Creative and unique as always. Great build.

The hose reel has been painted and the frame and supply piping has been added.  There is a small valve and lever just before the elbow in the plumbing that will turn the reel off and on for water.  The frame work for the hose reel was made from sections of the ALF frame and some strip stock.  Pretty much the way a Hannay hose reel would be made.  The pump is also painted and mounted on the frame, located so that the suction can be extended through the pump panel sides.

I used 18 gage electrical wire for the booster hose.  The wire surface was rubbed with steel wool to eliminate the writing on it.  At the end is a combination nozzle that was supplied by Don Mills Models. The end was painted flat black.  The connection to the "hose" is a piece of aluminum tubing.  This is another area where the AMT kit is in error.  Black booster hose went out with horses and steamers.  Nearly all booster hose is made of a reddish rubber and can be had in either 3/4" or 1" sizes.  The size of this hose would be 1".  The second error is that they placed the 2-1/2" nozzles on the end of the lines.  The kit supplied nozzles are for larger hand lines and are shown with handles.  They should not be used on a booster line.  After the body is painted and the booster reel is set in place the line will be formed to look like it is draped over the roller guides.  The latter have not been made up yet.  The "V" shaped opening on the right side of the pump panel is for a step.  Note also that the two vertical slots and the two slanted slots are for the handles of the discharge gates.  They will be opened up some before the panel is finished and mounted.

More great scratch building, Charles.  Never having been around any kind of pumper trucks, how did mechanics access the pump for any needed repairs?  Looks like close quarters all around the pump enclosure.

Depends on what was necessary to repair it, Brian.  If packings needed tightening, they could crawl under the truck to get at it.  More sophisticated repairs would mean removing all of the intake and discharge caps, and other small things and then unbolting the entire panel from either the right or the left.  They are typically designed to be removable.  The officer's side of the truck has a much simpler panel and could be removed much more easily.  Also the operator's panel was made in two pieces so that the upper half which contains all of the gages could be left in place.

Very nice! I wondered the same about accessing the internal parts. There was a large fire apparatus builder Salsbury close by till they moved. E-one took over the plant for awhile, but since moved

Here's a Saulsbury rig that was built on a Simon Duplex chassis for the City of Miami, FL.  Built for Bob Milnes.

A few things done to the list that will conclude the project.  Grab handles were added to the cab.  Soft wire was used and bent to form the handles.  The ends were drilled through for common pin mounts.  The pin heads were ground slightly smaller.  The guide roller was added to the top of the body next to the hose reel.  The base will be body color.  The upright rollers will be chrome painted with a Zoet pen. 

Drive shafts were made of 3D printed U-joints and some aluminum tubing.  The U-joints come in two pieces with one open so that it fits into the center slot of its other half.  They can be positioned independently and the shafts slide so that the U-joints are secure.  Then a drop of CA is put at the end of the larger tubing to secure the smaller one and keep it from sliding after the U-joints are in position.  All will be painted in good time.

[Chariots of Fire]

Little things getting done while I wait for the temperature to get a bit warmer.  Hood latches added and a light bar is added to the roof.  I found this one in the stash and it's a bit smaller than the old one that came from the old Dodge van kit.  The hard suction hose trays are painted and are ready to install.  Brackets will be made of some strip aluminum and common pins to hold the suction pieces in place.  I dug out the ladders from the AMT kit and cleaned them up.  Be sure if you use them to scrape away the parting lines from both the outside and inside edges of the rails.  I also added some small strips to the base of the main ladder.  These pieces are intended to dig in when the ladder is set to keep it from slipping.  The roof ladder has two hooks at the top.  They are intended to swing out 90 degrees to the plane of the ladder.  When it is used, it is slid upside down up a roof and then turned over to allow the hooks to dig into the opposite site of the roof.  This keeps the ladder in place and provides a stable place for a firefighter to work.

The hose reel is done and ready for mounting once the body is painted.  The hose was positioned so that the nozzle will match the location of a simple clip on the face of the pump panel.  The guide roller is done but needs to be painted.

