Get one with a brushless DC motor, direct belt drive and no gears.

I use and am sold on FreeCAD. It's free and widely supported. Latest version is 0.20. Takes some effort to learn but it's worth it.

Thanks for your input. I have had success using Android with Bluetooth but cannot get Bluetooth to work with my PC. If I use gSender on my PC with a USB connection to the UNO, everything works fine. Not so when I try this with a Bluetooth connection. It appears that gSender doesn't like BT...

I've converted my Grizzly G0781 to CNC. Now, I want to control it from my office by means of Bluetooth. I've attempted to set this up using an Arduino UNO and either a RN-42 or HC-06 BT module. My plan is to use gSender on my Windows 11 PC to control the machine replacing the USB cable with...

I have just finished the hardware modifications for upgrading my Grizzly G0781 milling machine to CNC. Now, I am working on the electronics and software. I want to control the machine wirelessly (Bluetooth or WiFi) and have spent untold hours searching for good information on how to do this...

I had a friend who worked hard and long to develop a method for economically recycling lithium batteries. He was not successful. I'd like to know more about the process GM plans to use to rebuild them. How much and what kinds of waste will be generated and how will it be disposed of? What...

Don't forget that around 70% of the electricity used to recharge is generated from fossil fuels. So, when discussing energy efficiency, remember that the energy conversion from BTU in the ground to BTU at the charging station is around 50%. Then, there is the loss from electric to chemical to...

If it makes sense, change will come w/o government involvement. If government is pushing it, it probably does not make sense. Switching to electric to reduce reliance on fossil fuels makes sense if it is allowed to proceed at a pace that does not disrupt our economy. When it is forced by...

Government will never give up the tax revenue it gets from fossil fuel usage. As more people go electric, government will find ways of maintaining the revenue stream probably by a tax on EV recharge.

Amen!

Several years ago, Lowe's came out with their own brand "Kobalt" lithium powered garden tools. I bought a blower, hedge trimmer and string trimmer. They all used the same battery. I got two batteries so that I always had one charged up. I'm still using these tools and they have worked...

I don't like any of it. Oil and water are stinky and a mess to clean up. Air blows swarf all over the place. Except for threading, I use nothing if possible. Even then, I use just a squirt or two of cheap cutting oil. I think it is relatively easy to tell if a lubricant is really needed. I...

Just a comment about wood working vs machine shop. I've had both, but the dust and environmental concerns about paints, varnishes etc. in the wood shop were more than I wanted to deal with. I had a good dust collection system but there was still a lot of fugitive dust (and solvents). For...

Hope you are getting some help. Since you are interested in hobby machining, you should learn CAD. There are several free CAD apps on-line. My favorite is Freecad. Learning it will take time and lots of attention, trial and error. If you get good at it, you might even be able to do work for...

VERY nicely done!

Don't forget that using batteries allows the measuring circuitry to be completely isolated electrically from the machinery. This avoids ground loops and the electrical "noise" that raises cane with sensitive electronic devices like the iGages. Sure, there are ways around this but they are...

Found your info on 5 cylinder radial engine. I've ordered plans and hope to start the build soon.
