Easy Bending of Gargraves Flex Track with 2 Sided Jigs

tplee ·
I use two sided jigs that I have made to make my track curves as smooth and consistent as possible.The jigs are made from 1/2" MDF.  Each jig has two radii for each curve radius that I will need. Those radii are 72", 80", 88", 96", 104", 112",...

Gargraves flex track help

dangerwildmike ·
has anyone created a template for this?  Like 036 042 054 etc.  I think I'm going to try to design my layout around 054 for the curves and was wondering how to make a template for easier bending or if there is an easier way.

Does anybody know if the flex track can be bent to 038? It's for a dummy siding with a sharp curve. Thanks joe

Gargraves 37" Phantom Stainless flex track Plastic or Wood Ties

Now that I have decided on Gargraves Flex. I plan on bending all my own curves on plywood templates. My question is, based on ease of working with the track am I better off with the wood ties or the plastic ties. I,m thinking that the difference in realize-um between the two in minimal so which is easier to work with? Thanks Jerry

Like many others on this topic within the forum, I've been following it for several years but this is my first post. Over the past year, I've been iterating on a potential layout plan to occupy our basement utility/furnace room (which measures 17' x 19'). I've attached the most recent track plan as developed in Railmodeller Pro. On this version, I haven't included any of the intended buildings and I realize its without some key dimensions, but regardless I'd welcome feedback on the scheme. A...

Hi Joe, You can pretty much bend it to what you want. Just make sure you make a jig for what you want and go slow and easy. It takes time, as I had to do a lot of it on my old layout.

It can be, it takes time an patience. We use jigs cut to a slightly smaller radius.

You can bend that stuff as tight as you want, but as everyone advised above take your time and work it gently and slowly.

Here is a picture of the jig we used to bend Dual Gauge track down to an O-80. We cut a jig and then attached that to another piece of plywood. 3-4 ties were removed from each end. Next, the track was bent from about 6" inched from the end of the track slowly bending and working the ties. When installed we will have lines drawn to follow and will work from one end to the other.

Scott, Not familiar w this software but think I know what i'm looking at (scale wise). Looks nice. I like the large curves - esp for the larger O scale stuff that requires 042's and 054's and the upper track plan. I'm 12-16 mo away from starting a build. Trying to maximize space is part of the fun - I think. I'm leaning Ross as well but still debating controller location, type. I love their 3 and 4 ways'. Enjoy the build and have fun, Tom

Hi Scott, Visually, the blue line loop is going to hide a lot of the yellow underneath. Does Railmodeller have 3D objects so that you can see that? Hidden switches will be the ones with derailments from finicky cars. Ideally, having the loop on a mountain and the yellow line running outside the mountain (steep, cliff sides) would solve that, but, it looks like there isn't space for some O90 on the bottom yellow. I know the space is limiting the design. You will find the yellow line on the...

If I'm reading your plan correctly, you're gaining 7" of vertical height on the left side, through about 151" of track length, including a lot of curves. That's a 4.6% grade, almost as steep as the Lionel #110 Trestle set. With rubber-tired locos and speed control you can get away with murder. But personally I wouldn't be comfortable with anything steeper than 2.5%. Since it's not advisable to build a yard on graded track, I would scrap the gold/yellow 3-track yard on the diagonal part of...

I'm with DK on this one. I knew I would be using Gargraves track and Ross turnouts when I started my layout. I gave Steve at Ross my hand drawn trackplan and layout measurements. He converted it to a scaled out plan and identified all the different radii of track needed with the exception of the "custom curves". He also identified all the turnouts and prepared an full items list and put the package together for me to purchase and pick-up. Fabrication of the "custom" curve trackage was kept...

FWIW, Here are some screen shots of an older thread discussing flex track jigs. You might find the dimensions for the curve radius on the jigs useful, and the photos of the actual jigs to bend the track.

