Great video!! Can’t wait to see the next video with espresso shots and extraction results with different needles! Thanks again for posting!
Can't overstate how helpful this demo and information was. As they say, the devil is in the details. Feeling just that much more educated now. Thanks!
Just ordered a Normcore wdt v3 which comes with 0.3 and 0.4mm needles. Thanks to this video, I'll use the 0.3mm. Thank you👍🏾🇿🇦
Really informativ video, thank you for the time and insight
If you use a shorter 0.25 needle (instead of the full length), it's actually really good. It isn't as flimsy. I've but mine down to 40mm, and it works like a charm.
It doesn't help with the 3D printed WDT holder, because there's a void space in between, and that part would move too, and if you cut shorter, it'll be too short.
What I do is use a cork from an empty whiskey bottle, use a paper clip, push it deep enough, I make 10 holes. Before I push the spring part in, I alight them all and cut at where the needles part are only 40mm, then send it down to smoothen the edges, so it doesn't scratch my portafilter as bad. It works like a charm.
The holder slack from using thinner needles shouldn't be a problem. You can wedge in a tiny bit of paper or resin to hold it firm.
Great job - thx a lot! it confirms my experiences (with .25, .30 -by Normcore v2.1 and v3.0- and a smaller no name .40 ). I choose the .40 especially for super fine espresso "powder", because even the .35 are bending, so that I have the feeling to have less direct control over the movements
Interesting! I use .4 now, but will consider stepping down a bit to avoid pushing the grounds around.
Thanks for this!
Thanks for the video. After you making me aware of dragging/sweeping the coffee grounds, I removed 4 needles (.30, I think), leaving 4 on the outside and 1 in the middle. It seems to still break the clumps but drag the coffee grounds a lot less. If you have any thoughts on this modification, please let me know. Thanks.
Great video! Thanks! Do you have a suggestion for the best scale to fit on the Breville dual boiler drip tray? Looks like the one you are using in this video fits well
I was deep WDT with 0.2mm and a vertical tap. I was getting rid of all the clumps but I was creating deep channels. I know am only wdt on the top and I am able to grind much finer!
Hey from Lance's video, Im really interested in this WDT tool, let me know how I can order one thanks!
Which one is more effective ? Straight vertical, or slightly angled?
Hey, saw Lance’s video, I’d love to order a set if you have any left. No rush. Thanks!
I used from 0.5 to 1mm, all worked well, 4 needle configuration
I didn't put a centered needle, I think that drags the coffee and creates problem
Used just four 0.4 mm needles and a cork. The pattern is like decent recommends it. Works amazing. Imo too much needles cause these channeling problems or push too much coffee.
Hey, I saw you’re product from Lance video. Please let me know what I need to do get one order!
What dosing funnel is that? Also is that a 58mm portafilter?
Hi, I’m interested in your wdt. Pleased to hear how I can order one!
Any way of getting these in the UK or where to print from?
Many thanks
I have a Levercraft Ultra WDT. It’s 8 x .4mm. Works fine
Are these still available for sale? Just watched Lance's video. I dont have Instagram
Thanks for this great video. I’ve printed off my own version of your tool. The original thicker two piece version however I was wondering if you could help me figure out why my needles won’t extend out beyond the bottom very far. I picked up some very similar versions of needles but they only come out about half as far as I would expect
You probably have the wrong needles. The 0.35x75mm needles are 10.5cm tip to tip w/ a 3cm long handle.
@@jkimmakes I received the wrong length needles. Thanks again for the plans and your videos!
This makes me wonder how a short 0.25mm needle would perform since it would add some rigidity….
0.35mm gang
Hi, how can I get one of these?
How much does portafilter size matter? Would 0.35mm be stiff enough for 54mm, or would the added depth make 0.4mm better?
I currently use 0.4 in my BBE and it seems stiff enough. I was planning on trying 0.35 because it seemed like 0.4 shoved the coffee around too much, almost causing it to pile up. I am not worried about them bending too much.
are you scratching the bottom while you're doing that?
Nice Demo, I thought the 0.35mm needles handled the task the best. Was also wondering how paper filters would hold up against WDT. Do you pre wet the filters?
Yes, I have an example of my paper filter workflow in my "modern espresso" video. I prewet then tap dry w/ a towel.
Is WDT used/useful in other brewing methods? say drip or in a phin or aeropress?
James Hoffmann used one in his mokapot video.
Using the same dose of grinds for all thicknesses doesn't show the differences.
The grinds were first fluffed up by the 0.25, then the other sets simply cut through the work that the thinner pins did.
Each set of sizes should have had there own freshly ground beans to prep.
Still appreciate the time you put into this👍👍
I've been using bottle cork with the 0.4 mm needles with my BBE, seems to work well, would like to get your 3d handle and try the 0.35 mm needles, I'm grinding with an Eureka Mignon Facile, pretty good grinder for $400, nice grinds and really quite :)
Hey there. Could I get a wdt 🙏. Thank you!
What’s in the shot glasss before extraction
Looks like vanilla ice-cream…
thought the Ode was no good for espresso grind
Interesting video, could you please tell me where I can buy the 0.35 tool from, and who makes it... A link would be good thank you...
Champagne cork + acupuncture needles and a clipper. Watch a video on RUclips about diy wdt tools.
I accidentally got shorter needles that are .25mm but only 60mm in length to it seems to be a decent compromise. but I think still a little thicker is better.
Hey so can I use 0.25mm needles instead of 0.35mm because it's hard to find 0.35mm in my place. The 0.25mm is the only option available here so are those any good..?? ( Mainly for Wacaco Picopresso only ) your reply and help much appreciated. Thank you..🙏
Yes, absolutely
@@jkimmakes Thank you.🙏 Then I'll go with 0.25mm.👍
I have used up to 0.4mm and my favorite is 0.25 but i do not have that spread out shape of needles yet i have not seen coffee in between my needles.
Could you share a source for the 0.35 needles? - Found it on one of your other videos 👍
lots of acupuncture needles sellers in AliExpress
@@jkimmakes Did you order a big box of them and are you looking to find a home for those you don't need?
how do I get one from you venmo?
Preorders are closed for now! Check out my Instagram (@jkim_makes). I’ll post a story when they’re available.
I am actually mixing different thickness of needles to get the benefit of each of the sizes and not a bad outcome of just using one size (different coffee roast & grind results needs a different set of needles sizes to face each situation). For that reason, I don't believe in a one size needle that does it all !
I’m seeing a compromise. Who’s going to make the 0.2mm graphene needles? 😂
ended up buying the kit rather than putting it together myself. couldn't seem to find the right needles in less than 100 of them.
the title is a little misleading. you are talking more about needle flexibility as a result of the thickness (and of course material), not about the thickness itself.
I’m using the 0.22mm needles from Sword design. I think I’ve gone too far..
I used to think Hi-Fi hobbyists were the most deranged...
Might seem like nitpicking but channeling is a major problem if you’re making real espresso using the coffee to control the water flow, with channeling, water finds areas of less resistance and the coffee is not extracted evenly, causing a poor shot. This technique is one of few that seems to work and not just in theory
People overthink this crap. Load coffee to half ,quick stir and add remaining coffee. One last stir and tamp. No issues.
How does that change the need for a proper WDT tool? You still need something to stir with in your plan.
Why the terrible siren sound? It's awful.
haha....what adifferent cultura! Anywhere Brasil, Argentina, Spain, Italy with only an espresso machime they make the most tasteful cup of coffee anytime,,,,,,,,,,In the US most of real coffee shop they produce and Ok cup of coffee Marketing makes everything so complicated and commercial orientated. Coffee culture is a simple and tasteful practice for over 1,000 years! Let's keep it simple and real! PLEASE!!!!!!!!!
Wtf are you talking about, coffee from most of those places, as well as the US, taste all burnt. And what are you talking about 1000 years and you mention espresso, tas endejo guey
I just assembled mine. And I've added an upgrade to the handle I'd like to share....
Do you have a messenger or WhatsApp account I can send a couple of photos to? I think you like what I did . 😉
I would like to purchase a WDT tool. I sent you a DM on your instagram! Please let me know how i can purchase one
