I think replacing the trigger with a pwm module control knob would have worked as well
Long reach, needle nose pliers for pulling chips, Adam's lathe is stout enough that he can machine a bolt/rod part a twice it's thickness away from the chuck, and he needs a oil lubricant, that sticks to the insert better, because all he's doing is pseudo-quenching the part/pill with that light weight coolant.
And for the love of God, science, flying cows with alien buddies, tell him to take off the ring and watch when operating the lathe. Seriously, this is the most common mistake to make. Degloving is no joke, and it's the least worst thing that can happen. Knock on wood.
17:00 Sorry abouzt my english: I have a tip for you, if you want to measure the length of the heel in waves or the like, I linked you a picture. Unfortunately I only found it in German but there are pictures.
I mean the last picture on the page. This is a bit more accurate to measure.
Great video

@@aserta I guess you didn't hear that he pretty nearly degloved his hand a couple of weeks ago?
aserta Had a close friend of mine get his glove caught working alone at night. Wrapped his whole arm up and pulled him up off the ground so he couldn’t hit the foot brake. He had to dislocate his shoulder to hit the Estop
People laugh at me about safety but I’ve meet way to many people with finger bits missing
I have really enjoyed these quarantine one day builds because it really feels like its Adams channel now. I like that it seems less scripted and more genuine.
I had thought you were going to remove the trigger button all together and run some wires over and put a Knob type variable controller on the side where you cut out the rectangle....
That's what I was hoping. The saw already has a variable speed controller in the handle, all he'd have to do is remove it, extend the wire and relocate it on the box somewhere. So much cleaner and more reliable.
@@BrinkHouse Great Minds think aloke! *(-;*
@@bruce4623 I will say though, the mechanism w handle he swapped to at the end is VERY cool. Great engineering from Adam, as always!
@@BrinkHouse Oh my yes!....
I hated that 1st handle he put on, the 2nd one looks and functions way better!
I've seen rheostat switches for this precise application in both Rockler and Woodcraft's catalog and websites. Still, those solutions don't have the nice mechani-porn feel of something like this. There are German engineers out there who I'm sure are in ecstasy right now having watched this.
This looks amazing! The brass table inset seems to be rotated slightly though, makes me wonder about a possible bending moment on the blade that could make it bind. I'd think of keying the brass into the inset to keep the through-slot aligned.
How complicated do you want the mechanism to be?
Adam: Yes.
I mean, that's about the easiest mechanical way to do it "correctly". That mechanism will easily outlive the bandsaw itself.
@@troy4393 The lever is pushing on the corner of the trigger, the side load will wear out the switch faster. But it probably won't get adjusted constantly so it should be fine. Couldn't hurt to add a timing chain and jackshaft on the other side of the lever, and make the interface to the switch slightly compliant. Maybe an anti-backlash mechanism for high speed adjusting. Definitely need an absolute RPM gauge on the dial, so add in a tensioner, and cam to account for the non-linearity of the switch. Maybe quantize the dial to integer speed values using a cog and magnets, but there are times when you'd want to turn that off so use an electromagnet instead. Half RPMs would be cool so you could add a hall sensor and shift register. Might as well add another electromagnet and make it into an induction motor, and add a microstepper driver to get thousandths of an RPM and CNC control. Don't forget the cameras and cloud services and AI to set ideal speed automatically based on material type, operator mood, and how close to Friday it is
@@alakani You point about the switch is actually a legitimate concern, some switch assemblies are shoddy enough for that to be a problem. I've had to fix this model a few times for non-switch related reasons; it can take any reasonable side loading without issue.
True engineer....had he wired in a fan rheostat as the switch he’d have just gotten the speed control for free.
@@gritnix I know, Adam has said electronics isn't his strong suit. If it was me, I'd have taken that thing apart and reverse engineered the trigger and replaced it with a rheostat/pot. I'd still have a separate switch though so that it 'remembers' the last speed it was set to.
It was a great idea to have an immediate followup upgrade video. I often design and build something and immediately decide to upgrade or radically rethink the design. Which is a great angle for engineering and design, as everything can be tinkered into greater aesthetic, efficiency and ease of use. It's very different from painting (especially abstract), where having sensing that something is complete is essential and often a struggle. Which is still true here, but to a lesser degree lol
I love the sacrificial bits you use when cutting your wood. Finish matters even on parts no one else will ever see. Pride of craftsmanship.
What is very satisfying about this is how he needed about twelve tools and machines, and maybe thirty items and materials, and bing bang boom, he has them all immediately to hand, even for adjustments on the fly. Booyah.
