Tool for shaving back braces

I am retopping a guitar and while it's open I want to reduce the mass of the back braces. Since the sides are in the way, I can't figure out how to cleanly cut the excess brace wood away; anything I've tried involves the handle hitting the sides and preventing a controlled, clean cut. Is there a tool - say a "pull finger plane" - that I can pull from the edge to the middle of each brace to facilitate this?

My problem in this parlor guitar is that any chisel I currently have is too long and I can’t address the middle third of the brace without coming in at such an angle that I can’t control the chisel pr…

“I live my life a 1/8 mm at a time”

Guitar neck topology is worth going microscopic. 🔬🦠 After building my starting surface from a wireframe network in the sketch environment; a system of 4-degree control point spline rails, tangent to projected isoparametric curves along the shaft — I can convert the NURBS surface to a T-Spline and start cleaning up the artifacts left behind by the original loft. In this demo I’m turning on Box Display, which feels strange at first because…

Brett -- If you are doing free-form modelling, have you tried using Shapr3D software? I just started playing around with it and it seems to be reasonably intuitive and easy with which to get started.…

2 Surface 2 Transition

Back at tinkering with the new Isoparametric Curve tool in Fusion. Scroll down to PICTURES LETS GO! If you want to skip this little walk through Autodesk Fusion memory lane, clearing up some of the UI conFusion. Why something so seemingly basic, is just being added today. 2009- Autodesk Inventor, hybrid modelling experiment, parametric and direct CAD in one hybrid system. 2011- Autodesk acquires T Splines Inc. an organic modeller still in…

Fusion Surface Transition Update

I had a feeling I should have updated Fusion before 3D Club... Todays New update introduced Project Isoparametric Curves "Isoparametric curves in the Sketch environment, adding new ways to extract surface U and V curves for more controlled lofts, rails, and surface transitions" ...The meridians on the shaft surface seen in the attached photo. I still haven't fully grasped how to align these between faces, attached is a quick…

3D file of a PRS style control cavity template for 2 pot + 1 switch

I need to make a router template for a rear access control cavity in the PRS style of 1 vol +1 tone +1 switch? Placement of pot and switch holes aren't important, just the contours of the cavity so I can print a routing template. Does anyone have a file? Thanks! Justin

Shop humidity: Am I nuts to focus on dew point instead of relative humidity?

Not sure if this is the best place for this, but whatever. I need somebody to check my logic here--I could be completely wrong in my thinking. I'm about to start up my new shop in Ireland, and the humidity/temperature situation is VERY different than the Greater Washington DC region. I will also be unlikely to have as complete control over temperature and humidity as I did in our extremely tight, air-conditioned house in the US. I also k…

Maybe ask other Ireland luths? @member Maybe your shop should be somewhat dryer than the dryest that your customers homes would be?

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,…

This is great. Thanks for sharing! The thermocouple link takes me to the thermocouple outlets? Might be a caching issue for me? Joe

Homemade Gramil

This is my second iteration of a gramil that can be used to fully cut the channels for binding and purfling as opposed to using an electric router. I am working on my first acoustic now but initial tests look promising. Features round beam so you can lightly scratch at first like a marking gauge. Depth control of the exacto hobby #11 blade. The edge for the beam is also shaped so it won't pop out like other wedges. Pretty quick to make…
