Thread: Loctite wheel to shaft
28/10/2014 22:50:39

OK, addition to my poat above: I found it! The trick was to search for tha author's name.

It is in part 6, Coatings

He shows 3 methods best is sandblasting, second the heating (bluing he says, so a bit hotter than what I wrote), and the third cleaning with some abrasive kitchen cleaner.

Have a look at these vids, this man knows a lot and even I am able to understand his English very well (something that's not always the case, unfortunately...)

Neil, that's an interesting question. I think I have seen the solution in one of Dan Gelbart's Youtube videos. There should be 18 parts, but on the selection on the right I don't see all. Someone knows how to find all vids of a certain contributor? (end of OT interrupt). So I can't locate it at the moment.

Well what stayed in my memory is the following: whatever solvent you use, after it has dried off you still have a one atom (molecule) thick layer of organic matter on your material.This can be proofed by trying to net it; the water will build 'balls' and flow off. The only way to get rid of that is to treat the parts with a flame from your trusty propane burner. Maybe to around 150-200 deg.C, I'm not sure about that, but after this treatment the water will adhere to the surface and wet it. A surface like this will also be netted by your epoxy/acrylate or whatever adhesive you use!

If someone is able to find this video I would very much like to hear about it again.

Part one is here: Gelbart

Thread: Gear Cutting Advice
02/10/2014 22:56:30

Hi Andy, my Leinen has roller bearings. I often think they would need just a little bit of adjustment, but I'm not able to understand how to do that. Also the two-speed clutch is shot and works only on the high speed side. Ah well, the oil in the headstock and especially the apron has the habit of disappearing very fast...

But nonetheless this lathe can still do precision work.

Not in UK, Switzerland it is...

Regards, HansR.

02/10/2014 12:35:24

Ah, finally a Leinen owner here! (although it's a LZ4S...). So we are two, almost a crowd then. laugh

My example was missing the (quite important) 90 teeth wheel, so I went the easy route and bought two standard gears, bolted and loctited them together and turned down to the thickness of the others - 15 mm you say. I'm sure one of the thinner wheels with a hub would be sufficient also.

Btw I use small polyurethane vee belts and a set of pulleys for the feeds - much more silent than the gears!

Bit OT, I know wink

Thread: How do i drill small holes - just ruined my Elmers Tiny Column :(

Instead of a standard spot drill you can treat yourself to a carbide centre tool from Eternal tools:

Not cheap I admit, but would solve your problems methinks. Satisfied customer etc., you know...

It would relieve you from learning to 'catch a centre' with a graver, an art in itself!

Kind regards, HansR.

Thread: LEDs ... The Good, The Bad, and The Ugly
26/09/2014 13:49:12

Not that it seems I'm not interested in that LED discussion. In fact I am, as a couple of these outdoor floodlights are under way to me. I hope they are bang good! Link seems to work very slowly, so have patience!

So may I propose that these LED discussions ace collected into a dedicated new thread? Nobody will find them again in this one...

Kind regards, HansR.

Thread: What did you do today? (2014)
25/09/2014 22:57:50

Changing the theme a bit... to what I did today.

made my first steps into anodizing. I'm happy to tell that it went quite well cool :

img_20140925_223645 (small).jpg

It might interest someone that I didn't use the usual 20 % sulphuric acid. Instead I prepared a mix of 2 liters distilled H2O, about 400 grams of PhMinus salt and 100 grams of liquid PhMinus. These two products are used for treating swimming pool water and are easily obtainable. I think the liquid is sulphuric acid, but only about 10%, and the cristalline is Sodium-Hydrogene-sulphate. I added the liquid form only because first I had no current flowing; later iI found out the culprit was the Alu wire I used for suspending the sample. I changed the wire to a Titanium wire and set for around 200 mA for this small item (with a lab power supply). I found a value of 10 mA per cm2 in the online literature, seems that's a good number!

The colour - is magenta ink for a inkjet printer! First thinned down, then I put a bit of the concentrated stuff on with a small paintbrush. Btw the dark spot near the hole is just a picture artefact

A couple of these famous (for anodizing) Dylon textile colours are already under way for the next trials!

Kind regards,

HansR.

Thread: Drilling stainless steel
23/09/2014 11:47:49
Posted by Doubletop on 22/09/2014 11:39:19:

Apart from doing a great job but a bit messy with it (easily cleaned up) I was told that if you drive RTD hard to the point it smokes it gives off a sulphur fumes which can cause rusting of equipment. So really a case of clean up well after the job is done.




Yes that's true, but 'rusting' is maybe a too strong word. The effect is more like that of the well-known blackening solutions, although the colour is more dark brown than black.

You can see this effect on a Morse taper holder for my Fehlmann Mill-drill, the exposed front part has got an even colour all around.

Thread: Not a "modeller"!

Posted by alan frost on 25/08/2014 21:38:54:

Got an idea. If someone could write an article for MEW on making model axes then someone else could write a little article on grinding them.

