I could do with a small power hacksaw that can be stashed under the
bench - I don't have space for a big one.
Does anyone either have the plans for one, a redundant one or have built
one from a kit (and yes Gareth, I know what you think of Blackgates
already......)

Thanks

The Rapidor ones are worth looking out for, that's what we have at
home, very well built and often from schools.

Haven't one to sell though...:-((

Avoid Blackgates like the plague.

Do not part with any cash in their direction until you have
unwrapped every single casting from the over-sellotaped
excessive newspaper wrapping in which each casting is
cunningly sealed.

Caveat Emptor.

Blackgates should be renamed as, "Blackguards"

I 'd advise you not to go for the Blackgates kit - it's a poorly
produced pile of poo.

Caveat Emptor - inspect _EVERY_ casting by completely unwrapping
it from the paper surround in which it has been cunningly wrapped and
sellotaped
over and over, berfore parting with any cash in their direction.

Blackgates should be renamed as, "Blackguards".

There you go again Gareth, blaming others for your fu** ups. Just like your

Charles,
Keep a lookout for a Kennedy Saw on ebay etc.
There is not one there at the moment but there is a small picture of one
here
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=40003&item=38458500
04&rd=1&ssPageName=WDVW

AFIAK they make (made?) two sizes - both use standard hand hacksaw blades.
Both would fulfill your 'under the bench' criterion
That is where mine lives!

Good Luck

Sadly it turns out that a Rapidor will be too big (Peter Forbes was
kind enough to measure his machine for me). So it's either a Kennedy,
Blackgates or make one.

It would appear that two designs have been published recently. One in
Model Engineer volumes 168 and 169 by R J Cochrane. Anyone know
anything of that design or have spare copies/volumes for sale?
The other was in MEW issue no 1. I used to have all the MEW's but
issues 1-5 got lost in a house move so if anyone has a copy of the
article (I don't expect an issue 1 of MEW to be available!) I'd be
grateful.

Thanks

I've also been looking for a similar small machine, and one that
caught my eye is available as a kit from Woking Precision. Take a
look at:

I suspect this *might* be the one described in issue 1 of MEW. I
have a copy of the article coming to me through the ether (thanks to a
friendly stranger). However in issue 6 or 7 of MEW there was a footnote
about finding the right parvalux motor with the reduction gearbox which
makes me suspect that this is the MEW version.
However it doesn't look much for 130 quid - but does show how easy it
could be to fabricate one.....

Knowing that 'most' Parvalux motors are fractional induction types, it
makes me wonder what sort of size material this would handle?

The Rapidor has a 1/2 or 3/4 hp three-phase motor, and will cut up to
about 5" round, the smaller kits may be Ok if you don't need to go to
those sizes.

Note that this appears to be designed for 10" hacksaw blades. Finding
an ongoing supply of these might be difficult.

I have a Kennedy which is certainly of the right size. I do have a couple
of complaints; it has a smallish work size envelope (< 2 inch round and
mine at least starts to struggle well below this), and the in-built vice
is poor (hard to grip many objects and it works itself loose).

Before I bought the Kennedy I was contemplating a self-build and found a
number of pictures and designs online. There are several within the
Yahoo group archives including some scans of the ME articles. Also I believe the
Gingery book series includes one on a power hacksaw.

After posting my last message I had a look at the Eng Pages provided by Chris Heapy.
Have a look in the September adds and you may find two adds at least of interest.

It may be worth while just giving them a ring to see if any are still available.

Charles,
I have a home made hacksaw powered by a 1/4 hp motor driving via a worm
gearbox. It uses standard hand hacksaw blades & will happily cut through
3inch square bar, which is as big as the vice will take.

I have a Kennedy Benchmaster, and found it very useful, cuts around
the 4" mark never too sure. Much used and would suspect much modified
in its life, no catch to keep the blade up and does not have the
raise and fall movement as seen on some of the bigger Manchester power
hacksaws but it does me. Certainly saves the arms.

Now I may be wrong here but I have seen a smaller Manchester power
hacksaw or Rapidor hacksaw of around the same size as the Kennedy.
Also seen the big three phase monsters with the rise and fall that
could go through 6 " plus of steel bar, noticed that GabdM have a
range of hacksaws so would suggest they are out there to find.

I will ask the dealer I bought mine from to see if there are any more
to be found.

I just bought a benchmaster senior hacksaw but the parts for mounting the blade are missing and a made up clamp in there place.

Does anyone have one of these they can send me pictures and measurements to put her back the way she should be......?

Charles,

I have a couple of Parvalux motors with 90 deg o/p drive. The motors are
three phase though. They are 1/12 HP and look about the right size. It
might be the reduction drives could "re-cycled" I'd need to check but from
memory they are 9:1.

Thanks to all -

Neil - The Blackgates design also uses 10" blades which does seem an
oddity these days. And which Yahoo archives are the ME articles in?

John - 1/4 HP seems to be the requied power (that's what the Woking
version uses aswell.) And I have a 1/4 HP motor on the shelf unluckily
not with 90 degree gearbox though.

Steve - Thanks for the offer - when I've sorted out the best plan I'll
come back to you.

Charles, not sure if it was the one Neil refers to, but try the
mwsmalltools group as this seems to be where the hacksaw stuff lives.

There's a family of mw**** groups which have materialised as separate
groups because of the Yahoo limit on file space. The others are not
directly related to your hacksaw query, but well worth a trawl round them
when you have time (mwmills, mwmills2 etc.)

Thanks for the pointer - I'e been away on holiday and had missed it.

However I've looked at the plans available and reckon it's easy to
make one - after all it's not a precision peice of kit is it. I've
also found a large 90degree reduction gearbox living under the bench
that'll handle a 1/2 hp motor that I have......

Whilst on hols I did some thinking and have a single phase Alba 1A
shaper that I'll be parting with soon. If anyone is interested please
get in touch.
