|Thread: magic 127 TOOTH ?|
I use a combination of a 127T and 50T gear on a Myford ML7 to cut metric threads as this gives a ratio of 2.54 to 1.
The setup has to be run without the gear guard though!
|Thread: electric paint sprayers|
My experience of this type of spray gun is that they are adequate, bordering on suitable for coating sheds and fences with preservative, but you will be very very lucky to get even a reasonable paint finish. Some years ago a friend of mine attempted to spray a white car with a gun of this type. The result was a car that looked like it had been coated in rice pudding !!
|Thread: Is it bad practice to lock my Myford lathe using the slow speed lever|
The advice from an original Myford manual is as follows:
"When removing a chuck (or faceplate), do not 'yank' the chuck off with the headstock locked with the back-gear,, but set the headstock for normal back-gear drive, and after placing a piece of hardwood on the lathe bed, pull the spindle round by means of the belt so that one jaw of the chuck or slot in the faceplate strikes the wood sharply. The most obstinate chuck is released in this way, and a great deal of the load is taken from the back-gear teeth".
Myford ML7 Notes on Operation, Installation and Maintenance (No 720G , M. 3M /11/64)
A method I do not recommend is that if you have a 3 phase inverter drive that is to set a short braking time and run a 9" faceplate (anything else heavy for that matter). The spindle stops very quickly but the faceplate doesn't which necessitates some nifty footwork!! Needless to say the inverter is now set to coast to a stop. Minor damage and no injury but lesson learnt.
|Thread: Belt sander recommendations|
Have a look on Youtube for DIY belt sanders. There are some very resourceful people out there.
|Thread: water supply|
If I remember correctly, during the water shortage of 1976 the UK government issued the advice to "Save water and shower with a friend" !
|Thread: Electricity Supply|
The government has announced that all homes in the UK will not be heated by natural gas by the middle of the century. Is the alternative electricity? . Where will it all come from?
To quote Private Fraser, "We're all doomed".
|Thread: ML7 compound slide setup|
To quote the official Myford ML7 maual,, "Careful attention should be given to the screw adjustment to ensure an even pressure of the gib strip.When stripping the compound slides for thorough cleaning and lubrication re-adjust the slides without feed screws and screw support brackets, testing the slides by hand motion, re-assembling the feedscrew units as the last operation" (ML7 manual M.3M/11/64).
The manual also recommends an oil of 30 viscosity on cross and compoud slide ways although I tend to use slideway oil on the majority of sliding surfaces and moly grease on feedscrews.
When you re-fit the feedscrew and bracket keep the 2 bracket screws slightly loose and wind the slide in to the end stop before tightening the bracket screws to ensure best alignment.
|Thread: Single to 3 phase invertor and smart meters|
I cannot listen to my little LW/MW/FM transistor radio in one corner of the living room since having a smart meter fitted. Lots of interference from the meter on the other side of the wall......but that's another can of worms!
|Thread: Atlas shaper|
A very desirable piece of kit in my opinion, definitely not for scrapping!
|Thread: Telephone / Internet Scams|
Just say "Cut the cr*p, let's get to the reason for your call. Would you like my bank details now?" It appears to confuse them!
|Thread: The demise of the High Street|
Saw a busker in Solihull today with a sign "Cash or swipe". You can see where it's all going.
With the rise of internet shopping and demise of the high street, how long will internet prices and delivery costs stay low?
|Thread: Has this Adept shaper been repaired?|
Can't see any sign of repair in the photo's, but the castings on mine are also a little rough. Doesn't detract from the fine finish that can be achieved with these little machines though. Paid less than £100 for mine, but that was a while ago. Keep meaning to come up with some means to enable self-act as the operation is a 2 handed job otherwise. The toolpost shown is a special to enable internal keyway cutting, but a standard toolpost is easy enough to make.
|Thread: Myford Super 7 quick change gearbox fitting|
What you say Michael makes sense, I should have realised this. My excuse is brain fade from late night posting following daughter's 30th birthday celebrations!
According to a drawing I've found on thinternet, using the existing left hand tapped hole as reference, the first tapped hole for gearbox is 1.88 inches to the right, and the second 3.748 inches from the reference.
They seem to be very odd dimensions. Could somebody confirm please?
|Thread: Myford ML7 - Direct or Back Gear|
You may also be aware that using backgear not only reduces speed but also increases torque.
|Thread: JB cutting tools .com|
Bought some tools from the lady at the spring Stafford Classic Bike Show and she was very helpful, even threw in a spare tip for the parting tool.
Asked for a 55 deg internal thread cutting tip at the last Bristol show but she did not have one on the stand.
Promised to have one for the Midlands show and lo and behold, it was there for me yesterday.
No connection, just a satisfied customer.
|Thread: One way to defeat Mr.Sod|
A boss I worked for many years ago said that if you drop a part and can't see where it went, take a similar part and drop it from the same position but watch where it goes. There are even odds that it will go somewhere near the original part....or so he reckoned!
|Thread: Selecting and installing steel mesh for a concrete pour|
If you are planning to fasten your machinery to the concrete floor, have due regard to where the reinforcement is situated in relation to the fixing points. Drilling reinforced concrete and hitting the steel reinforcement can be a real P.I.T.A. !
For raising the mesh off the hardcore, maybe something like these:
