- Tappy Tap Tap
Coolant oil content was low, I do not usually have galling issues like I did that day.
M10X1.5 taps in 304 Stainless. Need some sturdy spiral flute taps to try out. straight flute are not really made for this abuse but spirals seem to snap easily, kinda a catch 22
That can't be anything other than an AvE reference
Wonder if that tap is a skookum choocher
I got ban from AvE for suggesting it was turning into a patreon only chanel!
Hi Ed,
Glad to see you upload a video. I miss the old days, but I understand working a full time job leaves a lot less free time.
Best wishes,
Sdeery
2 videos in a one day yes
Nothing like sipping my coffee watching Ed work with some steel.
I broke my favourite M3 tap last week.
RIP Sutton T1140300, 2007 - 2019. You will be missed.
Small diameter taps could use some thicker Mobil (or similar) for lubrication. Diameter halves, max torque drops to 1/4. There should be adjustable torque controller in small tap machine.
@@FourSeasonsHD Trefolex works really well, its my usual go-to for stubborn holes :P
Skookum
Always love new content. You should do a video explaining how you stop all that milk from going sour when cooling off machining work.
You need way more lubricant than what coolant mix can provide (reading your show more) to power tap. Heaps more. You essentially have to glop it in, no other way. Think of power tapping as a perfect mix between force, heat dissipation, and lubrication (to be read slip coefficient). In power tapping the relation (a triangle diagram) is heavily skewed towards lubrication with force coming second. Cooling the part is third, mainly because you're supposed to be in and out, quick, let the chips do the cooling for you. And spiral flutes...they work, but you cannot do that kind of jogging with them. That's their weakness, their ability to absorb the twist is minimal at best. But if you fix your speed and feel and don't go back, well, they work.. One last thing, which is not dependent on you, if you tap on a lathe, you need a VFD to accelerate for you. Short acceleration, but still better than the classic jog (and slack pull).
I have increased the coolant flow and lube oil content and its working well. as you mentioned I cant run spiral since they love to snap.
I a kinda stuck with the lathe as it is since its not mine, I cant just go out and build a 10Hp VFD conversion for it :(. as much as I would love to improve the controls that is.
So far so good tho, I am doing another batch of 50 shafts tomorrow, I will see how it goes with deluge coolant and higher lube oil content. running straight Trefolex tapping fluid its fine at high speed, but that shit is sticky and has to be applied manually, not to mention washed out before I can loctite bolts in the end later on. I hate the stuff
Love the sound of that motor lol
Dam it!! I wanted you to test if the thread works with a bolt.
first one needed re-chasing but the rest were fine
it has 10mm of thread going into it with blue locktite, simple spigot shaft for a pool cover roller.
If the tap snaps easily, I might suggest testing with thick Mobil grease rather than liquid. Torque needs to come down and it might happen with stronger lubrication.
My butt puckers every time I see this done, especially on austenitic stainless. I know its common practise but extracting snapped taps suck
thankfully these parts are just bits of 20mm rod, cheap enough to throw a couple in the scrap bin each year when a tap inevitably shatters.
Sees this, wonders how the tap doesn't break... (My own experience with home-shop machining thus far has kinda been a graveyard of broken tools. I am prone to get a little paranoid... (So much HSS tooling, which cuts metal fine one moment, and then for little obvious reason shatters like glass; or random things like a cordless drill tips over and then the drill-bit breaks off; ...).
Also wondering, sorry to be a burden if I am, do you still have the bmw 735? I watched some of your videos on it with the engine swap and all. Have one myself that I cannot seem to part ways with despite its problems.
Love your videos. Cheers from usa
No I do not have her anymore. long gone.
@@Aussie50 I hope it was a sweet farewell.
One needs two 90'ies Bemers, one to use and one to service.
@@beaustoioff6182 I sold her to a friend of a friend, he had a couple of runners and a couple of parts cars, always looking for more. he fixed her up with a new torque converter and distributor and put a few more years use on her before buying an X5 4.6is
nice
I want to test just that on Emco miniature lathe. Hopefully the tailstock follows the thread.
Almost thought this was going to be an ASMR video lmao
One powerball
oooooh, squeaky stuff!!! :S
Dose that yellow guard anoy you?
When I am running coolant, its nice to keep it under control, but for general dry turning its a pain in the ass , but Worksafe will not let me remove it :(
Better than porn!
that is cheating lol do by hand its not so fast lol and hard work
yep, spent many years doing it by hand, usually M12 - M20 for mounting and modifying gravity casting dies at the foundry, fun stuff :D
