I'm considering using Brusso's template for their smaller hinges, but I'm mystified as to the router bit, and bushing. I've exchanged several emails with their tech support and I'm still mystified. Their template calls for a 3/4" OD "bushing". A bearing would work, but in that configuration such a thing doesn't exist. Here's my last email exchange with Brusso. Has anyone used these templates, and if so how was the bit/bushing combination achieved? I may just fit the hinges manually with chisels like I always have.
Me: what's confusing me with your template description is the requirement for a 1/4" straight router bit WITH a 3/4" OD bushing. I know of no off-the-shelf router bit with that configuration; it's the 3/4" bushing that's baffling.
Brusso: Our best advice for this would be to simply cut and/or grind the router bushing to a shorter length. We are not aware of an off the shelf router bushing that is short enough to work with our templates.
