wow, .05" (1.27mm) depth at 45ipm (1143mm/sec) that is aggressive! did you observe what is thr highest spindle current drawn?

You really need to be careful not to plunge your bit too fast or it will chew up your spindle bearings. They are expensive to replace. I found out the expensive way...

u might want to revise the feedrate a bit. It's 45 inches a minute, not 450 inches a minute.

And the plunge rate is 0.05@ not the cut depth.. I counted 14-16 runs to go through 1/4" of material. So it's not that aggresive at all...

My bad.
45in/min... = 19.05mm/second.
That is actually slower then what I did, 25mm/sec.
The difference is I use HSS end mill bits at 2000rpm. with ample of kerosene applied with a small brush.
& I hate cleaning up the steel chips...

Miguel,

Would you please give me some details on the compressor you are using with your cold air gun?

HP and tank size.

Thanks

the 3 minute video

Miguel,
Thank you for shearing. The 3 minute or so video has been a huge sorce of inspiration and motivation for me. I have had the plans for 10 years (when they were free lol) I have had them printed out on 11X17 paper for at least 2 so I am starting on the Y car soon (I have a quote for some of the laser cut parts) The balance of the "laser cut parts" I am going to cut on a friend's cnc plasma.

Thanks again
archie

Hey Archie, glad to see you posting about your build. I'm anxious to see how your "laser cut parts" experience goes.

I am more intrigued with the cutting and milling of the rails.
