My single runner TS sled and a few tweaks

I like the idea of a single runner TS sled because they can be lighter and a more manageable size.

Mine has a few tweaks -
- a matching companion piece to support offcuts for cleaner cuts
- two fences
A - the front fence supports the material I'm cutting.
B - the rear fence does double-duty -
- push the sled without having to worry about distorting the front fence's alignment
- fine adjustment using the 1/4-20 bolt for on the left side

Youtube contributed lots of ideas. I combined the best from four woodworkers who generously shared their output.

Thank you to an anonymous YouTuber
- your use of two pieces of engineered flooring for the two-part single runner sled sparked this idea

Thank you to Nick Engler
- how to dimple HDPE strips for a precise fit in a TS mitre slots using a countersink and machine screws
- use a countersink to increase accuracy when installing threaded inserts for a no-fuss fit
- how to set up a 1/4-20 bolt as a fine adjuster rather than drill multiple holes in the bottom of the sled to fine tune the fence

Thank you to Patrick Sullivan
- your simple technique for seating threaded inserts nice and square sure saved me a lot of aggro

Thank you to Scott Walsh
- the simplest and most direct explanation of the 5-cut method I've ever seen that relied on just simple arithmetic
- kudos!
