    Lathe material unsupported how much?

    For this job - not at all. But if I am talking duel spindle, then at that point, I will want the Y-axis for other jobs. For now, I don't have the budget for what I want. I have to get what I can afford. I'm just not willing to take on another machine payment the month after I paid off my...

    Lathe material unsupported how much?

    @Ox Great info; thank you. It makes sense that the part of the blade can be used to chafer, etc. I will have to try it out to learn more about it. Thank you for the tips on holding the parts pryer to the full part off. Snapping them off or a quick whack with a soft-blow hammer is great. I do...

    Lathe material unsupported how much?

    I was thinking I could get away with one op. Prior to the part off, I would v grove the area the part off tool would go into so that it creates the chamfer on that backside OD edge. Then run a .200" wide part off/groove tool (no idea if they make them, but I think they would) down to the...

    Lathe material unsupported how much?

    My non-lathe brain was thinking I would accumulate the 2" spuds, then hand load them holding .75" in dedicated soft jaws, cut one face feature, hand flip cut the other face feature, then run a wide grove in the middle to make the boss, then part off. = two parts. I agree. If I can find an...

    Lathe material unsupported how much?

    That's good to hear. It seems like it would work, but my material is usually not the part spinning in all the milling I have done. Ox, I would not run the material out the back of the lathe but inside the work envelope. Hold 2" deep with the jaws, then have 6" into the work envelope to machine...

    Lathe material unsupported how much?

    Good point the 7.8oz finished part would knock about a bit. Padding makes sense.

    Lathe material unsupported how much?

    I would love to get a dual spindle Y-axis lathe. But in our current economy, I need to keep the acquisition cost as cash upfront, so it limits me to $30k ish tops. I need to make whatever I get work for a while and let our economy come back some before I take on another machine tool payment. I...

    Lathe material unsupported how much?

    I'm not a lathe guy at all. How far out unsupported can I run a 3" bar of 6061 cutting simple features? The part is 3" OD x 0.75" thick, with a .075" boss on the back with the front having a radiused OD edge with a chamfered center hole. Simple less than an inch thick part. Asking as I run...

    Deep hole threading? 2x one shot or peck tap?

    I originally thought to thread mill but most of the thread mills I see are 1.25” in length. With that 1.5” material I would probably have to go to a 3x the cost longer reach tool. So set up the first run to use the spiral flute taps.

    Deep hole threading? 2x one shot or peck tap?

    Yes through holes. Good point on the chips with speed. They will be some long stringy things for sure. Thank you.

    Deep hole threading? 2x one shot or peck tap?

    We have a job that needs 400+ 3/4-10 and 5/8-11 holes threaded in 0.75” and 1.50” mild steel. For the 3/4-10 holes I am drilling with a 16.5mm spade insert drill as I have TSC. (Never used a spade insert drill before) Using a spiral flute tap, I don't see an issue tapping the 0.75” plate...
