Just finished moding this Miyata 610 . Upgraded most of the running gear including a nice set of Suntour side pull brakes . converted to upright bars and thumbies for a classy urban cruiser.

At the moment I am painting 3 bikes. One is a Schwinn world Sport that had a dent in the top tube that I finally rolled out with the new frame blocks I just purchased for the shop. the second is reputed to have started life as a raleigh Professional but has been modded so much it is hard to believe it still is. It also had dents in the top and down tube which I fixed. The third is a Novara junior tri bike with 26 inch rims carrying 26 x 1.125 tires with 2x8 spd brifters on an aluminum frame with a HEAVY Steel mtb fork. painting is going well with all but the Novara finished. will show pictures later.

Raining today so more inside work, a little more progress on the strippage of the 620. If it's hot and sunny tomorrow I'll move outiside and try merziac's suggestions for further paint removal.

It needs to be pretty warm for the drastic results, a "hot box" on the ground, wood frame or tub, pool of some sort, black plastic and a clear lid, glass or plexiglass may be needed.

The big wire brush is a big part of this so you can really lean on it without hurting anything.

Preheat will speed things up.

My back storm door has glass panels that can be taken out and used carefully for this.

Timing is a bit crucial ime, you don't want the first slather dry before applying the next one but if its not lifting noticeably, it will be slower going.

Picked up frame from power coat
Some more pics on this old thread.

Started assembling the modern vintage steel bike.
Now I have plenty of clearance between the tire and seat stay bridge- as seem Conti GP5 32c.

I have been looking into frame geometry and sizing to see if I could possibly improve on my touring bikes. Found a dilapidated '85 Koga-Miyata frame in the attic that I'd saved from the dump many years ago. 63 x 57 cm, with a 72° seat tube angle. I removed the rust and gave it a quick once-over with a rattle can to seal it and make it (somewhat) more presentable.

Been mocking it up today, to see what it would look like, and what kind of room for tires and fenders there would be:



So far, so good. But it will have to compete with my Roy Thame. Will the Dutch-Japanese alliance beat England? Stay tuned to this channel ...

Sort of in the home stretch, though cabling the rear derailleur (it’s internal through the chain stay) will probably chop quality years off my life.

Black hoods fit a bit better than beige ones I had, but apparently this generation of body is slightly different than the classic Superbe lever. Sort of tempted to use the classic drilled.

Wheels are trued (to the limit of my skill) and the Mavic 550 hubs are silk. Decided on 25s but I can always go 28s if my teeth rattle out and they will clear the brake.

Adjuster screws set, wheels on and ready to do some more a bit later.

Still to come...Arubdel Gecko bar tape, black cables I assume will do it for this look, front derailleur and chain. Plus a Terry Liberator titanium saddle.

Edit...oh yeah, and brakes.

^^^^^^^^^^^^^^^^^^^^^^^^^^

I love the details on the Trek, but they obviously employed Satan to design the internal rear derailleur cable route...

Very heavy lift going up against RT IMO, he would have to have a cracked frame for the KM to get in the game with me.

Nothing against the KM's, we all know they garner otherworldly love from many.

As Mr. Moulton would say, "Not bloody likely".

New Here, I just picked up a very good Condition Trek 300 off an older neighbors yard sale for 5$! Ordered new Tires, give it a tune up, and new Handlebars. Pics coming when I could post.

Thought I’d also put this here. 1985 Trek 670 done! @Mad Honk

Yes, the Roy Thame is a fantastic bike. Probably the best I'll ever own. But if I'd call it quits, I'd be out of a hobby. Now, we don't want that, do we?

merziac

No, of course not and the KM can always be a backup, poor weather, etc plan.

I have a few jobs in rotation while I slowly nurse
my knee back to some level of comfort. One is tweaking the Motobecane Grand Jubile into readiness for Mrs. ascherer.


I found the Rene Herse 32s I overzealously tucked away and used the occasion of mounting them to true the replacement wheelset and swap out the corncob that was on it with the the 14-32 Maeda that was on the Moto when I got it. The chain line isn’t great and the long cage Jubilee drags in the 32 so that gives me more tinkering for another weekend. I’m putting Tektro levers on for my wife’s small hands, and by next week I’ll have fresh tape for the bars. It’s all a test - I think this bike will end up with an upright setup eventually, but one step at a time.

I’m also stripping my Falcon for a repaint. Each weekend I do another round of CitriStrip. Most of the paint is gone now but the lugs and bottom bracket still need attention. Now that the frame is bare I’m appreciating the simple and clean work done some 50 years ago on this frame.

