HELP. New>>>need correct sub base and template guides for Bosch Colt

G'day Barry, and welcome to the forum.

There are many base plates available from Amazon and other sources.


There are also many videos on YouTube showing how to make your own base plate.(also a few posts on this forum)

THank you James, I appreciate the help. I have some acrylic perhaps I could fasion a base plate. Would say 1/4 hardwood work okay? Any reason I should not make a base out of wood?

I suppose you could, but I would use acrylic.

I feel that 1/4" hardwood 4x4 piece may not be stable enough.

Ages ago I made a round base for mine. Their screws aren't equally spaced front to back, so the job was a little harder than I expected.

Use your existing plate to make a copy. You just need to size the center hole to fit the bushings. The hardest part might be centering the hole. On previous plates that I've made, I attached the plate and carefully lowered a running bit though it. You're unlikely to find a router bit that's the correct size for the bushings though. I've used Forstner bits on a drill press in the past.

I dunno if it's any help but here's the drawing I made to make my round base. You may need to adjust the size of the center hole. The outer circle should be 5-1/4" if printed to scale.

I have the Wood River guide bushing set and like them. Here is a link: WoodRiver - Router Bushing Set with Case - Brass - 10 Piece. I often use 1/4" template stock and they work nicely with this thickness; with the Porter Cable set, the barrel is too long to work with 1/4" template stock. You need to make sure the guide bushing is concentric with the router bit otherwise you get undesirable results.

This sub base should work. You can always get the centering cone, made by many suppliers to make centering easier,

Here's a kit. I love using my Colt for hinge mortises. Replaced all interior doors in my house. Former owner had dogs, and I also cut an opening, covered with a grille, to allow evaporative cooler air in with door closed. https://www.amazon.com/Hinge-Mortising-Kit/s?k=Hinge+Mortising+Kit
