I found building my first layer of the helix is always the pain and time consuming with raising the screws a little, test, lower where required test lol. But once that first run is done successfully I cut a spacer and the rest of the layers went up quick as the spacer just set it Off from my bottom layer. Fun building one though hey :)

Threaded rod is a sensible choice. US practice seems stuck on using 1x2 "ladders." These are often made in batches with the level-to-level rise uniformly applied. The base legs are then trimmed to create the slope. US practice often uses "door skins" (sheets of either bidirectional or unidirectional plywood meant to face residential panel doors; available cheaply) to cut the entire 360º, which is threaded onto the ladders. Handy part with all that is having a central "man access" to the assembled helix. But, such things are simpler with the sort of manpower a club layout enjoys.

Another great video Charlie - thank you. It's looking good. A couple of things I learnt when I built my last layout which incorporated a similar Helix with threaded rods and nuts (albeit Swiss narrow gauge single track). I deliberately incorporated some super elevation (cant) into the track sub-bed (giving me 0.8mm across the 12mm gauge track) I started with the track level, and then worked my way around to get it adjusted correctly, time consuming but straightforward (Trains (no steam locos) run perfectly with a 380mm radius curve and a 4.5% grade) I also elongated the holes through which the rods pass to reduce the stress in the sub-bed because if you look at the vertical geometry the sub-bed is the long side (hypotenuse) of a right angle triangle. With only a 2% grade and a larger radius the difference is small but not insignificant and you may find that when complete the threaded rods are not be vertical, which of course isn't an issue if they are out of sight. Just my 2p worth but hopefully useful. Take care and keep safe john c

@@ChadwickModelRailway Sorry I forgot to mention that with my 4.5% grade I also had to use tapered wooden washers above and below the track sub-bed because when I tightened the nuts above and below they tried to flatten the sub-bed. With a 2% grade this will not be so noticeable but don't over tighten them because the clamping effect will be to flatten the sub-bed.

Hi Charlie. Wow that'll look pretty impressive once it's finished. When I was involved with the old model railway at Sheffield Park on the Bluebell Railway which had a model of Horsted Keynes station it had a 2 turn helix at one end that was built in. There were fiddle yards top and bottom of the helix as well as a single lead junction and facing crossover so it was pretty involved in the days before DCC. I think it went up about a foot so one end was a helix and the other was a single arc that dropped down quite steeply. I do remember my old mainline Jubilee used to struggle up that so it had to be restricted to three coaches anti clockwise. Great fun to operate but it was very temperamental. I do believe it still exists but it's stored in one of the many containers around Horsted Keynes.

DCC Concepts certainly has some interesting products. The Powerbase is something new to me and a great idea. The helix kit is a nice pre-designed alternative to big sheets of plywood & a pile of saw blades. But I have a love-hate relationship with the idea of helices. On one hand, they're an elegant solution, especially for most of us w/o 2000 sq ft of space for a RR. But I hate the "waste" of so much expensive track where it isn't part of the scenic railway (not to mention the cost of materials). If only they could double as fiddle yards & storage areas. Elevators are now another viable solution, but have moving parts (higher maintenance), require operations, and aren't cheap either. Alas. What I want is the improbable. A continuously graded multilevel circuit that rises & falls while circumventing the room(s), BUT without requiring lift-gates or duck unders. In other words, the holy grail. 😁

Hi. very impressive and informative. You mentioned about the track being level. In real life, tracks are at an angle in curves to compensate the centripetal force of the train and helps also to keep the train not slowing down. In my curves, the first 30cm of curve track is not glued to the track bed, but then for all of the curve length ( except the last 30cm ), i elevate the outer track just 1 to 2 mm from the inner one. It works really fine.

Hi Charlie..... All looks to be coming together just fine. All the research.parameters etc spot on and explained well. Something worth considering when finished is to make up a control train.... loco plus a load of rolling stock that can just make it up the helix without wheel slip. Keep this train as a unit train or take note of it's makeup, throttle setting etc maybe also. First run: Track must be 'virgin' ... clean as possible and shinny. (Track could be washed in your sink maybe as you assemble helix's. [G} ). Reason I pass this on is as you use the up helix performance will change depending on how you clean the track or run your trains. The control train gives you a base to compare performance against later on. You may get a few surprises depending on how you treat your track.

