HI All

New to the forum but been lurking round reading for along time. My question is what is the best way to cut round bar so that it can fit on my myford super 7. Cheap would be good and compact also. grinding wheel not ideal as I also use the workshop for woodturning.

Many thanks in advance the more options the better Brian

Hacksaw works for me, very cheap & compact

If its a big bit of bar tackle in in a few goes while doing something else in between and its always a good way to get warm in a cold workshop in teh winter

Having just come in from the workshop after sawing off a couple of slices of 2″ Steel.

Some people just like punishment

get yourself a small bandsaw, then you can do something else while its cutting, unless you like hard work of course.

mind you, as Jason says, it does get you warmed up, perhaps not the best thing in the summer.

Who said ‘ what summer?’

Angle grinder with one of those thin cutting discs. Always take it outside if the grit is a problem. Worth doing for anything above an inch.

Or find someone with a big lathe to part you off a few lengths…

Snooping around Fleabay might dredge up a donkey saw or two, I bought a Qualters & Smith 6″ donkey saw (with spare blades & coolant pump) a few months back for £60.

Down side is its very heavy but much better than trying to cut thick lumps by hand, it will chomp through 2″ solid EN1A bar in around 40 secs.

Plus the old saw came with a dual voltage 3 Phase motor so when connected to my Teco inverter gives me any cutting speed I like.

I think I have tried most ways of cuttting bar. Used an angle grinder, modified a chop saw to take both abrasive discs and a “RAGE” sawblade. All methods worked but very noisy and abrasive discs are messy. Still use a hand hacksaw for thin stuff but treated myself to a small hand held bandsaw a few weeks ago. (no room for anything bigger).

This works great and is the canines gonads as far as I am concerned.

Band saw is the way to go if you can afford the initial cost.

Alternatives are –

1 use hand saw

2 use disc cutter

3 buy in material cut to length

4 get a friend in to do the cutting

It’s reasonable easy to build a powered hacksaw out of scrap material, it could be made to use a standard blade, or an industrial (1″ wide) one. If you want to go silly, you can be like me, and make one for a junior hacksaw blade. Ian S C

Very nice work -as always- Mr Engine Builder. One of the nice things about sawing machines is that they can be quite precise- more so that someone wishing that they had never started. So with a bit of care, a good blade and good bearings you can save a lot of time cleaning up by letting the machine cut a nice surface.

In another video Mr E.B. uses a Rage circular saw. Got a sliding version from a B & Q offer some while back – what a nice tool. Does a great job on metal and wood. If you are into welding then it is a very handy chop saw for cutting sections to the same ( or in my case all different) lenths.

I part off longer lengths using a back tool post, insert parting tool and the fixed steady. I remove the S7 tailstock, mount the bar in the 3 jaw chuck and then bring the fixed steady up to the chuck and adjust the steady jaws so that they all touch the bar. I then slide the steady along so that it is about mid-way along the piece that will be cut off and part away. I support the cut off piece by hand as the parting tool gets towards the centre of the bar.

Works for me.

I seem to remember a similar saw in ME between 1976 and 1988 or there about. It used a klaxon (geared) type motor and the Hex bar slides

As with most things hacksawing by hand gets easier and faster the more you do it, the modern reinforced saws are really good I have one with 18 TPI blade for solid bar and another with 24 TPI for tube.

The thing to remember is let the saw do the work and not press down too much, if it takes a huge effort then your doing it wrong.

Hi all,

Here is a design for a power hacksaw using a washing machine motor that I found on the web.

Power hacksaw

I did not find the drawings that clear as I was looking for a sliding mechanism. It uses a double pivot system rather than a sliding mechanism.

I just had to cut a couple pieces of 22mm round BMS bar and I cut each one in under 55 seconds with just letting the saw do the work.

I use a Stanley 120110 Dynagrip heavy duty hacksaw with 18 TPI blade for cutting solid bar
