- I modified a Chapman guitar for our friend Rob Scallon. This unique build allows Rob to stretch just a single guitar string to make some beautiful music. I had to figure out the mechanism, the fit, and the adjustability for this custom B Bender guitar. Check out Rob's video:

The concept behind this custom B Bender guitar is to pull the B string mechanically up a full or half step without affecting the other strings. There are a few existing designs to accomplish this, but I felt like a mechanical linkage made out of metal would be the most reliable and consistent. The difficult part of putting these hinged elements together was making sure that all of the mechanism could fit inside the guitar without completely destroying it.
The Chapman guitar we were sent for this project was a Telecaster style, which allowed the strap nut lever to move freely. The tummy scoop on the back presented some challenges when placing the B Bender assembly. I wanted to avoid any contour cut or beveled surface because it would be more difficult to route out the cavity. After making a template of the guitar on a scrap piece of plywood and redesigning the linkage, I had a design that would work.
Using some scrap metal rod and flat bar stock, I cut and drilled slots and pin holes to connect the S-shaped mechanism. The screws that would act as pivot points were also used to connect the assembly to the guitar cavity. To counteract the force of gravity pulling the guitar down, and to reset the guitar upward when the player pulls the B Bender down, I had to strategically place a heavy spring alongside the linkage. Once all of this was working well on the plywood, it was time to carve a hole into that beautiful Chapman guitar.
The B Bender linkage was ready to be installed in the guitar, but I first had to cut into the back in just the right place. To make the cleanest cut I could, I chose to use the router with a guide bushing and a template. To make the template, I took a photo of the plywood mock-up and outlined it's confines. I then took this photo into Adobe Illustrator and traced the outline. Using this vector graphic, I cut a template out of clear acrylic on the Glowforge laser cutter.
Because I was using a router bushing, I had to offset the template by 1/8" so that the bit cut the exact outline I wanted. This method would give us a perfectly matched hole in the back of the guitar. I also didn't want to cover the mechanism, I think it looks awesome, so I decided to cover it with another piece of clear acrylic. This was actually really easy using the laser cutter. My first vector graphic would be the outline of the photo (this will end up being our cover); then the 1/8" offset I mentioned earlier to account for the router bushing; and lastly another 1/8" offset from the previous one so the router could carve a shallow shelf for the acrylic cover to sit on.
I taped the multi-layered template to the back of the guitar and took out each template as I finished that cut. It worked perfectly. Now it was time to place the B Bender mechanism in place and make sure it all worked.
The process of mounting the assembled linkage in place was pretty straightforward...To Read More Go To iliketomakestuff.com/?p=40715...

Here's Rob's Video: ua-cam.com/video/2k4337pXrtQ/v-deo.html
Thoroughly enjoyed his video, much more than I even thought I would in fact. I think it's worth noting that a good portion of it is an interview discussing the concept in general, as well as this particular application. It had some really good, interesting info that I wasn't expecting.
Really enjoyed the video! Maybe have another strap hanging down to the floor on the back end of the guitar and step on the end to prevent teh guitar from moving up ?
holy don't screw it up
You killed that guitar ... HELL YEAH 😎!
Sawtar, please
Thanks for the guitar Bob :)
Bob and the Team are great people! Looking forward to hearing you play it!
No problem. Lets do it again some time
When’s the video gonna come out Rob?
Thanks for giving us a private concert.
Bob and Rob - best "crossover" ever...
"And we'll put off cutting the hole as long as possible."
"So now we're just going to remake all these pieces."
I so hear you, Bob! It turned out great!
It was pretty daunting
Hmmm timezones
@@percival743 Hmmm Patreon early access. ;)
@@FigmentsMade oh
Now buid a bass that slaps davie504 back.
Haha
Lol. Epic
That sounds more like a Simone Giertz type project!
@@lastralla good call. I'd like to see that happen.
@@lastralla or Michael Reeves'
Missed opportunity for a "Fender Bender" :D
Hiren Makkan Too late, that’s what some of the country guys call it.
Ba dum Tsss
I don't have a musical bone in my body, but as always I was amazed by the engineering and quick adjustments you guys make on the fly. Another great build Bob!
