Hello all,

 

back on with some of the under frame bits.

The starting parts for the brake gear.

post-8920-0-10040000-1376743236_thumb.jpg

 

When I was cleaning up the slots in the pull rods, I did slip with the cutting disk, it's not much of a cut and did not bleed that much (I have gone in deeper, and cut right through the nail bed), but it does make you say Ouch or words to that effect. 

I think that I put, blood, sweat and tears into all of the locos that I build.

Up to now I don't think that any of the blood has come from me using the lathe, mill or drill. Just hand tools, blunt tools may not cut the job, but they will cut "YOU".

All of the parts for the tender brake gear laid out (I would have liked brass brakes and hangers), the pins are 1/32" X 1/4" round head rivets.

post-8920-0-08026500-1376743264_thumb.jpg

 

The jig (OK two lengths of wood) that I use to assemble the brake gear. These are drilled at 7' 6" centres.

post-8920-0-35334100-1376743291_thumb.jpg

 

The same as above but with all of the rivets in place. You may have to adjust some of the distances between the holes, to get them just right. When I made the "jigs" all of the distances were taken from one end and that is the end that the square is on.

post-8920-0-59590000-1376743321_thumb.jpg

 

All of the parts now removed from the "jig" after soldering up. The front shafts are soldered up but with some movement, so I can then fit them in place,

Hello all,

 

I'm back again, with a bit of luck I'll finish the tender (more or less) today.

The first job was to sort out the safety chains, to start with I fix the whole length of chain to one of the brake cross beams, then cut the chain so that it will fit on the top fixing. Then all I have to do is cut the next five to the same length, to do this all I do is mount the full length two at a time on the brass rod and hope that I get the cut in the correct place. Then it's fit the split pin (OK a bit of bent wire) in the bottom link.

The chains in place in the cross beams.

post-8920-0-22238400-1376857401_thumb.jpg

 

All of the brake gear in place, setting the first brake in place is done by having the wheel in place in the rear axle-box, and then work forwards.

post-8920-0-29774300-1376857429_thumb.jpg

 

The same as above but from the other side. You can see the top mountings for the safety chain on this side better.

post-8920-0-60814000-1376857456_thumb.jpg

 

A view of the chains from the rear, I may have to do a bit of work one the split pin on the left.

post-8920-0-16000300-1376857484_thumb.jpg

 

The same from the front, a bit of cleaning up still to do, but not that much.

post-8920-0-31768000-1376857598_thumb.jpg

 

All of the inner frames from the side showing the mounting for the chip and pick-up wires on the left. The two brackets on the right are for the speaker (I don't know if they will work).

post-8920-0-72503200-1376857627_thumb.jpg

 

The same as above from the rear and front.

post-8920-0-02983300-1376857656_thumb.jpg

post-8920-0-04641100-1376857666_thumb.jpg

 

Just making sure that it all still fits inside the outer frames.

post-8920-0-51037400-1376857691_thumb.jpg

 

The tender from the rear, after a bit of a clean up and all should be OK. You can just make out the steam heat bag end and its chain. The only parts to fit now will be after painting.

Hello all,

 

after just about finishing the tender, it's back on to the engine, when you last seen it, this is what it looked like,

post-8920-0-05572700-1377122914_thumb.jpg

 

After removing the wheels motor, gearbox and pick-ups it looked something like this,

post-8920-0-09643700-1377123528_thumb.jpg

 

Getting ready to solder one of the centre or rear springs in to place. With the cast springs you have to make sure that the hangers are square and parallel to each other and that the centre hanger will clear the keeper plate

post-8920-0-92643300-1377122938_thumb.jpg

 

The four rear springs in place, you can see the line that I use to help set the top of the hangers parallel to the base of the frames,

post-8920-0-75191200-1377123032_thumb.jpg

 

Most of the parts that will all be fitted at about the same time as the front springs, this is the approx. positions that they will be in the frames,

post-8920-0-64150300-1377123059_thumb.jpg

 

The way that I tend to fit them is as follows. The vac. cylinder on its pivots (you can see the end of the tube that I use),  then one of the brake arm pivots (IIRC I drill these out to 2.5mm), then using a shaft I line up the second one so that it's square across the frames, after that I fit two short lengths of tube into the brackets for the brake arm and set it up central between them and making sure that the brake arm is in line with the cylinder,

post-8920-0-42862800-1377123101_thumb.jpg

 

After that, you have to make sure that the front springs will fit in place. Most of the time you will have to remove a bit from the brackets (you could remove it from the springs), but I tend to remove it from the brackets. You can see that I've started to do it in this photo,

post-8920-0-17606000-1377123121_thumb.jpg

 

