Options For High Speed Milling

[TomS]

So I'm curious how square it is, do you have to tram when you install it?

I haven't checked tram yet. Before I finish bored the mounting bracket bores I checked tram on my manual mill drill and bored both holes in one setup. It should be close but I will check it.

Nice job, I'm jealous, I actually got my router sitting out so I can make a mount. I have a Bosch colt, but you can only get 1/4" collets for it so whatever

These guys also, I bought a full set for my PC. http://elairecorp.com/routercollets.html

It looks like the Bosch Colt will only take a maximum of 8mm, you may have to get a bigger router if you want to go to 1/2 inch

Thanks for the tips, yeah I may want to go to half inch, I'm really loving my CGS Ferocious end mills and a 1/2 inch wants about 8-10k rpm for starts

Today I checked the mill spindle to table and I'm within .0005" in X and Y. No complaints there. Put the indicator in the router and tram is out .0085" in X and .0105" in Y. I was expecting it to be within a couple thou of the mill spindle so I'm not a happy camper at the moment.

I have to do some checking but my guess is the OD of the router housing is not in line with the spindle. It's a stack up assembly with the bearings in housings that mount on each end of the stator so there may be an accumulation of manufacturing tolerance. Whatever the cause I need to correct it. My plan is to remove the bolt on collar and overbore the router end of the mounting bracket about .030" for clearance. Then I can drill and tap the bolt on collar for set/jack screws adjacent to each of the four bolts and use those to tram the router.

Bummer, hope the solution works out for you.

It'll work out. I built this without any adjustment features with the thought that everything was square and true. The plan is to build in adjustability. I have a preliminary plan but need to think it through before I start modifying anything.

It for sure has me rethinking my plans for mounting up my Colt, I'd rather not have to tram my head just to use it

I agree with you. I don't want to tram in the router every time I use it either. So I'm going to overbore the mounting bracket on the router end. Then I can shim the bolt on collar to get the tram where I want it. No different than tramming the main column which we all do from time to time.

I was thinking I would just tram the head in both planes,(bridgy clone) but.... that's a lot of time with the tenth indicator, plus the offset of the router would be a pita to deal with tramming

Tramming the router is a one time task, unless I crash it. I'm willing to spend the time now and get it out of the way so when I need to do precise work I'm ready to go. It's just the nature of the beast so to speak.
