Thread: What to blacken steel with
18/01/2020 06:00:04

Hi Steve,

You can buy so called cold blacking solutions for steel, a friend of mine has tried and it works. I just heat the mild steel parts to about 270 to 300 deg. C and apply linseed oil, the treatment will to some degree protect against corrosion. Others use motor oil. The treatment is best done outdoors.

Thread: Windows 7 support ends
15/01/2020 11:36:20

Hi Windy,

I'm running Windows 7 on my old laptop using Avast antivirus and Firefox, no problems so far. Whether your old programs will work under Windows 10 will probably depend on what programs we are talking about. On my new laptop (with Windows 10) I have managed to run most of my old programs from the Windows XP era.

Thread: To use chuck or collets
10/01/2020 11:16:03

After I made an ER-32 chuck for my small lathe it get used quite often, if I can use the collets I prefer them instead of using my 3-jaw. My cheap Chinese collets have slightly more run-out than my Vertex collets, so when I buy new collets I try to get Vertex ones.

Thread: Machine reamers
08/01/2020 17:51:42

Hi Matt,

I assume you are looking for reamers like these, imperial sizes I guess.

ArcEurotrade has chucking reamers - both metric and imperial.

Hi Chris,

May be this can be of use; Chapter 3 (page 25 onwards).

Thread: Temporary oil conundrum
17/12/2019 06:06:19

Hi Mark,

Use mineral based Chainsaw oil or engine oil for the temporary oiling. The chainsaw oil sticks to the surface so would be Ok for the vertical ways.

I would not recommend that you use 3 in one, rapeseed oil or olive oil.

Thread: Run outs
10/12/2019 13:46:28

Hi Raphael,

I guess it depends on how fast you run your chuck and how accurate your work needs to be. If your Chinese ER chuck has a run out of 0.01mm, I wouldn't complain. I just bought a cheap Chinese ER-16 chuck and it has slightly more run out than yours. The cheap ER collets I have says max run out 0.015mm.

Thread: Old Lathe Lubrication - oil through a grease nippled?
08/12/2019 15:12:19

Hi Peter,

Not sure I can answer your first question, I just use an oil can like this, if there leakage i put a small piece from a paper towel between the nipple and the oil can spout. This has worked well for several years. For lubrication of plain bearings I just use hydraulic oil (ISO 32).

Thread: Toolpost dilemma

Hi Lou,

There are people who have made their own toolholders for the Dickson type toolposts (may be a bit more difficult to make than the Aloris ones):

Thread: Any users of the 'ModelEngineersUtilities here?
04/12/2019 06:31:11

Hi Hans,

Your screenshot is exactly what I experience on my W.10 laptop. Here's a screenshot when running Win.XP:

me_utilitiescs.jpg

The program works well under Win.XP, and I have tried to tell W.10 to emulate Win.XP when running it, but it still looks like your screenshot. So I have not been able to find a way around the problem, may be others with more computer knowledge can help.

Hi Hans,

I have tried the ME Utilities program on my W.10 computer, I unpacked it as Administrator and tried to run it as Administrator and the main screen pops up without problems, but when trying for instance the "Speeds" part I too get the black backgound and buttons not doing anything. The screwcutting part seems to work OK, so mixed results on my new computer. When I find time I will try it on my old computer running XP.

Thread: New to model engineering - what solder / flux and annealing question
29/11/2019 05:26:59

Hi Charles,

I anneal copper and brass by heating to dull red using a propane torch in a makeshift hearth. As for cooling, it depends. Cooling in water may cause the part to warp, so for more complicated shapes I let it cool slowly in air. Usually for simple parts I just dip the part in a bucket of water.

Thread: My week this week! My workshop videos
22/11/2019 18:28:15

Hi Phil,

Thanks for the photo, yes, smoke can be irritating. I am no blacksmith (or knifesmith) but I occasionally do silver soldering and just use a few firebricks to make a temporary hearth outdoors. I have to wait for nice weather, which you don'tsmiley.

Thread: Precision Tool Vice Type 2
19/11/2019 04:52:25

Hi Phil,

I have a Type 1 vice from Vertex and I have had no issues with mine. Type 2 is slightly different, a photo of the underside might be an idea.

Hi Phil,

I wish I had a forge like yours, unfortunately my workshop is too small to make room for one. Thanks for sharing.

Thanks for the tip Chris, I must check if it is possible to do the same on my milling machine.
