At 35 metres long, and 12 metres wide, the Wangi Men's Shed is shaping up as one of the biggest in the Australia-wide organisation.

This week, the Wangi Wangi men marked another milestone in their five-year quest for a shed when a mosaic sign crafted by retired TAFE teacher Peter Cattalini was erected.

"In another two weeks the shed will be at lock-up stage, then we can get it fitted out," Wangi Men's Shed treasurer Alan Collins said.

The 75-strong group has about $20,000 worth of machinery and equipment on order, including lathes, welders, planers and even a car hoist.

"Once the shed is completed, members are ready to help with all of the other work such as building shelves, installing the machinery, and sealing the concrete floor," Mr Collins said.

The shed will include a bathroom and kitchen, as well as a meeting area separated from the work space.

"That meeting area is where members will play cards, talk about the good old days, solve the problems of the world then go home," Mr Collins said.

It's been a long time coming, but Mr Cattalini said the shed was proving worth the wait.

"This is one of the biggest we've seen," he said.

The health and safety of members is a priority.

"We've trained 17 of our members in first aid so that when we open the doors there will be enough blokes here to look after us," Mr Collins said.

The men hope to open the Wangi Men's Shed by Christmas.
