The Sajo mill is here
Trion:
Thanks guys, I'll look into clamping the head of the vise when I get myself a clamping kit. I'm lacking tooling and funds at the moment.
DMION: I had forgotten all about the ram adjustment :doh:
But yesterday I gave it a go
Then I figured I'd loosen the vise and position it a bit further onto the table, but when looseining one of my homemade t-studs it broke off. Looking at the broken zone, I can see see something looking like a big grain growth in the HAZ of the weld. Must have weakened the bolt quite a lot, but I'm still amazed that it broke. Could it be hydrogen enrichment from the snow hardening? ::)
Well, here the vise is temporarily fixed and the head adjusted to a usable position

On another note, I said I'd post a picture when the Nissan is running, and guess what happened yesterday? :ddb: :ddb:

Hi Trion,
I've not been here for a while and only just found your thread.... That's a nice huge mill and a vice to compliment it!!! :jaw:
If you have any endmills/slot drills I'd make a few new T nuts first job :thumbup: scary having ones that snap :bugeye:
But I also just had to say.... Nice motor :headbang: SX? I'm hoping there's a filter to protect that huge shiny snail somewhere too? :)
Ralph.
Trion:
Thanks! Yeah, s14 as you probably have noticed. I have a 4" intake pipe and HKS mushroom filter, but for the first startup after a rebuild, I like to double check that things are working. After snapping 2 rockers, bashing two hks cams and bending 4 valves I have learned not to trust the SR... :hammer:
There is a 4000 picture build thread about the car on the members area of the norwegian Silvia forum. Good for killing a few hours, if you speak norwegian (and have paid the membership fee) :lol:

It's been a while since I have posted here, haven't done much either. Most of my time is being spent driving the Nissan, and reading for my exams.
But I have managed to sneak in a few hours, where I have changed the oil of the vertical spindle gearbox :)
The spindle is running nice and smooth, and all gears work fine. With one exception at about 800rpm, which is making a slight grinding noise :scratch:
Here's the table feed gearbox being drained, and new hydraulic oil is soon to be poured into it :)
That's about all there is to report. I have bought quite a few new Mitutoyo measuring tools, and finally got around to order a ER32 collet set for the mill. Beware, there might be a bit of gloating in the next post ::)
Trion:
I sai'd there was going to be gloating :D
You are looking at a MT2 live center with exchangable tips, MT2 collet chuck for the tailstock, MT3 collet chuck for the spindle, 25mm shank collet chuck for future QCTP and ofcourse ISO40 collet chuck for the mill. I also bought a few spanners and ofcourse a complete set of ER32 collets :D
I first tested the poor mans collet chuck on a valve I had tried to turn in the 3-jaw, with loads of scatter.
It turned out like this, valve-grinder ground valve in front and turned valve in the rear
Here's the tailstock collet chuck for the times i need to chuck a reamer or a large drill :)
I only have a drawbar for the vertical spindle for now, so I tried the collet chuck there
But being a newb, I got into truble right away. I put the collet in the chuck and put the nut on, but when tightening it, it stopped far from the edge. So I took it apart and noticed some slight damage to my 10mm collet :bang:
So I figured, something must have been wrong. When I looked into the collet nut, I found the bugger. As you can see, there is an edge which is very out of round
So I put it on the lathe so measure the runout of this edge, but it was more than the 0,8mm of travel my new Mitutoyo DTI (gloat gloat) had to offer..
At first I was thinking, thats why they were so damned cheap. Should have spent the money on the real deal instead :bang:
But then I started looking at the other collet nuts, and strangely they had all the same runout. And then I realized it. One is supposed to put the collet into the nut by slightly pressing it in by hand, and the put the nut on the chuck.. :bang: :bang:
After that, I was ready to make the first swarf :ddb: :ddb: :ddb:
Yup, thats some milled aluminum. I took about 0,5mm cuts back and forth, climb milling definetely gave the best result
Some of you might remember that my homemade t-slot studs broke a while ago. Well, here's yesterdays setup. The milling cutter is rotating away from the car, I'm not crazy :lol:
On another note, i ran the vertical spindle again, and tried to chang the rotational direction. In what seems to be the right direction for drilling and such, there is a lot of noise coming from both the head and the gearbox. The noise increases with rpm and sounds like something hammering in there. I might be looking at a head+transmission overhaul this summer :dremel:
