CC injector in BT molds?

[fish_4_all]

Well I got my molds today, sorry Jason, they are from basstackle, I have to wait til we can work on the egg molds. I have an injector but it will not work with the molds. I guess it was special made with a cone end for cone cut mold injection sites.

So I need to get another injector before I can even try these out. Will the 4 ounce work with Basstackle molds?

I did watch the video on using the injectors but I must have missed how to be special careful with the 4 ounce because it has no locking pin. Can someone please enlighten me on how to keep it from coming of when not wanted. And is this a real negative issue with the 4 ounce or is it just more of be careful and slow to keep it form coming off unexpectedly?

Place you gloved finger on the nozzle when purging the injector to keep it in place.

I have some molds from other makers and have used CCM injector with all of them, with out any issues. As far as purging the injector you can do as Kipbass stated, I use a metal skewer and that prevents the tip from dropping off while allowing any melted plastic to flow out.

That injector is from Jacob's I would guess. I do believe he makes an adapter. All the other injectors I have dealt with are universal to all molds.

Had an injector where the tip popped off once, put a set screw in as I never felt comfortable with it and 350 degree plastic.

I am thinking that a locking pin is going to be a big issue. I have a 12 and 11 year old son and I don't want the accidental ejection of 4 ounces of hot plastic when they help me. 9.5 ounces to get a locking injector is a lot for me being I don't plan on, right now anyway, making more than a couple hundred injections a year.

I think BT makes a smaller injector with locking pins.  The only bad thing about it and ours (9.5 oz) is that the tubes are thicker to support the locking pins.  This requires additional attention to keeping your injector warm or you are going to have a challenge with your plastic setting up inside the injector.  It's something you can master without a ton of effort, you just need to be aware of it.

Why not something as simple as a spring loaded retaining pin type setup? Secure a flat piece of metal to the nozzle putting a small pin on the tube that the flat metal locks into? Would make removal easy and secure the nozzle without having to make the tubes thicker. Could even machine the tube, if you machine them, with a small ridge instead of adding a pin.

I will see what I can draw up and send it to you so you can see the idea.

You can put a "stop" on the rod of plunger so that plunger (inside part) does not come down far enough to push the tip off.

 If you are mechanically un-inclined, such as myself, you can do it with some wraps of duck tape....or if you are daring (and able) drill a small hole through the rod and insert a cotter pin (which I eventually had done in the shop at work on the drill press).

An even better way (unfortunately I didn't think of it until AFTER I drilled the hold in the rod ! )  is to take the plunger to the hardware store and buy a DRILL STOP that fits the rod ( if the little black knob on the end screws off).
