Hi Gerry,
Thanks for confirming that bit about being assertive. Interestingly,
while LMS doesn't list the smaller tool as suitable for the 7x, they
do list the 9x as compatible. As a friend of mine would say in a
dead pan serious voice, there are some strange cattle on them there
hills.

Hi John,
I forgot to mention the one about the diameter, and you are right
that you
need to crank the knob up tight to get the tool to bite and then
follow the
knurl.
THe smaller one does fit the 7x, I've had one for a couple of
years and it
works fine. I have no doubt that the slightly bigger offering from
LMS will
be good too and as you say when you take the other knurls into
account it is
still good value. You pays your money.......

Hi Rance, Gerry,
The other snippet I picked up somewhere in my reading is that you
shouldn't be too timid when starting the knurl. As the initial
imprints come around again the knurl teeth need to slide into the
previous imprints. To aid that you need plenty of lube. You should
also make the OD a multiple of the knurler pitch to help the
pattern
synch up. Being timid and starting really lightly is the best way
to
prevent that synch-up process.
Note that's all head knowledge from my reading. I wasn't told
about
these tips when I did metalwork at high school 35 years ago and I
recall I had problems with double imprints. My new scissor knurler
is somewhere over the Pacific Ocean in transit to Australia as I
type. I bought the larger LMS offering. The LMS site doesn't list
the smaller one as suiting a 7X. I'm confident it would. Chris at
LMS recommended the larger one - admitting it was his design -
and I
figured it was about the same price as the smaller one by the time
you factor in the cost of the 3 sets of wheels it comes with.
Hope that's helpful,
John

Rance,
without doubt i would say that the scissor type is the only
way to
go with
the mini-lathe because the machine is so light and flexible
(compared with
larger and industrial types). The scissor action means that
most
of the
forces stay in the tool and are not transferred to the spindle,
bearings
,slides etc.
Although it would be a relatively easy project I would suggest
that you have
done and buy a small scissor knurler as I did.
The one I bought here in the UK looks amazingly like (identical
even) the
smaller of the ones that www.littlemachineshop.com do.
I have had mine for about 3 years and it has been fine for
everything I have
needed which has ranged from 3/16" lockscrew though various
knobs
up to 1
1/2" knobs and hammer and screwdriver shafts mainly on ally and
brass. Finer
knurl wheels might be preferable if you are down at 1/8" or so
but
all my
results have been good, certainly I don't think you would be
disappointed
with it.
There is nothing particularly hard about knurling just align
throught the
centre of your work, tighten the knob, select slow speed and
apply
plenty of
cutting oil and just tighten up and keep applying oil as you
go
until you
get the knurl depth you need. If you are knurling a shaft just
slowly
traverse the carriage from end to end as you go tightening form
time to time
at either of the ends.
If you want an article might I suggest that you subscribe to
the
premium
content of frank hoose's www.mini-lathe.com site which covers
basic lathe
operation and some neat starter project in plenty of words and
pics and
idealfor a newbie to the minis. I subscribed when I got my
lathe 3
years
since and thought it was probably one of the best $25 I have
spent.
No connection with either of these sites, just pleased that
they
are there
for us mini-lathe types.

Gerry, others,
So what should I look for in a knurler? Buy just the knurls
and
make my
own mount or buy the whole tool? Seems to me that buying the
whole tool
would be best. Do I really need multiple tpi knurls? I'm just
a
beginner so I can't imagine needing more than just
the 'average'
knurled knob.
Any articles on how to use a knurler? Which type (sissor vs.
fixed)
would be best for a beginner? Thanks.
Rance
RE: [7x12minilathe] Re: Way Wear, Hard Gibs
I have the scissor type and apart from the physical
restriction
on what
you can knurl due to the throat they have worked very well for
me. Mine
will take just under 2" and in reality this has not proved a
problem
for the type of stuff i do.
