Mechanisms for Projects

I have introduced a collection of mechanisms, so that you can use them for your own projects

The selection comprises 6 sizes of Geneva mechanism, an inverted Geneva Mechanism, a couple of intermittent motion mechanisms, a couple of Rotary to linear motion devices and a Cardan mechanism.

The files are in the form of DXF files for use in a CNC machine and PDF file so that they can either be drawn onto the wood or pasted onto the wood for profile cutting.

I have not been particular about sizing the thickness nor the hole diameters as these will all need to be determined when you incorporate them into your own designs.

All the mechanisms can be scaled both up and down with no detriment to there function.

Drawings for this clock in PDF format can be downloaded here, These free files are restricted so that you can only view them on screen but not print them. Clicking to the left here will download the PDF file directly to your browser, may take a few moments so please be patient.

A sample from the DXF/DWG files is shown when you Roll Over the arrow .The actual files purchased above are included on one large sheet so that they may be directly loaded into your CAM program

To print only a single item of the drawing to scale using Adobe Acrobat Reader,  do the following

Go to  Edit  then click on   Take a snapshot

Move the cursor to the top left of the item you want to print and hold down the left mouse button whilst you drag a box around the item.  The inside of the box turns blue and you can now go to  File and then click on  Print  . This brings up the print dialogue, make sure Selected graphic  is selected and that the Page scaling is set to  None  and the click on  OK,  .As long as your printer is connected you will have printed the item at size.Do this for each item you want to cut out.

You can download the DXF and PDF files for the mechanisms for $26

The DXF files are contained on one large sheet so you don’t have to extract them from the drawings themselves, but can pick the profiles individually as you need them.

Drawings for the mechanisms in unrestricted PDF format  are drawn to scale so that they can be printed at full size on either A3 or Super B papers.
