MatosTaco's Build Thread

Still going at the two wheels with epoxy. While waiting for a coat of epoxy to dry, I went ahead and started on the electronics. I purchased some blank PC boards and a bunch of tiny push button switches. I figured the only way I could get dual buttons into the space provided by the front buttons on the IS300 wheel was to go custom like this. I put two buttons on either end of a PCB and soldered them in.

I was happy with this setup, so I cut the PCB down to two separate boards and then cut the remainder into several others. These got buttons soldered to them as well. I actually need to make more as I have several IS wheels I am going to be doing this to.

The next time I do this, I will cut the PCB on a bandsaw for a nicer end product. Not that it matters too much as I plan to 3D print a small housing for each board and fill it with potting. I also took apart the wires that ran to the cruise control stalk in preparation for installing my push button start button. I thought I had more wiring options here, but it would seem that the wires for the base of the cruise control stalk are connected to the wires that go to the button at the end of the stalk. When you move the stalk up or down, you ground the red or the white. Alternatively, if you push the button, you are completing a circuit by connecting the red to the white. That's how they created the different functions of the cruise control stalk.

Part 4 of the carbon fiber/flat bottom steering wheel series is now up

While allowing the epoxy on the steering wheels to harden up for further sanding, I started trying new things with the steering wheel emblems.

First step was to print out a bunch of new ones

Then, I sanded the faces, poured a little acetone on them to smooth them out, and painted the emblem and edges with a silver sharpie (once the acetone had dried)

I also printed a matt with bolts that would allow me to level it for a proper resin pour. It has little circles to raise up the emblems and allow resin to drip off of them.

I overdid it with the torch when removing bubbles on some of them, and that caused the silver to come off and contaminate the resin

Also, I should have made the raised mounts higher. Resin flowed down and bonded these to the matt, you can see I had to break one to remove it. Look at those globs of resin!

Here are the final emblems. On the one I broke, the resin came off intact and with the silver attached to it lol. I will probably spray it black from behind and be able to use it. The others have assorted defects that I will fix on the next run.

Wow dude! Good Stuff

 

Thanks! Hopefully, I will have a finished steering wheel by this weekend.

 

Got the first video done for the SC300 brake master and booster conversion

I got far enough along on my steering wheel project that I needed to get leather for wrapping both wheels. I found someone that sells automotive grade leather in bulk on Ebay, so I ordered almost an entire hide worth of leather. Good Lord does this stuff smell good! Opening that box was like walking into a fine Italian shoe store or climbing into a new Ferrari or something haha. I imagine a woman would inform me that it smells like opening a brand new Gucci purse lol. If I can find a way to dye it to match the grey in my interior, the whole interior is getting wrapped in this stuff! Heck, I might just wrap all the grey in black leather. I literally like it THAT much lol. I will definitely need to buy more leather though.


Best smelling box I have ever opened!

I already went and cut out a leather wrap for one of the wheels

20211012_195929 by Jose, on Flickr


I will have to make a trip to the parent's house so I can get the stitches done on my mom's sewing machine

20211012_195917 by Jose, on Flickr

 

Aside from the leather, I also built this nice little rig so I can work on my steering wheels more easily
20211012_200019 by Jose, on Flickr

Since this particular wheel was already sanded to perfect smoothness, I went ahead and used the rig to help me clearcoat it. I used my HVLP paint gun and some automotive clear. I initially feared that the clear would not be as smooth and lustrous as the epoxy is, but I must say, the finish is absolute perfection!!!

I have never before laid a smoother coat of clear and I fancy myself a pretty decent painter rofl. There are a couple of tiny pinholes, but nothing I can't easily fix.

Hopefully, I can finish filling in the low spots on the back and inside of my other wheel soon. It will look fantastic once clear coated, especially because of the red line I did on this one.

I started off the leather work. Unfortunately, the sewing machine I have access too does not make a wide enough stitch for my needs, so I went with a baseball stitch. I also noticed that the lack of smoothness on some of the surfaces is showing through the leather. I will likely remove it and smooth out these areas somewhat. They are rough because I filled in the gaps in the rubber using spray foam followed by hot glue gun. I got the foam pretty smooth, but the hot glue could stand to be much smoother.

Besides the steering wheel, I have also been working on the brakes in the background. I got them to feel better over successive bleed cycles, but they weren't yet where I needed them to be. However, I found out about this little gadget, the

$71 Power Probe BA10 Small Adapter for Toyota

Power Probe BA10. It locks into a Toyota brake reservoir using three pins and then the center expands in order to seal an o-ring against the inside diameter of the reservoir opening. This allowed me to bleed the system quite well. I have to say, even though I can lock my two front wheels up now, I still don't like the pedal feel. I worry that part of that is the 5/8 bore of the SC cylinder vs the 1" bore of the Tacoma one. Had I remembered that a larger bore causes a stiffer pedal, I would never have gone down the SC master route.

Another thing I started on was getting a proper cooling fan setup. I originally intended to get two fans to mount into the old shroud I had from my failed FAL setup. However, I was able to find a 17" diameter fan with the right thickness to fit the space and a 2400 CFM flow from Derale (model 18217). It was competitively priced vs buying two smaller fans and would leave lots of room for activities... so I got it. I've already tested it by sitting idle after a long test drive with the AC on, and it keeps the truck cool and the AC on Arctic mode lol. It also uses curved blades so it is nice and silent from the interior of the truck.

It's massive! Yet, it's light weight.

Well, I got the leather done and unraveled the masking tape so I could admire the contrasting black of the carbon against the black of the leather. It looked spectacular.

Unfortunately, the upper right hand side showed some imperfections and lumps through the leather.

20211021_104423 by Jose, on Flickr


I ended up removing the leather and smoothing those imperfections using a soldering iron (these were imperfections from hot glue gun that I used to fill in some gouges in the steering wheel rubber)

 

That piece of leather never fit perfectly and was a nightmare to re-stitch, something I attempted twice before giving up and making a whole new piece

20211022_140709 by Jose, on Flickr


You may notice this leather appears a different color, this is because I did shoe polish on the other piece. This one got it after I was done stitching

20211020_223721 by Jose, on Flickr


Here is a mockup with the airbag and buttons, post shoe polish

20211023_120301 by Jose, on Flickr


I then took the buttons and lower airbag cover trim off so I could carbon wrap them. In the meantime, I installed my push start button to see how it would look

I can't wait to get this thing in the truck!

 

I took some time today and wrapped a set of buttons in carbon fiber. I also filled in low spots on the back of the second steering wheel that I am building.

These rear pieces have the button shaved since both buttons will be up front now

These are the front pieces

Messing around with 3D printed buttons revealed that it will be rather difficult to get the proper dimensions for a dual button setup on the front of the steering wheel. I will need to have the button housings 3D scanned so I can modify the design in CAD. That will allow me to create a built in, dual button setup much like the built in single button it comes with. In the meantime, I got tired of waiting, so I assembled the steering wheel and installed it. None of the electrical, save for the horn, will work for the time being. Also, the connectors from the steering column to the clockspring do not match those of the IS300 clockspring (another downer to my 96 vs 98 and later Tacomas.) No biggie, I will just have to take a trip to the junkyard to collect the correct connectors. At the very least, I will be able to enjoy this beauty, and let the wrinkles disappear under the heat of the Florida sun.

Man that looks great your hard work pays! Well Done!!!

 

Thank you! I have to hit you up about the electronics, but I need to go get the connectors that go from the dash to the IS300 clockspring. My 96 Tacoma uses different plugs, so I wasn't able to use that clockspring.
