D28 blowout

Hi all, I'd like to get some input on how to address this top blowout. For starters I own this, I got it as a project guitar, 71 D28. I'm not as experienced with acoustics as electrics and this is a big project but I got it to learn new skills and I'm confident I can do it with guidance. It had been stored in the case for many years under tension and was way too humidified. The bridge had pulled up I assume in stages. The center seam se…

Non-CNC cauls for Stew-Mac sound hole clamps

I don’t have CNC capabilities so I could not duplicate Dave Slimmer’s version ( https://loothgroup.com/loothprint/bridge-clamping-cauls/). Got a 12x18x1/2 inch HDPE cutting board on Amazon for under $10 (https://www.amazon.com/dp/B001D3LQVA), drilled a row of 1/2 holes about 5/16” deep with a Forstner, cut the HDPE into 5 sided chunks so I could orient by touch, and free handed the brace grooves on the band saw. The clamp swivel pads are 1…

Yeah, I think the current concerns with microplastics is impacting cutting board prices.

Measured drawing and assembly for Proper Variable Radius Sanding Jig

Doug Proper designed a sanding jig that supports variable concave and convex curves, described in the following Loothgroup article: https://loothgroup.com/post-imgcap/the-variable-radius-sander/ I built one and am impressed with how it facilitates preparing bridges, braces and also allows tracing any radius using the chord formula. I made a rough measured drawing and assembly guide to share, with Doug's blessing. First step, ma…

Free 3d printed stuff up for grabs

Santa heard I had a challenging year so he got me a 3d printer for Christmas. I’ve been printing like crazy, learning the machine. This has resulted in a bunch of tools that either don’t work for me, were attempts at mixing colors, or have very minor printing blemishes. Two lots up for grabs to anyone in the US who wants either. I’ll mail to you for free. First one to claim each gets it :) First lot has parametric nut and saddle sanders…

Lot #1 still available. I'll likely be adding to the lot as I print and eff up but still make usable prints.

What would you like to see in a luthiery Fusion360 plugin?

As one does, I got distracted designing a fretboard for my newest acoustic build and thought 'Wouldn't it be great if there was a plugin to do this automatically?' Several days and 1000 lines of Python later, it's definitely possible. But then I thought "What else might be interesting as part of a plugin like this?" So I'd love to hear what you think, including: - Is this something you think is valuable (irrespective of price) - If it is va…

Headfirst into the CNC deep end today

I'm the proud new owner of a "new to me" Fireball Meteor CNC machine. It feels really odd to have a computer in the shop but I guess I need to get used to that. Fortunately for me, I am well versed in CAD, unfortunately not so much on the CAM side of things. My 3 kids are all experts and are steepening the learning curve dramatically, this would be overwhelming if they weren't helping. So far I'm using the Fusion 360 personal use versio…

Here's the video of how it's going so far, skip to 18:48 for the CNC part. https://www.youtube.com/watch?v=hyoosBNV6xQ Pretty good I think but I still have a long ways to go. My youngest son and I did g…

Seal Lite 3D scanner is here!

Not exactly 3D Printing but it’s the closest sub-category. After backing an Indiegogo project back in August, my Seal Lite finally arrived! My first impression is that this thing is pretty freaking cool. I tested it out after skimming the tutorial (because that’s the true test of interface ) and received halfway decent results. I put maybe 20-25 minutes of use on it this evening, and I’m excited to give it a more proper dive over the wee…

I agree that it would be hard not to get infatuated with using it. I’d be looking around the shop for things to scan and then make!!! Oh wait, guitars right. That’s the focus. I think for that pric…

Brown's Guitar Factory bridge plate tool modification

Have you ever had a really stubborn bridge plate to remove? I had one not too long ago that seemed to resist wetting with a damp cloth, and subsequently all the heat I could get from my silicone heating pads. After much effort I got about 80% of it out cleanly. The remaining 20% required hours of work with a finger plane. That experience made me think about the Brown's Guitar Factory bridge plate removal tool I had purchased years ago,…

Sweeping a sketch

I am currently drawing up my bridge design in Fusion 360. It has been a lot of fun and has gone really well so far. But I am a little stuck on rounding over the belly. I could easily put a fillet on it. But I want a little more round over on one side than the other. So I made a sketch on a plane of the curve I want to have. And then I try to sweep it across the belly, and it works, but it stops just shy of both ends where I want it to s…

Actually tbh I don't know how you could do a longer path on that bridge profile. Project include would just do what you already had.
