This has been my cutoff saw ever since I started metal working. It is just a handheld bandsaw lashed to a homemade plywood frame.
It has been quite satisfactory on flat bar stock and rod stock less than 1.5 inch diameter.
It fell short, however, when I started making bronze frame reels. The material that I wanted to use (c544) comes only as rod stock, and I needed 3 inch diameter. It was difficult to get a straight cut because the plywood frame was not sufficiently rigid.
When I needed to make a lot of cuts on 2-5/8 inch diameter aluminum rod stock, I decided that it was time to upgrade the saw. This is my new Model 4829 saw from Little Machine Shop.
It appears that the same saw is offered by Grizzly. Grizzly stocks repair parts but LMS does not. I know, because the first time I changed blades I ruined a rubber tire.
LMS sells a 10 tooth/inch blade that is much better for large stock than the 14 tooth/inch blade that comes with the saw.
So what is the deal with the 10 pound weight?
The saw hinge has a built-in spring that lifts the saw. The extra weight partly overcomes the spring torque and makes cutting easier.
Update 20 July 2018: For dealing with larger diameter round stock, it helps to have a custom vise:
