.
Heat pipes can move heat up to like 250 times more efficiently than just copper (I think I read that some where).
To cut it as straight as possible with a sawzall, you should continually rotate the tank to cut a channel all the way around. Keep rotating until the channel is almost through the tank all the way around. Then, finish cutting through it straight down. The channel you’ve made will keep the blade relatively straight.
Thanks guys. I decided to go with the scuba tank and chose overall design. OP updated. I probably won't get a chance to start working on the build till Sunday.
^ I think there are many that would agree with your assessment of my mental state, but the voices in my head disagree.
It is a bit crazy in that I'm not sure how I will be handling and machining this behemoth.
Speaking of machining. I'm taking this opportunity while the judges reassess the rules to request that my entry be reclassified to the Machine Made category. I've renamed the thread as I'm sure the judges will accommodate the request given the circumstances.
EDIT: Seriously though, I really have no chance of placing once another talented member joins the category. I like trying though because it challenges me and makes me grow.
Changing to Machine Made should be easy - they just move your name. There shouldn’t be any major decision to be made. It’s not like you’re trying to move the other way. Hand Made is the more restricted category. :bigsmile:
