    Finding an angle

    While doing a repair of a small step-ladder...
    Jonathan's Ladder, back.JPG
    Someone had replaced the back braces with Particle board ( then they happened to step on one)

    Ripped some now Ash lumber...both to repair the broken leg..
    Ladder Repair, matching the end of the other leg.JPG
    Using a half-lap glue joint....nothing fancy here....

    It is when the ends of the new braces need cut..
    Ladder Repair, upper brace, new.JPG
    That I need to match an angle....so...
    Ladder Repair, Sargent's Patent 1875.JPG
    Called a Sargent's Patent July 22, 1873..
    Then needed a dado/rebate on the ends...
    Ladder Repair, lower brace, rebate.JPG
    And do a test fit...no glue , nor screws used...
    Ladder Repair, test fit, lower brace.JPG


    Still have to rebate the upper brace, drill and counter-sink for 3 screws on each end...Clean the area where they will sit...so a bead of glue can also get used..

    Then see what colour they want the "new" step ladder to be...

    Plan right now? Lay in a supply of hardware, use this ladder as a "pattern" and build an all new stepladder...and stain and finish that...
    Stay tuned..

    I don't think that that "Sargent's Patent" is related to the later Sargent Co. that was making hand planes....

    Repairs are completed..
    Primer Painted, side view.JPG
    Plan now is to use this thing as a Pattern...and build one of my own....before I send the "original" back to Grandson to use as a Plant Stand....
    Primer Painted, Leaning, front side.JPG

    And let him decide on a colour...as this is just a Primer Coat..
    Primer Painted, leaning, backside.JPG

    Have haul a 1 x 6 x 6' Ash plank to the shop....will start a cut list sort of thing later....

    First plank has been cross cut....
    new Ladder, 1st plank, parts.JPG
    2 steps, top step...and a blank for the legs on one side..
    New Ladder, leg parts.JPG
    Had to haul a second plank to the shop..
    New Ladder, 2nd plank.JPG


    All these blanks will need to be ripped for final width..ends need to be beveled...angled dados made.....and a small groove milled under 2 steps, to house the all-thread stays....

    Depending on how the next 2 weeks go..I might have plenty to keep me "occupied"?

    Second plank has been cut up...second blank for the legs...and the 2 back braces....
    Ladder Parts, leg parts, to size.JPG
    Ripped for width, and thickness reduced to 3/4" thick...Need to cut the stretchers at the angle required, and a rebate/dado on the ends. Legs will need a miter cut.
    Ladder Parts, step, final sizes.JPG
    Lower 2 steps were trimmed to size..and thinned down to 3/4" thick....top step is at 7/8" thickness

    Ladder Parts, peeling.JPG
    To get to that 3/4" thickness from the rough sawn surfaces.....peel the thickness of the saw blade off of each face...then plane smooth.
    Was a busy hour in the shop...
    Ladder Parts, making sawdust..JPG
    Shopping trip today....to get some better hardware...had to visit the ENT Doc and get a Hearing test...maybe later today, I can start on some joinery?

    Nice couple of projects. No trigonometry required. Lacking a hardware store carrying “genuine step ladder parts”, I shall be interested in your choices.

    New Ladder, leg bracket.JPG
    Bracket to attach the legs to the top step...pivot bolt for the back leg..
    New Ladder, pivot bolt.JPG
    All thread..
    New Ladder, all thread.JPG
    Goes through under two steps...sits in a groove on the underside...through a hole,and then these take over..
    New Ladder, step hardware.JPG
    Keeps the legs from spreading out, when you step onto the ladder...washer sits in a slight recess..
    New Ladder, leg hardware.JPG
    The folding braces, will be cut from something like this.
    New Ladder, Beer Tote.JPG
    First used to carry 6 Guinness Draught Extra Stouts...now carries the small hardware for this Project...

    Stay tuned..

