A radius sanding block is an essential tool when making guitars and one you can easily make yourself.
In this video I will show you how I make my Radius Sanding Blocks from scratch.

I took just a block of wood, radius cauge and plastic padding. I made a curve on the wood with cauge. Then I used this block to sand the radius block. Took few minutes and it's perfect.

Great. Very well done. Way better than paying $180 at certain well known Luthier supply shop.

Thank you for your video. I am a ukulele builder who also makes most of my jigs, including radius dishes, bending irons, binding cutting jigs, etc. I look forward to more of your videos.

Thank you for this video - very helpful. I had thought about that kind of jig for making necks with different radii (radiuses?) but I just couldn't warp my head around it. Yours makes so much sense. Thanks again.

Thank you for making the video. Smart solution well executed, but for most ppl not very practical. Properly planing the block is a pro job and requires a rather expensive plane. if you buying the block pre-planed you might just as well buy an sanding block. Kudos anyway!

Made one using a Dremel, not powerful enough. It worked, but took too long. Bought a $30 router at harbor freight and upgraded the jig, works great!

hi this is a really good video it inspired me so much, i wanna make the same machine, can you please give more details about it, i really like the way that you calculate the radius, can you show me how? i think that the guitar that i have to fix is a 9.5, you know how to calculate the radius of a guitar without tools to?

That is a very good method
