DIY FRESNEL LENS STAND HOW TO MAKE YOUR OWN STAND

hello there we are host and Rojas and today we're going to be taking a 2×4 and making a Pernell and stand like we use in all of our videos when you select the wood for a 2×4 you want to make sure that it's very straight and that it doesn't have any curves to it and you also want to choose a piece of wood that is heavy if you go to a home-improvement store 2×4 is very in weight I actually like the lighter ones better for the frames but for the stand you want one that's heavy what we're going to be doing is ripping the 2×4 and a half two by fours they're actually three and a half inches across so you want to set your guide to be one in three quarters but you have to accommodate for the width of the saw blade which takes about an eighth of an inch up so you want to set it for a little bit less than one and three quarters and then I'm going to show you a little trick where you nip the wood flip it over and you can see if you're right in the center if he did this correctly you should have these identical wit now so you should have something that looks just like that you're going to set your miter saw for a 45-degree cut you're going to place the wood I like to take the part that I cut and place it in word it doesn't really matter you can flip it the other way you want to cut it either the side that you rip or the opposite side you don't want to do it like this so in other words you don't want to do it to the thinner part I'm going to have the slightly longer paste so this should measure just short of 1 and 3/4 which it does now you want to take your miter saw and you want to cut do a 23 inch cut to the top not the bottom of this to the top so you want to measure to the very top on this particular ruler it has 23 and 25 that go across from each other so we want to go 23 and to the inside so it will actually be 25 mark but you want the peak to be 23 inches we're going to measure that your safety equipment on the piece should measure 23 inches and it does take the second leg and basically repeat the process use it you can use this one as a guide so what I like to do is take this and put it down in there just like that make sure these are the identical height just push it up against the blade hold the wood down with the saw without turning it on you now have one of each from different legs that are the identical size they're the same exact size now what you're going to do is flip this leg like that and now you're going to straighten your saw all right the next step is to set your saw to zero degrees you don't want any angle on this next cut and what you do is you take your wood which should have a cut like that now this is still the long piece so you can see that that's a long piece of wood that's left over from that since we already cut 45 once we're just going to reuse we're going to use this cut twice so you want to measure from this peak up here for the second cut 25 inches and then you want to we're going to come over here we're going to go from the 25 inch mark there's a reason why we do them at two different heights which you'll see in a little bit so you can see where it is it's a ruler so you now have a leg that looks like that and you have this long post here okay this piece we're going to put this off to the side we're going to do the same thing but we're going to do is we're going to use the secondary leg the one that hasn't been cut yet or the secondary stand piece and we're just going to take these and you can see what I'm going to do the best way to do it is to line the ends up like that so that way they're nice and flush to measure it you push it up against the saw blade hold it in place so we have the two different legs right here one of them has a is about two inches shorter you can see that like two inches shorter from top to bottom and you've got your legs set here this is going to be the stand pasta holds it in place so what we're going to do is you need a table for this that is perfectly has a nice perfect straight edge you also need this is a drywall ruler and basically any t-square you you need to make this square that's that's very important to do so what I usually do is I'll line this up to the table so that we know that we're set and then I attached just place the wood there so I know the woods exactly where it needs to be now what you do is you take your legs just like this since one's longer and one shorter they're going to end up in different places what you do is you use the base of the table as your guide and you put one leg to the very point there the other leg to the very point here this is a little tricky to do sometimes you want to make sure that they're nice and flush and that they match up there and there so you've got that done so now you can see these are two inches apart and that the reason that we leave this space is so I can drill a screw here on the second one to lock it into place if they were even the screws would all bang together and you'd have all of your screws right in the center instead you've got screws here and screws here and that's why that's the only reason because this is all square here it's going to be the exact perfect height now this needs to be square because if it's not this is going to be angled when it's up so now what you do is you take a pen and you mark there and you mark there and then you're pretty much set what I'm going to do is get this first one drilled you can see you want to go down about it you want to go as close to center as you can with this so just make it real easy mark it with your drill flip this up yourself a little pilot hole there so then this is going to go in real tight like that but we're going to take these and I've got a glued up put some extra glue on there we're going to go towards the edge of our table so I can reach it from over here we have a extended Phillips head bit on here and we're going to take a two and a half inch screw three inch will actually pop out the other side too so what you should have is something that looks like that now we're going to put some extra screws here and you can pretty much just pre-drill them dry them in you want this to be a sturdy as possible so we do this time as we drill right into the top of this and straight down about I don't know maybe an inch away just kill yourself a small pilot holders bit by the wings eight seven eight so I've got this nice and flush here nice and straight put a lot of pressure on you can see I'm squeezing the glue out of it make sure this this is even go ahead and sink it a little bit in there and there's your second leg alright so we've got this now what I'm going to do is show you how this looks this is the interesting part for the second side you line the wood up you take your short piece line it up there the long piece line it up with the other leg make sure that they're all the same you can actually you have wood plants it's a good idea to clamp these together so that way you can hold them in place do is you mark your wood here you mark it there since everything is identical these stands are going to be the same so we're going to put a little s there so we know that that's this one goes off to the side then you basically repeat that process so you can pretty much stop right here I've done plenty of stands that that alone holds it so if you don't have an extra piece of wood you don't have to do this but what I like doing is cutting another 45 they're lining this up and matching it as closely as possible down here and what this will do is this will keep these from pulling out from spreading apart so I'm going to go ahead and build these since this stands for some somebody I know measuring this can be kind of tricky so you can see that I'm going to show you what happened when I did this better to cut it a little bit longer you see there's a gap in there because if you go shorter you really can't deal with it now what I'm going to do is just trim this down a couple times until I close this gap here so you close the gap by cutting this just a little shorter checking it cutting it a little shorter checking it again they should be almost perfect I did everything right you should have this going these are almost practically identical in size and that's your stand right there this is about a little bit almost a foot tall so when your lenses on there it makes it a lot taller that's how you make two identical Pernell fans and you hold these up they are the same and they're perfectly they're not tilted or anything so your lens goes between these like this and bolts into place and then you can add a small metal bar there if you want
