Mechanics and Fixing Any Questions Answered

Impact driver.

What's the best way to get heavy oil and grease stains out of a workshop towel? I'd rather not put it in the wash and clog the machine up, but equally would rather avoid committing it to landfill.

Can they be soaked? I've got 3 or 4 microfiber towels that are soaked with grease/chain wax etc.

Probably easier to just leave that one in the workshop TBH.

(I would try soaking in a strong mix of clothes detergent, buuut might not work).

Rim brake

Left hand drill bit, slow speed and drill it out.

Left hand as sometimes the drill bit catches enough to turn the bolt free.

Then a 2mm easy out should finish the job.

would rather avoid committing it to landfill.

You have to wonder what's worse; burying it or getting more life out of it at the cost of spreading the goo on it all around the joint by cleaning it off.

Will a tiagra 4700 ten speed rear work with ultegra 6700 shifters ?

I’ve never thought twice about just tossing rags in the bin when they get oily/greasy/whatever but for me, getting used as a rag is end of the line, t shirts and boxers that I’ve worn out so instead of getting binned they become workshop rags. Use them for less grubby jobs first then the shit jobs as they get a bit grubbier.

Guess I’d feel different if I ever bought clothes specifically for rags.

Someone told me recently, charity shops often have a pile of T-shirts and that that get donated but aren’t in condition to sell that they’ll let you have for rags for free/small donation.

That ^^^
I’ve been known to actually buy them sometimes!

Nope, 4601 or 5701 would though.

Pure cotton or GTFO tho.

Towels are great. Best fabric is dish towel; rag nirvana.

Yeah, I hate all the crap that’ll come off a cheap terrycloth towel.

Get the Sora RD-R3000 GS derailleur, they'll work perfectly and enable you to run 11-34t.

Tiagra 4700 work with the 11 speed stuff.

Cool thanks will it work on a ten block though ?

Best rags I have found are pure white linen bedsheets!
Seriously, the dry cleaners near me also has contract for hotel laundry and linnen. When any bed sheets etc are damaged or unusable, they sell them for a pound. One king size doublet lasts about 5 years!

Since when has spell check become anti foreign words? Douvet is not exactly exotic and unusual.
C’est la vie.

It's not against foreign words, it's against your spelling of duvet🙂

Where I’m from we sez douvet! Says on my AliExpress packaging .
Lesson learnt. Will right it out 100 time after school.

Dishwasher tablet and a washing tablet, big old soak in a bucket, and pour it into the washing machine for a hot a wash as you can stand.

pure white linen

Like, cotton?

cotton?

Actual linen (made from flax) has some advantages over cotton

I know, just wondering whether @JohnnyOnions cloth is actually linen or cotton.

I have a 7410 hub that had a DA sprocket on it, using a Runwell 12-18l I cannot shift the bigger. Two local bike shops have had a go and both said “cannot, cut it off la”, and the third one that I called said that based on the first two failing they’d be happy to cut it off for me but they’d not bother trying to undo it.

Back in London I’d have clamped the sprocket in my vice and turned the wheel for leverage, but I don’t have a vice here.

What can I do that might shift the sprocket before digging the dremel out?

Chain whip which wraps all the way round the sprocket so it can't jump the teeth, wheel butted up to a wall with the tool pointed at the wall and pushing down. If you break the chain before loosening the sprocket, congratulate yourself and rebuild your chain whip with Wippermann 1R8 chain and try again. If you're not heavy enough, get a third party to whack the handle of the chain whip with your dead blow hammer while you hold everything in place, slugging wrench style.
