Holy smokes Sam !!! That's a huge project, anyone but you I would say didn't have a prayer of completing it. Having seen a lot of your prior work,...

Thanks for posting that ! I knew you could hot wire a PC supply and they make nice bench supplies BUT that board is so cheap and makes for a nice job....

[Sparky_NY]

Not a book but Strictly IC magazine was a wealth of information as well as many examples, some with plans. Sadly they are not published anymore but back...

Depends on the particular switching supply. I have a RF45 mill that is retrofitted to cnc. It has a 48V switching supply (HP server supply, 3KW)...

A lot of users, home shop and otherwise do indeed use conversational for SOME jobs. Problem is that conversational has its limitations, 3d profiling...

Iron pipe for hydraulic is seamless unlike common black iron pipe. Hydraulic pipe fittings are also different. It would be easiest to just run hoses,...

The voltage they generate is proportional to the speed they are spun at. So, for example if you spun the 10K rpm one at 2500 with your drill, it would...

[Sparky_NY]

A perm magnet dc motor works as a generator if spun with another motor. If you know the rpm of the motor in question and spin it at that rpm it will generate...

I once had a snowblower that had that cross hole worn oval and kept breaking the drive pins, in was IMPOSSIBLE to drill a new hole, the bore is recessed...

[Sparky_NY]

Many snowblowers have a cross drilled hole in the rim which is used with a pin to engage that wheel to drive, goes through the rim and the axle. That...

Yes, of course but the timing of the intake valves is equally as important and just because the lobes are "fixed" does not necessarily mean...

[Sparky_NY]

There is 2 valves, right? Why no mention at all of the intake valve timing?

[Sparky_NY]

Variable valve timing AND variable lift are getting more common these days on autos. Unfortunately, the behavior is controlled by the ECU (engine control...

[Sparky_NY]

The issue is going to be advanced, or retarded from WHAT ??? Those rules of thumb you read probably are referring to auto type engines where there is...

Cheap bastard, buy some fresh bread and you won't need the bandsaw...

Nice job building that ! When I seen this thread I thought of the hydraulic chainsaws I have seen on firewood processors and also those mounted on excavators...

Wood dried still has somewhere around 15% moisture content and is a very poor choice for high voltage insulating. Ignition coils normally start at about...

Flowing propane through pipes while getting them red hot brazing with a open flame, what could possibly go wrong ??...

[Sparky_NY]

Yup, standard practice. There are pinhole openings in areas of a system plus its like having sand in your motor oil, very bad for the compressor, definitely...

Any updates? Too tight to run?
