Aren't Slaters and Springside kits complete?

 

 

Jason

If they are, my apologies.

 

My interests being banger blue diesels and BR(E) steam, neither have been investigated.

I`ve remained open minded about this enterprise.

 

Hatchette specialise in kits for the absolute novice  and so I`m not surprised they hav`nt included the `conjugated valve gear` which  wont be seen on a valenced version.

Lets be honest, a novice would be hard pressed to get it working in any case.

 

There are plenty of O gauge  models around with non moving inside valve gear and I for one will be content to finish with skirts removed ( because I like the look of A4`s this way) but will obtain as many missing castings from LG  as he produces.  ( I had a bonus sell up on ebay over Christmas)

 

I`m sure in the future I will get a lot of my investment back when I sell on and by then it will have all been forgotten.

 

 A decent coat of paint will hide a multitude of sins.........

 

However, it has put me off completely  in signing up for any more of their locomotive projects.

 

 

Mallard is my first Partworks which to be honest I planned to build in the stages as published as a bit of light modelling relief from my main build interest, thinking that it wouldn't take much time away from that. It was also a way of doing so in part payments which wouldn't affect other more important budgets, although I have no issue with buying expensive kits, I still have an untouched Finney A1 and corridor tender to make a start on one day. Alas, I found that I was having to spend more time on the build than originally planned, removing the lacquer from brass parts both being a pain and taking more time than originally envisioned. Therefore I stopped work on the model, carefully storing the mags away for when I could give my full attention to them to give the model the justice it deserved, continuing with the subscriptions to collect a full set..

Despite it's few shortcomings having a professional modellers background I can appreciate a well-detailed model when I see it. 

Will I buy partworks again?  probably, especially if they do a series on Gresley teaks which I feel would be a winner for everyone, I have passed on this idea to the magazine and hope that they act on it one day...we shall see...:)

Still trying to look into the valve gear bits that are missing, but am having trouble contacting anyone.

Everyone must be closed for the holiday, or away.

 

I'll keep trying.

OK, I have now made contact with a professional modelmaker who is willing to assist.

 

It's obviously going to cost me as an initial outlay, so I need any interested parties to contact me, either on here, or on the Facebook Hachette Mallard site, so I can get some idea as to whether this is going to be financially do-able.

 

I THINK the valve guides are available from Laurie at £10 set, but I need him to confirm that this is so, and that we don't need TWO sets.

 

This leaves us needing castings for front and rear valve rods, two sets, left and right,

two radius rods, left and right, to be produced as double thickness etchings to give the correct shape, and,

the conjugated valve gear, again produced as etching, although some may wish to leave this off as it's not that visible,

 

Seen here on 60008:

As stated, let me know, preferably with contact details, so I can update you as this progresses.

Thanks.

Hi,

 

I'm a bit late replying to this, but we have only in the last day or so sorted out the layout of the valve gear on our W1 test etch, or more particularly that the valve gear will be on its own etch, and can therefore be made available as a spare part from our kit.

 

For those that don't know, Finney7 is working on a 7mm scale rebuilt W1. The valve gear is all but identical to that of the A3 and A4. It will be in 0.7mm nickel silver, and with the addition of our valve guides, will provide you with all you need to build a faithful rendition of the full valve gear, including the lubricator drive. Obviously, it may need some fettling to suit the Hachette model, but at least you will have an accurate starting point.

 

The valve gear etch is shown below:

We haven't got prices yet, but I would expect the valve gear etch to be available at around £50.

An etch of that calibre would be a useful thing to have in 4mm scale too....

Thanks, Richard, to be kept in mind.

 

What about valve rods? They are normally nickel silver castings...or at least, they are on my Piercy A4.

Nickel silver rod - the ends are on the etch, bottom right and adjacent the combination lever. Or you can try getting spares from DJH.

You may be able to get the cylinder valves, (Valve guides) from Finney 7, but not yet. AFAIK, they aren't yet available and the LNER models seem to have taken a back seat...surprise surprise, LOL.

 

Meanwhile, Ragstone (Andy) THINKS he might be able to supply at £10 per pair,  and he thinks he may be able to do the valve rods too. I can supply him with masters so we'll see.  Plus I'm awaiting a response from Laurie, who seems to be out of contact. I've tried phoning too but got an answering machine. I think it's the time of year. Not that we are in a hurry, or at least, i'm not...my Mallard contract will be up and complete in July, I reckon.

 

The above  Finney 7 valve gear is very nice, but would be an expensive option, given the amount on the sheet we don't need. I have someone who might be able to draw out just the bits we DO need, and then we can get a sheet etched up for ourselves and just have the radius rods and conjugated gear if required). A sheet would hold enough for about two dozen sets which is easily enough if the demand I'm seeing so far is right.

 

I'll know more in a couple of days. the bloke i know who can do CAD has to get his head round what he knows and convert it into what the etchers want. He is used to SolidWorks, so we need to know if this will work for etching.I will also try and speak to the etchers on Monday.

Off to the NRM tomorrow to look at drawings for the radius rod.

 

£26.50 for ONE COPY!!!!

 

Best take my compact camera..........LOL

Hi Jeff

 

You may find this of help, It's drawn for 5" gauge (that's 11.3 to 1)...you could easily scale from this, I think you'll find it's very accurate and faithfully follows the prototype...I can supply you with any other motion part in this gauge if off use??

Hi All 

For the benefit of mere mortals like myself who will more or less make do with what hachette provide us (particularly for the skirted version which was always -after all what the partworks was offered as) It looks  that anybody who wants older issues for one reason or another should purchase at the lower price before the end of January as after that the issue price will revert back to the original as is now the case with issue 120 to completion.I may be wrong but i wouldn't want to take  the chance -so dally not!!

Now that is excellent, thanks.

I assume the dimensions are for 5" gauge, so if I multiply each by 11.3, I'm at full size? Then divide by 43.5 and hey presto.

 

Also, either I'm not reading it right, or the length of the fluting isn't shown?

 

I don't suppose you have drawings for the front and rear valve rods, and the conjugated gear?

Or the valve guides???

 

Many thanks again.

The rods that go from the radius rod at the rear, into the valves, and from the valves at the front, onto the conjugated gear.

They would be a rod with a forked end? And work the valves.

 

Meanwhile, many, many thanks for the above. Along with the parts I have, and the photos I took today at the NRM, we should be all set.

Apart from those valve rods, plus the rear valve guides and the front valve guides, more recent type, photo attached.

Looks very similar to the rear ones to me......?

ahh.. ok I understand what you mean now.. no rods as such...in your picture you can see the connecting link which goes from the 2:1 gear lever to the valve crosshead.. her's the drawing for the link.

 

connecting%20link_zpsgr7jw6aj.png

 

Now the other parts are made up with crossslides, front and back and a valve spindle in between as per this drawing....

 

valve%20crossheads_zpsvbouosra.png

 

 

 

if you look at the general drawing I gave earlier of the valve gear you should be able to work out how these parts connect, the cross slides run in the front/rear steam chest covers, I'm afraid that i don't have drawings for the later type of cover as shown in your picture.

Has anyone on here gone as far as receiving, or building the valve gear?

 

I'm after pics of the expansion links, please? How Hachette have done it will be important for the design of our radius rod.

 

Thanks.

The expansion link castings were in 117, the return crank rods or eccentric rods came in 118 and 119 and were attached to the bottom of the expansion links.

Then all the bits are put away to paint the wheels.
