Installation of the D1124 Detailed Oil Conversion Kit for the Mantua Slantback Tender

Before starting on this, let us say that any custom detailing project will take a certain amount of kit-bashing skills, tools (drill bits, files, etc), and patience.  Our goal here is to do the best we can to point you in the right direction.  As you go along, you may want to modify a step or add a part to meet your individual desire.  That is what custom model building is all about.  At this point, we have not listed certain specifications such as exact measurements or drill sizes, but that should be fairly easy to determine by looking at the parts in the kit, and checking the placement from the following pictures.  Good luck with your modeling!

You will want to sort out all pieces prior to beginning.   Where pieces need to be glued, I recommend using LocTite brand super glue gel.  I've used many types and brands of cement, and this one works the best for me.   Size up the oil bunker top to get an idea of how much material will need to be removed from the tender (fig. 2).  A sander works best for removal of coal, but other methods can be just as effective.  Be careful to only remove material down to the sides of the coal bunker (fig. 3).  Test the fit on the bunker top and adjust with a file or sand paper before securing.

When the bunker top is well-fitted, apply a generous amount of Super Glue gel on the surface of the tender area to be covered.  Press on, removing any excess glue quickly with a cloth.  Hold firmly for until the bunker is set in place.  I like to put a small clamp on the unit until it sets up well (fig. 4).  After the bunker top is set, mark and drill a hole for the hatch using a 1/8 drill bit (fig.5).  Apply a small drop of glue gel to the peg on the hatch and set in place lining up the hinges in the proper position (fig. 6)

Fig. 9 - Drilling up through the tender for marker posts
Drill 2 small holes for the flat handrail posts on the back of the tender.  Mount both posts, then use the brass wire to make the coupler lift bar for the back (fig. 7 & 8).  After you get the coupler lift bar completed, put a very small drop of glue on each post, wiping off all excess, to hold the bar in the proper position.  This will hold the handles on each side in the proper place.  Figure 8 shows approximately what the bar should look like when finished.  Taking a small drill the size of the marker post pin, carefully drill up through the bottom of the back tender platform on both sides (fig. 9).  Be sure to drill in the same spot on both sides.  This will be easily done by placing the drill next to the corner rib on each side.

After drilling the holes, put a drop of glue gel on the posts and carefully insert into the holes (fig. 10).  Next, take the brass ladder stock and carefully bend a hook in the end to simulate the ladder top (fig. 11).  Drill a small hole in the top of the bunker for at least one side, and one on the bottom (fig. 12).  Trim the other sides down a bit to fit flush with the platforms.  This will take some sizing and careful fitting.  After the fit is made, apply a drop of glue gel on both ends of the ladder that go in the holes and insert.

The completed ladder should look similar to that in figure 13.  After this step, your tender kit will be almost completely installed.  I normally clean the unit with rubbing alcohol using a small brush.  After drying, it is ready to paint.  Paint the unit per your choice.  When the paint is cured, apply the jewels in the marker posts using a small pinpoint drop of glue in each cavity of the marker post, and carefully set the corresponding jewel in place.  Red jewels go to the back, white to the sides.  The final step is to place a drop of glue into the cavity of the tender light and set the larger jewel in place.  With this, your tender is completed.
