Tree Billy could rig something with this part, $5 not bad for test.
Household Essentials Aluminum Clothesline Spreader - Pulleys - Amazon.com
There was a lot of clothes line pulleys in search.
Time for some water tests and different lines.
If Treebilly has access to down-rigger just use the SS cable in it. Have his boat hand operate it. Might be a cheap test, just cost him a six-pack or two.
LOL,
My roots go into the design of equipment that is 100% Automated making Vacuum deposited thin films. Some of the projects I've worked on are in different country and can be run thru web link.
Thin Films e.g. ( night vision goggles, Optical weapons, or the films on the space shuttle windows)
Get a room full of engineers and a big budget and task , you be surprised the crazy ideas that will come out. Always been surpriised at the end when it actually works. I've scared a few bosses when I say that in post project reviews and we burned up all his cash. <img src= " class="smiley" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x" height="23" width="23" loading="eager" data-tooltip="biggrin" aria-label="biggrin">
Lots of Good ideas here.
What about a plastic pulley on the float, Thinking of those cheap pulleys used for clothes lines. I think those are like 4 - 6 inch Diameter. Might be a stronger pulley on market, have not googled it.
This could get the lines apart with less tangles and give you better feel for adjusting weight balance. I think I would play with it in like 30 foot of water and have buddy in boat doing the work while your in water watching it.
Pulley spinning could give you feel for speed vs adding markets to the line.
Line weight on both sides of pulley and it's change makes it more interesting. I see it moving slower in the beginning and then it would go faster as it got to the top. Might be a positive feature.
If you wanted to get real fancy - spancy, you could over weight the one side and add some type of drag/friction feature to the pulley.
IF you really wanted to go over the TOP, you could have whole setup on a reel that had a small gear motor, Drops line to bottom, ( detect no tension) stops, reel up at set speed, detect flasher at top, maybe a pause so you have chance to shoot fish, then it lowers weight again to bottom. I would call this a Full auto version. Kinda look like an electric Down-rigger.
There are minimum size limits on most fish in the sea, but no bag limits or fishing licenses required. Foreigners can fish/spear as much as they like, but it is illegal for foreigners to sell fish (residents can sell fish up to a certain limit) or bring more than 20 kg fillets (or maybe 15) + a whole trophy fish out of the country. No spearing in fresh water, except pike (for some strange reason). All anadromous salmonids are illegal to spear in the sea (charr, salmon, trout) as well as eel. Lobster are off limits for divers all year; short pot fishing season in the fall.
Sounds like fair and well thought out regs. Not used to that here in California. At some point a diver will need an attorney with them to read the regs.
ASIDE: Shooting Pike, Just for reference, If you are in Montana , USA, there are certain areas where Northern Pike are on the Kill list. Looks like they are in the wrong areas by accident and messing up normal life cycles. Other Northern states in USA might have similar options. Verify first with fish and feather Depts.
Nice video, Looks like a fun place to go diving. I like the cold water, from just being used to it. Keeps your dead fish cold too.
Warm water is nice, just feels weird to me.
How are fishing regulations from governing body?
That fish is called a wolffish shot near Russian border near a place called Kirkenes in Norway.
I can hook you up with a diver there. Having a local would be my choice.
PM me your contact info and I can send it to him. He was just in Bahamas, guessing he will back there soon.
Here is some crazy fish he shoots up there
You might need to groove the wood a little, or have him leave a feature on back side to fit the existing notch in the wood. or maybe a spacer for slot in wood.
Depending on your tool capacity and motivation....
Measure good so he can get holes to line up.
But doesn't take a powerhead.
C'mon countersink screws would be plenty strong for this application, this ain't a bayonet.
The wood threads getting stripped out would come first I would think. Countersink would require extra tool, so less time to make would draw me to button head.
I still like a hole in the front and a sharpened rod in there. That's real easy.
------------------------------- 7-23-14---Below ----------------------------------------
I stand corrected, you can do the drill and countersink with one tool. Another tool to buy.
I was in chat with Wood-guy.
316L SS and 3/16" thick. More strength with button head screws over Countersinks I mentioned earlier.
I was thinking it was 1/4" flat stock.
I like the Flat point better than the round version, easier to make. 
George, Hole doesn't have to be too big, could be smaller than the shank of the spike. but good point, it shouldn't need too much strength. 1-2 or 1-3 ratio for diameter / depth should be good enough.
The hole could aide in a crack as well. maybe...
It's nice to have different options to choose between.
Interesting design. I like Dan's concept of a hole in the front for spike, doesn't look like enough depth on that speargun.
Not to be picky but a countersink screw over a buttonhead might look a little cleaner.
Those look like carbon steel of some sort.
Correct on the Visible light dropping out red first as the sunlight goes thru the water.
(ROYGBIV) visible spectrum. aka rainbow with refracted light on water vapor.
Fish see in the UV spectrum better than we do. the violet color is color band closest to UV.
Dan take a look at your colors with a black light and see how they look, Poor man's way to look at reflection of lower Visible spectrum. Might help in color choices.
Deep sea fishing lures design around enhanced UV reflection. Gimmick or not but it's out there, BTW.
Dittos on welcome.
Post some pictures of the area. Everyone would love to see them.
This is my favorite forum, great dialog on what everyone is doing.
It's a great source for gathering information and getting honest comments without alternate agendas going on.
I love the threads where we have different views. Great respect in point counterpoint interactions with folks NOT getting their underwear in a wad.
Some one must have a story about not putting in the Plug. Not me on that one.
Had motor go out on my Brother's 33 foot sailboat in Puget Sound. We sailed it into to port and landed right in front of some restaurant with everyone watching. I remember all the large windows and everyone staring at us.
We were about 20-30 yards from our target and wind just died. I jumped off the boat and managed it from dock while the bro dropped the remaining part of the sail. We also were lucky to have a wide open area to land on the outer portion of pier.
All said and done we looked pretty good on not tearing anything up, and looking like we knew what we were doing. I think we got really lucky with wind dropping off.
On the dock and catching our breath, wind was back up some. Can't recall where that was at, might have been Everett or Anacortes.
The large dinner audience watching us probably had some stories to tell about two idiots sailing into port. Non sailboat types probably thought that's how you do it.
--------------------------
Did Google maps search, Looks like it was Everett, restaurant name was Antony's homeport right on the water. It has long pier out front of it, has to be the place.
Yep lots of extra anchor line, and setting it important. It's nice to have the reminder and you being humble about experience.
I like swimming down to the anchor and have a look at it if it's not to deep.
Got a nice spot that is too deep and too much current to free dive. Got a saddle on a pinnacle that sits about 30 foot. We get the anchor in the saddle and then go down the line to verify the setting and do our dive, then back up the anchor to the boat.
Anyway, had a 16 year old boat driver so post dive we can just surface and flag for taxi ride. We screwed up and assumed driver knew how to free the anchor. Line was at say a 60 degree angle and decided to just pull it up. he couldn't do it and was in panic as we were floating out to see.
Took us 5 seconds to realize we need to do Plan B. I got all the gear ( guns, fish weight belts, BC/tanks in a tangled mess and continued to float HI.
My Buddy a lumberjack swam into the current and to the boat. Showed him how to use the engine to free the anchor. The Driver should have just cut the line and came for us. anchors are cheap.
Anyway we failed to verify his skills and assumed. Got a clip on anchor line now and a gallon float jug for solution in future. Never needed new setup yet, but could use anchor and float to mark a spot if we needed to.
I sure didn't like the 15 min wait with all that dead fish on me as I waited for pickup.
Was a humbling experience, but we did react properly with Plan B. Plan C would be for me to dump all the gear and swim at an angle to current for shore.
Nice lings. I have yet to get one of those with a spear. I will have to try when abalone season opens again.
You can still hunt Lings in July. Going to try to dive on Wednesday in Fort Bragg, watching water conditions.
I looked up your location, Long drive up here.
Vis looks pretty dam good compared to what I get. Also flat water and no surf/swell. You must be in behind an island or two or more.
Video looks pretty good,
lol, I was told it wouldn't work on other forum.
Stole concept from a different job where we had snap on covers for protecting some bearings. It was my buddies concept, I just used it on the cover after some geometry was done. He is one of the guys that worked on that Titanic model I posted a while ago.
There is a small radial groove on the tip shaft. inside the cap there is a deep grooved groove with a Stainless ring in it. this ring is short of a full circle. slide cap on tip and it expands the ring then it "snaps" into the small groove to hold on.
Pretty trick attachment.
Funny thing is you have them in your gear. All of those swivels, that's what is inside them. Only difference is the groove is deeper and a square slot. Once it snaps in, you can't get it off. The rating on those is based on the force to shear off the small ring in the two slots.
George will lose that one in no time. The next one I think I will add a couple holes in the front at an angle so water can pass thru it for reduced drag while keeping the OD of the cap.
