making steering shell with metal lathe

I made steering shell with metal lathe. At least 6 fuses were broken.

 Because I haven't had experience to make steering shell. it's different with reamers for woodwind. The diameter of rod is 36 mm. The finished diameter is 35 mm.

 The limit of diameter of boring with this lathe (7x14) is 16 mm. If more bigger diameter is needed, I have to use boring tool.

 Speedy rolling and slowly inserting drill bit.

 Then I used boring tool to make the diameter 28 mm and the depth is 8 mm for bearing.

 Done. I may be make this part from pipes. But Bearing is made based on the meter. the pipe is made based on the inch. That's problem, I think. The lathe needs taking a rest a once a 30 minutes. I can do the other job.

 Cutting iron plates to be square. Each thickness is different.

 at first, rough cutting, then finished.

I'm too perfectionist ? I don't think so.

Fini.

start making new bike

I cut some wood parts as spacers for welding.

132 mm is for front wheel, 192mm for rear. that's opposite of normal bike. I think that the parts of fork also needs spacer. so I made 3 spacer.

Then I cut iron material.
one is for a shell of steering. the other iron plates are for suppoting the pivot.

today's working time was less of an hour.
I need better pen or something to mark.
Fini.

attaching sprocket

I recieved a tool to remove the sprocket. it can be used to attach sprocket to free hub.
At first, put grease on free hub.

Then attach sprocket.

The left gears also attached to free hub, then turn the lock nut to right.

At last, I used the tool to attach and remove sprocket. 40 newton is needed to lock enough.
Fini.

start preparing my python 2nd and 3rd

I have already started preparing next mission.
it's making some more pythons.
What's python lowracer ? you can know by clicking the link.
It's recumbent FWD.

 I bought some secondhand wheels and some new tires and tubes. This time, I'm going to make smaller pythons which tire measurement is 20 inches.
First Step, I checked wheel's condition, I'm sorry I forgot the photo.
Then attach tire to rim. At first a side of tire is attached.

 Then inflare tube a little and put it in rim and tube.

 The tube needed a little more air. push it in and push it in.

Check the condition of tire and tube and rim. then inflaire tire !

 Complete ! I did more 2 tires.

 The last one's wheel is for BMX. So the number of spoke is many. the axle is needed to change. it's a little bended. I need more one tire. I'm going to make it by my self.

Fini.

Latest riding

I got better steering technique. now I can turn without supporting bike with arms.

 I went to neighbor city by bike.

Change to LED light

I changed front light to LED one with Dynamo for LED.

It is lighter pedaling than normal one.

Side view.

This is the dynamo. when it is attached to the python lowracer, Ordinally Top is under side.

I need rear light, too. I attached it to the back of my helmet.

It's very shiny. we should not see it directly.
side view.

Hummm. with more ornamentation isn't bad, I think. Although I don't have any idea now.
You know we have a program of TV for kids which series is masked rider.
I want to get such full masked helmet. Because I have asperger's syndrome. With the helmet with mirror coating glass, the stress to mental decreases.

At first, in the world, it's important to find by what decreases the stress. I think so.

Front derailleur

At last I got bottom bracket for sports bike.
then I could attach front derailleur.

 Bigger chain wheels has 52T. Smaller one has 39T. The one with 42T touches the frame, so it was changed to 39T's.

 I changed the chain new one. I bought 2nd hand chain wheels. I had to bend then to adjust.

 The spring of the front derailleur is too hard.

Attaching a part of the seat

This is a mat for bath.

Just cutting to fit to the measurements between 2 parts made from board.
Then maked holes to tie up.

Just it is tied up with nylon strap.

View from back side. The flexibility of the mat for bath looks better.

When I sit, it fits to my back better. it works to support my shorter legs.

The mat for bath is cheap, but good material for a part of seat, I think.

By attaching the mat, the seat can not be fold.
That's not bad. I will ride more comfortable.

Before that, I got max speed 44 km/h.

Since getting it, I have not gotten more speed.

