    This was actually my first replica prop and was done back in 2012 on a very limited budget. At the time, I wanted to make a screen accurate NIKE FOOTWEAR bag, but due to the low budget, limited tools and build skills, it was more of an inspired version :cool

    The story from 2012...

    Last Friday [13th of April], I bought some large diameter PVC pipe for the case and today [15th of April] began shaping it. I used a 4" angle grinder fitted with a diamond cutoff wheel to cut the PVC pipe which has a wall thickness of approx 1/4". It cut OK, but I will have some sanding to do tomorrow as I did this by hand :unsure

    The real bag :love is 22" x 11 1/2".
    [​IMG]
    My choices in pipe were either 12" (pretty close) or 10". I elected to go with the 20" x 10" pipe so we will see where this goes. Whilst I have made some really neat stuff in the past, those projects involved outsourcing many parts (machining etc) and ended up costing thousands! I have no intention of spending that kind of money on this project. My "MAG" shoes cost about $65.00, so this project won't be that 'expensive' if I have my way :love

    This is DIY after all and whist DIY stands for Do It Yourself, it does not mean cheap or even cost effective :cry, yet we all wish it did and take this path in order to cut costs. In the case of this bag [like the NIKE MAG shoes], you can't actually buy one in a shop. If NIKE had released these at a "affordable" price , I am sure they would have sold thousands around the world.

    So anyway, onto my BTTF inspired bag.

    I don't have a really equipped workshop here, so will do the best I can with what I have.

    These MAGs are known here as K-MAGs and HERE is a link to the thread about them.

    Re: My BTTF Inspired Bag

    Sanded all my parts back today and whilst they look better, I am not sure how I am going to make the sliding action for the lids without buying another section of pipe just for them.

    Re: My BTTF Inspired Bag

    Thanks guys. I have the day off today, so might run the lids down to a local plastics fabricator's work shop with a table saw and trim them up a touch. The body is looking good so far. I can also order the two ends off him as well. He will probably just cut the ends out on his router and flame the edges.

    I know the real bag has a fogged look to these ends (it also went from solid to translucent in the film) and because my bad is "inspired" by and not a true replica, I might get 10% tint here rather than clear. The real bag looks to be painted and the guys that made awesome replicas covered theirs in cloth. I am thinking that sexy graphite adhesive here just to be a little different, not 100% sure yet. Thoughts?

    The challenge I am facing right now is how to make the lids slide around the body. The angled ends of the real bag are what covered the ends of the lids and I am still on the hunt for something that might work here for me.

    Anyway here is another pic :)

    Re: My BTTF Inspired Bag

    And back from the Mr Plastics [a shameless plug] who not only supplied the inserts but also trimmed my lids as well. He was actually surprised how straight I got them given the tools I had to work with. He asked what it was to which I took the easy path and told him a display case.

    I was expecting him to cut these out using the router, but he didn't. He simply traced the inner circle of the main tube, marked an x on both the tube and one spot of the insert and then trimmed them to a rough size on a band saw, then finished them on a really big disc sander. And they fit like a glove. I've known the guy for about 12 years and he knows his stuff.

    [​IMG]

    The ends may look solid here, but they are indeed tinted clear. I was kind of thinking I needed to back light to show this, but all in good time.

    I also took a look at some stuff for the cosmetic finish of this project and they don't have the graphite that I wanted. They do have this really cool almost holographic stuff that comes in a variety of colours called ROWLUX - Illusion Film. A bit pricey at just under $70/LM and then the adhesive as it is not self adhesive. Will have to think about that one. It would certainly turn heads though.

    So a question - what to use to glue in the end panels? Body is PVC and ends are acrylic.

    Re: My BTTF Inspired Bag

    UPDATE: Bought some 3M Carbon Fibre wrap today. It is supposed to have some form of ribbing on the back to help release air bubbles.

    Still undecided on how to attach the lids. I might just go hinged as I can't really find anything that is going to allow me to make the lids slide around the case and to custom something up will increase the cost too much.

    Got a quote from a sign mob to do the NIKE FOOTWEAR logo for around $30 in a nice bright yellow.

    Re: My BTTF Inspired Bag

    UPDATE: The tube is now a combination of PVC (main body), Perspex (ends) and Poly Carbonate (Lid rests). Because there is three different types of plastic used, I can't use a standard solvent. I have found a clear adhesive that I hope will work out. The unit is glued and I have to give it about 24 hours.

