MI-WS-5302-22-202309:00 AM1.01" inch dowel was the only size I had on short notice. I am also more familiar with measuring in mm and then converting to inches since it is more accurate than using fractions. Just saw the new method this morning and we are now in the process of an ice storm so will be able to report tomorrow morning.

NH-MR-6801-04-202302:30 PM0.87Dowel is same as CY 2022, but has been out in the weather for a year. Horizontal width is 0.87 at 4, 8, and 12 inches. Vertical width is 0.82 at the same three points. I suspect aging and/or swelling due to wetness. It's been VERY rainy here. Dowel is 42" off ground outstanding in its field, attached to a 6x6" PT post, pointing north.

CAN-BC-7912-15-202210:30 AM0.75Dowel points to the NW. Dowel is mounted on 4" x 4" post that also holds the RA gauge and is canted at a 30º angle downward as recommended in the peer-reviewed paper of a study testing this approach. Using digital calliper with precision to 0.01 mm: 18.96 mm converts to 0.746" diameter.

MN-BW-802-09-202205:15 PM0.75I have 4, 8, and 12 inch markings on dowel. Using my Cen-Tech model 47257 six inch digital caliper, I measured at 4" mark: horizontal 0.7485" and vertical 0.749". At 8" mark: horizontal 0.7465" and vertical 0.7485". At 12" mark: horizontal 0.749" and vertical 0.7495". Site is rather blocked (or over-protected) from north and northwest winds, but it is completely exposed to east-northeast, east, southeast, south, and south-southwest winds.

9X6CH02-03-202204:00 PM0.8Dowel installed and initial measurement.
PA-NM-302-04-202207:00 AM0.8If the measurement is to the nearest tenth of an inch, then the measurements I took today are mostly useless. The actual thickness of the dowel horizontally is 0.750, and vertically 0.755, thus the 0.8. The measurements over the ice were, horizontally 0.837 and vertically 0.895. Rounding to 0.8 horizontally would mean that there is no ice (which is ridiculous), rounding to 0.9 for the vertical measurement would at least show that there was some ice. All in all if the measurements are to the nearest tenth of an inch then small accumulations of ice will be missed. And this is one of the thicker coatings of ice that I have seen here. For what it's worth my caliper measures to a thousandth of an inch.

The average thickness in the horizontal dimension is 0.79, while the average thickness in the vertical dimension is 0.77. I attribute the difference between the two measurements to the fact that the dowel is wood and has been outdoors in both a wet and dry environment for several days.

VT-LM-101-04-202201:30 PM.77Noah:

This is my second dowel thickness entry. Could you change my thickness entry to .77 inches (from .75 inches). I just purchased a caliper and it reads .77. I am sure that the caliper reading is more accurate than my ruler reading, and I will be using the caliper for readings going forward. Thank you, Carvel.

VA-HR-3701-04-202209:00 AM1.47I just noticed this pilot Ice Accretion link the CoCoRaHS site. In the Ice Accretion webex, I asked what dowel should be used. The answer then was 1.5". It was somewhat difficult to find that size in a short 4' length, but I found and installed one. I am glad the 3/4" size is what is recommended now - those are widely available. In the picture my 1.5" dowel is shown installed and has snow on it. I took the base thickness measurement from the other half of the dowel that is not installed. On that half, the measurement was uniform along the length so I think it is good estimate of the installed piece. My measurement instrument is a digital caliper that provides in units of 1/100". I could also read the analog scale that is in 1/10" increments.