Fire apparatus of this era would have used either wood or aluminum ground ladders.  I will choose wood in this case.  Many times equipment was simply transferred from one piece of apparatus to another.  And some departments simply like wood ladders.  San Francisco, CA is one of those even today and still has its own ladder making facility in house.  Wood ladders don't conduct electricity; aluminum ladders do!  The ladders represented are a 24' single extension and a 14' roof ladder.  The extension ladder will need a halyard and pulley after they are painted.  The top of each ladder will be painted white and the base of each will be black.

I think Charles has illustrated a great point in this last post; a thorough knowledge of your subject allows the level of detail that results in accurate models of exceptional quality!

[Chariots of Fire]

When I first started this post I promised to include how to use aluminum foil for treadplate in certain areas.  The following will show some of where the foil has been used and a bit about how it is done.

This is a little dark, I know but at least I can give you an explanation.  The piece of foil has been cut to width for the area just below the hose bed.  It is lying on top of a piece of plastic treadplate.  To the left is a pencil with an eraser which was used to press onto the surface of the foil to get the impression of the treadplate underneath.  The foil needs to be aligned with the pattern on the treadplate so that it will look right when it is mounted.  It takes a while to do the impressions but it is easy to do.  Make sure the foil does not slip once you begin the embossing or it will spoil the pattern.

 

The foil has been put in place using CA as a glue.  

The embossed foil is now place with CA glue.  A word about the foil.  Use a new Xacto blade to score the foil against a straight edge.  Glide the blade over the foil lightly but not with the immediate point.  Lay the blade down a bit and let is score the foil a little at a time.  Once it is free, you will have a nice straight line which will be the bottom edge in this case.  Once the glue has set use the Xacto blade again to cut the foil.  Punch through the foil against the edge and at the center.  Do not start at the end.  Work toward the ends from the center going each way.  Again the cut will be neat if you lay the blade down a bit.  Do the cutting away from the foil edge so it does not lift up.  The results will be as you see below.

I'm also doing the edges of the running board, the bottom behind the rear wheels and the edge of the rear step.  I start by cutting a thin strip of foil the same as before.  One edge needs to be nice and straight with no tears or uneven places.  The foil is again laid down on the treadplate and embossed with the pencil eraser.

Here's the strip of foil before it is embossed.  The Upper edge is straight and clean.

The foil has been glued to the running board edge with overhang on the bottom.  Don't try and precut this edge or even the length unless you have an enclosed space like the first foil above.  It can be easily trimmed afterwards.  Keep the glue away from the top edge and don't let it ooze out.  Two part epoxy will also work well in attaching the foil.  It gives you a lot more working time but you have to be sure that it sets up well before attempting to trim it.

I did the rear step and the sides in three pieces.  The sides were done first using the same process at with the front running board.  But in this case I bent the embossed foil over the beveled corner and then cut the excess off.  I did the same to the other side leaving the center of the running board to last.  After the foil was trimmed I gave the upper surfaces a coat of Model Master silver.  I prefer the dull side of the foil on the outside.  I think it looks more in scale and less toy like than if I had used the real shiny side.  The silver paint is a close match.

The right side of the truck is complete as well.  The pump panel is still in need of paint.  It will be body color with some chrome trim, intake and discharge caps.

I worked on the pump panel in the last couple of days.  I chose flat black for the color and highlighted it with several pieces of chrome.  The top part of the panel is a section of the pump panel from the 1/32 scale Mack snap kit.  The gages are excellent.  I cut a hole in the panel and fit the cut section into it and then gave the gages a light black wash.  There will be some better photos of it coming up.  The Zoet chrome pen worked wonders in several parts of the panel.  In the upper left of the panel is a chromed light for night work.  I used a clear plastic beady eye for it and removed the bead by cutting a hole in the back.  Part of the clear plastic was left uncoated with the upper half chromed.

