I’ve been a carpenter for 25 years. These days, it’s all speed. Rarely will you find a boss willing to pay the extra $2.00 to gain a higher level of professionalism. Most people are just hacking away at warp speed to make that dollar. It’s refreshing to see a carpenter with pride. Thank you

Its the little bits of advice like this that make a difference. Im doing my own loft conversion, as a sparky im naive when it comes to wood. I've learnt the hard way in regards to regularity of timber. Some of them were over 5mm out!. Looks like il be getting the electric planer out as they're all installed now. Great vid.

Great video, thank you Robin. This stuff is simply invaluable for DIYer's like myself.

[@toobad9946]

While this is obviously a lot of extra effort and very time consuming it is a sound process. It will also help to take this step so that you can completely discard the few pieces that are actually unusable. A few bad boards always manage to sneak into the stack. They can (almost) always be used for blocking. This may seem like it's overkill but if you are building a deck with a large surface area, the finished product will be much more impressive. Thanks to the channel for demonstrating the power of craftsmanship!

[@mattcartwright8272]

Great tip - I would always make sure my joists were crown up but I never thought to check the relative dimension to one another. Mind you, I often had milled my own timber so they were all the real dim e.g. 100x50 (4"x2"). Used to pee me off no end receiving an order that was not even close to the dims I wanted/asked for. Never understood why they just couldn't do it at the 'proper' dimensions.

Really great tips Robin and the 6 P's coming into play again.

[@incidentshappen]

Hey Robin, I'm a US Architect and i have to say ... this is incredible because I'd wager that floor won't creak. Typical construction when they put the sub floor down they would use some liquid nails to adhere along with the physical nails - but those 1/16-1/4 variations between joists would create high and low spots meaning you'd be relying on the adhesive to take that up. Taking those variations out means the subfloor will be resting fully on every joist. Great!!

[@AndrewSmith-bb8sh]

God damn it Robin, someone just like me. When I was working in carpentry I always tried to strive for perfection, but others used to think I was being crazy. One of the reasons why I don’t do it anymore. Just wish I could have worked with you. You are the master. Keep up the amazing work!

[@step0601]

I second a previous comment, it's all about get it done as quick as possible. I at least try to make sure any bowing is facing up but the guy I do most of my work for would be doing his nut if he caught me doing this. I had to stay away from a job during lock down and when I returned the governor had fitted the joists in a loft conversion, they were so bad you could feel the up and down as you walked across the floor. I swear I could write a book on having to deal with bodged work while I'm not there to oversee it. And you have to try to make it good without upsetting whoever cocked it up! A great method though, I'll try it out when no one's around!

[@albertbatfinder5240]

Brilliant tip. Any time you lose in shuffling the joists can be made up by fast-forwarding the rest of the job!

[@SandBoxJohn]

Across the pond common practice with dimensional lumber is put in all of the joists crown edge up. If one or more joists are standing proud of the others use a power plane to bring them down to the others.

[@ThePhil543]

Same here, The problem as always is money, unless you have high end clients you wont get paid for this, In fact it will cost you money

[@SandBoxJohn]

@@ThePhil543 If your clients are high end you will likely be using engineered lumber (I-joist, LVL) in place of dimensional lumber eliminating the need to make use of a power plane.

[@ThePhil543]

@@SandBoxJohn Not quite the same here in UK , All timber comes Reguarlised for size, The only difference is structural grading for strength. also timber merchants store it outside so your at the mercy of the weather. When you order they will deliver it as is , You can accept it or send it back, it all costs time and money

[@fishandgameman]

It won’t matter inside of 15 years anyway. Untreated lumber over the crawl space, sans a vapor/moisture barrier, won’t be much left if any heat is ever added to the building. I would suspect wood eating insects might have field day also being so close to grade. Maybe they still use Chlordane over there.

Hi Robin - presently working under my house here in Oz - worked in the UK for years and except every country has it's own ways due to environmental and exsisting building constraints. On a personal preference I enjoy being able to have enough room under the house to inspect / run new services / make repairs and keep out pests, we also don't have snow here so air flowing under the house keeps homes cooler. Enjoy your show and picking up new tips - cheers Sean.

[@ukconstruction]

HI Sean, we have rules that limit the height of a building that is built under permitted development and this only lets us build to 4m high from ground, so for this we have to keep our margins tight!!! I like your suggestion and the practicality of that, do you get snakes!!!!!

[@rickmcroberts9101]

Quality control standards related to lumber size specifications has fallen to the wayside nowadays. Go to Home Depot & try finding 20- 16 ft 2"× 10"'s that all measure the same width. Fact of the matter is that from one end to another & between those boards widths variances can range from 9 11/32" to 9 21/32"! In todays world you must adjust the elevation of each & every joist hanger accordingly relative to the variances that do exist among those boards allegedly "standardized" size range. Unfortunately assuring the joists are crowned similarly let alone sorting them accordingly is a lost cause if you place them in prehung joist hangers which have all been set in a standardized position. This video demonstrates a level of craftsmanship I admire & practice. It's a shame that a respect for such quality is being lost in so many areas of life today. You'd think those who sell lumber would assure it was milled with even half as much care as the craftsmen put into the quality of what is being built with that wood in this video.

[@chrisford8403]

Just throwing this out there. SOMETIMES, why you don't see large crews doing this stuff is because the B team comes in afterwards and does it for the framers before drywallers get there. Mind you, I'm speaking of walls and ceilings. Depending on the type of subfloor, the B team or flooring installers MAY sand down SOME bumps. B team is only a name and not indicative of skill or training. In the N.E. U.S. flooring joists are usually slammed in crown up and then planed on the high spots. Last few floors I built were with "enginerded" I joists and 3/4" OSB subflooring and they came out straight and true with minimal effort. Well worth the cost of the products.

Great tip

[@EngineerMikeF]

In 40 years of engineering wood framed buildings I've never seen sorting by "crown", great idea for quality

[@ukconstruction]

Thanks Mike

[@MrTrda]

Really??? I was taught to crown my studs first day on the job. It’s a very common practice. Like brushing your teeth in the morning common.

[@EngineerMikeF]

@@MrTrda I've seen two practices. First, roll what you have how it comes off the lumber unit and reject anything that's giving you grief. Second, check & lay all joists crown up, as they come off the unit, reject the ridiculous stuff, which is a considerably better practice. In my experience (California) its about 50-50 as a lot of guys don't have a clue and a bunch more don't care. Robin's method is superior, tho more time consuming. Two things I'd do if I was framing- construction adhesive on all joists/trusses & use screws for floor & roof decks w/a screw shank design to suck plywood tight to joists; that gives a lot more force on the joists as they dry to keep them from going wild. I met one contractor years ago that ordered kiln dried (S4S) studs for a really tall wall on a commercial bldg; he said one call back on that type of wall would pay for 10 projects differential in material cost, and I believe that. Personally I'm a fan of I-joists for superiority in deflection over solid sawn, and utter uniformity in all dimensions (also easier for wiring & plumbing fwiw)

[@MrTrda]

EngineerMike F - agreed with the adhesive - I’m even putting adhesive on my studs/rafters before I drywall - big difference

[@EngineerMikeF]

@@MrTrda I've seen the best quality builders putting a dab of adhesive in the joist hanger saddle; it may not adhere (oil & dirt on JH metal surface) but it will make a good contact patch & likely obviate squeaks

[@amarjitbhogal4250]

What grade of wood is used for the joist and side's.

[@TurinTuramber]

Another method is ideally have extra joists so you can avoid the rough joists. Just cut them up and use for noggins or blocking.

[@ukconstruction]

Great point!, always order a few more this is a really good suggestion nice one mate

[@chrisford8403]

Check with you supplier first! We usually order extra lumber and several of the yards we work with pick up the left overs; they factor this in and expect it, especially when dealing with lumber over 16 feet. Only once did I have a lumber yard want to charge me for picking up the extras. Also, treat the yard guys well and they will take care of you. The yard guys are the people that set the lumber yards over and above the big box stores, in my opinion.

[@firsteerr]

this is very old school the sort of thing a real craftsman does or did back int he day and thank fully robin is not only carrying it on and forward but teaching others these days (as i have seen ) too many new builds involve poorly trained or uninterested "carpenters" who just throw the joists in as they come the simple act of checking the crown can make one heel of a difference , sadly not even that most of the time and new builds are plagued by squeaky uneven floors

[@douglasyoung9320]

You guys are working that dude that is packing those joist to death.

[@paultaylor6053]

In some circumstances when a floor is "loaded" with furniture etc those imperfections can often disappear ,so an up bowed joist can be put second or third in from the wall depending where heavy furniture may land , this can have the effect of "leveling" the joists and floor , of course this will work if you know what furniture etc is gong where , I for example have heavy oak french furniture and when I replaced all the joists in my house I put the joist that were bowed up in position under the large buffets etc this levelled the floor perfectly ,on another occasion in another property for a client I laid the joists "dead" level ,only for them to come back to me to say "hey our floor sags " of course I went to inspect and found they had loaded the floor with furniture in such a way that the weight placed on a particular joist did indeed cause it to deform ,that same furniture had been loaded with easily half a ton of paper items and other belongings , so I pointed out that flooring has deflex and inflex etc and the load ratings , of course this did not wash and even though I showed them a better solution to their interior design choice , no they wanted what they wanted ,a level floor , and so I made one final attempt to help them understand the limitations of floor joists and floor covering by repositioning the furniture on the opposite wall ,and of course the same effect ,then I showed them that choosing the other walls which meant he load was spread across all the joists thus no "sagging" but again "no" that idea conflicted with their "feng shui feelings" and finally to accommodate as we Carpenters will often do I opened up the floor and place a trimmer joist to "up lift " the furniture , of course as you might imagine financial negotiations sagged as much as the joists ,and so I charged for the additional materials and labour but charged nothing for the afternoon and back breaking labour moving their furniture around etc etc , had I know what they had intended to place on the floor structure before hand I would have found that " joist with the hump and installed it or used a trimmer or maybe even a steel , the lifestyle of the couple in question really warranted a concrete floor but they lived on the second floor , thereafter the neighbours below contacted me to come and see what could be done for them as their ceiling covering was forever cracking , I installed a dropped ceiling with 300mm ecoustic insulation ,funny ,how level joists and poor interior design choices can be the cause for so much fun ! , bloody french !

@@safcforme3475 Doesn't have to be heat. We cover our lumber to protect it from the sun, not so much rain or snow; it will cause uneven drying and warping. Also, keep in mind that it can take a month or more of framing before a roof or wall sheathing goes on. In that time, rain and sunshine can cause some serious warping. I've seen several decks were 4x6 PT posts are warping; we switched from 4x4 for this reason and it seems like we'll need to go to a 6x6 to prevent it.

[@ryanwright2981]

What hangars are you using Robin? It looked like you block planed a face on one of the joists to get it to fit. The finish dimension of the regularised timber usually leaves the joist fitting sloppily in a 50mm hangar. I've resorted to adding plywood packers before to take up the slack. Would be great to find a hangar that doesn't need any more faff, over what already needs dealing with like mismatched "regularised" dimensions. Great vid. Love watching your work 👍

[@maclagor]

Out of interest, when you say 'dead flat' Robin, what do you mean? What sort of tolerance is that for you? 0.5mm? 1mm? I ask as it seems to be quite relative - certainly in 1st / 2nd fix carpentry 'flat' and 'square' seem to have wild variations...

[@ukconstruction]

well we like to minimise the tolerance so we shuffle to get the pack of joists smooth but we also use a dry graded treated timber so all the movement has happened before we fit, we would look for a tolerance of about plus or minus 3mm over a floor like this

[@ixurlife8062]

And that's how to do it properly for all the cowboys out there 😎😁

[@matthewcalder4351]

Is this what they refer to as "cups and crowns?" I could watch your videos all day Robin! Absolutely love it. 👍

[@UberAlphaSirus]

Cups and crowns are more a joinery thing. But using the bow up (crown) will flatten out more once a load is on it. where as bow down (Cup) will just get worse with load on it (cup and crown isn't the correct term for londitudinal bends mind). But in joinery, I am presuming your from over the pond. In the UK it would be smiles and frowns (bark side and wood side) alternating, when you make, say, a solid tabletop out of individual boards, So humidity changes even out the expansion, so it doesn't go wildly cupped or crowned, it makes it wiggle, so overal remains flat.

[@thetessellater9163]

Cupping and crowning refers to the shape when laid flat across its width rather than vertical as here. Inevitable really, given flat sawn timber comes from round trees!

[@tomsmith9048]

It depends what part of the world your from in the UK and Ireland its commonly known as checking the camber hope this helps 🔨

[@francisling3196]

How's the best way to ventilate that floor?

[@ukconstruction]

Hi Francis, I use a plastic plywood fascia that is spaced off the ring beam by 10mm this has a ventstrip on the top that also provides a kicker for the cladding and allows air behind the cladding and under the joists, we run this allround the full perimeter, the plastic plywood is taken beneath the ground and a concrete fillet is laid to prevent rodents and other wildlife from getting under the floor

[@basshead8914]

The time taken to do that compared to cutting blocks and having them installed at the plywood joint would be so much more efficient let alone stronger to boot....

[@user-xv5iw5zh4m]

If the soil freezes and expands (especially clay soils) it will lift the building - that's why you leave a gap beneath the building when you build on piles/piers
