The long running VT MAPLERAMA appears to be another casualty of COVID. Its a terrible shame.

after about 1000 holes the tubing might need to be replaced, i noticed the other day. it does work well.

I'll have to get a look at one and give it a try. I like the one I got at Bascom's but it's pretty expensive, $18. It's very aggressive and needs the collar to stop it from going all the way through...

What is your favorite 5/16" tapping bit to use in a battery drill? I use a Dewalt DCD 998. Also where did you get it, how much did you pay? I use a steel collar held in place with a set screw, on my...

I take it the MAPLE RAMA for 2021 isn't taking place?

I am certain the SP22 is good for hobbyists, I need something for a real, profit making, big time operation, that can handle far more than 700 taps, and preferably at 29" hg. I had hoped to hear from...

You are right about no responses about modern vacuum pumps as yet. I have used a Surge SP22 with success. But that is a 22 cfm pump, designed to be used at 15" hg, maybe useful for a maximum of 2000...

I saw several producers using piston vacuum pumps over the years on Maple Rama tours. Are you still using them?

I don't agree that the hot end system is so dangerous that it shouldn't be used. I still like my coffee hot too.

Modern industrial quality piston vacuum pumps are finned and have a fan pully, constantly blowing cooling air onto the finned piston cylinders and heads. Some have a feature, called an unloader I...

One of the reasons I started this thread is I want to use a modern vacuum pump, with parts available, not an antique. And I wonder if anyone else, besides me, thinks a modern, low tech, piston pump,...

Anyone know?

I have used piston pumps but I am wondering if anyone uses an industrial quality one, such as Ingersol Rand, 50 CFM or bigger, and how it has worked out. They are a bit expensive but kind of low...

I have used a Surge SP 22 piston vacuum pump with good luck but it wasn't intended for high vacuum. The one I used had a 2 hp electric motor, 120 volt, I think. I used a refrigeration thermostat to...

I would use two temperature sensors and monitor them both. One would be in the sun, the other would be in a shaded spot, so as to get true air temperature. Sometimes the sap will run if the sun is...

I'm looking for a temperature controler that's web/wifi enabled to start and shut down vacuum pump. Any suggestions?

Anyone use a big piston vacuum pump sugaring? I'm looking at a big Ingersol Rand piston pump to use in my sugarbush. 100 CFM or bigger, no milk room pumps, PLEASE. Its an industrial pump made for...

Are glass lined tanks acceptable for use in sap gathering under current food rules? I want to use a nice glass lined steel tank for a vacuum receiver tank if its acceptable.

I recently saw a maple tubing operation that leaves the spouts in the trees until they return to tap the next season. Then, they cut off the old spout and replace it with a new one. Of course they...

Thank you. I found it online in a free pdf download. Excellent resourse.

Are you talking about a flow meter or a water meter to measure gallons? Flow meters are generally used to measure cfm, cubic feet minute or other cubic measurements. Water meters are a great way to...

Have you tried piston vacuum pumps, like an Ingersol Rand? There are lots of used, industrial quality, piston pumps.

I'm looking for pics of a vacuum mainline sizing chart and a vacuum wet/dry mainline sizing chart. Thanks!
