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.

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.

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.

Hi,
Based on an article in Model Engineers Workshop I created this spread sheet which figures out the correct OD of what you want to knurl so that the knurl works out.
www.pacificsun.ca/~john/ELS/photos/Knurling.xls
Just enter in the Knurl dimensions and tooth count. Then the diameter of what you want to knurl. It then calculates what the closest diameter is that will result in a nice finish. Turn your work to that diameter and knurl away.

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 --- In 7x12minilathe@..., "gerry waclawiak" <gerrywac@...> wrote: Rance,

Usually, you sort of match the knurl to the work diameter; little things with coarse knurling look odd. On the 7xX, the machine isn't rigid enough to be happy with a fixed knurling tool; the scissor type is the way to go. Along the same lines, the QC knurling holder that comes with the HF QC toolpost set is pretty much useless. When you put any pressure on it, it happily loosens the clamping nut, relieving knurling pressure:-( Roy --- In 7x12minilathe@..., "rancerupp" <rupps@...> wrote: Gerry, others,

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....... regards gerry Leeds UK From: "born4something" <ajs@...> Reply-To: 7x12minilathe@... To: 7x12minilathe@...

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.

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.

You do a good job Chris, we'll allow you a little fallibility now and then !! ;-) Gerry Leeds UK From: "Chris Wood" <chrisw@...> Reply-To: 7x12minilathe@... To: <7x12minilathe@...> Subject: RE: [7x12minilathe] Re: Buying & Using a Knurler Date: Fri, 9 Mar 2007 09:18:42 -0800
OK, OK! The smaller knurler is now officially compatible with the mini lathe. When looking for the true meaning of deep questions like this, you guys have to factor in the fallibility of LittleMachineShop.com.

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

Looks like the scissor type wins out. I'll try to catch one on sale or do the ebay thing. Once I get it in, I may consider making my 2nd one (if further needs arise). Thanks for the input guys. --- In 7x12minilathe@..., "rancerupp" <rupps@...> wrote: Gerry, others,
