How do you make the barbs on your spears? You should post some pictures of your spears here for the guys to see.

I don't have pictures of the actual spear making process. I will have to take some and post them as I do the next spears. Here are a few pictures of the spears presently.

This is a picture of the heavy weight spear head before finishing. The brazing in the barbs does not show up very well in the "white" condition.

This is a standard weight spear (6.5 lbs). The brazed barbs can be seen.

Here are the heavy (8lbs 3oz) and the standard spears. The heavy weight has a knurled copper grip section. The glare prevents a good view of the brazed barbs. These are both spears that I have used all year so they show some wear and are not as polished as when they are new. It is easy to touch up the finish at the end of the season. I will post some additional pictures of spears in progress in a week or so.

I'm in the middle of a spear build with square tines and brass barbs.

I use a 4 1/2 inch angle grinder with a 1/16 inch width cutting wheel first to get the rough shape, then a coarse grinding disc, then a coarse sanding disc, then I heat treat and temper, then I use a dremel tool with a fiberglass cutting disc to clean out behind the barbs, then I remove the decarb and polish with a fine Norton polishing disc. I never said it was quick.

Well, I finally have a couple pictures that should show how the tines and barbs are made.

spearlayout.jpg

This shows the layout of the pieces before the barb pieces are brazed or welded to the tines. Then they are shaped as I described above.

heattreatingspeartines-1.jpg

This shows the tines with the shaped barbs starting to heat up in the heat treating oven. When they reach the prooper temp for the right amount of time they are quenched and then spring tempered. After tempering, they are sanded and polished and finished.

Nice. How did you learn the skill omaking spears? Are you a metal worker by trade?

No, I'm a research biologist by trade. I've been spearing and trying to improve spears since I was a kid. I'm 57 now, so that's a fair amount of spear trial and error. I used to spear in Lake Michigan in 20+ foot of water and was always frustrated by my spear planing or the difficult aspect of trying to compensate for the optical diffraction problems on angle shots. I enjoy metal work, so this seemed like a good use of that information. The proper heat treating aspect of steel work is what I really find interesting. Thanks for the interest.

Well, it's programmable up to 2000 degrees F, so I hope you like your crust extra crispy.

      2025 Mn bear....

      By smurfy · Posted

      application has been submitted. 👍   Leech......i've shot my share of bear......it be nice to get another but not the end of the world if i dont. i get to spend time with my son...its just another way to get into the woods. i've been at it since about 1976......that rush when you walk up to the bait and see the logs scattered all over and bait gone just doesnt get old for me.   i had to get rid of 1 rug because of bad tanning. i have another rug, shoulder mount and made 3 pillows from 2 different bear hides. my biggest issue has become what to do with the hide....that seems more of a trophy then the meat. i inquired 1 year at the Alex decoy show when there were a couple hide guys there and they didnt seem to interested. 🙄 i have no other ideas for the hide.......approval from the wife is not even negotiable!!!!!

      Something in May, like around Opener.  Could be white knuckles for boaters that weekend with the way things stalled out since the contest started and how thick it still is.   Highs in the 50’s coming but lows are around freezing and not a lot of wind in the extended forecast.   I’ll tell  ya what, if you change from 4/26 and it hits that date, I’ll buy ya some mythical FM beer.  And you know where you can find it. 😉. But don’t change on my account - this is still a free country!

      I caught the 10pm news the other night. They said that starting next week Minnesota will be above average for temps. I give them a 33% chance of getting that right.
