Thread: Bridgeport Mill - Worth Re-building?
28/06/2012 13:07:03

Hi Keith,

I took the table, saddle and knee from my 48" bridgeport to Brian Cady at Slideway Services - he reground all X and Y ways, added Turcite (PTFE type material) to both gibs and scraped it all to fir with gibs on maximum adjustment. Delighted with the results - like new, and less than the cost of an imported mill. This, in my opinion, is far, far batter that you would get from a import mill, and will last a lot longer.

Worth giving him a call and talking to him about it - make sure you tell him it its for model engineering / home workshop use. No connection, just a happy customer.

Good luck

Thread: Lathe & Mill
08/06/2012 12:22:01

Hi Smudge,

For that sort of budget, with a bit of patience (and if you have space) you could be looking at a Colchester Student / Harrison M300 lathe and a Bridgeport Mill. These would tackle pretty much everything you can throw at it, and as Terry mentioned, should you need to sell later on you would get your money back, maybe more.

Remember you can do small work on a big lathe / mill, but not the other way round.

Might be a problem getting it back to Jersey in your hand luggage though...

Good luck!

Thread: Surface grinding finish
15/05/2012 21:34:00

Hi Jim (Cahill),

You mentioned in an earlier post that you renovated the Eagle Surface grinder on lathes.co.uk - have looked at those pictures many times..!

I have recently acquired an Eagle surface grinder, and am at the stage of removing the spindle - could you let me know how you went about this on your machine? Considering the above information, I don't want to force anything, and I don't have any manuals or information to work from.

Great information on this thread - can't wait to see the results on my machine...!

Thanks,

James

Thread: Leaking Oil From Myford super7 Plus Big Bore
13/03/2012 21:45:00

Hi Bob,

Your problem may well be overfilling, but thought this may also help, as I had a similar problem after a rebuild.

Looking from the front of the gearbox, on the lower left is a large flat screwhead. If you remove this (when the gearbox is empty..!) you can access a fixing screw at the back of the gearbox that is in a direct line with the hole. This is one of the fixings that retains the gearbox to the bed. There should be a o ring between the gearbox casting and the bed around this fixing - was missing on mine, and oil would continuously weep.

Just a thought - perhaps see if the leak subsides after a while.

I'm no stranger to oil leaks either - I can tell when the oil has run out on my Series 2 Land Rover as the leaks stop...!

Hope you get it sorted.

Thread: Removing surface rust on machined surfaces
24/02/2012 23:30:36

Hi Martin,

No problem - sounds like you had a good find..!

Just in case it might save you some time or effort - mine is 3 phase also, and I was considering swapping the motor for a single phase unit on mine as it looked like a simple swap - however I found out that the original motor is a 6 pole (900 RPM) motor, so the normal 1400 RPM motors are too fast, so I went the phase converter route for mine.

Good luck!

Hi Martin,

Congratulations on getting your shaper - I have one, lovely machine.

If you need a manual for I have a PDF version - if would like a copy, send me a PM with your email address.

Thread: Bridgeport Wiring Diagram
23/02/2012 13:09:38

Hi Kwil,

I know this is an old thread, but I have been looking for a similar diagram as Dennis - could I trouble you for a copy of that wiring diagram if you still have it to hand?

Thanks,

James

Thread: Machine Manuals
09/06/2011 10:13:23
Hi All,
 
I have been thinking that a useful facility for Model Engineers would be an area where people can upload, share and download machinery manuals - more for the older machine tools, bridgeports and the like - I now have most of the ones I need, but knowing how much searching some of these took, it would be good to share these for others in the same position.
 
My question is would other people be interested in this, and also if there are copyright reasons why this would not be possible?
 
Maybe as an area on this site, or set up on a seperate website?
 
What are your thoughts?
 
James

Thread: Myford 7 Motor

Hi,
 
Thanks for your comments - sounds like the key is a decent british motor as much as anything else.
 
I guess you get what you pay for....

Thread: Myford ML7 travelling steady 'fingers' size
18/05/2011 12:27:22
Hi Martin,
 
On the subject of paint, I have used the people below for the paint on my Myford 7 rebuild - this is machinery enamel, and I have brush painted and sprayed it, and the finish is superb. Have yet to see how well it lasts, but so far so good.
 
