The gear drive I contributed to my homemade band saw worked, but was remarkably loud. It was bad enough that I chose to return it to the belt drive, but with a flat multi-V belt this time AND sheaves that are 3D printed.
Why? Because I can and I'm curious to see how well 3D printed parts stand up to real world usage. No they are not as durable as "correct" sheaves, but they are a tiny portion of the cost and can be designed and made to the size you require. That is a big upside for somebody who makes his own tools since it removes the limitation of working with what you can find.
Next I restore the table and trunnions. This time I used 1/4" thick aluminum plate for the parts to make it additional strong.
Why? For practice, generally. I have at least one big maker develop turning up that I'll be making from the exact same aluminum in the very same way, so I require to get good at using the software and the metal cutting CNC to restrict the errors I make on the larger project.
The new table is a significant improvement over the 3D printed one AND the original one made from plywood. It's solid, durable and easy to adjust, plus the aluminum is a lot slicker and doesn't "grip" the stock as it's being pressed into the blade. It can be anodized to make it even harder (or color it a various colour), however I like the "frosted" look it obtains from sanding it with a random orbit sander.

The gear drive I added to my homemade band saw worked, but was insanely noisy. It was bad enough that I decided to return it to the belt drive, but with a flat multi-V belt this time AND pulleys that are 3D printed.
Why? Because I can and I’m curious to see how well 3D printed parts stand up to real world usage. No they are not as durable as “proper” pulleys, but they are a tiny fraction of the cost and can be designed and made to the size you need. That is a HUGE upside for someone who makes his own tools because it takes away the limit of working with what you can find.
Next I rebuilt the table and trunnions. This time I used 1/4″ thick aluminum plate for the parts to make it extra strong.
Why? For practice, mainly. I have at least one big machine build coming up that I’ll be making from the same aluminum in the same way, so I need to get good at using the software and the metal cutting CNC to limit the mistakes I make on the bigger project.

Nicely done, 3D print strength is from the outer layer, and infill is for the weight.
Great build as usual. Thanks for sharing your journey with 3D printing and CNC work.
Nice work John. We would expect nothing less from you though. You never disappoint.
beautiful work.
That’s a nice table design!
Great job. Nice to have all the good tools. A few years ago I made your 1×30 belt sander. Still working great. Love it. Thanks for the inspiration. 👍👍❤👊.
And it all goes together like it was made in a factory… well it was, your own little factory 😀
Awesome!!!
It’s so intresting watching your journey from a woodworker to a maker 🙂
I fixed my typo, can i get the heart back? ❤
Sure!
Super cool! I love the experimenting with different designs and such. I’m a fan of the aluminum table and trunions. That cnc is doing great work!
Boy I really enjoyed this video and am encouraged to keep on.
Fantastic work, John! It turned out better than I imagined! 😃
Stay safe there with your family! 🖖😊
You make it look too easy! Excellent video John.
I was about to say ‘Great work John, as always’. but I figured I should read through the comments and find out all the things you did wrong, lol. Great work John.
love the combination of 3D printed plastic, CNC’d aluminum, and wood/cut lumber. really cool build
Great job! Your trick with the counter balanced drillpress for tapping is so clever!
I will never do this but I loved watching you do it. Thanks John.
Very nice update to that band saw John! 👍👍
It’s fascinating to see these great ideas.
Love the stickers on the drill press. 😁
Awesome stuff. Really interesting project. Thanks John.
