Latest Part Of David's (Mr Monark) Whizzer Special Build

[Goldenrod]

Although Joe Cargola was down with covid our second-rate (bench) team mastered a frame spreading challenge. Lacking a beefy frame spreader for this extra thick frame, they had to resort to the caveman technique of twisting ropes between posts. Just as both ropes broke, the five-inch brake and adjusters were slid into place without a single old guy bathroom break stalling the project. With all hands needed for success, the project lacked a cheerleading team and pom poms. The Illinois team had to settle for this gloating photo op. The young muscles of David (top right) and Tom Jr (right) came in handy. Al Toth, Bill Kavc and Tom Senior are smiling like baby racoons eating peanut brittle, but coordinating all the parts at once, was tedious. Now the build can continue.

The echo tube pipe experiment was also a success after a wider electrical conduit bender was located. At least two club members have had experience with adjusting an echo tube by gently bending the tube between two trees.

Proof pictured, that It takes a village to build a Whizzer!

Nice job!

If I'm reading this correctly it took five guys to spread the frame far enough to fit the rear wheel on, is that correct? Why not just spread the frame and do it correctly? You might not have all that help the next time you need to remove the wheel to fix a flat.

Remember, as the frame becomes wider, the fork ends are no longer parallel and in alignment and cause the axle to bow when the axle nuts are torqued. The frame width needs to be set to the same as the hub width, then the fork ends need to be re-aligned.

Maybe I'm not reading your post correctly?

This is the spreader that we invented and needed-- left and right threads. The end adjusters (not shown) adjust the axle but threading them through as the frame end wings while the frame is spread apart is difficult. A frame spreader will be made or found before a flat. We make and share our special tools. This was a emergency because only one exists and a death in our group caused a temporary loss of location.

How much for the lathe? I can do PayPal or cash on pickup. 😉

When you spread a frame with a tool like that (or even a port-a-power) you are assuming that the frame spreads equally, it doesn't. The weakest side bends first. It's just my guess that on a Whizzer modified frame it will bend out first at the left stays where they have been Whizzer flattened, and the brake clip was welded on. Checking, and setting frame alignment is a good thing to do during the mockup step, "before it's painted".

With the frame placed in a sturdy vise like in your photo, just use a thin string around the frame head, and attach it to the flat sides of your fork ends. Measure from the string to the seat tube on both sides. That will tell you which side needs to be bent out. As you already know because of the metal spring back you need to "over bend it" and let it spring back. A six foot long 2 by 4 works perfect if you do not have the Park Alignment tools.

After you get the exact width, you desire and have confirmed it is in alignment "front to back", then you need to align the fork ends which will be out of alignment. The fork end alignment has to be checked and/or corrected as the last step.

If you end up making a tool like in your photo, there's no need to make it with left and right threads.

Just make the left end "free spinning" on the threaded shaft, and the right end threaded. It works by spreading, and the pressure is divided equally between both hooks. The only advantage to a left/right thread is that it moves twice as fast.

I’d just like to say that we ended up spreading the frame only because we are using a 5” drum coaster brake which is noticeably wider than any other rear hub.