Thanks!
Ya... That has to be, aside from cutting out a wall in one's house, the most terrifying project one could do.
Well done Bob! You sir are a master.
That's why it was put off for 2 years.
Nice you got first comment
And yea, I can't imagine how terrifying this must have been to do lol
Hmmm timezones
My favorite collabs on UA-cam to see are bob & rob!
I really liked you showing all the iterations and changes you had to make. Very honest and true prototyping! Great work!
It's great to see you doing projects like this. Definitely helps me get over my worries when starting a challenging project.
It just took me 2 years to gain the courage to do it :)
prototype building 101, a perfect tutorial in how prototypers struggle with their projects. i get a conny bloom feeling, electric boys, when hearing the music, he even played with hanoi rocks.
yep. gotta change that, that, and that.
I would label this as what not to do for prototyping, but yeah, always things need to change. I would wait to build the functional prototype until you have the basic geometry figured out. Maybe build a cardboard mockup and save yourself many hours of actually making parts until you're ready.
This was absolutely beautiful. The progression of the design all the way to Rob’s video and his progression for finding the music this instrument should play. Truly awesome!!
Cool project Bob, thanks. I like the way you and Jimmy solve complex problems with a simple approach.
Dude. That was a really interesting project. Never knew something like that was a possibility. Watching Rob's video right now.
I've REALLY been looking forward to this video since you started talking about it and man, Bob!, what a great job! One of my favorite videos of yours to date (and I've been following for YEARS!)!!
Thanks! It was terrifying, but it turned out great!
That was awesome. Thx for sharing
Really cool Bob, awesome stuff! 😃👍🏻👊🏻
I remember first hearing about this on your podcast. Glad to see it come to life! It is awesome!
Thanks, it was a lot of fun!
We waited so long... and it was worth it!
Bob. I love your videos but watching this one and Rob's video was AMAZING. Thank you sir.
Oh my God i waited so long for this Type of Video from two so nice guys!!
As a fellow guitar player, I applaud you for working up the courage to cut into a Chapman. You are a braver man than I.
Amazing build and the thinking it took to make this work. Thank you for showing the trials showing that there was so much that goes into making something with no plans. Simply amazing. great job and keep on Making cool stuff.
That's insane! Really cool process. Now to go hear how it sounds in Rob's video
I made an audible gasp when I realized that the acrylic was clear and not white. Glad you didn't paint the inside and kept it pure. Well done!
Robs smile is always contagious
Exelent tutorial. I wouldn't be scared off by all the fancy tools. It can be done with a lot less but its great.
I'd say that that was over the top engineering Bob! Great work & now I have to go watch Rob's video to see how it all worked out & how the guitar sounds....... 👍👍🎸🎸🎸🎸👍👍
Man, you are a brilliant builder. Been watching your vids for a good while now, and this one is just crazy cool. R2D2 was pretty bad ass as well. Plenty of inspiration to push to yourself to do whatever you dream of. Keep up the great work!
Literally my two favorite people on UA-cam in the same video is a win/win scenario
Yes ! YES ! THIS IS THE KIND OF CONTENT I'M LIVING FOR
Man your awesome! So glad I found your channel through Rob's!
Great content Bob and Rob! Love seeing you work your magic on musical instruments. Now I gotta go back and watch your other guitar vid haha.
Hi Bob, great work!!! I enjoy your videos, but with this one i've enjoyed more 👍
This is great. I can't wait to see what you come up with when you get the mill up and running.
Awesome video! These 2 years waiting was worth it!
wow, this is incredible!! I've never actually seen a b bender let alone how to mod a guitar to be one. Really amazing work!!
Awesome Build Man 👍👍🎶🎶🎸
You killed that guitar... Hell yeah!🎸👍
Crossover I didn't expect, but am glad happened!
From bob to rob,awesome
Awesome Job! Bravo
Super cool! I made a double bender a few years ago that does the G on the strap and the B on a pull that attaches to your belt with a carabiner. The B goes up a full step when you move the guitar away from you.
Also managed to hide it all within the guitar so it’s 100% hidden. Guitar looks stock!
Wow!!! That is awesome!!
Before I'd seen this I'd done some *very* cursory reading on the B bender (I think it started with a video with Marty Stewart in it and went from there) and it occurs to me that the Chapman T type, while a great guitar and the right body type at first glance (I also know Rob is a signature artist so it's only natural), made this build a lot harder. A regular Tele is essentially a cutting board with two pickups, so none of the contouring is there, meaning apart from the string placement, there's lot more tolerance.
Really cool build though, and the ways you literally got around the issues were really inventive and the video on Rob's channel shows how well it turned out!
I’ve been watching so many custom guitar videos, but I dint expect to stumble onto an ILTMS vid!
Outstanding work brother!
i actually saw the Rob video before yours but .. you did absolutely well .. wowo .. well done Bob
sounds amazing!!
Great job.
Now that looked like it needed a lot of planning!! Great work 👍
Not gonna lie… I got more than a tad anxious as you started routing the body of that guitar! But man, you did an incredible job! Bravo!!
YOU THE MAN BOB!
Very good work. Considering that the spring has to have so much force to support the weight of the guitar itself and that you don't change the pitch every millisecond. Cool
Amazing job, dude.
I've built a couple guitars in the past, and I've never fucked around with this kind of mechanism, since I'm afraid of messing up my pride and joy. You, sir, are braver than me!
Beautiful work. Making me want a b-bender again. And I had no idea the Chapmans were so chambered.
Trick I've been seeing is putting tape on both the template and body, and super glueing the tape together. Solid, cleaner, and easy to remove when done.
Thanks! Honestly, I had no idea they were chambered either :) That was a big suprise once I started routing !
Awesome B Bender Guitar !!!!!!!!!!
Great video
Wow! Freaking awesome, dude! Probably spent forever stressing about doing that and it turned out great! Impressed I am, young maker.
your commentator like a teacher to us👍🏻👍🏻
Hey bob, big fan. I like how you figure things out. Even though you make mistakes, and that's ok. As long as you are learning. That's how we learn, am I right. Great job, well done.
Thank you! I really appreciate that!!
I feel my two worlds are colliding....I like to make stuff and stringbenders. This is the perfect video!
This is impressive engineering...but the real challenge was the cutting of that beautiful guitar. Nice work!
7:01 "If I had a mill this would be a lot more exact and a lot easier"
Dude, didn't you just buy a giant mill? 😄
Yeah, 2 months after I made this :)
@@Iliketomakestuff time is a merely a construct in the world of a UA-camr's release schedule
I appreciate that you did it without a mill. Not sure I will ever make a B-bender, but after watching this, I think I could. I don’t have a welder so I would have to work around that. Still pretty intimidating but you proved that it could be done. I’d try it on a Craigslist Squier. Lol.
Well now I feel stupid for not scrolling before my commen
@@jljmonky And a giant lathe! But time is an illusion.
I can’t believe you fabricated all of that. I was expecting a kit of some sort. Great job.
I own a gene Parsons b bender on a telecaster and from all the research ive done he is the common maker but he refuses to sell kits because too many guitars have been ruined by inexperienced people trying it. Really impressive he was able to fabricate it all.
I like he casually redoing everything.
Hi Bob, guitar turned out beautiful. If I may suggest since I work on guitars full time, you can use a down cut spiral bit to router out the first 1/32-1/16" to minimize any finish or wood chips on the surface. Thanks for making these videos.
What a treat! Two of my most favorite men on yt in one video :D You mates just made my day
Amazing job for a nerve wracking project
Thanks!
A suggestion in place of the aluminum bar could also be sleeve nuts with right & left handed all thread stock. That would allow adjustment of the tension on the rods. I know not everyone has something like this in their shop but it can give individuals better ability to tune the mechanism.
Most anticipated crossover in all of history!
This is really sick dude, nice job
Thanks so much!
I once turned an expensive B.C. Rich Warlock into what was the world's most expensive piece of kindling by using pressure to bend once. I cracked the neck mount in a way it literally splintered the wood and could not be repaired. If I knew about this mod back then....I would still be playing that beautiful piece of work. Thank you for sharing this.
