Machining the DIY Repeat-O-Meter Base! WW153

[@stonecraft745]

I was taught to ream with much flood coolant, to keep the ream from expanding due to the heat and getting oversized holes. Also low rpm to keep the ream cool and much higher feedrate than at drilling. I hope you will read this. Great Videos! Greetings from Germany!

[@adamonline45]

I really like how you show the fusion settings window over the cut it's making! Very efficient way to share the info, and in a way that's familiar and easy to process, no wasted thought cycles to understand the cut! I'm sure that was a lot of hard work, but it really paid off, for me at least :) Thanks, as always!

[@piccilos]

love this style of video, that you can see the "action" along with the settings and troubleshooting tips.

[@ROBRENZ]

Nice John, waiting to see it complete! ATB, Robin

[@D4vecolem4n]

Excited to see how it turns out!! 👍👍👍

[@Dakakeisalie]

It's big enough that I can read the feeds and speeds! Thanks (on mobile, don't have time to sit at computer to watch these)

[@KenToonz]

Nice closeup photography. Didn't Tom talk you out of using the bandsaw?

[@bcbloc02]

Guess it is time to adapt to running the mouse left handed. :-)At 9:40 it looks like the part and vise are moving around is that the focus on the camera or what did you have the camera mounted on?

[@themikebray]

Excellent video!

[@GeofDumas]

I've always had bad luck with shoulder bolts. i've had to make my own with McMaster precision ground round stock Good luck with the tendinitis. Stretch your legs while you're waiting for the machines to do their thing. Sounds unrelated but everything's connected. It made all the difference for me

[@asblittle]

Hope the tendonitis gets better soon - when I worked in a design office doing CAD all day I taught myself to also use the mouse left handed. I was never quite as fast as right handed but it meant that I could switch back and forth throughout the day as one wrist became sore. You may want to give this a go and see how you get on

[@AndrewPrice2704]

Tendonitis: try mousing left handed. I learned some years ago, now I am ambimoustrous. It was surprisingly quick -- just a few days and now I can easily swap if one arm or shoulder is sore. :)

[@DSCKy]

Get a track ball or touch pad, etc and switch back and forth between them and a mouse. I got a little tendonitis from using a track ball for a couple of years and switched back to a mouse for a while to cure it. Uses just enough different muscles.

[@r.j.sworkshop7883]

I did mechanical design for 8 hours a day for 10 years. By the end of the first year I took the time to learn to mouse left handed and I would switch hands each month. A few minutes to re-configure my desk on the 1st, and it gave me an excuse to clean my desk a bit. Now both hands are equally worn out. Good Luck.

[@mwechtal]

NYC CNC You might also look into a Roller Mouse. It was fast for me to learn, and is usable with either hand. My Occupational Therapist recommended it. They're available on Amazon.

[@DSCKy]

I worked IT for 28 years. Many of our users were left handed and when I worked on their computers, I learned to work a left handed mouse. Was interesting at times. :)

[@ammo83981]

How do you organize your tools on fusion? Could you do a video about your tool setup please??

[@danl.4743]

Woot! 67th! I don't know why I need this, but I want to do this as a project for learning and experience. :)

[@elidouek5438]

Whats the deal with the radial arm drill at 0:24? If memory serves me well, last time we saw it, it was covered in citri strip and crap. From the glance we saw it's looking a lot better

[@raulirimias4810]

Hi John. Have you considered to use a trackball mouse? Once used to it,you will adopt it. It will ease your computer work. Good video by the way. Thank you for sharing your knowledge with the rest of the world.

[@fightersmurf]

hi john, look into a logitech trackball, the good thing about those is, they are fixed on your surface and you only move your fingers to move the ball, you can plant your wrist fully on the table. the model is logitech m570 wireless trackball.

[@Sketch1994]

My experience says that it's just the unsupported edge of the part hanging out of the vice. A lathe chuck can support a length that's 4 times the diameter of the part without a tailstock because it mechanically supports it against (assume stationary chuck) both up and down and side to side. My rule of thumb is that on a vice when you get close to 1 times the clamping width of stickout you are limiting the rigidity of the workholding because a vice mechanically prevents the part only from moving side to side and maybe downward (if you keep the parallels to the setup). The only thing supporting it upwards though (unless you clamp from top to the parallel) is friction with the jaws by the clamping force.....but you don't want to crush the part with your mighty vice!

[@webosm6494]

Listen to the doctor before it gets worse! Best remedy, start using the mouse with your left hand, took me a few hours. After that it is just as easy and fast to use. Also learning more keyboard shortcuts really helps. My current favorite shift+F10 instead of the right mouseclick.

