Back rubber side down (for now)

After finally getting the suspension bushes sorted I got them refitted and I think they look pretty good (ok this photo only shows one fitted but you'll have to trust that I fitted both, or scroll down)



Before I could get the wheel back in, I needed to refit the mudguard but before I could do that I needed to address the cracks in the guard at one of the rack mounting points. I didn't want to mess with the paint, so I decided to drill the ends of the cracks with a 1.5mm drill to stop them spreading and then a template was made for a piece of stainless.

Rear suspension top out bushes

As I have mentioned before, the rear suspension top out bushes have been causing quite a lot of pain. Obviously there are no spares available for this bike and sourcing something appropriate was proving quite difficult. The bushes are made of rubber and are 50mm OD, 32mm ID and 25mm tall (some of you may recognise those numbers as metric conversions of 2", 1 1/4" and 1"). I managed to find some large bushes that are 50mm OD, 23mm ID and 50mm tall. Plenty of material for me to make mistakes and I also had to order 5 so I've got plenty to make replacements in the future. 




Here's one compared to the better of the originals

Rear mudguard repair

The back section of the rear mudguard hinges open to allow you to remove the rear wheel, well that's what's meant to happen but the hinge was basically non existent when I got the bike. The rear section is a different colour so I'd always thought it wasn't original to the bike (although I had assumed it was the correct one) but on closer inspection the profile is completely different (look at the beading in these two pictures - top one is the main guard, bottom one is the removable section) and the 'new' bit is also a lot rustier on the inside. I don't think I'll find the correct one that easily so I'll work with what I've got.

It's been a while.....

Sorry it's been so long since the last post but for a while I wasn't making any progress so had nothing to write about but that's all changed now! The last post was about stripping the rear suspension down to sort the perished rubbers, they've been a real headache as spares for this bike are non existent. After a lot of searching and headscratching I came up with a few possible solutions such as casting new ones, making them up out of sheets stacked on top of each other (worried they'd separate and get mangled) and I even had an offer of 3D printing them but that came to nothing. In the end I've found some bushes that are the correct outside diameter and the inner diameter is too small so I'm going to have to enlarge the bore, probably using a grinding wheel mounted in a dremel mounted on the toolpost of the lathe. They're also too long but that should be easy to sort with a large knife. They have just been ordered so the project can start moving forward again.

I have made some progress with a few other bits whilst I've been thinking about this though.

Rear suspension strip

The bike has a new home and is now sat on a wheelable platform with the frame supported by a rotary table delivery crate. This means I can take both wheels out at the same time without the bike falling over and I can work on all sides really easily by pushing the platform around. I'll take a pic that shows the set up properly for the next instalment


With the rear wheel out I decided to have a look at the rear suspension to work out what parts I needed to track down. With the upper and lower pinch bolts removed, I had to work out how to remove the large tube that the suspension runs on. I re-purposed some Hope Technology bicycle hub bearing press tools, a piece of aluminium tube and a big length of threaded bar to create a press. I wound the tension up then used an aluminium drift on the top to push it through. I repeated this process until the tube was all the way out.

A note on supporting local skills

I've just realised that in my last post I did what many of us are guilty of, I didn't give credit where it was due. I may have gone to the effort of finding someone local who came highly recommended to polish and plate the links but I then didn't do my part as a customer, and local person, of telling anyone who it was. This has probably got something to do with me not going to university so I've never needed to properly reference my sources but I'm going to put that right now.

Before I get to who the plater was, I've mentioned above that they came highly recommended; by who? There were actually quite a few places but the main one was the ever useful Sheffield Forum (here is the exact thread if you care that much). I used it as a starting point and tried a few firms. Most of them had a minimum charge of £80-100 and even admitted that my parts weren't that much works, and NONE of them were even slightly open to my requirements regarding a 'non perfect' finish.

So I worked my way down the list and got to Martin who works with Anchor, based at the historic Portland Works (first site to produce stainless steel) in Sheffield city centre. I did some Googling and found quite a few glowing mentions of his work on various biker forums (I'm not referencing all of them) so I got in touch. When I dropped the parts off he understood that I didn't want them to stand out on the finished bike so suggested not doing a full polish and we decided on nickel instead of chrome, despite other parts on the bike being chromed.

For reference, here are the links before I did anything to them






The only issue I had was the timescale and I think I am partially to blame. I said I wasn't in a rush so the parts ended up taking longer than I expected. Maybe I should have said I needed them ASAP even though I didn't. Even though I was getting a little frustrated at the delay, once the parts were back (and Martin was VERY good at meeting me as I couldn't get to his workshop whilst he was there, above and beyond the call of duty there) I completely forgot as they were exactly what I'd hoped for


How much would you expect that to have cost, bearing in mind the minimum charges mentioned above? £60? £50? Maybe a bargain at £40? I paid just £20 for these parts to be cleaned, old plating stripped, brushed/polished and replated. I knew they weren't going to be expensive but this is frankly ridiculous.

Why bother writing all this I hear you say, well the whole process has made me realise that we need to support our local businesses that do the things we can't do ourselves. Skills like these are not learnt over night and if we don't use them we will end up in a dire situation where we cannot, for example, get parts replated for a reasonable cost. We will then be left with a difficult decision of paying over the odds for services or buying new parts of questionable quality (not an option with an Automoto)

I will be making an effort to hunt out a skilled craftsperson next time I need something I don't have the skills or equipment for and I will pay their price without arguing or haggling. Rest assured, Martin will be my go to guy for plating in the future and I will probably overpay him next time as I don't think he charges enough. This doesn't just apply to motorbike restoration, I'm talking about local cafes, carpenters, plumbers, mechanics, veg shops, bakes, butchers, speciality shops and anyone else you can think of that does something that you can't

To sum up, use your local talent and tell everyone you know to do the same

Factory Floor: an Archive Sheffield Film from Nathan Gibson on Vimeo.

During 2013 photographer Clive Egginton began his residency at TSL Turtons, a spring making factory in Sheffield. As "Archivist in Residence" he worked alongside the men in the factory, documenting their day to day life and working methods.

Clive visited regularly over a period of several months, building up an extensive archive of documentary images and large format portraits. As the project progressed it became apparent that the factory would also provide a compelling subject for a short documentary film and to this end Clive invited his friends Nathan Gibson and Marcus Sarko to collaborate. Filming throughout the winter of 2013 and into the new year the three gradually brought together the 15 minute portrait "Factory Floor", presented online for the first time here.

Sadly Clive fell ill with cancer during the final stages of filming and as a result suffered significant damage to his vision. He passed away peacefully at the end of September 2014, only days after an exhibition of tactile images made for visually impaired people - the first of it's kind - was held by close friends and family with assistance from the Royal National Institute of Blind People.

Forks that go boing in the night

I finally got the fork links back from the plater and I'm more than happy with the result and it's official; nickel kicks chrome's arse any day of the week. If I ever get a classic car I'm redoing all the chrome in nickel. The picture doesn't do it justice but it really is lovely. The slight scratches are intentional, the links were brushed rather than polished before the plating so they didn't stand out, I think it's worked really well. If I end up decided they need to be a bit more abused I'll take an abrasive pad to them to knock back the shine of the nickel a bit.



I've been quite busy but on Wednesday I had a couple of hours so decided to put the forks back together. It's easy to see why forks like this don't get used any more, this is quite a lot of parts for a fork that isn't particularly good.



Among those bits are the new friction washers, they're actually for a Motoconfort but they are the right size



I got them mostly back together then tried to put the steering damper in and realised it wouldn't fit past the mudguard and the lower pivot axle held it in place so some of it had to come apart and be re-assembled once the damper was in. The headset and pivots need properly adjusting but this will be a lot easier when the bike is sat on a pair of tyres that hold air and I've got a functioning front brake. The brake isn't working as I've taken the shoes out to be relined, I'll do the same with the rear next time I take the wheel out.




Now the bike is now sat back on it's wheels ready to be moved out of my brother's garage as he needs the space for his project car. Once the bike is in it's new home I'll be trying to get it running (now I can plumb the fuel 'system' in) and then addressing the small welding jobs (foot peg and rear mudguard) as the new home is a fully functioning bicycle frame building workshop so I'll have all my tools to hand including TIG, oxy-acetylene, pillar drill, lathe, mill as well as every hand tool I could ever need
