King C Posted August 29, 2007 Report Share Posted August 29, 2007 (edited) So I know the two halves are cast aluminium but how mare they then joined together to create a water-tight seal? I should use my brain but I just dont seem to be in the mood for thinking after 5 weeks of not having to.At the moment all I can think of is brazing but can anyone clarify this? Im pretty sure its not welded.They must be joined as two halves as the piston neededs to be put in before they are sealed.Also what type of casting is used? Im guessing investment/lost wax as the inards are quite intricate.I may also put any other magura related questions in here as Im sure to think of some.Thanks in advanceKing Edited September 1, 2007 by kcchan Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted August 29, 2007 Report Share Posted August 29, 2007 i just had a look at mine and i can't see a join....where are you looking?if this is a dt project- i'd look at reviewing all the different types of casting (gravity, die, lost wax etc..) and saying which is best for magura (mass production)....ooo they love all that stuff.

King C Posted August 29, 2007 Author Report Share Posted August 29, 2007 (edited) i just had a look at mine and i can't see a join....where are you looking?Edit: I lied.erm. looking at the side of the cylinder which has the logo on it (assuming you havent sidehopped it off), there is a join running all the way along. It goes between the two holes at the top, down the side, between the biggest gap made by the prongs and then back up again.(the worst description ever)I think what Im looking at it just where there was a gap in the mould.if this is a dt project- i'd look at reviewing all the different types of casting (gravity, die, lost wax etc..) and saying which is best for magura (mass production)....ooo they love all that stuff.Yea will do cheers for thatSo what type of casting is used for maguras?

Heatsink Posted August 29, 2007 Report Share Posted August 29, 2007 I'd say simple die-casting (with the split line between tool halves appearing as a raised line on the part) followed by machining the accurate features such as the inner cylinder bore and the threads.Steve Quote Link to comment Share on other sites More sharing options...

Tony Harrison Posted August 29, 2007 Report Share Posted August 29, 2007 Yes, simple die-casting. No 'lost wax' needed here. Also, they don't have any welds on them, and if they did, it wouldn't be brazing, which is used for steel. I think they have inserts for the cylinders, bronze or brass or something as it's harder-wearing. These would be an 'interference fit' and pressed in.The best process for Maguras is die-casting (which is why they use it!), but obviously you'll have to discuss this in more detail and say why it's more beneficial over the other processes.

King C Posted August 30, 2007 Author Report Share Posted August 30, 2007 New question, when were HS11s and HS33s released? I know the HS33 lever changed in 2005. Quote Link to comment Share on other sites More sharing options...
dave33 Posted August 30, 2007 Report Share Posted August 30, 2007 1993 i think Quote Link to comment Share on other sites More sharing options...
JonMack Posted August 30, 2007 Report Share Posted August 30, 2007 (edited) Magura started producing hydraulic brakes for bicycles in 1987, the HS33 was released in 1997. Edited August 30, 2007 by MonsterJ Quote Link to comment Share on other sites More sharing options...

JonMack Posted August 30, 2007 Report Share Posted August 30, 2007 (edited) http://translate.google.com/translate?hl=e...fari%26rls%3DenSince 1987 Magura produces hydraulic Felgenbremsen for bicycles.For Mountainbikes and Trekkingbikes there are the following products of Magura (in qualitatively descending order):HS33 Race LINE (CROSS Country)HS33 (route, CROSS Country)HS24 (no longer available)HS22 Race LINE (CROSS Country, no longer available)HS22 (route, CROSS Country, no longer available)HS12 (no longer available)HS11 (route)The above-mentioned models are to a large extent identically constructed and differ only by its colour and small details like the weight-reducing aluminum screws of the RaceLine models. The brake grasp with the integrated master cylinder was only sketched in the course of the years several times again - only by it e.g. the Urmodell HS11, year of construction 1987, from the first HS33, year of construction 1997, or a HS11 or a HS33, year of construction differs 2007, from each other. There was also a number of different Brakebooster, which differed to the function however only in the form, not. The new Evo2-Adapter, successor of the evolution adapter for the faster assembly of the brake cylinders on Cantilever bases, is completely downward compatible, i.e. also a Magura HS11, year of construction 1987, could be equipped with it.

King C Posted September 1, 2007 Author Report Share Posted September 1, 2007 (edited) How Are Barbs, Shroud Nuts, Olives ManufacturedIm thinking turned o a cncd lathe, then with the shroud nuts and barbs, just machine the faces off.Any confirmation?
