The world of glassworking tools is a world of extremes

There are hand tools and full size glass lathes

This project is an attempt to create a tool in the middle

Contact Information

As the first production run approaches completion, I have registered some email addresses

sales@nqalha.com - All sales will be direct, through this address

info@nqalha.com - requests for pre-sale information should go here

support@nqalha.com - Once units are out in the field, owners can use this for help

Design Goals

Invent a single sided, glass spinning and positioning machine, smaller, lighter and more flexible than a rigid two sided glass lathe

The angular orientation of the workpiece should be easily adjustable, and be able to be locked in place. When unlocked, the machine should feel effortless and balanced, like an extension of your hand. When locked, it should support the piece being worked and resist the forces commonly applied in glasswork

Inserting a a workpiece should be easy, and once inserted, the piece should be held securely enough to resist the forces commonly applied in glasswork

The rotation speed, direction and more complex motion should be CNC controlled. When released from CNC control, the workpiece can be manually rotated

Controls should feel comfortable to the glassworker


Current Project Status

After a successful beta test, I'm confident enough to release the NQALHA for sale

The machined parts for the first production run of 10 are finished. Now it's off to the plater and anodizer

I'm working hard to have 10 units ready for sale at DFO

I have reserved a booth, and will show what I have, but I won't sell any until they meet my standards

Price will be announced shortly. I'm still working out some details

Preliminary Specs

Max RPM of the drive wheels is 300. Of course, the RPM of the workpiece depends on the handle diameter. Minimum RPM is 0.06, but can be made much lower if needed.. it's just math at slow speed. A static weight of 5 lbs has been hung from a handle about 7" from the face

During testing, Marcel made the largest solid object yet. Precise measurements are not available, so I rely on eyeballic estimates. The core of the object measured approx 4" dia x 2" long. A moil was constructed on a 1/2" steel punty, and the core was picked out of the kiln. After heating and shaping, a layer of milli rods was attached, bringing the size to approx 5" dia and 4" long. This object was workable on the NQALHA, but heavy paddle pressure stalled the motors. After the final layer was added, they object grew to approx 6" dia and 5" long. The NQALHA could barely spin it, if it was on center. The motors stalled, but the magnetic locks held. Looks like we found the limit

The NQALHA has two modes, rotation and step

--In both modes
The lever on the handle releases the locks, allowing free movement
The back button selects all axis lock or vertical lock only

--In rotation mode
The thumbwheel controls speed
The front button starts and stops rotation
The footpedal pauses and reverses rotation

--In step mode
The thumbwheel controls step size
The front button reverses direction and moves one step
The footpedal moves one step
