I have my doubts about all the wood in the construction, especially in the plunger shaft, i'm not sure it has the elasticity to withstand the abuse of a [k26] but I suppose time can only tell. The wooden catch ramp is pretty cool, I'm sure if the wood is hard enough it wouldn't have any durability problems...
...It's way simple yo, and more durable-Yay PVC!
As a note to all the wood-noobs, not all wood is created equal in terms of 'strength'; in terms of hardness (despite it being classified as "hardwood" or "softwood"), bending strength, rot-resistance, flammability, and most other characteristics. For example, this hardwood (commonly called "Ipe") has the same fire-resistance rating as concrete, and takes 3,684 pounds-force to dent with a .44 caliber ball (Janka Hardness test). Douglass fir, on the other hand, is what we in the US typically build houses out of and is highly flammable, has takes 660 pounds-force to do the same thing. The hardness does have an effect on the bending strength, but to get a better idea of 'strength' of any material, looking at something called a "Modulus of Elasticity " is much better.
Now, while I'm not going to explain Modulus of Elasticity (E) to you, I do have examples; like steel, which has an E of 29,000,000. Carbon fiber is something like 22,000,000; Aluminum is 10,000,000; Concrete (under compression- it does not take tension the same way as compression) is 4,350,000; Ipe is 3,140,000; Oak is 1,600,000 - Pine 1,300,000 (with wood it's important to orient the grain properly, those are the long way); Nylon, which I've seen used for rods, has an E of only around 400,000. Polycarbonate is similar. Other plastics vary, but hopefully you get the idea. And while woods need a certain orientation, plastics and metals need a vary specific temperature range - steel looses something like 50% of it's strength at around 800 degrees F, most plastics melt above 400, Wood does not (It does ignite, however, but will remain as strong as the cross-section of whatever hasn't ignited).
The long and short version: Woods vary tremendously by type- many woods are superior to plastics in terms of raw strength.

It's worth noting that if you use an Ace 62 spring on a 1/2" wooden dowel, you run the risk of getting tiny slivers of wood shaved off of the dowel as you prime it, resulting in splinters.
