I know most homemades have around 6" of draw, but I just measured a [k26] at full compression and it compresses about 8" is there a reason for this? (wouldn't you have to have an 8" draw to achieve full compression?)

Full compression rapidly degrades the power of the spring. You could make a blaster with 8" of draw, but you would ruin the spring after a war or two.

Ohh I get it, so even though full compression will have more power, it will damage the spring so 6" is just better
(am I understanding that right?)

Yup, and after a certain threshold, the strength needed to prime the blaster gets really REALLY hard.

Can I ask how you were compressing it? I've never heard of a [k26] being able to compress that far, at least not in a blaster under normal use.
I consider "full compression" as a fraction over seven inches of draw, although that extra inch of draw is relatively negligible as far as performance goes, unless you're a total range whore.
Yeah, go with six inches. Makes for a much more comfortable prime.

Going by the dimensions on the [k26], 11" of spring should have around 8.3" of compression. The power of math.
"In short, the same knowledge that underlies the ability to produce correct judgement is also the knowledge that underlies the ability to recognize correct judgement. To lack the former is to be deficient in the latter."

One of the primary reasons that 8.3" of draw isn't achievable is from spring shortening caused by repeated, complete compression. An 11" [k26] spring shortens to 10" or less after repeated compression. Designing a blaster with 6"-7" draw and slight spring pre-compression is a good way to ensure that your spring doesn't rattle due to said shortening, yet still maintains full spring decompression upon firing (and therefore, maximum efficiency).

One of the many symptoms of the spring getting fucked up.One of the primary reasons that 8.3" of draw isn't achievable is from spring shortening caused by repeated, complete compression. An 11" [k26] spring shortens to 10" or less after repeated compression.