After that, it's just a matter of fitting the front springs. A lot of people don't fit the round frame stay as they think it's the brake cross shaft. As you can see in this photo its not. The hole that you can see in the frames is for the front pick-up ( I can see that I may have some fun with that?),

post-8920-0-09943000-1377123144_thumb.jpg

 

The same as above but showing the movement of the brake arm ( no I'm not making working brake gear, Mr. H. Tan. DON'T EVEN THINK ABOUT IT),

post-8920-0-36487400-1377123166_thumb.jpg

 

The frame overlays as they came from the etch sheet,

post-8920-0-28744700-1377123193_thumb.jpg

 

This is the mess that I made of them before I fitted them,

post-8920-0-80824200-1377123219_thumb.jpg

 

One of them fitted in place along with the cast brake hanger pivots, I have counter sunk the holes for the plunger pick-ups so that the collar will fit against the inner N/S frames (doing this just makes the springs a bit softer, with a bit of luck less drag),

Hello all,

 

now lets see working brake gear, how to do it?

post-8920-0-78137100-1377244541_thumb.jpg

 

Step one, hollow out the brake cylinder, and fit a steel disk to the brake rod If we put the electro magnet and spring at the bottom it will work as an automatic self acting brake, with the electro magnet keeping the brakes off.

 

Step two, make a small electro magnet to fit in the brake cylinder.

 

Step three, make all of the brake gear so that it moves and some insulated brake blocks.

 

Step four, wire up to your DCC chip.

 

Must go now, them nice men have turned up with my nice coat with the long sleeves as it's time for me to have my exercise in that nice soft room.

Hello Matey,

 

I have a week off this coming week so we can have a catch up on the land line ;) .

 

Regarding working parts, their is a chap over at WT  who was successful with a working reverser arm linkage, operated by DCC but using a small servo I think.

 

ATB,

 

Martyn.

You can hide a lot inside of an A4 body!

 

Try and do the same with a small loco that has the boiler high above the running plate.

 

I'm writing this with a sick between my teeth as I still have my coat with the long sleeves on, but the nice men in the white coats have let me have a look at a keyboard.

 

I'm still getting fed with pancakes as that is the only thing that will fit under the door.

 

The mad

Are you getting the warm beer through a straw? Or should we be thinking of food beer parcels.... But then again they may not make it to you, or could even interfere with the medication :scared:

Kind regards

Oh yes they were JB, all in the interest of advancement in this great hobby of ours of course!

 

Any chance of any explanatory piccies please.

 

Sorry for the hijack Oz, you know how these topics have a habit of wandering.

Hello all,

 

not a problem Martyn.

 

Back on to the build, the wheels after blackening with Birchwood Casey super blue, the brass centres can sometimes be fun to get the blackening to take. But a good rub with a brass wire brush in the Dremel normally does the trick, after this they will be panted black,

post-8920-0-51786600-1377506332_thumb.jpg

 

I treated myself to a new nail file for cleaning up the narrow slots (Boots £1.80)

post-8920-0-64074200-1377506359_thumb.jpg

 

Most of the parts for the brake gear laid out, 

post-8920-0-12312200-1377506387_thumb.jpg

 

The first side of the brakes in place along with the exhaust steam pipe, I've had to cut the pipe behind the rear spring to clear the gear wheel,

post-8920-0-39780300-1377506414_thumb.jpg

 

and from the side,

post-8920-0-82030800-1377506470_thumb.jpg

 

The front of the exhaust steam pipe,

post-8920-0-78162400-1377506441_thumb.jpg

 

The second side in place along with the brake pull beams,

post-8920-0-79780400-1377506498_thumb.jpg

 

When I was using the slitting disc I did it again!!! different finger this time,

post-8920-0-98994800-1377506545_thumb.jpg

 

The front brake adjusters in place. You can also see that I've ground a bit out of the vac. cylinder to clear the front pick-ups,

post-8920-0-98404400-1377506571_thumb.jpg

 

The same as above showing most of the cross beams and the safety chains,

post-8920-0-33840300-1377506600_thumb.jpg

 

All of the brake gear in place from both sides and front and rear,

The next jobs on the frames will be the cylinders and sand box's.

 

I'm hoping to have this finished for Telford! so I'd better extract the digit.

Should be in weather spoons in the morning mate. Michelle wants to get a parking space close to the exhibition because of the amount of stuff she's bringing for customers so were aiming to get there around 9ish.

I'm looking forward to seeing this county finished and have a good look over it at Telford.

Jeff he means the bar!!! Il be in for 1 or 3 pints but not like last time.
