Re: What size beam . . .

I would not dare use that setup that you posted myself QC, it looks like a death trap, or injury waiting to happen. Just my 2 cents. If I remember right you said you have a hoist in mind to use for the job or future jobs, that would be the way to go in my opinion. Although I would like to know how much that boat weighs that is hanging on that death trap. The ratchet straps would not be as nice and easy to use as the hoist would be, then you got to release the darn ratchet straps with that much weight on it hmmm, not this man. Of coarse that looks like it would sway pretty easy on that setup. I like the boat better then the setup it's hanging on. It's to bad that you are picture challenged QC some pictures of the area in subject would be nice. One thing I liked when I worked at Tyson foods as a lead they had an electric hoist to swap the electric jack batteries and pick up forklift parts when in repair the whole setup was very nice, similar to my uncles setup (minus the electric hoist) I mentioned earlier. The reason I say an I beam would be my second choice because cost may be a little more and it may be a little overkill, witch I think overkill can be alright in these situations for safety issues.

Re: What size beam . . .

I can post some pics of the garage, but I am traveling now and won't be home until late Thursday. I can always upload them to iboats. I just din't wan to fart around with photobucket when I have my own site. Stupid, honkin', Time Warner has had a "problem with the server" for three weeks now. No ability to publish to my personal webpage until they fix it. I am P.O.'d Grrrr . . .

Thanks for the thoughts, exactly what I am looking for. The mega header in the center of my garage has to be good for something, it is massive and on 6 x 6's or bigger . . . I'll have pics on Friday.

Re: What size beam . . .

OK, I have attached some pics below. First one is the header that is in the middle of the garage. Second one is the span from the header to the front of the garage and the "front" header. The third one is the span from middle header to the "back" of the garage. This could be an issue as it is actually boxing in HVAC stuff, so it is not a header. At this point figure that I find a away to tie the "beam" into whatever support I can find across the rear span. I may also tie the spans into the joists above for additional support. With the header as the central strength I feel OK. I can also center the load(s) towards the header on either side.

I may actually cave into using a "cherry picker" for the engine, and only use this "span plan" for turning the hull over. That would mean max of around 600 lbs. on each hoist . . .

Edit: Oh forgot final dimension info. Height to the ceiling is 9'4" on both sides of the header. Height to the bottom of my storage shelves is 7'7" (Boat beam is 6'7" max. with a strong taper toward bow and stern). The front span is still 9' and the rear span is only 6'4" . . .

Re: What size beam . . .

OK (as I'm sitting here scratching my head literally). I'm put this all together. On the first picture you have a perfect spot if you welded a plate to the end of a 2x3 square tubing or I beam then bolted it up to her, I know you said that is in the middle of the garage. Is the opposite side at the back of the garage similar? I'm going to half to study it a little more seriously. You wouldn't want to mess with the front of the garage I wouldn't think. The back yes you have problems there with the above storage. I'm not as confused as I first was lol, . I got it figured out on the locations of the pictures. I'm just running a little slow today.

Bump for some more input also, knock knock guys .

QC- You should have no problems from what I'm seeing. I'd think that with some 3X3 heavy wall square or 3" sced 40 pipe with flanges (3/8" plate about 8X12) on the ends and use 8 lag bolts (maybe 7/16 or 1/2 by 2 1/2 or 3) will be great. From this add the pulleys or eye bolts for your chain fall/comealong/winch. For lots of things we rednecks (and wannabe rednecks) WAY over engineer to be on the safe side. If a 2X6 is good enough then we'll use a sistered 2X8 "just to be safe". My garage was built that way and so is my house. I kinda got stupid with some of the things in the house but I wanted it to last and be strong. You could use my porch/deck to drive on if you wanted. Way overkill. You know what? I like it. It added about a thousand to the overall price but it ain't going anywhere.

Maybe this diagram will help. Don't worry about anything on the single car side of the garage as that's my work"shop" area and family work"out" area (we just buy workout stuff, we don't use it) . . .

Re: What size beam . . .

I agree with Kenneth Brown, take whatever size beam you would like to use 2x3, 3x3 or I beam in heavy stock. Weld a plate to each of the ends of it bolt it up with lag bolts, I know you'll need 2 beams. You would half to use the front I miss read that earlier the back section is only 6' 4" wide. I was studying on people adding a hoist beam into there garage last night unfortunately nobody showed pictured of anything similar to yours garage layout or similar to what we are talking about. One guy had a wood framed roof, with his hoist hanging from a 2x6, but said he is going to change it to a roll around hoist (like I talked about my uncle having). I was just trying to find a picture of somebodies setup to pass on to you.

Re: What size beam (Update. Success & pics)

OK, so after taking your advice (s) here, I poked around some more literally. I made an outline of the boat on my garage floor and figured out where I need the two hoists. I decided to take a look under the drywall ceiling at both of those points. Voila!!!! 2 x 8 Joists magically running on both sides of my two points, and . . . I could reach into and on top of them fairly easily through reasonably small holes. So I double checked and they are on top of the "Mega" header and extend to two headers on both sides too. My luck on this is amazing. Typically when I try and find a stud, I miss, and when I am trying to miss a stud I hit them. This time both points were precisely in the middle of these joists . . . I headed down to Lowe's for some chain etc. Ended up with two 4 foot pieces of angle iron to lay across the 2 foot joist spacing. 1/4" thickness by 2". The first task is to get the engine into my garage, so I stacked 2 pieces of angle iron on top of each other for double strength. Laid them on top a pair of joist hanger type things (only to give them something solid to sit on instead of the edges of the angle iron laid flat on top of the joists (looks like a chevron when end viewed pointing up) . . . For good measure I threw an inboard propshaft under them too, fit perfectly.

Finished hoist install

I had to pick up the engine yesterday, and get it out of the truck bed.

Moment of truth . . .

Ahhhhhhhhhhh!!!!!!

Success. I made this dolly and set it up to approximate the stringers so I could get my mount measurements correct before the next time I have this engine up in the air . . .

Thanks for the ideas, next part is flipping the hull. For that I bought two big tow straps with ratchets. I am going to run a piece of round pipe between the two hoist hooks about 8 feet apart. The slings are going over the pipe just out side the hoist hooks. and I am going to roll her over inside of the straps with the pipe helping the straps "roll". Found a guy who did just this. Worked well for him . . .

Good job QC. Should turn out to be a nice boat!

I'm going to pull a merc 2.5 a friend gave me out this afternoon. I needed to cantilever a beam across my shed so this thread came in handy!

Re: What size beam (Update. Success & pics)

Well QC at least you have that part of the battle whooped. Of course I don't half to mention but will mention, be safe always keep safety in mind, don't get to aggressive when hoisting the boat or anything else for that mater when it comes time to tackle it. Aint nothing like having something heavy crashing to the ground, just ask my father who had his little toe amputated. I'm not suggesting that the beam will give I'm just saying play it safe. Safety is mostly what I looked for during my last job I had.

Re: What size beam (Update. Success & pics)

FWIW, I noodled on this for over three weeks. The 2 x 8s were a godsend and the fact that they are only two feet apart is/was comforting. When it came down to doing the first lift, it was kinda cool that the engine was in in a pick-up bed with springs/shocks. As I put more and more load on the hoist, the bed would rise a little. This gave me a chance to hop into the bed, take a look at the joists, angle iron, hooks, chain etc. etc. while the load increased incrementally. I was one paranoid mofo . . . Also, I was able to let it hang over the blocks I had in the bed for a few minutes while I did another round of checks before I drove the truck out from underneath it all

The pics look like I was standing right next to it, but I was keeping my distance by standing as far away as the chain control would let me. My biggest concern was the cheapo load leveler, but it did fine. As I was going down the hoist would "chunk" ever so slightly every once in a while as the chain links rolled over the "sprocket" thingy. Everytime the whole load would quiver and "bounce" slightly on the chain. Those moments were nerve wracking!! At no time did the ceiling creak or groan or visibly flex, and I rechecked it a lot. This is by far the heaviest task, so I think I have made a decent test of the system, and I am going forward with the hull flip within a week. Thanks again for all of the comments and concerns, keeps me thinking and double checkin'. Good stuff!!!
