I played hvac tech this morning, out with the old undersized main trunk, and in with the new correctly sized main truck, and most importantly the supply line for the bedroom in the new addition. 1 more step to final inspections !
The trunk went from a 8x14 to a 8x8, with 3 rooms being fed after the reduction. Rooms were always colder in the winter and somewhat stuffy in the summer. When I reattached the supply lines to the new trunk, I was able to stretch the inner flex anywhere from 6-12" in each line. If the flex duct is not stretched probably, this creates added resistance and basically takes a 6 or 7" line down to a 4. I can already tell a difference in air flow in the affected rooms
Then worked my shift at Mainline, and seen these get brought in for consignment. Even though I don't model the steam era or UP/SP, I still had to ponder owning something like these.
Terrifyingly they let @chicken45 wander around the streets of Pittsburgh. Luckily he was being supervised. (Attachment Link) So that's been MY weekend.
Do they allow that type of music in Mexico ?
Did you go to Esther's hobby shop and Primanti Bros.?
Peteski: I think what he's saying isn't actually that the main trunk was undersized, but that the side ducts to the individual rooms were, due to being made from "flex", whatever that means in this case. I assume it's something similar to dryer vent hose.By using a smaller main duct, he could stretch the "flex", which apparently contracts in length by folding internally, so that the inside diameter of the "flex" is larger. That way the rooms get more air.
I get my Gyros at the Gyro Spot in Manchester, NH. Originally they were called G-Spot, but that name didn't last long.Those Gyros have fresh cut fries wrapped inside them. Now my mouth is watering!
Changed the name because most men couldn't find it .........