I would prevent the handle from turning all the way up, so that you only turn it "off" using the actual switch.
no there is also a switch. you should watch the first part again
@@1BigBen Yes, my point is that you should only be able to turn it off properly with that switch.
An aluminum tube a few inches long (or as long as it needs to be) above the square nut on the threaded shaft would prevent it from raising too high as you crank it. That’s my first thought.
@@Alex-nl5cy why its an extra step of safty, you dont want that switch getting hit by mistake and turning it on he has an extra step of redundancy of safty
I totally agree that you shouldn't be able to turn it off with the speed control, but you'd have to get it really precise to not end up limiting how slow it can go, because it looks like there's some really fine speed adjustment that happens on the low end.
brilliant on the speed control! Could you give a 2 year review? Love your work and mindset. It gives me so many ideas and I see the world of creating in a different light with your generous content and time. Thanks!
I'm glad you changed the handle, it works much better and looks better, great mod.
Adam Savage: *uses an expensive Festool jigsaw*
Also Adam Savage: *doesnt use it's legendary dust collection, and just air-blasts dust all over his shop*
;)
Right! The dust collection is why you buy festool.
I had wanted to do this for some time. Thanks to Adam for showing me how easy the new table can be, and also thanks for showing me one way NOT to do the electrical/variable speed.
that's THE most bunkers speed control anything I have ever seen, a thing of beauty
So glad you took off the sharp corner, that really jumped out at me. If/when you find that one thing you need to cut that the speed handle gets in the way of I look forward to part 3, worm drive speed adjustment. Do more of these, that was way better than buying a swag offroad table and foot switch and I loved every minute.
Maybe I'm missing something, but couldn't Adam have removed the switch and just wired in a potentiometer to do the same thing?
wiring in a potentiatometer would require a bit of testing to dial in the high/low voltage. I imagine a mechanic answer is merely more suited to Adam's way of building.
Was just about to comment that, but he may not want to disassemble it for warranty or something
That's what I thought too, but everyone is different in the way they tackle a problem an come up with different solutions. The good thing is that either solution works but one is more complex than the other.
i dont think he wanted to alter the tool itself
The trigger also switches mains, it may not be possible to modify it safely.
In addition many people are more comfortable and proficient in mechanical problem solving than electrical. Whatever works right?
Watching the engineering of the speed control has been the most fascinating thing I've seen on a one day build in a while. Loved it!
I made a version of this a few months ago but I wanted it to be easy to take the saw out to use it as normal. My saw drops into a wooden stand, then the steel table I made has the slot in the opposite direction so it just slides into place and secures with one screw, speed control is a wheel on the saw.
Dear Adam, I have to say that lately I haven't felt much like making much of anything at all because of covid19. But I look forward to your one day videos every night after work. It's so relaxing to watch your work even if I am currently un inspired! Please keep up the amazing work and being the awesome maker that you are in these trying times!
Great job. I was super nervous about how casual you were about the moving blade. Glad you like how it turned out!
I vote for a re-do. The rear support for the bandsaw should also be the pivot point for the speed control. KISS!
not just look like a professional there, you actually are professional.
What a difference in the smooth operation with the new crank. Nice mod.
upgrade part 794, you could add 2 stop nuts to the big screw top/bottom to act as stops so you cant wind/unwind it too much, drill some grub screws into the nuts to stop them moving.
Why didn't you just use the speed dial on the saw?
yea was thinking the same. not sure if that might be a mechanical one, so relocating wouldn't work. if not, yea why not just relocate that one.....
For one thing, because it is in a really inconvenient position.
For another, I think that it is an adjustment for the trigger travel, not the speed of the motor. By adjusting the travel of the trigger, you get variable speed, but in a less technical (electronic/expensive) way
@@woodworkerroyer8497 That is 100% a speed control dial. Since the badsaw is portable and you are going to be holding it above your head or pressing your weight into it you can use your complete strength/grip and just adjust the speed controller dial for the desired RPM. This mechanical knob solution is cool but he also took away from usable table space and now has limited his ability for cutting certain material on the table. I think he is going to revisit this in the future as it will undoubtedly get in his way.
@@CodyYankey I'm surprised he didn't try hooking up a variac or some other type of AC variable speed controller. ... I presume it was because of the electronics inside... But a quick snip snip and his favourite wire-nuts?
why yall worried? You're literally never ever gonna come in contact with the tool?? It works for him, it literally doesnt have to work for anyone else
Awesome upgrades to your Mini Bandsaw , Adam !!!!!!!!!!!!!!!
