To modify Joists without engineer stamp or not

Looking to build my forever simulator. Have an eye XO unit with performance package that worked perfectly in my duplex garage. Fast forward to today and we bought a house I was planning on putting a Sim in the basement. Problem is bottom joists are 7 ft 9 inch. I got a friend's dad to engineer a drawing to see what cutting 3 joists to create a 2ftx5ft or so hitting box to allow Rightys to fully swing driver. This would give around 8 ft 6 inch which is perfect for my height (5'8) flatter swing.

The drawings are good, essentially sistering two 2x10s to each side of the surrounding joists ( so 2 joists will get 2 2x10s on each side) up to the load barring area. Essentially id cut joists 3-5 down, and 2/6 would be reinforced. The 3 joists cut would be supported by temp posts and the swing box would be secured perpendicular with 3 2x10s. So the box would be surrounded by 3 walls of 2x10s. Then alot alot alot of heavy duty hangers

So most contractors want a engineering stamp and my buddy's dad essentially said he wont do that. I can go to a firm and get it stamped for around 2-3k and then permits (what that costs), but essentially I am wondering if it's even worth it going down that route? We are having a baby and we dont plan to move for a very long time. I've seen other redditors do a similar renovation so wondering if anyone else can chime in on what they did? We are weighting the pros and cons and trying to determine if that extra 3-5k of hassle is worth it.....

Tldr: joists modification without an engineering stamp for golf simulator swing box. Do I really need it if I dont plan on selling? Will this cause huge structural damage?

Photo 1 is my roof, 2 is the drawing, 3 is ideally what we'd like to build.

Thanks in advance.

Geodesic dome

This is considered a timber frame, right? I've been collecting the wood from scratch. Here's how i'm putting it together by myself on a solo build.

Pre-assembly of Bents a bad idea?

Hi folks - Im building my first timber frame and things are progressing along and Im close to finishing the joinery for the first bent. My initial plan had been to cut all of the pieces and then on assembly day put them all together as I think is common. What Im wondering though is if its a bad idea to assemble the bents as I build them. And by assemble I mean peg them into a complete bent.

Im still working out my work flow - I think ideally it would be easier to cut all the posts at once, all the tie beams at once, etc but since this is my first build I wanted to do a complete bent first to make sure my joinery was working and that my measurements were OK. The problem Im running into is storage space - I have limited room to store the cut beams and since Im doing a test fitting anyway as I cut the joinery for a bent - could I not just pin all the sections and let that bent sit as a completed unit? Then do the next two in the same fashion? Then all I would need to do on raising day is attach the door posts and the girts. My point is that I dont have room to store the cut beams inside so is there any reason not to just complete the bent and store it assembled outside?

I know that this is likely uncommon due to the space required to store an assembled bent - but in my case I can assemble it then just pick it up with the tractor forks and stack it over by where the raising will happen later on.

So is this a bad idea? My guess is that I might run into some issue with fitting the bent into the post brackets on the bottom. Maybe this is something that's easier to attach at the base and then pull the joinery together at the top?

How would I?

I’m designing a frame for a sauna, posts are going to be mounted on concrete feet but I’d also like to do a deck that sticks out the front abit and a step, how would I go about doing this? I could do little beams coming out of the cross piece like this sketch jointed with dovetail or m+t. Or half lap but maybe that would compromise the structure
Apologies for the terrible drawings

White pine discoloration

I know I’ve asked before - but I was hoping some other folks could chime in if I’m doing something wrong here. I’m struggling with keeping milled fresh pine from discoloring. But after some reading I think I’m dealing with two different things. One I can likely do something about and one I can’t. If you look at the pictures attached I think the one with splotchy blue stains is mold - I don’t know why I keep getting it. This beam is stored in an open barn - lots of air - and I sprayed the beam with a borax solution as well. This is the discoloring I’m struggling with. The other two picture seem to be in the grain and I believe is possibly the sap wood just changing color. I don’t mind this and am guessing there’s not much I can do about it.

Am I reading this right? Anything else I can do about boards that are molding as is the first picture?
