The "Sugarbush Thread"

Can we use the box of spare parts from Slidey B and NRX that is in the corner of the lift maintenance building to fix the cooling system on the compressors?

They were already used to fix a groomer

How reliable is GMP there? Both trips I took to SB had power issues. They’re at the end of the lines with no redundancy (e.g., down 100 to the South).

Even if SB wanted a decent fleet of fan guns to supplement air water usage like a lot of areas do, they may just not be able to with GMP.

Not that I want to jinx it, but I rarely lose power at my condo. Even if it goes out when I'm not there, I'd still be notified via an automated e-mail so I'd know about it. A major power issue is typically only caused by a major storm that has either a lot of heavy snow, ice, or wind to take down trees and power lines.

maybe they can use some of the parts from the old Superstar lift they truck up this past summer?

This is the issue I was pointing out. If the Impulses are stepping down to 20 CFM already on 3/4, that is why you guys are making spooge and taking a week to open a trail. The air compression calculations I provided are or equipment built to what is typically shipped to customers. If you want to be able to convert any meaningful amount of water, they need to be valved higher, especially given the wide hydrant density.

I have attached my Impulse flow chart for comparison. These are R5s, but as you can tell, there is more air utilization, and more water conversion in the middle of the curve. We were able to move 31 GPM using 66 CFM at a 20 degree WB per gun.

You can't size your air compression on an ideal wet bulb in late December, and you can't be nozzled/valved for that either. Have to be able to burst in marginal. It is mindboggling that 4100 CFM seems to be acceptable to management for a hill with as much snowmaking acreage as Lincoln. The perceived snowmaking complaints (speed and quality) make far more sense now.

Is it possible to order larger nucs to get more water flow at marginal temps? (If SB had the air)

I’ve seen areas put in temporary Y’s on snowmaking hydrants to get effectively more hydrants. Killington was the master of this with WC snow production especially at the bottom in the arena. I’ve also seen areas daisy chain two ground HKDs to get more production. Yes these last two options are more labor intensive, but that might be what they need to open quicker.
