Re: SKOGSTA, the Ikea speargun…1st build, few tools—

Next I drilled the holes for the pins of the mech. That was by far the most difficult since all I have is a hand held drill.
I briefly contemplated trying to build some sort of a jig to get closer to a drill press but just couldn't come up with any idea reasonably effective (ie a few hours vs days of work) so I just had to wing this one even more than the rest...

To do this I placed the mech on the side of the blank and tried to get exactly where it would be if it were in the mech hole I had made.
Then I marked the holes on the blank.

Then I drilled as straight as I could...I used drill bits slightly smaller than the pin size thinking it might give me a chance to course correct slighty by enlarging them manually

Next I addressed those unsightly screws. I had a very thin strip of wood from when I had adjusted the handle angle and made from it 6 circular shapes to cover the screws

I would just cut a square roughly the right size and then shape a circle out of it on the sand paper I had

More more more!!

Loving this DIY stuff!!

I dooooo get a horrible feeling though that the thing will implode in your hands / face when loaded up though, the wood itself doesn't scream "high quality" or "strong"..

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

Next I started building the trigger guard. Again wanting to keep things low tech the idea was to use a spoon (Ikea spoon of course to stay in the spirit...)
but because I had glued the screws and they were now in the way I couldn't recess the spoon, er, trigger guard correctly.

So the ugly fix I had to come up with was to cut the spoon and then use the spoon head as a plate keeping in the place the spoon handle

This I would definitely not do the same next time, I would recess it more. Another option would have been to bend the spoon around a circular shape and then fix it to the forend first and then fix everything to the rest of the gun

Still in full Ikea mode I decided to use of those thingies to hold shelves to help wrap the line around the shaft

However when I was actually testing the rigging I realized it was very impractical, probably because I positioned it too low so I ended up removing it and filling up the hole with epoxy.

Hi Willstroo!
Glad someone is liking it :-) I was beginning to feel a little lonely here haha!
So far so good... I have tried the gun in and outside of water by now but not on fish yet... Although the wood is acacia, since it's already laminated it's pretty strong and the added element (sort of what would maybe be could the foreend on a shotgun I guess) really adds to the strength.

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

This is how I ended up doing the line guide. Rummaging around I found a metal bracket and cut off a piece (with a file, I don't have a saw that can cut metal)
file it to give it a rounded shape on the external side and screwed it in place

Cant wait to see the gun with rubbers and rigged, slaying some fish with this would be SOOOO satisfying!!

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

Next I started doing the part I was most reluctant to do, ie insert the mech and the pins. I was really worried about how that would work out. One of the pins actually went in fine but the other one was a hole (pun intended...) different story...

I was probably off by 1/16 or 1/32 of an inch but that is a huge when trying to drive a pin through 2 mech holes and 2 wooden holes so I spent a lot of time filing the hole with a small file and then push the pin through. When I saw I had got past the 2 mech holes I hammered it in and it pushed some wood on its way but I couldn't do much about that at that point

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

Oh yes, I nearly forgot to most painful part yet. Since the wood I have is not teak I'm supposed to seal it entirely.
However my concern was that if I sealed the mech pocket the thickness of the epoxy would prevent me from then fitting the mech itself once the epoxy had cured.
Now matter how much I researched online I wasn't able to figure the thickness of 2-3 coats of epoxy (if only I could have asked all these questions during the build!!) so I made a terrible decision which was to seal the pocket and then I put the mech in place before the epoxy cured.
That probably helped fill any irregularities in the pocket but it also had one disastrous outcome which was that some epoxy dripped on the mech and the trigger now really struggles to come back to its original place once pressed.
So if you're reading this don't do it

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

Next I started coating the band holes and my line anchor system and lanyard hole.
You can see on one of the pictures how I made a slight groove to guide the line towards the line release.

Also, don't know if these tips are any good but this is how I did to have more to work with than just brushes. When I had to coat small holes I dabbed some epoxy on spectra and then pulled the line through the hole a few times.
I also let a few pieces of spectra harden with a weight (pair of scissors in the case of the picture) so that they would be nice and straight and use them as micro paintbrushes for finishing touches here and there.

I also used an old juice pack to cut out strips of cardboard. This cardboard is lined with a plastic lining so it has a bit of flex and works really well as scrapers. My 2 cents, I'm sure there are tons of others ways to do this.

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

Then I put together a jig to facilitate the epoxy coating part. I had a few pieces of scrap plywood so did something that would enable me to hang the speargun upright.
In retrospective I would have added some way of fixing the speargun at the muzzle end through the band holes since it had too many degrees of freedoms this way, but then again most posts covering the epoxy topic just say hang the gun so maybe I'm doing something wrong.

The last picture is with one side with it's first coat.

Re: SKOGSTA, the Ikea speargun…1st build, few tools—

This is a picture of the gun after 3 coats I believe.

A closer view would reveal a ton of defects. One thing in my defense is that I was getting paranoid about inhaling uncured epoxy dust. I don't have a respirator and even if I had one I am working either in the bathroom or the garage and have kids running around all the time so I decided I just would do zero epoxy sanding.

I let the first coat cure (not a good idea, but had to stop at that point) and then made sure to put all the layers in sequence when the previous one was still tacky to get a chemical bond rather than mechanical and avoid sanding.

Next I moved on to the buttpad. There seemed to be a global consensus that flip flops make very decent buttpads, so I sacrificed my only pair in the name of science...
I had a little repair kit for neoprene suits which was perfect for gluing it so that got me one step closer to the finished product...
