Contribute to Support Development

I try to make as much lutherie information and as many lutherie calculators as possible available here for free use. I want to make these resources available to anyone that can use them. But the fact is that building and maintaining this site and these tools takes time and effort. If you found something here that was particularly useful to you and it is within your means to do so, I would very much appreciate a contribution to help offset the cost of development and maintenance of this site and these tools. Thanks!
