Sand Bag Damping Sheet Metal

sand bag damping sheet metal

Sand bag damping of sheet metal is not new. Using sand bags to dampen down structures is not new, not even to this blog. Previously I used sand bags to dampen the column of the Sieg SX2.7. They added a very small, but still significant level of damping.   The trouble with large thin sheets of … Read more

CNC Holding Tabs

kant twist clamp sheet

What are CNC holding tabs? Coming from a world of manual machining this is all new to me. However, when you start machining parts from sheet materials you will inevitably end up creating islands. With rotating tool bits these islands don’t just float away. At first I created these tabs manually by dividing the perimeter … Read more

Kant Twist Clamp Project

frame for a kant twist clamp

The Kant Twist clamp project is my first proper challenge with CNC. A very small version of this clamp. All because I’m using a Genmitsu 3018-pro engraver that in my own way has been upgraded to a 3020-pro max. This is a small desktop CNC. However, I’m a model maker and small clamps are normal … Read more

Squaring up the Genmitsu 3018-pro

Genmitsu alignment

Squaring up the Genmitsu 3018-pro after some upgrades. Normally this would be done with a DTI held in the chuck. Rotate it back and forth to understand the fore-aft tilt of the head. Rotate it left to right to understand the tilt of the head. In this way it is possible to very accurately adjust … Read more

Genmitsu 3018-pro to a 3020-max

Genmitsu 3018-pro to 3020-max

This is my homemade  conversion of a Genmitsu 3018-pro to a 3020-max. Maybe not exactly a 3020-max, but a lot of the changes have been included. Plus I think the spindle upgrade I’ve made is better. The spindle upgrade was designed and made some time ago. It has significantly improved the stiffness of the spindle … Read more

Tiamu Z-axis for Genmitsu 3018

Tiamu Z-axis upgrade

Just bought a Tiamu Z-axis for Genmitsu 3018, my original plan was to machine this complete assembly from scratch. Then reason kicked in and I thought that as I could buy this for around £100 it was not worth me spending probably 3 days designing and making parts. Plus it was delivered really fast. However, there … Read more
