I was building up an "89 Schwinn Circuit after S&S couplers were installed and a new powdercoat. Sweet and original Shimano Sante 7spd. It will be a travel bike and I bought Time Impact pedals to put on so I could use my regular shoes. Wouldn't you know but the Sante crank pedal holes don't go all the way through the arms and the Impacts don't have wrench flats, just an allen wrench socket on the end of the spindle. Hmmmm. Off to the grinder to grind some flats just right for a size 16 cone wrench. Worked pretty good except I had to take a little of the pedal body in the grinding process. Barely noticeable and they're on and working. One of those wrinkles in time.

Why don't the crank's pedal threads run all the way through the arms?
Could you have drilled out a hole through the plugged crank arm holes big enough for a allen wrench? This would have preserved any warranty on the pedals.

This is an '89 Shimano Sante group, complete. That's the way Shimano made the crank arms. There's no way I'm going to spoil a beautiful group like this by drilling a hole in the crank arms. Besides, I could easily end up trashing the threads and then where would I be? New crank time and a ruined group. It was much easier, simpler and less risky to grind some flats on the pedals. No warranty to worry about because they were used pedals and if I screwed them up would cost me less than $30 to replace on ebay.

Man that's a bummer. Got any pics of the finished product?
