      When I attended the apprentice training centre we were encouraged to hone our skills with the hacksaw, but when it came to cutting large bar stock we could use the electric hacksaw, not especially quick but at least it took the backache out of the process. Now at home in my shed and some 45 years older I appreciate it helps to keep muscles in shape, but my recent string of projects have required me to cut a fair bit of large cross section material using a hacksaw and not only is it tiring it takes a long time, precious time I could use to do more creative stuff.

      I don’t have room for an electric hacksaw and the small band saw which was donated to me isn’t great at cutting metal in a straight line, is there something others use to cut bar stock up to 2 1/2″ diameter please?

      My arms and back are looking forward to an alternative.

      Cheers  :0)

        You don’t saw what type of bandsaw you have which would save suggesting teh same.

        I like quite a few other forum members use a Femi band saw. I find this quite compact and is said to be capable of cutting upto 105mm but I have done larger. Typically a cut across say 3″ round bar needs less than a 10 thou skim to clean up the end which is square enough for me.

          Hi Paul, you could get one of these, but they are a bit pricy though.

            There are several designs for making a hacksaw attachment for a lathe.

              When I’ve had to hacksaw larger stock I have cross drilled to remove as much material as possible. That leaves a lot of material to face off though. A pull-down saw is the better solution though.

                So fix the tool you have until it works as it should.

                It is not that the tool is incapable of perfoming satisfactorily. There are a good few online and published resources available to guide you in the process.

                The biggest win for the smallest effort will be a new, quality blade for the machine.

                  A new blade first ! If that does not result in a straight cut then check the blade guides and the rollers/bearings. I was given one of the 6X4 jobs because it cut on the skew, new bearings and setting up solved the problem. OR 4.5″ grinder and a 1mm cutting disc, I was cutting 40mm solid bar yesterday. Noel.

                    As some comments above check the set up is correct and blade is a good one.

                    However if you need to buy something like THIS is what I use small yet large enough for my needs and seems to cut square and cleanly. It does not take up a lot of room and the saw can be separated from the stand and be used freehand but this can be a bit of a faff as there are three alan head bolts to undo. It is designed for this function

                    I did not buy from there but screwfix but they don’t seem to have one now

                      Thank you everyone for your suggestions, I haden’t seen the horizontal band saw design before, I will look into this.

                      As for the fix your machine first, well I do agree that this should be the right thing to do, its an old Femi table top vertical band saw. The previous owner didn’t use it and gave it to me as a project or simply for the motor. I bought new tyres for the blade wheels and have a couple of new blades. Having trawled the internet for band saw set up I have now tried several of them and whilst it does cut better than it did my efforts at using it remind me of a child’s first efforts with a hand saw, it goes off course at the drop of a hat, however easy i take the work feed. Perhaps I will try again.

                      Never thought about cross drilling, thanks for the idea and I whilst i wasn’t too sure about a hacksaw attachment for a lathe, I will look into this cheers.

                      Having posted this note I did wonder if a circular chopsaw might be the right thing to go with? it will certainly be a good general purpose tool.

                        I would think twice (or more times) about a chop saw. I have one which I bought to cut wood and metal – so a tct blade. It does work, but the noise and flying red hot chips are no fun. I would certainly not use mine inside. After a couple of uses on steel I sprang for a small FEMI bandsaw. Far, far kinder on the ears and heart!!

                          I hear you Peter, I’ve only ever used a chop saw on site, it was a big one and it was outside. I don’t remember the flying chips of doom, perhaps I didn’t challenge the saw on that occasion.

                          It seems I need to work at my old band saw, although I am concerned at throwing good money after bad.

                            I don’t know what you were cutting – mine is fine on wood and OK(ish) on thin/small aluminium. If you were using a commercial device designed to cut steel I suspect it’s chip control was suitably engineered. Mine is an Evolution 210mm multi material  blade – chip control is not well engineered for steel.

                              Another option is a cold saw, like the Clarke CPMS1 225mm capacity, no sparks from this type, but not cheap either. Blades last a long while and can be sharpened for a few pounds.

                                You need a cold saw if that’s the way you wish to go. Same layout as a chop saw but much lower RPM and flood coolant. For home workshop use one of the horizontal bandsaws is probably optimal. They are usually on one set of wheels so a bit of ingenuity and they can slide back under a bench when not in use.

                                  Hi peter, I don’t doubt you for one minute, tbh for me it was a site tool owned by the company and I might have been a bit detached from such issues, probably cutting steel angle or unistrut.

                                    Thank you everyone I will investigate cold saw and horizontal band saw, looking at the curves on the cut bar stock I buy, they seem to be using a circular saw of some sort. Their cuts are amazing, smooth and square, I dream of replicating this  :0)

                                    In the mean time I need to give the elbow a rest!

                                      based on my experience the generic 4.5″ bandsaw can be set up to cut pretty straight.

                                      Forcing the blade will cause it to wander off the straight and narrow, so more haste, leess accuracy!

                                      However to do this, it needs to be in good order, and carefully set up.

                                      Already the need for bearings in good condition has mbeen mentioned, plus careful setting of the guide rollers. (They are on eccentric pins for adjustment. Once set, I have left mine alone!)

                                      (Having the drive pulleys running true is a huge help!).

                                      Setting the blade tension (I made a Jacques Maurel Tensionmeter) and setting the tracking carefully, with a new blade really improves matters.

                                        I usually spot my typos after posting and correct them using the edit button in the grey header line of a post.

                                        Usually plenty of edits in my posts although they do not seem to get listed in the new system.

                                            Angle grinder in a chop-saw attachment? A friend uses one of these a lot, although for smaller metal.

                                              I think you will find it hard enough to beat a simple cheap Chinese “junk” bandsaw for dealing with your material.

                                              If you dont have room for it, make room ! it will pay for itself in no time. I bought one many moons ago and I still wonder how I managed without it for so long. It cuts everything, and I never had to replace anything except the blades. 4″ round is no problem to it, while I do something else. Save your arms , and your time !
