M Graff Posted January 7, 2016 Share Posted January 7, 2016 Hi! This is my new project. The Model Masterpieces D&RG 60' Gallows turntable in HOn3. I will, also build the Como Roundhouse to complete the scene. The drive for the turntable will be a step motor with full indexing. It is a system developed by a friend of mine and very fool proof! [] I bought this kit second hand, and it misses the spider gear housing... I will try to make a new by 3D printing it. This is a good plan showing how I will do the drive: (courtesy of Carrie Creek) I started the build by staining and adding grain to the wood. The stain is Isopropyl alcohol and wiper fluid mixed with vallejo burnt umber and black. After it dries, I will lightly sand them to remove the fuzz. More to come soon!

M Graff Posted January 8, 2016 Author Share Posted January 8, 2016 I've come a little further along. The Nut Bolt Washer castings are mostly in place : I just had to see how my biggest locomotive fits : Now its time to spike some rails there. Link to post Share on other sites More sharing options...
M Graff Posted January 8, 2016 Author Share Posted January 8, 2016 Just one more update before bedtime. Filed grooves for the cables. Soldered the wires to the Code 70 Micro Engineering rails. The rails spiked and glued! I use Railway engineering rollee holders. Link to post Share on other sites More sharing options...

M Graff Posted January 10, 2016 Author Share Posted January 10, 2016 You aren't exactly idle, are you No, not really... This build will take a little break (slow down...) in the week to come. I have a deadline on a report on the cultural history objects in the medieval churches in the parish where I work as a curator. Link to post Share on other sites More sharing options...
M Graff Posted January 10, 2016 Author Share Posted January 10, 2016 The base is on its way! :-) 8 mm plywood base. I've glued the piedestal on the top and a piece of pine underneath. I drilled the holes forthe bearings with my pillar drill to get the hole in plumb. The axle will be replaced with a stainless tube. The brackets that holds the tie rods are in place. Had to see how it looks.... The pit wall is to be built using ties. And the pit rail has to be laid. I use code 40 in the pit.. Link to post Share on other sites More sharing options...
M Graff Posted January 12, 2016 Author Share Posted January 12, 2016 Late last night I checked the Turntable and saw that the axle wasn't lining up!?! That despite using a drill press... probably the bushings tilted a bit when gluing them in at first? I made a jig, removed the bushings and lined everything up. Now it is correct! I've also built the turntable pit wall. I used cork up to the pit ring level. Then I glued stained ties up to the top. The ties fit perfectly, I didn't have to trim any of them to fit!

M Graff Posted January 13, 2016 Author Share Posted January 13, 2016 A small update: The cork wasn't totally flat for the pit rail, so I mounted a template/scraper on my centre jig. I then spackled the surface and rotated the template to get a flat surface. It worked great! I made some ties for the pit rail: I glued them using my jig to get them to point towards the centre. As you can see in the picture above, I made another template on the jig. This one were to make the slope in the pit. I mixed some very soupy plaster which I poured in the pit at the same time as I rotated the template. After a minute or two, it began to set. I then removed the template (which had a roll of excess plaster on one side). This is how it looked; I added some thin paint to prepare for the gravel and sand: The piedestal was painted as well.

M Graff Posted January 14, 2016 Author Share Posted January 14, 2016 I have glued the real Colorado gravel in the pit: I have installed the pit rail as well. Code 40 from Micro Engineering. Link to post Share on other sites More sharing options...
M Graff Posted January 16, 2016 Author Share Posted January 16, 2016 Now it's getting close! :-) Mostly done: The things left to do are to install the ring on top for the tracks and the gear, motor and electric wipers. :-) Link to post Share on other sites More sharing options...
M Graff Posted January 20, 2016 Author Share Posted January 20, 2016 I added the walkways on the turntable. I guess the shop workers wouldn't like to jump between the ties... Here is the 2400 step per rotation motor: It is big, but that doesn't matter when mounted underneath the table. Link to post Share on other sites More sharing options...
M Graff Posted January 29, 2016 Author Share Posted January 29, 2016 The gearbox for my turntable is printed! It is drawn in Solid works and the parts are printed in ABS for the gears, and PLA for the housing. Now it is time to install it and see how it works.

M Graff Posted January 29, 2016 Author Share Posted January 29, 2016 Thanks! The reduction is 2:1. A 20 tooth gear on the motor and a 40 tooth on the TT axle. Link to post Share on other sites More sharing options...
M Graff Posted February 1, 2016 Author Share Posted February 1, 2016 I have almost finished the tracklaying for the roundhouse. Next is to build the roundhouse walls. Link to post Share on other sites More sharing options...
M Graff Posted February 8, 2016 Author Share Posted February 8, 2016 I have painted the walls on my Como roundhouse and glued them together. This kit must be a solid 12 on a 1 to 10 difficulty scale.... there are just so many things that has to work out in the end. So far no bigger errors (I hope...)

M Graff Posted February 9, 2016 Author Share Posted February 9, 2016 I have spiked some more tracks. The curved approach track with a 28" radius was made with the wonderful laser cut sweep sticks that a friend in the US made for me. Here are some pics of where in the project I am right now.

M Graff Posted February 14, 2016 Author Share Posted February 14, 2016 I have added some ground cover and some flooring in the roundhouse. Roof joists B/W: Link to post Share on other sites More sharing options...
RMweb Gold PaulRhB Posted February 15, 2016 RMweb Gold Share Posted February 15, 2016 Looks great, I guess any derailments get hooked out through the doors from now on? Link to post Share on other sites More sharing options...
M Graff Posted February 15, 2016 Author Share Posted February 15, 2016 Looks great, I guess any derailments get hooked out through the doors from now on? Thanks!No, the roundhouse is still detachable from the base. :-) Link to post Share on other sites More sharing options...
Giles Posted February 18, 2016 Share Posted February 18, 2016 Superb modelling from start to finish! I should love to see more of this...... Link to post Share on other sites More sharing options...
M Graff Posted February 19, 2016 Author Share Posted February 19, 2016 Thanks! The roundhouse area is getting closer to completion. A whole lot of details and weeds are still to be added.... The roof is currently being covered with tissue paper. Link to post Share on other sites More sharing options...
M Graff Posted February 22, 2016 Author Share Posted February 22, 2016 I have made the smoke stacks and the above roof beams with the stay rods. I have also started the construction of the roundhouse doors. They are very intricate in their design, as they are made up entirely of scale dimensional lumber.... 1" x 3" for the diagonal planking, and 1" x 8" for the framing. I make full height doors like the original had when built, as I want to be able to have taller locos inside the roundhouse. [] Link to post Share on other sites More sharing options...
M Graff Posted February 23, 2016 Author Share Posted February 23, 2016 Trimmed the doors to fit the openings. The plastic hinges are being drilled for the hinge rod. A bit tricky to install the hinges to the doors and still get a perfect fit.... Link to post Share on other sites More sharing options...
M Graff Posted February 24, 2016 Author Share Posted February 24, 2016 I have mounted the hinges on half of the doors. It's great fun to get them to work properly. Link to post Share on other sites More sharing options...
M Graff Posted February 25, 2016 Author Share Posted February 25, 2016 Painted the doors on the roundhouse: Something is hiding within: Ahh, it's the old C19... Black and white version: Link to post Share on other sites More sharing options...
