Old Head Freight Train

[fubar]

would I need to get anything beyond the replacement Flower Engine & Injector + glass bowl (AKA Extraction Chamber)

You would need to take the top off to install your coil. Avoided by getting the coil pre-installed I guess.
Not hard to get it off apparently. Saw a youtube review where a dude does it.
Turns out to be comical because putting it back on involves pushing the coil down hard to compress it while screwing the top back on the body full of rubies. Without them all falling out and rolling away. Without a proper tool. At least it was cold.

If that seems like a perfectly normal thing to do before your next hit, then you can install your own coil AFAIK.
Full disclosure. I only got mine today so have not, ahem, yet tried this tomfoolery. Tomorrow is another day.

The metal 18mm male outlet fits 18mm DDave mod glassware for an EQ if you have that lying around.
The glass bowl works pretty well too, so it was worth getting for me.

The coil guard is important for me but I had to improvise until it's back in stock where I live.

Have a question here for anyone who might know: if I want the Freight Train flower experience and already have an Auber & 20mm coil + stand, would I need to get anything beyond the replacement Flower Engine & Injector + glass bowl (AKA Extraction Chamber)? I don’t see any other parts that seem integral to vaping flower and emailed oldhead but haven’t heard back. I don’t want to assume and be wrong and from lurking around here, knew there were kind hearted folks who would know. Kind-hearted folks who are really good-looking and also wise.

looking at their site I don’t think rubies are included with the flower engine, so it sounds like the only thing you would be missing is some type of ball to fill it. i don’t think I’ve received a response from any of my old head emails in the past..

Pretty freakin’ cool that even adding the ruby balls to the cart, the total is still under $150. The VAS-addled fellow on my left shoulder is screaming at me, “Pull the bloody trigger!” but the rational and reasonable bloke on my right reminds me that I‘ve got not one but TWO ball injector-type vapes inbound. My Heavy Atlas has been finished by iDB this week and it’ll be followed up shortly by inverted’s amazing new creation, when the first round of Z8s arrive from Japan. So I’ll do the mature thing and tap the brakes on another ball vape for now but for 150 bucks + ship, it ain’t gonna be easy.

That VAS-addled chap is screaming so loudly he's drowning out the yelling for you to do the same thing from everyone on this forum

Lol. I was gonna egg him on myself but then I thought, he's getting a Heady Atlas and a Z8! He's already facing choices a brave man wouldn't envy!

It's the zirconia Inversion 1.8.

I’ve been following this thread so closely that I’ve read through it a few times. I saw a post on page 6 mention a new FT with more holes. Is there a time frame on a release for a new FT?

I don't think there was any info on an actual release date. Glad I held off on picking up the fusion engine now, more airflow could be a nice change of pace.

Ball vapes seem to evolve at the speed of light these days. I wonder what’s on the horizon. I might end up with the current iteration as I prefer a slightly restricted airflow.

a slightly restricted airflow

Tried to compare it by sucking on an empty bowl while cold and comparing it to some other VAS spoor on my desk.
It is restricted but that's one of those subjective/preference/taste things that won't suit everyone...
Subjectively, it feels about the same as sucking through an underdog stainless steel wand - about 11-12 mm diameter or so - if you have one of those handy. Perhaps a thickshake straw feeling?

Anyone else got a way of describing how restricted it is?
Larger balls might make it a little less restricted.
It might be possible and safe to adjust the top plate
Drilling titanium at home for fun might not be so easy or safe.
New (if there's room?) or enlarged existing holes will make some difference.
Then there are the similarly limited holes in the base.
I've no experience - or need to try right now.
Likely a stupid thing to even contemplate...

Hi, came back to report my findings. I don't think that a PID controller upgrade improves the performance of the vape and if it does for me it was negible, however some QOL improvements are always welcome. First the knob, I don't like ramping up the temperature to enjoy the terpenes, as a medical user and long time smoker I like one hitters so I can keep up with the daily grind, BUT when is made this easy to change temperatures it's hard not to try it and oh boy I swear I've never had a hit so full o flavor before. Second function I liked is the auto shut lff feature, I've left my train freight turned on the whole night and part of the day. I won't lie, navigating through the menus is a pain in the a** and the fact that you need to remember a code to acces them makes it more complicated. To summarize, I don't think it's necessary to "upgrade" the PID, if it's your first ball vape or you are as clumsy as me go ahead and treat yo self, but even then I would argue that is better to get another head, but that's another post.

P.D. I double down on what I said about the TF being the closest vape to a bong hit I,ve ever had.