Too late, Alan. Has been done more than once, really... An example here:

Thread: What did you do today? (2014)
16/08/2014 23:58:12

Having seen an advertisement for a "Wimberley toolholder", I thought that I should try something similar. This toolholder is almost like a tangential tool turned 90 deg. anticlockwise. I admit the first version I did came out wrong, mostly because the point of the tool came out much too high when used in a quick-change holder.

So that's what my effort #2 looks like:

dscf0695 (small).jpg

dscf0697 (small).jpg

And does it work? Very well I think, although I have to experiment a bit more with the tool angles. Maybe I even will do a #3, but for smaller tooling. The 10 mm square is a bit overkill (and needs a lot of grinding...). I did a few cuts in steel, alu and brass, over 1 mm DOC is easily possible (but 0.01 mm also).

Thread: What drill bit for drilling 1 inch long 5mm hole through 10mm grub screw?
09/08/2014 11:18:22
Posted by Andrew Johnston on 08/08/2014 15:01:46:

I drilled and tapped a scrap piece of 6082 aluminium alloy with 3.4, 3.5 and 3.6mm drills, and then hand tapped the holes. I started off with a high tensile (12.9) SHCS in the hole drilled 3.6mm. The bolt broke before the thread stripped.

Any questions? wink 2

Regards,

Andrew

Yes. If you would check this M4 thread in the 3.6 mm hole with a go/no-go thread gauge, would it still pass that test?

Remembering from a dim past that I had quite often rejected jobs when the internal threads showed too much truncation. Some customers can be very sensitive...

Hi Jan,

I had a bit mixed feelings about what you described here, to be honest I can't imagine how the part you made looks in the end.

But one thing (well rather two) things I can tell you: You can't find M7, M9 and M11 screws/bolts because these are not used as fasteners! They are 'non-preferred' diameters, but that doesn't mean that taps and dies don't exist! There are even more such non-existing fasteners (every odd dia. from 11 upward); it would be crazy having screws every mm.

The other thing: keep off thinking that carbide drills would solve your problems! I bet that such a drill in your machine (whatever it is) would not last more than 30 seconds. It IS possible to drill all usual (for a mod,eng.)materials with HSS drills. Just today I did quite a lot of holes in 5 mm stainless, all with HSS.

Regards, HansR.

Thread: What pulleys to use for a milling machine and VFD.
06/08/2014 22:34:20

For motorizing the Aciera high speed head I would use one of the brushless DC motors, which are sold by Sieg. They include the control box also. I don't know the prices, but regarding the prices of the machines which use them they cannot be very high.

Regards, HansR.

Thread: Cupronickel as boiler material!
28/07/2014 23:03:07

There is a chap in Finland who builds all his locos from that stuff. Seems he can get it from a shipbuilding place,

Naturally this can only be done in countries where the profession of 'boiler inspector' is unknown laugh

See his videos here

Thread: turning tungsten
18/07/2014 21:55:57
Posted by Roderick Jenkins on 12/07/2014 21:28:13:

You're very welcome. If anybody has a source of heavy metal bar in small quantities I'd be glad to know of it. It's very good for balancing model i.c. engine crankshafts. 1/4", 6mm, 3/8" or 8mm would all be useful.


Rod,

that's not too difficult. Over the big water they indulge in a strange sport called Pinewood Derby racing. This has developed into a hi-tech affair, and so they use Tungsten rods and balls to put as much weight as allowed into these cars. Search for Pinewood, and you will see it all.

I also bought some small off cuts of Tungsten in 4-6 mm dia. (iirc) on this famous 4-letter auction site.

I did not any turning tests with these, but if someone asks...

Regards, HansR.

Thread: Which drill chuck to use for a Sieg C2 lathe ?
20/06/2014 11:47:03

Isn't a 16 mm chuck a bit too large for a C2? My largest chuck, for a much bigger lathe, is 12 mm.

Thread: WD40 alternative - any good?
13/06/2014 20:28:13
Posted by Neil Wyatt on 13/06/2014 19:58:53:

... But he impressed on me at an early age "WD40 is not a lubricant". ,,,,,

Neil


How true. I advise anybody who thinks that WD40 contains any kind of oil, take a sheet of white paper off your printer and put a splash of WD40 on it. It will get translucent, at least a bit. Now leave it for a day or two, and see what happens. You will not see the lightest remains, the paper is just as good and white as it was before. Repeat this with your preferred light oil and see the difference...

Before I forget: I use WD40 too, as a cleaner. For machining Aluminium I prefer the bespoke products of the trade.

Thread: white metal castings
18/05/2014 21:29:27

Speaking of White Metal - I made several efforts to obtain a small lump of bearing grade White Metal. Unfortunately all without success. maybe someone has a bit seasoning under the bench?

Also, would it be far away from the 'real' stuff to melt down a pewter mug or cup? Or getting the raw materials (Antimony, Bismuth) from Ebay is another possibility. Then one needs to get a composition...
