Going to put that on your ham radio rig I take it?
It’ll go somewhere. Wall, desk, antenna. Who knows, I just wanted to cut something quick lol

Very Nice…
Just got through using a 4-flute with 2.25" stick out in steel. MR-1 didn’t care, but their was vibration and chatter that shorter stick out should reduce.
Ya that is a lot of stick out- I try to keep it as short as possible or run greatly reduced cut parameters.

Only using, because I have dozens of longer endmills. All my shorty’s are 2-flute and mostly HSS.
Make sense- strongly recommend investing in some, variable flute/ variable pitch end mills for steel. Helps eliminate chatter. For deeper cuts consider looking into some reach end mills or reduced shank end mills.
Typically for deeper stuff, I will decrease depth of cut and increase width of cut.

Looks good! I’m going to buy some of the jacks from SMW. Looks like you can use plugs and pins for end stops as well.
Modified some toyota spindles tonight to allow a different axle shaft to work in them which requires taking about 0.040" of it. Ran the bore probing cycle which made setup super quick and easy. Barely squezzes in the z axis range but if it fits it ships. We also swapped our coolant over to Qualichem xtreme 250, much less of a residue left, no staining on aluminum and the surface finishes appear to be better.

Awesome project for MR-1! Thanks for sharing.
I need to actually update my thread. But I jumped the gun slightly before resin because I needed to get a part done so I could get other projects done while waiting for the resin to cure. Easy toolpath and something that a manual mill would have been more than happy doing, but I jumped into the medium end of the pool first with a steel part of unknown hardness. Had some decent looking uncoated 4 flute carbides that were obtained when the wife’s work was throwing a bunch of stuff out, so I threw one of those in because I don’t want to use anything too nice until I get a bit more handle on things.
T-nut for a quick change tool post on my small lathe. Cut great and surface finish was nice. Cut it dry since coolant and enclosure aren’t hooked up yet. Machine seems to be living up to its hype. Steel was my main concern and I was very happy to see that it seemed more than willing to chomp through it

Well I’m finally able to join the party. Started the build around Thanksgiving, made my first part yesterday… lol TRS Robotics: First Official Part on the MR-1 (not sure if the link will give a preview)…

most cities have a hazmat drop off free of charge. theres plenty here in california. But i thought that coolant was like super eco friendly? Maybe it can go down drain.

Nice work! Did you thread mill the acme thread? Oops, sorry. This was supposed to reply to the post showing the gear puller. Couldn’t figure out how to delete this post!
No the threaded parts are too be welded in.
But, I have done acme threads on the mill before. This thing is wonderful. Big time money maker.

Finally. First part off the mill. Not without ripping stock out of the SMW vise first though. Oh well, live and learn.

Took my SMW vises out of my machine and put them in the bottom of my tool box.
After ruining a couple hundred dollars of materials for that same reason.
Put the Langmuir low profile vises in and have not had a problem since.
Tried it all. Well you need to watch the video…
You need to use a torque wrench… I wasted $1000 on two vises with all the accessories. Anything that is 1" or higher than the vise will come out under a load. Its just a matter of time. I’m sure they have there place but, I have no intention of sending anymore parts at the windows of the machine.
