Getting my Router up and running

[ger21]

Are you going to keep the 10 tpi screws?

Gerry,
Re. lead-screws, at this point I would say yes unless there is a really compelling reason to switch.

Is 2-3x more speed compelling enough?

[fuelsguy]

Well, if I can get 500-600 IPM out of my current lead-screws with the right motors I would say no.

You'll be lucky to get 1500 rpm, which would be 150ipm with 10 tpi screws. Most consider 1000 rpm very good for a stepper driven machine.

[fuelsguy]

Ah well, back to the drawing board to see what I can do.

thanks for all the help,
I'll let you know how I get on.

Also, consider that the screw may not be able to rotate that fast without whipping a lot. A lot of people find that screw whip is the limiting factor in the speed they can attain.

Gerry,
I think I'll stick with the 10TPI for now, just to get some experience with the machine and then I can upgrade to what makes sense at that time.
I did think about using a 2:1 gear set-up but I take your comment about whip. I have built an RC airplane using a long shaft drive to the propeller and shaft whip was a big issue in the design.
At this point I want to get a good reliable machine making sawdust and move up the learning curve a bit.

More to follow when I start cutting wood!
