Thread: Rust Protection
27/01/2022 17:00:08

I use this to protect my machine ways, Inox MX-3.

A friend who owns a very expensive ocean racing yacht advised me many years ago to try this, so after a machining session I give the ways a spritz from a spray can and so far, not a trace of rust in 15 years.

It's also handy for machining aluminium if one runs out of kero

Why Lanolin? I recall using it as an apprentice to protect measuring instruments in the metrology department.

I guess if it keeps sheep dry, it must have something going for it.

Yep, lanolin is excellent for protecting bare steel.

Thread: Lapping in a lathe
27/01/2022 03:11:17

G'day all.

I have used my minilathe successfully to manufacture a few pistons and cylinders for my model engines over the years.

Now just setting things up to restore an ancient ME.Snipe by boring and lapping the liner to round and them machining a new piston from cast iron and lapping it to size I began to wonder about the effect of the stray lapping compound on my lathe.

The bedways I always cover with cardboard, so I was wondering about what happens to any lapping paste that strays into the chuck?

Current lapping compound ranges from 1000 - 4000 grit, carborundum though to jewellers rouge. I am contemplating using diamond lapping compound to save time but it is a PITA to remove from the components and I am only contemplating using this substance as I have an ultrasonic cleaner.

A lathe chuck is a bit big for my ultrasonic cleaner.

Maybe I am overthinking this (always dangerous for me)

So, over to the experts.

Thread: Is it possible to by "100% non-stick" spatulas for spreading glue? (ideally made from teflon/FEP)

Hello

Is it possible to buy a spatula made for Teflon (or something similar that is totally non-stick) for spreading glue?

Thanks

J

Actually, you might want to consider what the English Ashes team use to coat their gloves with as nothing sticks to that.

I heard that Novac J is being considered as a batting coach for the English cricket team as it took almost two weeks to get him out.

For spreading epoxy, nothing beats an old credit card.

Thread: Are you going to buy a milling machine
25/01/2022 06:18:01

G'day Stevie.

I found that whatever one purchases a lathe or mill for, a decent set of tooling and accessories to suit can double or even triple the initial cost.

Thread: C3 Minilathe Electrical Fault - Fixed
23/01/2022 08:23:22
Posted by MikeK on 23/01/2022 01:40:38:

I ran into the same problem when I relocated my fuse holder from the side to the front of the control box....It crumbled. I don't even like the location of the control box as I have to remove it to get up close to the spindle when I use my 3MT collets.

It appears that the original material is not stable over the years as your report confirms.

The replacement parts that I installed are made from a phenolic material and the data sheet indicates that they are made to a decent standard.

One thing that I had to do was to make a new 'flat' opposite to the original one. After wasting time with a file it turned out that a small drum sander in a Dremel rotary tool soon did the job. Alternately, one could re-shape the hole in the plastic control box housing as it is very soft and cuts easily with a sharp hobby blade.

Mini-lathe is now running smoothly, all lights,switches, tacho and controls operate as they should.

I have not re-fitted the lead screw yet as while it is out I plan to take the opportunity to drill the lead-screw pillow blocks and install some 6mm oiler fittings that I purchased a few years ago to pad out another order. 6mm oiler to suit mini lathe and mill

Just a question for anybody who has used these oilers, does one pack them with a wick/felt or just use them as supplied?

Another update.

I decided to remove the control box from my C3 minilathe to better undertake and inspect the repair work (soldering).

As a qualified electronics maintenance engineer it might seem a bit overboard to some, but I was trained that way.

After tagging the disconnected wiring another potentionally dangerous fault was discovered when I noticed that the green 'Power On' indicator had no source of illumination.

I discovered the remains 'hanging free' inside the control box. also of note was that the attached wiring was hard and noticeably heat affected

The plastic housing had also deteriorated just like the fuse-holder, so it had also broken and detached from the minilathe housing and as this is a neon indicator it also carries 240V.

As a safety issue I advise that anybody whom owns an ancient minilathe to inspect the relevant components and replace them if required.or get a qualified person to inspect them.

Thread: Parts storage
21/01/2022 05:22:51

G'day.

I am not biased because this is an Aussie product. It just works as advertised!

Inox and Lanox

I have been using these products for over 20 years to prevent rusting of all my tooling and model engines.

My C3 Minilathe and X2 mill are still as rust free as the day that I purchased them many years ago, I just give them a spritz at the end of a working session and whether I return the next day or the next month or two they are just as I left them..

The best part is that they don't dry out. A bonus is that Inox MX3 is a great cutting lube for machining aluminium alloys if one is temporarily out of kero.

A wipe with Lanox over seldom used drills, cutters and reamers before storing in a ziplock bag has stood me well over the years, never a rusty part.

