Router build

Jazz , I do agree ....
Do you feel I should just raise the bearing a bit to have a touch more clearance like Clive suggests ?

I don't find many examples of moving rails ... Got any links ;-)

A lot of people put the z rails on the plate that the spindle fixes to as it helps to stiffen the plate up. ..Clive

No I suggest you have moving rails.!! . . . .The whole idea with any area of the machine is to try and reduce vibration at the tool and moving the bearing higher will just make this worse. Yes you'll have more clearence but you'll get more vibration.

Most machine builds on this forum use moving rails so Check them out.!

To be honest if your just building a Router for cutting wood and soft materials then it's not a problem but if you want to cut harder materials which often require shorter tooling then it does become a problem. Moving rails helps get around this without messing around raising the work or having moving table.

If you want good combination so can cut all materials then have a moving table along with moving rails.

a little progress ....

i thought id try out using epoxy between two steel sheets and i gotta say it works great ! there is no ring from hitting the the beam , and its not 'that' heavy

wish i could have done some before and after tests ... but i dont have the time right now to play

did a quick test run of the X and Y axis today , its super smooth and so quiet, man you gotta love servo's !

Looking great! How did you manage to weld those plates with the oval holes inside the tubing

[Blackrat]

i cut the inner tubing into sections, then welded the oval plate piece and two rectangle sections together , repeat for the entire length

[EddyCurrent]

Did the inner tube have to be metal or was it part of the strength too ?

[Blackrat]

yea must be metal as this completes the sandwich ..
