I haven't tried the
Dave Ronyak Adapter, but it looks like a great solution. However, I do see two disadvantages to that; the added length of hose means you probably need to adjust the cord
accordingly, and the additional weight and bulk of additional fittings so close to the tool may not be as nice as just a single hose. If you go this route, I'd suggest purchasing the adapter from one of the dealers here that make them up, rather than shortening your D27 hose.
My opinion is that all but the sanders could benefit from the larger hose, but a few of the other tools require the adapter due to their dust ports -- however, you can also get a tool-end fitting for the D36 that will fits those smaller ports,
Here is one thread that discusses this but I cannot seem to find the other thread right now... Keep in mind too that the smaller hose is a little more flexible, thus handles a little better in use that the larger hose, so the smaller hose is better for sanding than using the larger hose with an adapter. Anyway, I don't mind hanging the two hoses from my Boom Arm, and it allows me to use the larger hose for those tools that produce more waste and the smaller hose for sanding. If you take my prior advice and install the D27 in the Boom Arm's brackets, then you could simply attach the large D36 hose as described with the rubber bands -- easy on, easy off -- as needed if you prefer.
If this post doesn't read as good as it could, it is because of the late hour and way past my bedtime... [scared]
