The Big Helix: Shaping The Roadbed and Laying Cork (340)
HTML-код
- Опубликовано: 13 июл 2024
- Today I'll continue with work on the bridge between the helix and the rest of the layout. In this case I'll plane the pink foam roadbed down to create a shallow transition to the bridge, then lay the cork roadbed over that. Afterwards I'll plane the cork with my Surform tool to create another smooth transition from the bridge onto the cork. Once all the dust if cleaned up it'll be ready for laying the track!

Nice to see you working on the layout again, I enjoy all of your videos but I especially enjoy working on the layout
Your knowledge, talent & excellent teaching skills combine to make watching this video a pleasure at the same time as I’m learning . These directions are perfect timing as I need to make a transition on to a spur off of a 3 mile long siding near my tire manufacturing plant that used to use rail to a greater extent or at least without spending money to upgrade their short spur even though NS is continuing to replace ties further down the siding. Thanks for continuing to make great & informative videos 👍🏽👍🏽👍🏽🚂
Thanks Larry, great 'how to Video, Keep safe.
Thanks Larry.
Nice progress Larry looking forward to seeing it completed.
Dear Larry, your comment on using the sure form tool on the foam is indeed accurate! Got the same experience here. In that sense the sure form tool is more appropriate for shaping foam into rough forms, or to create a rough surface to better adhere any kind of material to the foam. To make such elevation changes in an XPS foam I prefer to use my Metabo micro planer. To achieve true smooth grades and transitions I cut the ditches first, which I then use to place temporary aluminum 5x20mm 90° angled profiles on both sides of the track alignment. After that I run the micro planer with its back-end stabilized over the two profiles. Although the micro planer produces a lot of XPS debris, the smoothing is a real breeze, especially because the micro planer’s speed can be adjusted to the appropriate speed for the XPS foam. Even though foam manufacturers prescribe speeds for power tools, it pays off to do some trial runs on a piece of off-cut. By the way, I also experimented this method with my router. Works just as fine. Although the ease of the micro planer is in its elongated sole, which truly helps to make a smooth cut every time. Must add there that it is imperative to not become over indulged. It pays off to be patient and smoothen the XPS in small increments. Cheerio
Once I cut through the outer layer the surface isn’t all that rough, especially the cork. The rough stiff was mainly along the edges of the ditch wall.
Have to admit that I was puzzled last time why the bridge section didn't come to the height of foam, but now I understand!
By the way, did you know that Stanley make a Surform twice the length of the one you're using. That would have made even lighter work of the "carving." One of the favourite tools in my toolbox, as it does away with more sins than a Catholic priest.
For the transitions from cork to plywood I cut tapers on my table saw, 3/16 to zero over 18”.
Cedar shims, available at most big box stores work for this as well, just make sure you buy the LONG shims, not the six inch shims that come in shim packs.
Great idea.
Loved the video, had me wanting to get back into the basement
hello larry it's is randy and i like yours video is cool thanks larry friends randy
Something that you didn't mention is that you need too remove the Vapor barrier on the 1/2 and 3/4 inch foam, it will make it easier to cut.
The stuff I get doesn’t have the plastic vapor barrier, does the rest still come with it?
@@TheDCCGuy , some of it does. Depends where you buy it.
Love your work. How is your wife doing?
Still wearing a cast, but getting there.
Off topic question? The back drop building on the top shelf of the layout. Are they kits or prints?
Those are prints of photos of actual buildings in Lynchburg, VA. I used contact adhesive to attach them to the backdrop and also to black foam (Gator board) sheets and attached those to the backdrop giving them a 3D effect as they stand off the backdrop. Unfortunately the company that made them is no longer in business but there are a lot of others offering similar products.
@@TheDCCGuy thanks for the update. Not only that thank you for t he great weekly videos you produce. Very great full to have found your channel
