Man, that just looks like one bone gnawing, jaw grinding project (the beam that is).
I saw in one of your previous pics that you had some temporary supports in place for the joists, but they're missing now on one side. Is it safe to assume that you're planning on re-installing those before cutting joists?

The jack posts will be secured to the beam with some (wood) lag bolts perhaps? They would be secured into the packed wood since I can't exactly use a nut on the other side any more. I just have to drill a few holes, which is not so bad with a decent bit. I could also weld them in about 1/2 the time. I do have a welder. For some reason I would want them removable. Is that dumb? I mean, you could easily grind off the welds.

Those jacks in the pic are the "temporary" type, so I have not attached them. I have two of the "permanent" type ready to go, but they don't adjust in length -- so will go up only when I get the beam in its final position.

I do have hearing protection and will use it for the nailer...along with eye protection. "Everybody put their Mickey Mouse ears on!" Thanks!

Fotto: I do have the temp walls on both sides of the beam still. You can see them just at the left edge of the pic. I wouldn't want to cut the joists without the temp walls!

Received my Green Glue, clips, DC-04s, Silenseal and a couple of other sound isolation supplies courtesy of the SoundProofing Company! Just in time...ok, well quite a bit earlier than I need, but it won't hold me up at all.

It's always fun to receive something in the mail.

I know right? Why is it so fun getting something in the mail? Even if its just something stupid...its still exciting...or maybe I'm just easily amused.

Cutting through the joists this way is tough work. (Sawsall with tight clearances) I wish I had come up with an easier method! I'm hoping to get this beam finished today and my arms/shoulders are already tired....

I have to go to HD to get some more Sawsall blades. I'm hoping that will make it at least 5 times easier...I hope.

I finally did some tweaking with my THT and Crown XTI amp. Apparently I didn't have the amp bridged. Now I know what the driver sounds like when it bottoms out even with the sub channel turned all the way down on the receiver side. Turned back just a bit and HOLY CRAP that is a lot of LFE. I haven't watched a few popular scenes for LFE since my new AVR. The WOtW lightning scene makes me want to run and hide and it's not even at max.

Do I really need a rotary?

hehehehehe! That story makes me giggle. I really want to build mine! Maybe ill sneak in the lumber i need for it when i go get my floor for the riser! Ill have to figure up again how much i need...it seems like it was only two sheets to build it.

What kind of question is that

Of course you don't NEED one, but you really SHOULD have one Especially since I am waiting for the build. Now that you said something you must build it!!

I think the easiest method is to cut them from above with a worm drive circular saw....

That would be the easiest way if you discount the part where you have to rip up your floor

You know in DIY one small project always leads to 5 or 6 more.

PT: 2 sheets of 4x8 should do it. I only used two tubes of PL adhesive, but there are others who used something crazy like 8 of them! WAY overboard....

Beemer: Ha ha! I plan on doing/trying the rotary even if it is not needed. I might have to tell my wife that I'm doing something else though. Making a toy for the baby??

Well, new blades made the job about 10 times easier. I have 11 of the 13 joists cut. I left the two that the winches are attached to. That way I can rest and think out how I want to approach them. The winches are still a failsafe support, but I also have 2x8s under the beam along with the jacks.

All the joists are cut. I would just crank that beam up there, but now I have cut about 50-100 nails that are sticking out from the subfloor. I need to give the shoulders a rest. Damn.

I'm looking forward to trying out that palm nailer. It should be fun for about 10 nails and then it will be work again. Ha ha!

I pretty much have it up, but there is some wiring in the way that I'll have to move. I wanted to see if I would clear it, but doesn't look like it. I didn't get to the joist hangers, but still happy with the progress.

The new beam is 8.5" tall and the old beam is 8" tall. To the bottom of the joists is about 6'11", but the joists are only 7.5" tall, so the beam actually hangs down about an inch below the joists. I still gained 7" of height which is a lot when you are comparing 6'10" and 6'3" before floor or ceiling.

Definitely worth it. Those are some critical inches to be sure!

I have to keep telling myself it is worth it! It is only $1000 and 8 days time for a $10k(?) and 6 month(?) project.

Beam is all the way up! I still have joists to hang. I tested my palm nailer and it drives a nail in about 1 second! Hopefully that means it won't take too long to do the joists. I also have to secure the permanent posts. They are in, but without the bolts that prevent you from kicking the posts out from under the beam....not that you can as there is a lot of weight on the posts.

I will be even more excited when I can start framing! Isn't that were most people *start*?? Lucky!

So, I go to HD to pick up lagbolts and Tapcons. I drill a hole in the concrete for the tapcon with the bit that comes with it. I use a hex driver on the drill in hammer mode as the instructions recommend, I get half way in and.....the tapcon breaks. What the...?

I'll try another one, but come on!

Ted: the beam, the framing or the Tapcon?

Ok, so I'm 0 for 2 with Tapcons. I'm going to do a search see how to avoid this.

blow or vacuum out the holes before driving your tapcon in and you'll have better results.

Thanks Ted! Can't wait to start using the Green Glue you've sent.

Vcook: I was born in Chicago. Yes, I blew out the holes and used a shorter tapcon and it was no problem at all.

Now I need to drill into the beam and install the lag bolts before hanging the joists. I think this took about 3 times longer than I thought...which is about how most things go anyway.

Man, looking at that beam, I almost feel bad lounging around my hotel room this weekend.... (in Israel the weekned starts on Friday).

That is truly a huge acomplishment! Nobody got killed and your house is still standing, can't ask for more than that

Nice job! Now get working on my, I mean your, rotary sub!? I'm dying here!!

Thanks Beemer! I have my share of lounging moments too. No rotary until it's time!

I have the posts all nicely secured except the hole for the lag bolts on the top of the posts are positioned just perfectly such that they are between the two 2x8s packing the I beam. Most of them are spinning around freely, so I'll have to get some sort of expanding bolt. Another trip to HD! Woo hoo!

...but I'm going forward with the joist hanging anyway. The posts are not going anywhere. This nailer is the isht! I'm jacking up each joist a small amount before attaching its hanger. I figure the beam will take the weight of joist before it sags too much. It's probably less than 3/32" per joist, but what the heck.

Have fun with the palm nailer! Too bad about the bolts spinning, that is annoying.. At that point I would pull out your welder.

Probably a good idea with joists, just don't over jack them.

Beemer: I spent the effort to drill the holes, and I'm going to use them, dammit! Making 8 holes straight up through 5/8" of steel is not that fun.

I'm just jacking the joists up a bit. I can see if they are slightly sagging compared with the subfloor above.

The nailer is fun, fun fun. I'm 1/4 done and then I can start removing the temp wall.

Ben: Thanks! Looks like a hell hole in basement in real life, but it's getting closer.

I feel your pain! Drilling up over your head is not fun in anything, much less 5/8" steel.

I don't know if you've come up with anything yet, but one option might be to use threaded rod and some sort of epoxy. Just wait for it to dry and put some nuts/washers on the bottom.

That might be a mess though, if the epoxy is runny at all..

You could also drill a hole perpendicular across each vertical hole ( in the 2x8) and use threaded rod with a nut top and bottom.