One of the things I noticed about the regular engine is that it isn’t the best for every water piece. My medium sized bubbler with a perc is less enjoyable than my large tube without a perc, so you can run into too much restriction at least for my taste. Thats the main reason I want the new engine as well.

Interesting - thanks! Have a kludged autoshutoff enabled on the smart plug - absolutely agree that is essential so it doesn't burn down the house.
I can dodge that major reason to upgrade. However, as you say, those tiny buttons get old quickly but as long as I'm not regularly fiddling with parameters, I can live with them.

On a related note, I have been playing with autotuned parameters compared to the stock settings on the standard FT pid for a few days now.
I prefer a relatively low set point of 345C and sessions that last a couple of tokes to finish 0.3g with lots of flavour and zero combustion, so my observations may not match those at higher settings.

The stock PID settings reach the set point slowly - creeping up to it with little overshoot.
The autotuned settings will go way too hard and overshoot by 10-15%, but that "bug" is a feature because you can start the session while the PID is letting the temperature drop to the set point, and I quite like that effect...

Bottom line: Autotuned PID parameters may be worth trying if you enjoy that kind of marginal fiddling. The difference to the "time from cold to ready" and the stability once it reaches the set point is marginal/minor in my experience.

Hello,
Just ordered the FT and wonder if a burn off is necessary. Looked online but couldn't find any info on this. If so, please advise how to perform the burn off.
Thanks in advance!

The instructions describe a recommended 10 minutes at 710F to burn off any leftover oils so yes, you should probably do it. No big deal. The coil on mine was slightly greasy and gave off a tiny bit of visible smoke in the very first minute but nothing else obvious after that,

 

[emigre]

Would someone care to give some tips?
Received my FT yesterday, did 15mins burn off at 700. Then let it heat soak at 650 for 30mins. Set it up exactly the way Sneaky Pete did i his FT video with the Cube and dry herb catcher.
Slow pulls yield no vapor at all even after 20 seconds.
Normal pull yields very wispy vapor after 10s.
Extreme pull yields vapor after 4-5 seconds.
Experimented with stacking but wasting some vapors, and it just doesn't seem right.
What could be the issue here?
Thanks in advance!

I use my TF at 685, try cranking up your temp and report back. Another option is to get a short inyector bowl, the one that comes with the TF is tall. If you don't wanna spend anymore just add more weed to the bowl. There's a guy that sawed off the inyector part of the TF and said that it helped him to reduce his temps. Hope anything from the above helps you and that you get the hang of it without problems.

What does you abv look like? Is your coil loose? Mine seems to produce vapor as soon as I start hitting it when I have it set at 650.

Is the weed packed or loose? I've noticed that to get a decent extraction from the FT with my various glassware including the stock adapter, the load needs to be packed lightly enough to allow the entire weed mass to heat up by conducting the heat that arrives by convection from the hot air stream.

Thanks for chipping in!
My abv is a little uneven, some scorching on the top layer. I did tamp it a little tight I suppose... I'm not sure if the coil is loose, certainly doesn't look like it is.
Anyway, I packed loosely last night. Had it heat soak at 650 for 30mins. I found that I always need to pull really hard to get the vapor going. Each strong pull is around 5 seconds and I'm out of breath, then I may have to catch my breath again to inhale the collected vapor.
Do you both find you have to pull hard? Or does sipping also work?
I will add that I find the coil heater isn't very hot (not sure how hot it's supposed to be though). I was able to touch it for half a second to a second without burns or pain. Not going to hug it though.

Thanks again!

Maybe your coil is damaged, it's very hot when in use, you can't touch it on purpose without burning and putting off your hand

My guess is that when you are toking, the glassware where the weed is remains cool?
Is the same glass really ouchy hot after extracting at a decent temperature on other devices?

Metal at 650F will cause second degree burns within seconds of full contact. That's a dangerous temperature for flesh and if you can touch it without a burn when the PID reads 650F, you are either made of titanium or it's broken. I can feel serious heat radiating off mine if I wave my hand within a few inches of the fully heated (345C for me) coil.

If you have a wattmeter that you can plug the PID into, you should see it drawing up to 200W when it's heating up - mine glows red like an old electric coil stove top for part of the time while heating up and it definitely works

It sounds like this might be the issue, I bumped my FT with my arm and knocked it over while it was at 650 and have a scar now.

The local supplier was out of coil shields...so when I realised what a potentially dangerous toy it was, especially for a well medicated fool like me, I ... improvised... https://fuckcombustion.com/threads/old-head-freight-train.52197/post-1679813 - t
Looks terrible but actually works pretty well for me and I have no new scars. Yet.
