Hey, you are to be commended for a job well done, first attempt or not. What sort of glue/s did you use? did you mix in some ppurpleheart dust into the glue for the v-splices? I've competed with purple heart foreshafted atlatl darts for decades and not until recently have I put on any metal field points. If you are only shooting into bvales of straw you can get by. Otherwise get some 70, 100 and 125 grain field points. Depending on the density of the species of lumberyard dowel you used for the main shaft, a 125 grtain field point may make the arrow too point heavy. I recommend a balance point of 7 to 10 percent forward of center for target shooting. Find the balance point on the finished arrow and mark it. Measure the overall length of the arrow and then measure from the nock end of the arrow to the balance point. Divide the last measurement with the overall length to give you a percentage. I call this the balance point. To get the forward of center, subtract 50 percent from your figure. You will most likely have to use a file or rasp and sandpaper instead of the pencil sharpener taper tool to get the hard purpleheart foreshaft tapered. By all means, shoot them. Enjoy the fruits of your labor. Until next time. Go to the woods. Walk softly. And carry a bent stick.
