Thread: Buying a mill - What basic Toolkit?
29/10/2017 20:30:44

One of the additional "bits" that I bought with my mill was a set of ground parallels

**LINK** (usual disclaimer)

I have found them most useful for all sorts of setting up, both in a vise and on the mill table. A bit of an outlay but I wouldn't be without them. Not an everyday use item but certainly often in use.

Thread: English dialect
15/09/2017 00:47:49

My late father who was raised in Motherwell had quite a few descriptive phrases in his vocabulary that originated from the work that he and his father did in the Lanarkshire Mills in the 1920s. Eg. if the materials at hand for a particular job were of a poor quality he would refer to the inferior materials as being a poor scantling of....

His name for an awl was a mennie.

Some of the more colourful descriptions he bought back with him were of people he met. Among those were descriptions of people who had : a nose like a gimlet, shoulders like a lemonade bottle, or a face that would turn a funeral.

Then the PC cops arrived and we all got to speak real proper.

Thread: DIY Magnetic Chuck

An interesting project but I don't like their pricing system.

As I understand it and I may have mis-read it, you need commit to subscribing $10+ a month to get the plans. No mention of how long for.

I wonder has anyone on the Forum tried to build something similar?

Thread: Westminster Attack 22 March 2017
24/03/2017 01:04:02

I feel a real sadness that ordinary people following their ordinary lives should be the victims of senseless acts like the Westminster atrocities. Many lives cut unnecessarily short and no doubt many with long lasting injuries.

I must however agree totally with Blowlamps posts above. Many Western governments do not have clean hands here. Their actions give an excuse to religious fundamentalist groups to follow their agendas.

History shows us that religious fanaticism has killed more people since the dawn of history than practically anything else. And that stretches across all denominations!

That fanaticism draws many "hangers on", and one would suspect it gives many of lifes "no hopers" a chance to fame in their own mind, in carrying out some spectacular action no matter how senseless it might be.

There are luckily not many so deluded and we must all be careful, keep a cool head and preserve the freedoms that our society gives us.

Thread: Cheap chucks from ebay.
15/02/2017 20:33:37

Alastair,

I'm not sure if a spare no. 3 from another similar Burnerd chuck would fit without centring issues. Maybe some of the experienced members on here could advise.

The reason I ask is that I have a spare no.,3 which came with my Bantam lathe. I most likely will not use it and if solves your problem then you are welcome to it.

I have put a few pics in one of my albums.

Chris,

Personally I have found books ok to browse But by far and away the best tuition I have come across for between centre or spindle turning is:

A master of his craft and a good teacher as well. Worth playing and replaying.

Hope this helps,

Thread: Electronic mouse trap
10/01/2017 17:37:05

Apparently, the enamel on a rat's tooth is the hardest organic material known.

A friend who worked as a Health Officer had an interesting story about being called into a turkey farm that was plagued with rats. The owner had tried everything, as did my friend, but the rats were thriving.

After quite a bit of head-scratching he checked into the contents of the turkey feed. They were adding a vitamin supplement (K, I think) that was the perfect antidote to the poison.

Having sussed that and removing the vitamin, the rats were beaten!

So don't leave the cornflakes laying around.

Thread: Metal cutting bandsaw
04/01/2017 22:43:59

Whatever you do, steer clear of one of these, sold under various brand names. Mine was WoodStar.

img_3523.jpg

With space issues. I searched widely and found that these had been converted to a table mounted saw by at least one respected member on another Forum. So, I got one. It comes as a portable saw with no mounting system for table use.

I went to considerable effort to fabricate the yellow and grey hinging mechanism seen in the photo which was problematic, added an auto cut-off switch, got good bimetal blades and was very pleased that I had a light portable saw. However, within a short while blade tracking became a problem. I added extra guides. Eventually the blade slipping off chewed up the wheel-bands and driving wheel and the saw became unusable.

img_3524.jpg

Annoyingly 90% of the saw was reasonably well made but they had fitted PLASTIC wheels, which began to flex........It was directly gear driven from the motor with one gear moulded into the plastic wheel so not easy to remedy. The ha'pworth of tar syndrome.

So you live and learn. I now have a second-hand Clarke model CBS45MD. I have done enough mods and fixes on it to write a whole chapter. It cuts straight and square in both planes and is a great addition to any workshop.

I hope my experience might save others from wasting their efforts on this type of machine.

Thread: Scrapping an Electric Cooker
02/01/2017 14:57:58

Hi Silly Old Duffer,

I'm coming 67 soon and to prove it have two small sheds lined with "might be useful" bits in boxes salvaged from dumped or broken items. Like yourself I'm an incorrigible fixer..but... I can honestly say that over the years only 2%, if that, of all that was ever rescued was found to be useful for my projects. Maybe I'm not creative enough but it is generally more trouble than it is worth to "Make things fit". The main exception is machineable lumps of metal.

One little triumph does come to mind though. One Christmas Eve the pump on the washing machine gave up and with everyone off work and three young kids and a fretting Mum in the house I had a little root around in the local dump. You could do that then. A useable pump was found and Christmas was salvaged and the old machine ran for years after.

