Silver and Deming Drill Index
Steve the Locksmith asked if I could take some pics of my home-made Silver and Deming (S&D) drill index. S&D used to mean drills made by Silver and Deming, but now it's come to mean any 1/2" shank twist drill bit. The 1/2" shank allowed use in a Blacksmith's post drill, now it allows the use in the ubiquitous 1/2" Jacobs chuck.
You can buy a Huot drill stand for S&D drill bits
, but $40.00 is a lot to spend on organization and Steve is as cheap as I am.
My drill index. No, I don't have a complete set by 64ths of the S&D drills. I pick them up used and resharpen them. Sets can range from a cheap import set by 1/16ths
to an insanely expensive US made set by 64ths
.
The top surface is a sheet of self stick label paper. I printed up the layout for the holes with teh sizes beneath plus a number of unlabelled holes. I then used a sheet of laminating sheet over it.
I stacked all three pieces together and drilled the holes using the printed locations as a reference. I made the holes slightly over size. And yes, I really need to clean the grime off. It has stayed surprisingly readable over the years.
The panels are held apart by aluminum spacers I made on the lathe. 4 long flat head machine screws hold it all together. The panels are made out of scrap plastic, probably ABS, that I had laying around.
The countersunk flat head screw.
It's a good idea to keep the sides open so all the chips and such can fall out.

Making Wheels From a Scotch-Brite Pad
A friend wanted to know where to buy Dremel 511E EZ Lock Finishing Abrasive Buffs cheaply. Looking around it seemed as though they were a bit over priced (about $1.50 a wheel). I haven't examined them up close but they seem to be a standard non-woven abrasive made into a wheel.
I use Scotch-Brite pads in my shop all the time.
They're available in a variety of grit sizes and the price is about $1.00 a 6"x9" sheet. On Amazon they are $20.00 for a box of 20, Scotch-Brite 6-by-9-Inch Hand Pad, 20-Pads
. They are available all over the internet and from most industrial suppliers.
Mandrels are ubiquitous as my drawer shows. You can get mandrels with a screw for about two bucks as well.
So I traced a circle on a pad.
Wow, high tech.
I cut it out with scissors and mounted it on a mandrel. The mandrel screw can just be poked through the center. A washer in the center would make it work slightly better, be more aggressive on the edge. You could even stack a few together.
I also tried using an arch punch. This would dull the punches over time...
This is a finer abrasive.
Some test scratch patterns on silver. They seem to work fine. I'm not sure if they hold up worse than the Dremel branded ones, however from a 6"x9" sheet you can make about 54 (assuming you're perfect) 1" wheels so you can imagine the cost savings if they even last 1/10th as long.

Some Machining Content
Just a few machine pics:
Turning the OD of a magneto pole shoe.
Pressed onto a mandrel and driven by a lathe dog.
Kent made this holder for his tap wrenches.
And tap handles, these are made from Panduit scrap.

A Nice Walk to the Covered Bridge
We went to the annual Library Book Sale on Saturday at the County Fairgrounds, afterwards the weather was nice so we crossed 53rd St. and went for a walk through the OSU research farm.
This is pretty much in the city of Corvallis. Not bad.
A long asphalt road that goes all the way to the campus downtown.
Looking north.
There's a covered bridge!
Max was a little slow.
Turnbuckles tension.
The dramatic rapids...
Trusses.
An exciting plaque.
That's the muddy creek, those rapids above were an illusion.

Babies and Nature
Just some pics of what we've been doing lately.
Max making a bird feeder out of a pinecone, peanut butter and birdseed.
Max and Henry enjoying a teeter-totter.
Henry en route to a duck molestation charge.
Adoring our friend Bev's baby.
Henry was nervous holding the baby.

Energy Efficient
We received a card saying that we could receive free testing and sealing of our heating ducts. A quick check with the power company confirmed it and we made an appointment.
A nice guy (also working on his Masters degree at OSU) showed up and got to work. He sealed off the front and hooked up fans and gages.
I felt a pang of sympathy as I hate going into the "attic". The guy found multiple problems and was working until about 7:30 at night. End result was our duct air leakage going from 250 CFM to around 50 CFM. That should save us money.
We also bought a new front loader clothes washer. The old one was on its last legs.
The new drain hose was smaller in diameter than the old one which left space for air to get into the house.
I took two pieces of plywood, butted the edges and drilled a hole at the edges.
Some weatherstripping and we'll paint it in the summer.
Now for other pics.
Henry with one of his latest Lego creations.
He put a small flashlight inside the vehicle.
So it lights up the dark.
Max is a bit obsessed with those Big Mouth Billy Bass talking fish. So we made a paper frame for his head. That's his impression of a talking fish.
It kept him in place for toothbrush time.
Here's Kent working on something at shop night.
Drilling the end of a long piece of flat stock.