In the meantime I'm going to use the lights from the front of the Mack for the tail lights and directional lights.  The directionals are arrow shaped with the tail lights round and above.  Tamiya clear orange will be used for the directionals and clear red for the tail lights.  The bezels will have to be cut from the grill first and reshaped in the back for mounting.  The nice Federal Q siren will be salvaged for the future.

Interesting to follow the steps using foil to replicate tread plate.  In those areas where you fold the embossed foil from a flat step to cover an adjoining edge, is it difficult to bend the foil and not damage the embossing.  Thanks for showing this technique.

[GLMFAA1]

Great 'how to' and if I may offer some other tips. I use spray adhesive to adhere the foil to the project. The other tip from the late Bill and Andy is after you emboss the foil is to coat the  back of the foil with white glue to fill in the dimples so they don't collapse.

Getting nearer the end of the build.  The last thing to do will be the hose load.  Still a few details left to go.  But here it is as of tonite.

This rig is going to be Eagle Hose No. 3.  Wonder why!!?!  😎

[GLMFAA1]

I can guess the ALF eagle on top of the roof. I used the bell from the Aurora 1/32nd pumper for smaller units. This modified Revell 57 pick up was done years ago matching the AMT ALF pumper body. To back date it I did the sides with the front fenders and used the Aurora ALF pump panel to reverse the operators side. Flipped hard suction and ladder positions,wound carpert thread around hard suction for age effect.

Lemme guess:  Because Eagle Hose No. 2 and Eagle Hose No. 1 were already taken?

Well, yer both right!  😁

More great info on the foil.  Do you use the regular aluminum foil or the thicker stuff?  Reynolds makes both......

Just regular old foil, Warren.  The thicker kind would be much harder to emboss.  And to answer the question about folding it sharply at corners that is further up on the post, it can be done but the difficult part would be to make sure the fold goes exactly with the pattern otherwise it will not look good.  On the other hand it does go over rounded corners quite well.  Here's the results of doing that on the M-20 prime mover I did a while back.  There is no distortion of the pattern either.  Note also that foil was used on the face of the running board.  The top is regular plastic treadplate.

In the photo above it was used to cover the fuel tank.  Again, a rounded edge.  The foil was laid on first at the outside edge and rolled over the top.  In this way I did not have to worry about cutting the edge and getting glue everywhere.  Once the glue begins to set at the outside more glue can be added as you move toward the back.  Lot less messy that way.  It does necessitate being careful not to fold the foil or crush the imprint during this process.  After the glue dries it is perfectly hard and not susceptible to damage.

[Chariots of Fire]

The detailing of pieces to be mounted on the body are getting close to being done.  Today I worked on the hose loads.  Engines of the day of this rig normally carried two or three different sizes of hose.  Working lines of 1-1/2" and 2-1/2" and supply lines of 3".   The bed is divided into sections for each size.  On the left will be the 1-1/2" working line with additional hose of the same size below it.  There is a board separating the two layers that was made up once the first layer was in place.  The hose used then was rubber lined with a double cotton jacket on the outside.  Today most hose is synthetic.

The photo shows the material to be used for the hose along with a piece of plastic that will be painted gray.  The hose is sewing elastic and comes in two basic sizes; 1/8" and 1/4".  It's about as close as you can get in material that not only looks like hose but is of a reasonable size.  It comes in packages of about 3 yards so there is quite a bit to work with.  It's white and has to be stained.  I found that a good color is Tamiya XF-60 Dark Yellow.  Wetting the brush and dipping it into the paint is sufficient to coat the elastic.  I generally use a piece of aluminum foil taped to the work area so that things don't get messy.  Once that is done several pieces are snipped into short lengths and glued in half like the ones in the photo.  More on this a bit later.  Got to go and take the dogs out!😆

Fantastic scratchwork here. The finish is top notch! 

[hct728(Bob)]

Awesome progress and results! Love the foil tips, getting those bends with sheet stock is impossible, and I particularly like that rounded treadplate edge on the M20, complete with wear through the paint, inspired!

Good tips from Greg too, lots of experience here

As always Charles, simply outstanding modelling!!!
