Just a quick tip today. I like to use yoga blocks in my 300guitars Shop to support guitars and amplifier chassis’ for different types of procedures. They are firm enough to bear some weight but will not harm the finish of guitars. You can order them in a variety of different sizes and colors plus you can cut them down for custom sizes and shapes. I found the ones I’m using on Amazon.com and they were very reasonably priced. I find myself thinking how I got along without them sometimes. Hope this tip helps you out with your projects. Namaste….
