I started making my own glass hold downs out of wood quite awhile ago. I don't have any pictures because they are such a small part of any project, but I started making my own when I realized customizing them for each individual project was easier than trying to make the store bought ones fit a particular application.
I like making them personally, basically because they must be precise and small. Even if you needed several of them, it does not take long to make a batch when you get set up in production mode.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
