A row of quarry workers cottages

Post by Trevor Thompson » Sat Jul 16, 2022 3:32 pm

Following on from introducing this model under "The Railway in the Valley of the Mill". A row of cottages based on the row in the Welsh Slate Museum. Because my printer bed is small - 150mm x 150mm x 150mm, and it is difficult to use the full height when printing in ABS (without introducing splits and distortion) it is designed to be printed in multiple parts.

Just for completeness the solid model:

and the first two parts printed and bonded together with acetone:
IMG_2279.JPG
The first two parts are the front of one cottage. At least they are the outer "skin" of that frontage, printed as a lower and upper section. There is an inner framework which I will show when the next one comes off the printer. The inner skin creates a thickness to the walls which represents the thick walls which real stone buildings have.

Two cottage fronts are being bonded together in the next view:
IMG_2280.JPG
The thickness of the walls should be visible in this photo. There is also one resin printed window in place in a downstairs window frame. I'm using a length of alloy angle to try to ensure that the different components go together in a straight line.

I am printing 4 front walls, one after the other, before I print 4 rear walls in the same way. The fronts and backs are just mirror images of each other. IE the doors are on the right of each cottage on the front and on the left of each cottage on the back.

This is the frame for the side of one cottage:
IMG_2281.JPG
It came to be like this because my first attempt with it solid and in one piece (well two really if you go back to how its printed as an upper and lower section) came out with lots of distortion. It was too tall (thick) to print in ABS without distorting. So I split each side into an outer skin 3mm thick and an inner frame which is really just a reinforcement to keep things flat when its finished. It also gives the "look" of a thick stone wall.

I now have four fronts printed and assembled into one long wall:
IMG_2283.JPG
I have created the dividing walls between each cottage in a skeletal form - a frame without a skin - and the first is printed and attached:
IMG_2284.JPG
from the side to show the actual internal dividing wall and:
IMG_2285.JPG
from the front to give a better feel for the size and form of it all.

I'm now printing the backs of all the cottages and the rest of the dividing walls.

Clever stuff Trevor, looking very good indeed.
The best things in life are free.... so why am I doing this?

That is looking good Trevor. I wasn't too sure about the double thickness walls to begin with, but that last shot shows it really well and it adds to the solid look that real cottages show, so hats off to you! :salute:

The row of cottages is developing into a pretty large model. Both back and front created and assembled onto the skeletal end walls:

It is a slow process, but here is the complete building framework. All the cross walls added and the roof frames in place:
IMG_2300.JPG
and the first end wall with its outer "skin" added:
IMG_2299.JPG
I will have to be careful not to let the size of the stones change as I add the detail to the surface of the building in future. Each stone was individually drawn and "pulled" by the way. I am sure I will find a more efficient way to do that without creating issues with the mesh.

and a pile of doors and windows from the resin printer:

Only the roof and chimneys to go!

What I reeeealy want to know is, with all the drawing and printing of cottages and windows etc, drawing and printing of figures plus playing with the software, not to mention huge amounts of 12":1ft civil engineering, how do you find the time to sleep and eat???? :lol:

Excellent lifestyle choice Trevor, television is such a waste of valuable time.
Everything I want is available on-line when I need to know.

I have started to build the roof. The first 8 sections which make up one side of the roof have been bonded into place:
IMG_2308.JPG
I have been discussing the shape of the cottages with Dinah and Simon. The consensus is that the cottages may be a bit narrow - and the doors certainly LOOK tall and narrow. When you measure the width that is within the normal range of door widths (if on the narrower end of the range) so I can live with that. However it has become obvious that the pitch off the roof is too shallow. So reluctantly I have decided to modify it.

I have drawn extensions to the roof frame, an extension to the end wall "skin", and stretched the roof sections to fit the new shape:

At least it is only one side of the roof which has been printed. I will add a stonework surface to the wall extension which I hope will disguise the changes. So back to printing the modifications.

The roof profile now looks a lot better:
IMG_2333.JPG
I will always be able to see the join in the end walls - but the outline is no longer glaringly wrong!

Just as an aside I have painted the walls with white paint intended for house walls. It took 3 coats, and the intention is that it looks like "white wash".The cottages in the museum are set out as they were in different eras - and the left hand two represent earlier period. Whitewashed walls and dark brown paint on windows and doors. Typically Victorian I suppose. ( I remember my grandfathers outbuildings being whitewashed - and having to be careful not to have it rub off onto your clothes. ) So with the walls painted I can prepare the windows and doors and fit them.

So back to printing the roof itself.

Yes those roofs look much better. The lower roofs made the buildings look like warehouses. Now they look very visually appealing, and proper.
