Mounting walk boards on 2x4 stud walls to finish eves

Loose Ctrl · Sep 17, 2018

I need to finish eves on a building that is tight against another building. There isn't room for a ladder or scaffolding. My thoughts are to temporarily mount my walk boards to the studs since the building has no siding yet. The studs are on 16-inch centers. There is blocking between the studs 2 feet from the bottom and top plates. The wall is 8 foot tall and 12 feet long. It will need to support my 225lbs with my tool belt of about 15lbs plus sheathing of about 40lbs.

Does anyone have any ideas?

I have used pole jacks or pump jacks in the past. You need 2-3 ft of room next to the wall. They climb up a set of two 2x4s nailed together.

A friend of mine made a set of brackets. The top portion hooked around the studs of the wall and the bottom portion rested against the outside. A couple of screws held them in place. Only useful in new construction where the stud is still open.

Will Roof jacks with in a vertical position ?

might be easier to make up a couple of 2x4 saw horses the width of the opening and throw some 2x10s across them. At only an 8 ft high wall, not like you have make them very high

I'm familiar with pump jacks. Not quite enough room. I'm not sure where to get them.

The studs are open and I thought of a similar bracket made of 2x4s.

That might work but may put me to close to the wall. I have some lumber around. I could make some bump outs with 4x4s. The wall is only 12 feet wide. It would take four 4x4s and four roof jacks to support my weight, IIRC. I would do half and move over and do the other half.

I have a set of 36 inch high sawhorses. That deal is a no go. I need to get into the eves of a 7:12 pitch roof of a building with a 12-inch tall foundation on the lower side. Put that 8-foot wall in there and it's about 13 foot to the eves. I measured and I need to be at least six feet off the ground to complete the work.

2 36” 2x4 nailed on the flat into an L shape. Cut two triangles of 5/8 ply and nail well onto the L. Pre drill two holes in the vertical 2x4. Lag into a blocked stud or spike with 30d. Insert a proper length 2x6 with a point cut on one end into crotch of the L and other end dug a bit into ground as an angle brace. Make as many as needed. Don’t throw out , use for other things.Used myself many times.

I would rent a set of these.

The local rental place will have them

You will need to sister a 2x4 to your studs but that can tempoary.

I have to laugh. I just finished a video with Bob Villa where a man shows how to build those. I don't have enough room for the 2x6 brace. Less than three feet of space.

I don't have space for pump jacks. Those aluminum ones look the business though.

Sure you do, put the braces against the other buildings foundation (ask nicely first of course). That is actually better than sticking them in the ground.

A picture might help get some other ideas.

3’ is enough room. Get it done than post us back your pics

you could easily mount 2x material horizontal properly anchored to the stud wall with a 'kicker' bracket to do the job. Not osha approved but done properly its safe. Having said that, we used to do them like that in tight spaces until the guy nailing the bracket on, nailed it to sheathing instead of the stud. EPIC FAIL, my brother ended up out of work for a year with permanent damage! I saw a commercially available version on this old house that hooks through the stud with a cross support piece on the room side. They were pretty nice looking contraptions.

No pics. Sorry fellows. Job is done. I took two 4x4 posts that were 12 feet long and cut them in half. I lag bolted 2x4's all around them at the top, bottom, and center. Maybe a couple inches in from true bottom and top. Leveled her up with some cedar shakes and laid on my 12 inch wide walk board. I used my 6-foot step ladder to get up there. The scaffold was roughly 30" wide by 5'6" long. Fit just enough to get he job done.

Thank you all for the good ideas. I broke down and spent some wood supply I had squirreled away.

Sounds like its too late now but scaffold is availiable in 29" wide x 6' long sections. https://www.homedepot.com/p/PRO-SERIES-6-ft-x-6-ft-x-29-in-Multi-Use-Drywall-Baker-Scaffolding-with-1000-lb-Load-Capacity-GSSI/100645165?MERCH=REC-_-PIPHorizontal2_rr-_-204588148-_-100645165-_-N

I needed cheap.

I'm confused.....how did 4 - 6 foot long 4x4's become a scaffold 30" wide with a 12" wide walk board? If you don't have pictures, it will be hard to visualize.

No pics. I did something similar to the pic below. I omitted the casters and X bracing. I used 4x4's for my corner posts. I made mine 30 inches wide to be stable. I slid my 12-inch wide walk board on top. If it tipped, it would only move a few inches before impacting a solid wall. The ground is fairly level but lumpy, you know, a typical southern yard. :lol_hitti
