Can't help you there. IH all the way :rockon:

Something new to throw into the fray. Certainly bits and pieces worthy. Apollo II guts. One cap, mini coils, mosfet switch. Fairly basic if you ask me :tup: And it follows the ZVS schematic. What is that in the upper right [U1] I wonder. Is that a debounce element? I might have stuffed...

Cool. Close enough... Inner cooler not DV compatible is fine for my ask :peace: Thanks :cheers:

I tried the '18-M in its default state. 2 minutes later I fixed it to fit my taste :clap: 2 month later and I'm making stems :tup: 2 months after that I learn what made it my own! :rockon:

Cool. Got an email in to see if I can order some of the inner coolers. Is the inside diameter of a Vortex the same as a DynaVap condenser's ID?

I just noticed one can buy the twisty separately when available for about $20. That is worth building it into a home-made stem. Are the wooden Simrell stems lined with Ti or stainless or do they all use the DV condenser?

@LabPong Yes. Lower power bricks can act like current limiters effectively lowering the voltage during high current draws. This is hard on those supplies because they are not designed for current limiting. The saving grace is the low duty cycle of heating a VC. My first setup had really...

CCD=screen, yes. Look at the edges where the holes are. Normally they would lay flat on the bevel in the bottom of the bowl. Most people are perfectly happy with their VapCap. They have a technique that works for them. I am only addressing those what don't like their current airflow. I...

That is a '19 C-Vap you got. Turn the CCD over and put it back in with a 5/16" tube if you got one. I promise you it will improve the C-Vap. I suspect the same with the '20. Bottom line is that air bleeds in gobs with only a small crack. The cap is restrictive but nothing like plant bits...

I love it when answers come just for the asking. Thanks again George! https://www.youtube.com/watch?time_continue=9&v=hubNTLR4ivE&feature=emb_logo The circuit is identical to the mosfet switch with a reduction in both the capacitance and inductance (2 coils w/ toroids) in the heater section...

Ah, yes, the C-Vap is an earlier blem version. Probably a '19 or maybe even an '18 or '17. The fact that you are experiencing the same with both probably says it is 'normal' or within the range of normal. Once you figure this out, you'll understand what it took. I got mine worked out to the...

Sorry I mis-spoke and changed 'cap' to 'tip' The tip should be an octagonal shape or maybe 10 sides. They replaced the grooves of the previous generations with the n-gon style. If for some reason your tip is round, I can see it not drawing well. Somehow that would be a serious outlier...

I wonder if somehow your '20 tip was mis-machined. If it has flat faces on the outside of the bowl, it should flow air through the cap.

Welcome to the forum @kronicking - First of all, don't pack the bowl to tight. Does the airflow improve if you use a smaller bowl setting with the screen thingy known as a CCD? I've solved this on both the '18 and '19-M but I am waiting for the '20 to see if things changed. I turn my CCD...

@LabPong - yes, you can use a lower voltage brick to reduce the Caldron's output. Try to stay over 8 volts. 2s 18650, 7.2-8.4 volts, is a very tame IH. I haven't played with rheostats yet. You might be dropping as much as 50 watts across the device.

"...and exactly 50,000 posts later a man thanks George for all he's done" - Fates :rockon:

Thanks. I'll give that a try.

Good to know @AcidFlashbang - I have a 1/5th going on 3 years now and still enough for one more. Basically 2 shots for a clean grinder. Same nasty smell or is it different?

Really!

@LabPong - I really wasn't trying to piss you off with my earlier response. I am serious about dialing in the speed at which the IH's heat VC's. You can do that with the Caldron.
