So the next 3 test pieces I turned down the oxygene just to the point where the flame goes from blue to yellow . And then back a bit , a tiny little bit on the blue side otherwise I wouldn't see anything . And then like magic .... look at the pictures .

Guys , what can I say ... I'm speechless . Friend of mine who's an hvac technician gave me 5 rods . He said he bought it years ago , tried it and couldn't get it to work . So this evening I reluctantly did some test pieces , using an acetylene / oxygen torch as a heat source . Expecting...

Quite odd then that it didn't smoke on your first attempt , and now with basicly just a thicker headgasket it does .

I have flaring tools , but that doesn't work on thin walled alu tube . It'll work , but won't last long , especially in a car . Swagelock's won't work either , the material is to soft for that . Soldering or brazing is the only way .

Guys , I 'm call on this list's wisdom . I need to solder or braze an aluminium AC condensor . The person who removed it couldn't undo the nut at the condensor side , and decided to twist it until it broke off ..... at both ends . The tube wall thickness is 1mm ( 1/32") , and altough I...

As an illustration of what a gear pump is capable of . I once made a mistake installing an oil temp sensor on an 136Hp audi 5 cilinder engine . That sensor replaces the bolt that holds the pressure regulator spring in place . Part of the regulator was assembled backwards , basicly disabling it...

A relief valve at the discharge of the pump to limit and stabilise the oil pressure . Thinking of a T-kind of piece at the discharge end of the pump , with a small ball and a spring . Pressure can be adjusted on the bench before assembly . Combine this with a restriction , like a needle valve ...

A good load for this would be an ac generator . The rpm determines the frequency , wich is usually 50 or 60Hz . Then the alternator could be loaded with an ac motor or some light bulbs and the governor would have to work to maintain rpm . Great work brian

Nanocad has been suggested to me by a couple of friends . I'll give it a go for sure , but I'm a bit worried now that someday thesame will happen . Does it also need an online activation , I don't know . But if it does I guess I won't take any chances . I want to limitthe drawing time as much...

Glad to see this beautifull project is still evolving and improving . Pat

Nice , governors have always been a bit of a "dark area" to me . They work , or they don't work ,on lawnmowers that is , but that's about all I know about them . I'll be following along , and beautifull work as usual brian .

"Nope. Mr. Pete in a video acknowledges he isn't the Tom Walshaw "Tubal Cain" Yes I've seen that video to . He mentions a british gentlemen who wrote several books , and then says offcourse that isn't me , that is another tubalcain

I have tested several laptops , wouldn't believe it doesn't work on a laptop . It's true , timing is all over the place . Tried disabling power control scemes , tried running a lite version of windows XP . Nothing seems to work . BUT , then I found a fix . Found it on the net , din't invent...

Quick question guy's , is there a general concensus on wich pins to use for step and dir ? D3 D4 D5 D6 D7 D8 D9 ( pins 4 ...10) are sed by the shield if I understand corrctly . D0 D1 ( pins 1 &2 ) are -sometimes- used for serial communication , so better to avoid also . That would leave D2...

For a milled pcb you board looks very clean . Most of the time marks from the cutter ruin the looks of milled pcb . That doens't affect functionality tough , its merely cosmetic . But yours looks as good as an etched pcb . Nice work ! Just wondering , why did you put the parts on the...
