i read an instructional awhile back somewhere about making tradepoints, and the method they described used the necks of spent rifle cartridges as glue on collars for the points that the blades were brazed or soldered into. anyone firmiliar with this method?

I just haft trade points directly to the shaft like I do with stone points. I use pitch glue and a sinew wrap for this.

yea thats what i normally do too(minus the pitch.yet to really try that on anything) and it works great. i was trying to find this method again just to see how well it works, its probably not something id do alot but it never hurts to learn a new skill.

i even started doing some knapping but so far havent had much luck, have alot of real small points due to breaking some and re shaping.

The brass in a rifle cartridge would make a very weak neck for a broadhead connection.  I would look for something tougher that you can use that wouldn't bend as easily.

i got some steel casings that id use to try it, i mostly wanted to know if anyone else had ever came across this method, i found it some time ago when i was doing research and wanted to be able to add it to my references. it was in an older publication but ive lost track of which one.

It would work and if you were to fill the taper on the inside of the brass cartridge and the steel head with something that gets really hard like mettalized JB weld it could be an effective method.  I am presently making up a dozen trade points in my blacksmith shop getting ready for a self bow I plan to make and some cane or ramin arrows, I will make from scratch as well.  I am thinking about deer hunting with the bow and arrows this year.

I also like to half and sinew them.Cut them from old circlar saw blades.All read tempered cut them out with a drimel and the work just fine.
 I use to be a welder for 25 years.I've brassed them in shell caseing's also.this also works good easy to remove.

im planning on hunting with my gear this year too, got some arrows in the works and got an old saw blade im cutting my points from. trying to find some river cane local or wild rose right now to provide more shafts, but i have backup if need be.finishing a fow hide back quiver to go along with the rest of my gear too, all the while im scratching out a bow for my lil sisters birthday. i like having it all goin at once so while one thing is drying, curing etc i can work on the other.lol
