|Thread: Air Compressor Warning|
I am very wary of big bangs having been injured in one as a kid so I must admit to being a bit windy watching these vids especially as my 5/6 year old 25 litre PowerCraft budget job lives under a bench within a few feet of my carcase.
Since I replaced all the connectors on the compressor, hoses and tools with PCL standard connectors I am no longer cursed with air leaks. Since then my normal pattern of usage is to bring the compressor up to pressure then switch it of at the mains socket. I mainly use it for blowing out machined work and using it thus a full reservoir can remain usable for a week or two. Repeat as necessary.
The tank collects very little water – most times I undo the drain I get air only. I wonder if this is because the workshop is heated, insulated and double glazed? I have just been up there and unscrewed the drain and only got air – if memory serves right the last time I undid the drain would have been maybe three or four months ago.
I am not offering any advice or recommendations as to the safe and proper way of using a “bomb” merely my way of doing things.
This is the first time I have ever seen a report of one of these budget compressors going bang. Hopefully it’s a bit of a “one off”.
One final thing and call me a “wuz” if you will but when I DO power the thing up I always retire safely to the house while it is inflating . As soon as that deafening “BLAAAAAR” stops I resume normal service.
Rik (still wincing at the split reservoir in the vid)
We have two of these, one is plugged into a socket in the workshop and the other by the side of my wifes desk down in the house. If either of us needs to holler she just presses her button or I can press mine which hangs round my neck on a cord.
Alarm volume is more than adequate and the units strobe lights are brilliant for the mutton and jeff. Best of all - they are cheap as chips!
Only ever used once in anger when we had an unexpected visitor and I was summoned to come and open the bar .
|Thread: Digital Height Gauge Recommendations?|
I bought this 150mm digital unbranded version new and cased from a bloke standing behind a pasting table in the middle of a field one gloriously hot Sunday afternoon some years ago - £30 if I remember correctly. It is smooth, accurate, very reliable and a pleasure to use. It lives and works for most of the time on top of a 12" square granite inspection plate (another car boot acquisition) where used in conjunction with a box of older Matrix imperial slips I can - for instance - mark out in confidence without having to rely on my ropey old eyes.
I would recommend one with a carbide scribing jaw for obvious reasons and try and remember to turn the power of after use, that way the battery will last "forever".
|Thread: Warco BH600 drive belts|
Hello George - belt from motor and spindle drive belt are the same. This is what is on my BH600G:
If I ever need a belt I get mine from Bedford Bearings Ltd. 01234 271127 - they are my local experts.
|Thread: Three Cylinder Steam Aero Engine|
John - I am quite sure I could rustle up some suitable bits for you FOC but even then I fear the postal charge to Canada would be uneconomical
Another glimpse of a 9" tall seven cylinder radial steamer in my small collection here:
Thanks to MichaelG for the book recommendation. I purchased it at the time.
Good work being done John – be nice to see it (flying?) when you have finished.
|Thread: 3 leg hone|
I have never used one but a place where I worked years ago did. With the hone fitted to a thing like a very large two handled electric drill the fitter would hone a bored cast iron cylinder to take a cast iron piston that I had ground for him. Pistons varied in size up to 7" diameter and 8" long. The point I would like to make though is that of all the fitters, only one of them had the knack of getting it REALLY right. A hot sweaty job in the summer, Pete certainly earned his wages doing that job.
|Thread: Mery Christmas Everybody|
‘Twas Christmas day in the workshop and all was peaceful and quiet
when the door caved in with a dreadful din and there stood Neil Wyatt.
“Seasons greetings” was his wish - to us and all our dears
The same to you Neil from us lot “The Model Engineers”

|Thread: Dial Graduations|
Martin - I am doing something similar at the mo on a tiddly RECORD ML-10 lathe. A nicely made lathe apart from the graduated handwheel dials which are made from black plastic. I am remaking them in ally and the grads are being done in the lathe with a broken 6mm carbide cutter ground with a pointy end.
There are forty grads per dial and my luck was in when I found I could index from the first 40T spindle gear on my Warco lathe.
When I have done the grads I’ll need to do the numbers - “0” and “0.5” at 180 degrees to the zero. This will be done on my small ISEL CNC machine with the dials mounted on a stub mandrel and held in a 5C collet block.
The only problem here was that I do not have a 4th axis for rotary machining. I have overcome this by designing and making a small (6mm dia.) spring loaded drag engraving bit which I have tested on 2.5mm digits and it works a treat.
I need four dials to complete the job but I I’ll make five – one as a spare. That will be quite enough graduations for me for some time thank you very much.
|Thread: On 'yer tod over Christmas?|
I’d never heard of the Silver Line until just now. I read the link and thought it might be of interest to some of you on here who live on their own and might not be exactly inundated with friends and family over the Christmas period.
|Thread: Case hardening a part with tapped holes.|
The bloke in the heat treatment plant at the last place I earnt a crust used to stuff fire clay in the tapped holes to stop the threads from hardening.
|Thread: Grizzly ? .......... not just a lathe.|
I first heard this many years ago and forgot who performed it. Having undertaken the task of unearthing a copy I was delighted to uncover a YouTube version this afternoon which for me had for so long been buried from sight. Hopefully this will help raise your spirits amid the rigours of our nationally imposed stiff disciplines.
|Thread: Free inserts.|
Stephan, can I go into the hat please.
|Thread: Have You considered getting a 3D printer|
I don't have one yet but I am waiting for the Sovol SV03 to become available then I'll treat myself. It will live in my study though as there is zero room left in the workshop (unless I screw it to the ceiling).
Like Buffer I wear specs but for closer work I use an Optivisor as well. Yes, the genuine Optivisor is a bit pricey but for me it was money very well spent.
|Thread: 2021 - ME shows and all that|
Is it to much to hope that the jabs we are being promised to protect us against the pestilence will allow things to start getting back to normal next year? It would be lovely to contemplate a visit to a ME show or steam rally after emerging from "the bunker".
You may say I'm a dreamer, but I’ll bet I'm not the only one
|Thread: Ball ended handle - how to|
The last lot of ball ended handles I made were from silver steel rod and ball bearings thus:
Cut silver steel to length and thread as required at one end. The other end was first faced in the lathe and then dished with a ball end slot drill roughly the same diameter as the ball bearing.
Now take a tiny piece of silver solder and hammer it flat to produce a small “flake”. Place the flake on a piece of softwood and give it a whack or two with a hammer driven ball bearing. The aim is to produce a small dish. Pickle the silver steel hollow, ball bearing and solder “dish” in something like very warm / hot lemon juice for a half hour, dry all.
Next, grip silver steel rod in vice jaws vertically with the hollowed out end uppermost. Put a tiny amount of flux in the upward facing hollow and place dished flake on top. Apply a little more flux on top and gently push the ball bearing down on the lot.
I used a fine nozzle on my propane torch to heat it up. Try sitting down while you do it with your eyes level with the ball. Watch carefully and remove heat source when the ball moves slightly into its bed of molten silver solder.
Cool and polish – job done.
Others may do it differently, with paste for instance, but not having any I did it my way
With due acknowledgment to Harold Hall and his design at : Grind Rest, Advanced (homews.co.uk)

|Thread: Wanted - cannot make the trip!|
Twice in the last couple of days I have tried to reply to the same chap in the "WANTED" classifieds and get the box that tells me that the message has been sent. However, if I look in my sent box there is no sign that I have messaged him.
This is the first time that this has happened ever. I've never had a problem before - any comments?

|Thread: Trunch Trojan|
Well done Arthur it looks good to me - and for a first project - VERY good. I hope you won't let the miserable "fixtures" criticisms delay the start of your second project. NIL CARBORUNDUM !
|Thread: For the latest in PC fashion! (Anyone here with a Master's Degree?)|
VIZ was very good at lampooning this sort of posturing "wokeness" scrawled in the OP's link. Millie Tant would have been proud of this bunch of prats.

|Thread: Medical needles|
I am down to my last two hyperdeemic nurdles and have found them very useful over the years. It had never occured to me to use one for sucking splinters - thanks Jim, much more precise than a solder sucker. You've got me thinking now about solder suckers and blackheads, would that work I wonder?
