What a cumbersome way to laminate.
I was amazed how much more rigidity you got with the side lamination. I appreciate your explanation of the vacuum bag issues and how you resolved them. Nice to know the troubles one can run into on a guitar build. Looking forward to seeing this acoustic guitar taking shape.
Good, informative video - thanks for sharing! One tip, though; switch from wax paper to parchment paper and you'll have much better results.
GP that looks like a nerve racking operation but you handled it! Nice work 👍👍
Thanks Matt! When the clock starts, its definitely GO TIME!!!
That was awesome Greg
Thank you Tom!
I'm glad they turned out well. I feel your pain in the vacuum bag. The number of times I've had it all go wrong just as the bag pulled tight. 🤦♂️ Lol
I suppose there are a few rules of engagement to learn and that was def one of them!
Yes, vacuum bags can be intense, I have not done sides but planning to do it soon, always a learning curve, also its easy to underestimate how powerful the vacuum is, also I did a furniture mold I thought was strong enough for vacuum, it got crushed like the titanic submersible, incredible pressures...
Good luck with your project!
nice job can ya share with us on how thick the veneers that your laminating are
This was brilliant. Thanks for the this man. I was thinking about doing some laminating work myself.
Thanks Amen! I haven't used the vac bag before... I'm a believer now!
That was an amazing first attempt at the vacuum bag gig. I immediately thought tape would be the answer on the first side set up. Just to get everything aligned before putting it in the bag. Of course it does get stuck to the epoxy.
I was contemplating taping and/or spring clamps. I think the spring clamps would have punctured the bag... I am going to invest in a foot control for the vacuum. I think that will let me get the bag 95% empty, then I can do my fine adjustments and let off. If not, just disengaging the hose worked pretty well. I was surprised.
@@SkyscraperGuitars, well, you can't argue with great results.
Plastic wrap works well, plastic film even better
Did you ever create videos the logical next steps in this build? I love your videos and would like to see your methodology for the completion of the project. Also, just to let you know, I just found your youtube channel and as a result, your website. I'm excited about the rental program for the side bender!!!!
Mike - The guitar is in the same state it was in at the end of this video. Shortly after I shot this I had to shift my focus to product development... I'm almost out of the weeds and I've been a few sets of sides with our new bender. I will pick this one back up along with a couple others shortly. I'll actually have some video of our new side bender in action shortly... As for the rental program... I'm waiting on one supplier to deliver, then we'll be ready to go. I'm hoping that happens in the next 2-3 weeks!
It's a good system for applying even pressure, but I think same results could be achieved in a more simple way. I would use the vacuum and side jig to make a 25mm laminated caul. I would make this over a bendy hardboard layer spacer (side thickness + thickness lightly compressed foam material) then fix the foam material to inside of the caul. The bent sides could glued placed on the side jig the caul placed on top and clamped to the side jig with even pressure. Bespoke clamps could be made from drilled steel bars and nuts and threaded rod.
I did that and although it works fine for most apllications, if your going to use a quicksetting glue like titebond its almost impossible tk get it properly clamped in time.
Skip wax paper. get thin Teflon (HDPE) sheet and attach it to the form. NOT the stuff for heat transfer forms as it is porous. Solid thin white stuff.
Coming frkm norm wood glue j quickly learned you need a ton less epoxy then you think, it doesnt dry out when hardening like wood glues so the jormal film used with wood glue will just result jn a ton of squezeout or epoxy pocket between laminations.
15 grams per surface js usually enough
👍
Thanks BlueRoads!!!
What was the thickness of your side on the venetian cutout side?
What happened? Where is the rest of the build. I was getting a lot out of it.
Nice job Greg. Wondering why you chose to go with laminate sides instead of solid wood?
Couple reasons... Overall its a stiffer system. I want the sides as rigid as possible. Also, a solid piece won't bend without snapping. This also eliminates the kerfing that is typically used. That should free up a bit more of the top. I will also be able to eliminate the vertical stiffeners that are typically seen around the inside of the body. Lastly, the mass will help bring the top frequency down a bit. That will be important in future builds, but this will give me a baseline.
That's not easy to record that ; good job Sir .
So where did you get that set up? I’m definitely interested
I have been working on the design and improvements over the last two years since I made this video... We are going to release the first retail units this weekend. If you hop on our home page, I have an email list and the folks will have the first crack at them. skyscraperguitars.com
man do I ever know what you mean! sometimes the concentration need far exceeds where the camera angle is! we need more camera men/women lol great work btw!
Ain't that the TRUTH! I don't mind when I'm going through the motions, but man... Sometimes a guy has to just DO IT!!!
I have a somewhat related question. I just acquired a 1864 decker brothers grand piano that I don’t plan on restoring. Really I got it for the legs. It’s solid Brazilian rosewood 1 inch threw out. I gather there’s a market for it for guitars and think it’s beautiful but building furniture out of it is kind of not the way to best use it. Any recommendations for where or who to talk to about selling some to makers?
I'd be happy to talk about it with you. I have the means to process pieces like that into buildable guitar sets. I can't post my email address here, but if you go to our website and use the "Contact" form, we can connect via email. It would be better to exchange phone numbers or arrange a zoom call that way. skyscraperguitars.com/contact/
@@SkyscraperGuitars thank you. I went to the website-contact us and sent a message with my number. I’m heading to meet the movers for the pickup and delivery in 3 hours so should have possession of the piano by noon ish.
@@leekeeton214 I looked for your message and it appears our contact form page was not working correctly. I believe it's fixed now. Can you drop me another line? I apologize for the duplicate request... I wish I was a better website nerd so I could make this easier! Thanks, Greg
