Any good source for Colchester 6500 half nut?

$
0
0
I'm looking for the half nut assembly for a Colchester 6535 15x48 lathe. I have an email in to Clausing, but I'm expecting the number to be breathtaking. Anyone have an other good ideas I should follow up? I've been watching ebay, but there's not a lot of 6500 series stuff on there. I've read threads on fixing them up, but my lathe came without one (I assume PO removed to replace and never got around to it.)

It's #26 in the diagram. If I have to turn my own, I can imagine how to do it (and have another 12" swing lathe that should be able to handle it). But it looks like some work to get it turned, cut out of the whole cylinder, and then locate that pin properly.

Getting a 5-c collet sleeve out of a mori seiki 850 6mt spindle.

$

Hi there,
I have a Mori 850 equipped with an old manual Royal 5C collet closer. The 6MT spindle sleeve that takes the 5C collets is stuck in the spindle.
I have seen photos of pairs of wedges which you squeeze together with a big C clamp to pry the thing out. The wedges are C-shaped with a straight back.
In the past I have used a single wedge with a hammer on other machines (because it was available). I like the former method better.
Question is, can I buy those wedges someplace, or do I have to make them myself? If I have to make em, does anyone have a drawing?
Thanks an awful lot for any help you may have to impart.
Thanks,
Walter

Weiler Matador Headstock assembly!!!! HELP PLEASE!!!!

$

To anyone out there that can possibly clear up a mystery in regards
to the 80X3 O-Ring on the spindle assembly.

I can see the O-ring in the Weiler drawing, but cannot understand its function? Can someone please explain to me the function of this O-ring and its importance?

The pulley which is pinned to a keyway also has about 3mm sideways movement? It is not loose, but the assembly which it pins onto underneath has sideways play. The below unit has gears and a spline which engages and disengages.

Thank you

Need someone that help me with dimensions of missing drawer bar for lever action collet closer.

I am not sure if there is only one component missing or more, but I do know that the drawer bar is missing. If someone out there could please take some accurate and detailed dimensions of their collet draw tube, I would greatly appreciated.

I would like to make one for my machine, but have no information. I would also like a picture of the collet holder if possible. I would like to make one for my set of 5C collets.

Thank you

VFD issues with SAG12

$
0
0
I am running a 3hp SAG12 with a 4hp VFD without a brake resistor and frequently have VFD shutdown when activating the transmission clutches to change speed or direction. It happens every time I reverse direction without waiting for the spindle to stop and otherwise about 1 time in 10. The error code indicates this is a transient overload issue and was wondering if anyone else had run into this problem and had a solution. It doesn't prevent me from using the lathe but is a nuisance frequently resetting the VFD.

Any suggestions? Would a rotary converter using an idler motor be a better solution for the SAG12?

Thanks, Tom

who has a 'metric' Weiler Matador VS-1????? Need charts urgently

$

I have been going in circles for weeks now looking for a Feed chart for the Matador VS-1. The charts I have in the german manual are not the same as mine.

My Matador utilizes 25t-120t-80t on a 6mm lead shaft. The manual shows Feed charts utilizing 21t-120t-84t on a 6mm leadscrew.

I can only assume this is the difference between the Metric VS-1 & VS-2 models?????
Well my machine that I am currently restoring is missing both the thread charts which sit on the feed box and gear change cover. My feed chart is also damaged.

So I am asking for HELP here, I need someone with the same machine to photograph these charts. I can then make some for my own machine.

FS - Schaublin SV90 headstock & tailstock, W20 collets - antiques for the collector

$

I have Schaublin SV90 headstock and tailstock for sale. Link to SV90 info. These came on an SV-102 bed, but were too low to use with the Habegger 102 compound I have, so I made 12-mm riser blocks. I was setting it up for the kids as a training lathe (before I turn them loose on my Monarch 10EE!), but never got around to finishing the project.

The headstock is plain bearing, W20 taper. The taper and threads are in good condition. The collet drawbar thrust bearing is not original but works. The indexer pin it missing.

The tailstock is 2-degree taper. The taper is in good condition.

The riser blocks fit nicely and but have not been scraped into final alignment. I have both the original and extended "T-bolts" for locking to the bed.

I am asking $75 each or $130 for the pair, plus shipping. I'll take PayPal. The 102 bed is also available, but may not be economical to ship. I also have 15 W20 collets, 1/16"-5/8", half of which are like new and half of which are very good. $16 each or $220 for all, plus shipping.

A couple years ago a made a schematic of our new (used, but just purchased) SAG 12 and have been meaning to post a copy of it for anyone who might think it useful. FYI - I'm an electronics technician by trade and I play around at machining.

Multifix/Multiquick type Aa tool post

$
0
0
I just acquired a multiquick tool post( another version of multifix) model Aa from SPI. I noticed a number of things and would like to know if there are parts missing

1 there was no T bolt included to attach it to cross slide-it may be because it is lathe specific

2 there was no arrow indicator at the top to indicate one of the 40 divisions on the scale

3 when the unit is rotated it rotates freely and does not ratchet from one degree to another. The reason I ask this is because of this video I saw on you tube
https://www.youtube.com/watch?v=39rALHrEcLo

4 there were no instructions which may have answered these questions

Appreciate any help




Thank You

German members- What exactly is the deal with GDW and Weiler ?

