    2", 3" & 4" NPT Internal Thread Milling w/ VCarve Pro and CNC Router

    Holy Crap, that is complicated modeling for such a simple hole. Hopefully there is an easy way to do this with VCarve Pro.

    2", 3" & 4" NPT Internal Thread Milling w/ VCarve Pro and CNC Router

    It is actually going to have a 2"/3"/4" male adapter screw into it, but it doesn't have to be completely water tight. This will be going into a koi pond, so algae and bacteria will grow around the fitting pretty quick and seal up whatever small amount of water goes around the threads.

    2", 3" & 4" NPT Internal Thread Milling w/ VCarve Pro and CNC Router

    I have seen other people get called out for posting in the other forums when they were specifically talking about a woodworking CNC, so I posted it here. Maybe next time I will take a chance and see if i get yelled at ;)

    2", 3" & 4" NPT Internal Thread Milling w/ VCarve Pro and CNC Router

    Thank you. That makes sense about the leading/trailing edges of the cutter forming the thread. Seeing as how my cutter is already 60* and has a diameter of 3/4", it is probably going to cut a ~65* thread if i am thinking about this correctly? That should be fine for my application, but it...

    2", 3" & 4" NPT Internal Thread Milling w/ VCarve Pro and CNC Router

    I am a complete newbie when it comes to CNC router thread milling, and I am overwhelmed when I am searching for single profile thread mills on MSCDirect. My immediate need is for a single profile thread mill that will be able to cut internal 2", 3" and 4" NPT threads into 1/2" thick Type I...

    Mini Vacuum Pump ~24V recommendations???

    I have seen a few people talking about Thomas and FNK brand names for these small vacuum pumps. Has anyone had any experience with these brands and can give me some pointers?

    Mini Vacuum Pump ~24V recommendations???

    Good point... The turntable will have a standard 3-prong 120VAC 15 Amp power cord, so having a 120VAC vacuum pump would work just fine if it is small, oil-less, and relatively quiet. That is why I didn't want to use a Venturi pump. I guess I wouldn't always need that kind of vacuum pressure...

    Mini Vacuum Pump ~24V recommendations???

    I am looking to make a small rotary vacuum table that is powered by a 24v stepper gear motor and i figured I might as well try and source a small 24v vacuum pump that can mounted to the turntable frame for easy use. I found a few options on Amazon that were oil-less diaphragm pumps, but they...

    Power Cable W/ a structural guide wire inside the jacketing???

    WOW!!!!!!!!! You really put some thought into this. Thank you very much for that. I already have TWO GFCI circuits on my house (one in the downstairs soffit and one upstairs) but I might run a 3rd circuit after reading your comments on resistance and the speed of the magnetic trip. I ended up...

    Power Cable W/ a structural guide wire inside the jacketing???

    Thank you for taking the time to reply, and sorry I didn't get back to you sooner. I have been up to my eyeballs in fabrication work so I haven't been on social. The lamp pole in fact does have a counter-acting guide wire on the other side, so the pole remains in a straight alignment.

    Power Cable W/ a structural guide wire inside the jacketing???

    EDIT: Sorry if this is SUPER off topic for this section of the website. I am trying to save myself a couple steps in my Christmas Lighting Display, and was wondering if this type of cable... - Already exists - Is an economical option Longest span will be around 300' from turnbuckle to...

    Bungee Cord Halloween Scare. Need help with the physics...

    Thanks for helping me switch gears on this project ;) I only wanted to use the bungee idea because I HAVE IT and I thought it would eliminate a good bit of electronics from the system. But once i started down the line of having the 1/10HP motor retract the figure, electronics came back into...

    Bungee Cord Halloween Scare. Need help with the physics...

    I think I understand your curved lever idea. We would start with the lever in the 3 o'clock (horizontal position, having the most counterweight force acting against the bungee cord), and then as the scare creature moves forward the lever starts to rotate CCW towards the 12 o'clock position...

    Measurements....

    Bungee Cord Halloween Scare. Need help with the physics...

    I want to create a halloween scare setup that will feature an 1/8" 7x7 wire rope that will be suspended between a house and a tree or light pole (depending on the results from this thread LOL ). I was going to secure one end of a 50' long, 1/2" diameter, polypropylene wrapped bungee cord. This...

    Quincy 350 Compressor won't build more than 20PSI...

    I did not remove the inlet screen, but i did look it over from the outside and it looked to be in good condition. I bought a cheap hour meter and will get that installed soon. This way i know how many hours the oil has been used for. IR recommends 2000 hours for the oil change with the...

    Quincy 350 Compressor won't build more than 20PSI...

    HOLY CRAP, that was disgusting!!!!! I am sooooooo glad you told me to do this. I never would have thought that the crank case would hold so much nasty old oil and junk down in the bottom of the unit. There was roughly 3/4" thick of sludgy, milky, nasty oil that i had to suck out with a small...

    Quincy 350 Compressor won't build more than 20PSI...

    I finally got the new unloader rebuild kit installed, and it is now obvious to me why I was getting the results from my post earlier in this thread. I said it right in my testing procedure... "The following sequence was performed with roughly 30 PSI in the receiver tank (leftover air from...

    Quincy 350 Compressor won't build more than 20PSI...

    Thanks for the heads up. I will do that when I get some downtime. I have that exact oil on hand and will be swapping over to it once I have everything worked out. I did use quaker state high mileage oil on the last refill because REAL compressor oil is not cheap. I didn't want to refill with...

    Quincy 350 Compressor won't build more than 20PSI...

    THANK YOU so much for spending the time and holding my hand through this ;) !!! I bought my QR-350 at a local auction from a metal fab shop that made pressurized tanks (similar to what the compressor is sitting on and much larger) so it was rode hard and put away VERY wet and dirt for many...
