Can I use one of the spinning mouth pieces on the dynavap (M) model without getting a different condenser ?
The spinning mp is held in place by the condenser which sits in the neck of the tip and goes through the midsection and mp, if there is one.
The condenser in the M is a regular length condenser that accommodates a 62mm configuration. The M stem is 62mm long so there is no room to place a mp onto the condenser.
You have two options; change the condenser or change the midsection/mp configuration.
If you keep your regular condenser you can switch the M stem for a 45mm body and a mp which is 17mm, making up the required 62mm.
If you buy an XL condenser it will accommodate a 79mm configuration. So it will take your M stem plus a mp.
is the draw resistance supposed to be very hard ? I feel like I'm trying to suck a milkshake thru a straw thats too small
The ss M tip has fewer side air channels and no grooves on the tip, so the air restriction is a bit greater than the ti tips. You can file a groove in the tip of your tip to match up with the exterior channels with a small file. You could also increase the depth of the exterior channels to reduce air restriction.
My favorite toking technique is to mouthpull rather than a direct to lung toke. To do this, cover the air intake hole and pull vapor into your mouth like you are puffing on a cigar or drawing liquids into your mouth via a straw. Then once the vapor is in your mouth, remove your finger from the air intake and inhale fresh clean cool air along with the vapor.
normally I would read the FC thread but 1451 pages is a little more than I have time for
Read our best of thread. It's only 2 pages and contains lots of tips and techniques that may be helpful.
