Hello everyone,

As with many members on here, I figure I should document my (slow) cafe racer build and maybe get your guys opinion along the way on a few things. I love getting inspiration from others builds and a lot of the things that I do to my bike come from other great members out there.

First a little back story: For as long as I can remember I've always wanted a motorcycle, but never had the money to get one. Last year I was searching the web when this 1980 cx500 custom caught my eye. What a cool looking bike I thought. Long story short I went and picked up my first ever bike and I was so happy. Got it for $250, and knew I had lots to do, starting off with replacing the stator. (Also the PO did not have the ownership and it was an american bike....that took a while to get worked out lol) Fixed it up and it ran great after a little tuning. At that point in time i just wanted to have a bike to ride so I didn't do much to make it look pretty, but now that i have a bit of extra cash (I don't really lol) I want to get it running better and looking fantastic.

I like the tray, you can shape it with compartments to fit different wrenches and a set of plugs.
JIS screwdriver, metric wrenches in sizes from 9mm to 17mm. It also includes the spanner for the shocks on the Custom and Standard.

...metric wrenches in sizes from 9mm to 17mm...
But not every size in that range. My Standard uses 8, 10, 12, 14, and 17mm. Spark plug socket is a 16mm, I think.

Ooooo I like that thought too, making custom holders for the wrenches! I wish I had a bit more space in there, that's really the only limiting factor for how many things I can put on the bike.
Now that you guys have listed all these great things, I may need to take a look see at the bottom of the electrical pan and see what I can throw under there. Maybe design a custom case that locks into place on the bike and is low profile enough to not notice...........I think I have my next project :eagerness:

Ha! Ha!
I was just going from memory, not with it in front of me!

So school is finally finishing up for me, which means the next three weeks or so will be brutal with projects and exams, so not much will get done on the bike. But I wanted to show off the hump drawer now that it is ready to go.

Freshly printed out in PLA this time as it won't get as hot as the hump being that it is not in direct sunlight. It will still withstand heat up to 200°C though so I don't think deforming will be an issue.





I wanted to add a bit of color to make it pop, so I taped off the area around the letters:



Then shot it with a few coats of red paint, sanded down as best I could to get the letters crisp, and gave it a few coats of clear. A nice wetsand and polish and here she is, almost ready to be mounted on the bike:



The last step was to add a little pull tab to the bottom to grab onto, and also add some fabric on the bottom so it slides in and out nice as well as dampens it so it doesn't rattle around:



A nice and snug fit on the bike:



So now I have a few compartments for smaller components like fuses, string, tape, meds and spark plugs. Next step is to buy all the components for a "full" tool kit and work on modelling the case that will hold those! Sadly, like I mentioned at the beginning, that might not happen for a few weeks :(

Well now that school is done, life seems busier than ever! I have been super busy looking for jobs, helping out around the house and spending time with the family. I haven't had much time to work on the bike, and just enjoy a few hours here and there riding it.

Unfortunately, right now the bike is out of commission again due to another electrical failure causing the left side to lose spark. I have sent the Rae-San unit back to Ray for repairs, but likely won't have it back for a while. I am also waiting for the old Ignitech to be repaired as well, so the bike sits in the garage for now. I was hoping to get a spot on the ignitech group buy, just to have a spare, but looks like I might've been too late for that.
So if anyone in Canada has an extra Ignitech unit that they are willing to part with, let me know! :D

In regards to the bike tool case I am making, I have bought almost all the tools I plan on putting on the bike, and have begun modelling a rough design. However, it has been a real challenge so far due to the odd shape under the seat, and the various things protruding from the bottom (bolt ends, the regulator, tire guard and tire, etc...). So I have to design around those things, all while ensuring the case is easy to remove and fastens securely. This is probably the hardest thing I have yet to make for the bike surprisingly haha.

This is what I have at the moment. Lots of changes to be made though, including reducing the tire gap in the rear, figuring out mounting points and mounts for all the tools, etc... but you get the general idea and shape.





I will continue to work on it slowly, and will update you guys if anything really interesting comes up.

Maybe if you kindly ask Kameron to borrow his spare Ignitech until the end of riding season and offer him ciders of his choice, he just may sway in your favour. ;)Long story short, I have been using his at the moment due to testing, but if he does give you the green light and is not planning to use it in the next month or so, I can remove his to lend you, and I can swap mine back in...
 
#935 ·
You guys really are the best! That's very kind of both of you, and I think I might take you up on the offer Kameron. I sent you a PM just now.

Thanks again for all the help, you guys are lifesavers! :D
 
#936 ·
So a big thank you to Kameron and Chocolatelvis for helping me get back on the road! I can enjoy the cooler weather now that fall is upon us and ride until the snow hits. :D

The 3D modelling is coming along nicely, but super slow as usual haha. I made a few changes to the tool case including reducing the space for the tire, modifying the fit slightly and starting to add the details to hold the tools in place.
I decided I will attach the tool box to the bottom of my bike with a large thumb wheel in the middle and a support system on one or both ends. I will of course use an actual metal nut pressed into the 3D printed part to ensure a tight lock.



Then I got to work modeling the spot for the wrenches to go. I decided to make the holder removable from the main case, just so if anything changed I would be able to reprint or fix the one piece rather than the whole case. It's a simple slot design to hold the wrenches in, but should work nicely hopefully.



Here is the end view of the wrench holder, you can see it is a separate piece with a little latch to keep it locked down in the case. The slots themselves are tapered so that the wrenches should stay pressed against the bottom and not rattle around.



