I have a 1981 Koga Miyata Full Pro that I'm upgrading. I bought the frame and fork off ebay for £101.00

I had a 1983 Koga Miyata Gran Winner with the Golden Arrow groupset and transfered the components to the new frame. I sold the Gran Winner frame for £80 and will upgrade the groupset on the Full Pro to Dura Ace 7800 (10 speed), but with the Dura Ace 7900 compact crankset (50/34T)...

the 7800 rear deraillier is good for a cassette with the max of 27 teeth (according to the Shimano Specs), but many say that an 11-28 will work fine ... This will allow me to use the wheels on my Giant Tcr from time to time (Hed Belgium Plus rims with Chris King R45 hubs (ceramic bearings)... these wheels have a 10 speed cassette so there will be no faffing with changing the cassette everytime I want to use them on the Koga

the frame will be sent to Bob Jackson for a respray (original French Blue colour), with new decals fitted

a set of decent light tubeless ready wheels/tyres, some Apidura bags and I will use this bike for some Audax rides. I doubt that I will be able to fit mudguards though as thereis very little clearance by the brakes

I'm hoping to have the finished build weighing approx 8kg. It's a suberb bike and definately a keeper

I had the Peugeot out for a test ride yesterday afternoon (as much to see if my knee was going to co-operate for a club do next saturday as to test the bike).
First thing, the front low-loaders do foul the drum brake torque arm enough to drop the front wheel by half a brake-block. The brakes are on the limit so the carriers had to come off. Mod planned to drill a couple of new holes toraise them as necessary.
On the ride it was soon very apparent that the hand strength of Goliath would be necessary to make the coupled brakes work properly in an emergency. The front drum brake slows a solo up more than it does a tandem but is a speed control rather than a stopping device. The solution (being done now) is to separate the calipers into a conventional arrangement and put the lever for the drum elsewhere (my choice is a mtb thumb shifter on the vertical part of the quill stem).
Other than that the ride was a success, very pleasant. A lot of fairly rough roads; not very quick but very comfortable.

How bad is the ground clearance with the standard cranks and 406 rims? I checked on the weekend and it will fit in the car assuming I can remove the stem (need to undo the brake bolt and remove that cable). I've found the BMX forks with V bosses, and I've got some 406 rims kicking around, (or I could just buy some new ones), but that way a proper project lies - if it's going to mess up the crank clearance I'll stick to 451s and have to do something different with the headset.
Good enough - just over 10 inches, about he same as many road racing (but not criterium) bikes.
Never tell me the odds.

Singular Peregrine returned from the bike shop having had headset cups fitted.  I put together the rest of the headset, then plonked it on the wheels, and put the cockpit assembly on.  Also the seatpost in, but it's a bit tight now, so I shall need a bit of patience.

I forgot to bring the copper grease from Worthing, for which I am kicking myself, but I can fettle properly once its all assembled.  Next step: BB & Cranks.  Then brakes, gear cable, bar tape, chain.

The JTek 11-spd lever is nice, but really quite large.  I had to reset the angle because I found it clashed with my (reversed) brake lever movement.  It won't be pretty up the front end, but it will certainly be functional!

The blue is so dark that it is hard to see the difference under artificial light from the black headset. :)

I got my Raleigh 531 frame back from the blasters today. Before:

While I love the way that the brazing looks, the tube surface is a little rough, so it needed a primer before the main event:

Sanding tomorrow, hopefully followed by some of the detail spraying.  :thumbsup:

;D I have failed to grow forks for many years, but this years crop looks OK.  :thumbsup:
I sprayed it in the improvised booth in my garage (holding the steerer tube in my hand), but a stick stuck in the ground is the easiest way to hold it up while drying.

PS
If anyone knows a good way of spraying it so that the stamped "Raleigh" on the seatstays is a different colour to the rest of the seatstay, I'd love to hear it. It shouldn't be too hard to do with a brush, but the spray.bike stuff isn't brushable.
Cheers

Fill the letters with some removable substance, then apply a second coat?

I'm not sure what removable substance I can use that I can pick out without scratching the underlying paint. Someone else suggested I just spray on the dayglo stuff after I've done the base colour and then wipe the surface - so long as the wipe is flat enough it shouldn't drag the paint out of the indented letters. Not made my mind up yet.