So glad to see you're finally covering that switch! Have you ever thought about being safe and actually doing the box in GROUNDED METAL? Sheesh! Also advisable to bond the tool and bed together to ground. Even if it's double insulated, you've modified it now and leave it plugged in all the time. It wasn't designed for that.
Also, I know you have a passion for wire nuts, and that might be ok for a prototype, but when you have a machine with lots of vibration and moving parts, it's really not an advisable to use wire nuts. Use a vibration rated connector or crimp those babies. A loose wire that's not quite disconnected is what gets hot and starts a fire.
Bought a van w owner installed house power line in it ,had my electrician go thru it all before I touched it, thank God. 3 nuts were totally off and all the other 20+ nuts the guy used were loose, idiot used house parts for a vibrating, bouncing van. Probably the only thing saved it from sparking and catching fire is it's an aluminum van!!
quality editing with the sound on the jigsaw cut. excellent build touch ups
33:34 Lil thwacker making an appearance
This was lots of fun and an excellent result. Yes, it could have been much simpler, but Adam clearly had the parts, enjoyed the small amount of extra work and loved the final result. That's a whole lot of win in my book. I mean, 90% of DIY is doing things that aren't strictly necessary.
Adam never ever say u finished a project on new tools because I know u enjoy every moment of always improving u tools of trade
When you started turning it for the first time I held my breath and waited for the ensuing accident. Glad you’re okay!
"A little hingie-poo.." 😂
Brilliant ! I loved watching the whole process
The sound editing on the table saw montage is great.
Hey wow a TV star that's really down to earth, cool! Didn't know he had his own DIY channel.
I love that if he makes an error, he keeps it in the video and tells us about it.
Consider putting in a chip tray. Helps with collection and clean up. Love the speed control.
this is great. i want to see part three.
some ideas:
recessed pocket for a flush mounted plexi cover for the trigger mechanism
little weight in the bottom for some stability
a nut or two on the bottom of the 1/2 inch thread to stop you from over turning hte speed lever and putting undo strain on the trigger/trigger mechanism
round corners
potentially a nut on the top of the thread so there's only one way to turn it off.
recess the thrust washers into the table top and bottom just a little ( absolutely useless but cool)
and finally:
paint the wood, gunblack the metal, and weather the whole thing.
37:37 and onwards the video was just frighting, I thought for sure he was going to mess up his forearm.
Glad to see your finger is healing up!
33:40 Handle: I was here all the time, watch me.
I just started watching The Expanse ... Go Adam...good job
I think I'd have (at least tried) to do that with an eccentric cam on a shaft that went through the finger hole, but I do love the crank he ended up with!
I'm stealing this idea. Thanks Adam!
Hi Adam, you could make flat pack kits so makers could modify their own band saws. Such a cool mod. Thanks Vincent
That was pretty brilliant. Nice job.
When he said he'd be adding a speed control, I expected him to add a seperate electrical device with a proper control knob and fit it to the side somewhere safe, not this complex mechanical system to preserve use of the inbuilt trigger.
Not trying to be a jerk, what he made works, and I can understand wanting to keep the tool intact. Just not my expectation.
What you had in mind is something Jamie would build. Not Adam. Adam always has the tendency to over build stuff XD
That is hardly a complex mechanical control.
Ale x it’s more complex than necessary
I made a table prob 10 years ago .: 2 things I’ve never needed slower than full speed .. also you can only cut 5inch before it hits the back of the saw. Except for the right side you can cut forever .. but that is where you put your handle.
Nice! I just built my own. I used a switched receptacle in an exterior box myself.
Ah, the benefits of hoarding! haha
great video Adam great build love the long videos keep them coming
Nice!
I think when I do mine I'm gonna sub the crank mechanism for a series of notches I can just manually move the lever into and out of for different speed settings. It will limit how finely I can adjust the variable speed but simplify the build considerably
33:53 beautiful shot
This table is great. I have a swag offeoad table for my portaband which give me miter gauge slots and lets me take the portaband out quickly when i dont want it in the table. Just need to figure out a speed control like Adam did.
Fantastic mod and definitely an improvement! Also love when you finish a build and then soon after you think of ways to improve it. Great stuff.
Very nice mech for the speed control
Finally… a big enough polymer glue dispenser.! I bought some. Thanks.
I didn’t know you could fire nails into 1/8 inch ply. Again. Thanks.