My new Year resolution is to tackle the clutter. Ask me in Dec. how I got on.

Thread: An unusual thread...maybe

That was quick! Thank you all for your help. Much appreciated indeed and problem solved.

Best wishes to you all for Christmas.

A friend of mine was rebuilding a 3" marine pump and the technical spec for the thread on one end of the drive shaft specified a thread which was described as G3/4A, that is G threequarter A, with a major diameter of some 26mm.

Not one we came across before and 3/4" being about 18mm we were a bit puzzled. It seemed to be about 14TPI.

Can any knowledgeable person on the forum give me any information as to what we might be dealing with please?

Hi Daniel,

It would help if you posted additional info and maybe a photo.

Physical size, wheel size, motor output and the type of mounting on the brush side etc, would help contributors on the forum to advise you.

Thread: Purchasing a Milling machine
13/11/2016 22:48:44

I have had an Amadeal LV25 for a few years. It has not given any real problems. It can tackle light to medium jobs but don't expect to take heavy cuts. With light feeds and plenty of cutting fluid it will chomp away at it's own pace.

The only black spot is with the fine down feed. There is a lot of backlash in the knob. I have not managed to eliminate that as it seems to be the mesh of the two gears. Amadeal were willing to investigate it but needed the machine back. As I only live 200 miles across the sea and can't swim I have learned to live with it.

Like a lot of Far Eastern machinery, it is advisable to strip it down to clean thoroughly and re-lubricate. There are plenty forums on the Web to explain how and there are some useful mods you can make also.

You're going to need some sort of clamping system and /or vise also. I found a set of parallels very useful in setting things up. The list goes on.

My own feeling is that if I were buying now I'd go a bit bigger, but at the time it got me into the hobby and If I'm honest it will, with patience, do most of what I need.

Thread: Hand scraping
30/09/2016 23:03:15

This is a very informative discussion indeed!. Thanks to those who shared their knowledge.

A relevant question then. I had reason to straighten a gib strip on the lathe cross slide recently. I stoned it flat and matched it to the opposing face with blue.

Should the face of the gib strip have been scraped with any kind of pattern to hold oil on it's surface or can it be left flat?

Thread: What would you ban and why? (Definitely tearoom!)
24/08/2016 21:23:42

I'd ban the latest Americanism that seems to have crept in where in interviews every reply has to begin with "So...".

Thread: Borescope
17/06/2016 23:56:48

Chris,

I have one of those scopes.

I had the same problem until I realised that you needed to change the setting on your computer which dictates to the computer which video input (camera or scope) you want the computer to use.

There will be the original built-in cam that is the default one.

You have to change that setting to tell it to use the borescope. It is a while since I used it but I remember it was simple once I copped what needed doing, and the video quality was quite good.

Thread: Fixing a drill chuck
01/05/2016 20:48:53

David,

Try this for info on dismantling etc. but really on a new chuck you'd be wiser to demand a working replacement. If you tamper with it and it doesn't cure it they won't take it back.

Thread: Carburettors!
30/04/2016 00:10:29

Wolfie, those three innocent looking questions can have very complicated answers.

To keep it simple, and hopefully not simplistic, an engine needs a supply of a mix of c.16 parts air to 1 part petrol for normal running. There is normally a large hole through the centre of the carb where this mixture is created. The air comes from outside through an airfilter and the petrol is fed in through small holes called jets. These jets can vary in size of the orifice and from small to large of course supply varying amounts of petrol.

A simple carb has the jets or orifices calculated in the factory and they cannot be varied. eg many cheap lawnmowers etc. They are calculated to work well over a fixed speed range.

A step up from that on machines which need to operate on a wider speed range will have a basic setup to control the mixture at three critical points ie. at starting from cold, then at tick-over (or idling speed) and lastly at full open throttle.      At tick-over a small Idling jet feeds out a small amount of petrol into the airstream. This can usually be adjusted by means of a tapered pointed screw, the nose of which can be screwed into the little hole or jet to increase or decrease its size and consequently the flow of petrol that it delivers. Generally called the idle/ mixture screw, you set it when the engine has warmed up to normal operating temperature. Once set you usually leave it alone.

So until the engine warms up another scenario prevails. A cold engine starts better on a rich mixture, ie. more petrol in the air/petrol mix. To achieve this there is often a flap of some sort called the Choke which restricts the flow of air so the mix going into the engine drops to maybe 10 to 1 for starting purposes. As the engine gets going and warms up you would reduce the choke amount and after a few minutes the engine will run on the idle jet as above.

The third state of running would see the engine at full speed and running on what would usually be called the Main jet. This is usually the one you find sticking up slightly into the mail hole through the carb. To vary the amount of fuel drawn through the main jet there is often a tapered Needle that is set with its nose partly inserted in the main jet orifice. The more this needle is inserted into the main jet, the smaller the opening and vice versa. This needle is controlled by the accelerator cable and can be raised or lowered by the operator to increase or decrease the flow through the Main jet and thereby regulate the speed of the engine.

To get quickly from running on idling speed to running full speed there is often as Clive states, an accelerator pump that gives a little squirt of fuel that helps things along.

There are many refinements and adjustments on the above. A good source for more detailed explanation is:
