Could you give us feedbacks on how your board performed and aged ? I've found very few feedbacks on this method, and rare ones I found were often observing delaminations (unless the board wasn't used, of course). Vacuum pressing is great for many applications, but when it comes to building snowboards it sounds very weak compared to presses the industry needs to use.

I like the way you did it. I build planes with this technique and i think it could have actually a higher quality result than with a Press. Long story short: i want do build a boart too but i have some concerns due to my experience with planebuilds. Did you have any air bubbles under your topsheet? Because in my plane moulds i use an air permeable top sheet, wich is removed later. The problem is: to get a smooth surface i need to grind a lot. How thick are the sidewalls (or the difference between bottomsheet and woodcore)? Iam plannig to do a 3d printed mould with a steelsheet to suck a vacuum.

hey im almost ready to vacuum my first board! i just bought a 2.5 CFM vacuum pump from harbor freight (Pittsburgh automotive is the brand). I was wondering if you could provide any input if this will be a strong enough vacuum. Besides the vacuum, did you just need tubing and a vacuum gauge? did you continuously run the vacuum pump while pressing? sorry for bombarding you with questions!

You’re just about ready to roll. That pump should have more than enough power question is will it be happy running for 24 hours. I’m guessing it’s designed for bleeding automotive brake fluid - hence the brand. I bet it’s fine. Couple of things to consider. Pressure is measured in Hg so cfm isn’t important. Technically, if your vacuum seals properly you’ll be pulling 0cfm. :-) So yes, get a pressure gauge and run a test to see you have ~24hg. You will need to run the pump for ~24hrs. I highly recommend breather fabric. I bought all my supplies at snowboard materials.com but any vacuum supply biz will have what you need. Also, as you may have read in my other replies- I jacked up my first board by putting the tube on it. Pay attention to the placement of the tube. Happy to answer additional questions.

@@toothlesscoot I appreciate the quick response! I am also worried about continuously running that pump. I was wondering if I could use a shut off valve after achieving a good enough vacuum and turn the pump back on as needed. I saw your comment pointing out how the tube was on top of the board. How would you recommend I attach the tube to the vacuum film? Is there a certain type of tube you would suggest? Thanks again for the help!

@@davidanderson2844 You will likely be fine running the pump for 24 hours (except Harbor Freight. tools can be a gamble - i gamble plenty with them). However, it would probably only do it so many times.. but since you're not running a snowboard factory... that said, once the epoxy has set (a couple of hours+) you could probably give the pump a rest if its getting hot. as you mentioned, you might not lose pressure with the pump off.. that is certainly true with the Gast pumps but with the Harbor Freight - worth a test. As per the tube connection, I just bought clear tubing from the hardware store - something rigid enough to handle the pressure. As per the connection, I used vacuum sealant tape each time (just made a very thick layer between the film and the plexi form base that the tube passed through - and it worked fine. they do make vacuum film gaskets, etc. but that seemed to be for a reusable application. For the record, I pressed little tests of scrap materials before doing my first board and i'm glad I did. Once you mix that epoxy the pressure is on - literally. let me know how it goes..

I can't say for sure because pressing a snowboard requires that you run the pump for at least 24 hours. I wouldn't imagine that an oil extraction pump is designed for that kind of run time. However, I'm betting that it takes a good deal of suction to extract oil, so it seems worth a shot. I would definitely run an overnight test on a vacuum bag so you are sure your motor isn't going to burn out when pressing the actual board. A failure that close to completion would be a real bummer. Be sure your test replicates the actual use case (pulling on a vacuum that is already at max pressure for a long time). Good luck!

Awesome video!! Can you explain how the vacuum mold makes your camber profile without the use of any compression? My understanding is that the vacuum is used to both remove air bubbles and applies even suction/pressure down against the mold to create your camber and tip/tail profile.. is this accurate??? Awesome video!!! Thanks.. do you use everything from www.snowboardmaterials.com ?
@toothlesscoot
4 жыл бұрын
Your understanding is correct. You can see that my camber is defined by the curvature of the mold (wood slats). When the air is pulled out of the vacuum chamber, and bc the mold is rigid, the vacuum film is pulled down, toward the mold. Thus, anything under the film will be bent to the shape of the rigid mold below. Hope that makes sense.. Sounds like you get it. This is the basis of a lot of great projects once you have the concepts and tools.

I put down a layer of contact paper between the snowboard and the plexiglass. this allowed me to simply peel up the contact paper and reuse the plexiglass multiple times. That said, I never had a snowboard/epoxy adhered to the contact paper. Every board came right up - just a little pop and it was free.

