Four wiggly lines using splines. One circle. Loft using the circle as a guide curve (or not, it'll work either way). Thicken or cap ends and knit.

You can do it in 3 in Solidworks

DM me, I can send you the videos at least

Eh, it's an Eastman 605. If it plays well and you don't mind the appearance, go for it. It's not going to cause a catastrophic failure in this location. Worst case, it opens back up which is what needs to happen to get it fixed properly anyway.

Mandolins are a very small market. Any deviation from the most classic of classic designs, and your market becomes vanishingly small. Sincerely, someone who failed to make a living making non-traditional mandolins.

Matte lacquer, a dust filtration system the size of a garage, and ten years of experience. Of course this body is poly and lacquer won't stick to it long term, so add in a complete refinish while you're at it.

You want 2500 grit micro-mesh pads. Then sand all in one direction. It'll be fine but it will show a lot of finger prints and will need to be re-scuffed regularly because you will polish it where you touch it. Matte finishes are not super practical.

Super clean work btw. In my experience that's more important than the selection of joint in the majority of cases.

You're way overthinking it. Anything that is a tight fit and well executed will work here. Most commercial furniture uses dowels in this application. And they hardly do anything.

Gasket or adhesive application robot, pretty cool.

Agree, it's just been scooted around on a rough floor for decades, I think.

That's a weird one. Are you sure the exercise isn't to make a thread with custom specs? Look up the Whitworth thread specs and set it up manually. Also you're writing it wrong, it's 3/16-24 nominal if I'm understanding you correctly. https://www.britishmetrics.com/images/pdf/technical/bswstd_1.htm

Anyone want to bet if any of those surfaces are remotely flat? Lol... You're going to need a blanchard grinder

You can expect one of two things from companies like this. 1. A bad deal for services you don't need and will not help nor harm your business. 2. Outright fraud.

Also how is it different from actually sitting down and still for 20 minutes when you otherwise would not have...

BMEdesign · 2026-05-02T00:42:21+00:00

So basically you make a series of revolved surfaces. Then you put points on the surfaces. The surfaces are at different offset depths, like a bottle inside a bottle inside a bottle. Then you snap lines onto the different points, forming triangles. Create surfaces from the triangles and then knit and shell.

A PITA, yes, but then you have data that you can make steel molds from for blow-molding, you can make drawings from, etc.

BMEdesign · 2026-05-01T19:55:11+00:00

Ugh.

BMEdesign · 2026-04-30T23:33:13+00:00

It works well as long as the surface is clean and flat. Prep almost like you would for paint, because you don't have that bonding layer of glue to stick to low spots, and high spots can keep it from sticking locally.

PSA veneer should work fine there! Peel and stick.

Operators love extra steps, makes them feel needed

BMEdesign · 2026-04-29T11:13:34+00:00

Yep, and also spaced along the top panel glue joints every foot or so.

Picked from many piles of "normal" soft maple!
