Beautiful work Ozzy..

Not sure I could warrant the time on tender brake gear, so hats off..!!

I'd rather spend the time on brake gear that can "just" be seen than something that can only be seen when it's only on shed.

After a fun half day out shopping I did manage to get a few hours in the workshop, the first job was to get all of the step treads in place. This is always a job that can take some time to get them all in the right place and lined up,
002 024.jpg
A bit of cleaning up required but this will be taken care of in the grit-blaster.
002 025.jpg

The next job was to clean out the bores of the buffer bodies, to do this I solder them to a length of 1/4" brass strip and drill them out,
002 026.jpg
Then it was soldering them in place on the buffer beam along with all the rest of the buffer beam details, it looks like I may have some work to do around some of the nuts on the buffer body bases.
002 027.jpg
The next fun packed part of the day was cleaning up the 24 parts for the axle box's and springs. This is a job that just takes a bit of time so some good music and chill out while doing it 24 times. Then it's deciding do I grit-blast the frames before fitting them or only after?

Hello all,

this could be a long post so get a brew or something stronger.
The last parts fitted to the outer frames, the axleboxs and springs. There are a few bits to be fitted after painting.
002 030.jpg
Getting the next parts for the body ready,
003 063.jpg
The fire iron support in place, this looks so much better than the Y shaped one that is supplied in some kits.
003 064.jpg
The lifting brackets fitted to the rear tank top, you have to plot the position for these.
003 065.jpg 003 066.jpg
Starting work on the coal hopper bottom. This is supplied over wide to take in to account for any tender with the tall footplate. From here on I'm only working on one tender until I can determine the hight of the Grange footplate.
003 067.jpg
The hopper bottom cut and filed to size on the left.
003 068.jpg
and in place, it is worth getting a nice fit at the front end.
003 069.jpg
The hopper rear soldered up and cleaned up.
003 070.jpg
But you are left with this, I'm not sure if this is due to me fitting the hopper rear to the rear of the sides, or if I should fit the hopper rear to the inside of the sides.
003 071.jpg
and filed in, it's not the best fit that I've done but it will be covered with coal,
003 071a.jpg
Preparing the front of the tender by removing some rivets to help the fit of the small footplate steps.
003 072.jpg
The footplate steps in the flat and folded up,
003 073.jpg
after soldering up you may have to clean up the joint faces, the one on the left has had all of the faces cleaned up.
003 074.jpg
In place on the tender front. Along with the tread plates and water taps. Does anyone know for certain the position for these when in the open position?

Hello all,

getting close to finishing one of the tenders, the only bits to fit are castings. The first bits are the brake and scoop stations and the small brackets, one thing that I do to these is to extend them at the bottom using some 2.5mm tube. One thing that is a bit of a pain is having a tag in the small radius in the brackets.
003 076.jpg
and in place,
003 077.jpg
003 078.jpg 003 079.jpg
The tank vents in place.
003 080.jpg
I think that this photo "may" show why I like my grit-blaster, the one on the left will have a few more casting added to it and the work will stop on it as I want to check the footplate hight on it with the loco. The one on the right will be fully finished as this one is going behind a Castle and I do know the footplate hight for this one.
003 081.jpg
The last of the parts to be fitted to the tenders have been cleaned up, on one of them I'm using the Malcolm Mitchell etched tool boxes.
003 082.jpg
After this it's just a clean up in the grit-blaster and a good wash in the ultrasonic cleaner, then it's going to be a coat of etch primer.

PS. next week I should be starting on the engine, for one of the tenders.

Hello all,

well I've made a start on 6869, but first I'll let you see 'my' etches! First the two sheets of N/S a lot of these won't be used for two reasons, some of them are for the three 4mm gauges and some of them will be replaced with by the S.D.K.
001 001.jpg
The first two sheets of the brass etches, most of these are for the upper works.
001 002.jpg
The third sheet of brass etches, boiler cab and a few other bits.
001 003.jpg
Getting ready to tack solder the two frames together, part one.
001 005.jpg
and part two.
001 006.jpg
The frames after tack soldering together.
001 007.jpg
After a bit of cleaning up and drilling a few holes and marking out a few more. OK who has nicked my springs?
001 008.jpg
In the above photo you can see some scribed lines that are on a radius from the axles centres these are to check for the plunger pick-ups (4mm Gibson ones) so only a 2.5mm hole. You can also make out a vertical line to the right of the brake hander pivots this is for the safety chain hangers. To do the above I cleaned up one set of wheels, before on the left.
001 009.jpg

PS. what else can I cut from the frames????

Hello all,

back to the tenders for this post, getting the position of the toolboxes marked out.
003 083.jpg
You can see the outlines of the toolboxes in this photo, I'm going to remove all of the rivet and bracket detail within these lines to make sure that the toolboxes sit down on the tank tops.

