Of Sand, Wood and Crossing State Lines: The Quest for a Curvy Fork

Because I like to keep things simple, the bicycle I am making is of course a low trail design. And low trail means a fork with a lot of rake. A very curvy fork, in other words. Not only did I want it to be curvy, but I wanted it to be that special kind of French-curvy where instead of a gradual "banana" bend, there is a dramatic flick toward the tips of the blades (like so).






When you buy supplies for making a fork, what you get is two straight blades that are (hopefully) a bit longer than you need them to be, and a crown which those blades plug into. It is then up to you to rake the blades. The style of bend I wanted requires using blades that are designed to withstand such dramatic manipulation. I went with the Kaisei Toei blades, which were already familiar from other projects I've been involved in.






To get the fork blades bent as desired, we needed a special setup that was not locally available. So we payed a visit to Cirlce A Cycles in Providence RI, about 30 miles from Mike Flanigan's shop. They have a fork bender that was made specifically for the French-style bend and could produce the 73mm of rake I wanted. The furry receptionist granted us permission to use it.






Since 73mm is a pretty dramatic amount of rake, Chris Bull suggested filling the fork blades with sand before bending. This would reduce the possibility of damage during the process.






The blades were taped at both ends to contain the sand.






The fork bending press consists of a wooden block curved according to the French bend design (they have several of these presses, used for different styles of bends). There is a notch along the curve where the fork blade sits, held in place by a vise.






A giant lever is then pushed up, forcing the blade to adhere to the curvature of the wooden block.






The further up you push, the more dramatic the bend.






At first we did not have an idea of exactly when to stop, so Chris eyeballed it and stopped when he thought the rake was around 50mm. Confirming that this was correct and that the bend was forming properly, he then continued the process until we finally had the 73mm rake we wanted.






This is the dropout placement mockup. To determine the rake correctly, you need to know how and where the blade will be connected to the dropout.






One thing that can go wrong during this process, is that the steel can get distorted. When this happens, you can see and feel a rippling on the inside of the bend. Thankfully this did not happen.






For the second blade we now knew exactly when to stop and had a marker in place. I did part of this bend myself and it was pretty cool to feel the blade give under the force of the lever. It is interesting that Circle A's setup makes you push the lever up rather than pull it down; I have never operated this kind of press before.






Thanks to Circle A, I now have two symmetrical, beautifully raked fork blades that are waiting to become a fork. All I have to do is braze it.

House on Fire

After our "rest" day with minimal hiking and another soak in a hot tub last night, we were ready for another full day of hiking adventures. Our first hike of the day brought us to Mule Canyon on Cedar Mesa, to an ancient Anasazi ruin known as the "House on Fire". Since we were now at a higher elevation than we had previously been on the trip, the environment was a bit different from what we had seen so far. Mule Canyon was a beautiful hike with a LOT of trees and shrubs and even a little bit of water in the canyon. It was a shock to do a hike with so much vegetation, because most of the hikes we had done so far were in open desert andextremely dry with very little vegetation.





















































The hike to the House on Fire ruins was a very pleasant one with minimal elevation change. After about a 1.5 mile walk we rounded a bend in the canyon and immediately noticed the ruins on the right. House on Fire is just one of several ruins in Mule Canyon, and was occupied by the Anasazi. According to literature that we saw about the area, the ruins in Mule Canyon are over 800 years old and have never been excavated or restored in any way. The House on Fire ruin is so named because of the overhanging cliff above the ruins that has patterns in it resembling flames. If you visit the ruins in the morning all of the light illuminating the House on Fire is reflected light from the opposite side of the canyon, which means that the roof above the ruins glows with warm light and contributes to the "fire" look. We found it a fascinating site to visit. We would have loved to hike through more of the canyon to see some of the other ruins but we had a long hike planned within Natural Bridges National Monument so after taking in the wonder that is the House on Fire, we hiked back to the truck and continued on to Natural Bridges.

The Copper Falls Trail

Monday, August 8th - - For some reason, I was quite ambitious today and went on a second hike. This was a 1.7 mile loop through the forest, along the river, with a few stair-steps involved as well as some other downhill/uphill sections where there were some handrails to help provide support. I'm not ashamed to admit that I made ample use of the handrails!



The trail would also cross two rivers in three places on very sturdy foot bridges and we'd see several waterfalls along the way. The pictures I took really do not do it justice. To fully appreciate the area you have to be there – feel the spray from the water and hear the roar of the river as it drops over the ledges and through the narrow passageways that it has carved out over many years. This was one hike that was definitely worth the effort!





A small portion of Copper Falls, which drops about 12 feet, on the Mad River. Like the Tahquamenon Falls, the copper color comes from tannin in the water.





A slightly better angle, but still showing only a small part of the falls.



This view shows it a little better – how the river has carved two paths around and through the stone walls of the canyon - but I think the only way you could get a really good shot of this falls would be by being suspended over the river in front of the falls, with a wide angle lens on the camera!



Flowing in a northeasterly direction, the Mad River essentially “runs into” a stone wall, making an abrupt left turn to the west. Coming in from the east is Tyler Forks. Visualize a rather crooked “T” with Mad River being the long upright part as well as the left hand part. Tyler Forks would be the right hand side of the “T” with a bit of a zig and zag just before and after it meets up with the Mad River.





Brownstone Falls is created when Tyler Forks plunges down 30 feet to join the Mad River. The name Brownstone comes from the color of the rocks surrounding it. They were formed eons ago from lava flows that contained small quantities of iron. Tyler Forks curves off to the right, eastward, above Brownstone Falls.





