Disk brake conversion on a bicycle

Front disk brake conversion

This morning in the workshop,  I decided to convert my bike from rim v-brakes to disk brakes, I wanted to practice because I’d to convert a few retro bikes later this year.

Anyway, here’s how I did it…

Front disk brake conversion prerequisites

A breakdown of the things I used to compete the conversion:

Disk Brake Adaptor

You can create your own from steel or source from eBay, I ordered 5 from eBay but I modified them.

Disk brake hub (or wheel)

It was more time and cost effective for my local bike shop to provide me with a rim and hub and brake disk.  I got a good deal on a Shimano centre lock system and rim.

Disk brake calliper

Pick any of your choosing but I selected one with the most standard mounting system I could find only to make the installation as simple as possible.

Welder and Angle grinder

Welder is needed to attach your adaptor to the frame and the angle grinder is needed to make cuts to the adaptor and grind away and finish the surface from imperfections after welding.

So, how I converted to disk brakes

For this, I needed Welding equipment, angle grinder (cutting and surfacing) and allan/hex keys.

The first thing I did was to install the wheel onto the frame.

I remove the mud guard arm and spent some time how my disk brake adaptor could fit.  I am sure there are some good engineering techniques that could have been used here but I simply took the brake calliper, attached the brake mounting adaptor and slid it onto the brake disk.

I then fiddled around until I could get a good fit without disturbing the motion of the wheel.  Once I found a good position, I checked to see that the brake pads made good contact with the disk surface.  Not forgetting that the pads would have good surface coverage when clamping the disk.

I had to make several adjustments to my disk brake mounting adaptor and decided to use cardboard to get the exact shape and size that I would be the best fit.

Welding

Now, I prepared the fork for welding, I removed the paint on the fork and adaptor with a wire wool brush on a drill.  Hooked up the Welding machine with 0.8mm wire.  Safety gloves on, mask and clothing on.

Welding was a little tricky, but I was able to hold the adaptor with one hand in the position, test the wheel motion – the wheel has to be moving  without grinding or friction or at least you should be confident that you have enough play for adjustment after you have finished welding.  The brake calliper had bolts with washers that would allow for angle adjustment.

I welded both sides of the fork and ensured the joints were strong enough.  My welding skills are still relatively novice but I got a solid weld in the end.

Angle grind to remove excess weld spots and use a sanding disk to smooth the steel surface ready for paint.

Once the welding was finished and grinding completed, I gave some final testing and adjustment.  Everything was good and started tightening things up to be sure no further adjustments were needed before road testing.

Once I was satisfied with the fit,  I added some primer ready for some new paint… but that’s another day 🙂

Does Google index links inside a NOSCRIPT tag?

There is no doubt that the NOSCRIPT tag is a very tempting but useful tag for Lazy loading techniques, image loading, pagination and Javascript fail-safes but if you’re like me who has been scratching their head wondering if it has any influence over how links and content might be indexed and crawled by Google then please make your thoughts heard!

I’d certainly like to know the answer to this one!  Are they Indexed, Crawled, Followed, Page Rank distributed, etc

So, I’ve been testing on my own website and gave the following scenarios:

TEST 1 – Page with Just simply a NOSCRIPT block with a sentence and hyperlink in it.

TEST 2 – Same as Test 1 but as well as the sentence with a hyperlink being inside the NOSCRIPT tag, it is outside of the NOSCRIPT tag

TEST 3 – NOSCRIPT tag with a sentence and hyperlink Link contained.  There is also a piece of javascript that generates a Link and places it outside of the NOSCRIPT

Why?

The idea of my tests was to see if Google would show any unwillingness to crawl any of the hyperlinks and prove a point that links inside a NOSCRIPT tag are not indexed.

Result

Googlebot crawled and indexed all links…

Conclusion

Google must give some consideration to links inside a NOSCRIPT tag, I’d be curious to know what the conditions are despite their recommendations on the Web Master Blog. Maybe my tests are flawed or I’ve messed them up ?

Why is this important to know?

Firstly, it’s bugging me to know and I’m sure many other SEO’s what to recommend to developers when they ask (well some Developers!!) about these issues.  If I was to tell a developer that they could NOT use a NOSCRIPT tag, then they would have to spend time developing a complex work around solution I’m sure, before I do that, I want to be damn sure.

So does this mean Page Rank is passed or distributed with a NOSCRIPT tag?

On this round of tests, I have not tested this but this is still open to debate, I’d certainly be interested to know the answer to this question since this means that a majority of e-commerce engines use front-end code using pagination and lazy loading based on NOSCRIPT tags.

If Google is unable to process the Javascript or it’s blocked then and Googlebot relies on the NOSCRIPT implementation to crawl content.  In this case, I’d then request that developers implement solutions that allow Page Rank to flow from product categories to products themselves and it is down to debate whether a NOSCRIPT tag allows this.

I’m certainly open to discussion guys, welcome! 🙂

How to get a free bicycle in Helsinki

Yes, it’s possible to get a free bike in Finland, you just need to keep your eyes and ears open…

For example, check out my free bike… it’s my battle cruiser, ain’t she a beauty??

Well, I found this bike out of a container in Kallio.  It didn’t cost me a penny and I didn’t do anything illegal to acquire this bike.  Admittedly, it’s a lady’s bicycle but it’s hipster to ride any old bike around town – so who cares! It works fine and I made some improvements to it out of my own choice and it’s good as new.

Anyway,   start your find for a free bicycle in Helsinki by logging onto Facebook and joining the Container group.  Occassionally there are organised cleaning periods made by housing companies to remove unwanted and old bikes.  They appear on this page occasionally and if you are sharp you’ll be able to get along to a container and choose a bike for free!

Good Luck!!

Trying Mämmi for the first time

So I’ve been bracing for this moment, trying Mämmi for the first time, my girlfriend tells me it will change my life.

I’m bracing for the moment, it has just been handed to me and it’s staring at me, so here goes….

Mämmi with Cream.  Finnish tradition!
A bowl of Mämmi with some Ice cream. A Finnish tradition.

So…. my verdict, it’s very good!!! Try yourself. Good Finnish tradition, warm Mämmi on cold ice cream.  Looks like somebody did something brown and nasty to your desert, but don’t think of it like that- honestly!
