Not entirely sure if I will mill all the way through, but I think it would be better to just mill a pocket and use a cover on the top. 125 piece so it will fit over the spindle, when not using the collet chuck. ~2.500" on diameter of collet nut and the top register of the taper. Ironically, these are almost exactly the same size. Here is the spindle nose and collet chuck. The small pieces are scarce at SIMS so I grabbed those thin pieces, and a piece of 3/8" plate and a 4" round. A friend took this piece last night and is cutting it in half, and I will use a 1" x 4" x 6" piece for the frame portion. SIMS charges the same for 7075 as they do 6061, but unfortunately didn't have much 7075. A friend took it last night and is going to cut it on his band saw to 1" thick, which I plan to use for the frame portion. The piece I was mostly after is the 2" thick, 4"圆" 7075 T6. Went over to SIMS yesterday, being the bottom feeder I am.I picked up these pieces of aluminum. If the jig fits over the tool, you can use the same tool without having to retool for each centering. I think the shape has a bit to do with it, and am planning to copy Dan's design in the video kinda sorta.there have been a number of jigs that have a shank and fit into a collet, but the problem with that style is you need to retool to use the jig. If you google you'll find others that people have made, some with mixed results, some good. Here's Dan's patent, in case you haven't seen it. I will also use a mini-toggle or similar instead of the momentary switch in the kit.
I'm going to replace the 2 x AAA batteries with a smaller watch battery, so will get a small holder to replace the one in the kit. rectangular design, and it seems the reason Dan's uses a rectangular design is to get space for the laser and batteries itself. On the ER40 chuck, it would slip over the outer diameter of the collet nut, and have a small step to register on the face of the nut itself.Īlso thought about circular vs. and use magnets to secure it to the spindle. There is a small area, that i think I can turn a thin ring that could register on that area at the top of the taper. I'm pondering a design that could be used for both the ER40 collet nut, as well as the vertical head spindle, which is almost exactly the same size at the top of the taper on the spindle nose. I have ordered this DIY laser ponter kit, to use for mine.ĭIY Red Laser
