Ray are the glues you mentioned comparable to Tenax 7R which has the chemical reaction to styrene that welds or melts the two together. This is what I have used. I'll have to try your stuff too, I like the option of the thicker glue. 

 

This is coming along nice. I like to not look for awhile then let it all sink in. I like the structural of the foot boards. I seen some large scale guys use the plastic band straps that are used around boxes for foot boards. When it's painted it looks just like the real material. The body work you done on the boiler is awesome.

 

I have several HO scale Rivarossi loco's made in Germany. Their very heavy but good torque & nice detail. I have always been a fan of the steam era amazing machines in their day. One of my other fascinations with these are the Tenders. A lot of people ignore them but there are many designs for not only the engine but for the local. One of my favorite tenders is the Vanderbuilt, do you have any of those? You got me wanting to unpack some of my engines just to look at them  :D  :thumbs:

I'm not familiar with Tenax 7R but it sounds like it works the same way as what I'm using.

 

There are severial Vanderbuilt style tenders in my collection on locomotives that would have been oil fired instead of coal fired.

So far, I've scratch built or "kit-bashed" all of my locomotives and I have also scratch built the tenders for most of them.

Some of my locomotives have store bought tenders behind them.

I will be making the tender for this one using parts from the AHM tender and styrene.

Bending brass tubing to form the steam supply pipe for the steam cylinders on the rear chassis.

SAM_0453_zpsaubsaiyt.jpg


Here is the finished supply pipe.

SAM_0454_zps1dpwsrkp.jpg


And how it looks fitted to the boiler.

SAM_0455_zpsaggvojdo.jpg


A piece of styrene is wrapped around the center of the supply pipe for the "T" pipe fitting on top of the boiler.

SAM_0457_zpskbicd8gn.jpg


Side view of the steam supply pipe.
I also finished the lower extension of the fire box at the rear of the boiler

SAM_0459_zpshgqdskto.jpg


I cut the steam dome and the sand domes off the boiler of the AHM plastic engine.
Originally I cut these around the mounting flange.
However, the thickness of the plastic boiler made the mounting flanges to thick.
So I trimmed the mounting flange off each dome and glued a thin piece of styrene to the bottom of each dome.
After they dried, I trimmed the mounting flange to size.

SAM_0452_zpsjuu0i7aw.jpg


The domes are not glued on yet but this is how they will look when they are mounted.

Working on the back end of the fire box and the shelter for the fireman.
I cut the back of the fire box off the plastic AHM engine to use on this engine.
It is fastened to the back of the brass fire box with two 0-80 machine screws.

SAM_0463_zpsng68yflm.jpg


Then I made a pattern for the fireman's shelter out of cardboard.
This pattern was transferred to a piece of styrene and then cut out.

SAM_0464_zpsny9rjq0z.jpg


This shelter piece is then wrapped around the end of the firebox and glued to the floor and the sides of the plastic fire box end piece.

SAM_0465_zps4iirtjqa.jpg


Once that glue was dried, I then cut a piece of wood to the shape of the roof and clamped it in place.
I let this set overnight to form the styrene to this shape.

SAM_0466_zpseumbk73q.jpg


Then I fit a piece of styrene for the front panel and glued that in place.
You can also see that I have put a line of "rivets" along the front edge of the fireman's shelter.

I wrapped the boiler cover retaining straps on the boiler and  mounted the steam dome and the sand dome on top of the boiler.
The two sand pipes are run down each side for the rear chassis.
Three steps are mounted on each side of the boiler to climb up to fill the sand dome.

This engine had an air compressor pump on each side and four air tanks on top of the firebox.
The air pipes are run between the tanks and the pumps and two air lines are run up to where the cab will be mounted.

The three steam pressure pop-off valves are mounted on top of the boiler right behind the sand dome.

How did you make the rivets on the cab ? Tom

I have a nice rivet press but it is packed away with the rest of my train stuff.
So I decided to make up a temporary rivet press using my drill press.
First I turned a piece of steel rod so it has a small bump on the end.

SAM_0386_zpsgkflg9pn.jpg


Then I drilled three small holes in the table on the drill press.
The one on the left is for brass and the other two are two deeper holes for working with a plastic sheet.

SAM_0383_zpswngg19vl.jpg


The small steel rod is held in the drill chuck and a back stop is mounted on the table top for an edge gauge.

SAM_0384_zpsx8delshm.jpg


Here are the test pieces in brass and plastic.

Boy Ray, I have missed a lot being off the site for my surgery. Wow you have really been making headway on this engine. Looking great again. :thumbs:

Making the cab. .....
Using .060 thick styrene sheet for strength, I drilled two  holes for the area that fits around the boiler.

SAM_0487_zpsqhpdyzd1.jpg


Then the front and rear panels are cut out.

SAM_0488_zpselqmskop.jpg


And the window openings are cut out.

SAM_0489_zps0khvlrkl.jpg


After doing the same for the two side panels, the pieces are glued together to form the cab.

SAM_0492_zps1hih1g9r.jpg


The cab roof is cut from .030 thick styrene and the "rivets" are pressed in from the back side.

SAM_0493_zpsdt1xytmn.jpg


Here is the finished roof panel with the rain gutters and the vent cap installed.

SAM_0494_zps7uiqcrg1.jpg


How it looks mounted on top of the cab.

SAM_0495_zps7udzvxpi.jpg


I cut two side panels out of .015 thick styrene and put the rivet pattern in each one.

SAM_0496_zpshgsldpz0.jpg


These are then glued onto the sides of the cab.

SAM_0497_zpsvt1wnwgc.jpg


The window frames are glued in place and the trim is put on around the doors in the front and rear panels.

SAM_0498_zpsqfju1v9q.jpg


How it looks mounted onto the boiler.

 

Left side. ....
