Pam's Flour Build

[Jim Donovan]

Howdy Jim,

The design and build of the intake warehouse look terrific.  The doors are convincing.  I like seeing folks use both the 3D printer and laser.

Have fun,
mike

Thanks Mike;

It has been fun, especially the research, I love the history of that time.

Interesting design pocket for the glass. Where do you get the glass and how do you cut it?

Hi Philip;

I use to get the glass from Clover House, it's called Clover glass however they have been offline due to issues so I researched and found Amazon sells a large microscope cover slip that is something like 22 x 44mm, the same dimensions as Clover, more importantly it is the same thickness about .06mm. I use a number 88 General Tool scribe and with a metal ruler as a guide cut the glass with the scribe. I place the slide cover on a thick sheet of tempered glass for cutting, the hard smooth surface helps with clean cuts. The glass from Amazon is over 1/2 less than cost was from Clover. I still think the clover glass cut a little easier but this new stuff works fine too.I make the pocket for the glass .65mm wide so the glass slide in easy but looks flush.

One of your first posts indicated incoming shipments on some prototype structures being unloaded from canal barges.

Is this source of shipment something that will be represented on the layout? I can't recall viewing the final layout location for the structure in your posts?

I scratch built a canal boat delivering barrels of flour to the mill and hope to have it docking near mill offloading the barrels. This is how it looked next to original setting and will look similar on new I hope.

Thanks for posting that prior picture of the canal packet boat.

I've been a big fan of the later history of the Erie Canal and it's descent, the New York State Barge Canal. In  particular was the development of the steam barge. There will be one featured on the North Coast.

Artitec makes a few versions suitable for 1/87 usage.

Nice scratch build on that boat.

Hi Philip;

Thanks Jim. I already have that general tool scriber so I'm half way there. I always thought a diamond tip scribe was the tool.

A very nice looking vessel. It has that steamship survivor look to it.

So tonight's addition to the warehouse saga is titled, ' in search of an amazing roof, or any roof that fits'. This is a story of missteps, big ideas and poor execution starting with I really did not know what I wanted. My first idea was to have metal corrugated sheeting from BEST glued to a wood base using 3M two sided tape. I decided to also have a cupola to add venting and would in real world house part of grain conveyor.  So here it is (was):




At first I thought it was OK but paint flaked off, I bent some of the sheets ANS it did not fit the building neatly. So I then thought why not have the resin printer print out a corrugated roof in one piece! It was doable according to my measurements, but just. The length needed was a minimum of 240mm and the printer could handle 245. I found a corrugated design on line at the Thingverse.com website. I needed to modify the size, shape, thickness even the rounded corrugated look but it was not too hard. My hope was it would fit snug to structure and allow for it to be removed so you could see the interior. After an 11 hour print job here is what I got:

Other then the fact I missed on the dimensions, shape and had exceeded limits of printer (note the lower right clipped edge) it was perfect, oh brother. 

Not one to be stopped from continuing this running in circles I decided to get creative withe the 3D printer creating an entire rafter system, then having the printer produce a sub roof complete with rafter tails and covered with paper corrugated 3 x 15 panels held in place with 3M two sided tape. Due to size issue I would make the sub roof and rafters in two parts and glue it all together with CA glue.







It was a nightmare to get everything in place, lined up and glued correctly but after toning down the rust you see in above photo it did not look bad, but it was flimsy and did not sit correctly on building. 

So I took the best ideas from each attempt and did the following, first I made the sub roof using .2 styrene sheeting. I then had the 3D printer make modified corrugated sheeting that appears overlapped but nailed in place straight. These panels were glued to the styrene using CA glue spread on the styrene and a fast set spray put on the undersides of the panels. Carefully attaching the parts together I put weights on one side till dry then did the same for the other side.  I have not weathered roof yet but it will be much less then the first attempt. I have also shown the cupola lite so you get an idea what I want from this section. The roof fits well so we will consider this part done. What a meandering mess I made of this but I like the final look.




We will talk about all the eclectic involved next time.

Looks great Jim.  Whilst the first try at it looked good, using what to me looks more like raised seam roofing, I like the corrugated roof better.
Regarding the flaking paint.  I assume you undercoated it first and left that to fully cure.
Otherwise, occasionally paint will still flake off, especially if the material is flexed. or might have been a dud batch.
The lighting setup looks great.

Coming together nicely Jim.....

I love the canal boat.  I always wanted to do a canal scene, after seeing the Delaware & Hudson docks in Honesdale PA.

Howdy Jim,

It's clever to use the 3D printer to gang print the rafters. Pam's is one terrific looking structure and it is not even finished!

Have fun,
mike

Jim,
 Your model builds are coming along nicely. The flour mill and waterfront structures are great.
