Could also be a way of entering a secret society if you say Ow, eee, yow the correct way.... or maybe it summons the derailment elves????

The reason I, and many others, don't use Bookface is because of their information mining of personal data. I hate this and feel my personal information is none of their business.

Hattons have a major fault with their ordering system which I have encountered. It cannot cope with orders for low stock items where two (or more) people order the same item at the same time. One will be lucky and get the item in their trunk. The other will get a message that looks like the order has gone through. When you check the item isn't in your trunk and the order has vanished. Just something to be aware of.

I think if a Metro tank were to be made it would have to be almost generic. There are so many variations it would be damn near impossible to settle on one unless... the last batch from 1899. Some from that batch that hobbled in to 1949. Others from the 1894 and 1892 batches also survived WW2. https://brdatabase.info/locoqry.php?action=class&id=124052&type=S&page=fleet There are a few surprises in the above list like some of the 1869 batch lasting until 1934. Still, some reading for you guys!

If you are going to use the mill I wouldn't use wood. The frames need to be clamped down very firmly especially if they're thin. If the cutter decides to snag you will bend them and cut material out you didn't mean to. Bolting to either a block of aluminium or steel with lots of clamping point is best. Tooling needed; Quality milling chuck such as a Clarkson Autolock with it's collets (small version. Beware! they were made in three sizes!). Collets are in two sets of four (metric and imperial). Metric have a groove in the outside of the flange to distinguish them from imperial. You need to know what the spindle fitting is on your mill. I'm guessing MT2 but check first. Many small mills don't use a drawbar to retain the chuck and instead use a flange. It may be the case that you have to buy the original Emco chuck however. Cutter; slot drill is probably the best option especially if it is a four or six flute. Don't get a two, this is more likely to bite and cause damage. Make sure it is HSS and is a good brand. Don't buy a cheap unbranded one! To machine the item use lots of *very* thin cuts. Maybe 0.1~0.2mm at a time and go very, very slowly winding that handle. One wrong move and you might be buying a new set of frames!

Some of us refuse to use BookFace. Bit unfair that they exclude people by using that.

Entered!

Just had a note through that some (LNWR in my case) have arrived ahead of schedule. Probably going to be a few days until they arrive given how many orders they have to deal with.

I think it would be a nightmare trying to keep 224 3 metre lengths clean. According to one supplier this could weigh 76 kilos. Peco code 100 is about 26 kilos. The more weight I add to the decks the stronger the scissor assemblies have to be. My maths isn't very good so I am a little reliant on what I call 'Holbrook Mode'*. * Holbrook was a lathe manufacturer who made their machines insanely over-engineered. A lathe with the capacity of a Myford ML7 (two strong people can pick one of these up) made by Holbrook would be over a ton and built like a nuclear outhouse.

The deck frames are aluminium ladders with the ply bolted to it, this is what the 700 drilled and tapped holes are for. It gives me a multitude of attachment points. Because it's thin the ply has no option but to obey and be flat! MDF... weight and dust plus trying to use conductive tape in place of rails could be extremely problematic. One small wrinkle and you get a derailment in a difficult to get to place plus MDF doesn't, in my experience, ever have a nice edge post-cutting. Cutting the grooves is doable, I just need a router. I have suitable guide rails for my saw and the right adaptor for a router. Getting the grooves accurate means it would have to be done on the mill though. I wouldn't want to do that, it would make an awful mess.

Fair point but why would anyone pay £300 for a kit which retailed for £50-60 for which the tooling still exists? This is why I said 'silly' because at any point production could've restarted if C*opercraft weren't involved. The tooling is back with Slaters now. Some of the Midland coaches are back in production but not the Toplights or Clerestories as yet...give it time. Moral is don't overpay for something where a new batch could be made even if you have to wait a while. Have I ever seen an item and the must-win-at-all-costs mentality descends? Yes. What was the item? Motorcycle dealer's badge. What did I bid for the item? £101. What did I win it for? £6.50. Why did I want it so bad? Dad owns a motorcycle that was sold secondhand through that dealer in 1957. Both original badges on the bike had been polished to oblivion. Chances of finding another? Virtually zero.

Another vote for a heat gun here. If you have loads to do it's safer and you don't get the risk of fumes released from the plastic. Have a look and see if they still make them for aero modellers. There used to be an Irvine branded one amongst others.

I'm sitting here sniggering at the silly people who were paying £300 for the Slaters kits on Ebay some time ago.

Nice idea but 2mm aluminium isn't that easy to get. Most of the suppliers I have previously used don't go below an 1/8" (3.175mm) It would cost about £1700 for the 224 lengths needed. Regarding the decks; they are to be 3.6mm ply to save as much weight as possible.

Seeing as they're making a number of 00 4-4-0's how about a LMS 2P? This means, as we wait for their next announcement, we can say '2P or not 2P?' I'll see myself out....

Have a look at linear actuators with a pair of linear rails of sufficient length. The latter act as guide rails which, correctly attached, will prevent twisting. Regarding the actuators; you'll have to find one with enough travel and load capacity. Secondary drive option would be a larger ballscrew but these can be a minefield. Most you see are cheap for a reason. These can be driven with a stepper motor. Ballscrews often come as a kit with bearing blocks and motor coupling. Third drive option is a trapezoidal screw and nut. This is the strongest of the three but will have to be driven from a gearbox and a decent motor. This option does require a lathe to machine the ends of the screw and a mill to make the bearing blocks. With all options there must be a safety interlock. You do not want a failure to send the whole lot crashing down. A door bolt each end operated by a servo would do this job. I have also seen these lifted with cables. There was a video of one somewhere but I can't find it. It was in G scale I think.

I can see why. The majority of my N gauge stuff was made in Poole. I was having to clean the wheels and pickups often. Given how fiddly modern models are I wouldn't want to take them apart for servicing. I would be interested to see a longevity comparison between the two systems of current collection on modern models.

Looks like this thread has taken the diversion to Bicker Central from Maddening Junction....

The majority of manufacturers have gone over to wiper pickups because this doesn't suffer the problem that split chassis often do. Using axles with an insulation bush in the middle and having a chassis made in two halves also with insulating bushings is a very cheap way of making a model. This sounds good but the axles are now trying to do two things. What has always happened is that the conductive coating on the chassis halves wears out and then you get running problems. Some models got alot of use and it wore through the coating resulting in reliability problems in the long run. It was used by Mainline whose tooling was inherited by Bachmann. They have been replacing split chassis models with wiper pickup versions. Now we come to the unpleasant subject of DJ Models who also went down the split chassis route. It was pot luck if you got one that ran alright or not. Their reliability was not good... some failed after less than two years if you were lucky enough to find one that ran for that long. Many of these models are now being sold under the EFE Rail brand. I have no idea if they fixed some of the poor design choices made by the previous manufacturer. Have Rapido solved the problems with split chassis? I don't know.

Raise and lower? I have to get my head around copying something like this; This is where I have mostly come unstuck. It has to be welded together but, though I have had a bash at aluminium MIG welding, this needs high strength welding. Mine doesn't look bad but with the forces this might endure could cause a failure if they aren't 100%. The greater issue is that if they aren't 100% accurate binding and jamming could occur. Problem two; my lathe has too smaller spindle bore to machine some of the parts needed. 31.75mm bore when I need 40mm.

No problem, it was a good suggestion. Quite a few have rightly pointed hunting at shows.... technical problem; I don't have a driving licence. My Dad used to take me to shows but he cannot drive anymore. It makes things much more difficult to get around when he can't be left on his own in case he falls.
