Inexpensive DIY tachometer for a mill or lathe

It looks like Adam mounted the sensor in the spindle cap and is using putty to hold the magnet on the spindle. I would have done it a little differently. Here's an idea I haven't seen before. Adam made a very inexpensive tachometer for his variable speed X2 mini-mill using a cyclometer (bicycle speedometer). Almost any wired cyclometer will ...

Dial Indicator Helps Set Z-axis Height – MachinistBlog

It is particularly useful for adjusting the Z-axis height on my Harbor Freight mini-mill. I'm a little mistrustful about dialing in the height because of the huge amount of backlash in the Z-axis. So I often stick my DI on the column and use it to set the height or to double-check the dial and make certain I haven't miscounted the number of ...

How-to: Remove the intermediate gear from a mini-mill

This might be a good time to check and fix your spindle/column alignment. Mini-mills sometimes suffer from a misalignment of the spindle and column that can't be fixed by tramming the mill. Fixing it requires removing the head from the column, which you're going to have to do anyways to remove the intermediate gear.

Harbor Freight or Little Machine Shop Mini Mill?

I own a HF 44991 mini-mill and a LMS 3990 converted to CNC with Ron Ginger & Joe Katona at TechShopDetroit in 2015. The alignment of the HF head to the column is terrible. It's as if the person who assembled the HF just screwed the spindle housing to the column slide with no attempt to align it to the column.

An Easy Way to Reduce the Mini-Mill's Z-Axis Backlash

The typical Sieg X2 mini-mill [HF 44991, Grizzly G8689, Micro-Mark & others] has a lot of backlash in the Z-axis.In my case it was .053-inches, which was almost a full turn of the fine-adjust knob.
