I have two old Hegners, 18 and 14 inch saws. There isn't much original on my saws. I get rid of anything that is redundant. The long bolt to tighten the table angle is replaced with a hex head bolt and is now out of the way. The little box covering the lower blade clamp is gone. I removed the arm that held the foot as it had no useful purpose other than the foot. Even the blade clamps are crap. Even the quick change clamp is only a mediocre improvement. So why do I LOVE these Hegners? They are easy to improve. The Germans are hardheaded as I should know being one. They have had their crappy blade clamp design for 400 years. To change would be to admit it is flawed. Hawk had the right idea. I made blade holders similar to those used on the 16VS Hawk, the barrel style. They work so much easier. It is much easier to place the blade in a little hole than using the thumb and forefinger to guide the blade into the little slot, holding it in place and then tightening the knurled knob. I have neuropathy in my hands and feet. I no longer have fine motor skills. That's why I had to give up clock repair, model railroading and sundry other things. Hegner changing clamp design would be admitting the saw can be improved and we can't have that. In spite of all that I LOVE the Hegners, clamps or not. They are so durable. Had Hegner been in charge of building the Panzer Germany might have won the war.
