McAfee has just informed me RMWeb is infected! And has illegal content. This is odd, as I do not have McAfee installed...

This is a scam, but likely one being served through the ads. The idea is to scare people into clicking the "Scan" button, which will then download malware.

The image was served from this web address (probably, but not necessarily, safe to click on):

I have had mine just over a year, using it say twice a week on average. I have not cleaned. I empty the vat, and filter the resin any time I think a print failed such that there are bits left in there.

I have never used PTFE spray; never seen the need. Doubt it dissolves in resin - PTFE is notoriously difficult to dissolve in anything - but not sure it actually does any good.

We are having a night in Mallaig, and spending a day to get to Inverness (1713 from Kyle), so plenty of time. Taxi is the backup plan, but kind of feels like a cheat when we do these things...

Good morning all,

 

Thanks to your advice on seeing a bit of the West Highlands with a few days to myself, I've finally booked my trip. I've kept it quite short and I'm sure there were better choices to make, but it's all booked now so I think it's a bit late to make any changes!

 

The main thrust of the trip is a journey across the West Highland line from Glasgow to Mallaig and then back via Kyle to Inverness, but I'm also going to have a few hours in the major cities and I was wondering if there were any really iconic or interesting railway sights to see while I'm there? I'm pretty happy looking up non-railway things (though any off the beaten track recommendations would be gladly taken), and I don't have a car with me which will limit me a little - but I would be very grateful to hear any ideas:

I have just bought the tickets this morning to do the same trip. I will be doing it in August, with the family in tow, with a few nights here and there. A re-run of the trip I did just over 40 years ago, with my parents. How are you doing Mallaig to Kyle? Forty years ago there was a direct ferry, but it does not seem to run now. We are getting the ferry to Skye, then two buses.

Just come across a photo of a class 24, D5069, on the ECML taking rubbish from London to a landfill in Hertfordshire, in 1961. I am interested in modelling the wagons, and wondered if anyone could give some details? They are open bogie wagons, covered with tarpaulin and look like they may be wood-sided.

The photo is in "The Heyday of the early British Rail Diesels", page 25. It is black and white, and any ideas about colour would be great too!

How long did the service run? I know that later they used "bin liners" to take the rubbish out beyond Aylesbury; I have a feel that was mid-eighties maybe?

Sorry, no help at all... but can you tell me what project murcury wagons are?

Possibly a question no one knows the answer to, but how far apart were the two sections of the train as they approached Carlisle? I am wondering how long he had to change the points so one section went one way, and the other a different way.

Some interesting features that I would love to have, but not sure I can justify...

Looks like it has a PFA film rather than ACF. Does that indicate PFA is superior?

I wonder if 19 mm is a wargaming scale? 

I am looking to make some of these. They are some great images here:

https://paulbartlett.zenfolio.com/procorcovhop

But none show the top. Would anyone have any idea what would be up there?

I am guessing a platform to walk on, accessed via the ladder, which is the bit the sticks up from the curve. Looks like three sets of three somethings on top in some images... Would there be three compartments internally? And I guess a hinged metal cover for the the openings. Would each compartment have three square openings or one longer one?

Has this one been on here yet? Avoided the bus-on-a-bridge cliche by posing a lorry on there.

Don't often see mixed gauge?

 

 

The single slip on the left shows how complicated it gets with dual gauge. The standard gauge crosses from right to left on the curve.

If stuff fails to print on one section of the build plate, but okay on another, it is probably a levelling issue.

I doubt it is mixing. I leave mine to stand in the vat for days and before printing, and it is fine. When filling from the bottle, I turn the bottle upside down a few times; I avoid vigorous shaking because of the bubbles. I use Elegoo 2.0 resin, but I guess that is pretty close to what you are using.

Stl files are undimensioned. So your problem may have to do with what your CAD software is outputting. 

I do not think that is quite right. They have dimensions, but not units. That means the software will try to guess if you mean cm, mm or even inches. It does not mean it will be a random scale.

I use Blender and work in meters in there. The STL file has no units, but ChiTuBox usually just guesses mm because that is what fits the print area. For a small part it guesses cm and I have to scale it to 10%, but I once had it guess inches and had to scale it down to 3.94% (=1/25.4x100).

I am waiting for better weather to use my new resin printer.

My printer is in the garage, which is not attached to the house, and pretty cold in winter. I have a vat warmer, as used by home brewers, but even with that it is not worth printing if the outside temperature is below about 8°C. I managed to do quite a bit a week or so ago when it was warmer, but back on hold for now.

I use Blender. The full version is free.

I have written an introduction to using it here:

http://www.prestonanddistrictmrs.org.uk/articles/using-blender-for-3d-printing/

And some examples of wagons I have printed on my blog:

Not come across these before.  Can anyone tell what these, and the earlier 'Tubes' carried, please?  Pallets of sacks?  Sacks loaded loose?  Thanks.

 

My understanding is they carried pallets 45-gallon drums in the end compartment, and larger drums on cradles in the centre. I guess it was for lower volume chemicals (i.e., less than a tank wagon) between sites.

Thanks a lot. I looked on the site, and I just could not see it!

Further question: Could any one say what colour they are? I see two images of them in ICI livery, taken at Stoke Wagon repairs in 1981, and there is an ICI logo on the right end. I am red-green colour blind, but my feeling is there are very faded red? Pinkish grey maybe? Bachman do an ICI open for 009, and I wonder if these would have been the same red originally?

I am part way through making a model of an open wagon that ICI used ca. 1980. I am sure I had photos of it at one time, but cannot find any now.

They were later used by Redland, and I can find an image from then.

In the ICI day they had partitions dividing the wagon into three parts, and this is what I am modelling. And I must have seen an image to model it! 

Anyone able to help?

Happened to me a second time. This is the page it takes me too. 

I left an RMWeb page open. When I cam back a few hours later, there was a message supposedly from McAfee saying my anti-virus had expired and I had to take action.

This was undoubtedly a scam, and taking the action they wanted would have resulted in an infected computer.

The browser had redirected me to a new web pae that used the domain eu.securitypatch.life . I would guess this resulted from one of the adverts on the page. Users should beware, admins will hopefully investigate and stop said adverts.

At the risk of flogging a dead horse, my last idea + your last idea =

 

 

 

How about inverting this so the fiddle yard is on the inside, and at a lower level? You would have a long run, everything should be accessible, and it will be a lot easier than a helix.

For 3d, I would recommend Blender, though it is not strictly CAD.

For 2d, I agree with Buhar that InkScape is a great choice, being both free and easy to use.

That is indeed very similar, and almost certainly better (less laborious!) than my technique.

 

The downside is every lump of coal is rectangles and right angles - no variety in the shape. How that will look when printed, I do not know. There is likely a way to resolve that, but I have not used geomtry nodes much at all.

Here is how it was set up.

ETA: Updated image. This uses a dodecahedron as the basic lump of coal (you need to activate an add-on "Add Mesh: Extra Object") . Also has a "Realize Instances" node just before the end - if not there, the coal does not show up in the STL file!

You can do similar in Blender using geometry nodes.
