Found the issue.

I finally got around to looking at the jamming column.

After taking the motor, the head, column and column base apart I found the issue - the vertical lead screw was bend!!

Simple fix, put the lead screw in the base bearing casting and bent it back!!! All is well and mill is great.

Hi Mike,

I can check that by wiring to 240 and checking it operates OK. Will post results.

Thanks

Jeff

Hi,

I have a single phase Myford Super 7, I did not get a cabinet with it, so I have just bought an industrial style cabinet for it.

I think the cabinet is wired for 3 phase. See pics below:

The loose switch in the pictures is the coolant switch.

I have some specific questions:

1, Can anybody confirm this is a panel for a 3 phase motor?

2, Can anybody confirm a rewiring scheme to wire up my single phase motor?

3, The panel has high and low speed, that I believe would require special 2 speed motor, single or 3 phase. Is that true?

4, Are my options limited to ? :

4a, Rewire for single phase

4b, Install an inverter. If so am I correct in thinking I need a three phase motor, as well as an inverter?

4C Any other options?

Thanks in advance

Jeff.

Hi,

Any recomendations for 3 axis DRO for a Tom Senior Type E?

Price range - well not super ebay cheap.

That's an idea, I will have a gander. But it would need to be a big dint to stop it so quickly and it does not get jammed.

But that worth a go as it has just been transported by me.

Hi Eric,

Yes I tried that. I found that it freely falls when the wheel is rapidly wound up, then pushing to and fro, as you suggested, gives me another 3 mm or so. And there it stays!

I just noticed the guideway adjustment screws at the base. I will give these a bit of slackening, but as mentioned I cant see the keyway guide coming through the base, so I'm struggling to see how its held.

Thanks

Jeff

Hi Simon,

Yep tried that. I clearly have oil coming through the lower end.

Hi,

I have just got a Tom senior Type E and cant get the column to lower. I have:

Loosened the two hex head cap heads on the clamp at the base.

The keyway guide is engaged.

I can freely lift the column up, but when winding to lower it, it only drops so the main column is about 6mm past the bore of the bottom bracket and stops.

From below I can see the keyway coming through, and it seems clear of any clashes at the keyway of the bench mounting?

Any ideas?

Regards

Jeff

Hi All,

Hope this post is in the right area.

Im looking for a manual that will cover servicing of an E type mill. Particularly interested in lubrication and adjustment of quill.

Many thanks
