Thread: How I am wasting time
03/05/2022 10:39:28

Ah yes the ubiquitous safety sandals, the lack of PE makes me cringe. I saw one recently where a guy was welding and had a helper standing next to him, it brought back a painful memory. When I was young I did a holiday job in a small fabrication shop. Part of the job was to weld nuts on the ends of studs. I was the nut fitter and the welder was to my right. Woke up the next morning with sunburn on the right side of my face and arc eye. Looked like Richard Dreyfuss in Close Encounters but worse.

Here are two more videos.

Making a crankshaft https://www.youtube.com/watch?v=XsEIamdzsZs

I think the great thing about these videos is that they show clearly how things are done using basic tools.

Of late my consumption of YouTube videos has been far too high, might I be addicted? Anyway as they say a problem shared is a problem halved, here are a couple of videos I found enjoyable.

Thread: Use of a wild card symbol in the QBasic Chain command
27/04/2022 17:14:57

I don't really know Windows being a Linux guy, but googling "windows expand wildcards" lead me to this page https://docs.microsoft.com/en-us/cpp/c-language/expanding-wildcard-arguments?view=msvc-170#:~:text=Wildcard%20argument%20expansion%20is%20Microsoft,expanded%20in%20command%2Dline%20arguments.

You will have to find how to get the compiler linker to use the correct DLL

 

You could also look at using PowerShell which does support wildcard expansion.

You could try contacting the Guild of Leather Craftsmen.

They also have an advertising page https://www.guildofleathercraftsmen.co.uk/advertise-job-vacancies at the bottom is a section about equipment.

Thread: An ER32 MT5 collet holder
16/04/2022 17:49:10

Callum,

A backstop does not need to be accurately set, it just has to be accurately repeatable. Once the collet holder is in the spindle, backstop set and tightened down, it won't move.

To get an accurate length, face off the pice slightly longer than needed, then remove and measure the length. Now you know how much more to move the tool to get the length you need. Now every piece can be made to that length.

A small change to your design could be useful. If you drill and tap the M10 all the way through you would make it easier to tap and you can then screw the studding in to act as a back stop.

A backstop is not much use for cutters but would be very useful if you are trying to make small parts to repeatable length.

I know the appeal of making your own tooling, but did you know arceurotrade sells a MT5-ER32 adaptor

Thread: Before calculators
15/04/2022 11:39:28

I was educated after slide rules and before calculators so it was all meant to be done the hard way. I was taught about log tables and used those, plus my brother being that much older was taught and had a slide rule. He didn't need it so it became mine and I found out it was not against the rules to use one. I was the only one to use a slide rule in my entire year.

I can still remember buying my first calculator at Uni, still have it too.

Help! I must be doing it wrong.

Try Borax Substitute (sodium sesquicarbonate), mix it to a paste with water, rub it in and leave a while. Not as good as Sodium Hydroxide, but a lot safer.

I had a problem with a sticky yellow stain from cooking oil on my plastic mixer bowl, it was removed in minutes. It also removes the sticky yellow that builds up around the cooker.

Just looked it up https://www.planelogger.com/Aircraft/Registration/F-HBAI/685869

It is a https://en.wikipedia.org/wiki/Piaggio_P.180_Avanti

Belongs to Britany Ferries and seems to be the only aircraft registered to them, Perks of being the boss I guess.

Thread: condensation
13/04/2022 07:38:36

Instead of heating the cupboard, you could dehumidify it with something like this https://www.appliancesdirect.co.uk/p/md100/amcor-md100-dehumidifier

Just remember you will need to make the cupboard air and moisture tight. So plastic lined and seals on the door.

Thread: O rings
09/04/2022 08:34:34

Does your ram have guide rings? are they worn? if they are it increases the gap on one side which makes extrusion worse.

You could also look at the SKF DPV seals https://www.skf.com/binaries/pub12/Images/0901d196805e7f09-17145-EN-_Piston-seals_tcm_12-289553.pdf#cid-289553

Thread: Why is electricity so expensive?
07/04/2022 08:39:46

I was looking through the OFGEM graphs and there is a graph giving a breakdown of how the cap is calculated. https://www.ofgem.gov.uk/energy-data-and-research/data-portal/all-available-charts

What surprised me is that this year there was a 38% rise in Network costs, £268 to £371. Network costs are the allowance for the distribution, but why after being stable for years did it need to rise so much this year?

The cap rose by £730 but the Network Costs rose by £103, so 14% of the rise has nothing to do with wholesale costs!

Thread: Besler Steam Airplane 1933
04/04/2022 15:10:47

This video https://www.youtube.com/watch?v=AsgHKLRTp44 surprised and fascinated me. I had assumed steam had died out with the rise of the petrol engine.

Thread: Dulling the shine on a stainless steel ball

If you have a slow running motor you could try tumbling them with an abrasive. Or try electrolysis in brine, but be careful as Chlorine and Hydrogen will be released.

Thread: LED bulbs
24/03/2022 16:36:21

They really do not like heat and overheat easily. It is all down to the light fitting, plenty of ventilation is needed.

Also, to make things worse the cheaper or extra brightness ones drive the LEDs hard which shorten their life.

Google "Dubai Lamp" then next time you visit your Super Yacht in Dubi pick some up.

Thread: Warco BH600G - Motor hums but won't start
24/03/2022 16:18:51

I had exactly the same issue with my BH600G before I bought it. The short answer was a loose connection in the control box. After tightening all the screws on the contactors the motor started up normally.

First are you sure it is the motor, when applying power to the lathe, if all the safety switches are closed you get a clunk as the main contactor closes. No clunk then a safety switch is open. There is a small hum from the 24V transformer all the time.

If I remember right (ref pg 65 of Grizzly manual) the problem was the overload contactor FR had worked its way loose from KM1 (top left)

FR hangs under KM1 and is held in place by being screwed into T1, T2 and T3 on KM1.

In normal operation K3 (top right) closes, then for Fwd/Rev KM1 OR KM2 close. For testing, it is possible to push the centre of KM1 OR KM2 and start the motor.

The motor has connections U1, U2, V1 and V2. In the control box U1 = Neutral and on KM1 T1 = U2, T2 = V1 and T3 = V2

When running Fwd

U2 = Live

V1 = Neutral

V2 = Live

When running Rev, V1 and V2 are reversed.

U2 = Live

V1 = Live

V2 = Neutral

BTW It does not like starting from cold at a high spindle speed, releasing the belt tensioner lets the motor spin up to speed first.

Hope it helps

Adrian

Thread: Changing my Email client

I used to use Thunderbird and found it very good, but now I just use the web clients for Outlook and Gmail. That way I get access on any device, assuming I remember the password.
