I have the Benchdogs fence, rail dogs and rail square. I’ve found all three invaluable and between them I can deal with pretty much anything.
@petermillard may have mentioned some of this already but my observations are:
1) The width between fence and rail dog isn’t huge, maybe 600mm on my setup, but it’s fine for most cuts. If I need to make a wider cross cut then i
2) The rail square. This is a wonderful piece of kit that makes long rips and cross cuts wider than I can accommodate with the fence and rail dog setup easy. I didn’t think I’d use it much but I find I use it more and more over time.
3) I keep a track section permanently setup with the shorter bench dogs. I found that as mostly I’m working with 22mm or less the shorter dogs made removing the rail easier. Also the tip about keeping one dog loose is key. I keep the dog that sits behind the fence tightened (the one furthest away as you stand at the bench) and the other loose. It’s easy to tighten after the rail is down and then loosen to take off again.
I like this setup as it’s very portable. I keep a fixed bench in the workshop and an MDF sheet with MFT holes that I can Chuck over saw horses for work elsewhere. The fence can be easily moved between the two.
