Harbor Freight Caliper as DRO

(1/1)

rockknocker:
I just ran across this project on HackaDay and wanted to share it with this group.

This fellow used an inexpensive digital calipers from Harbor Freight as a DRO for his small lathe. The calipers were modified to allow for mounting and brackets were fabricated to mount them.

I've never seen this before and thought it was pretty smart.

What makes it even better is that HF had these calipers on offer for less than $10 recently when I visited

Try http://www.amtools.com who used to be 800watt on ebay.  The site was, as of a minute ago or so offline for updating.  I have placed several orders with them that were all honored and delivered promptly.  The small DRO I use on my lathe tailstock ran about USD12 with shipping a couple of years ago.

Jonny:
Scales are calipers without the internal/external measuring but they don't do them in decent lengths at affordable prices.
Have used Aldi verniers £5 to repair X and Y scales electronics, just a straight swap when they pack up.

Bought a load of verniers some years back from Chester when they used to have sales prices £1 boxed, some were over 3ft long in wooden box(well over £120 each). 2 out of 3 worked. Used to use them before I had a proper dros on the mills.

I have modified a digital calliper to act as a carriage dro, see:

Although the calliper is only 150 mm it can be moved to almost any position on the lathe axis so length is seldom a limitation
