Chief judge and Welsh official Martyn David will monitor the event from an office at home in St Athan using audio-visual link technology - as was used in the successful solo records set by New Zealander Megan Whitehead in Southland in January and England shearer Stuart Connor in Cornwall in July.
The technology means the record attempts can go ahead in the pandemic, as it meets the rules required for an international panel of judges.
Wet weather disrupted the drafting of the lambs on Friday, but organisers are confident it'll be all-go for a wool-weigh in the woolshed on Tuesday afternoon when a shear of 20 lambs must average at least 0.9kg per lamb.
After preparation already in the shed, the crew are confident the minimum requirement will be met and the record allowed to go ahead the next day, starting at 5 am and finishing at 5 pm.
The five runs during the day are separated by one-hour breakfast and lunch breaks and half-hour breaks for morning and afternoon "smoko".
