The Sajo mill is here
Bernd:
Nice save on that electrical box.
That short sounds like a wiring problem. Although I would assume that the "E"-stop would drop out a relay in the control box. Do you have a wiring diagram that came with the machine? Maybe we can figure it out.

Trion:
Thanks fellas :)
Yes, there is a wiring diagram in the first pages of this thread, although not so reader friendly. And I am pretty sure Bernd is right that there is a wiring problem, because the fuses only blow when pushing the e-stop while the machine is running. So it's taking current somewhere it shouldn't be, while when the machine isn't running there is no electricity to go that route..
Well, I said there might be a tool gloat this weekend..
I found out that a friend of mine had no less than three monstrous machining vises he had got from a shop upgrading to newer tools. When I got there, I really understood the meaning of monstrous. The biggest one was over 50cm long and a struggle to lift with two men! Besides, all of them were hydraulic! So we talked a bit, and he explained that he only needed one, to use as "regular" bench vise. So I could pick the one I wanted and have it for free :D :D
I took the smallest one, because the bigger ones would have made Y-direction travel absent on my, in perspective, quite tiny mill!!
Pictures, pictures.. I know ::)
There are no names on it, only thing are these numbers stamped in the casting: 2262 994
This vise already protrudes a bit into Y-direction travel because of it sticking over the table..
Width of the jaws are 160mm, not extreme but ok. One jaw is missing, so I'll need to come up with something there..
The vise can be opened up to 30cm, by moving the fixation bolt seen to the right :thumbup:
So what's the right thing to do, when you have got new stuff? That's right, pull it apart and try to understand how it works!
Yesterday I had all evening, and nothing else to play with, so I decided it would be a good idea to clean it up a bit
One thing led to another, all of a suddden the vise had been treated with an angle grinder and a wire wheel, then with a flapdisc, washed with ethanol, then some tougher stuff and finally masked for paint
The question was if I was going to paint it in durable gray epoxy primer or the cheaper sajo-green one component paint.. That led me to check out the test piece which had been standing in old coolant and oil for a few weeks now. A quick scratch test with a knife revealed that the paint was a bit softer where it had been left in coolant. But since it is a vise, and probably is going to get quite a few scratches, I decided to go for the cheap paint anyways.
Some minutes later it looked like this :beer:
Today it's getting another layer of paint. Then I'm going to let it dry for a couple of days. After all, there are only a few degrees celsius inside the workshop. Cant wait to get it assembled though :D :D

Just a little bit of - literally - orthogonal thinking. Although its usual / traditional to mount the vice in lne with the Y axis, you could mount it in line with the X axis and the operating handle off to, say, the left hand of the table?