    Image coming soon

    Not quite 24 hours :rolleyes but the glue appears to have set. Enough to take this image which shows the poly carb in place :eek
    [​IMG]
    I played around tonight with the idea of making the lids slide into the body, but found that I was going to lose too much internal space. Therefore the lids will be hinged.

    OK lids and handles done.

    [​IMG]

    [​IMG]

    I am not 100% happy because (and my own fault) I have used the cutouts to make the lids to save costs. They are undersized and don't sit as well as they should. So I guess I am going to have to buy another section of pipe and re-do the lids before I attach my expensive vinyl wrap as that cost as much as the whole cost of the plastic parts of this project so far.

    Also, the polycarb used inside as supports for the lids has appeared to crazy cracked. I am not sure if it is just the amount of stress the plastic is under or the clear adhesive I used has attacked the plastic. Either way, it needs to be replaced. The best thing to do would be to have to rings cut when I buy more pipe and remove a small section to allow then to fit inside and use that solvent cement (normally blue, though clear is now available) to bond these in place.

    Re: My BTTF Inspired Bag

    Time for another update. Today I bit the bullet and bought another section of pipe to redo the lids. When I went to purchase the pipe, I noticed that the flanged end was still on the end and asked if I could have that as well. So I got two lids, 2 x 35mm rings from the flange (to thicken the ends) and a 2nd set of 35mm rings to replace the polycarb that has cracked and looks rather nasty now. Being all PVC, I'll be able to bond the parts using the proper PVC solvent. Images coming soon.

    The new lids are a much better fit.

    The new thicker ends have been fitted. Tomorrow I'll knock out the polycarb lid rests and replace them with the two big PVC rings. They are the same OD as the main body and so I need to remove about 38mm to allow them to be compressed and fit snug inside. Because there is now 12mm of plastic on the ends, I will recess the two tinted perspex ends to 12mm as well (a further 6mm).

    Because I bought the whole section of tube, I actually have the balance of the part from which the lids were cut and playing with this tonight, I may be able to use that other part as a false floor which should allow the lids to slide inside the body.

    Lucky this is a prop because with all the extra plastic it is really heavy now and if I actually use this thing, I'll end looking like this guy

    Re: My BTTF Inspired Bag

    [​IMG]

    OK pulled the old tube bag apart and rebuilt and I think this version looks much better. There is slight high spot on one end of the lids (nothing a quick sand won't fix) and I will need to find myself a dremil or similar to trim out some excess plastic. I am actually leaning to a small router and trim bit so the bearing can follow the profile of the plastic I wish to leave in place.

    So the changes are new lids and thicker ends. I also removed the polycarb and replaced that with the PVC (after removing a small bit to allow compression) rings and with the help of the young son, put the thing back together. WOW a 2nd pair of hands makes such a difference on a project like this :$

    The ends are now recessed a further 10mm (now 16mm) where before they are recessed just 6mm and I like the look much better.

    The idea of the lids sliding into the body was a massive fail. I am sure I can do it, but not on this tube bag. Maybe the next one as I have several bits pieces left over from this modification that I could do something with.

    So trim time tomorrow. After I am finally happy with the trimming, I will remove the rivets that hold the lids on, laminate with the Carbon Fibre adhesive and use stainless steel hardware (with lock nuts). I also came up with a small locking mechanism that should look quite neat as well.

    Re: My BTTF Inspired Bag

    Got a price back from a sign maker to make the decals. $66 in a gloss. Sounds a tad pricey, but hey if that is what it cost, so be it. I will also be getting some SWOOSHES made up for the shoes rather than attempting an exacto knife job. I really want to add some "bling" to the tube bag and shoes so for an extra $22, I was told I could have reflective tape!

    The thumb nail at the bottom is my 1:1 art work for the Tube bag. I used a proper NIKE/SWOOSH logo I found on the net (after removing the Registered logos) and then imported that into Paint. I then used Verdana at font in bold at size 500 to type the word FOOTWEAR. I then compressed the word to 50% of the original height. This affected some of the letters which I then altered to make the graphic I have. It is not 100%, but will pass.

    Oops, just took a look at my art work verses the one supplied by a member here and my NIKE logo is too large.

    Hopefully this one (NIKE is now 85% of original) looks better.