This picture provides no perspective whatsoever! But, there is the Mad River coming in at the top of the picture. The “whitewater” at the bottom of the image is actually Brownstone Falls dropping over the edge of a 30 foot cliff, plunging down and meeting up with the Mad River. Together they continue their journey as Mad River, veering off to the right (where the white foam is in the center of the photo). The sound was incredible. Not nearly as loud as Niagara Falls by any means or even Upper Tahquamenon Falls, but the sound reverberated around the canyon.





Okay, maybe this is a little better. But it still appears as though the water is flowing in from the right and the bottom and going out the top. You'll have to trust me, it isn't.





Adding to the sound of falling water was Tyler Cascades, which is a set of four smaller waterfalls just above and to the east of Brownstone Falls. Simply Gorgeous!



The trail followed Tyler Forks to the east a little ways then crossed at a point just above the cascades. By then the roar of Brownstone Falls was muted and the sound of the water tumbling over the rocks was quite soothing.



Oh, yes! This was one hike that was definitely worth the effort! And I savored every minute of it...

Snowpack Profile Update. Waffles!

Wow, big news here at the Old Station in Paradise. We now have a computerized weather display running 24hrs and Waffle Weekdays will be starting this week!

The computerized weather display is located inside the Old Station in the windows to the left of the inner door.

You read that right. If you can't get enough of the Mountain during the weekend and can make it up on Friday you can join the ranger(s) in the Old Station for hot drinks and waffles. Start your weekend early between 11 and 3 this Friday, February 10.

Please bring your own cup or mug, donations of hot drinks, waffle makings and fixings will be gratefully accepted (new and unopened) to keep Waffle Weekdays happening.

Now for why you really read this, the snow pack profile update. No failures were observed in either the compression test or extended column test. All layers were fairly dense and well settled.

Stellar weather and long term forecasts

I found this long term forecast from the Climate Impacts Group. They've done a little weather projecting into the fall and winter (and even the spring). Here is an excerpt,

The seasonal outlooks through spring 2007 suggest... a continuation of warmer than average conditions throughout the region for the coming fall, winter, and spring seasons... pointing toward[s] a weak-to-moderate intensity El Niño event for the next few seasons... suggest[ing]... an anomalously dry fall and winter for much of the region.

Of course there were some serious disclaimers, but if you follow this prediction, the forecast doesn't look so hot for skiers.

In the meantime, it's warm and dry on the mountain. Camp Muir enjoyed a balmy low of 49 last night! It's at 59 degrees as of 9 AM.

Southwick and surrounding woods

About 6 miles. 2 hrs 15 mins. A couple of showers but nothing really wet. As I got home the sun came out.





Lovely walk, with only likelihood of wandering off track right in the last half-mile or so.

Quite up and down. I parked by Southwick church and walked up to the water tower on the Glapthorn Road, but there's a fair sized lay-by at the top. Of course that puts the uphill road walk at the end.





The track starts about 100 yards past the water tower, to the right.

It runs through at least three fields of this crop - is it bamboo? Pandas next?





(I'm told this is a bio-fuel crop)





It was very windy up on the ridge, but the plants were some protection as they were taller than I am.





The hedges around had lots of blackberries.





For much of the way the path runs beside Short Wood Nature Reserve.









After about a mile or so the track comes to a metal gate leading into a large meadow, and today I was treated to the sight of these two little deer.





I was surprised when they came towards me at first, so I tried to get a shot - usual problem of the wrong lens for the job, and the splodges are raindrops! It was a joy to watch them leaping about. The wood behind the deer is part of Glapthorn Cow Pastures Nature Reserve, famous for nightingales in May, and black hairstreak butterflies in June.The cows were in the lower part of the field keeping themselves to themselves.





The track goes across to another gate, then right on a road leading to Provost Lodge. I followed the path between the two big barns and through a gate then downhill. According to my instructions it crosses a stream, but it looked as though there has been no water in the stream bed for some time. The path goes uphill to another gate, past a gap in the hedge. At the gate I went slightly diagonally left towards yet another gate. Then turn left towards an old farm building - this part of the walk is alongside a ploughed field. There is a bit of grass along the edge, but it's a bit rough in places.

At the old building (Tottenhoe Lodge) turn right and carry on going north, with a hedge on your right until you reach a wooden footbridge almost on the road.





There's a bridge which you have to cross - it brings back memories of cycling over to Suffolk almost twenty years ago, as I remember stopping here for a rest, and Harry drawing Crossway Hand Farm on the hill.





I followed the concrete track towards the farm, turning left just before it, and then along the track towards Boars Head Farm. There is woodland immediately on the right, but no public access as it's a conservation area. The track continues as a grassy path just past Boars Head Farm, going downhill and entering the wood, at its narrowest point. There is a clear path to left and right. We go to the right along a gravel track signed with a horseshoe. As I walked along here, I first heard, then saw a couple of jays - are they burying acorns already?

I followed the route straight through, past three paths to the right. The last one of these leads to Shire Hill Lodge, but the path becomes very narrow for a short distance before joining the track .

Soon there is a small plantation of fir trees on the left, and at the end a footpath cuts across the track. I turned right - it's clearly marked as a footpath, but not for horses. The path turns left after another young pine wood. When it joins a gravel track go straight on, not to the right. A little later turn right and follow this path directly to Southwick.





(If you come out of the wood and spot the Water Tower on your right, a little behind you . . . retrace your steps. If you're out of the wood you should have the trees on your right not your left!)

Spot the statue?

You arrive at the church after crossing a footbridge over a stream and following a small lane to the footpath signs and two benches.

No, it's not the leaning tower of Southwick.
