I frequently do smaller moldings in cabinet doors and other projects. I find it easier and safer to use a sled on my table saw rather than a miter saw. I can see my mark to cut by better this way. The small waste pieces don’t fly around as much. Years ago I was measuring a cabinet door job. As I was sketching the cabinets, the trim carpenter was cutting some small molding. The end piece flew off the saw and hit my face right by my eye. It bled a lot, but it turned out fine. However, it made me much more cautious.
This week I was working on a pair of sliding barn doors for a client. The top sections get glass so I needed to cut the custom molding. To me, this is the best way.
I set the miter fences away from the main fence so I can cut the length against the straight fence. leave that slightly long and then miter it. You have a little play to cut the miter. If you need to cut really small pieces, you can add toggle clamps to hold the work piece and keep your fingers away from the blade. T-slots are routed into the sled for other hold down clamps. I make some of my own and use some from Rockler and Woodcraft also. The miter fences are attached with bolts to threaded inserts mounted in the sled. They do have some adjustment in them. I can easily remove them for straight work.
If you are interested, at some point I will do a blog focused on various methods of work holding.
Thanks for looking!
