Sorry for lack of blog posts of late, but business is growing too fast and spend most of my waking moments trying to keep up.   An opportunity presented itself for a last minute weekend getaway this past friday.  Hastily planned, we resolved to go somewhere within a few hours driving distance that we haven't been before - difficult given that we mostly travel within a few hours of our house on our weekend getaways.   Since we like antique stores, I consulted the guides I keep on my desk and found a cluster of antique stores around Hagerstown, MD - Gettysburg, PA.  I'd been in the area before with my son when we used to do father and son Civil War battlefield trips when he was little, but never with my wife and not for shopping purposes.   About halfway there I got recalled that the regional NMRA convention was possibly in Hagerstown, although I also thought maybe Virginia, and I wasn't even sure which weekend.  Well it was this weekend and was in Hagerstown.  So I guess I could have gone, but since it was a last minute call,.....  

We had a great weekend - bought lots of industrial artifacts - ate mostly good food - and saw some new towns and villages.   I stopped at the Western Maryland RR Museum in Hagerstown  late Saturday afternoon after a jaunt down to West Virginia, and bumped into now fewer than 4 model railroaders I knew.   They probably think I've lost a few marbles with my explanation at how I ended up in Hagerstown the same weekend as the convention.

Besides the antiques, the posted photo's show a real neat find in the C&O Canal Park at Williamsport, MD.   This is probably one of the neatest little moveable railroad bridges I've ever found and it cries out for modeling.   The bridge was built by the Western Maryland Railroad in 1923 to access a newly built power plant built on the strip of land between the canal and the Potomac.  The canal was still in use at the time so the bridge had to be built in a way to allow clearance for both the canal boats and the mules and towrope pulling them.  This led to the unique configuration shown in the photos.  Ironically there was extensive flooding the winter after the bridge was completed and the canal never reopened.  The bridge was only raised a few times to protect it from later floods.  The spur was abandoned in the early 1970's when the plant switch to truck deliveries of coal.

Once again I haven't had the time to follow up with additional posts related to my new cutting machine.  Hopefully I'll start to assemble the gas washer I started a few weeks ago,  very soon.  In the meantime......

SPRAY PAINT -  This is a Liquitex can of spray paint I picked up the other evening.   It's the first that I'm using this product line.  I've used liquitex acrylic paints for years and like them.  The spray paint is low odor and while wet can be cleaned up with water.   There are a fair number of online reviews relating to the tips clogging.  This is common with water based sprays I've noticed.   I use a Zinzer water based spray primer and it behaves similarly - clogged tips and sputters if you don't keep the tip clear.    As I use these paints,  I guess I'll figure out how much of a pain in the ass this becomes.   What I do like, is the range of colors, and not typical bright pastel colors, but lots of earth tones and industrial looking colors.  The cans are 12oz, which is four times as much paint as the Testors or Floquil cans.   The price varies, but figure on around $6, which is slightly more than the Lowes/Home Depot Rustoleum or Kyrlon Cans.   I managed to pick up two on sale at Michaels at $5 a can to try.   I bought an industrial light green color that I might use on my port crane, and Raw Umber #7  - This second color is the best I've seen to approximate weathered concrete.  I do also like the Rust o leum light brown camouflage color for this as you've seen in the past, but I think this is slightly better as it's a touch lighter.    You can go online to Blik Art supply and check out there range of colors.

