Today’s Project

Posted by hammerscale on November 13, 2015

For today, a small project.

The guy on the right was missing his brother, almost identical twins except for a 1/4 by 20 tapped hole. I used 303 stainless, as I had a cutoff scrap laying around.

You’ll note a bit of Powermatic gold paint on the old piece, as this is a tube clamp for a model 95 scroll saw.

Atlas Drill Press

Posted by hammerscale on September 28, 2014

The most recent addition to the shop is this Atlas 15″ drill press, here seen as I received this fine machine, sporting no motor and safety yellow livery.

Here is it after new bearings, new paint, and some measure of love. The original Jacobs chuck was a little bell mouthed in the jaws, so I upgraded to a keyless Rohm chuck. I had an old motor from an Atlas lathe that suits very well, and replaced or made new hardware where needed. I may resurface the table in the future.

I think I’ll leave it set on a higher speed for woodworking. Right now I have three more drill press projects in the pipeline.

Carriage Lock

Posted by hammerscale on September 23, 2012

My Rockwell lathe comes from the factory with just a Allen head machine screw acting as the carriage lock.  What I’ve been using is a hex wrench sitting in the screw, which works pretty good, but falls short aesthetically and ergonomically.

So I finally got around to updating the arrangement by replacing the screw with a custom made shoulder bolt and lever.

Cross drilled and threaded to accept a 3/8’s ” rod. The screw is made of 41L40 alloy, which threads beautifully and is very wear resistant.

Machinist's Screws

Machinist's Screws

These old style machinist’s clamp screws are a step above socket head cap screws when it comes to style as well as substance.   The square head is a bit more accessible in tight quarters, and the integrated washer is certainly a bonus.   I’m always in need of machine screws of varying lengths for work holding on the mill table, and may make a few for the shop.  The furthest on the right is my first attempt, in 41L40 steel.   The knurling I added as a touch of ergonomics,  but the washer under the head should be much larger.   Back to the drawing board….
