Thread: How to choose a high quality end mill cutter?
29/03/2022 09:41:45

Have a look at Rennie Tools offerings David. I’ve been well pleased with the price, quality and service. You can buy from them direct or through Amazon.

Thread: LED bulbs

I don’t think the boss would be overly keen on the aesthetics of flat panels in the lounge. In fact I wouldn’t either! laugh

I’ve now given up buying LED lamps for the overhead lighting in our lounge. Trying to buy a cool white LED lamp with a light output similar to a 100W GLS isn’t easy it seems and the ones I’ve tried have only lasted about 6 months. I’ve wasted a lot of money and ended up with at least six lamps going into the bin. LED may be cheaper to run but buying them and binning them is most definitely not cost effective.

Another point about wind-turbines...

Do the raw materials for the synthetic-resins in the blades, the lubricants and hydraulic fluid in the machinery, the electrical insulating plastics and the high-grade (epoxy?) paints on the masts; not all come from petroleum derivatives....?

They do, which is why it's important to stop wasting oil by burning it. Oil isn't an unlimited resource that lasts forever. When it runs low there will be serious shortages. About 16% of the world's gas is used to make fertilizers, without which our great grand children will starve.

Joe correctly points out that wind turbines are also polluting and mentions 2 million tons of blade waste per year. Sounds bad, but that's tiny compared with the 32,000 million tons of Carbon Dioxide dumped into the air annually. (Five times more than in 1950)

Green may not be perfect - nothing is - but burning fossil fuels is far worse.

Well said Dave.

Thread: Tapping straight
24/03/2022 10:15:34

I do virtually all my tapping on the milling machine using a spring guide like those shown. If I didn’t have a mill I’d do it on my bench drill. Failing that I’d use a block to keep the tap straight.

Thread: Pressurised vs loft tank CH systems?

I must run off almost of a gallon of water before the hot water comes through and that is in the bathroom where the the boiler is about a metre away on the other side of the wall.

That doesn’t sound right.

When we had our boiler installed a few years back the installer specifically asked me if I wanted hot water “on demand”. He explained that the boiler would come on as required to keep the water hot in the system. I told him not to bother and even so it doesn’t take long for the water to get hot.

Only heating water as we need it rather than heating it and storing it in a tank definitely lowered our gas bills.

Thread: For those who live in the country
19/03/2022 11:17:35

I went to Tesco the other day and Petrol was £1.62 a litre and Diesel £1.74. No idea what the cost of Kerosene is though currently.

19/03/2022 09:54:57

Running cars on red diesel costs the exchequer enough in lost revenue. If they take the tax off heating oil I expect folks may start using that instead? That’s aside from that fact that heating oil is probably the most polluting solution for home heating.

Thread: Propane torch

As said Sievert are good. Best prices I found were at:

Thread: Spiral Taps

Why not sharpen them ?

Roy

I’ve try to sharpen straight taps before (it didn’t seem to work too well) but how would I sharpen a spiral tap?

12/03/2022 13:18:01

They weren’t cheap taps. Lesson learned at least for me. It’s about time I bought some new taps so I’ll get hand taps next time.

Thread: Hammer Handle Supplier??
11/03/2022 12:08:53

I read an article about hammer handles a while back and it seems grain orientation is not always correct. Hand selection in person being virtually the only way of getting the best material. Ash has only been the preferred material here for several hundred years so I suspect it’s more than up to the job. Another timber, other than Ash or Hickory is popular in Germany but I can’t remember the name of it.

Thread: Lathe Tool
10/03/2022 10:14:42
Posted by John Reese on 10/03/2022 00:39:33:

I have one of the Chinese imports. It works quite well on my 16" lathe. Because of the insert geometry it may not work so well on smaller less powerful machines.

It depends on the type of insert. The polished inserts should be fine on almost any size lathe.

then noticed they could match anybody’s cheaper price,

Should have done some homework before purchasing. If I make a mistake and pay too much, that is history. My own fault and I learn for the next time, but I don’t go grousing about someone else when it is my mistake.

Learn from it and move on.

I couldn’t agree more!

It doesn’t look much like rifling marks.


Thread: Spiral Taps
07/03/2022 12:22:51

I bought a couple of these some time back, an M5 and an M6 and they are now very reluctant to cut a thread. I’ve resorted back to my old hand taps that have cut many more threads. Is this normal for spiral taps, do they wear out quicker for some reason?

Thread: How hard is gauge plate?
07/03/2022 12:19:40

Gauge Plate may be annealed but it can still be tough stuff. I’ve broken an M4 tap in it before. I’ve also stripped the teeth on a hacksaw cutting it due to some kind of hard inclusion.

Thread: Lathe Tool
26/02/2022 21:42:57

I bought a similar tool but to take TNMG inserts. It’s fine and was good value for money. The tool holder is 16mm but I trimmed off 2mm from the bottom to fit my Mini lathe four way. It’s tough steel but can be cut with a carbide end mill. I got some cheap polished inserts for it on Amazon for not much money and they work well.

Thread: Inverter interference
24/02/2022 09:36:43

Thanks folks. Thanks Robert but I’m in Dorset and I don’t have free access to the equipment anyway. I can only go on the information I’ve been given. As I said in the OP I’ve been informed it’s mains not airborne interference. I think I’ll pass on the links to the two items mentioned and let them make a decision. If it’s solved I’ll come back with the solution in case it’s of help to anyone else.

“We know our inverter causes EMI but we’ve decided not to deal with the issue”

Industrially the VFD is considered to be a component, which is used within a larger installation. The need for EMI filters will be considered taking into account the whole installation. That may mean a VFD has it's own filter, or a filter is shared, or one isn't needed. Consequently most VFDs do not have a built-in filter.

Andrew

it’s not industrial equipment, it’s a small wood turning lathe offered to home users.

Thanks to everyone else for your comments. There seem to be several possible solutions but at least one may require the services of someone more experienced with electrics. Possibly the simplest solution would be to use this with the camera?

or maybe this.

Any thoughts on them?