@@fridthjofsimonsen8108 i purchased an epoxy kit from here: snowboardmaterials.com/index.php/materials/epoxy-resin which states "approximately 30 ounces mixed" per board/ski. however, my first boards came out a bit heavy so I scaled back the epoxy on my later boards. one thing i did to help control up the application was split up the epoxy into equal containers (after mixing) for the two layers of glass (i think i show this in the video with the little plastic cups). i also worked the glass and base/core in a more step-wise manner.. adding epoxy as needed rather than just assuming i needed all of the allotted epoxy for each layer. my later boards were much lighter and just as strong. hope that helps.

i have heard of folks using shop vacs but i can't say it sounds like a good idea. you need to leave them running for 24+ hours and a vacuum pump like the one i used won't lose pressure even if you turn off the pump (assuming your vacuum is properly sealed). because of this, the pump really doesn't have to work too hard once it gets up to pressure. however, if you have a perfect seal and you turn your poor shop vac loose sucking on something that can't be any more pressurized for 24 hours - you are very likely to burn up the motor and make your neighbors mad at the same time. that said, if you can find some folks that did it successfully.. absolutely go for it. as per the press. i highly recommend going with a vacuum until you have a sense of what is required to make all the components, etc. and with a vacuum press you will be on your new board in no time. a pneumatic press is a large project on its own you can move up to one after you have the vac press process down. btw - if you are going to go the press route you will want to use an air compressor + air bladder, like old firehoses, held within a fixed frame.. its the tried and true method (note: it can be dangerous). here is an affordable pneumatic press made with fabric. www.skibuilders.com/phpBB2/viewtopic.php?t=1820&postdays=0&postorder=asc&start=0 here is the much more common pneumatic press setup with fixed frame www.skibuilders.com/phpBB2/viewtopic.php?t=668&postdays=0&postorder=asc&start=45 do some research on skibuilders.com.. there are some amazing builders on there. almost everyone without access to a proper shop (welder, etc.) ends up at the vacuum press method. either way you go - enjoy!

@toothlesscoot
5 жыл бұрын
I did several boards and had a similar issue on each one. When everything was ready to go and we turned on the pump we just didn't get full pressure - and there was no obvious hissing leak. I repeatedly checked the outer seal of the vacuum film and the vacuum tape, especially where the hose entered.. nothing. i had almost given up when i ran my hand over the surface of the vacuum film and the pressure would shoot up and then back down. Turns out there were imperceptible holes in the vacuum film surface. I can't be sure but it is my guess that these holes came from the fiberglass. The snowboard top sheet should/would keep any fiberglass from contacting the vacuum film directly during press so I have a hunch that the holes were made when all my materials were stored or shipped together. Either way, I threw a little packing tape over the area of the vacuum film and presto - full pressure. As per the two hoses, no need. One hose is fine. In this video I accidentally have the hose in contact with the board.. big mistake - left an indention. Make sure to run your hose on the side. As long as you use vacuum breather fabric you should be good to go. good luck and feel free to ask more questions.

Alex McNett indeed, a full vacuum bag is an option, however from my research it can be a bit difficult to do the layup of the various layers only to have to pick up the entire mold and get it inside a bag (like getting a body into a trash bag). I saw folks do it online and it was quite an involved process that seemed risky in the heat of the layup. As well, once used the film/bag are likely to be covered in epoxy and must be thrown away. Bags cost a lot more than a roll of film. IMO, bags are best used to press multi-sided objects like adhering veneer to 3 dimensional shapes - think bass drum veneer - definitely a bag scenario. Hope this helps.

you can read about and purchase the epoxy that I used here: .snowboardmaterials.com/index.php/materials/epoxy-resin many people use boat repair epoxy which you can buy at a marina - it is very strong but may not have the same properties that the snowboard/ski specific epoxy has. probably a minor difference but good to know. see my response below for more details.

Just make sure you use epoxy and not polyester resin. It's not so much about the type of epoxy as it is about the mix of epoxy and hardener. Too much hardener and your board will be brittle as hell. Too little and the fibers won't set right, leaving your board floppy and uncured.

Show less it's worth mentioning that i spent a lot of time preparing for this build: purchasing supplies, making the mold, making the templates (core and base). then doing all of the prep work, cutting base, core, bending edges, etc. the final build only took 45 minutes of layup. point being.. don't be in a hurry.. but once you get your first one built you can make additional boards pretty quickly.
