There doesn't appear anything wrong with the photo of 6861. There is the main piston rod below, and - slanted to the inside - is the valve rod. OzzyO's assembly is the same as that.

 

Hello Horsetan,

 

it's the orientation of the stuffing box on the piston rod (on the model) that is angled wrong, it should angle this way / not the way it does \.

the method you describe is clear, and will be the most expedient

 

I suspect that the right answer is to ask for a pair of handed castings...

 

annoying, I sympathise

Hello Simon,

 

slightly annoyingly these casting were handed with the hole for the pressure relief valve cast in place.

great post and I love the detailed descriptions of what you are doing.

 

One thing that puzzled me though was the picture showing the cylinders from behind ( the first picture).

 

I was expecting that the orientation of the cylinder assemblies would be symmetrical about the middle but the main cylinder block on the left hand side when looking from behind is not a mirror image of the one on the right hand side.

 

I looked up a photo of a grange prototype(attached  -zoom in to the cylinder) and it does look like there is something wrong at the back of the left hand cylinder where the piston rod enters - this should be orientated  bottom left to top right??? ie comparing left and right cylinder blocks /.....\  and not \.....\

 

Does that make sense or did the prototype vary in the orientation?

Is this due to an error during the kit design process or intentional for copyright reasons?

Hello all,

 

this will be a long one so as I do always say get yourself a drink, one of the first jobs was cutting the packing bits of brass back. As you can see I got one of the cuts a bits out. This will be sorted out later.

post-8920-0-10854900-1434658674_thumb.jpg

 

For the oil pots on the slide-bars I had a look in one of my bits box and found these, the one on the right is how these are cast. Sorry about the quality of the photo, the marks are 0.5mm.

post-8920-0-20827700-1434658729_thumb.jpg

 

In place on the top slide-bars.

post-8920-0-98892800-1434658761_thumb.jpg

 

and in very close up.

post-8920-0-01217000-1434658790_thumb.jpg

 

Starting work on the brackets for the cylinder drain cocks, these still have a bit of work to do on them.

post-8920-0-34259800-1434658793_thumb.jpg

 

Starting work on the drain cocks operating linkage, as this kit is from approx. 1991 these were not included in the etch, so if you want them you have to make them and I did want them.

post-8920-0-54514000-1434658798_thumb.jpg

 

The two of them cut out and a bit of tidying up work done.

post-8920-0-33835800-1434658803_thumb.jpg

 

The curve formed for fitting them to the cylinder body.

post-8920-0-60416600-1434658811_thumb.jpg

 

And fitted in place, the R/H end needs a bit of work doing to it to get it to look a bit better.

post-8920-0-98655300-1434658816_thumb.jpg

 

The operating links for the drain taps bent to shape, yes I do tend to make more than I will need.

post-8920-0-39071900-1434658823_thumb.jpg

 

And them in place on one side, the one for the valve drain tap needs a bit of work on it (the joy of digital cameras).

post-8920-0-96274600-1434658829_thumb.jpg

 

Then it was back to the main loco frames and apply the overlays to them, these have had the holes for the brake pivots and the pick-up holes drilled out to size.

 post-8920-0-13774300-1434658840_thumb.jpg

 

The castings for the brake pivots cleaned up and tinned, for the tinning on these I've used 180Deg solder.

post-8920-0-73047700-1434658849_thumb.jpg

 

Then it was onto the wheels. The way I do the wheels is as follows, clean up the back face of the wheels on a diamond sharpening block (or some wet'n'dry on a flat length of wood) this will clean up any bits that stick out. Then clean out the hole for the crank-pin (as I use 10BA for the pins that is 1.4mm) then I counter sink the back of the wheel 3mm. After that it's a wash in cellulose thinners and a quick dry, then clean the brass centre with a small brass brush on the outside only. After that all the wheels are washed in meths and dried using kitchen roil.

post-8920-0-61838800-1434658858_thumb.jpg

 

Then it's applying Birchwood Casey gun black to the wheels in the following order. The brass centre, then the outer rim (I don't do the wheel tread) let it dry for a short time then turn the wheels over and do the inside of the wheel rim, and this is what you should end up with.

post-8920-0-14911000-1434658877_thumb.jpg

 

After this these will be painted using a black etch primer on the outside face only, after the balance weights have been fitted.

 

I was in a shop called Sally's it sells nail varnish and stuff for the hair dressing trade when I spotted this set of tweezers (the bottom set) these did cost about £8.50 but they do look a good set. The ones at the top are from Squire's and cost about £6.00 but go rusty when used with flux. How the new ones will react I don't know?

You blessed us with a picture of your nail recently. Now you admit to going into Sally's: for nail varnish perhaps

Have you seen how long and wavy his curly locks are ?

 

He probably went there for a " perm lotion and false eyelashes "

The nail varnish in Sally's is too expensive starting at about £4, so I get mine from the £ shop.

 

False eyelashes and a purple rinse that would go down a storm at Telford, dear.

PS. I'm going to get you three at play-time.

Hello all,

 

well this post has been a bit of a pain as I've had to up-load each photo (using Adobe Flash player 18.0????) As I've always used the same flash player to up-load any photos what is going on?

