What you need to install Simrell MVS stem on ANVIL:
- Extra Anvil Heat shield
- Thin rat tail file, fine grit
- Thicker o-ring to replace one under OG mouthpiece. I got pkg 50 from Amazo for $10 delivered: uxcell Silicone O-Ring, 8.5mm OD, 5.5mm ID, 1.5mm Width, VMQ Seal Rings Gasket, Red
- Simrell MVS or Simrell Blackwood stem.
- DV fat mouthpiece (optional)
1) unscrew Anvil mouthpiece and set aside. Remove o-ring near mouthpiece end (only One o-rig) and replace with new fatter o-ring. This fatter ring will lock the MVS in place when everything is installed properly.
2) MVS stem diameter is slightly too big to fit inside the extra heat shield. You need to file off about .001 around the inside diameter of the extra heat shield, the end without the threads. File off just enough inside the extra heat shield rim for the MVS to snugly fit inside the opening. Work in circular motions with the file. Go slow, check the fit and repeat. Very little material needs to be taken off the inside rim, takes like 30 seconds of filing. You won't see any file marks when installed, no worries it's invisible.
3) After filing is complete and MVS stem is able to slide into your extra heat shield, pull the MVS and extra heat shield apart.
4) Screw the extra heat shield onto the exposed mouthpiece threads - backwards from the still installed OG shield.
5) Tricky part - With extra heat shield now threaded on, slide the MVS into the hole and over the o-rings.
*** I find a very light lube of the MVS inner diameter end hole helps with the sometimes tricky 'slide and lock' install of the MVS over the fatter o-ring. Don't directly lube the 0-ring, it makes them stretch, you want em firm. I use a q-tip and a smidge of Eds Ass butter to lube the MVS inside rim.
6) With MVS sliding into heat shield and over fatter o-ring - give a few rotations of lubed MVS with very light pressure to lube the seated o-ring -- Now PUSH HARD & TWIST - You will hear the MVS 'click' into a locked position on the o-rings. Sometimes you have to fuck with this step a bit but trust me its worth it! SUCCESS!
It's really a simple modification to let you use a Simrell MVS or Blackwood stem on your Anvil ...... Made somewhat complicated by a wordy set of instructions. WTF you expect ... I'm baked! It's really a worthwhile addition to the Anvil if you have a MVS kicking around collecting dust. Makes Anvil native hits smooth and significantly cooler. Bong rips are supreme! Enjoy!
