I cannot understand why Festool seems unable, or unwilling, to come up with an extension SYSTEM geared towards trimmers to accompany the Kapex. Heck, even a little guy in Minn. came closer to what's required with the sawhelper....
Here's what I think we need, based on my own experience, and what I've seen guys improvise in the field:
Easy mobility and quick set-up. ( existing Kapex extensions probably fill this need)
Full-length, solid material support. One or two material standards will not support short or odd sized cut-offs, allowing them to drop to the floor. (seems to be covered by the new extensions)
Full-length (or at least extended) back fences for proper support when cutting crown or other trim.
Full-length (or at least extended) crown stops for cutting in the nested position. The stops must be easy to install and remove ( or even better, just slide or flip out of the way without losing their stop location) for convenient switching from nested cutting to flat stock cutting. The stops should also allow for lateral movement to provide for a zero clearance adjustment to the blade.
Adjustable support legs to account for uneven floors or ground.
The legs need to be robust and solid to endure bumps and allow for for the stress of coping, sanding, even minor planing, without coming out of alignment.
Just a few thoughts, I'm sure we'll have more.
