I wanted a precise way to cut steel for my upcoming CNC mill project. With that said a comercial chop saw was too messy and imprecise, and a comercial powered hacksaw was ~200$+

I designed and built my own using parts from my bin and about 30bux in home depot parts.

Here she is.

That's pretty cool.

Do you get any alignment problems from blade flex?

No alignment problems as there is a guide. If the blade is tensioned properly it will not have much flex. The finish it leaves shows perfectly straight cuts. I have more updates to the design I will add at a later date. Including a blade guide that bolts to the chuck.

Extremely imaginative. The counterweight made me smile is there more to it than a printed lump? Is the front of the saw weighted? If you alter the throw of the eccentric bits you would improve cutting speed by not lifting the blade quite as much on the back stroke.
Very nice work.
