Kennedy Hacksaw

I just got a nice kennedy reciprocating hacksaw. Apart from a broken belt guard bracket it looks in great original condition.

Im a little donfused about the damper pot though. Is the damping adjustable? If so, how? Im not sure how to set it or how much oil to put in it.

Ive only really got some hydraulic oil, or maybe some engine oil. I know thats not ideal but got to be better than nothing right?

Thanks.

Graeme,

I have put a message in your in box.

Thanks.

I had one it was erm ok not OK. I found I could cut metal faster with my 4.5" grinder with a slitting saw in.

As far as I know the damper is not adjustable just fill it with thick oil. Have a look at tony the lathes web sites.

Graeme,

If you want to send me a message with your email address I will send you a pdf of the original instructions.

Its only one page.

Or maybe that's what Lambton has done!

There should be a little lever on the top of the dashpot which oil.when rotated controls a disc valve and the lowering action. The oil is not too critical - I think I used ordinary engine oil. My machine is well worn but still ploughs its way through thick steel. The addition of outboard support allows the cutting of short lengths a la Myfordboy design. A piece of equal diameter material in the jaws also helps to grip short lengths.

I have a 90 which had belt slip when I got it. That was do to wear on the saw frame guide hex and arm, filing a relief chamfer front and rear of the guide to allow it to dodge the wear ridge fixed that. If yours comes with a very loose guide thats the reason why.

You should have two bits of bent rod sticking out of the dash pot, one attached to the arm and one free. Twisting the free one (half turn) will change the damping rate least to most. Engine oil works fine in mine. If the oils is too thick or too much damping selected your cut rate will be pathetic. Mine is happy with an 18tpi blade, but it has a bigger motor than yours. It will still bind and stall if the work piece moves in the vice, also watch outboard support.- too much and the cut closes on the last strokes, binds, stalls the blade and gives a smoking belt.

Make sure the crank rod is oiled properly.

Enjoy fairly quiet cutting

Resurrecting a very old topic.

I recently bought one of (what I think is) the smaller versions. Can anyone tell me which is the correct direction for the blade to face? Do these machines have any other foibles?

Kennedy instructions on the net states this M/C cuts on the forward stroke.

Mine cuts on the forward stroke. I would not be without it, great little machine!

Where I worked once you wouldn't believe the amount of times I saw people put hacksaw blades in the wrong way round. Basic fitting knowledge.

Thanks for the info gents. Does Robbo, who posted here on 07/03/2015, still lurk hereabouts?

Click on his 'forum posts'. It may give a clue.

I never thought of that. Thanks. I'll give it a try.

Interesting, we have a powersaw at work. It cuts on the backward action, it was a new machine to us and the cuts best this way.

I'm wondering it we should change the phase rotation and the blade direction?

It's not infallible but a general rule is for the cut direction to be from the moving jaw towards the fixed jaw,

Has anyone any further information on these machines they could share please?

You need to look at your messages. You message member, member messages reply!

I love my Kennedy hacksaw! I call him John the damper is adjustable indeed, there should be a kind of lever coming out of the oil pot which you can turn to make the adjustment.
