Reply to "1/4 straight tubular O gauge track?"

I need the short sections due to the peculiar nature of my portable modules. They are sized to accommodate a 4-car Lionel R-27 set but also to be able to negotiate the clearances from my attic down to my driveway.

I cut the sections with a razor saw starting from the underside almost all the way through, then finished cutting from the top of the rail with a Dremel and a cut-off disk.

Any tips for making those little crimps in the rail to hold the pins in place?

Thanks.
