Lots of replies here so I will just answer in a general sense.
Also sorry I did not do a search on this problem not realizing it has been beat to death.

All I really need to do is find a 50 amp...

Scottl was typing as I asked the question.
There are 5000 types of NTC thermistor listed on Mouser electronics...the good news is that they appear very inexpensive if only I knew which type to buy?

Two questions, if the breaker is designed to break easily and does so when switching on the transformer why does it hold if I reset? Often once will do it but usually have to reset twice.
Second,...

Wouldn't the making of the drawing and then making the block be the school project?
I made my own after looking at the images of the blocks in the Diacro literature.

Stros,
Thank you for that info. I relied upon my electrician to buy the breaker. I believe we both thought that starting a transformer was not a big load therefore didn't need any special kind of...

Scottl,
Thanks for that clear explanation. I understood the first part but not the second.....
Not sure why the manufacturers need to “improve” things all the time.
Luckily it is only 20 feet to...

Thanks for the fast replies.
I could power this through a fused disconnect but the panel was working fine with the exact same setup with the 30 amp breaker.

Not sure how to test the trip curve?...

I have a mystery problem.
I have 120-208 volt three phase coming into the building.
I installed a 120/208 to 480 volt 30kva transformer to run my large roller.
At the time I installed a 30 amp...

Garwood,
Not sure why you would say CNC only?
I use my morse taper bilz floating tapping head in my drill press quite often. It works very well. I also used to use a straight shank in my turret...

And one more photo.
Not all the dimensions are critical, the back pointy section is but the front is not given that the nose clamp is adjustable.
The point fits into the notch in the dowel and...

You bet!
Here are some photos with dimensions.
Of course the centre hole is 1" in diameter.
I made the nose taller than normal but 1.5" would be the stock size.

I did some very curvy chair backs in the vacuum press and I can say that the seat form in one piece would have been easy compared to my chair backs. I had to go very thin with the hand cut veneer...

Very nice!
Just used as a drill press it will pay for itself in its versatility.
I sure hope that cabinet full of tooling included the porthole cutter!
A really interesting design and I had not...

It looks like your cutter is performing well except right after the tab if I understand correctly.
Could you try and move over 1 or 1.5mm after a tab and cut for 75mm, then come back and recut on...

Gary,
I did the welds with the 200, I don't have a water cooled torch at the moment. I have the torch but no cooler.
The air cooled torch does get a bit hot after doing most of the welds.
What...

Anyone seen any packages yet?
So far I have not heard from anyone except Cyclotron and he did not get his package.

Stros,
Thanks for all the info. Very nice setup you have there but almost a bit too much like an operating room.....( I like a bit more chaos)
Which welder do you have? I can see it in the photo...

Some very well written posts here. Thanks to all.

Ferretlegger that is exactly the info I was hoping to find here on the PM.
I have seen a few Dynasty welders for sale but did not know how good...

Ries,
Which tig machine do you have?

WoodsR,
Model and brand of new double pulse?

Jamscal nailed it. Chairs.
Lots of welds, lots of repositioning, not large, needs to be strong and pretty. Some welds will be ground down flush, all fillet welds will show.
I am fully prepared...

I have a possible job welding some 1" square tubing, .125 thick, lot of small short welds to weld all the pieces together. Mostly fillet welds and lots of them, many many hundreds.

I currently...

Wesg,
A guard could be used around the template but that would restrict the movement of the router base. Quite often I need to move the base away from the tenon so I can measure and check for...

Thank you for that info.
I will see if I can find some of that Stabilant22... Looks Like I can get it pretty easily and not too far away.

Wesg,
I am not sure what you are referring to but there is no angle to the small end of the tenons, they are quite square actually. Also pretty straight.
The router stylus travels around the...

Scruffy,
I am really hoping you turned ON the pump and walked away........

Stephen, are these done yet? :D
