DJ Dangerous Posted June 14 Posted June 14 The whole digital sculpting concept is mind-boggling. Amazing to see how it works. And that mill is a beast! 1
Mayner Posted June 23 Author Posted June 23 More workshop than layout topic today. Successfully printed the facades of some of the low relief background buildings first planned approx 14 years ago. Terrace of 3-4 houses . The windows/doorway originally etched in 2012, the intention to use Wills Flemish Bond material sheets in combination with etched window/doorways and lintols. The Dublin Port layout reserrected in a different in OO about 10 years later with some of the buildings in 3D printed form. Windows/doorway placed temporarily in the openings to check fit before carrying out final (hopefully) adjustments to the 3D model & print set up. While brick coarsing, opening, cill, lintol and parapet lines came out well some 'interesting' distortion along the party wall between adjacent buildings & de-lamination between layers in one corner (joy of resin printing) Some tweaks to the model (digital reinforcing) to reduce distrotion and delamination resulted in some improvement to the building on the right! The pitched roofs & chimneys on this terrace are hidden behind a low parapet when viewed from street level! Next challenge will be painting and weathering the brickwork. 6
Mayner Posted July 3 Author Posted July 3 Three usable facades glued together after some fettling to the construction joints with a large mill file! Now ro read up on Iain Rice's advice on painting brick buildings, but may go for more of an overall effect as mortar joints and difference in colour/shade between individual bricks unlikely to be noticeable in background/same for maltings building. Designwork substantially complete on a larger house that completes the terrace. Still got to add floor & internal walls to strengthen the model and an Ionic Portico to the doorway. There are another pair of buildings to be added. I'll probabably include pub for those that lived and worked in the neighborhood. As a kid my Mum used to take me to visit her aunts that lived in a house in North Richmond St, their landladys husband was a cattle drover who sometimes drove cattle along the North Circular to the Docks into the late 1960s. Years later in my teens I attended the MRSI clubroom almost weekly as a teenager and waited for the 23 bus home close to the canal and railway bridge on Ballybough Rd. 6
Mayner Posted July 12 Author Posted July 12 Mixture of physical and digital modelling. Preparing some of the building in the terrace for painting/weathering. I have glued the three building on the right together primed and sprayed with brown aerosol (my version of CIE brown wagon paint) and filled & touched up unsightly joints in the party walls. Brickwork joints in the building on the left flooded with a cream paint to represent the mortar joints and brickwork overpainted with a shade selected from a photo of the prototype and a paint colour chart. I used a colour chart and matchpot from Resene a New Zealand owned paint & decor company. The buildings on the right and left were overpainted with the same colour one on a grey the other on a brown base, I've forgotten which is which and managed to 'disappear" the two test pots I bought yesterday Finished the CAD work for the final building in the terrace, main difference is that I extended the brickwork and plinth onto the gable. Currently the prototype has a rendered finish and pitched roof gutters visible at eaves level and bay windows at groundfoor level, out of character with other buildings in the terrace and the adjoining terrace on Ballybough Road. It looks like the building was originally to a similar design/character to the other facades in the terrace and along Ballybough Road, but re-built parapets removed, possibly roof framing replaced and external walls given a render finish and bay windows added. Interestingly window, door locations and general proportions are similar to other facades in the terrace and on Ballybough Rd. I'll probabably model the pitched section of the roof and chimneys in semi-low relief and on the backscene as the buildings are only 30mm deep> 9
Mayner Posted Saturday at 10:56 Author Posted Saturday at 10:56 Trial fitting of the terrace after painting the brickwork. Facade was first sprayed with etch primer and brown aerosol I had in stock, brush painted with a Humbrol grey acrylic working paint into mortar joints wiping surplus paint off face of wall with kitchen towels, and stippled/drybrushed face of brickwork with a 'matchpot' acrylic selected from a local 'home improvement' store. I selected a 'near match" between a Google Earth image of the building & paint colour charts. General view of terrace from railway/dock, buildings from Google Earth views of Sackville Gardens, Ballybough-Drumcondra depending on whether your a buyer/renting ot selling/landlord. Building on right is a temporary while printing the permanent one . The retaining walls are Wills Coursed Stone, the wall in the background painted/finished more than 10 years ago using similar techniques with the last of my stock of ( American) Floquil modelling paint. Water crane is a fairly ancient (early-mid 80s)n Mikes Models casting fairly close to a MGWR crane, Mike once produced a large range of water cranes and other steam era castings. The 'view from the bridge' so to speak looking towards the maltings based on the former distillery at Grand Canal Dock with its distinctive stone and brickwork, the yellowish brickwork of the distillery buildings should make an interesting contrast with the redbrick terrace. Looking back towards the road bridge and Tower Building, I am planning to add another low relief house between bridge and backscene and add the water tank/parapet to the tower building. I originally to form the tank sides/parapet in etched brass when I started the building around 2012, but probably simpler to produce a 3D printed model these days. The 'corner building" after curing, temp supports still in place apart from one window (I just removed supports.) printed in e-Sun waterwashable resin ( approx €15.30 500ml relatively cheap in comparison with other brands of resin). Seems to give reasonably consistent results, main drawback appears to be brittleness and some distortion, I print at the resin manufacturers default settings. 8
Patrick Davey Posted Saturday at 17:36 Posted Saturday at 17:36 Lovely stuff John - always enjoy these updates.
Mayner Posted 15 hours ago Author Posted 15 hours ago Re-thought the building between the overbridge and backscene on the fiddle yard approach and decided on a semi-low relief malthouse to balance the Tower Building rather than a pub! Progress after 2 evening (approx 4hrs total) with Fusion, cills and lintols to be added and decide on how I will form the windows, Wills parts or 3D printed. Section below street level will be modellerd using Wills Coarsed Stone sheets. I first produced a 3D model of the basic structure complete with window opes before adding the brickwork not unlike a building with in-situ or pre-cast concrete walls & brick cladding (without the cavity) Set out from one corner to get the header-stretcher-header pattern on the first course-then 3/4 stretcher (King Closer)-header-stretcher on the second coarse. (wall & base hidden in view Then added header-stretcher-header-stretcher-header for the second brickwork module then, copu and paste for the rest of the 1st two courses! Individual modules now combined and selected for copying. Progress to cill height and window opes set out. Coarse template beneath ready for copying. Distillery buildings at Grand Canal Dock the inspiration for the models. In its orignal form the Tower Building in the background was a landmark 'signature structure' in photos of Grand Canal Shed and the approaches to Westland Row, Pearse Station. 4
