I found your site and is very good. You pass beyond scratch the surface. I am doinf that.
Keep going with your work. I'm Romanian and I'm an absolute noob regarding Blender and 3D graphics in general, except CAD 
Many thanks! 
I can say that I'm learning Blender from you. I love your step by step instructions, I can read with no rush and take all the time I want to understand what the hell I'm doing.
Best regards.
Juan.
Hi Robert,
I just downloaded your book to help me with scaling issues between Blender and Pronterface with my Mendel 3D printer. I found the link to your book through the Mendel_users_guide. Keep up the good work and thanks. Don
Robert;
Thanks for the inspiration.. We actually use the 608 style bearings.. 
Oh, and another tool you may appreciate is an add-on for firefox:

Right click on a web page to produce a pdf - very satisfied so far!
Excellent source of information, I still check in here because of how much I learnt from your 2.49 tutorials.
Just in case, you mention on your home page about missing edge tools, are you aware of this addon in development:
http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Modeling/Edge_Slice
Not complete but getting there.
Congratulations for your website! The 608 bearing tutorial at 2.6 version are awesome! I hope see it at pdf version soon
just found your page from someone on the Blender facebook page.
PDF is great. I have always had trouble with accuracy in Blender. Many thanks 
Hi Robert , thanks a lot for your blender tutorial. I learn a lot using them. I am trying to build the bearing , I have done the rings and the balls now. I use blender 2.65 so I have to change something , but your work was great. Thanks a lot again.

I'm a newbie to Blender and I found your excellent Precision Modeling Guide.
I'm astonished with the extent and level of detail and quality in both the guide and your own work.
Also, by navegating the rest of your page I'm also amazed with everything you have done!!
Thank you SO much!! The guide will be an invaluable help for me from now on.
If the world had more people like you in it, it would be a MUCH better and nicer place!