Today I sanded it lightly, ran a tack cloth over it, and then added the dayglo bits.
First, the blue:
IMG_20171028_172349 by duncancmartin, on Flickr
IMG_20171028_172400 by duncancmartin, on Flickr

I left it a bit and then added the orange and the pink:
IMG_20171028_174647 by duncancmartin, on Flickr

I put pink on the inside of the chain and seatstays, and orange down the back of the seat tube.
This all looks very bright and messy, but the idea is to wait until it's all dry, and mask it all up. There will be a 1cm width line down the middle top of the top tube and one a little bigger along the middle top of the down tube. Similarly the rear triangle will get masked up with thin tape on the inside of the chain and seat stays, and chunkier tape down the middle back of the seat tube. Hopefully, it will end up being relatively neat and subtle once the plum is on everywhere that's not masked.

I have 1 remaining issue - the original head badge is knackered. There are 2 holes in the head tube that I need to fill, either with a new badge, or with a plug. I need to think about hos I should do that. I guess I could leave the holes there and just use a sticker, but I'd rather use a neat head badge.  Maybe I could just paint the original with the neon and then epoxy it on (the clips came off the back of the pins that go in the holes).

I'm not sure what removable substance I can use that I can pick out without scratching the underlying paint.

Hmm, how about some sort of wax, that can be melted out?

I was originally thinking something like vaseline. Then, once the extra paint is applied, I could poke through it and clean the indented area out relatively simply. Wax is probably easier to clean away when there is overspill while applying, but I'm not sure how well the paint would react if I'm heating the frame up enough to melt the wax out.
I have some spare tubing kicking around, so I might give it a go and see how well I can wipe off one paint layer while saving the other one...

Forks done. I need to mask up the frame and paint it tomorrow (and then clear the both of them).

The finish isn't as smooth as I would like (nor as smooth as the primer was after sanding), but I think the masking worked out OK. I think masking the frame is going to be harder...

You could try blu tack or plasticine, I'm sure I've seen that on Blue Peter some decades ago, though probably not a bike frame.
I'm interested to see how the frame works out, looks OK so far.

Play doh? Silicone sealant? Wax is the obvious one, as others have said.

I had to add a bit more coverage in a couple of places, but after that, I masked the frame up:
IMG_20171029_140330 by duncancmartin, on Flickr
Including the complicated rear triangle masking:
IMG_20171029_140339 by duncancmartin, on Flickr
Then I hung it on the washing line and sprayed it:
IMG_20171029_144425 by duncancmartin, on Flickr
IMG_20171029_144441 by duncancmartin, on Flickr

I then had a great idea of lining the lugs by spraying it into a yoghurt pot and then using a brush. It seemed so simple when I was practising on a spare tube, but then I did it on the fork and screwed it up  ::-) :
IMG_20171029_145510 by duncancmartin, on Flickr
I guess I'll have to mask up the inside of the forks and re-spray the crown again. :(  :-X
I'll update this when the frame comes off the washing line, and we'll see how the concept (and the masking) works. It might even mean I can change the crown colour to blue.

Blue tac is a good idea. I was thinking about having blue writing with the plum stay, but depending on how it looks when the masking tape is off, I might try having plum writing, with blue stays...

I went to get it down earlier, and discovered that I'd missed a few bits from the back of the frame. So I took the line out of the head tube, hooked the rear dropouts over the line and sprayed all the bits I had missed earlier.
I've just got it down from the line and removed the masking tape. Well chuffed with how this has turned out:
IMG_20171029_181156 by duncancmartin, on Flickr
And this is what it looks like with the forks:
IMG_20171029_181354 by duncancmartin, on Flickr
The blue and the pink works really well with the plum, but I'm not so sure about the orange.  Just as well it's only on it's own on the back of the seat tube. :)
I'd still like to pick out the shapes of the lugs and the stamped in Raleigh on the seat stays (but I don't think I want to make the whole flat surface of the stay blue or pink). I think maybe I should put the clear over it now, and think about adding details. That way I won't mess up the existing good stuff...

A frustrating week off work sick made a difference to the build!

Can't post photos here atm but it has most of the basics.  Awaiting a light bracket, some cabling (electrical and gear), bar tape, mudguards and (maybe) a longer stem. :)

Lots of dark; lots of shiny! :)
