Plans for the BECO 2.0

Here are the drawings. I have made the new drawings to reflect the recent changes I have made, mixed with the changes that I should have made. Some minor details are not shown in the drawings. It should be obvious as to what is needed.
If you have any questions or comments, feel free to Send me Email

The plans are in DXF and PDF format. The FIG format is no longer used.

Please note the update column to see if you
need to get the latest drawings.

Note:The drawings are now complete (18-Jan-2010).
The Crankcase drawing was a bit crowded so I made a pdf with no hidden lines, and another one with no hidden lines and no dimensions.
I recommend using the DXF files.

All drawings were drawn with QCad on a Linux System. You can get a free demo version of QCad (Windows or Linux) from RibbonSoft.Com

The new drill chart has drill sizes for 90%, 75% and 60% threads.
When using small taps in steel it is sometimes difficult to get the threads tapped without breaking the tap. You can use a smaller percentage of threads for an easier to tap hole.
