Gingery injection molding attachment for a drill press (making of)

[richardarichter123]

does it heat up the plastic so it can be injected into the mold

[scorch1974]

@richardarichter123 Yes, two of the holes in the injection cylinder block are for cartridge heaters which are hooked up to a temperature controller. You can find a couple of videos of the injection molder in action on my YouTube channel page.

@scorch1974 is the melting plastic stink or bad fumes in the air

[scorch1974]

@richardarichter123 The short answer is yes it smells. It is not terrible but I wouldn't do molding inside of my house. (I have it in the garage) Recently I built a box around my molder and have it power vented to the outside.

@scorch1974 how is it with the power vent used used fiberglass rthat stuff is pretty bad,thinking doing some molding

thanks

[scorch1974]

@richardarichter123 With the power vent the fumes are not an issue. It doesn't take much to get rid of them. I used a cooling fan from an old microwave oven and some standard 5 inch ducting to blow the fumes out the door. My vent setup is shown in my "Pen Cap Connector Injection Molding (complex mold)" video.

@scorch1974 ok thanks alot for the feedback

Nice work. I'm starting a web fund raiser for people to pitch in and buy you a used SB hand wheel for your tail stock.

[scorch1974]

@gwheyduke Your comment made my day. You are right that blob of aluminum is really sad looking.

[gwheyduke]

@scorch1974 Glad you liked it. I talked to a friend in NC who has a neighbor building a home made mill using castings from a small furnace (Gingery type). I guess quite a few of these lathes have been built. I have the book "little Bertha" and have already built and used my furnace quite a bit. Enjoyed your video.

nice video, I liked the video edition, short but concise as well as the music you used.

on a separate topic how long did it take you to make the lathe?

cheers.

[scorch1974]

@juanoporras Thanks. It took me about 5 years to get my lathe this far. I have worked on a lot of other projects during that time so it was five years part time. It is still not complete. (there will probably always be something to improve on it.)