That's all I have done for now, the next step is to model the holders for the rest of the tools and the rest of the mounting system.

Still plugging away at the tool kit slowly. The bike is running fantastic though and I am so happy to be able to ride the season out!!! :D

I have almost completed the 3D model for the tool kit. Just need to make a mount for some needle nose pliers, and then split the took kit apart so it can fit on my 3D printer bed. I plan on reinforcing the whole thing with aluminum rods which I will slide in at the piece joints. Here is another render of where I am at. You can see a lot of different cutouts and slots, but it's too hard to explain what each one is for, so instead you'll just have to wait and see haha.



And as some of you might know, we have the Phototag thread going on right now. The last tag was a picture of you riding your bike, and since I didn't have a cameraman handy, I had to take a video and then grab a screenshot. The video ended up being pretty fun to watch though, and I posted it on that thread. I figure I would post it on here too so you guys can really hear what the bike sounds like driving down the road. Let me know what you think!

So while I keep myself busy with job searching and trying to finish this toolkit thingy, I needed a little side project, just to get my mind working in a different direction. This lead me to realize how keys are one of the more overlooked things in peoples builds. Looking at the key on my bike, it reminded me of a sword. So running with this thought I found my next little project!

First step was 3D modelling the sword handle. I just went with what I felt looked good, and used some reference pictures from online. I made a cutout in the back of each half so that the key would be secure in the handle.



I then printed out the handle halves, removed the original plastic part on the key, and cut the key to match the cutouts I made in the handle.



Next step was attaching the key and handle together, which I accomplished with JB weld for a secure and long lasting hold. Then it was time to paint, so I masked off the key portion.



And then I went to town painting it. As stated before, I do not claim to be a good painter, but I did build a lot of scale models in my younger days, so I had some skill with distressing the handle to make it look worn. I also wanted to add a touch of red, to match the bike, so I wrapped the handle in red thread and did my best to distress that as well. All in all I think it turned out really neat! Some people will say it's dumb, or wonder why I did it. I just say I did it because I could :p And if I grow tired of it, I've always got spares!

This is the kind of foresight I wish I had lol :sulkiness:
You raise a very good point, and one that I wish I had thought of back when I had access to the tools needed to make them. Now I just have to hope I don't ever drop the bike, or be prepared for the nightmare of making another one. Or go back to the normal signals, but what fun is that :p

Man, reading through this build thread, I feel like a complete amateur. My build has no machined parts, everything was as my dad put it; "hammered and filed to fit". I did all my fabrication with angle grinders, cutting torches, a flux welder (or as I like to call it, "Mister Spatter"), files, a BFH, a drill press, taps, dies, etc. But nothing with precision. Nothing ever precise, more of a "mock it up, weld something, see if it fits, grind it a bit, repeat until it looks okay". Nothing with a plan, just an idea that I finagled into a workable solution with time and patience and constantly changing ideas.

But you've created a wonderfully polished, factory-finished machine. I thought mine was pretty good, that the blemishes were hidden or not readily apparent... but yours is better than a factory ride, it's better than most bikes out there. And I've been doing this for years, it sounds like you're still in school! Good show, sir! Good show!

Charles.

Love the key :) I love to see people make unique items that make the bike "theirs", regardless if its 3D printed, CAD milled or whacked out with a big hammer and some duct tape. We all have different skill levels at fabrication and differing amounts of "tool access", but anything you do just makes the bike more "yours". Love seeing some of the great ideas and creations here, as it just kick-starts my brain with ideas as well, keeping the big "circle of ideas" flowing :)
 
#948 ·
Thanks for the kind words you guys! And thanks for the compliments on my "skills" ChopperCharles, that means a lot coming from a legend like you! When I first started doing research on these bikes, your name and bike was one of the first that I saw. In my mind, I thought you did an amazing job making everything look complete and professional, while I look at mine and still see tons of things I want to fix :p And for your new build, I know your "hammered and filed to fit" philosophy will produce another fantastic looking build!

I may have the youthful spirit, but the experience you guys have will take me years and years to attain! That's why I love how people can take whatever skills they have and make an amazing and unique machine. Like Stern said, regardless of what is used I love seeing peoples character transferred to their bikes :)

Well after a long battle of modeling and tweaking the design to get everything to fit, I finally have the tool box designed to the best of my ability. I added places for the last few tools and made a few adjustments to the mounting points. Here is the final render:



The last step before 3D printing was to divide the component up so it would fit on my print bed. Dividing it into 2 sections was sufficient, and it is reinforced with a 1/4" aluminum rod running along the bottom of both pieces
There were some big overhanging sections, so some parts of the print are rough and will need to be sanded down, but I plan on painting the outside surface anyways so it isn't that big of a deal right now.

Top and bottom views of the 2 main sections:





And lastly the two hand wingnuts, the wrench tray and Allen key holder:



After some initial tests, most of the tools fit nicely into their respective places, but some spots are too tight, so I used a heat gun to soften the plastic just enough to form a secure hold. Slowly coming along!

Also, I just noticed this thread has reached 200,000 views!!!!!! :eek:
Thank you all for your continued interest in my build! Although it seems like I always have something else to work on and the bike will never be fully complete, I appreciate all the feedback and support! I hope you guys will continue to enjoy whatever little project I start next :D

No disrespect towards the goldwing lol, that is a great bike that has stood the test of time! Just saying it's a bit larger of a bike compared to the cx series is all. I would still love to work on a goldwing!