The knob is a nice touch. Cherry on top 👌
I Love it! I want to make one now with my cheap Wen portable band saw. Thanks for sharing adam👍 ive always Loved your ingenuity and plan to tackle projects like these. You have such a Brilliant mind and Could literally Build Anything!!! I dont think theres a single thing you couldnt overcome and build. You simply amaze me with everything you make or mod etc. Thanks so much Adam for sharing and being such a big Mentor in my life and givng me amazing ideas and So much motivation to get out there and just build Something! Anything. Take care Buddy and Thanks so much again.

Id Love to see more videos like this. Like making mods to make tools better. I Love the complex and sometimes simple ideas that really make tools way better!
Alternate idea, Weld the handle to a hose clamp around the trigger and through a hole in the side, that keeps the bed free of any obstructions, and should get you much the same kind of action.
You get to have all the fun. I work for a State agency and can't modify a tool in any way. Especially in ways that void the warranty LOL
I personally would have drilled and taped a hole in the top, with the bolt run to a leaver, but this is a more elegant solution.
That’s a thing of beauty especially with the new handle :)
You're a madman Adam
Great build! Only thing I would have done different is put the fulcrum on the other side of the saw so turning the knob clockwise increases speed, being more intuitive. Another bonus would be a simple foot switch for easy “no hand” operation.
who else was like ADAM nooooooooooo, when he kept moving around at the end
Thanks for the video, I always learn some great tips watching you build.
"Hingypoo" made me smile :)
I was just about to suggest you change out the handle and the nylon washers, but it looks like you have already, and for the type of handle I had in mind too.
Hey Adam, could you walk us through your shop air setup at some point? How you have the compressor set up and have the hoses run for easy access?
I'm only about a quarter way through, but what about a dial dimmer switch on the speed controller?
Considering how much it moved around with the first handle, you might want to get some kind of way to clamp it to a surface in there, and maybe put an emergency cut-off somewhere in there as well. Even with the added weight, it makes me a little nervous.
you could use a D shape pic of steel and attached to a knob and each turn it to push the trigger deep
nice build love watching those one day builds
I would also use shrink tubing on those expose contacts for addition safety
but that would make taking the bandsaw out of table for maintenance a pain in the butt
1BigBen not on the wire nuts. On the exposed taps on the switch that are not being used and any expose wire on the connectors. The connectors can be remove easily
@@maddog48froggy well it is boxed off, but I would just used the fully Insulated crimp connector plug them on vs heat shrinking it
Love your design. Thanks for sharing.
Bill
Would look really cool if you could put a L-shaped hinged door on the sides or something to hide away the exposed bottom. Not sure if it would be feasible for still replacing the bands easily though.
Dimmer switch instead of rocker switch could have saved a lot of time but nice Adam. Love the builds
Hope you do a space build soon. I am excited for SpaceX. Btw love your vids Adam.
Beautiful build. Just one question. Why not use a sewing machine pedal as the speed control. You could then keep both hands on the work while adjusting the speed.
I was screaming to myself, variable speed switch. Then I thought, he may not have one. Maybe for a future build?
Great Adam. I was really losing faith in ya, until the end of this video. Turned out nice. 👍
Hope your well, you been coughing a bit.stay safe.thank you for nice contents
Keep wondering if a recessed speed dial on the side would have been better/simpler. By just turning a cam on the trigger. And leaving the table top clear of obstructions ?
Love metal work on a Lathe.
the saw already has variable speed control wheel by the handle
now i want to see him using it
Not to take away from your build, but SWAG OffRoad makes one, with a foot pedal. Pretty slick unit.
34:36 I would have put the hinge in the middle of the variable speed flap for more coarse tuning, but having finer tuning could be important also. Either way this is a phenomenal design IMO.
@Adam I love that you are using festool, never saw you using this before. What do you think of it? Personally I think festool are the best power tools ever... I own a lot of them...
I collect old sewing machines and use the foot pedals for speed control on my tools . all I have to step on the pedal . easy peasy
Hey Mr Savage.. if you haven't yet.. please set up some sort of gear mechanism so the speed adjustment is on the side. Thank you.
This is amazing Adam!!!!
Dont forget a indicator of what speed you left it at for turning on or a note saying to slow down befor every use no repeats of finger adam
watching the time lapse of you cutting the wood for the switch cover with the saw sound continuing in the background was unnerving as heck.
Like this shot, see what im doing... Pool ball blocker.
I'm noticing transitions in your videos Adam! Looks good!
Adam could have built the speed control by using springs in a fulcrum type arrangement, eliminating some of the complex mechanisims in his design. Instead of applying pressure when turning the crank, you are releiving tension.
Dewalt makes very nice tools for the money
Nice job.
What about debrie and dust collection. A guide with bearings
