Thread: Unnecessary waste of paper
28/11/2018 23:26:56

You will find that most of this paper is due to EU rules and they harp on about saving the environment!

Thread: Schmidt Couplings
28/11/2018 22:39:59

Does anyone have any drawings for a Schmidt coupling or where I can buy one about 25mm diameter?

Thread: Anyone bought a new Myford

8k to 9k will buy you a very good secondhand Colchester Lathe and a Bridgeport Mill!

Hi Andy

As these don't have to be too accurate, I believe they where made with a form drill. Have you got enough room in the hub to fit a straight stepped spacer?

Thread: High tensile steel

It machines fine with tip tools but I'm not sure if it is suitable for exhaust valves.

Thread: Cutting a large round hole
21/11/2018 21:17:02

You need a longer tool.

I have Jason but it not big enough

Try lapping them in.

Thread: Remove play in internal square thread

You could white metal the nut, this will remove the back lash and will last long enough to make a new nut.

Thread: It's a thread Jim, but...

Use Rocol cutting oil and this helps a lot.

Thread: The new talking Mercedes
17/11/2018 10:04:55

I had a Honda CRV that had done 250k and failed it's MOT on emissions but was still totally reliable and rust free.

Mercedes are absolute junk! Fortunately for me I profit from their poor quality. Heater plugs regularly cease and then snap off! Timing chain sprockets are made from cheap sintered crap and fall apart at about 50k stuffing the engine!

Making steel sprockets and removing heater plugs should pay for my holidays for the foreseeable future!

Thread: Lead Bearing Solder is Banned
14/11/2018 09:55:18

I make my own using old tankards and lead pipes.

Thread: press fit sizes
12/11/2018 18:37:16

As a rough guide you need the hole .001" per inch undersize. So you need to make the holes .0005" under the size of the silver steel. So measure the silver steel first then set your reamer to cut as above. I would make a test hole first.

Thread: An alternative to parting-off
04/11/2018 19:44:44

You make one! I own several lathes and one of them is a Galileo 330 x 2000 with hydraulic drive.

Never understood why people have problems with parting off. Now we have insert parting tools it's a doddle, as they are made for power feed parting off. I usually set the lathe speed to about 500rpm to 800rpm and a medium speed feed and let it go.

I have happily parted off 10" round bar with no problems.

Where does one obtain a parting off tool with a 5" projection? And what lathe runs it?

Not everybody has power cross feed. CNC apart, how does conventional parting off account for the progressive reduction in surface speed of the cut?
