Hey man I just came across your channel. I've been accumulating parts for an open builds machine. I'm just waiting for my spindle to arrive. I was going to make the plate-maker C Beam build, but I seen your upgrade videos. I believe that the mini-mill definitely has the advantage of being an easier-to-upgrade machine. I also got a 2.2kw spindle, and I've been really worried about it, since I want the horse-power. My intent was to use the machine to upgrade the machine, but it seems pretty difficult with that style of machine; not that this is easy, but you've very elegantly done a lot of the work of figuring out the process to add rigidity to this build.. I just wanted to say thanks. I've gone through your catalog. You make fantastic content. Cant wait to see what you do next.
Great looking part! I was curious as to the reason you drilled the holes on the drill press. Is it due to the spindle not having enough torque? Or more a convenience factor so you don't have to switch tools again on the CNC?
Yep, the spindle doesn't have much torque at the low RPM needed for good drilling feeds/speeds with HSS drills larger than about 1/8 diameter. If the holes are large enough (more than 1/4 diameter) I'll often do them on the CNC with an endmill and the "bore" toolpath to save time.
im amazed the results you're getting using an aluminum frame and leadcrews, i have the same spindle, or at least i believe is the same, 1.5kw 110v ER11 collet, what are the sizes of the cutters u use? since the collets included are mostly milimetric
Sounds like the same spindle. I used 1/4 inch two and three flute endmills, one is from lakeshore carbide and one is from yg-1, both from their aluminum-specific tool lines. I bought TECHNIKS super precision collets in fractional sizes to get lower runout, but that's not necessary if you got lucky and the ones that came with are low runout. You can use a collet that's up to 0.5mm oversized, so a 6.5mm collet is appropriate for a 1/4 inch tool, it'll close down on it.

@@imnoexpertbut Ok, makes sense. I'm evaluating a spindle like yours, or a lower RPM spindle with a belt driven motor. That's why I ask.
Another video! Great job :D Still improving my build whilst hovering your video's haha
That part looks nice. I'm still in shock at how well this thing works for how much it cost.

Great video, what spindle are you using on your mill?
looks like a 1.5kw, i have the same one
1.5kw 110v 3 phase er11 24k rpm. It says "Hua Jiang dian qi" on the name plate; I bought it on amazon.
