Thread: Can summer car tyres be used in winter?
17/06/2020 07:31:54

I've always wondered what's so special about filling your tyres with nitrogen. After all, normal air is at least 70% nitrogen. Sounds like a scam to me. Same as using Argon in double glazing cavities.

Thread: Mystery TC inserts.

Just thought I'd update you as to use of the inserts. I made a double ended tool, which seems to work quite well. I tried it on a piece of rebar which is a pig to get a decent finish on, even using a freshly ground and honed HSS tool with cutting oil. The tips were held in place with 8BA screws.tip-tool.jpg

I then moved on to the item I originally intended using the tips on. This was in the May edition MEW and has been in my project file since.

When I first tried it it was absolutely awful. I had obviously got the cutting edge too high. Put the main block in the 4 jaw and took a light skim. When re-assembled and checked against the height gauge (just a metal cylinder of the correct height), it looked spot on, but a check with the finger nail showed it to be just a gnats below centre height. Tried a test cut and it worked well. Most of my turning is done with tangential tools, but this will come in where they aren't suitable. It joins my growing selection of specialist tool posts.toolposts1.jpg

While searching on-line,I came across this site which may well prove useful to those of you unaware of it.**LINK**

The mind boggles at the almost infinite number of different connectors that have been used.

Pin is 1.95mm diameter. The pin is eccentric and has a hex socket on the back. Rotating the pin releases or clamps the insert.

Thanks for that. A bit complicated for my intended use. I think I will use the KISS principal and use the nearest size screw I have, possibly backed up with a clamping arrangement.

I will report back with my success/failure in due course. Thank you all who responded.

inserts1.jpgI have this box of tungsten carbide inserts which I bought several years at a car boot sale. I am wanting to make some holders for them but am unsure as to the size of the fixing hole. It is too loose for 2mm and not big enough for 2.5mm. An 8 BA bolt fits but is still a bit loose. I just wondered if anyone can suggest what size screw/thread is used with these.

The inserts are 10mm on a side and 3mm thick.

Mine was the same. I cut the plug off and fitted a UK 13 amp. No problem. Mine had Border Force stickers all over the box it came in, so I assume it came directly from Italy.

Anthony I would format the SD card in camera rather than on computer

Hi Roy. that's what I did.

Thread: Storing & Documenting Your Tooling?
03/06/2020 19:06:26

I have a Bisley 10 Drawer unit to store various varieties of taps and dies and ER 25 collets.

Because I have damp problems in my garage/workshop most of my equipment is stored in plastic food boxes.

Drill chucks are also stored in a plastic box at the tailstock end of the lathe.

Standard drill are stored behind the chucks.

Special drills stored on the shelf behind the lathe.shelf1.jpg

Because of the damp, sensitive measuring instruments, gauges etc are kept in a cabinet which is stored in the house. The photo also shows two ring binders which currently list power tools and workshop equipment These contain print out of photos, user manuals and where possible purchase receipts. This is for insurance purposes (we all know what a bunch of crooks insurance companies are). It will also help my executors when I go to the great workshop in the sky.

Thread: What Did You Do Today 2020

Today I put the SD card from my camera into the computer card reader to upload some photos, to be met with a "this drive needs formatting" message. After a short period of panic, I did some on-line research and downloaded a Linux application called TestDisk. This successfuly recovered the files from the card, some several times and also ones I had deleted. I have now edited the photos into appropriate folders and formatted the card for re-use.

The photo I wanted was the one showing my now completed knurling tool, which is below.

I have had these for a few years. In fact I think I bought them at the last Harrogate Show. I have finally decided to do something with them.wheels.jpg

I made some arms and retaining pins/axles. I decided to make them removable (unlike my bought one) so I can change the wheels if needed and also replace the pins if they become worn.

arms1.jpg

Assembled them to see if they fit properly.

arms2.jpg

I decided to make a Quick Change Tool POST to fit them to. No flimsy, hanging in the air gadgets for me.

Trial fit looking good. Just need to make the clamping assembly now.

Thread: oscillating spindle sander help?
29/05/2020 09:17:09

Dry joints happen when the solder fails to "wet" the two parts of the joint. They are held mechanically in contact, but can fail electrically at any time. It seems to happen more with the new lead-free solder, than the old 60/40 lead -tin solder I used most of my working life. Such is progress.

The PCB looks like a 4 diode rectifier with suppressor chokes / capacitors and a couple of VDR's.

Nope! Cut the cable off and fitted a single trailing socket on the end and binned the 4 way block. (I'll probably get reprimanded for that. Should have recycled it.)

15/05/2020 21:06:41

It's was probably from an installation I removed when I was working, as the mains plug has a PAT testing label on it dated 2003.

Got a 4 way block with a 2m lead, from by box of electrical bits, to test my newly arrived bandsaw. Plugged it in and "pop", everything in the workshop went off. unplugged the extension and tried another one. Every thing OK.

When I opened up the 4 way block I found THIS.

What is worse, this is on the back.bs.jpg

How do they get away with putting a BS number on stuff like this?

Thread: Bandsaw advice
15/05/2020 15:13:26

I had an Email from Amazon the other day, saying my bandsaw was delayed and would now be delivered on the 26th of the month. I was quite surprised to receive a text from DHL this morning, saying they would be delivering today. About 1 hour later, it arrived.

fermi.jpg

As you can see it came with a european plug fitted. I don't have an adapter, so I cut it off and fitted a british 13amp plug to see if it worked. I hope I haven't voided the warrantry.

The saw looks well made but the user manual is terrrible. It has been written for every EU country and there is quite often just one line of English on a given page. I think some drastic photo copying and editing is called for to produce a useable book which will be considerably thinner. The only thing I can fault the saw on is the 20mm gap between the end of the vice jaws and the blade. It is now set up on the bench and I will be trying it out later.
