Thread: Which oil and oil gun
28/08/2019 15:21:36

I’ve got a flexible spout oiler like this one.

Works fine.

Thread: Lathe rigidity
25/08/2019 19:20:32

I’m sorry if this has been asked before but is there any particular reason why you aren’t using a lathe chuck rather than one on a Morse taper?

Thread: Any one recommend a supplier of 1/4 inch lathe blanks
23/08/2019 22:30:52

I got some 8% Cobalt HSS from Cromwell Tools. They were on special offer at the time so very reasonably priced.

Thread: Outrageous?
22/08/2019 20:09:59

Ah yes, I forgot about the 28 days for delivery! I’m not sure I ever waited that long though. I recently ordered some parts from a company. I asked if the prices were inc or plus vat and how much the shipping was for the parts I required. I placed the order online and got several email confirmations. A week later and the parts hadn’t arrived so I emailed asking if the parts were in stock? No was the answer, lead time is 30 days so you should get them in three weeks time. It would have been really nice if they’d told me that up front then I could have looked elsewhere.

As for eBay I’ve only had one poor transaction and although the pictures of the product were very misleading the full description was actually fair. I use eBay virtually every week for all kinds of stuff.

Thread: Torx head variant or faulty batch?
21/08/2019 15:46:41

I can’t remember the last time I had a dud fastener. The last bricks and mortar fastener shop I used quite a number of years ago told me that a lot of the stainless stuff I was buying like socket screws were coming from India. Actually I do remember some dodgy fasteners, they came fitted to my Chinese Lathe and also the mill! Easily replaced from stock at the time so I forgot about it.

I’ve ordered one of these, hopefully it will work ok.

There is a guy on eBay selling the 6mm polished cutters. Winning bids are normally around the £30 to £35 mark. This though is for three boxes of Ten inserts. I’ve now got a good supply of them. I bought them for use on wood turning tools for hollowing but I also have a profile tool for my metal working lathe. I also recently made a flycutter for my milling machine that takes these cutters.

Any chance of a link, or sellers name/profile please.
My ebay search fu seems to be failing.

Thanks Bill

Here you go Bill.

I know a couple of people that have got these and the winning bid is as said normally around around the £30 - £35 mark which is obviously a very good deal for 30 inserts.

Thread: Hex Silver Steel/Tool Steel ??
21/08/2019 10:29:25

Just looked at mine and they are octagonal so that confirms what others have said about tool steel. Being octagonal surely makes it more comfortable in the hand?

20/08/2019 17:54:34

Cold chisels make really good punches and can be had quite cheaply sometimes. The last batch I got were Eclipse branded ones about a foot long. They only cost about a quid each from the discount store.

Thread: LED Dimming
20/08/2019 14:25:58

I was originally looking at this.

**LINK**

As a standard switch plate it’s a bit bulky but perhaps I could remove the working parts from the plate.

As far as the dimmer I linked to in the OP it does say it’s a dimmer and also that it’s suitable for lamps?

20/08/2019 13:27:48

I’ve ordered one of these for a particular job.

**LINK**

And I may require a dimmer for it. I’ve heard of lots of problems with light dimmers such as buzzing noises and flickering. I don’t need or particularly want a “normal” light switch but instead will probably use an enclosure and a couple of IEC sockets.

Someone has recommended I use a variable voltage unit like this.

**LINK**

The only thing that concerns me is that it says 220 volt input so would this be ok for UK mains?

Thread: Grinding your own lathe cutters
17/08/2019 12:25:25

It may be a generalisation too far but I’ve found the polished inserts work very well and suspect they would be good for small lathes like the Sherline, in a suitable size.

Something like this?

**LINK**

Maybe even the next size up.

The Tangential tool pictured is version three, the one I use.

With retirement approaching I considered the relatively high cost of inserts compared to a piece of HSS. I made a small tool that took 1/8” HSS but it didn’t work too well. I got the angles right but I don’t think I ground the HSS correctly. I considered the cost of buying the Eccentric Engineering one would soon be recouped so invested in one. It worked very well with both round and square tool bits. And loaded with carbide easily deals with tough materials. One thing I didn’t like though was that the head was cranked over at an angle (they have now changed this). As a result I decided to make another one with a straight shank but I didn’t allow enough clearance around the cutting edge, this was V2. Version three is as you see it with plenty of clearance. Could it be made better? Yes, I’ve seen a version made by one enterprising individual where he simply flips the hole unit over onto a flat surface to set the tool height. In place of this I made and use a dedicated height gauge. They are fun to make and in my experience work very well for both turning and facing.

Flash is notoriously insecure, which is why most browsers block it by default.

Yes agreed. I thought Flash was dead, why is anyone still using it?

Have you heard of tangential tool holders? Lots of designs around if you want to make one and I am in the middle of trying to design my own. Eccentric Engineering make one, see the adverts on this site, and there are some youTube videos about tangential tools.

The big advantage of this type of tool holder is you only need to grind one face.

Adrian

This is the one I made. No plans just made it up as I went along!

Thread: Water pump shaft clearance?
15/08/2019 15:02:09

The impeller is made of some kind of magnetic material. I’m wondering if I can mount it in a collet and drill and sleeve it to get a better fit?

Might be a silly question but is the pump motor section full of water otherwise a dry running pump will be noisy.

Yes it’s full of water. Excess noise is often blamed on trapped air but there’s a distinct difference from the noise trapped air makes and this humming/buzzing noise. You can also feel the vibration through the housing.

The frustrating thing is that these pumps used to be virtually silent in operation when they were made in Germany. Not sure where they’re made now but they no longer have “Made in Germany” on them any longer.

looking on the net I’m not the only one to have this problem, lots of others have suffered it with this particular model and others in the series.

Its part number 7632600

I bought an Aquarium filter a while back and I had to send the head back because it was very noisy. It was returned with a new impeller but it’s still noisy so I’m now in contact with the importer. There is only one moving part on these pumps, it’s an impeller with a tubular magnet with plastic vanes. This rotates on a ceramic shaft. In operation there is a humming noise and vibration coming from the head. I have a similar unit from another vendor and it’s virtually silent. I’ve measured the ceramic shaft with a mic and it’s 2.48mm. Sorting through my drill bits I found the end of a 2.56mm bit just fits in the impeller opening. It doesn’t sound much but the gap between the impeller and shaft is quite noticeable in the hand. What would you expect a reasonable clearance to be for something like this. Anyone have any ideas? It may be that something else is causing the noise but I can’t think what that may be.

I’m not prepared to do it at the moment but next time I clean my other filter I will check the clearance on that just out of curiosity.
