lap microlathe

Today’s banner: the Taig MicroLathe. It’s adorable. It’s so small you can hold it in your lap. We’re completely serious:

How cute is that? You could pack it up in a box with some colored paper and take it to a crafting party!

We used it to make the very small collet featured in last week’s post, where we mentioned the need for a tiny slitting saw. Here’s how we did it:

The small silicon-carbide blade is mounted in a Dremel Rotary Tool, mounted to the Taig Lathe milling attachment using parts from a Vanda-Lay Industries Acra Mill Plus. Last week’s collet was parted from the piece of aluminum rod held in the lathe’s four-jawed chuck. Here’s the whole setup:

… One of the cats has made a guest appearance in our brand-new, absurdly-off-the-cuff photo studio. At night we can only see his eyes, which is kind of creepy. We can actually see him today, being as the backdrop is white…

a tiny collet

Hello,

Today’s banner: a tiny ER 8 collet. For the purpose of improving rigidity for milling operations with a lathe, we tried securing an endmill in a four-jaw lathe chuck:

We wanted to secure the endmill base using an ER 8 collet, but alas, the 3/8″ shank wouldn’t fit in any of our collets. ER 8 collets are absurdly small. But then, so is the Taig lathe. We like tiny things.

In principle we could make a new collet to hold the end of the endmill. Obviously we had to put principle to practice. We often do this, if for no other reason than to see what happens. But making collets is hard. Tiny collets require a tiny slitting saw. We persevered:

Here’s the endmill’s base in the new collet:

And here’s the chucked endmill, capped with the new collet (photographed from the rear of the chuck):

We had fun. To give a sense of size, or lack thereof, here’s the collet next to a thumb and a penny:
