I searched the internet and this forum looking for ideas for my scms station to add extension wings. couldn't find anything till 2 days ago I came across a website with what I was looking for. This is what I started with
I proceed to cut out 2 torsion boxes and notched the pieces like the cardboard that used to be between the cans in a case a beer along time ago. Don't know if it was the correct way but it did work very well I did the assembly on top the saw because that is the flatest surface I have.
I used door hinges to mount the torsion boxes to the scms station because thats what I had.
To adjust the level of the extensions and to help locate the fold out support arms I used 1/4-20 phillips bolts. I drilled a 1/4" hole straight down in the support and drilled a 7/16" hole about a 1/4" deep to accept a nut. Under the extension wing is a washer that is slightly smaller than the head of the bolt. This helps to locate the support arm in the proper place and give it a good bearing point.
Here is the saw with everything folded up
and with the extensions out and ready to use
