Very good 2nd video... In the last decades of the last century you could buy vertikal band saws with 2 speeds one for wood one for metal and all the technique behind was some simple gears. Now you do the modern version of this. . Top content...
I too will be converting a bandsaw for metal cutting and appreciate the videos. Curious to know what size RPC you are using in your shop, and how many machines are operating off it. Maybe a short video on the RPC and how it is connected to the machines?
Word to the wise, never use a 4 flute tap when power taping . Use a 3 flute or a screw type super tap. I can only give you my 50 years of experience of manual machining, not a hater. Video looks good to me .
It's as Powermatic 141 right? I have the exact same machine, perhaps a little older though. I have been trying to figure out a simple way to have my cake and eat it too, i.e. be able to change speed between wood cutting and metal cutting. Looking forward to your mod. Question: What are the horsepower specs on the reducer you are using? And what is the horsepower on the motor?
Jacques Rioux I converted my bandsaw to wood/metal by swapping original 3/4 HP induction motor with 2HP DC motor from a treadmill. You do not need that much power but 1,5-2 HP is typical for treadmill. Those old treadmills are an excellent source of controllable power source. Anyway, the DC motors have good torque, spin fast and are easy to control. Large pulley on the saw, small on the motor and you are almost done. If the original control circuit from the treadmill is still working use it as the simplest route. If it is dead get an oversized SCR power controller from eBay, connect output of SCR box to bridge rectifier (KBPC3510 is an overkill but easy to mount) then DC output of the bridge to the motor and you are done. Those motors have wide RPM range ( usually up to 4-6k ) so you change the blade and dial the speed to the material you want to cut. I did start with induction motor+worm gear+multi grove pulley conversion but changing gears was too time consuming. A 3-phase motor on VFD is way more expensive than a used treadmill but if you can get those parts cheap then it is a very good “industrial” setup.
Keep up the hard work. It is not easy for small shops, AKA, find work produce quality work, ship work, bill for work, Collect for work ! $$$ pay bills... keep up the long hours and hard work. Thank you. Sir
Cody3232 Cody3232 Look up the price of a VFD and 1HP 3-phase motor and you will have the answer. Even used ones are fairly expensive. Worm gear reducers are much cheaper.
Much better video quality. A huge improvement over week 1, nice. Interesting content.

You can also demultiply the motor ration and then put on a variable speed clutch.
But that would be way too much work I guess...
Great improvement, keep with the good work! Respect
love it "if i screw up my next video be how to unscrew up!" lol
Good man keep at it you obviouslylove it.
Got an old Delta vertical bandsaw I need to convert as well. Looking forward to part 2.
Thanks for stopping by. And yes I should have this project done here soon. And im excited to finally use it.
I'm a new subscriber. love your videos so far!!!
Think smart, play smart!!
Thanks
Watching and liking. Will your Horizonal Saw not stand up to use as a Vertical Saw.

Thank you. Sir
Thank you for your support it means a lot and is very motivational and will help me stay on top of making these videos and growing my shop.
Why couldnt you use a vfd to slow it down?
