It's very interesting Chris, they use water and a fine glass slurry as abrasive material to blast. It's so much less abrasive than conventional sand blasting that you can even blast a piston without losing any tolerances so it's perfect for those thin tubed bicycle frames. It's very popular in motorcycle restoration for cleaning aluminum parts.

I see a few DIY options on YouTube .i will try make somthing see how it goes.

Was watching the same videos last night .... 

 

I am familiar with sand blasting, then media blasting, then shot peening ... all for less "damage" during the cleaning process.  This certainly is a nice next step in the evolution ....

 

PS - at one stage they did research on "shot peening" to actually strengthen the outer layer, as apposed to damaging it .... not sure how that ended.

Hi, does anyone have one of these they want to sell? "Double cable stop" for converting vintage steel frames to handlebar-shifters without shifter-mounts on the down tube?

or a DIY hack I can do in the meantime?

thx

Thank you, sent Brett a message ... this is the frame I'm busy with. A middle-of-the-range LeJeune, think it's from 74'. 
It doesn't have any water-bottle bolts either ... just gave it a quick sand-down, primer, and colour. 

Want to join my friends on their gravel rides ....  ... and might use it for commuting too.

That is beautiful; I could almost see a vintage Brooks saddle on there, rather than, er, that GREEN ‘thing’…

nice bike!

😂😂 yes, that green saddle is really hectic, I should contact Gareth again at Velobrien to cover it for me in brown leather. He has done other saddles for me in the past, and they came out awesome.  🙂

Agreed, Velobrien is the place to go. I do all kinds of leather stuff myself, but I take my saddles to them. Always awesome work.

Pity you aren't JHB based, could have assisted with adding some rivnuts for bottle mounts, if you don't mind drilling the frame that is.

steel is so cool that you can ride with a back pack full of water bottles.

So the retro gravel build is nearly done, I have just run the housing all the way down for now.

I've replaced the rear derailleur with  an old XT 9sp. Beautiful thing about 9 sp is that all MTB and Road groupset components are interchangeable. So the 9sp 105 STI works perfectly with 9sp XT derailleur to give me space for the 32T in the back, might even take it up to a 34T or 36T if I can find something cheap somewhere. 

Got an Adamo Peak saddle for 100 rands on bikehub to replace the "green thing" .... 😁

The chain on the 11T cog of the cassette catches the frame, but with a 53T on the front the 12T is fine for now. I just adjusted the stop-screw to stop at the 12T.

... just need to tubeless the 38c tyres, then I'll head onto gravel somewhere

(future change might include another crankset?) .. but very happy to use as is 🙃

Is it just me, or does your saddle look a little odd on an otherwise-beautiful bike? I get that it is better than the ‘green-machine’ saddle you replaced it with, but I don’t think it does ‘justice’ to your brilliant bike!
my 5c, leaker project!!!

…and what plans do you have for a water-bottle mount? Clamp-on style, or how?

I bought an extra pair of hinged 28.6mm water-bottle clamps from CRC a few months ago. Will use them.

(i hear you about the saddle, not very aesthetically pleasing   😉 ..... but I am comfortable on the Adamo range. All my bikes have them, and the Adamo Peak was the only Adamo I think is appropriate for a gravel bike? .... that would flex enough?)
