Drill Press Laser Guide
This a Laser Guide for my Drill Press which projects a cross-hair where the drill bit will contact the work piece. I designed this project in Fusion 360 and printed it on my Prusa MK3 3D Printer.
Instructions for this project can be found at Drill Press Laser Guide.

Remote CNC Stop and Monitor
This project provides an inexpensive means of remotely performing a STOP (ALT+S) to Mach3. This is accomplished with a Raspberry Pi (RPi) + Camera connected to a PC via a USB cable. Monitoring and activating the STOP on the CNC is done with a video streaming web application running on the RPi. Using this solution should be done at your own risk. I highly recommend contacting the manufacturer of your CNC, and purchase and install the recommended remote emergency stop specified.
Full instruction can be found at Remote CNC Stop and Monitor.
Note: This is not the same as an Emergency Stop (EStop) wired into your CNC control panel, but the execution of a hotkey to perform a STOP of Mach3.

Woodturning Live Center with Collet Chuck and Drawbar
Live Center with Collet Chuck and Drawbar holding a spindle. |
Turning long slender spindles on a wood lathe is a challenging task which can result in poor finishes due to vibration and chatter. Results can be improved when the stock is stiffened to reduce work piece deflection from tool pressure or compressive forces from the tailstock. Steady rest can provide this support, but are not practical when using a lathe duplicator. One method of stiffening the work piece is to hold it firmly on both ends and place it in tension. As a result, longer and thinner spindles can be turned with better results.
My solution for holding work pieces in tension combines a Chuck with Spigot Jaws on the headstock with a Collet Chuck, Live Center and Drawbar on the tailstock.
Instructions for this technique can be found at Woodturning Slender Spindles.

Digital Vacuum Regulator
This is a Veneer Vacuum Press (Vacuum Pump) which has been modified with a Digital Vacuum Regulator to operate with a selectable vacuum pressure. This device is a replacement for the Vacuum Controller in my DIY Veneer Vacuum Press built with plans from VeneerSupplies.com or JoeWoodworking.com. These are great plans and the pumps operate very satisfactorily as designed. However, I'm a tinkerer, and I wanted to enhance my pump with the ability to easily and readily control the pressure settings (without a screw driver) over a wider range of pressures with a digitally controlled regulator.
Instructions for the project can be found at Digital Vacuum Regulator on Instructables.

Wood Lathe Duplicator with Angle Grinder
My version of a Lathe Duplicator was inspired by The Homestead Craftsman, and his video entitled Homemade Wood Lathe Duplicator using an Angle Grinder. The differences in the designs are the type of cutting blade, table top and pattern mounting method. The goal of this design was to create turnings with finer detail and less clean-up, as well as adding versatility and adjustability to template mounting on the table top.
Instructions for building this duplicator can be found at Wood Lathe Duplicator with Angle Grinder.
WARNING! - Read and follow all manufacturer instructions, and use this Lathe Duplicator at your own risk.
Laminated 16ga steel table top and pattern secured with Magswitch Model 150 magnets. The angle grinder has a Viel Tools Model D-15-80-5 Carbide Cutter. |
