You could try a bit of PEEK, a plastic which can stand temperatures up to 220°C and a melting point of 343°C.

Continued from previous post.

The storm also disrupted the electricity supply, the telephone network and the railway service. Many people had to be rescued by the fire brigade or the police from their flooded properties or vehicles. Fortunately, there were no fatalities or serious injuries reported, but many people were left homeless or without essential services.

The storm of July 14, 1981, was described as a “once in a lifetime” event by some meteorologists, who compared it to the Lynmouth flood of 1952 or the Boscastle flood of 2004. It remains one of the worst floods in Birmingham’s history.

I gave Bing a try-out about this storm. I asked about a severe rainstorm in Birmingham around 1980. It responded with the following...

It happened on July 14, 1981, when a record-breaking 58.2 mm of rain fell in just one hour at Edgbaston, causing widespread flooding and damage across the city.

The storm was caused by a cold front that clashed with warm and humid air over the Midlands, creating intense thunderstorms and torrential downpours. The rain was so heavy that it overwhelmed the drainage system and turned streets into rivers, trapping cars and buses. Some areas were submerged under 1.5 metres of water.

The flooding affected many homes, businesses, schools and public buildings, such as the Birmingham Repertory Theatre, the Birmingham Museum and Art Gallery, and the Birmingham Central Library. The library suffered extensive damage to its archives and collections, losing thousands of books, manuscripts, maps and photographs. The total cost of the damage was estimated at £12 million. continued in next post...

Sorry, but I'm confused. Why is it necessary to do anything to the shaft? - I thought the requirement was to permanently fit a new phosphor bronze sleeve to it, so why are we talking about hardening it?

Bill: The gear was 3D printed. It's about 50mm in diameter and 12mm thick. It was printed all at once and is impossible to disassemble.

Here's a photo of a herringbone epicyclic gear - all the gears, sun, planets, and annular are all herringbone, and it works fine.

Gerry: Have you tried the Everthing program I suggested? If your file is anywhere, Everything will find it for you. It's small, free, and very fast. What is there to lose?

I installed a rather useful search program that is especially useful for finding files that don't appear where I thought they should be. It's called Everthing. Its free and can be downloaded from HERE

Unlike the File Manager search facility, it's just about instant - no waiting for results at all. Give it a try, you will be surprised at how efficient it is.

Thank-you HP. I'd never heard of INTERNET ARCHIVE before and had spent quite a lot of time fruitlessly searching for the manual. You've made my day.

I have a rather ancient Sharp EL-545 electronic calculator, but lost the manual many years ago.

Sometimes it enters a mode that doesn't show any decimal digits, so that root2 is displayed as 1, rather than 1.414213... etc. When that happens I can't find a way to turn that mode off.

Can anybody help please?

Yup! I was wrong.

I'm confused.

I thought the OP wanted an adaptor to allow a tool with a male MT drive to fit into an INT30 female socket. In other words, an adaptor that fits an INT30 socket that will accept an MT taper tool. The suggestions appear to reference adaptors that work the other way round - to allow an INT30 tool to fit an MT socket.

Am I wrong?

I'm being thick here. On your diagram I don't know what you want to weld to what.

You could try using a DTI with an elephant foot tip.

Since nobody has answered (yet), I haven't tried it and have no intension of doing so. I'll give my views based solely on ZWSoft's website.

It seems to have a very cumbersome user interface that provides very little to justify the prices I saw. The sketching environments for all the parametric CAD systems I've tried provide far superior facilities to the non-parametric sketching of ZWCAD. Once you've tried parametric CAD you'll never want anything else.

As I've mentioned in other posts, ALL CAD systems have a steep leaning curve, so don't waste your time on learning a non-parametric CAD system. YMMV

I'm with S.O.D on this. I use F360 and use a SpaceMouse with my left hand and a Logitech M185 with my right.

Although the SpaceMouse is used only for CAD it is a great benefit with assemblies and complex models.

I tried the AI search engine of Bing, and asked what'#s the difference between modules 5461AG and 5641AG, and got the following response...

According to the web search results, both 5461AG and 5641AG are part numbers for 4-digit 7-segment LED display modules. However, they seem to have different pinouts and wiring schemes. For example, according to the DFRobot1, the 5461AG module is used for evaluation of the KYX-5461AG display, which has the following pinout:

Pin Function
1 Segment E
2 Segment D
3 Decimal point
4 Segment C
5 Segment G
6 Digit 4
7 Segment B
8 Digit 3
9 Digit 2
10 Segment F
11 Segment A
12 Digit 1

According to a forum post on Model Engineer2, the 5641AG module has a different pinout, which is:

Pin Function
1 Segment E
2 Segment D
3 Decimal point
4 Segment C
5 Segment G
6 Digit 4
7 Segment B
8 Digit 3
9 Digit 2
10 Digit 1
11 Segment A
12 Segment F
As you can see, the pins for segment F and digit 1 are swapped between the two modules.
This means that you cannot use them interchangeably without modifying the wiring or the code.
You should use the module that matches your device and application.

F360 has (had?) an app for Android phones. I was able to demonstrate models I'd created on the grown-up version without problems, but I haven't used it for a year or so.

Commas can make sense of sentences that are just gibberish without them.

Make sense of this...

Smith where Jones had had had had had had had had had had had the examiner's approval.

Smith where Jones had had had, had had had had, had had had had the examiner's approval.

Quotation marks makes it even clearer.

Smith where Jones had had 'had', had had 'had had', 'had had' had had the examiner's approval.

For what it's worth, F360, even the free version, will do text on paths as well as in boxes. The paths can be straight, circular, or splines. There's no kerning, but letter spacing can be adjusted. Typeface and size can be adjusted.