 

The driving wheels after having a coat of etch primer.

post-8920-0-82710900-1435762633_thumb.jpg

 

Checking the hight of the frames above the driving wheel axles on the front and rear ones.

post-8920-0-40757600-1435762668_thumb.jpg

 

Then it was setting the middle set to allow them to move approx. 25 thou. above the centre line.

post-8920-0-66861700-1435762696_thumb.jpg

 

The vac cylinder before and after cleaning up.

post-8920-0-78372100-1435762757_thumb.jpg

 

Not that you can see that much of it! when it's in the frames.

post-8920-0-95002400-1435762805_thumb.jpg

 

After cleaning up the Slater's axles in cellulose thinners and a clean in methylated spirits. The bl00dy things started to take on a rusty finish in a few minutes but when you apply the gun blue it works and stops the light rust. Sorry no photo of this.

 

Then it was onto the brake gear this photos shows most of the bits for this, the only parts not shown are the bits that look like small spit pins,

post-8920-0-28506700-1435762873_thumb.jpg

 

Starting to fit the brakes and making sure that they should not touch the wheels. This also shows why I keep the paint on the wheels it's a way of keeping the hot flux off the wheel rims.

post-8920-0-94376100-1435762906_thumb.jpg

 

Checking the length of the safety chain when the cross beams are in place.

post-8920-0-67167000-1435762938_thumb.jpg

 

Then  you can check the length of them together using a length of 0.4mm brass wire.

post-8920-0-47305600-1435762993_thumb.jpg

 

In place on one of the brake cross beams.

post-8920-0-54616900-1435763020_thumb.jpg

 

Well that's all for now, If anyone can help about my up-loading of photos please let me know.

The cylinder wrappers in place, I've still to fit the following. A length of 2mm square brass to the inside top edge of the wrappers, the drain cock frames and the drain cocks. The wrapper only have two 

As seems to be normal with me I always seem to cut myself when building a loco kit. This is what I did yesterday while forming the wrappers to shape, nice!!!!!!!

attachicon.gif001.jpg

 

One job that I've still to do is check my photos for the position of any oil pots on the top slide-bars.

 

OzzyO.

Seems to be an occupational hazard. I drilled this finger just below the quick. Amazed to see how close I was to drilling through the hidden nail when it grew. :sclerosis:

Where do you get the chain for the safety chains? Looks good.

 

If I'm uploading files I just use browse and select the image. Flash player doesn't seem to come into use: it's for video. Are you trying to upload a video?

Have you altered your camera settings since your trip to the NRM? Are you trying to upload pics with to much resolution

Didn't take the camera to the N.R.M. just my mobile phone so the settings are the same as always.

I get the chain from Squire's ref No.5627/03. It's about £5 for a meter and a meter does a good number of locos.

 

When you click on reply with attachments, you see Attach files at the bottom of the page, then below it Browse, then below that Attach this file, then below that"Try our advanced uploader (requires flash 9), I've been using this for a while as it allows you to upload up to eight photos at a time (with some of my posts that's a godsend). But since I've updated to Adobe flash player 18.00??? I've been having problems.

Hello all,

 

first post on my build thread for a long time. But it's not going to be the Grange at the moment, it's going to be a bogie bolster 'C' from M&M models Welcome wagons range.

http://www.modelrailwaywagons.co.uk/Index.htm

 

This is the first kit that I've built from this range.

 

To start with the castings, in this bag, the tie down rings (these look like they could be used in the loose or with tie down chains in position), the side stanchion pockets these come in two types empty and with stanchions in place. There may be more in the bag.

post-8920-0-61689700-1485086956_thumb.jpg

 

The deck bolsters,

post-8920-0-73772600-1485086960_thumb.jpg

 

Buffers (these are getting replaced with sprung ones), couplings (I may replace these latter on) and some other bits and pieces.

post-8920-0-90907000-1485086963_thumb.jpg

 

The replacement buffers.

post-8920-0-35204100-1485086967_thumb.jpg

 

Staying with W/M onto the bogies.

These are quite simple as they are only in three parts, but not with out some small problems. The main one being that the holes for the bearings are cast at about 1/8" (approx. 3.1mm) and the bearings that I'm using are 2.5mm, so to take up most of the slack I used 3mm tube.

post-8920-0-27827800-1485087025_thumb.jpg

 

The main parts for the bogies laid out, the wheels are from Pear tree engineering ( http://modelrailwayparts.com/index.html ) these are steel wheels with a small 'plastic' insulation bush near the axle. The axle bushes are also now fitted.

post-8920-0-28744600-1485087032_thumb.jpg

 

The first bits soldered together, this is why I'm starting on a wagon kit first as I want to check how my soldering is before I start on the Grange kit.

post-8920-0-50703800-1485087038_thumb.jpg

 

The completed bogies, the only down side that I can see is that there is no brake gear, it's not a big problem as you can hardly see anything of them on the real thing.

 

post-8920-0-48936100-1485087043_thumb.jpg

 

The brass etches, the foot rule gives you an idea of the size of the wagon.

 

post-8920-0-80885800-1485087092_thumb.jpg

 

post-8920-0-94716400-1485087097_thumb.jpg

 

In the instructions it recommends opening out the half etched folding lines, this is some thing that I strongly recommend that you do. To do this I start with a three square riffler (is that spelling correct?) file then finish off with a square file. You can see the before top and after below.

 

post-8920-0-84266300-1485087110_thumb.jpg

 

The main body made up, this was just a matter of folding the brass up. The way that I did it was the top flange on the sides in my bending bars then the main sides using a flat bar and a flat base, then the ends in the same processes.   

 

post-8920-0-99919600-1485087112_thumb.jpg

 

Then the first bit of real soldering, the first buffer beam you can also see some marking out lines on the base of the body.

 

post-8920-0-69139800-1485087117_thumb.jpg

 

More to follow so watch this space,

 

OzzyO.