A friend who owns a large ocean racing yatch advised me about this product when we were flying model seaplanes in 1999 as it is his 'go-to' corrosion inhibitor in the extreme environments in which he races.

Available worldwide too. (No I don't own any shares in the company) angel

Thread: C3 Minilathe Electrical Fault - Fixed
21/01/2022 00:31:57

Just an update.

I located a decent quality fuseholder that fits perfectly so ordered qty 2 as I decided to replace the one in my X2 mill in case it suffers the same fate.

If the active wire had fallen across the control board or the leadscrew it might have been quite serious.

The replacements that I ordered arrived overnight from Sydney, NSW which was pretty impressive in these current times (I live in Victoria).

If anybody is looking for a replacement fuseholder The RS Components part # is 188-4630

Was the minilathe new to you?

Minilathe was purchased new in 2006, it even came with a spare M205 3.15A 250V fuse.

Actually; it was instructional to look inside the control panel housing as the lead screw traverses though it and I wanted to see whether my home made swarf guard had worked over the years.

The swarf guard was lid of a 35mm film container which enclosed a disk of felt (from an old hat) with a hole a bit smaller than the lead screw diameter and which was secured to the outside of the control box using neutral cure silicon adhesive.

It was pleasing to observe that only one or two tiny brassy looking flecks could be seen.

Also made a mental note that the lead screw bearing blocks deserve a bit of a clean and lube.

Actually my biggest problem is locating a decent quality replacement M205 fuseholder. Diameter is 13mm, it also has anti-twist flats across the threads. I found a few candidates, cost about $4, shipping $10 -$15 ; -)

Such is life.

G'day all, just back after my gap year.

Today I set up a job in my C3 Minilathe and when I hit the power switch, no lights.

Checked the mains power socket, all was well so uplugged everything and decided to check the fuse,

When I unscrewed the fuse holder, it slipped out easily, but no fuse in sight.

So to cut a long story short, after removing the lead-screw and opening the electronics box I discovered the fuse sitting in the bottom of the box.

Next I spotted a black wire hanging loose with a silver contact soldered to it and closer examination revealed that the rear of the fuseholder had broken away from the body.

When I removed the broken fuseholder, many other pieces of the plastic body crumbled away.

The C3 is 15 years old and I have never had any electrical failures before.

The fuse is not blown, so I can only conclude that the plastic used for the fuseholder has deteriorated over the years. The Minilathe operated fine when I last used it in November.

At the end of the day I am relieved that it was not a more serious fault with the control board so I decided to post it here in case anybody else has a similar problem.

Thread: Censorship on this forum
19/02/2021 11:53:55

People, this is nothing to do with politics, it is to remark that facebook have blocked many Australians from vital services such as bushfire, floods and covid updates as well as protection services such as domestic violence websites, Facebook in Australia

Next it might be you. All because they were asked to pay for content that was plagiiarised from Australian websites.

I have no idea why my original post was blocked but common sense seems to have prevailed.

I thought that was what the Tearoom was all about, to comment on non model engineering matters that might affect us all and facebook prying into our private lives sure fits the bill for a bit of discussion.

19/02/2021 10:51:39

So I just tried to create a new thread in the Tea Room about facebook blocking Australian subscribers and it was deleted by an unknown moderator.

Is censorship of fair dinkum topics now banned?'

Maybe this message will also never see the light of day so to the forum police I must bid you goodbye and well done to shut down free speech on this great forum.

... I am wondering if there is anything electrically heated, that might run off a pair of [say] 4,000mAh USB ‘power banks’

All serious suggestions welcome ... and the silly ones will be tolerated.

You could consider moving to Australia Michaell. After 14 days quarantine and a little jab the cold would be the least of your worries.

Lathe and mill parts are expensive but the locals are very friendly

Thread: How Many People Does it Take to Change a Lightbulb on the Forum?
18/02/2021 07:22:53

I always thought that lightbulbs and other electronic components ran on smoke and if one let the smoke out they failed to work. This is based on experience.

Of course, on this forum the lightbulb followers would be up in arms if the forum software were changed and the lightbulb questions were not displayed with a light grey background with olive green post separators with ads that flicker like a failing lightbulb scampering down the right hand column.

Of course, the discussion might gravitate to why change the lightbulb in the first place?

Not required if one had purchased one of these Worlds longest burning light bulb It still has all the smoke intact.

Oh dear, it appears that all PM's are lost in the change to the new software, so time to back them up now. Mail lost Given the photo album issues I just moved all my albums to more secure storage (my pc)

One bonus is that Adblock Plus get's rid of all the pesky ads between posts. Sponsors would be not amused .

If I wish to purchase something then I shall search for a vendor and not have ads forced on me, this is a definite turn off from pushy sales people.

The Barton site is ad free, it just relies on the members to top up the pot and it works surprisingly well Site Funds - Scroll down left column