I checked out a Graziano sag210

Little trip report:

I saw the machine in a small ads advertisement and the price was very interesting for the description. Asking price was 4100 E for the original paint little use machine originally from a model shop. Including the original manual, a 3 jaw chuck, a large faceplate and the original turning tip plate (dont know the correct term) + some Multifixes. A phone call confiirmed the original paint.
Now, such machine with original paint still perfect directly under the chuck seems exceptional. The pictures in the ad were pretty much useless for condition. Way too grainy.
I looked at the machine on my way home, which would have been only 30km detour, but on a Friday afternoon near Cologne, this cost me an hour in the traffic jam from hell just to get there.

When I finally got there it turned out what I had already suspected: the machine was repainted. Rather nicely done and not by the seller, but rather obvious. Also a shade too dark and inside the bed in red (???).

The machine was not abused, but had run quite a bit. The fragile aluminum plates this machine has so much of, were not horrible, but not so good either.
Not much wear on ways, but just noticable.
It was the "n" machine, not "nr" or "n3r".

I was scared of the electromagnetic clutches, as I do not need another project. I count 8 such clutches, 6 in the headstock and 2 for the feeds. The seller said he replaced one on another Graziano and it was easy and cheap. I remained sceptical.

The operation side is decidedly ungermanic. The crosslide feed lever will feed in when pushed in, but will not feed out when pulled out. Pulling out activates the longitudenal feed. Very unexpected.
The seller also has a Lacfer lathe (very impressive) and had the same problem, that operating both lathes makes them unintuitive, because they are so different.

As it is I did not have to "rescue" another machine, but if the machine would have been as perfect as hoped, I would have had no choice. These machines are nice and a bit artsy. Should have featured in Jacques Tati's "Mon Oncle".

I told the seller the machine was a bit too expensive for its condition (not really true, but true for my situation), to which he graciously replied that I did not have to buy. True statement.

At least I've seen a sag210 in the flesh now.

Köping S8 - 1948 Vintage

$

Hi all.

I just got my "new" S8 home this weekend, after a 800km roundtrip.
The lathe shows remarkable little wear, the ways are like new, all lead screws are in mint condition, only light surface rust some places.

The previous owner bought the lathe in the mid 70's and has never used it.
Before this, the late was lightly used as a tool room lathe.

It came with two three jaw chucks, one 4 jaw scroll chuck and a regular four jaw, backing plate, two live centers (Mk-5), dead center (Mk-6), two steady rests and one following rest.
Some of the chucks are a bit rusty, most likely having been stored on the floor. They do not show any wear though.

I was under the impression that the Köping lathes came with a L-2 spindle nose, but it seems like this lathe does not.
Probable the early Köping lathes used a different spindle nose..

If anyone can help me identify what type of spindle nose this lathe has, it would be greatly appreciated..
I'll post a picture below of a chuck backing plate showing the type....
It has both an internal and external thread, but there does not seem to be any taper any where?

Graziano SAG 14 Manual, New owner advice?

$
0

Hello,

My first real machine will be coming home in a week or so, would anyone have a scanned or PDF manual for a 50s ish SAG 14? I very excited about the lathe and have checked out it's history etc on lathes.UK. I hope to get a 5c nose or collect adaptor for it. It comes with 3 and 4 jaw chucks, both 10" which need cleaning up, and that's about it. I'd love to get a steady rest for it too, are such things ever on eBay? I see a local 7.5 HP rotary phase converter, which I think so be more than I need, but any advice is welcome. It's going in the garage, I'm an IT guy that likes to play with machines, in my spare time.

Thanks
Pete

Cadillac 1428 - Wiring

I have a lathe that I just powered up. Seems there are a few problems with it electrically speaking. I can't get the hi switch position to run nor the motor to reverse. After mucking around in the electrical cabinet I was able to make both work by manually pressing the button on the contactors. I've attached a picture of the contactors and what I believe to be the function of each by following the wires in from the outlet. I need to do some more testing to see if it's the switches or the coils which have failed. I'll do that in a bit... however, does anyone know if the contactors are serviceable? I am just thinking that it will be a real pain if I have to locate another contactor with the same footprint and all (or maybe it won't be).

Also, the coolant switch has been disabled. The leads attached to the contacts from the switch just hang down and connect to nothing. Anyone have a clue where these should go? I don't see anything obvious. My hunch is that it goes to the contactor labeled '???'. The problem is that the contactor is tucked back in there so it's hard to see anything. Anyone have a wiring diagram for a similar machine (or the same)?

Whacheon WL-435 Brake Master Cylinder Automotive Equivalent

In the process of overhauling the brake on my Whacheon WL-435, I replaced the master cylinder. A clutch master cylinder from a 1979-1980 Mazda 626 is a perfect replacement (same bore, same port, same mounting bolts).
Centric part number: 136.45100
Interchange Part Number: 39410
This probably fits the Mori Seiki MS too.
Hope this helps somebody out.

Schaublin 102N-CF or 102MI-CF ?

$
0
0
I wanted to get the pros can cons of having an integrated motor as in the 102MI-CF or the separate motor as in the 102N-CF for a Schaublin 102.

It seems to me that the integrated motor would not be as micro precise as the N model due to macro vibrations caused by the motor being integrated into the headstock of the lathe.

If you were in the market for a Schaublin 102, which model would you buy?

This machine would be used for turning things that are from 5 - 10mm. Would a W20 collet version be more suitable or the W25? W25s seem to be much more rare and might be overkill for the size objects required.


Thank you,

Spindle on during tool change parameter

$

I'm setting up a Mori SL-25 for a rather large run of parts and waiting for the spindle to ramp up and down for every tool change is killing my cycle time.

It's the MF-T6 control, which, with a little research, I've found is basically a 16T Fanuc control. I'm looking for the parameter to change so the spindle doesn't stop for every tool change. I've looked everywhere else and can't seem to find any information on this.

Any help is appreciated.