They do a range of old machinery colours, including Myford Grey and Green

Thread: Myford 7 Motor
17/05/2011 14:44:48
Hi All,
 
I have read many posts about the virtues of 3 phase motors with inverters, but have a question regarding single phase motors.
 
Having rebuilt my Super 7B, I am at the stage of attaching the motor and drive assembly. The motor that was driving my lathe previously was as an old 1/2 hp single phase motor (no brand name) which was obviously not the original motor, as is has been attached to the mounting plate previously with a rather crude adaptor plate.

The motor is a rigid mount style motor, not a resilient mount type, as recommended by Myford - the motor is worn, but quite useable.
 
My question is, would there be any real advantage in sourcing a new resilient mount single phase motor - would this make any appreciable difference? Has anyone had a similar experience?
 
Thanks,
 
James
 
Thread: New I/C diesel project - ETA15d-x2
09/05/2011 21:01:32
Hi Ramon,
 
I always read your posts with interest, although I'm afraid i'm not always very good at actually posting a reply... Its nice to see other peoples approaches / setups - even if not relevant to a particular project at that time, you can often apply an aspect of it or may be useful at a later stage.
 
Like you I don't belong to any clubs, both for reasons that my time is limited and also my interests lean toward IC engines and road steam, rather than locomotives, so seeing other peoples projects progress is nice.
 
Keep them coming!

Thread: Dovetails
21/04/2011 21:15:33
Hi Ramon,
 
Thanks for that - I think some experimenting is called for!
 
My mill is a larger older machine, so rigidity is not a problem, but have some backlash in the feedscrews to work with.
 
I will get some bits from the scrap box and and have a play and compare finishing cut methods. Would this just apply to dovetals, or 'normal' milling as well?
 
Also, just to let you know, your diesel engines posted here recently have inspired me to get started on my first IC engine - have chosen a Sparey 5cc diesel!
 
Thanks,

Hi John
 
I have an Elliot 10M - not a huge machine, but big enough for me - doesn't take up too much shape in the workshop. As I say, still learning, but the fact you can use HSS tools to get a good finish is ideal.
 
One thing I want to get to grips with is keyway cutting, and have also an old ME article showing a worm and wheel setup on the tool post to allow you to cut radius surfaces - i.e. chimney bases, etc.
 
What do you have?
 
James
21/04/2011 09:20:43
Hi Ramon,
 
I was interested to read that you suggest a fine finishing cut by climb milling to get a better finish - or have I misunderstood? I have always avoided climb milling where possible...
 
I'm with John on the shaper - still learning on my shaper, but very versatile, and a great finish. Nice to watch too!

Thread: Paint Stripper
12/04/2011 16:47:46
Hi All,

Thought I would post this in case it was of use to anyone.

I am restoring a couple of machines at present, a part of which is removing the old paint, and I have been using Nitromors paint stripper - does a very good job. When my last tin of stripper ran out I went to get a replacement, but I could only get a new 'improved, double strength' formula. Well, I can only imagine this was described as 'improved' as it doesn't spoil the paintwork you apply it to... Not impressed.

After some research, it turns out that the old style Dichloromethane based stripper was banned on 1st December 2010, and once stocks of the original formula paint strippers are gone they will not be replaced - they are only producing more environmentally friendly products now, which from my experience doesn't touch machinery paint.

I found www.restexpress.co.uk still have some old formula stripper left and I have ordered some - if anyone is planning a similar project, might be worth doing the same.

No connection to the above company, etc.

Hope it helps somebody...

James

Hi Ramon,
 
I must say they look great - look forward to seeing the completed engines!
 
How do you get that lovely satin finish on the crankcases - are these sandblasted?

Thread: Complete Beginner
27/03/2011 21:57:40
Hi Ryan,
 
Might be worth having a look at Tubal Cains book ' Simple Model Steam Engines' - written from a complete beginners viewpoint, will guide you through all operations - some machining, some boiler work, some sheet metal, and assumes a limited equipment.
 
The book provides all drawings, and the engines are made from stock materials - no castings. As well as getting some experience, you get a finished model quickly to spur you on.
 
I found it excellent when I was starting, and am now starting to build another with my son for him to learn on.
 
Good luck!

Hi Tony,
 
I've not tried myself, but I have been told you can source spares from the link below - they offer rebuilt Bridgeports...
