RE: CN Blackwater division - cnrglen - 02-12-2024
I got the turntable backfor the second time. My friend added a pickup wiper to the one end:
Not quite as un-noticable as one might hope but it does the electrical pickup job. My friend made a video of it in action:
Glen’s Diamond Scale H.O. Turntable - YouTube
The test car on the turntable has a light in it that will stay on as the table rotates.

Looks great and is running smoothly.
RE: CN Blackwater division - cnrglen - 02-17-2024
Thanks Matt.
My friend came over today and we installed the turntable on the layout:
He held it under the layout while I drilled and screwed from the top a screw at each corner, going through the spacer blocks makes for a solid platform.After it was installed I checked my measurements and my 3/4" spacers did the trick. The bridge track will be level with any code 70/83 track that it connects with.
Now the next challenge is to fill the gap around the turntabe pit. There is about 5/8"gap that's 1/4" deep. I'm thinking of gluing cut down cork roadbed to fill, sanding to flush and then filling any other gaps with some wall filler. I'm trying to keep the fix as mess-free as possible so anything liquid is out.
Another item on the way is the control module for the turntable motor. I found a neat device on Abay and it should be here in the next couple weeks. (coming from China)
RE: CN Blackwater division - LiveSteamer - 02-17-2024
You're Welcome. Looking good and nice to see you got it installed. I may not have enough experience but I agree with you on how to fill it in. I'm sure they are other ways but that seems to be the easiest.
RE: CN Blackwater division - cnrglen - 02-18-2024
I'm not sure if it was the easiest but it's pretty close to how it was mounted in it's previous home.
I did get the gap filled today:
I ran the cork twice inside the gap on it's edge (I wasn't sure if it would flex around an 11" diameter witout breaking) and glued it in place.
Then I trimed it down flush with the layout and used some of the scraps to fill the larger gaps that were left.
When that had all dried, I used some spackle to fill in an spaces that the cork didn't. Don't worry about the pink, this stuff turns white when it's dry so you know when it's okay to sand.
RE: CN Blackwater division - LiveSteamer - 02-18-2024
Looks great. I see you went with the cork roadbed.
RE: CN Blackwater division - cnrglen - 02-24-2024
Thanks Matt.
I finished off fitting the turntable in
It took 3 fills and sandings to get the space around the turntable finished for painting. I brushed some tan paint on to blend all the sanded spackle in. I'm still waiting for the control module for the turntable and until I can turn to bridge I can't lay track and get a proper alignment. In the meantime, I'll continue to work on the enginehouse project.
RE: CN Blackwater division - LiveSteamer - 02-25-2024
You're Welcome. That looks great glen. Can't wait to see this area finished.
RE: CN Blackwater division - OBJack - 09-04-2024
Fantastic progress from scratch, in such a (relative) short time Glen, even hand-laying some track to boot.
And I am impressed with the simplicity of the brilliant little terminal block you made, genius. Will be interested to see more as you develop your layout.Jack
RE: CN Blackwater division - cnrglen - 09-05-2024
Thank you. I haven't been working on the layout for the past months because I've got the enginehouse under construction. When that is done I can continue to finish up the trackwork on the engine facility.
RE: CN Blackwater division - cnrglen - 01-05-2026
Now that the enginehouse is pretty much finished, I can focus on installing it on the layout. Before that I need to power the turntable so I can line up the tracks. I needed a controller that was small, easy to install and came with a reversing switch.
I found this DC motor controller on Ebay. It's a Pulse Width Modulated unit with a reversing switch included. It can be bought for about 20$ with shipping.
I made a mounting plate for it from a small piece of aluminum sheet.
Painted black and with the controller installed. The controller is input polarity specific, so it might take a couple tries before getting it right. I used a small 12 volt transformer to power it.
I cut a hole in the fascia and it slipped right in. I choose to place it inside the pit, close to the turntable/engine facility so you can eyeball lining up the tracks.
RE: CN Blackwater division - TMo - 01-06-2026
Well done, Glen! Can't wait to see the engine house in place.
RE: CN Blackwater division - cnrglen - 03-16-2026
Finally getting back to the layout.
I'm working on the turntable tracks and enginehouse install, starting with the lead-in track from the mainline to the turntable.
I hand-laid the lead track, starting by gluing in the wood ties.
Then I ballasted, sanded and then started to hand lay the code 83 rail. I did make a bit of a mess when I over-glued the ballast. I needed to use a dental pick to remove some of the glue that had gone over the ties and the sanding made it look really bad.
It's not the straightest length of track, but it sure has character. I did check my work with an NMRA guage and a set of high quality trucks and it all checked out. I'll probably airbrush in a bit of weathering to make it look a bit more 'industrial'
I did have a slight problem when I was finished tracklaying, the turntable track was a bit lower than the lead track so that had to be fixed.
I used some tongue depressors/ popsicle sticks as shims, painted them in burnt umber and glued them to the turntable structure under the track. The track had become unglued during this process anyway so It wasn't a big inconvience to fix this problem.
With the shims glued in I reattached the track using some acrylic latex caulk. It's a nice solid piece of trackwork now. I used some tape and a steel weight to hold it into place
When that dried I did a quick alignment check by moving the turntable back and forth and rolling the boxcar back and forth a few times.
The next step will be to figure out where exactly to place the enginehouse and then line the tracks up to it. I don't know if I'll be handlaying all those tracks as I'll need to make some tight curves for alignment from the turntable to the enginehouse.
RE: CN Blackwater division - TMo - 03-17-2026
Great work, Glen! I've never even contemplated hand-laying track, but you made it look easy. Can't wait to see the engine house addition.