Max speed 42 km/h

For these days, I can get max speed 42 km/h with front chain wheel 42T and rear 11T.

I have riden for about 1900 km since this May.

When I rode about 1780 km, The screws of pedal attaching wider plates were broken. Now I use normal pedals. Off course My legs keep the length.
I use the near part of toe for pedaling like road racer.

Changed Free Boss type sprocket

I used Shimano 7s MF-TZ21 ( 14-16-18-20-22-24-28T ) for rear free boss type sproket.
For front chain wheel, I use no maker logo 42-52T, But Front derailleur can't attached, because the BB's shaft is too longer. it is for belt drive.

My top speed is 32 km/h with front 42T x rear 14T. Now I can ride more stably.
So I want to try riding more speedy.

Then, I bought New Boss free sprocket made by DnP in Taiwan.
LY-1107HFN ( 11-13-15-18-21-24-32T ).

I rode with this sprocket in this early morning. I can get the speed 35.5 km/h with front 42T x rear 11T.
Off course, Safety driving is the first one.
Fine.

Repairing Back Fender

My back Fender was broken twice.
In the both case, the fenders were split.
The following photos are my second case.

 This Fender is for front wheel. The first back fender was split then I repaired it left 2 front fender. But it was split again.

 What's the problem ?
I bought new fender set made by Taiwan. Taiwan's is almost same level of Japan's. They are more better than China's. But China's is cheaper. That's also nice.

The V stay is rare, I think. I have never sawn it.

 Back Fender was repaired. It's easy task.

 This is the function of pop off. When big attack happen from ground, The parts will separate not to split the fender.

 I like The V stay. A pair of bolt and nut attached it.

The top of fender attached Bolt and 2 nuts and rubber sponge.
In this early morning, I observed it with riding the bike.
I think the pop off works too much. I stopped my bike for some times, and I connect the separated parts of pop off.

cleaning the chain

This chain is made about 30 years ago.
When I made my python, I bought 2 donor bikes which were made in about 1980.
Before making my python, I cleaned it. Now almost 2 months have passed.

 The chain's color is black. originally it's silver. very dirty.

I cleaned it with the gasoline. we can see some silver parts.
Off course I cleaned chain wheel and rear sprocket.
Finally I attached the chain to bike and gave the lub.
Is the cleaning  needed once a month ?
If non oil chain is used, we don't have to any lub for it ?

Riding more distance.

I went to nearer bigger shrine with my python.
it' is in the mountain. I enjoyed riding down and up hill. Almostly up.
I saw the god wood there.

I think the wood is younger.

Tunnel of trees.

I tried taking my shadow a movie

To keep distance is hard.

train and train with enjoying !

34th practice to ride python

I had practice to steer. riding on circle, turn like the letter of S, turn like the number of 8.

I fell down once by slipping. falling down means tring the limit or something new.
So not bad thing.
FIne.

32th practice to ride python

I tried riding python with slow speed.
It isn't easy to get good balance. it's good exercise, I think.

Fine

33th practice to ride python

I tried riding on the line of 8.

I can turn with pedaling ! that's more stable.
I fell down for 3 times today. I rode for about 50 km yesterday. I have been tired, Maybe. In the other hand, I can ride such long distance.
Fine.

Adjusting the steering BBS

When I sit the seat, I felt a bit step.
Adjusting BBS to steer, or something, I thought.
At first, I screwed off the seat and My python was made lay down.

 Then the fix nuts were screwed off and pull off the both steering cranks It's better to take off the stand.

Then the bolts and nuts under the middle part were screwed off and took off the under crank.Then the middle and rear parts are took off. the angle to take off them from front part is important.
I checked the rotating of the BBS, but I couldn't find any bigger problem. Maybe the screws and nuts got loose, I guessed.

If steering is more heavy, we can get more stability to steer ? This time, I adjusted it more tightly.

Then re-builted. some painted parts lost paint. I painted a few parts. I want to try to ride. But for some days rainy weather will continue.
Boring...
