Hello Randy. I have been looking at the news on TV. I know you are active as a volunteer firefighter. I just want to make sure you and your family are safe from all the devastation. My prayers are with all those affected by the fires in California.
Bill from Seattle
All good here. Our nearby fires are no threat and about out. It is the other parts of the state now. Thank you for your concern.
Randy Richard In The Shop Good I'm glad you are safe
Nice upgrade. I thought at the start that hole for the wire was going to be a real pain in the butt, but slotting it was a nice work around. Well done, Peter
Yeah after some more thought things change for the better. Came out great and works great.
I have that same Tachometer on order from China . Been over a month now ! I sure love this idea on the mounting .. THUMBS UP!!
They work great. Well worth it.
Nice build addition to the new power setup!
Thanks Chuck.
NICE job Randy - an inspired solution. I still keep using my cheepo hand-held electronic deal but your idea there is just great. Super.
Well worth the time Chris, they work great.
Love the old time 'Chicken Head' knob on the control panel... kinda reminds one of Simpson meters. :)
That is an old Baklite knob, good eye's.
They're (for real) called 'chicken head' knobs... and still made in all sizes/colors, and maybe even in Bakelite. Check eBay and and all the usual electronics parts outfits... I heard a while back they're now the rage on rock band amps.
Nice. I am planning to do the same with my woodlathe. Good to see how it can be done.
well worth it, they work great, I have them on 3 lathes.
I like it, I will have to look into fitting one of my antique lathe.
They work great Steven. Nice to know when you want to repeat cutting the same material.
Very nicely done, Randy. Always good to know just where you have things set when you want to reproduce a process again.
Hope all is going well!

Thanks Tom. Things are good here. I hope your new house and shop are coming along, alot to do before winter.
Very well done as usual. Thanks for the video.
Thanks Harold.
randy looking good.
Thank you Bob.
Randy checking on you guys lots of fire around your area. Stay safe my friend. Ed White from Georgia
Thank you Bubba, All good here.
Nice upgrade
Thank you James.
Randy, do an ebay search for a KSD9700 Temperature Controlled Switch order a normally-open one, say for 35 or 40 deg C and place it in series with you aux fan. For extra security parallel two in case one dies. Only about $1.27 with free shipping. Now your fan will only run when it needs to.
Craig
I have thinking about doing that, I have three spots I could use them. That way I could buy in bulk. Thanks Craig.
Wow, an older lathe going High-Tech... ;)
Looks good...
For you in the US metric is a weird thread whatever the pitch is, it starts being weird when it's called metric... lol
That's right. Weirdtric that is the common term. They could not even get the conversion factor right, 254,, 234 would of been easier to remember.
Easy to remember. 1" is EXACTLY 25.4mm, Works for me... ;)
The only negative point here is that the lead screw on my lathe is Imperial and I have to leave the carriage engaged when threading.,..
Got to practice and get used to translate instantly in your mind, takes a little time, though...
Wish we'd gone metric eons ago; far superior; with the exception of the Celsius degree being a little big.
rwbishop Imperial is better for most things except a case could be made for wood working and mechanics but machinists prefer imperial.
Very nice work Randy.
Thanks you Mike.
Hi Randy.. Those meters can be setup with multiple magnets. The more you have the better resolution you will have in regards to your tacho reading.. Maybe a thought to ponder...
I will a have to get a few thin magnet and see how much better. So far these have been +/- 5 rpm.
That's a great addition for the lathe.
Thanks Ken.
great looking rig RR.
Thanks Greg.
Very nice Randy, enjoyed!
ATB, Robin
Thanks Robin.
Hey Randy, is that some of your blood splashed on the left QCGB at 4:57 ??? LOL Great job and video. The Tach is nice to have, I would like one for mine.
Probably, I seem to always have a small wound. These are very cheap on ebay, well worth it. I have one all all my lathes.
cool Randy!b nicely done
Thanks Phil.
Nice work as always...
Thank you RC.
Nice Job Randy.
Steve
Thanks you Steve.
nicely done!
Thank you.
Love it.
Thanks John.
Just got my tach kit in the mail today. :)
What are you using to power your tach?
I use old wall worts. Old chargers for devices. I used a 9 VDC output one in this project.
Thank you. I'll follow suit on mine.
Was any calibration required - if so how was it done. Enjoyed the video.
No calibration. I have checked them and all of the ones I have used have been +/- 5 rpm or better, close enough for what I do.
Nice installation for the Clausing. What did you used for the 9 - 12 VDC power supply for the tachometer electronics? I like the Hall Effect tachometer for ease of installation provided I remember check for the correct magnetic N-S orientation before gluing in place. By the way, a M12X1 thread is the one used on my old Unimat SL1000 lathe spindle and bought this size tap years ago for making parts for the lathe.
I used a 9 volt dc wall wart, I mounted it in the control panel for the lathe. The thread was a bit of a pain, but worked thru it. I really like knowing the spindle speed on a lathe, great ref. for the next project. Thanks Paul.
Thanks for the info. I used your Hall Effect tach installation instructions I saw from one of your 2014 www.homemadetools.net articles and installed the same type on 2 of my lathes and published the setups at the same website.
Does the JB weld hold that magnet on pretty good?
I am looking at doing the same thing on my car.
Has not come off yet, been there a few years now. Thanks
@@RRINTHESHOP cool! I love watching machining! Good video!
14:12 how come it still displayed 400rpm when it wasn't turning?
bcbloc02 on mine there is occasionally a lag
I think it has something to do with the "clear zero time" which is claimed to be 10 seconds on the product page. www.ebay.com/itm/4-Digital-Red-LED-Tachometer-RPM-Speed-Meter-Hall-Proximity-Switch-Sensor-NPN/251369593713?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D46673%26meid%3Df34a9d1d2324455c911b5af05ab0017d%26pid%3D100033%26rk%3D3%26rkt%3D8%26mehot%3Dpp%26sd%3D301487348110&_trksid=p2045573.c100033.m2042
I will clear after a few seconds when stopping. I think they have a slight delay on some small amount of averaging to smooth out the reading, so when the spindle stops it takes a few cycle of the chip program to clear.
Smart solution. Where did you get the mag-tach item?
Jim, ebay. just search hall effect tachometers, you can get red or blue displays. Just maters if you are color blind I guess. i like the Blue.
Great series. Curious as to why you run your cut off tool upside down.
For one it lets the chips fall out easier so they don't jam.
Throws the chips downward
Yes, why?
Cutting forces push the tool away from the stock rather than deeper into it. Good for lighter weight machines.
Well now for the real reason, not to say all very good comments. It is a left hand tool, this way I can get very close to the chuck when parting which is always best. This tool is a seco tool and works very well, I love it.
What power supply did you use? I think I'm going to use batteries.
Just an old DC 9 volt wall wart. I think any DC 6 to 15 volts will work.
Thank you sir.
Kinda sounds like a worn-out harvester lol what is rattling so bad
Yep, I think I found a lot of the problem the other day, in a video soon. Thanks Chris.
Randy Richard In The Shop can't wait
She's a bit noisy eh? Last time I heard a sound like that I discovered a hole in the side of an engine.
