Hi there,

Have ordered the jigs and am now somewhat patiently waiting for everything to arrive...

Only thing I'm wondering...I'm planning to build the turnouts and then mate them up to C83 Atlas Flextrack (I've got way too much trackage to think about hand-laying all of it!) and wondering if the QuickSticks tie-equipped turnouts will need to be shimmed up to match the height of the Atlas ties? My caliper says the ties are 2mm thick...

Hi,

Our QuickSticks for HO scale are cut from 2MM thick plywood, which works out to a scale 7" in HO, the same size as commercial trackwork ties. Our turnouts will match up precisely with Atlas flextrack ties, as well as all other HO scale trackwork.

Excellent to hear Tim!

Now, is there such a thing as 2mm thick PC Board? The trackage I'm laying is going to be going onto three separate pieces and I'd love to be able to use PC Board to solder the rails to so I can eliminate using fitter rails across the two dozen plus joints...

The only sizes of PC board available is 1/32" and 1/16", no metric sizes are produced.

When building a turnout on PC board ties this size mis-match poses no problem, as the PC board ties will "float" between the wood ties, and the resulting gap under the PC board tie will be hidden by the ballast.

No problems with that on the turnouts...Just hoping for a potential solution for the track ends and butt-joints of trackage. I know I could use brass screws and solder the rails to that, but very time consuming to ensure the screws are at exactly the right height, and potential long-term stability issues as well.

If you manage to find a supplier who can make 2mm thick PC board, I'm sure you've got a pretty good market for folks like myself...

Thanks!
Jon

All it would take is some .016" styrene shim under the 1/16" PC board tie, or .047" shim under the 1/32" PC board tie. Maybe some wood sheets could be found in these thicknesses.

Pretty odd thicknesses if you ask me...Mind, I could use 16pt cardstock under the 1/16" PC board, but then we're talking about three layers between the subroadbed and the rails...(shim, substrate, cladding) and of course, trying to ensure the adhesive works properly on all three is interesting in a lot of ways.

Those aren't odd sizes at all for styrene.

Okay, I'll grant you that. I obviously didn't think the odd thicknesses were made, and was proven wrong.

Have another idea for this...Get a small sheet of thin steel (the same thickness as the styrene you mentioned 0.016" thick) and then solder the PC Board ties to the steel, and then glue via some durable adhesive to the wood, and then solder the rails to the ties...

What would be considered a permanent adhesive for steel-wood connections that wouldn't pop open in the cold? Gorilla Glue?

... To what end, though?

Assuming that only one tie in six or ten is going to be PCB and thus thin, there will always be adjacent ties which will be full height. These full-height wooden (or plastic) ties will both carry the weight and serve to hold the track in place. If you're still worried (and I wouldn't be,) a dab of white glue applied around the PCB tie will creep into the gap between it and the roadbed and support it when dry. But really, my experience suggests that's much ado about nothing. The track won't deform, it'll be held in gauge, and the floating PCB tie won't be visible once ballast is down, so my take would be to fuss over the real (as in proven by testing) trouble spots along the right of way, whatever those end up being.

You're presuming I'm using those PC Board ties in the turnouts. I'm not, or at least, in the current portion of this discussion thread.

I'm doing nothing but modular layouts, and the current method of aligning trackage from one module section to another module section is to have fitter rails involved that span the gap between sections. While this works well for one or two tracks, some section joints have upwards of 7 tracks (14 rails) over the joint. Fitter Rails get really tiresome after 4, so I want to have some type of butt joint on the rails to eliminate the need for fitter rails, but want to make sure there's a really bullet proof way to ensure the rails don't move whatsoever, and also prevent them from being moved while they snag someone's sweater. The idea of soldering a bunch of ties to the rail appeals to me in that I can have a very solid connection from rail to roadbed.

And since the PC Board ties are thinner, need to find some way to bring them up to the common 2mm height.
