This is a follow up to my earlier post in which I griped that my new Bosch 1617 router did not have a flat base. After reading nothing but glowing reports here and elswhere about this router, I decided to quit whining and flatten the base. I took the motor unit out (no brainer), removed the sub-base, and lapped the base with a coarse DMT diamond stone (great stone, BTW). The protruding bosses that were causing the problem were no match for the stone, and I had the base flat in 5 minutes. Put the sub-base on, inserted the motor with a 2-in stright bit, and checked for quare. Dead on. Problem solved. Thanks again to everyone. Nick

Happy to hear that, Nick. Enjoy the new router.

Nick,
I took the plastic base off my router and found the metal base to be milled flat. No raised bosses. I didn't measure it with a gauge, but it's as flat as I can discern using my machinist's square on it and eyeballing. That's good enough for me.
Put the plastic base back on, and there's a trifling out of flat area on one side. Less so than I described in my response to your other post. There must have been something under the plastic.
I'll take the plastic base down to flatness tomorrow.

My situation turned out to be some sawdust I had not wiped off when I returned router to the phenolic base it mounts on on my table. It was between the router base and the phenolic plate when I re-attached the screws. Ha..
Looks like alls well that ends well.....

Curious; What did you use to check the squarness of the base to the collet/router body? Just a long straight bit or did you use something like a piece of 1/2" bar stock that you knew was true?
The reason I asked is, I've never paid much attention to tuning tools until I got involved with woodworking to a little higher level. I'd like to check my router table setup to see how true the axis of the router is to the table.

A 12" piece of 1/2" drill rod should work just fine. A machine tool supply should have some. I would be afraid of plain old cold roll.
I use a centering mandrel and a gage block to see if the router will cut square to the base. I rotate the spindle by hand and check for daylight. No daylight--I'm happy! If I had seen daylight, I might have used a dial indicator to measure runout at the base and then 2 inches from the base. BTW, it's interesting to compare the depth of the hole you cut with the distance the bit extends beyond the base. Nick
Thanks for the tip. I have the 1.75 hp 1617. Great tool, but I had noticed (but ignored) that the base deflected a bit when only 1/4 of it was on the stock. With your comment I removed the subbase, and the holes into which the sub-base is mounted had a 1/4" or so ring of protuding metal (1/64th or so, I guess, didn't try to measure).
Put a piece of 100 grit PSA on my jointer table, and ground them to flat. No deflection now. Thanks a barrel!
