I have always used tubular track or Super O.
I am redoing my layout and plan on using gargraves track. How do I bend the curves?
Bridgeport,check on the Classic Toy Trains forum for a good answer. There aren’t many ‘O’ gauge guys here.
As reklein said, the other forum will have quite a few folks who use Gargraves track. I only have one piece that is used on a display shelf. But it is quite stiff. I would use a plywood template to bend it against, just like I do for Micro-Engineering flex track in smaller scales.
I did read about somebody using a water heater as a form for their Gargraves track. But I go back to the idea of a plywood template on a flat surface to avoid introducing vertical irregularities as you bend the track. Also, be aware you will have to trim the inner (cut) 2 rails at every track joint to get them even.
my thoughts, your choices
