Power hacksaw

[Toolmaker51]

pier, this is a great looking project. The blade frame and feed weight arrangement is very good, excellent addition with jack-screw on the vise too. Is there incorporation for blade lift on return strokes?
My preference for heavy material leans to power hacks - less expensive for super quality blades, way less floor space for same capacity.
May be biased...often used a 36" (with 2 or 3 tpi) monster owned by our collective Uncle Sam.
