    general truss design question

    I am going to let the man lift do the work ... it will lift the end of the cart up to the roof. With one end still on the ground, I can slide them right up onto the roof. The original question was, what is the best way to make the slide/cart. I am thinking two flat trusses like floor...

    general truss design question

    Interesting .... I actually have a vacuum pump. My panels are flat so no issues with a suction cup sticking. The problem is I still would need to get them over to the center of the roof. My man lift will only go over a few feet. Moving the slide along gets them lined up where they need to...

    general truss design question

    They really should not touch each other ... they are painted and will be scratched. They come packed face to face so only the raised seams will touch the panel and that part has a plastic cover. Even if I took up a few, I would have to man handle them on the roof to spread them out. They...

    general truss design question

    I agree ... I actually got up thinking about this (again ... and again ...) I was thinking I have some left over 2 x 4's that are 16 ft long. Maybe split them into 2 x 2's and the webs into 1 x 2's Or even use some left over osb split into 2" strips for the web pieces. I don't want a solid...

    general truss design question

    Thanks ... There is obviously a lot more options In the long run, it is such a small load that it may not matter but I may as well build it as strong as possible. When you are working by yourself, there is just no easy way. Even getting a crane and lifting the crate onto the roof would not...

    general truss design question

    OK ... here is a dumb one. I need a temporary slide. I need to get 96 pieces of metal roofing ... 16" wide x 38 ft long ... to a roof. The edge of the roof is about 18 ft off the round. The metal is super flexible ... if it bends, it is garbage ... If you hold one end straight up, the other...

    min NiMH charge voltage and extra parts

    OK ... I was given the job of duplicating a "simple" box that monitors air flow in a duct. Seemed simple ... I dabble in electronics (I design and build industrial control panels .. starts ...plc's ... HMI ....) I knew the guy who designed and built the originals about 25 or 30 years ago ...

    coil winding help please

    Just an update ... I finally got around to winding the new coils. All my tools are in storage while I build the new workshop so I had to do with what was around the house. I bought a cheap counter to keep track of the winds. In the end, it came out perfect. Almost identical to the original...

    Correct torque for grade A rod ?

    I was just clamping a pressure treated 2 x 6 to a concrete pad ... nothing fancy. And you are right ... even at 25 ft lb (at least that is what my cheap Harbor Freight torque wrench was set at) the washer (I used a slightly larger 1 1/2" flat with a lock washer on top) is pulling into the wood...

    Grade A threaded rod torque ?

    Awesome guys! Thanks for the link. This is probably over kill for a small shed but I figure better safe then sorry. Thanks so much again ! Mike

    Grade A threaded rod torque ?

    I am realizing exactly that. Went back tonight and checked the torque ... almost every one needed a bit more to tighten. I can just imagine over time as the wood dries and shrinks what will happen. Makes me wonder why they use this method to hold down a house. Mike

    Correct torque for grade A rod ?

    Just tried 5 ... they all held. I realized that it might be pointless finding a value ... I am using a Harbor Freight torque wrench .. probably off by 100% I set a 3/8 drive to 25 ft lbs .... I think I am double that. The washer pulled into the 2 x 6 before it "clicked". I am using lock...

    Grade A threaded rod torque ?

    Long story but we are using these to hold down a shed to a pad (watched a neighbors fly away in a wind gust). Very small shed ... just didn't want the wind to take it. We epoxied a bunch of these into the concrete pad. I was just afraid of breaking or stripping them. Just looking for a value...

    Correct torque for grade A rod ?

    Hello, I posted this in the structural area but maybe it is more correctly a mechanical question so I am posting here also. I have looked all over the web for a chart showing the correct torque for nuts on a threaded rod. Found lots of charts but values all over the place. The issue might be...

    Grade A threaded rod torque ?

    Hello, I have looked all over the web for a chart showing the correct torque for nuts on a threaded rod. Found lots of charts but values all over the place. The issue might be the material. The threaded rod is 1/2"-13 hot dip galvanized grade A So, this is the lowest strength rod...

    why would there be a max depth for an epoxy anchor ?

    Thanks guys! To my surprise, the engineer who wrote me earlier today got back to me after hours tonight (now that is good customer service). He said that with this product .... " You can put them in deeper, just won’t have any additional rated capacity." The testing report / specifications...

    why would there be a max depth for an epoxy anchor ?

    Sorry, started a new thread as this is a bit of different question. So, it is too cold to use Dewalt (Power Fasteners) Pure110+ (min temp 41 ... we have snow on the mountain behind me). I wrote and they recommended AC100+ Gold as it can be used down to 14 deg. So I was reading the spec sheet...

    Threaded Rod anchoring help please

    Thanks! I sent an e-mail to the company .... The Pure110+ that I have used before does have a lower limit of 41 deg F The AC100 and AC200 both have lower limits of 14 deg F and will work fine. The AC200 I was told is a bit stronger and used more for rebar applications. The AC100 is on par...

    coil winding help please

    Thanks! I did measure the wire with a micrometer and based on that and on the resistance, I was determined it is #37 magnetic wire. I bought a roll ... 2000 ft for $15 ... cheap ... I only need 200 ft so I can try this a few times if need be. I am going to "cheat" a bit. I am leaving a...
