Is it my turn? Anything to do with lathes, mills and other shop tools

A new tool. I've been taking a break from the bike, so made this little power file. Motor spins way too slow, but it works really well.


Hi toglhot,
you could increase the sanding belt's speed by swapping in a larger diameter drive wheel or by using a variable frequency motor controller?
 
toglhot, very interesting. Something I have been meaning to try for years. Did you boil the anodized metal after the electrolysis? Does scratching with a piece of steel show a hard surface? I like the ability of the process to give different colours by incorporating dye. A commonly used dye brand is Dylon which is available in Australia.
 
Another garage sale refugee for the shop....

...decent lil Atlas drill press. Needs some TLC but for $50 couldn't pass it up.
 
toglhot,
Your right about the toxic qualities of some of these plating solutions. Rather than burning up my anode to make a concentrated plating solution, I opted to get the specific sulfate. I got some sodium Dichromate to dip the newly plated zinc parts in and it's probably the most dangerous of the lot. Spooky stuff! Still waiting on items before I can get started. Have a chemical mask and will work outside.
I saw a tube where a guy was supposed to be electro polishing. He was using a lead anode. I think his "polish" was a lead flash. If so, it won't take long to tarnish. Also brighteners like for nickel, are expensive. They say it guns up your solutions and your better off not using any. Don't know but I would think this also includes Sugar, or Karo which they sat is Dextrose. The Karo I got was Fructose and won't work. Bummer.
Good luck. I'll be following your progress.

Saw this on Ewe Toob, so it must be true...:laughing:

Take a microwave transformer, remove the secondary windings and replace it with a couple of loops of heavy welding cable. The result is low voltage (mine puts out a shade under 3VAC) but high current. I don't have a way to measure it, but the one on YouTube was in the mid-50 amp range.

Plugged it into the footswitch operated outlet on my Milwaukee portaband stand. Worked well on some 26 gauge galvanized sheet. I can see that being handy if I want to roll some collars or something.

Worked okay on some 16 gauge stainless after I buffed up the contact points. Took a little longer, but certainly doable.

Now that I have proof of concept, I'll refine it a little.

1. Better electrode arms to keep the electrodes in alignment.
2. A handle to allow me to put some pressure on the joint.
3. I'm using brass electrodes as that's what I had on hand. Not sure if copper would be an improvement or not. Input appreciated on that point.
 
came across this today.

Hi WideAWAKE,
I was at an awkward age when I got laid off my machine design job, ( too old to easily find work, too young to retire )
I did an interview at a local machine shop
Got your machinist papers? Yeah, from Rolls-Royce but it was 40 years ago. Show me how you'd center and face this shaft in that lathe.
Think I couldn't work a 4-jaw chuck did they? Five minutes later; Can you start tomorrow?
But my very first job at that place? Design and build a drip-feed coolant mount. Mine was better, it had a magnetic base.
FWIW, if you ever need a magnet, every speaker has an effin' big magnet in it.

Mid you see to the end of the video, the guy does a redesign. Includes a magnetic base.

I grew up in the machine shop. Ran a manual grind shop for about 6 years. First question we asked people who interviewed was if they could read a vernier caliper and a mic. Then measure a few things and tell us the measurements.

Weeded out A LOT of people. Ohh that and the pee test.

it was heartbreaking to tell a guy we couldn’t hire him because he was gonna have to go on maternity leave soon… cause he was pregnant! :doh:

Hi WideAWAKE,
When I joined Atomic Energy of Canada in 1970 there was a full medical (to find any existing conditions so one couldn't blame it on the radiation)
and they racked me with questions:-
Do you have a drinking problem? No, it just slips down. We'll put that as a "no".
Lucky for me that the Doc and I were both Brits and shared a sense of humor.
 
I needed to cut a slot of a precise thickness with a radiused end to mount the orifice plate in the metering valve for the flow bench I am making.

After a bit of YouTubing I have used my boring head as an adjustable fly cutter. I works quite well but I can only take small cuts, that is not a real problem as I only have to have to cut a 3mm deep slot and I am not trying to make money.
The slots clean up if I take a spring pass the light grey on the far side of the slot is plastic swarf that has heat fused to the cut slot.

Got a new (to me) air compressor. A coworker moved into a house that already had a compressor so he sold me his old one for $250. Its a 6HP 60gallon, 14.5cfm at 90psi Puma. I cleaned it up and serviced it. Added an extension to the pump oil drain so I could change the oil easier.
