Mystery Dyna Tech?

[drystonepaul]

Having spent the last couple of hours with a hairdrier and solvent removing the remnants of stickers, and cleaning off several years of grime, I can confirm that there are no more stickers hidden under the paint.

The rest of the paintwork in general is in a poor state so it'll most likely need a respray at some point.
Next question then; bearing in mind this is a bonded frame, would using paint stripper be a bad idea? Also how do we think the bonding would stand up to the powder-coating process should I choose to go for that option?

Thanks again for all the input so far.

In no particular order, I'd say No and No to both questions. I don't know what it was, but Dynatechs used to come with a release agent to unglue the tubes from the rest of the frame, without knowing how close that was to Nitromors I wouldn't risk it. Powder coating involves sandblasting, then powder coating and baking the frame for an hour, I think you're asking for trouble.

This could be a good candidate for a "q-bike", a fast but ugly bike you can leave in town that will knock all the other commuters into the weeds. I've got a Saracen I'm giving that treatment to at the minute.

Have a look for a bike I used to own called Jimmy Saville's Mtrax.

I'm aware of the jangle jangle M-trax. Good bit of work there Chris.

With regards to the questions about bonded dyna techs, I thought that both answers would be no. I asked the question to comfirm my initial thoughts.
Should I still choose to though, what would be a good way to strip it?

I need to remind myself that the whole idea behind getting a cheap frame was to build up a fast winter hack, albeit a period correct one, using some slightly tatty DX brakes, mechs and cranks, along with some haggard looking XT thumbies I've got knocking about. I'll build up some DX hubs with modern rims and tyres, so that the sound of the gritty grinding paste we know as our brakes in winter doesn't make me cringe too much.
I have to keep telling myself not to go to too much trouble with this bike and turn it into one of those bikes that I worry about damaging when I'm riding. :roll:

Still, it's looking a lot better now that I've managed to clean off most of the dirt. Still got a good patina though. The potential problems I've discovered along the way are that the headset cups are loose in the head tube and there's a bit of chainsuck damage on the chainstay.
Oh and the BB is of course seized in the frame. Pass me the Plus-Gas...

I'd give the existing paint a good rub down and smooth over then use it as the base coat for a rattlecan respray. Keep it cheap and functional, dont overdo it. You may have to shim or glue the headset in so make sure its the headset you want in case you cant remove it later

Not all Dynatechs need to be showroom restorations, its the riding that counts in my book

Nice find, should build up very nicely with the DX kit your planning to use

...what would be a good way to strip it?

in answer to this question, since you don't want to use any sort of paint strippers, you might want some pointers from StarTREK using razor blades ein?

the bridgeless chainstays all tie in with the titanium bikes in the 1992 catalogue. (My only reference point)

So can anyone offer up any suggestions please?

Mine has a half bridge between the chainstays and the chainstays are bonded into the bb (cant see on your pics), other than that everything looks the same...

Cheers velo. Good advice and totally agree with your last comment.

Dear god! Razor blades!!? I was hoping nobody would mention this. :shock: Thanks for the suggestion ER

Thanks for this too Dave. Mine has bonded in chainstays, but no bridge whatsoever, There are also no mudguard or rack eyelets on the rear dropouts on mine unlike the ones I see in the photo of yours.

These minor details however are probably just another UK frame building anomoly. I'm used to that from Saracens.

Excellent find! :x

If you want to get the paint off you could get it shot blasted but tell them the situation with the bonding and they will stay away from the joints a bit.

Looks like a de-badged 92 Diablo to me. Frame no also indicates this year.

Be careful when you have it painted... Because the tubes are bonded it is best not to expose to an oven as it could have a detrimental effect on the adhesive material, especially after all these years.

Build it up with some nice period kit... they really do ride very well, I have had 3 now.

Keep us updated.

Cheers,

Chaser.

I can't believe I've gone since mid-nineties without seeing another '92 Diabolo DX, join this forum and immediately two other people have one.
Awesome!
