Looks great. Very clean.

Thanks. Looks like that paint was discontinued in January 2023 so finding some sort of chemical that could accelerate the curing process is likely not going be available. Nothing else will get painted until everything is ready to be painted. Then just leave everything for the requisite 10 days or so and do something else. Like go on vacation...
Wouldn't be a decent forum if we didn't also post failures as opposed to successes.
I thought I had it clamped well enough. Probably did. But without flood coolant the feed was too high for the 4 flute bit and slotting. Did fine on the two edges and then I had to hit E-Stop. Picture is worth 1000 words.

Ouch! That hurt!
Does it still smell in there? Or did it all stay in your underwear?
I was so careful. Clamped and blocks underneath.
Probe the hole several times after homing.
Edited the G-Code to not start spindle and changed travel clearance.
Set Z=0 to 2" above and did a dry run to make sure i had clearance.
Enabled spindle and reset Z to top of casting.
As it was doing the back side and the WD-40 vapourized I thought "Maybe I should slow the feed a bit".
Well 25 ipm was too fast. The air jet wasn't on enough. Slotting with a 4 flute in cast junk aluminum not a great idea.
Melted metal stuck in the flutes.
Now at the mall having a burger while I ponder what to do next.
Did you empty the mall out? I would not want to sit next to you.
A&W is only accessed by old folks so there's lots left...

I put a feed speed pot on my control board, and I use it a lot. Probably the most used control of all.
Agreed four flute mill and aluminum not a great combination. It always seems okay until it's not.
Alright. Status report time.
Making progress with the two flute 3/8" end mill and 5 IPM still at 2500RPM spindle speed. Air on harder and I could actually use the shop vac to suck up many of the chips. Nice too, how the table covers fit since this piece was smaller than the vise base.
Now why am I doing this? After about 3 tries at a 3D print cover for this lower half I realized the real problem was that the casting was just a tad too wide and when moved down to tighten the belt made things even worse. So a narrower and shorter motor mount makes the original cover suddenly fit perfectly. Here's the completed one only a little worse for wear from the mistake.
But wait you might ask. If I'm using CNC to mill this X axis motor mount how am I driving the X axis and how did I know the covers will now fit properly?
Easy Peasy. Just make a temporary motor mount.

And no... I did not poop my pants although the medication for the gout that showed up a couple of days ago certainly makes me want to...
Is that enough information 😛
Just one more cover to design and print up.
Done! Before I paint all of them I think I want to 3D print a wrench holder that I've mocked up with wire. Especially since the paint takes so long to cure.
The plate holding the draw bar wrenches would cover the "FORCE International" label but then with House of Tools no longer around who really cares.
And that's a better place for the wrenches instead of all over the place. I have two others used for the hold downs and the vise bolts but they don't get a lot of use unless I'm using them...

Hmmmmm...... Something really strange about that......
I realize you are just yanking my chain but what I meant was that if I'm not moving the vice around or using T-Slot based clamps to hold work then the two wrenches just sit on a table beside the mill. Always in the way.
OTOH, until I finish the new rendition of the power draw bar the two wrenches hung up on wire there are used all the time.
And my wife says I'm strange. Have you been talking to her?
Nope, no way! That would go against the unwritten honour code here.
Ya, just yanking your chain. It made me laugh so I thought I'd try to share the fun.

no problems... just challenges
So, I haven't read all 31 pages...but seeing the CNC work...and the 3D printing along with it...to achieve goals...
If no one else has heard of him...I'd like to suggest a quick watch (and I mean that as his longest video so far is still under 50 mins)
NotAnEngineer on YT...he's an Aussie...with a well thought out mind, a clever wit...and get this...a scratch built but definitely never truly done working on CNC mill...
I believe his trade is more of fabricobbler maker of things, as his 9-5 is at a props making shop.
I laughed at every video...because he is not shy about sharing his mistakes...I can't say anything he does is educational...but what it is...is a clear message...do not fear projects out of your scope of skills...

A friend told this about the picture of my mill with the completed belt covers:
So I thought I'd oblige him and send him another photo more in keeping with that concept.