One pass made for rabbets - awaiting second pass

STORAGE -  With the limited space I have in my basement, my scratch building supplies and parts are scattered in many plastic bins and boxes.  I want to get a more organized system as the one part I usually need is the only one I can't find.  Taking a page from the old drawer/bins found in general stores and hardware stores I experimented at my shop with developing a system of mass producing sturdy and cheap storage bins.  I'm using 1/2" MDF for the entire drawer and they are roughly 6"x6"x12",  but really any size could be made.  I want to be able to create some simple plywood shelves that these bins will fit into.    MDF is super cheap, but I also wanted to not spend a lot of time on these things.   The fewer machines and operations the better -  All the cuts were made on a table saw with a regular blade.  The only other tool needed was a brad or pin nailer to assemble the drawers (the glue really holds them together.   The fronts have a notch, or in woodworking as it's known, a rabbet, on three sides, and the sides have rabbets on the two long sides.  The bottom has none.   If measured correctly, the pieces will fit together nice and tight, with the glue doing the real work, and the brads just to hold things together while the glue is drying.   I fashioned some cheap simple handles from poplar using a few passes on the table saw.  Hopefully the pictures tell the story, but if you need more info just drop me a line.
The five pieces of a bin/drawer

Assembled - these 8 took about 2 hours from raw MDF to built
Cheap easy handles.  I might use the handles typical on the old library card catalogs as they have a slot for a label.  

Getting late so I'll cover the Electrical Poles in detail in a future post.  Briefly I wanted a look that you see in a lot of steel mills - tall narrow towers as opposed to your typical hi-tension poles.  The BCH towers fit the bill, however, they were slightly short I felt.  I added a short section from the Walthers electric tower kit to the bottom of the BCH tower and then added a concrete foundation.  Still playing around with the design a bit but here are some preliminary results -

While antique shopping last weekend I came across these two wire rope artifacts and purchased them.  One was a full spool and the Bethlehem one, just a half.   Also note the Penn Central timetable from 1970.  It was a few bucks but interesting reading - good info on trains and also on industrial sidings along routes.  Posted track speed limits were a crawl in many places - too young to remember but physical plant sounds a mess.

I also picked up a few other time tables for $1 a piece - a couple PRSLs from the 50s of local interest and a ACL very nicely done booklet - last station stop Havana.   While at the Reading RR Historical Museum (photos of equipment in earlier blog), I picked up some back issues of there magazine - the Bee Line.  Specifically I picked up the very well done issues (3 part) on Bethlehem Steel's Grace Mine and another nicely done article on the massive railroad tie creosoting plant at Port Reading, NJ

A few models here and there.   At a visit to a Robot museum/store I grabbed a model of the robot from the 70's (I think) TV show Lost in Space.  Also elsewhere, a 1/144 scale Dragon model of a WWII German Railway gun - nice brass etched detail parts and a turned aluminum barrel.   Nice mix of reading materials, trains and models, and industrial artifacts.

Really getting back on the blogging wagon so to speak.  Partially as I'm excited about the Cameo and the potential to assist in making precise parts.  I'm a bit nuts about precision and nothing ruins my day more than having one component slightly off and messing up the whole structure - maybe not ruining it - but something that will bug me every time I look at it.   I did some intricate stuff with the roof truss cutout in Part 2, however, I really see me using it more for basic parts for structures.  I figured a good place to start is the gas washer complex for B-Furnace.   It's a rare mostly free-lanced structure for me - I'm using some measurements of similar washers from HAER drawings, but using photos I took at Bethlehem Steel last year from the deck of the arts center of the washers for either their B or C furnace.   To refresh memories, B Furnace as a dust catcher modeled on a prototype formerly at Central Furnaces in Cleveland (most of Blast Furnace B is based on that prototype, except for the furnace stack itself which is partially based on USS Duquesne #3 furnace) .   There is no precipitator in this complex as both furnaces share a dual precipitator plant modeled almost exactly on the prototype at Bethlehem A furnace and located behind that furnace on my layout.   The washer plant has two main wash towers and two downcomer pipes with additional water sprays in them.   There are multiple platforms on all four towers.  Getting the platforms to match is always tricky and my previous method was to create one and then use that as the template.   This time with the Cameo, I started by drawing the base plate in Silhouette Studio.  I then copied this drawing to use as the basis for all the platforms.  Since everything should be in exactly the same place, I'm hoping the pieces will naturally align the towers and maintain the same spacing throughout.
Initial drawing