This is the grit-blaster that I use,
DSCF0325.JPG
To give an idea of size the rule in the M/C is 12"
DSCF0329.JPG
For grit I use aluminium oxide, I think it's about 120 grit. I got a large bag off Ebay.

I think it was about £150 when I bought it, but then you have to have a compressor that will put out about ten cubic foot of air per minute as well so add on about another £150 (or about £80 if you can get one from Aldi).

Hello all,



after looking through my Hall photo I came across this one showing the second boiler mount in about the same position as the cover plate on 6869, so boiler No. C6204 could be a Hall boiler?

Copy of hall4929 1963.jpg

Most of the last days has been spent working on the horn-guides and blocks, you now get cast horn-blocks with them but I'm going to use the turned ones on the right.
001 010.jpg

The blocks blackened and nuts for the adjusting screws soldered in place.
001 011.jpg

The three main parts for one horn laid out.
001 012.jpg

All six of them assembled, it looks like I may have to do a bit more work to the two on the right.
001 013.jpg

The first of the horn gaps cut out before the two frames were split.
001 014.jpg

The two frames split and two more bearings fitted, I've still to drill the holes for the safety chains. After this I'll start work on the spacers.

Hello all,



starting work on the spacers, the spacers laid out in their approx. positions. S3 & S5 will be modified when their in the frames and S4 will not be used.
001 016.jpg
Checking that they all fit in place.
001 017.jpg

Tack soldered in position using 188Deg. S1 is not fitted just yet.
001 018.jpg

From the outside after cleaning the excess off. I don't tend to clean off the tags on spacers if they are on the tabs as these will come off when I take the tabs back to the frames.
001 019.jpg

Getting ready to fit the second frame in place using one of my alignment jigs.
001 020.jpg

The second frame in place using my alignment jig and two dummy axles.
001 021.jpg

The frames all soldered up and the footplate brackets soldered in place, most of these will have the centres removed later on.
001 022.jpg

The same from above rear, it looks like the frames are bent in this photo but their not honest.
001 023.jpg

S3 & S5 modified.
001 024.jpg

The next jobs for today are making up the coupling rods, then starting on the horn guides Etc.

Hello all,

as I mentioned in my last main post I was going to do the coupling rods and use them to check the wheel centres. As they come from the etched sheet, unfortunately these have a very large etch cusp on them so cleaning them up will take a bit of time.
001 025.jpg

All of them soldered together and in place on my frame jig that had been set up using the axle holes. The rods were spot on well done M.M. who drew the art work.
001 026.jpg

Getting the front horns ready for fitting, these need a bit cutting out of them to clear the brackets for the brake lever.
001 027.jpg

The half etched square is where the bracket fits on the frames.
001 028.jpg

Checking the hight of the front of the frames after the horns have been fitted,to hold the frames in place I use a 1Lb weight.
001 029.jpg

All of the horns fitted in place, all of the axleboxs will be removed and checked for movement and any tight spots sorted out along with any tags that need sorting out.
001 030.jpg

What to do today? Fit any parts that can't be fitted after the frame over-lays go on and a clean up.

Hello all,
this could be a bit of a long one so get a brew. Horn blocks out again and safety chain attachments added.
001 031.jpg

A close up of the attachments.
001 032.jpg

Getting ready to fit the retaining bars to the horn guides.
001 033.jpg

and in close up.
001 034.jpg

Some of the springs before grit blasting.
001 035.jpg

After grit blasting.
001 036.jpg

The front springs along with the brake arm brackets.
001 037.jpg

and removed from their sprue's
001 039.jpg

The rear springs in place for this I used 188Deg. solder.
001 038a.jpg

The brake arm brackets in place.
001 040.jpg

Along with the brake arm, this was a bit short to fit in the brackets so I had drilled them out to 2.5mm and added some brass tube. They also needed a small amount removing from the face that the spring casting fits in front of.
001 041.jpg

The front springs in place along with the round front strengthening bar.
001 042.jpg

The main parts for the cylinders laid out. This is one area the does require a bit of work doing to it, as four holes need opening out and four need reducing. Along with the slots for the slide-bars.
001 043.jpg

All of the holes drilled out ready for some parts to be fitted, I've bent the rear of the cylinders to shape before fitting the reducing rings for the valve covers, it's just makes it easer to bend them to shape when the front and rears are still just flat bits of N/S.
001 044.jpg

The reducing rings in place in the rear of the cylinders, the nearest one having been filed flat to the face. I prefer to do it this way rather that try to turn them down to the correct step as my lathe only has 0.5mm steps on the main carriage handle and I've not got around to making a micrometer stop for it yet.
001 045.jpg

PS. good to see some of you at Cleck. on Sat.