My knowledge of frame building is pretty limited, but I observe that the lug points were nicely thinned and there’s not a lot of visible brass hanging out of the seams except where it was used as an integral part of the wraparound seat stays.

Finish putting together the bike today, no test drive yet.

Today it was my turn with Cuda Kurt's Raleigh professional! I'm thinking he is gonna see this and think he should have called on the Bike Butcher of Portland. The frame showed up with visibly damaged ears for the seat binder which required more metal than was there. So, off I go to the race car shop and we get out the welder to give some needed reinforcement material. I am not always very gentle with the addition of welded material as the photo's will show. The ears are now flat and ready to test my metalworking skills. I'm thinking that the ears with the added material may require a slightly longer binder bolt, but that is a small price to pay for the added security of a good strong weld. Kurt I hope you approve of my work! Pics:

There is a lot of welding material added to the ears, but I can remove some easier than I can put more on.

The other ear and excess material added to it.

This is butt ugly after the welding work, but wait until I can get the ears cleaned up.
This kind of work always requires a lot of bad before any good shows up. You can see I got the paint around the lug a bit discolored but the guys at the Professional Refinishing Shop have matched the paint to the original so only priming and painting of the top tube and lugs will be required. I will post more as I get a bit farther along with this repair. Smiles, MH

Mad Honk 

Today Cuda Kurt's ears have been cleaned up and they are a bit better than yesterday. Some rain in the forecast so they have a quick shot of clear on them to prevent rust. Cleaned and ready for paint prep:

excess weld removed

not the rounded stamped that was factory but a bit more substantial

a lot of hand sanding before primer goes on but thank goodness it is only the top tube that needs it
Smiles, MH

Waterford RS-12.
Pics when I get it out of the truck.

A rehab/tune up surprise project. They're on vacation.
I'll rehab their bikes and then hand them back in the same spot.

More fun than house-sitting.

Just finished working on my first "Fat Bike" a Mongoose Beast. This is a pretty basic coaster brake bike with one exception It is HUGE! all up and ready to ride per the attached photo it weighs 49 + pounds. The wheels and tires look like they belong on a model T Ford. The frame crank, bars and everything else is steel .

Taking it apart it was quite a lift to get it up on the stand and when removing the wheels I had to brace myself for the weight . The tires were in good condition so I didn't try to remove them . To be honest I don't know if I could have.
The bike had been to Burning Man a few years and when I removed the head set the bearing grease looked like mud and probably was. They cleaned up o/k though.

Getting the crank arms off was a chore. I was able to remove the drive side and pull the spindle out but the nut holding the crank arm was frozen. A few days soaking in Kroil didn't budge it and when I tried using a breaker bar the socket slipped off the rather thin nut so I took it to the shop and used an impact wrench on it which did the trick. Luckily I didn't damage the spindle because it is a specialty part, about 2 inches longer than anything used on a regular bike. I wonder where you would go to buy that part? I didn't take the rear axle apart but did service the front. Again mud . No pitting though so went back together o/k. The only real changes I made were chrome handle bars, new grips, and a new saddle. The front wheel spokes were prety rusty so I rubbed them with 0000 steel wool and sprayed them with black paint. The frame was in good shape and a quick rub down with white polishing compound did the trick. The tires and wheels were washed and treated with Armor all and here is the result .

Mad Honk 

I'm beginning to think Kurt's bike frame has a life of it's own. After repairing the clamp ears and reshaping them it was time to tackle the "Patina" on the top tube. About two hours of steel rust removal and paint clean up on the top tube and It got a first coat of sealing primer. A bit more of finish sanding with water paper and then hoping I have the paint mix right to actually match the 30 year old sun-bleached paint. After today's work it looks a bit more like a bike and not a rust bucket.

The front lug was damaged by a spray bomb paint job and could not be brought back to original paint without damage, so It will be recoated. Top tube underside where rust blooms were forming, after mitigation and primer coat.

The ears came out fairly clean and a couple of pinholes in the welds were tidied up.

There was a large rust area about four inches long on this side of the top tube. Totally removed and ready for final coatings.

If that rear derailleur gives u too much trouble I have a competition it would work well on. Don't want u to worry over it too much!

ascherer 

You’re too kind!

I'm here to help!

It has sort of sidetracked me from various projects but has been fun overall. until I come up with a better garage configuration I cannot store finished bikes...so 8 or 9 bikes go unbuilt.

Fifth and final...was an afterthought when this teacher and the teacher getting the Giant told me they were going to NorTh Carolina and would love to ride around. So jdawg moved it up in queue. Not as fun but should be fun. She loved it in any case.

amazingly, I still have a bundle of giveaway bikes from last year. It’s like a never ending pile. I think I bought too many...
