Woodturning Live Center with Collet Chuck and Drawbar

I needed a means of holding and turning long thin spindles in such a way as to reduce chatter and vibration.  Live centers can introduce some problems if the tailstock is over tightened compressively.  Therefore, I wanted a means of holding the stock securely and without axial compressive forces which would contribute to vibrations and chatter.

My solution was the combination of a Collet Chuck and Live Center with a Drawbar.  Mounting this combination in the tailstock and securing the work piece in the collet chuck.  Next, move the quill on the locked tailstock  away from headstock and create some tension in the workpiece/spindle.  As a result, the workpiece is held firmly and steadily by the collet chuck.

One thing I noticed after turning very thin pieces (5/16" or 8mm) was the thin spindles demonstrated the ability to oscillate axially when the lathe was stopped.  Exerting a small amount of torque to the collet and releasing it would cause the spindle to oscillate axially in the fixture.  In any case, I have been very happy with the performance of this live center.

CNC Carved Spoons and Spatuloons

These spoons were my first two sided project
attempted on my CNC Router.
Spoons provided me a challenge to create a two sided project to practice and learn the skills necessary to attempt my Continuous Arm Windsor Chair Seat with CNC Router project.  My first attempt at cutting out spoons was with 3D models purchased from TurboSquid, and proved to be satisfactory for my test purposes as well as practical cooking utensil.  However, I wasn't satisfied with someone else's design, so I created my on with Blender.

Digital Bandsaw Blade Tension Gauge

This is a electronic/digital gauge to measure the tension of band saw blades in order to get the best performance from the blade and the saw. Once installed, this device provides a convenient method for measuring the force or tension a bandsaw blade without interfering with the blade guides or attaching something to the blade. This gauge/scale can be setup to display either imperial (default) or metric.

Details of this project can be seen at Digital Bandsaw Blade Tension Gauge at Instructables.  Information about this gauge can also be found at BANDSAW TENSION GAUGE USES RASPBERRY PI AND LOAD CELL at Hackaday.

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.  Basically, the only things I changed from the original design is the grinder blade, and the table surface of the duplicator.  My modifications were made to create turnings with a little finer detail and less clean-up, which the carbide cutter provides, and more versatility and adjustability for mounting the pattern to the table top.

My Failed Attempt to Steam Bend Kiln Dried Wood

My current project is Curtis Buchanan's Continuous Arm Windsor Chair.  One of the main parts and most difficult to construct for me was bending the arm.  Since I don't have a ready supply of green wood, nor the space for splitting and riving wood, I thought I would attempt to steam bend kiln dried wood...How hard could that be?  Well, it was a waste of time.

Continuous Arm Windsor Chair Seat with CNC Router

This is an explanation of how I created a 3D model, and cut a Continuous Arm Windsor Chair seat with my CNC Router.  The plans I used for this seat are from Curtis Buchanan's Continuous Arm Windsor Chair.
