I answered your IM but in case you missed it:-Raudi1 wrote:... I see "vintage 1/24" made an awesome bullring oval w/ the Keid method... What switching method did you use? Hoping to save a ton of time in trial and error... I'm willing to learn.
The Demel Cuttoff saw, with the 1/4" MDF glued to it base (which is the material I was using for building the track anyhow), makes a cut that is about 1 mm deep - which is the thickness of the wire. You can tweak this by affixing thin pieces of tape to the "foot" to finely adjust the depth of the cut to match exactly where you want that wire to be - but suffice it to say - very little material is removed.
It is very easy to "freehand" and you can also remove a rectangular recessed area for the lane change plates just by moving it around -
There is so little material excavated, and the MDF material is pretty soft - so the cutoff saw can easily clear or mill a small recess, and because of the 1/4" MDF "foot", it is guaranteed to not go any deeper than that 1mm depth- no matter where you cut.
When you do this yourself you will see just how shallow the 1 mm "slot" is - not at all like the woodworking a typical routed wood slot car track requires.
So yes - I used the lane change plates as per the manufacturer's instructions - and filled the "milled" or "routed" recess with a small amount of spackle or plaster.
Here is link to another discussion on a dedicated slot car board that might be interesting as well:
