Super easy and nicely explained. If the length is 11ft and width is 11ft the height is 7ft. Is it going to be 6000+ US gallon tank? I need a tank size around 6100 gallons should i use the same formula as above?
@michaeldownes516
@michaeldownes516 Ай бұрын
Same formula.....that size tank filled to top would give you 6336 US liquid gallons.......815.4514 cubic feet will give you 6100 US liquid gallons. for an approximate result, multiply the cubic feet volume value by 7.48 to give US liquid gallons Formula is: Width X Length X Height= Volume, so, 11 feet x11feet x Height=815.4514 cubic feet (6100 US Liquid Gallons), so, 11x11=815.4514÷H. so, 121=815.4514÷H so, H=815.4514÷121, This Tanks Height to give 6100 US gallons=6.73 feet

Assuming the measurements are inchs....multiply 49"x19"x21" to give cubic inchs value for this this tank...next, because there are 231 cubic inches in a U.S. gallon, so next you will convert from cubic inches into US gallons, so divide your cubic inches value by 231 to give US gallon value for this tank. (if its an imperial gallon then divide your cubic inchs value by 277.42 cubic inches of water).

quick question, at 3:48 you set the triangle to 30 degrees. wide blade set 30 but narrow blade you highlight the top markings which say 50 ? Do you mean to use the bottom markings which say 30 ? thanks.
@michaeldownes516
@michaeldownes516 10 ай бұрын
...the 50 is the 250mm distance marked on the narrow blade.. .this is where you rotate until you get the angle marked on the wide blade for common rafter angles....but remember the actual angle of 30 degrees used in this example will be between the narrow blade and the red line (even though the 30 degree piont is alinged on the wide blade. ...If you are marking angles for hip rafter the pivot point is further along the narrow blade where you will see H/V stamped.....and you will then align the wide blade to the roof pitch (30 degrees) to the give you plumb and seat cut cuts for hip/valley.

Hi Michael, great video! I'm a bit confused on how we get the edge cut on the jack rafters. I am clear by what you mean to generate the seat cut. But, the edge cut doesn't make sense. Did you say the pitch of the main roof minus 19? So, that would mean, if the roof was 27 degrees pitch then the edge cut should be 8? Just doesn't seem to make sense with the roof I am working on now, 8 degrees seems far to small an angle. Any advice would be really appreciated! Cheers
@michaeldownes516
@michaeldownes516 Жыл бұрын
Hi Jack,glad you like the video, meant to say 90 degrees minus main roof pitch to set your skill saw agle at when cutting along the seat line to give the correct jack edge bevel. I inserted a note in to the video at 8.48 minutes making that point.

When setting out the hip for fascia and soffit do you always swing the hip closer to the crown rafter instead of the common side ? Another question when the hip needs to be planed do you just plane it unit it has the same upstand as the rafters is that correct
@michaeldownes516
@michaeldownes516 Жыл бұрын
Hi violet, you will find that the hip tail will swing more to the common side when the common side of roof has a lower pitch° than the crown. But if the crown has the lower pitch° then the hip tail will swing more towards the crown end of the roof. If you plane the common side until it matches commons up-stand you will have planed too much off...Instead....Mark the up-stand on the crown side of hip matching the crown up-stand.....the heel cut on BM will be cut at an angle to sit against the wall plate......cut it...place it in position keeping the crown rafter edge and hip edge lining up where they meet the the ridge... now observe the common side of hip....on this common side you will see the hip is above the common rafter edge slightly....this is the portion that needs to be planed off-square on this side of the hip. The top edge of the hip is now banked to match both roof surfaces.

Hello Micheal, at 16:15 is this where you get the plumb lines for both sides of the valley major and minor roof sides if so you mark it from your sheet of ply,
@michaeldownes516
@michaeldownes516 Жыл бұрын
Hi Violet, this is where you get the plumb cut for this valley rafter...you can scale down the roof to fit on your plywood sheet if its just angles you are after (angle wont change if you scale up or down)....if you want deductions add in the width and thickness of roof members at full size on to scaled down drawing of the roof. So, you now have scaled the minor and major runs etc to get it to fit on to your setting out sheet, but the width and thickness of the rafters, ridge board are added at their full sizes so as you can measure off their deductions.

....to get the rise distance from top of wall plate plane to where 2 thirds line of rafter meets rise line use the formula in this link kzbin.info/www/bejne/kIXIlGClhNdjhNU this will give you the «rise distance». In this video the word adjacent will represent common rafter run...and the word opposite will represent the rise distance. ...if you want rise distance to top of ridge board then continue with following..... .... place the common rafter plumb cut against ridge board...note where common rafter 2/3rd line meets side of ridge board..note distance from 2/3rd line to top of ridge board... ...now add this noted distance to the «rise distance» you calculated previously to give you total rise to top of your ridge board. Also, if you have rafters cut/marked. ...place pair of opposing rafters flat on the wall plates(WP) with their birds mouth (BM) heel cut in line with outside of Wall Plates ...use ridge board off cut to keep common plumb cuts right distance apart. ... Now spring builders line from one BM seat line to BM seat line on the opposite common. ..Now measure from builders line to ridge. As well as checking for ridge height the above outlined will also confirm if your plumb cuts are good etc. ...Also,its a good approach to confirm your rafters are set out correctly before you go on to cut the rest of the common rafters.

@michaeldownes516
@michaeldownes516 Жыл бұрын
If you go to 10.50 mins in to video and pause, you will see side view of both sets of jacks. ....ìn this example,the lower pitched jack is from the main side of the roof and so it has the same plumb cut as the common rafter on that side of the roof. ....The jacks on the hipped end in this example will have the same plumb cut as the crown rafter. Keep video paused at 10.50mins and note the following; ...the side view of the edge cut (end grain hatch/pattern) can be seen at this point of the video ...so to get the edge cut, draw side view of this edge cut on the side of your own jack. ...you now have 2 plumb lines on the side of your jack (one of these plumb lines now needs to be on the far side of your jack), ....so square one of those lines across the top edge of your jack to the far side, ...from where this line hits the far side of jack, draw a line back to top of other plumb line on near side of jack, ...this line you have just drawn on the top edge of you rafter is the jack edge bevel for this jack. same procedure as above for the other jack (for hiped end)...note its edge cut will be blunter compared to the other jack (main side) in this example.

Worth noting that regulations state that a sphere of 100mm should not fit between the spindles at any point. Whilst the sphere may not fit between the areas of the spindles that are not turned..the 100mm sphere might fit beetween the area that are turned. The sphere of 100mm represnts a babys head apparently....and the concern would be that the babys head might get jammed, or baby fall through the spindles.

It is worth adding that calculating the spacing between a moulded, or turned spindle will be different to the method described, because the 100 mm minimum spacing is measured where the moulding is at it's widest point, and not from the square stock at the ends.
