Lately, I’ve been doing quite a bit of restoration-style work
, and it seems

especially
250\/400 and such
nostalgic old bikes
. And yet
most people’s bikes are so clean
I’m exhausted from masking<\/p>\n\n\n

\n

If I send it out for painting, things settle down for a while<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n


<\/p>\n\n\n\n\n\n\n\n

First masking, second masking
Safety first as we proceed<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Well then, I removed the front and rear calipers.

This era’s characteristic
bottom case with threads cut into it
*The rear is normal<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I struggled hard for the first time in a while
They wouldn’t come out at all (\uff1b\u2200\uff1b)

No way, full power
I finally got them off with air pressure<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The seal hardness isn’t quite “the worst ever”
but I wouldn’t say that

there’s no flexibility at all
It moved so well…
I was amazed<\/p>\n\n\n\n

\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

Not just the seal groove
but also between the oil seal and dust seal
there’s corrosion
basically it’s stiff even without seals<\/p>\n\n\n\n

\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

When it comes to rotary tools… Nakanishi
Emax EVOlution<\/a>
It’s fairly pricey…
It’s for people who want to stay in the industry long-term and seriously.

The abundance of tip tools
and the convenience of tip replacement are very capable<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If I wet it suddenly, it gets dirty
so I do a rough cleaning with a stainless brush<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The thin rotary tool is really excellent.

What’s great about this Nakanishi is
you can switch between high-speed and torque types
*You need to buy the motor (handpiece)

Well, I don’t have the torque type…
but the work is still fast
everything needs the right tools<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

I gave it a good wet blasting
and sure enough
wet blasting is amazing
honestly, it’s an essential tool
without wet blasting
“it takes time and the finish is poor”

If you’re wondering what to do
definitely consider getting one this year<\/p>\n\n\n\n

<\/p>\n\n\n

\n

It becomes matte-finished so it’s less prone to corrosion.<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n

\"\"<\/figure>\n\n\n\n

I completely dried any excess moisture in the oven
cooled it down, packaged it, and shipped it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Once I finish shipping in the evening
I’ll sort through the remaining removed parts<\/p>\n\n\n\n

\n
\n

Oh, it’s clean<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\n

The piston doesn’t have much rust, but<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

there are some burrs
so I’ll consider price and balance<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The rear pads also show uneven wear and are at their limit
so I’ll replace them<\/p>\n\n\n\n

I see…
25\u03c6 is pretty niche…<\/p>\n\n\n

\n

Since it’s been sent out for painting
I’ll put it on hold for now<\/p>\n<\/span><\/span><\/span><\/div><\/div><\/div><\/div>\n\n\t\t