In addition to the base and the platforms I created the caps for the upper part of the washers, many platform supports (very small pieces) and rings for some sort of donut ring of undetermined function near the base of the down comers.    I fit the whole thing on a single 12x12 sheet, the max the Cameo can handle.    I started the cut using a sheet of .030.   If I haven't mentioned it before the Cameo uses a cutting sheet - its a 12x12 tacky piece of acetate with a grid that matches the drawing screen.  The sticky nature of the sheet is good when cutting thin plastic and paper and card stock as it holds the pieces in place that are complete cutouts - without it these would fall off and get jammed in machine or even shifted and then cut again.  With .030 and .040 plastic I've omitted using the cutting mat as the machine doesn't cut through the thick styrene so no worries.  I also am feeding in media that is probably a little thicker than the machine is built for so not having the mat keeps the thickness down.
Smaller drawings - less components

For whatever reason, the plastic shifted and the cut shifted out of whack halfway through.  It also had trouble with the cuts close to the edges and with the knife running off the end of the styrene and not being able to get back on.  So I broke the components down into 4 separate files and am cutting them one at a time using 9x9 sheets of plastic.  I reduced the cut window to 6x6, but I wanted some extra room on the plastic to prevent run-off.   Also, the feed roller can only be moved in to about 8" so there would be a feed problem with smaller plastic, however, you can feed smaller pieces of material in using the mat, just not the thick styrene
Cracks and seams added to drawing of base

I thought about it and went back to the base drawing and added concrete pad seams and also cracks.  The cracking was done using the freehand draw function.
Gas Washer base - used some pencil graphite to emphasize the concrete seams and cracks .  Also notice the platform supports - broken off and a strip behind of additional pieces.

I cut out the base on .040 styrene and no problems occurred during the cutting with the 9x9 piece.

The circles on the baseplate basically mark the exact locations of where to glue the towers.

I was able to pick up a variety of plastic in the larger format Evergreen sizes (12x24)    Cut in half they fit in the Cameo perfectly.     I altered the roof truss file shown in part one.  I decreased the size just a little to fit the real estate on the model railroad that I've staked out.  Easy to do and it was described yesterday under the Scale function.  I also duplicated the entire truss to cut out three per sheet.  There is a Duplicate function - learn to use it as it makes things go quick.    Most of my next file I will describe was done using Duplicate.    I also added cross bracing for the sides of the buildings.  I did draw this, and then duplicated into two.  I found it easier to draw this x bracing if I drew a rectangle/square first and used that as a guide for placing my lines.  I later erased the rectangle along with my overlap lines.   Actually leaving the rectangle might make it easier to break the pieces out.  
The revised cut file - additional trusses and cross bracing

I put a sheet of .015 in the Cameo and let it do it's thing.  I wasn't looking at the time exactly but I'm guessing the cut took about 20 minutes.   I set the blade all the way down and set the machine to double cut.  Even with this, the pieces still had to be bent and broken out a little.
Cut sheet of .015 styrene

Once the parts were separated, I used .030x.060 strip styrene to laminate to the truss frames to create an angle steel look.  It is still tedious - I cut and fit each piece and it took about 20-25 minutes to make up one truss.  If I set up for mass production and pre cut all the members it would go much faster.   One side received the strip on all members.  The piece still felt a little flimsy so I added additional strip on the opposite side, but only on the primary structural pieces.   It's still work, but I'm happy with the results and more importantly, the trusses will maintain a consistency that will help keep the entire structure neat and proportioned.   They look a little finer and much better than what I've done in the past with jigs.   I still have many buildings to construct so I'm sure I will be building lots of these.   I will probably go back and do the trusses of the stalled soaking pit building using this method.
Cut out, ready for assembly

For the cross bracing, I used .030x.125 strip between the pieces.  This packs the bracing out to fit nicely between the web of  1/4" H columns .
Final products

My next experiment is using the machine to score thicker, .030 plastic for the gas washer plant for B-Furnace.  I'm basing the structure on photos and some HAER drawings but it's free lanced.  The dimensions are fairly accurate I believe.
