So a bolt is an internal fastener and a nut is an external fastener? Yes - and you need an external threading tool to cut the internal fastener, and an internal threading tool to cut the external one. Wilf |

Leslie - what material did you make your Moulds from ? Did you use a Release Agent ? I used 6mm birch ply. Easy to cut, easy to sand and finish. They only need to do one or two mouldings and the plastic is thick enough to sand away any draw marks. There is no need for release agent for this small run. |

Lets stick to male and female, we understand that even if the woke brigade don't. Jem who still uses a 1970's dictionary!!! I feel sorry for those restoring a Ford Transit mk1 or mk2. Gone are the days of putting a load in your Tranny. OK, I'll drink up and go |

For the uneducated population, this came off the internet when asking "what is a bolt" :-
A bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. Bolts are very closely related to screws. Wikipedia.
It would appear that Wikipedia hasn't progressed with the times!!

You can count me among the "woke" brigade, as in, My son is gay, I have a friend who cross dresses and have always just tried to treat people as individuals and not go out of my way to hurt them. So basically, I don't attempt to make people uncomfortable because of the lives they lead.
The accepted engineering term Male and Female is fine. A complete non-issue, especially as no-one is trying to alienate or upset anyone else, just talk about engineering.
I'd love to see the resulting cap you made using the formers Les.

Yes, but there really are folk out there who object to us engineers usng the male/female descriptors for fasteners etc. Same as there are folk who object to the terms 'master' and 'slave' in control systems.

As with anything, some people will take it to extremes. One of the upsides/downsides to the internet is you massively grow your audience reach: that includes the small percentage of society that will take things to an extreme on either side of the argument! Some people will spoil for a fight for the sake of it, raging at some internalised injustice about the way they think the world thinks about them. Again, there are these people on both sides of the fence. All we can do is be the moderate middle. All most people want is a quiet life, including a vast majority of LGBT people. I hate the thought that anyone within that group wouldn't feel welcome here. That doesn't need to mean overthinking every word we type. |

Today while looking for a present for my Mother I ambled into a local junk shop. Came out with a hurricane lamp that looks nearly new (and a very good quality Feuerhand brand) and some cans marked BR that I suspect contained Detonators for use on the track.
Don't worry, I went to the garden centre in the end and got something for her....

Marked out the rectangle, using masking tape, to apply the right hand side BR crest on Britannia's tender within. Sticking with the later 'ferret and dartboard' type as Grandad built it.
Regards,
Dan

Not British Railways I must add, detonators came in a plastic "tupperware" style container. Yellow with a screw type lid that held 10. |

I confess I've made an assumption its a detonator tin, a bit bigger than a pringles can, rolled from sheet. Whatever it is I'll find a use for it! |

Suppose someone has to say it - you could always store Pringles in it  Incidentally, the term woke goes back a long way, to the Rosa Parkes era at least - it's not new, as most of us imagine. There's a good radio program on BBC sounds Radio 4 tracing the history. Here |

If the tins have 'BR' embossed on the side, and quite a deep lid which clips on, then yes, they probably are detonator containers. I've placed and removed detonators when on traning courses for working trackside, but didn't pay close attention to the containers they came in. I think modern ones are plastic (isn't everything?)

Hello Today I put my wall steam engine together I build years ago. Started to paint but didn’t put it together again. So I thought to look if all the parts still there and what needs to be done to make it run.   |

A most unusual piece. I am liking that a lot.
I can not quite get my head around the timing of the valve. It’s an oscillating engine and would be set to run in one direction? The eccentric drives the expansion link and the position of the cylinder operates the valve?
Great post

I don't think it is an expansion link in the normal sense - it is just a radiused link with a die block for one arm that operates the valve. As the cylinder oscillates, the block moves to and fro in the link.
The link moves up and down on the rectangular bar under the control of an eccentric.
I am liking it a lot too. Looks quite a lump.

Another amusement appears to be the inlet and exhaust arrangements. There's nothing visible attached to the valve chest - the hole in the cylinder pivot, and the four screw holes around it, suggests that's where things are connected.

Apologies that I took so long to upload pics of the mould and former for my tank lid. ibb.co/pbpMDt2Top left is the female mould. Bottom left is the former. Bottom right is the formed lid blank. Top right trimmed lid. |

Just received my Laser Center Edge finder back from SDA. I brought it back around 2007, serial number around the 2200.
A couple of month or so ago I went to use it & it quit! Bugger!
So I contacted SDA to see if it may be possible to fix it, reply, no problem send it over. So after paying an exorbitant amount for post……it was duly sent. Eventually it got there & I got an email saying sorry tried everything & it’s not repairable! Bugger again! Ah well I’ll just have to buy another one. Any way life got busy & I hadn’t ordered when out of the blue I get an email to say it’s sorted! As it wasn’t repairable Skip had put in new bits & the cost was very reasonable, the postage how ever wasn’t, but it got here faster than it went, guess it’s all down hill from the States!
Anyway the usual disclaimer just a very happy customer & wishing more companies would provide service like this, especially as they are only a 2 person company!
Cheers Kerrin
