I found this thread in a web search. I have an old Delta Model TS200 table saw with the part #899960 handle assembly, that in this instance is a blade tilting lock handle, and that had the splines stripped inside of the handle as I found out after removing the spring loaded screw, holding it in place. Chuck (TellicoTurning) gave me an idea, so I removed the spline nut with a pair of locking pliers, revealing a standard threaded bolt sticking out from the front of the saw case with a washer still on it. I found it to be a ¼"-20 thread size. I initially used a standard hex nut, tightened with a wrench, then decided that a winged nut might work as well. I couldn't find my bag of spare winged nuts, so I went to my nearest box store (Lowes) to obtain one. I happened to find in my search, a Hillman clamping knob w/ ¼"-20 female insert (Item # 423502 Model # 884510). I've since also found a Hillman bar knob (Item # 139701, Model # 881354) that may work for some people as well. Upon returning home, a quick search found my bag of spare wing nuts. Both worked fine but with my older hands not as strong as they once were, I decided on the clamping knob. So, Duane (DHappold), I hope you found something that worked for you back in 2013, but hopefully this will help someone else in a future search.
