Hi. I’ve read a few previous so if I missed any I apologize. I have 1f (journeyman rail on the way) My goal is to get something quieter than the makita. My plan is for mainly wood but may get into minor soft metals. I only see 80mm spindle mount available. What would everyone’s suggestion be? ---

They do make 65mm spindles, they just will not accept a 1/2" bit. My suggestion for most people is to go with a 65mm 1.5kW air cooled spindle. If you plan on building an enclosure for your table I think I would go with a water cooled spindle and then I would step up to 80mm because it’s been reported that the walls on the 65mm spindles can be very thin and are prone to water leaks. ---

I went 80mm to accommodate a 2.2KW so I can use 1/2 inch shank bits, and it is so nice and quiet and carves as deep as you can imagine and really fast speeds. I too am waiting on the X50 journeyman rails which I just got the shipping labels for. I’d do it again in a heatbeat. ---

Which spindle did you go with? ---

I’m still breaking in the machine, but so far I’m very happy with my cheap generic air-cooled 65mm spindle: > **[Mophorn CNC Spindle Motor 1.5KW 2HP Air Cooled Spindle Motor with Four Bearings...](https://www.amazon.com/Mophorn-Spindle-Engraving-Milling-Machine/dp/B07TNDLRHX?tag=benmyers-20)** > > Mophorn CNC Spindle Motor 1.5KW 2HP Air Cooled Spindle Motor with Four Bearings 220V ER11 Collet Air Cooling Spindle Motor 24000 RPM CNC Spindle 400 Hz for CNC Router Engraving Milling Grind Machine - - Amazon.com I’m driving it with a Teco L510 that I had sitting around from a [previous project](https://youtu.be/N9ns0_eRHuU). > **[VFD, 1hp, 115V, Single Phase Input, IP20, Medium D](https://www.wolfautomation.com/vfd-1hp-115v-single-phase-ip20-med-duty/)** > > VFD, 1hp, 115V, Single Phase Input, IP20, Medium Duty, 4.3 Amp, Speed Potentiometer, Easy to Program, Compact, 150% Overload, V/F Control, Auto-Torque Boost or Sensorless Vector, 3 Phase Output ---

I can’t find a 65mm mount though. Is the second item an inverter? ---

The 1F CNCs ship standard with 65mm mounts - the 80mm is an upgrade extra only. ---

The mount that comes with the machine and fits the default recommended Makita router is 65mm. If you go w/ a 65mm spindle, you don’t have to worry about swapping out the mount – just drop the spindle in. The second item is a Variable Frequency Drive, which is required for most spindles. Besides being quieter and being designed for longer running, most spindles also allow for precision speed control through the use of 3-phase AC. The VFD manages all of the voltage and frequency manipulation heavy lifting to make your spindle work the way you want it to. ---

Ok…gotcha. I will definitely go this way as the makita is headache loud. Of course the spindle you linked is “currently unavailable” lol. Ill keep looking…