Nice video. Great to see such a full treatment. When watching the spreadsheet work at 9:00 as you cranked up the revolutions to cover the 18 inches to get the grade down, I became worried as you were not watching the elevation gain per revolution. It’s all nice on paper but in that One revolution you have to get the loco and cars in there by height so the roof doesn’t hit the bottom of the next revolution. 3.27 inches is what you computer. That’s going to be a very tight squeeze for OO locos. Not running electrics the pantograph issue doesn’t come into play. But you still will want the space to be such that you can get your hand in there to address an issue if needed between the levels. So my recommendation to folks is to build it to the lowest height that will work for your locos (tallest loco with pantos up if your need that) and still allow your fingers over the loco so you can pick it up and place it back. That sets the minimum gap per revolution. The room then likely sets the radius of the circle, of the grip of the loco with what it is pulling and the all of that determines how.far up you will go. The elevation gain is really a function of the per turn gain needed to reach in and the radius that you can work with.

I think what your comment has highlighted, it’s just the complexity of the whole installation. I do realise there is little clearance within the levels, in fact there is only half an inch between the top of the train and the next bed, but I believe that’s enough. Regards Charlie

G'Day Charlie. Mate this is so you don't sound like a naff ok, its pronounced In-Ox, not I-nox. :D Oh and welcome to how I have to sometimes secure the track to the roadbed in my Loft (40°+ at times), only way to keep the track down and at the same time allow enough room for expansion in the track (when its really close to my Steel colour bond roof). Although I'm still trialling extra long broadhead pins and I don't hammer them all the way down, leave a little bit of wiggle room between the head and the sleeper (will find out if its going to work soon, summers a coming). When I can secure the track down more permanently, I think may have told you this one before, I use Sika 300g Black Sikaseal Appliance Silicone Sealant. If I do need to remove the silicone due to say, an error or track layout change, I use Selleys 375g Silicone Remover. The best bit about using the above, is it sticks to everything, and I mean everything (that includes me). :D www.bunnings.com.au/sika-300g-black-sikaseal-appliance-silicone-sealant_p1210606 www.bunnings.com.au/selleys-375g-silicone-remover_p1232412 As to your helix, mate its almost a work of art! Although I would have thought that gluing on the mounting plates to at least one leading edge of each section of radius arc before fitting might have made getting the next section glued in easier when its all put together. Also are you going to put a little bit of super elevation on that, its sort of screaming for it as in certain camera angles it looks like it has an Anti-super elevation (may well be just an optical illusion). And I agree with the other guys who have commented on making the center hollow for ease of maintenance and recovery/rescue. You will thank your self later (although it might be best to send the grand-kids in/under that low bench work). :D Looking forward to seeing how you get on, take care matey and keep on having fun (no seriously its meant to be fun) LOL

Great Teamwork Gents ! Well that was a really informative video and and on a personal note, the timing of it is brilliant for me having recently got my own helix from James. Great minds think alike Charlie, because I’m also going to use PowerBase from DCC Concepts on the outside loop. I’ve also planned for a third inner loop which will be 009 gauge and reversible so will also have PowerBase. However, there the similarities between our plans end. I’m going to use DCC Concepts track underlay and, as the radius of my loops is greater than third and fourth radius, will be using flexi track (wish me luck !). Thanks James for the tip about the start of the helix rise by creating that flap in the baseboard - a very neat solution ! I was wondering how to achieve a smooth transition from baseboard to helix, now I know ! And good to learn from your lesson about Copydex Charlie, I also use it to stick track down, so may rethink that strategy where the PowerBase will be. And looks like a visit to B&Q (other DIY stores are available 🤣) to buy some more clamps ! Thanks again Gents for your joint production, you really do combine to produce an easy to understand step by step guide and your efforts are much appreciated. Take care.

I first thought you could more easily use plastic or steel sleeves on the rod, but then realised the need to make the structure rigid. And well done on not poking your eyes out on any of those rods....or is the next video from casualty😂? Should you run out of curved rails, I'm sure I have a lot spare! As always, an excellent video with lots of valuable information.

Wow, that is a lot of hard work, but it should be worth it to have a great running helix system. I did notice James forgot to add the 2nd rod lower (12:12) washer for tightening the rod to the first curve, hopeful that is sorted post production. I also noticed that you didn't use a say Peco track to track spacing/distance measure in the build so that the track remained equally apart? Great video and clearly explained by you both. Thanks again my friend and I will look forward to seeing it working on your layout. Once you work out how to get it home, lol.

Don’t worry John that washer was fitted. I did occasionally use the Peco six-foot way-gauge, but the main thing to keep the tracks the right distance was just to align the track edges at each timber joint. That way everything was aligned perfectly throughout.

