Why does my Grizzly G0824 vibrate so much?
- J
  Jennifer JohnsonAug 17, 2025
  Excessive vibration in your Grizzly Lathe can stem from several issues. It could be due to an unbalanced workpiece, which requires re-centering with the spindle bore. Alternatively, the workpiece might be hitting a stationary object, which requires immediate correction. Other potential causes include loose or damaged V-belts needing re-tensioning or replacement, misaligned V-belt pulleys, an unbalanced chuck or faceplate needing rebalancing, gears not aligned in the headstock, or worn/broken gears or bearings requiring replacement. It could also be the spindle bearings, which may need preload resetting or replacement.

How to fix a bad surface finish on my Grizzly G0824?

  Emily DawsonAug 20, 2025
  A poor surface finish on your Grizzly Lathe workpiece can be caused by several factors. Ensure you are using the correct spindle speed and feed rate. Check your tooling; dull or incorrect tools should be sharpened or replaced. If the workpiece is flexing, adjust the setup to provide proper support. Tighten any excessive play in the gibs. Prevent material buildup on the cutting tool by using coolant. Also, check if the bearing preload needs adjustment, or if the belts or spindle bearings are worn and need replacement.

What to do if my Grizzly G0824 carriage will not feed or is hard to move?
- J
  John HillAug 23, 2025
  If the carriage on your Grizzly Lathe is difficult to move, several factors could be the cause. First, ensure that all gears are engaged using the gear dials and that the half nut lever is disengaged. Check that the carriage lock is fully released and the screw on the feed handle is tightened. Clear away any chips that may have loaded up on the ways and lubricate the bedways. If the gibs are too tight, loosen them slightly. Finally, inspect the gears for breakage and the feed clutch for slipping; replace gears if broken, and increase clutch spring pressure if the clutch is slipping.
