Oi Kaiser, ZigZag and me were going secret trail hunting at Glentress on Sunday if your interested. Alternatively maybe we could join you at the Drum if ZZ happy to go again

I tried a bit of that mountain boarding due to Dave's encouragement. I didn't enjoy it, until you get the hang of it you fall over alot and unlike on snow it bloody hurts even with armour on :shock:

I measured up my Nishiki frame against my already huge Hardrock. Blimey its HUGE, the Hardrock seems petite in comparison, no build plans yet though, I'm trying to be good and get the Falcon built up first as per original plan :roll:

Great photos Dave, I'm heading out on the bike for the first time in 6 weeks tonight, If I feel fine I might manage some kind of trip at the weekend.

looking forward to seeing the "big" frame velo- have a great one whatever you end up doing- off to sisters sat. so no can do sunday wifey time, :cry: look after kaiser for us

 

[kaiser]

Velo its up to you and ZZ but again I'm time limited. Looking forward to seeing the nishiki, nice bike

Gaz, been thinking, using my scientific mind and come up with the reason the insides of your frame are rusting.

Inside surfaces of the tubes are unpainted and exposed to air as the frame is not airtight. We live in a damp country with lots of moisture trapped in the air. When the bike has cooled say overnight, moisture in the air has condensed on the inner surface of your bike tubes. Result moisture + air + steel = rust. Unless the manufacturer coated the inside of the tubes all steel bikes in climates such as ours will get a wee bit rusty internally

Steel has tensile strength, less brittle than alloy, unless a crack is present it will bend often slowly before it snaps. You should get some warning if the frame has been weakened by rust which I seriously doubt

@Velo - I'm still planning to be up on the 20th.... might even drive and bring the 'dale if flight prices don't drop.

Sat 21st or Sun 22nd - Which date is better for a wee cycle?

[NB Crazy Al's 40th on the Sat nite so may be a wee bit off colour Sunday].

If I do fly which bike would you risk snapping under my svelte physique and graceful style?

Would love / like to meet some of other MacRetro crew as well.

Cheers M.

I dig your thinking Velo and pretty sure your right on the money- most of the rust is in the bottom bracket which has no drainage hole but the seattube has a hole at the bottom- water coming in via the seattube clamp would just pool there. And the other area of rust concern is in the wishbone rear, and there are two open holes on the top sectio- just like Kaisers derkerffy bike and it also has holes in all the stays close to the drop outs- think they needed these when they were brazing the dropouts on for some technical reasons I do not ken :roll: anyway, a good frame builder would plug them but this is an orange Think I will plug them up once she has been treated and protected- in the light of day and with lots of positive vibes and google time, I think this could turn into my replacement main rider. Thinking of classic matt black prestige with orange decals whatdayathink?

 

[kaiser]

Gazz you are indeed correct the holes are to allow air to escape when welding. As you weld you heat the air in the tube which expands, if it has nowhere to go it will either blow out the weld or limit the penetration of the weld.

 

[velomaniac]

Gaz, go for it, seen one just like the picture and it was well smart !

cheers folks I will get a thread sorted latter tonight

I better go clean the house before the good lady returns, least she thrash me for my slovenly ways
