Okay Already Seems my Triangle was NOT my only problem. I did spread the triangle apart using the 2
Wood Plank suggestion (it worked well...thanks). Glitch #2 appeared, the Axle is 1/5th inch larger
in Diameter than are the dropouts and since I already fried my Dremel, am going to have to find a
metal file and widen the dropouts Thursday morning. Can it get any worse??...I have a box of these
new axles and every frame I tried appears to have dropouts too small....hmmm guess this is why the
axles were on sale. What is the line again about there being one new one being born every minute.
