Yep, I had an incident like that the other night, I was going to use my Kimball Midwest super glue and the end was the same as yours, the same thing happened! But, I "borrowed" a new one from work and all is well now. As is the on-volume knob for that '68 concentric tuning Zenith. Reinforced that with a metal clamp from another Zenith knob after I glued it. Glad you didn't get hurt, it really does burn the eyes. Belfuses are another thing I can get NOS from Chesters, if you need one you cant find just let me know. I also would love to see that chassis, I too have never seen that model. Seems very interesting, keep us posted!
