What gets me is why the transformer manufacturers dont use at least a striped and solid wire for each winding showing the phase. All the phase is, is the start and stop of each winding where in paral

Marv, Well, they're getting cheaper, no screws now! Does the lams still have the screw holes or are they solid? A 1/8" fillet weld wouldnt be too hard to cut out. The problem with welds here is causi

As a rule of thumb, the kraft paper thickness is rated at 2 mils thick for every hundred volts. If one can get to the paper to check the thickness with a mic or caliper, they can see if it will hold

I've never seen nor heard of a 1/4-23 thread. The standards are 1/4-20 NC, and 1/4-28 NF. I don't know of a lathe that would turn that either without a special gear being made for the feed, if that's

It might be conceivable to cut on a CNC machine if the carriage moved by it's own power and not a lead screw using an encoder to tell where it was at. Special threads like multi-lead screws are gener

Marv, 20 kilogauss is even over the maximum flux density of Hipersil or M-6 which is 17 and recommends 15. M-2, the best is still 17 kg. I'd say that transformer is running into stauration under full

See, that's a shame. If I recall, those vernier dials are 8 revolutions per turn of 360 deg., and dial counters are set up for 10 turns used on ten turn pots. The old National verniers, I cant recall

Rich, I'm not sure, but you know as me that lathes have only certain threads possible by the gear ratios in the quick-change gearbox. Most I've seen that you can do is the standard or metric threads

Al's correct. For any who want to try it, the way I used to chase threads on a lathe was as follows. First, mount the shaft and bring it into round with your dial indicator using a 4 jaw chuck. Next,

That could propose a problem, especially using tool steel. A carbide insert though will cut it. The only thing is you have to take a deeper cut sometimes as something will give when the tool meets th

Marv, I can see what they're doing, probably running the transformer and tube maybe at 25% duty cycle by pulsing it. The thing is, even doing this, the transformer is going into saturation most likel

Dan, Increasing gain can be had by resetting the bias if the transistor can stand the extra current through it. Also, you have to watch and not overload the stage ahead of it. However, you said it di

Tomm, That's what I was remembering that they were actually regulating by using a ferro-resonant transformer (using a shunt). Without the shunt of course, you have a regular EI core, or close to it.