    Mitersaw?
    New Ladder, Stanley No. 358.JPG
    Angle setting is an "8"...
    New ladder, saw setting.JPG
    So I can cut the top and bottom of the fixed legs..
    New Ladder, mitersaw.JPG
    Then layout the angled dados...saw the walls of those dados...and then clean them out with a chisel..
    New Ladder, chisel work.JPG
    Then clean them up level with a router..
    New Ladder, router plane.JPG
    Plane. Then a dry fit...
    New Ladder, dry fit, step.JPG
    Then call it a day...

    Bracket gets screwed to the underside of the top step..and to the fixed leg....Movable leg get the pivot bolt...
    The "8" on the Stanley No. 358 scale is to make a box with 8 sides....about 22-1/2 Degrees...

    Ok...2 steps need a bevel on their ends, to match the splay of the legs...
    Sat. Funnies, step details.JPG
    Front corners need to be "clipped" as well

    Front legs also need a bevel...turning the top and bottom cuts into a compound miter cut....
    Sat. Funnies, Compound mitered.JPG
    To splay the front legs once they are attached to the bracket under the top step...
    Sat. Funnies, needs to move up a bit.JPG

    Underside of the 2 steps, needs a groove milled...
    Sat. Funnies, step brace.JPG
    To house the 1/4" All-thread rod....there also needs a hole drilled through the leg
    Sat.Funnies. drilled.JPG
    Centered in the dado bottom wall....I come back with a Forstner bit, and add a recess to house the fender washers in

    getting down to do a little assembly..stay tuned..

    And, as Norm was known for saying..."time for a little assembly.."

    Brackets installed...legs attached...
    Assembly Time, pivot bolt.JPG
    Could not install the steps...with the rods in place. Had to slide the steps into their dados, until the groove and the holes lined up...groove is tight enough, I needed to drive the rods in place with a hammer...The recesses for the washers were already done......Rods were also already cut for length ( hacksaw) apparently, I had messed up some of the threads as one lock nut was having "issues"....the other 3 went on just fine....
    Assembly Time, fender washer recessed.JPG
    Since that one lock nut took off for parts unknown...a "normal" nut took it's place. (Note to self: Next time, install the nut on the cut ends of the rods, first..then hammer the rods through, remember to add the fender washer, too)

    Backside of the 2 steps.... stuck out enough, they would not let the swing legs lay all the way down...simple fix..
    Assembly Time, Notched for back legs.JPG
    Hammer and a wide chisel to notch this area..test the fit..
    Assembly Time, test the notch.JPG
    That's better....I need to finish up the folder braces...got one started..
    Assembly Time, folding brace.JPG
    These are the braces you fold down to lock the swing legs open, when using a ladder...

    As for the back leg braces...
    Assembly Time, too big.JPG
    These 2 are looking a bit too clunky....so...I will rip one down the center....and save the other for some other project....

    We'll see how things go...stay tuned...

    Spent 5 hours today, going through the Heart Stress Test (Chemical).....as if the drive to and from the Hospital wasn't stressful enough....

    Nothing feeling all that "chipper" at the moment.....at least not enough to be running a drill press, drilling through steel.....

    Tomorrow morning...a Heart Monitor Chip get implanted under the skin....more time at the Hospital...

    Feel better. Heart issues can really make you feel lousy.

    Metal working last night, got bored...
    Had to change to a new drill bit...and..slow the drill press down to "Granny Gear"......Drilled the 4 holes needed in the folding braces....deburred at the grinder.

    Forstner bit in a corded drill, to recess the washers...so I could install the nut...with some Blue Thread Locker...photos?
    Metal work, locked open.JPG
    Metal work, bolt side.JPG
    A drop of 3in1 oil to keep things moving..
    Metal work, folded down.JPG
    Stand the ladder up..
    Metal work, locking braces.JPG
    Then set down on the shop floor, and see how well my 230 pounds works....NO, I never step on a top step of ANY ladder, BTW

    Some of the other tools...
    Metal work, tools.JPG
    Note the fancy 7/16" wrench? Cordless drill was used to drill through the legs for the bolts to pass through...after the Forstner bit was done. Scratch awl was used to help line up the holes, when installing the bolts...

    Still needs a coat or 2 of Witch's Brew finish...and a branding iron, somewhere. Maybe a block plane to knock down any sharp edges...

    Stay tuned...just about done...
