Re: APL's V4 Cruiser Build.

Now that I have a better idea of how the wiring is going to go, I can order up the switches & parts I'll need, and get the final finishing done. The three air tools I like to use are the 2" angle grinder, a right angle with a spiral wrap, and the legendary Dyna-file. Belts and spirals are 4...

Re: APL's V4 Cruiser Build.

I'm feeling better about it, and anxious to see all this hard work pay off and not fall short like the DIY motor project did. I'll return to that this winter probably, for another round of abuse. The plan is still to run a DIY motor in this bike, but It might take a while. 1kW was the first goal, bu...

Re: APL's V4 Cruiser Build.

I have one side plate fitted, and it came out nice and tight. The 1/2" post's take the lateral stress, and some 1/4" caps will just hold them down. The aluminum color doesn't help visualize, but the plate's will be black, and I think once the whole bike is black, it's badness will emerge. ...

Re: APL's V4 Cruiser Build.

Thanks mxiemming, your frankness is refreshing, and I appreciate it! Youre right about most of that, the blue batteries are hard to see around and I'll be hiding them soon,.. and some black paint will go a long way in toning the bike down. I'm still struggling with the shock set up, and it needs to ...

Re: APL's V4 Cruiser Build.

No, not done, still have a ways to go yet. Thanks for the thumbs up though! Need to get it painted, and go through all the
electrical stuff,.. these are just mock photos, so I can get an idea on what to do next and what to change to get the 'look'
that I'm after.

Re: APL's V4 Cruiser Build.

Finished up the brazing, dip tanked it, and hung most of the parts on it for a couple of pictures before I start finishing it out. It's looking pretty raw, but at least I can finally see it's full form. V4 Back .jpg It doesn't look like I had hoped for, and it's looking a little 'utilitarian' or eve...

Re: Low Speed, High Torque Hub Motor?

To be clear,.. it 'has' to be a in-wheel hub motor? Driving the wheel with an external motor and gearing could easily
achieve all those goals I would think. Just curious.

Re: APL's V4 Cruiser Build.

Good question qwerkus. This eccentric is turning out to be a disappointment, theres a bolt on one side that goes all the way through and is 'supposed' to tighten the two halves together, but the BB cups push the two halves outward when it's tightened. :roll: The solution was going to be a threadless...

Still plodding along,..I hoped to have a lot more done, but life has different ideas. The left motor mount is a lot more involved, with frame inserts and bolt lugs, but I got her done. Left motor mount..jpg Moved on to the axle mounts, and torched out some .250" thick steel washers, milled an 1...

Re: APL's V4 Cruiser Build.

I settled on the idea to use a piece of tubing for the center of the motor mount, and I'll silver braze a 1/4" thick slotted axle mount into it. That way it can be removed/replaced for whatever reason, and makes it easy to align parallel to the motor. I decided to braze in the drive side mount ...

Re: APL's V4 Cruiser Build.

Cut and turned the tube and milled some slots in it for a little flare. Sketched a pattern from the drawing and scribed it out on some 1/8". Added a couple of bridges to give it some body, and brazed it all up. Shell and bracket..jpg Turns out, the shell and the down tube spacings are almost th...

Re: APL's V4 Cruiser Build.

Most of the time is spent just trying to figure out what to do or how to do it. I have everything drawn out, but a lot of times the actual building is subject to change when I get there. The front eccentric BB was going to get brazed directly to the frame, but I opted for a bolt-on idea that will al...

Re: DIY Toroidal Axial Flux PM

Sort of on topic,.. I'm always looking for sources for electrical steel, and a while back I found some mega E-I pieces on Ebay. These things are huge! And you get 25 - 40 lbs of it for a decent price, considering you can't find this stuff anywhere in small amounts. The dude has several offerings to ...

Re: APL's V4 Cruiser Build.

Seat swing arm is done and drilled full of holes.. still needs to be made out of aluminum, but at least I have a good pattern to work with, and something to dial the system in with for now. I added some skirts on the bottom that hold the 12mm set screw 'stops', and help to stabilize the swing arm. S...

A little late, but I have to congratulate you on getting the newest version to spin! :thumb:
So nice to get some sweet success after all the work you've been doing, and all the problems involved!
I think your closing in fast on this guy,.. 3D printing the parts is a real game changer. :shock:

Re: APL's V4 Cruiser Build.

Thanks guys! :) Answering your question qwerkus, Ive been asking myself that throughout this build,.. so much of this could be Tig welded much easier! If it was a regular 'diamond' large-tube frame, brazing would be no big deal, but a small tube girder frame is best Tig welded I think, or at the lea...

Re: APL's V4 Cruiser Build.

Progress is slow,.. the swing arm, mount, & shock mount all have to get built together more or less, and clamped to the frame so I can sit on it and check the fit. Seat position.jpg At least I have that done, and the swing arm is on the way to being completed. Lots of steel to be trimmed off yet...

Re: APL's V4 Cruiser Build.

Well, I've changed my mind on the side plate a few more times, so who knows... now I'm thinking instead of trying to hide the box, maybe I should feature it with a little fear factor. :bolt: I have the rear mid tubes and bridges in, so the frame skeleton is complete, and now it's all about brackets ...

Finally have the front mid-tubes brazed in,.. after quite a bit of effort. Have to say though, it looks to be a massively strong front end.

Re: APL's V4 Cruiser Build.

Couldn't resist finishing out a ring joint, to see how it will look. Fillet brazing is a lot of work for sure, but it can look sweet! All that will come towards the end though, just before paint.
