Thread: Tool identification
17/10/2021 15:23:06

Hi Colin don't try and put a radius on the cutters with the chip breaker as they will rub and you can't get center height correct. Just grind off the end of the tool and a rub with a sharpening stone on the cutting edge. I use the corner of a grinding wheel along the groove and sometimes use a small diamiter grinding point in a dremmel to smooth it out. Don't use on brass, bronze, cast iron or similar materials as they will grab and chatter.

Hi Colin the groove is on the top of the tool on all three tools. I use this style on softer materials aluminium or EN1A steel for instance to get a good finnish and the third style I would use that as a roughing out tool for the same as the top groove acts as a chip breaker as well.

Thread: SKY abandoning their satellite customers
11/10/2021 18:48:05

When my in-laws had sky installed the installer drilled through the wall and clipped the satelite twin cable around two rooms walls on the top of the skirting board and thorough the door upright woodwork. I fitted a conduit through the floor of the front room and part of the middle room the where the sky box was installed. I pulled out the cable and re-routed it through the conduit and had to cut off 10 meters of spare cable. If I have a fibre optic cable to my house, I will pre-install a conduit across the garden and through house ready to where I want it terminated.

The BBC will in the near future get rid of transmitters to aerials and expect all viewers to use the broad band network instead saving billions of pounds in maintenance and renewal costs. Progress?

Thread: NHS Covid Passport Scam
03/10/2021 22:42:20

I have read that they are taking your details and selling them to others who are not vaccinated and putting this on their NHS record so they can get a passport for around £800.00 a person including make of vaccine and batch number.


Thread: Spindle Bearing Wear Check
03/10/2021 22:34:37

They are 30206/P5 Bearings if you buy new ones Timken quality are £10.80 each plus vat. Have a look on the Chester hobby web site you can download the manual which lists all parts and information.

Hi Chris when you push on the bar does it return to zero. Also what is the finnish like, do you have a taper in the work when turning parallel. The bearings are taper type and should be adjustable with care and knowledge.

Thread: PM Research#1 Cylinder Can it be saved ?
26/09/2021 07:29:38

If you make a slug of cast iron to fit the slot that you have milled it can be pressed in and if you hit it with a punch it will expand and will never come out. You have to make the plug a good fit and you have to have a piece of round bar in the bore of the cylinder to suport the bottom of the plug. You won't have to re-machine the slot if the plug is the corect depth. When fitted you punch the plug with a diamiter pin punch along its length and it will be permanent and won't move although you may have to skim the cylinder bore as the plug may stand proud a little. I have used this method in many castings both cast iron and aluminium to repair all sorts of machinery and tooling.


Thread: Material selection or additional process
25/09/2021 20:33:41

Hi Colin. The black mild steel is too soft for a chuck key. I would use EN 40B which is a tough material or silver steel which will need hardening and tempering. Also I would make it from a larger diamiter bad and just reduce the 7mm AF end to allow a larger handle diamiter without weakening the key.


Thread: Stuart engine paint colours