Re: Gargraves flex track help

Gilly@N&W ·
I concur that if you can get sectional curves, that's the easiest way to go. If you want an odd diameter, make a jig and go for it. I find it very useful when I'm "here" and need to get "there". For random pieces, I just bend it on my gut. For a sweeping curve, two screws to anchor it on one end. Then work your way down the length and add screws to hold it as needed. Doesn't look like this part has been mentioned. AFTER you bend it, you'll want to cut the ends square again.

I just made a couple of scaled down jigs based upon your idea. I had a kink in my track where the end of a piece of track ended up a couple of inches into the curve. Had not been a problem until I got my new Legacy GP30. Derailed every time it went through the curve. I unscrewed the track and removed the ballast near the joint. Used the jigs (one on each side of the track) and a clamp. Smoothed the offending kink right out. Installed new screws and replaced the ballast. The whole operation...

if this method works for you, fine, but i've got to take exception to the word "easy" in your title. when i lay Gargraves track i only have one bending jig and that is usually the handiest cylindrical object that's about 20-30% smaller than the curve i'm attempting to create (often a wastebasket). Gargraves track has an interesting property when its being flexed. try to create a curve from a straight without a radius to bend it around and you're going to get kinks. but if you bend a piece of...

To the OP: Congrats....and job well done! Very, very impressive. However, I still feel the terms "easy" and "Gargraves flex track" are mutually exclusive. I tried it once in the mid-80s, failed miserably, and vowed never to do it again. Fortunately, when I got back into the hobby in 2002 or so, Gargraves and Ross had started to sell fixed curves. I was off and running. When I was younger, I watched two buddies build their modest layouts using HO Flex Track. They could literally mark out...

Gargraves is easier to work with than Atlas flex track. I did not build Jigs for my radii. I drew out the radii I needed, with a transition at the beginning and at the ends. I tend to over bend the gargrave flex to an Atlas 081 section radius piece then expand it to 0100 or 096. Nice work, enjoyed the pics.

Buz, thanks for a great thread. I did have a question though once you bend the track into the curve and you screw it down is the radius pretty much set? I'm wanting to do this on an upper level that's only wide enough for the track per se, and wanted to be able to bend it down below to the correct radius and then relocate up above. Can this be done with your method? Thanks, Joe Gozzo

Re: Easy Bending of Gargraves Flex Track with 2 Sided Jigs

A slightly different approach. We used a large compass, and kept the center rail in-line with the compass point, (ball point pen), as we continued to screw the track down every 3 to 4 inches. Atlas track screws were used. The initial pen lines were used to install cork roadbed. Center point all curves. Ball point pen on top of the center rail as screws are being installed. You are also adjusting all ties as you work at fastening the piece of flex track. Rail Ends are squared with a dremel...

split cork roadbed (split down the center at a 45 ° angle) will bend quite naturally when laid down to follow the track centerline. i use a few nails to tack it down as the track will eventually firmly secure it to the substrate.

Buzz, Great work both on the Jigs and pulling together such a nice post. May I add one more jig suggestion to your collection. A curve easement jig. Instead of abruptly transitioning from straight to full curvature, ease on into the curve! Start with a 10 inches of straight, then make a continuously changing curve that starts at something like a 0-200 (100 in radius) and smoothly transitions to O-72. You can decide how rapid the change in curvature is. My guess is going from O-200 to O-72...

BILLP, makes a great point about easements. The beauty of using flex track is to make your curves look less symetrical. Make the track go where you want it to go. Not where the compass tells it to. If you want your curves to look perfect. You may as well just buy sectional track. On an operation note. I run body mounted Kadee's. Even on passenger cars. On curves with an easement. No derailments even if the curve turns into an 072. Without them. Instant derailment coming off a straight...

using wider radius track to modify the entrance and exit from a curve is ok, but don't forget the complete term... it is called a " spiral easement", the point being to start with an infinite curve (straight track) and gradually ease into the full curve, not just widen the entrance with a less severe abrupt change.
