This should work for any size object that I want to work with, in any position on the bed. \u00a0I attached 2 T-tracks to the bed, outside the working area. Then I made a sled with 90 degree corners with another T-track mounted on it. This will hopefully allow easy clamping of any size stock at any location on the bed. I plan to use a few different styles of clamps and\/or stop blocks to attach to the t-tracks. It will be easier to show pics than try to describe the setup and the many options it will allow:<\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-81\" src=\"https:\/\/i0.wp.com\/thoughtfulconcepts.com\/blog\/wp-content\/uploads\/2017\/03\/IMG_20170223_211726-Medium-300x225.jpg?resize=300%2C225\" alt=\"Workholding T-tracks\" width=\"300\" height=\"225\" srcset=\"https:\/\/i0.wp.com\/www.diycncdesign.com\/blog\/wp-content\/uploads\/2017\/03\/IMG_20170223_211726-Medium.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.diycncdesign.com\/blog\/wp-content\/uploads\/2017\/03\/IMG_20170223_211726-Medium.jpg?resize=768%2C576&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.diycncdesign.com\/blog\/wp-content\/uploads\/2017\/03\/IMG_20170223_211726-Medium.jpg?w=1024&amp;ssl=1 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>On the other end of the bed, I attached a\u00a0T-track with some low-profile cam clamps, that wedge the spoil board in place. I will eventually mount this t-track to the longer tracks, similar to the image above.<\/p>\n<p>While attempting my first cuts with the machine, I learned how much pulling force an upcut end mill has. I will need some clamps to hold down my spoilboards\/fixtures. In addition to the material being pulled up towards the router during cutting, the wedges I used (only hand tight) vibrated loose and the stock moved during cutting.<\/p>\n<p>Switching gears from the dust shoe components that I had planned to cut out, I modeled some clamps in Fusion 360 based on a few designs I had seen. Here is video I made showing the first successful project with this machine and the finished clamps that it produced! Still not having clamps for this operation, I hammered wedges in place to get them very tight and I also used longer screws to hold the stock down more securely. \u00a0Everything worked out well.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/g6vr5ToQqxI?ecver=1\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I came up with an idea for a simple way to quickly hold things in\u00a0place on the bed of the machine.
