Yes you can. I am using a 3-5/8" crown at Home Depot for kitchen cabinets which has a 38 degree spring angle. I set the ts55 base on 34 degrees and set the mft angle rail on 31.5. Then use your guide rail and cut at 90 degrees (normal) with the crowns top edge closest to you. It lines up perfectly. I use a gel ca glue with the spray activator and just hold the miter together for a few seconds for it to set. Brilliant and spot on. Not sure what other angles you need for other crown, but it works well with the 3-5/8 plastic man made material from Home Depot. [big grin]
