Default looking for guide bushing baseplate for Bosch 1617EVS

Hi,
I have a Bosch 1617EVS with both a fixed and plunger base.

I have previously relied on roller bearing template bits when using template guides, but just bought a fixture that is designed for use with traditional style guide bushing inserts.

I have been reading about centering guide bushings with conical mandrels etc. and would like to make sure that the guide bushing I will use is precisely centered.

I want to use the Bosch plunger base with the fixture. Its base plate is designed with a crude quick release bushing system, and the plate does not seem to have a provision for subtle centering adjustments.

This seems like s good occasion to seek out and purchase a new base plate to dedicate for the use of the guide bushing.

I have found a listing for the Jasper Tools M 575B Router Base Plate Adapter, which says it fits the 1617 plunger base.

I writing to ask for recommendations for other base plates I might consider.

Thank you.

center the base plate using a centering cone...
remove the quick change and install the PC style..
see page 19~21 of your owners manual...

Hi,
Thank you for the suggestion. I purchased the router over 15 years ago and haven't referred to the manual since. I didn't realize there was an option to use pan head screws and alternate holes to make small adjustments for centering.

Thank you!

Nevertheless, I still think the Bosch plunger base's quick release system seems kludgy and crude, so I would enjoy finding a complete replacement base with a simple center hole, which the "Porter Cable" style guide bushings fit in.

The Jasper Tools M 575B Router Base Plate Adapter that I mentioned previously does not appear to have the sort of oversize mounting holes that would be suitable, so I am hoping maybe someone who shares the interest may have found another product that is ideal for the task.

Can you suggest such a base plate?

Thank you!

THis one might work.

Hi,
Thanks for the suggestions.

The first one is the one the one that seemed like a nice clean install, but as you noted the description specifically precludes the 1617 plunger base.

The second one is the example I found and mentioned in the original post. It is labeled to fit the Bosch 1617 Plunge base and does seem prepared for use with pan head screws.

The third one has a review that explains that it does not pre drilled holes that fit the Bosch Plunger

The fourth one has a vague description and the photos show all the mounting holes as countersunk and self centering, which negates the opportunity to fine tune the center.

Thank you!

Hey, Ben; welcome!
This video covers the whole Bosch bushing topic pretty thoroughly. The PC adapter is illustrated at 8:30 min in (more or less). No new base-plate required.
What Stick was explaining.

FWIW, I found another base plate described as fitting the Bosch 1617 Plunge Router Base RA1166 at Lee Valley:



I have ordered the Jasper M 575 and hope it will fit the need.

Thank you.

Just for the record I've used Bosch's guide set as described in the video and also acquired a PC style bushing set to use with the adapter. They work as intended so really no need to look elsewhere. Of course the proper base plate replacement can achieve the same just a different route but key is using the centering pin.

Thank you for the information.

I am very curious to learn if the expectations that I have formed through a couple decades of template routing with roller bearing bits will be matched by the use of the guide bearing system.
