Open the project in Easel.com and adjust material, bit and machine size if needed.
Place a piece of 300mm x 300mm MDF on your X-Carve and run through the the Easel.com steps to carve the parts out.
Once they have been carved out you can use a sharp knife to cut the tabs holding the pieces in place.
There are several main pieces with slots cut that match the width and spacing of the mounting holes on the X-Carve.
Use 5mm machine screws and washers to secure them to the waste board.
The thinnest part goes at the front and is aligned with the graphic on the waste board this can be left permanently in place for quick setup of the workpiece.
The 2 medium thickness pieces go on the left and right of the wast board, the left ones can be permanently left in place and aligned with the marked line on the waste board.
The widest part goes at the back of the workpiece.
The 3 smaller parts are for odd shaped parts and spares.
You can adjust the right and back parts to apply pressure to your work piece before tightening down.
For added pressure leave about a 3mm gap on the left and right hold downs and then push the wedges in the gaps and give them a slight tap with a small hammer to hold the work piece firmly.
All you need to do is use a thin 3mm piece of MDF under the work piece like in the image shown.
