3 acrows and strong boys.
I've been having a look on the web regarding these supports. So basically you only need to use a support on 1 side of the wall? Presumably these can also be used at 1st floor level?
Some shuttering ply to fit the opening.
To keep the elements and undesirables outs?
I've got a 9" grinder will that do or should I hire a wall cutter (I have a few openings to make)

I've a Makita SDS drill .... ok for a job like this?
Should take 2-3 days . Cut the opening 20mm bigger than the doors, width and height. Insert the strongboys at equal thirds. Insert lintel. You may have to brick up the bearings. A concrete block or cut down pre-stressed lintel will do. Pack the lintel till level then mortar in.
1. Hammer in strongboys at equal thirds into mortar course.
2. Attach props to strongboys and tighten
3. Cut brickwork vertically 20mm bigger than doors (I assume this is for door lining?)
4. Knock brickwork out using breaker
5. Place lintel into opening under the strongboys
6. Pack the underside of the lintel on the bearings with slate and almost dry mix of 2 part sharp sand and 1 part cement
7. Use dry mix and press firmly into the small gap between the top of the lintel and the brickwork above it.
8. Leave mortar to set (a week?)
9. Remove strongboys and props.
10. Make good the gaps with dry mix.
(Have a cup of tea .... been a busy morning
)
Cheers I've got half a dozen openings to make not to mention a few to brick up!
