Thread: Making a Start in FreeCAD
20/06/2019 12:34:32

Following Dave's excellent tutorial I tried to make a model of something useful, a tray for my ER 16 collets. A friend of mine has access to a 3D printer where he works. I haven't tried printing the model as my friend is on summer vaccation.


I have tried to write an explanation of what I did here, probably many errors so I assume I will have to revise it.

Hi Kiwi Bloke,

I am trying to understand FreeCAD and have found a few tutorials that you may find helpful:

Thanks Dave, will be following with interest.


Thread: Precision Metal Pen Oiler
18/06/2019 13:44:56

Hi Jim,

Those Pen Oilers are very handy, I have had mine for many years and use it when I need to oil my model steam engines.


Thread: Lathe Speed - What am I missing out on?
18/06/2019 05:17:16

Hi Jim,

On my old lathe I do adjust the belt to get different speeds, low speed when turning large diameter jobs since I get more torque and high speed when turning small diameter jobs or brass/alloy to get the job done a bit more quickly.

Hi Gray,

Congratulation, excellent job as usual. I'm impressed how you have managed to fit it inside the rear cover.


Thread: Carbide inserts tool holders.
16/06/2019 05:36:06

Hi Dave,

On the few holders I have come across I was able to mill the holder down using a carbide tipped cutter, would probably be possible with a HSS cutter but the edge might need grinding afterwards.


Thread: Material storage fpr Lathe/other machines

Hi Robert,

A very nice solution, and as Bazyle says, that is a clean and tidy workshop.


Thread: New vice, good choice?
11/06/2019 18:00:14

I have got two screwless vices and are very satisfied with mine. They are not to large for my milling machine.


Thread: 4 jaw chucks
10/06/2019 06:04:25

Hi Arckivio,

When I installed a smaller 4-jaw independent chuck on my small lathe I already had a backplate with the correct register diameter, but with 3 mounting holes. So I simply put a mounting bolt in one in one of the holes in the backplate and used one of the 4 holes in the 4-jaw, then I could use the backplate as a drilling jig to mark the position of two new holes at the back of the chuck and drill and tap those two holes. Saved me some work and time, I agree 4 bolts would have been better but a couple of the holes would have interfered with the bolts that mount the backplate to the lathe mandrel. It has worked well for several years.


Thread: Cardibe inserts
07/06/2019 13:09:17

Hi Dave,

Some of the inserts I have has a small hole in the centre, they are intended for holders with a short pin on the underside of the bridge clamp (see Ian's post), the pin prevents the insert from moving when taking heavy cuts (well, so I was told when I bought the inserts). May be yours can be used in a similar holder.


Thread: Coolant Flow Rates
06/06/2019 13:15:00

Hi Nigel,

I too usually turn and mill without using coolant. When using HSS tools without coolant I run at a somewhat slower speed than the tool manufacturer recommends as their speeds are for industrial machines with flood coolant.


Thread: What are you using for Lathe Way Oil?
02/06/2019 11:48:20

I too use ISO 68 way oil since a friend gave me a 4L can, before that I used mineral based chainsaw oil mixed with a plain ISO 68 oil. The carriage seems to move slightly more smoothly using proper way oil.


Thread: How often do you oil your lathe ways?
01/06/2019 06:23:19

I do pretty much the same as Hopper do, lubricate the ways at the start of the session, afterwards I clean the ways and add a few drops of oil.


Thread: Do you wear a mask grinding HSS tool bits?
28/05/2019 13:10:38

I have to admit that I don't wear a dust mask if I'm only touching up a tool, as Neil said. For grinding a HSS toolbit to shape I wear a dust mask. Inhaling a lot of fine dust particles isn't healthy.


Thread: Replacement Type cross slide nut.
27/05/2019 04:37:49

Nice work David, did you back off the cutting edges of the tap?


Thread: Service received
26/05/2019 06:34:39

I too have ordered metals from M-Machine several times and have always been satisfied with their service.

Thread: Childhood diseases
23/05/2019 12:50:22

Hi Danny,

You can get measles outbreaks in areas with low vaccination coverage, for instance from non-vaccinated visitors, and vaccination causes less trouble than getting measles. If you are vaccinated or had measles as a child you should be well protected. A high vaccination coverage against childhood diseases is an effective way of preventing outbreaks.

Thread: Mini-Lathe setup for an absolute beginner?
21/05/2019 13:45:44

Hi James,

Welcome to the forum.

1. Many model engineers use a Mini-Lathe for their work, so I guess it might be sensible for you to buy one.

2. I have bought several items from ArcEuroTrade and have always received excellent service, I don't think
you need to worry.

3.Brushless motors should be Ok.

4. The older Mini-Lathes with a brushed motor sometimes had controller problems. I have an old Mini-Mill
(same brushed motor and controller as older Mini-Lathes as far as I know) that is over a decade old and
have had no problems.

4. I live in a country that adopted the metre convention in 1875 so I would say a metric lathe, others may
have a different opinion.

5. For cutting aluminium and plastic HSS tools should do Ok, I myself use both Carbide and HSS tools
depending on the job at hand.

I am old and have back troubles so I wouldn't carry it up a flight of stairs alone, I would ask a friend to assist me. Good luck.


Thread: Potty Mill engine materials list wanted

Hi John,

I can't remember having seen a materials list (someone else will probably point you in the right direction), but there is a Parts List on this drawing set.