1) Instead of nuts and washers between each level. Pieces of tubing cut to length. Either to a stop on a chop saw or a lathe. Washer above and below so the tube does not cut the plywood. 2) When laying out the curves with a beam compass instead of the track centerline mark the outside or inside (a)of the crossties on the flex track. Also make up stop gages that have the same radii as the outer or inner edges of the cross ties. Temporarily screw the gages in place. Glue down the flex track with the cross ties against the gages. You could even make the gage pieces permanent to act as a protection against derailments getting to the edge of the helix. a) Assuming a two track helix. Personally l think the threaded rod idea is a bad one. A small diameter threaded rod such as 1/4 or 6mm is too flimsy. As is full circle helix sections. To cut the correct curvatures on the inner and outside radii of the helix sections a radius cutting jig for a band saw is the way to go.

@@ChadwickModelRailway One thing about the nut and washer arrangement. It can pull the helix section level when tightened. If using the old spacer block method the blocks between helix sections should be cut at the slope angle of the helix imo. The risers at the bottom should have the blocks cut square on the bottom and the helix angle on the top of the block. Another method for risers could be vertical sections with dados cut at uniform spacing. With the dados cut at the helix angle. The helixes I've worked on were for material handling and vibratory ones for assembly machines. On a model railroad any helix should have an access port in the center. Just in case. One thing about helixes. While they are big space wasters in a lot of ways there are other uses that they might be able to be used for. Curved turnouts on the outside track that lead out through a tunnel for a mountain railroading scene. Think narrow gage in the Colorado Rockies.

Hi Charlie! Been following you for a long time, and like many of your followers I've been struggling for many weeks with the "to build or not to build a helix" conundrum so your timing here is perfect! Fascinating explanation of the maths and other issues so I'm waiting impatiently for the next episode. But what intrigues me most is your comment that it's the track that's the most expensive element of this project. Track certainly isn't cheap but surely the helixes themselves cost more? So much fine detail work and materials involved. Maybe they cut you a special deal? ;) Anyway, keep up the great work. Cheers, Peter

A small problem with the maths! A rise of 5.5 turns in 18" gives 3.25" (83 mm ) rise per circle. The radius 3 curves are then on a 1 in 36 gradient, very much steeper than the 2% suggested. Clearance may still be a problem as at the sector joints there will be two thicknesses of plywood plus the underlay; a total of at least 15 mm and maybe rather more. Added to this is the 4.5 mm height of the code 100 rail and the resulting clearance over rail head is less than 60 mm. No problem for normal running, but it makes accident recovery difficult. My helix has just 59 mm clearance and I know the problems. A further word about DCC Concepts Powerbase. PVA sticks this without problems provided that you keep to the instructions and weight the system down adequately while it sets. I used house bricks laid in pairs with only small gaps between them and let them set for at least 24 hours. Remember that laying any curved track on a gradient involves twisting the track which makes fixing it more difficult. My track was fixed with the spiral collapsed to a simple stack so that there was as little twist as possible at that stage. I only expanded it after it was assembled and stuck. On reflexion, I think that screwing it down as in the video might be preferable. Finally, remeber that the incoming and outgoing tracks have to continue rising until after the outside edge of the track has been cleared. This adds a further foot or so of gradient to each end of a helix.

Interesting points Graham. I did show on the spreadsheet that the inside track was much steeper hence it being the down line. I also mentioned that the Powerbase needs to continue until the train exits the helix, not just the loco. How is the reliability on yours and is loco grip an issue? Regards Charlie
@grahamthompson6622
3 жыл бұрын
@@ChadwickModelRailway Yes, loco grip is a problem. My layout consists basically (much oversimplified) of a single track folded eight mainline 40' long rising by 1' (at a fairly constant 1 in 40) followed by a 4-track helix - radius 2, 3, 4 and a notional radius 5 track at 25" radius - to rejoin the two ends of the mainline. The two inner downhill helix tracks have slopes of 1 in 36 and 1 in 42 respectively while the outer pair are at 1 in 48 and 1 in 54. The whole of the mainline and the outer two (uphill) tracks are fitted with the DCC Concepts Powerbase. In practice, anything that will travel up the mainline will work conmfortably on the helix. None of my diesel locos requires magnets neither do the dmus, my Bachmann 9f and any tender drive locos all with a maximum trailing load of 7 coaches. Almost all other steam locos require magnets with some needing three even when mounting them only betwee 0.5 and 1 mm above the railhead level. Painting the edges of the magnets black reders them unnoticeable although some of the brake gear has had to be removed to make space. This too is unnoticeable in normal operation. The magnets give no trouble when away from the Powerbase lines even when passing over Kadee magnets.
