Sorry we never got a chance to wheel this summer, maybe next summer

I was just about done tapping the first hole when it got really tight and the tap snapped inside the hole. I am trying to deal with this now and am thinking about buying a mill bit used specifically for drilling out the tap. Looks like my only option. I was using a four flute tap for it and I believe when I tap again I will try and get a 6 flute tap. I believe the bar is made out of some high strength spring steel and that is making tapping very difficult for me.
If the tap hasn't shattered in the hole I would recommend trying a tap extractor first. If your school has an EDM tap-burner your problem is solved. Instead of a 6-flute tap I will highly recommend a 3-flute gun tap for most anything you are tapping. This advice comes from an old guy who has spent many years in a machine shop.
No EDM here. I could only wish! I am not sure if the shop here has tap extractors if they do I will go ahead and resource that and extract it, but to buy one for this one broken tap looks to be too pricey. Especially since I can get another torsion bar for $15 at a pull a part. I may get something to drill it out. Looking at these http://www.2linc.com/tools_broken_tap_removal.htm
With the lathe I can feed the bit extremely slow so it will be a smooth process.....fingers crossed. Also I guess more flutes doesn't equal better strength? Or will the higher flute count clog up with fillings to fast?

Still stuck on the broken tap in the bar but I am picking up metal to build my arms for the sway bar. I think I will be looking for some 3/8" steel. I have been told 1/4" will get bent. Then we have a burn table here at school so I will cut them out with the drawing I drew up.Any progress on the sway bar?
Awesome man! So when you taking me to URE??![]()
