    Re: (HELP) Need advice on building door hinges.

    Perhaps if I had a press brake I could bend the plates so they are easily weldable and still be able to close with minimal gap between the two opposing plates. I don't so it's wishfull thinking.

    I figured Never liked doors that wouldn't open 'all the way'!!! you're always stressing them and stuff like that... I guess make sure you weld plenty long enough flatbar on them and then kind do a mockup with a small piece that emulates the door before drilling for the mounting holes.

    You should be able to control that gap with just the angle that each piece adjoins the barrel sections??? I think....

    Exactly I'll use a 2x4 the inner skin with the outer T1-11 skin as well as the exterior trim. It's going to have to be long.

    Guess I should have drawn it like this with the centerline of the hinge

    Re: (HELP) Need advice on building door hinges.

    I'm thinking the top one looks more favorable or possibly the lower right one. Thinking I'll have to tack one up to see how it operates in the fully closed and open posiition prior to welding them all out.

    The top one would be best. By using the right thickness of shims and spacers you should be able to get just over 180 degrees of operation.

    Re: (HELP) Need advice on building door hinges.

    I love using those weldable/greaseable hinges.

    I realize this doesn't help N2 but while we're on the topic (and you all know how I post way too many photos ) ....

    Interesting factoid. Hinges come in aluminum AND steel. So if you use them from the same manufacturer you can use one half steel and the other mating half aluminum for applications such as this.....







    where I built an 1/8" aluminum lid for my 10 gauge steel fuel tank's tool box.

    Re: (HELP) Need advice on building door hinges.

    I'm going to start cutting up the flat stock to 6" and figure I can trim them to fit later after all the mounting is figured out. Here is a pic with the 2x4 and 2x pieces of T1-11 sandwiched all together. I'm not sure what trim I'm going to use yet so I'll have to figure on adding the thickness of the trim to the added thickness. Name:  20201212_180050.jpg

    Thinking I'll end up using some cheap cedar fence pickets trimmed to size on the table saw for the final exterior trim pieces.

    My Makita always makes a chattering noise and I had the merits service dept in Hayward ca check ut our fir me and was told it works as it should. I've always thought the edge of the cuts were a bit rough and I do get an edge that needs to be debuted. Does this look normal to any of the makita 12" metal chops users?

    Re: (HELP) Need advice on building door hinges.

    All depends on what you mean by chattering noise.... my dewalt multicutter will make similar cuts although I don't know that the markrs are as spaced out as yours... you might have a tooth or two a little out of alignment??? they do leave sharp edges!! this is the nature of the cutter...

    I 'll try to remember the next time I'm cutting flats vertical to take some close ups.. but I think I have a few teeth chipped now doing something I shouldn't have... I know better too....

    Re: (HELP) Need advice on building door hinges.

    Ok cool, thanks ronsii

    Edit: when ever it starts making the chattering noise I just back the blade off and dive right back into the cut.

    Re: (HELP) Need advice on building door hinges.

    Ok it's midnight and I have to say I'm quite dissatisfied with these barrel swivel hinge things. Lots of play in the hinge.

    The fit up and welding went about as good as can be expected. I have one welded out completely and 3 tacked together. I'll update in the morning with pics of the process of how I ended up welding them up. They'll do the job but the slop in the joint bugs the $hit out me :/. Ok enough rambling. Back to welding

    I used 1/4" spacers and ended up being able to get a full 270 degrees of rotation which is way more than enough

    Again, if you build the frames out of steel tube there will be no sag. I build large entry door out of steel tube and allow 1/4 gaps top and sides and 7/16 at bottom to allow for a sweep (larger depending on type of sweep).

    Re: (HELP) Need advice on building door hinges.

    Anybody use timberlok screws in place of lag screws? They replace 3/8" lags. Lower head profile and about 1/4 inch diam. Draws parts together
    near tightly. An engineer spec'ed them on some.steps I build...I have been using them as general purpose faster since then.

    You could countersink the holes a third the way through and will still be more than strong enough to not pull though the steel and get more clearance... heck halfway through would be safe!!! just make sure you have a socket that is ground flat on the end to hit the bolt heads because a lot of sockets are tapered at the end for a good 8th inch and will strip a shallow bolt head

    I've used them on a lot of projects where we need a lot of depth to get strength... like you mentioned on stair builds and fastening roughsawn lumber and hanger plates for structural mounts... they can work great but do cost a bit more

    Re: (HELP) Need advice on building door hinges.

    Ok, was at the shop a bit ago and saw a piece of flatbar laying there that reminded me of this thread so I grabbed the dewalt and set it on myf250 and chopped away
    6 inch flatbar

    Had to slide the vise about an 1 an half forward to make the 6 inch cut. Also wirewheeled it off first

    The dewalt has kind of a low end chatter... at least that's what I'd call it when it's chewing through a piece of flatbar... but It seems normal for how metal works...