    :cool
    And this brings this project to an almost end of life.
    [​IMG]

    I've updated this image to show the shoes now painted grey. I am impressed with how much difference some stickers make. What I need to do is remove the lids again and black out the edges of the PVC and then add my locking mech and I am done with this one :cool

    Total build price is $221.50 [over twice as much as I intended to spend].

    Breakdown:
    PVC and tinted ends plus labor $50
    Carbon Fibre Wrap $50
    Hardware [Stanless Steel bolts and handles] $17.50
    Decals $88.00 [this also included some decals for the shoes].
    Car Carpet [for the liner] $16.00

    Re: My BTTF Inspired Bag

    Because the bag is a "tube", it won't sit upright well on hard surfaces. It tends to want to roll and to capture this required some propping behind the bag.

    [​IMG]

    So my solution was to add some feet. Whilst thinking about what and how to do this [and actively seeking part for another project], I discovered I had a heap of 80mm discs [made from 10mm black perspex] left over from some laser cutting I had done. So I drew them onto the tube bag I had created in Sketch Up for a better look.

    [​IMG]

    At first I was not really sure about how to attach these. I ended up drilling and tapping the centre to M4 and the disc is essentially the nut to the small bolt [that will be replaced with a dome head soon] that passes from the inside. This will soon be covered by the liner.

    [​IMG]

    So now the bag can sit upright anywhere :love

    Re: My BTTF Inspired Bag

    As I get closer to getting my Vac Forming set up, I have had a long hard think about how I could have made this bag better. So I thought I would just put this out there. I don't have a specific time frame in mind. It is on my to do list though.

    [​IMG]

    The Tube bag I made is nice, but it is heavy and the lids are hinged and don't slide around like they should. The ends don't have the taper and the handles are not recessed as they should be. It was my first attempt and I am still happy with the results.

    So after some thought, I think Vac Forming the parts [ plus laser cutting the clear ends] is the best way to this.

    The Parts
    [​IMG]

    The Tube bag is made up of 1 body, 2 ends, 2 lids and 2 clear inserts. Based on what parts I have left over from the first project, I should have enough tube to made bucks for this project.

    The End Cap
    [​IMG]

    I plan on making the buck out of 2 layers of 25mm MFD. Because Vac Forming takes a mold of the outer skin, I needed to work out how and where the body and lids will sit as well as having a recess to attach the clear ends.
    I have already planned feet to so the bag can stand upright on its own.
    Recessed Handles
    [​IMG]

    I am still working the bugs out of this part, but think I have it sorted. The plan is to pull the body from the inside of the pipe and pull the lids from the outside of the pipe. This gives me two different diameters and the lids should easily wrap around the body. I just have to tweak the end cap. I also need to work out what part of the final pull will be required to be cut out.

    Anyway, this is just food for thought at this time.

    Re: My BTTF Inspired Bag

    :thumbsup Thanks guys :)

    I ran a suction test on the Vac Form table today because I had a doubt that the VAX I want to use (will now be using) would have enough grunt. I laid a 500mm x 500mm piece of 16mm MDF that just covered all the holes, fired up the VAX and I could not lift the MDF off. In fact the whole table came up. The only way to lift the sheet was to turn the VAX off. Pretty impressive for an old wet/dry unit I was going to toss :cool

    I also found a portable heater that should do the job at Bunning for less $20.00. I've drawn up the heat unit, I just need to contact the sheet metal fabricators for a price on some gal.

    Not at this stage. I have been thinking about doing a run of these. It is just a matter of sorting out the details.

    If I do a run, I'd make them screen accurate. In the posts above I mention Vac Forming, however the shell should be made from fiberglass like the screen used prop.

    Either way, the handles will be recessed and lids will wrap around the body on the new version and it will be much lighter than the PVC pipe version I have made.

    I have no idea of cost of materials at this stage. If I do a run, they will not be covered in carbon fiber like mine, so there is a $50 saving right up :thumbsup

    When I am ready to go (sorry I don't not have a time line) I will be running an INT thread in the JY first.

    Yours looks awesome, hope mine comes out have as good as yours. I have a pvc tube that is about 10.5-11 inches in diameter that was given to me for free at at construction yard. Had about five feet worth, enough for a base for my slime blower and for a Nike Bag. Will hopefully start that project sometime soon.