Ouch
I can imagine that would be terrifying to cut into a good guitar. Really cool build. Heading over to check how it sounds.👍
YES, THE COLAB OF MY DREAMS
Oh boy, so pressure with this project! :D
you should have seen my face looking for the router approaching the guitar :D
Very nice job it's amazing.
Just came from Rob's video... this thing turned out great.
Awesome result. The only further thing to make would be to 3D print a channel cover where the strap lock to slide within so it looks 100% stock and covers the exposed inner body, it would take it to another level and it also might prevent the lock sticking. 👍🏼
Great work Bob, is amazing, this guitar is for exhibition only.
By the way, I remember the folding guitar stand and I could never see the template to build it, is there still? Thanks for share so much stuff!
Manual tapping - respect!
More guitar videos!!
So cool
Bob doing this mod to a Chapman for Rob Scallon is the most ambitious crossover in history
Aren't the aluminum linkage and the steel strap piece being together facilitate rust?
I'm wondering if you could use something like a bicycle brake cable and a floor peddle. It would limit your ability to move but would simplify some of the mechanics and would maybe eliminate the mechanics getting picked up in a recording session like you mentioned. The only other bad thing I can think of is the slop that would be in a brake cable.
My heart goes out to Rob Chapman at this difficult time. R.I.P. lovely Chapman Tele.
Oh man I totally understand why you didn’t want to do this. The sphincter tightening was strong with this one!
Man...you had to redo it so many times. I'm sure that was trying your patience, but it turned out really cool! Also, this had to have been on the Totally Bananas list for a while now.
Wow this is so cool. From the intro I figured ok, he bought a B-bender kit (which I kinda wished you did so I'd know where to get one). But this is so much better!
Hip Shot sells the Parson-Greene......you can also get them on Ebay. WD Music also sells a version that is similar. These require a large rout cavity and a plate on the back. If you want the coolest one look at B&W Benders on Facebook. He doesn't rout the body, its all done internally but will not sell it as a kit. He does the installation. If you are going to do it yourself I suggest buying a Telecaster body from Eden guitars and do it on that body. They are decently made and not too expensive. I have a Fender USA Nashville B Bender that weighed over 10 pounds new. I bought a paulowania body to reduce weight and replaced the steel plate with 1/8" aluminum. It now weighs about 6 pounds....
@@jchavins thanks!
Really cool video made one out of the pieces of a bicycle brake and a flat piece of bar stock and this spring off of a door only drilled 1/2 inch hole behind the bridge I am visually impaired but had to have one did not want to do a bunch of drilling and routing for obvious reasons honestly want to figure out a way to make one that bends the bee and the g using floor pedals
I was wondering how to solve the issue with the straplock, and I thought you need some kind of spring that pushes it back down so it stays in tune. But regular springs wouldn't work, cause they would just be soft in the beginning (where you need the most tension) and hard in the bending mode (where you would need the spring the softest). So now I have the idea of using some kind of pulley system like a compound hunting now, where it is the strongest pull in the beginning, but when you pull it gets lighter and lighter. I think this would be a great idea to improve on the design to make it the perfect b-bender!!!
Deleted my earlier content because I think I misheard something or got it backwards in my brain. Just wanted to say it was a very difficult and cool build that turned out awesome. Thanks for sharing!
I think Teflon washers sandwiching the aluminum strips would help dampen the noise the mechanism makes when plugged in to the amp
You said you made the shovel guitar 3 years ago, and I thought there was no way that could be true...didn't seem that long ago. I went back and looked....wow, I've been following you guys for a long time. It's been a fun ride.
Video must have been recorded a long while back cuz in it you said "if we had a mill", keep up the great work guys
The big ol’ “NOPE” when you tried to catch the metal piece made me snort. 😂
Whoa bro! Thought your process was waaaaay cleaner! Got stuff all over the place.
I liked the way think. Thanks
Superb work, Bob. However, you're a braver man than me to take on this!
wow i'v been reading his name as Rob Scallion for all this time.
turns out he's not named after an onion who new!
I've always known his name doesn't have an i in it but I always subconsciously read it that way lol
