19) Remove bottom-side of catch guide

20) Bottom side removed

21) Widen the rear suport until the new barrel fits

22) Widen the middle support until the new barrel fits

23) Use superglue to attach an extra piece of rubber (from step 32) to the end of the barrel.  This may also be supported with electrical tape.  The idea is to attach it in such a way that the 10 inch piece will still fit on, but will make an airtight seal.  Note the flat area at the bottom which is on top in the next picture.
24) New barrel assembly in place.  Note: sand off just enough plastic from the top of the barrel just under the catch to allow it to move freely. (dont sand all the way through the barrel!)
