|Thread: Moving a Myford VMC advice needed thanks!|
If you are renting a Transit, can you you not rent a Luton with a tail lift?
Normally can lift a ton plus which should cope with a VMC intact and on the ground I used some short offcut lengths of scaffolding under base to manouver to position.
|Thread: Taking Leave|
Whilst fully understanding the priorities of life, I hope this will be a scaling down of forum activities rather than a complete disconnect.
As a fellow M300 and Bridgeport mill owner, it is good to know that there is someone out there with more knowledge than myself regarding these machines should a query arise.
Unfortunately the internet is a double edged sword, allowing people to easily connect but also allowing people to easily insult. My approach is just to develop a thicker skin.
But I hope as your life readjusts we will see you at some time back on the forum with your knowledge.
|Thread: Harrison 300 Swarf Shield|
I have just noticed you said that you drilled and tapped the holes.
I agree with Clive that the sight glass was probably a push fit, possibly with an "O" ring.
Out of idle curiosity. Just going back to the swarf shield, which in your pictures is screwed to the headstock. Did those tapped holes exist or did you drill and tap. My headstock has no tapped holes.
Andrew has prempted me regarding the use of the mounting pads.
As for the oil sight glass I don't think it is possible to clean it. They are made of plastic and the oil ends up permanently staining and deteriorating the plastic. Mine is almost totally opaque. Impossible to use it to check oil level.
With out wishing to side track the thread.
Your pictures high light something I have never noticed before.
The question I would like to ask, is do you have on the back wall of your bed a plain area with tapped holes for mounting accessories?
|Thread: Cigarette Papers|
I always used to scrounge the tins and still use them 40 years on.
|Thread: Welding precautions|
|Thread: Press Button Oilers?|
Thanks for link.
Without wishing to side track the thread.
|Thread: Parting off|
I have to agree with the comment about the Chronos "T" shaped parting off blade.
The Chronos "T" shaped blades are extremely rigid. Ensuring they are set square and at centre height and I have parted off 60mm diameter stock like a knife through butter. Just touch up the front face with a diamond hone to resharpen and the contoured top surface just curls the swarf clear.
|Thread: Belt Up|
Both my belt sanders are older and British. Both have crowned pulleys and tracking.
Maybe I am not keeping abreast with modern engineering practice.
If you look at any belt sander / linisher you will see a crowned pulley. It can give you an idea of scale and shape.
|Thread: An Easter Tale of Cordless Batteries.|
A good few years ago Screwfix had a special offer of Titan 18volt cordless drill with a charger and TWO batteries in a case at a very competitive price. The drills were probably old stock, end of line clearance but the price was so good and as I had a discount voucher as well, I bought two sets. So I had two drills with two chargers and four batteries.
Four batteries dying at the same time? Bit unusual!
So with Easter lockdown I've got time to investigate.
Measured battery voltages, They were flat as anticipated. Each showing between 1.5v and 3v.
Measured resistance on the battery between minus and the “T” (Thermistor) terminal and all four batteries show 11.5Kohm. Again, can’t believe all four batteries dying with exactly the same fault at the same time
Question: Can anybody tell me why this should happen? What is going on?
Suggestion: If you have a dead cordless battery (minimum 12 volt) try this and see if you get the same results!
|Thread: Bottled Gas Suppliers|
I have used Hobbyweld for several years now and haven't had any problems. There seems to be a good spread of agents around the country.
|Thread: Yet another 'which mill shall I buy'|
XD 351 - " So how many of you Bridgie owners use all the features ? "
How many of us have tooling and materials squirreled away with " might come in useful one day."
I notice there is a thread currently running with someone resorting to putting jack screws under his column to be able to tram it fore and aft. Maybe the nodding head "once in a blue moon" moment has arrived
I would have to agree with the Bridgeport camp. My Bridgeport replaced a Myford VMC on a base in a standard single garage. Slightly bigger but fitted in the same space just had to allow a bit more room for table travel. Slightly taller but not by much.
But the biggest advantage was the available space under the quill (max 480mm). The ability to be able to have a largish piece of work on the table and be able to drop the table to facilitate changing large or long tools without losing alignment just makes me smile every time I do it!
|Thread: Bridgeport Help|
Having recently acquired a Bridgeport. I have discovered that the feed reverse knob assembly has been sheared off at some time. The assembly is attached to the reverse clutch rod by what appears to be 8- 32 UNC thread measuring at 5/32 and this has sheared off inside the reverse clutch rod, so try as I might I cannot remove the remains.
I have obtained new spares but the clutch rod is pinned to another rod in the head to which I would need to access to replace.
I have copies of the Bridge port manual parts list but this just shows a whole page of disembodied parts with no indication of interconnection. There is no easy direct access to the parts to view and I know that in there, is a whole load of worm gears, springs etc. and I am not particularly keen to go in and start dismantling and have a whole load of bits explode on to the floor!
Anyone had any previous experience? - or any pointers to information?

|Thread: Hello from West London|
I have been following this site for a while but thought it is now time to introduce myself.
Been pottering about in home workshops ever since childhood. Father was an engineer, so if I wanted to make something or if my bike, for instance, had a puncture or needed fixing, he would show me what to do and thereafter if it happened again he would say "you know what to do - fix it". Same when I acquired my first cars etc.
Always liked fixing and making things. Had veteran and vintage cars and motor cycle flat tankers. Had to make your own spares!
From starting off with a Myford, currently have a Harrison M300 and a recently acquired Bridgeport squeezed into the garage.
Would like to chat to anybody who has experience of Bridgeport head internals, particularly access to the fine feed reverse knob assembly and the reverse clutch rod linkage.