[@tobarapprentice6618]

John, I know that this is an older video, so I hope that this question gets to you. What metal did you use. I want to make one, have figured out a number of the dimensions by measuring screen shots but nowhere does anyone say what metal is used. I am concerned that with a .050 flexture that metal fatigue will set in if I use the wrong material. Thanks! Too, is there a set of drawings somewhere that you have made public? Derek

[@Stephen1455]

Do you ever use stubby drills, really like them in cobalt?

[@CalvinoBear]

Regular shoulder bolts vary quite a lot, up to 3 thousandths below nominal. For a better fit, the precision ground shoulder bolts available on McMaster are reliably within 1 thousandth under nominal.

[@keyen3]

@NYC CNC an ergonomic mouse such as an Anker vertical mouse, or thumbwheel "trackball" mouse goes a LONG WAY towards reducing the strain on your wrist/arm/whatever.

[@martindunschen6487]

Tell me about what you use on your arm for your tendinitis? What kind of brace is this and does it make a difference?

[@Sketch1994]

6:20 Coolant can actually damage carbide tooling by...cooling it! The only reason you let coolant on the cutting edge is that the right coolant on the right coating will prevent adhesion and consequent build up of the workpiece material. In most other cases it just flushes chips.

[@Sketch1994]

Specially in milling applications the big temperature difference of going between shearing a blued piece of metal to chilling in a pool of coolant while the heat is concentrated on the main rake causes small cracks and notch wear on the cutting edge. At least that's what Sandvik says and I tend to believe them when it comes to machining!

[@chiefmachining7972]

Yes it does it. Thermal Shocks the Cutter

[@chiefmachining7972]

chris0tube ok never said it was coolant fault i said it will thermal shock the cutter

[@chiefmachining7972]

chris0tube I'm high production shop and no that's not reason at all when cutting ferrous material with correct coating the cutter needs get hot enough for the coating to work when you enter the cut the endmill is at certain temperature but when the cutter leaves the cut the endmills flash cools this causes thermal shock which causes micro fractures in the carbide. That is why you hard turn or hard mill (58 rc+) with no coolant just air to clear the chips from the cutter. The endmills and turnings inserts will glow at the tip

[@chiefmachining7972]

chris0tube For some reason you can't post links easily on KZbin. Bunch of evidence and stuides done you will get thermal shocking and less tool life running flood coolant on ferrous materials with these cutters

[@puddingpimp]

Careful with the wrenches too! I tore up the tendons in my left wrist forcing a shopmade tap wrench with too short handles and it took months of pain lifting even the lightest things for it to heal, and it will never be "good as new". Go for a bigger bar and don't overstrain yourself.

[@leemessina80]

Need to get yourself some stub drills.

[@sinadaneshkhah8537]

Hello Thanks for your helpful videos. Ihave one qoetion: The harden pins that you leted on the bottom is good if thay be big or small? Best regards sina von Österreich 🇦🇹

[@tracypoore9214]

I had that problem with my wrist couldn't and wouldn't give up my mouse. So i changed my mouse to a logitech M570 it took me about a week to get used to it. I am now on my third or forth one and it takes me over three years to wear one out. And no more wrist problem

[@tho1efx]

I really found that IMAK's smartglove really helped me a tonne after I recovered a bit. But the first thing to do is reduce the use of that hand and immobilise your wrist for a few weeks. Just be mindful of it. (All this assuming it's tendonitis in your wrist not elbow)

[@twobob]

I had tendonitis for a year. tried using my left hand on the PC, several specialist mouse solutions, in the end just ramping down my use by 30% for a while was enough (developer back then)

[@nicklong9985]

Anyone know how wide it is?

[@newsogn5148]

I once had tendonitis in my knees and my heels, I feel ya on that tendonitis.

[@jammi__]

Switch to a trackball; better ergonomy and generally superior pointing device. There are many different styles, my favourite is the one in Logitech Cordless Optical Tracman. Too bad they're discontinued, which basically made them 5-10 times as expensive as they used to be, but if properly maintained, they last for decades. Mine's ≈18 years old by now and still going strong.

[@jimsvideos7201]

...The doc didn't suggest a SpaceNavigator did he?

[@jennitro]

Have you tried a trackball rather than a mouse?

[@toddmckenney4511]

Hey John you should consider switching to a Wacom tablet instead of a mouse.

[@HyzerGlen]

Why adaptive clear the holes? The boring feature is literally for this purpose.

[@chrisjh777]

I has RSI from heavy use of a normal mouse. I switched to a "Vertical" Mouse 5 years ago, made by Evoluent. Not cheap, but no more RSI. Theory is that using your arm with a horizontal mouse in a partially twisted position is not good. Your arm needs to be a natural "Handshake" position.

[@larsmoeller391]

I work metric and have learned to predrill with 0.2mm less than the reaming diameter

[@georgedennison3338]

Re: tendonitis Try raising your mouse pad off the surface of the desk. Try different thicknesses of books to see what is best for you.m Also, make sure your forearm is supported by the desk. While it is bothering you, freeze some paper cups of water, and use them to ice massage the tendon. When it's really killing you, use an ice bag. Oh, yeah, when you want a nice fit on your shoulder bolts, remember the old carpenter's rule: measure twice, cut once. In other words, measure the damn thing, first! LOL...

[@agdtec]

You might try using a different style mouse for your tendonitis. I like the Logitech WIRELESS TRACKBALL M570 Which I use all the time. But I have a friend who uses the Logitech Rechargeable Touchpad T650.

[@advil000]

I've used a mouse every day for almost 35 years. First, figure out why your mouse ergonomics are so bad. Fix your chair/desk height. Spend time and money to make it ideal. You work there for hours a day. Get your wrist and arm down in line with the mouse and have your wrist break at a good angle. Get a good soft gel wrist pad. If you lean your arm on your chair arm while working, wrap a good piece of foam on that chair arm to spread the load from one point on your arm or elbow. Get a Flextend glove and learn how to use it for your condition. 1 minute a couple of times a day can literally cure a range of tendon issues. Also look up 1Mhz ultrasound "skin/beauty" treatment devices on Ebay. They aren't used for women's skin care. They are small handheld medical deep treatment machines, but they can't be marketed that way. With a little ultrasound gel you can use one to promote bloodflow to the inflamed and damaged tendon areas where it's hard to get blood to for your body to repair. It also promotes the breakdown of scar tissues which is great. They aren't quackery. Doctors offices and physical therapists use them for everything from deep muscle massage to speeding broken bone healing in athletes. They WILL speed healing by up to 30%. Which is a lot. Tendons are super slow to heal. I spent a couple of years battling tendonitis from highly repetitive shop work.

[@melbs2008]

...or you could try using a trackball - the thumb version not the finger version. Logitech still make one. Most people don't realise the benefits. They take a day or so to get used to, but what's that in the scheme of things? (I have nothing to do with Logitech - they are just the ones I have used for a decade)

[@survivalisme88]

When I did my apprenticeship I got taught to never peck when reaming.

[@GregsGarage]

Switch to the left hand on your mouse brother... A couple days of getting used to it will equal years of no tendonitis.

[@attainableapex]

Try a Logitech mx master mouse. It turns your wrist enough to help and not have to use a vertical mouse or one of those rolly bar mice. 70 bucks and it's got good software for the buttons for short cuts

[@brandonfedorick8106]

Agreed! Mice have always made my wrist hurt, and for a long time I used trackballs, and later on the Apple trackpad because I found them to be more comfortable for long periods of time. But I picked up the MX Master about 6 months ago and I won't be going back.

[@TheMetalButcher]

No need to pilot drill. Just go for the size you need. We're not talking 3" drills here, B is a small drill. A machinist jack probably would have solved that chatter BTW. Like you said, prevent that resonance. If you can preload it upwards, it can't start vibrating.

[@jasonstokes5469]

Using a track ball helped me lots. Pick yourself up a Logitech M570, small learning curve

[@stuarthardy4626]

This difference of opinion re imperial v metric needs to be put in context the USA is still predominantly imperial ( although I think that much of the new products are metric for export as a example ) the rest of the world is mostly metric , so both flavours are valid I was taught imperial but now I think in metric ( all my machine are native metric although the dro slows them to be bilingual. I am afraid to say this but it’s not only the people from USA view these videos that John puts out and the world does not end at America’s shore line Please live and let live both systems work history has proved that what you are used to is the best for you whatever it may be but they both get the job done after all they are just numbers we make parts to , if the numbers part/print match life is good Sorry if I have offended anyone

[@Max_Marz]

Tool pressure tool pressure tool pressure! Harder you push the machine the harder it pushes back.

[@dylanrink3130]

good vid, but I gotta say I'm pretty disappointed that we never get to see the haas actually do work, shredding metal like my garage bound 40 taper amera-seiki

[@maesto]

Tendonitis: Try a vertical mouse! But first get this arm some rest!

[@phranklyn]

RPM, not RPM's

[@AmishSolanki]

I bet your doctor prescribed you to use a spacemouse instead. 😁

[@AndrewPrice2704]

I have a 3dconnexion spacemouse too. Fantastic for CAD/CAM :) Much easier on arm than numerous mouse movements.

[@williamthrasher8540]

Try increasing your vitamin b-6 intake it should help

[@seimela]

there is too much info on this video .......I have to download to watch many times ....at least for a beginner
