If your going to do this then use peel ply between the board and the breather.

Awesome Video! I'm a snowboarder myself and was looking into doing something similar to this. Did you make that vacuum press yourself? Also how was the experience? Would you recommend others to try it?

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..

Hi Jeremy, What problem you was have with pressure??? Are you think is better to go with two hoses on both side for vacuum??? and where you both the valves and hoses for vacuum press??? Thank you

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.

Jeremy you are awesome!!! Thank you so much for detail answer, a lots of your ideas help me to decide in witch direction I want go, I have previous experience with wakeboards but I never use vacuum and one side press... I will made 3D shape, right now I am still working on press and materials is on way.. Do you think is better to I make seal valve or to just wrap house inside film vacuum? Thank you Jeremy I will put your link in description when I make full video :) Cheers!!!

Looks Great im looking into vaccum bagging my first board i just have a few questions. 1. Between your wooden mould and the base what material did you use? Is that just a plastic perspex type sheet between the base? 2. IS the layup as follows. Wood mould - plastic -snowboard layup - Breather fabric - Vaccum film?

1. yes - i just used a thin piece of plexiglass - 1/16". it doesn't need to be very strong. 2. yes again - mold > plexiglass > sintered base (pre-covered in epoxy) > fiberglass (with epoxy) > wooden core (pre-covered in epoxy) > fiberglass (with epoxy) > rice paper graphics > top sheet > breather fabric > vacuum bag top sheet (technically I didn't bag it).Then in the video because it got too cold in my garage I put an electric blanket on it. Hope this helps and I'm happy to go into further detail if you needed. It was a great project and I highly recommend it.

@@toothlesscoot excellent thanks mate. Still deciding weather or not I'm going to vaccum bag it or a straight wood press! When you say you precovered the base and core with epoxy did you apply a thin layer and let it get tacky to help with the bond prior?

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.

purchased in a kit that is pre-measured from the link below. depending on the size of your board you may not need to use all of the epoxy on your board. i was able to leave a couple of oz's out on a 156 and it trimmed some weight. snowboardmaterials.com/index.php/materials/epoxy-resin

i used an inkjet printer on rice paper and it seems to have worked out very well. i got my vacuum supplies here. www.snowboardmaterials.com/index.php/materials/vacuum-supplies i bought my vacuum pump off of eBay for about $125. definitely go with a Gast pump as they will last a long time and even keep their resale value. they are used in medical applications and there should be plenty of them on eBay. mine is a gast moa-v176-ca. 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.

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.
