In theory it should be possible to dissolve ball-point pen ink in the same way. In practice, more trouble than it's worth!

Cheers Dave will try some when I get a chance

It is easy to make a marking out blue as follows: Take 50 ml of French polish and add 50 ml of methylated spirit. Now take a cheap blue ball point pen and pull out the nib and ink tube. With a pair of sharp scissors chop the ink tube into pieces about 12mm long and let them drop into the mixture of French polish and alcohol. Shake the mixture and leave to stand for a day. The mix is easily applied by a small brush and it is quick drying. It marks easily with fine scribe. It is resistant to water based and oil based complaints and cutting fluids.

Thread: ALDI 3D Balco printer
29/05/2019 10:24:04

I bought the Balco printer from Aldi before Christmas 2018. It worked straight out of the box and I have used it to make various workshop related items such as gears, vee beltpulleys, timing belt pulleys etc as well as some household items such as sonic tooth brush stand, camera lens cap, a small bin to fit the cupholder in the car, sat-nav holder etc.

I find it a very useful addition to my collection of workshop tools.

Thread: seals for mini lathe tapered roller bearings?
01/04/2019 21:42:24


I do not remember having to do any work on the end caps, but it was 6 years ago. I will have a look tomorrow and give you an update.

There is a possibility that a 48 x3mm O ring could be used if the external cover was adapted a bit more - not a seal as such, but would minimise the gap on the external faces and help keep out coarser muck.

This is the approach that I used when I did my taper roller conversion. I figured that at the very least the o-ring would act as a thrower ring and prevent oil and swarf migrating along the spindle shaft. I did the conversion at least 6 years ago. Every year I remove the plastic endcaps and inspect for debris. I have never found anything after the o-ring.

Gee Neil

You are really kicking goals with your astro imaging, I am in awe of the images and the work you need to have done to get them.

What I am in awe of is that Neil holds down a day job, edits MEW, writes books, spends time in his workshop, is very active on this website and he still finds time to sit outside at night staring at the stars!!!! Amazing.

Thread: Balco 3D Printer
27/02/2019 22:13:04

My Balco printer, the same as the current offering from Aldi, has a very firm steel frame and is already equipped with a cooling fan on the extruder. I have had no problems with it straight out of the box except for the levelling screws on the print table being a bit loose. This problem was easily solved by printing some washers that fit under the springs of the levelling screws.


Thread: Motor for a Sieg X1 mill or (M1 attachment)
07/02/2019 11:27:42

I just remember seeing this:

This is a powerful;motor, 500W, and variable speed power supply already assembled at a cost of £120

The motor that you picture on the Clarke milling attachment to the C1 lathe looks identical to the motor on my X1 mill from ArcEurotrade.

Since it is unlikely that you would need to use the milling spindle and the lathe spindle at the same time I suspect that the attachment does not have a separate power controller board and that it is run from the same controller as the lathe motor. Is there a socket on the back of the C1 that the attachment plugs into?

I would urge you to consider making a belt drive conversion rather than replacing the gears in the mill headstock. The belt drive is much quieter, smoother and reduces any shock loading on the spindle. It is sudden shock loading that tend to upset the controller board. My belt drive conversion on the X1 mill is shown here:

As an alternative motor you may be able to pick up a small dc motor that was made for an electric golf trolley. Ebay usually lists some of them. This could be used with a 12 V motor controller from Ebay


Thread: Cheap 3D printers
07/02/2019 11:04:13
Posted by John C on 19/11/2018 17:05:09:

I have several Aldi hand and power tools, all of which do 'what it says on the tin', but are not pretending to be high-end products. With that in mind, what would the forum think of this:


I bought one of the ALDI printers and I am very pleased with it. The only problem that I have had is that the springs on the bed for the levelling screws are too short and they do not hold the bed in a reproducable position. I 3D printed some spacers to fit under the springs and everything is better now.


Thread: Super glue filler
26/01/2019 20:36:52

Small hollow glass microbeads used to be recovered from the flyash of coal-fired powerstations. They were known and markerted under the name Armospheres. In the match industry they were used as a way to control the density of the match composition applied to the end of the match stick. I guess with the demise of coal fired power stations they are less available than they used to be.

Thread: Mini Lathe Rear Tool Post
15/12/2018 19:34:53


I made a rear toolpost for my minilathe, see:

Before making the toolpost I had already made a tee slot cross slide which was considerably longer than the standard cross slide.

The tee slot provide a ready means of attachment for the rear toolpost but I think the rear toolpost could be attached directly to the cross slite it a hole were drilled and tapped .

The big problem that you will have using the standard cross slide is there will be little distance between the front toolpost and the rear toolpost and this will limit the size of work that can be turned. If you are only making small parts than maybe this will not be a problem.

Perhaps the cross slide could be extended back by bolting a piece of steel plate to the top of the cross slide that overhangs the back. The rear tool post could be mounted on the overhang.

I hope this is useful


Thread: Blackening steel parts
28/11/2018 18:13:26

There has recently been an interesting posting on the HSM forum for blackening steel using ammonium nitrate. This seems to avoid most of the complications and dangers associated with normal hot blackening baths. see:

When I have obtained the material I intend to give this process a try.


Thread: Non-Ferrous Casting
23/11/2018 18:13:26

I regularly make lost foam castings by just burying the foam in loose dry sand with a foam riser protruding above the surface. No need for greensand or venting.
