Thread: Air Compressor Warning
24/01/2021 12:46:56

The tank drain valve on my small compressor is left just cracked open all the time. I very rarely use it for more than a few minutes at a time. In 10 years it most probably has less than 15 hours running on it. When I switch it off I always listen to make sure the air is bleeding off and hopefully any water that has accumulated with it. Maybe a waste of £ leaking air every time I use it but I am sure that it has been drained. I also made sure when I installed it that the drain was at the very bottom of the tank. When you look at some tanks the drain is not actually at the very bottom.

Hi TUG. My comments were not directed at you either. My problem is that the OP posted a picture with no context to it whatsover. At least the post has given us something to occupy ourselves with whist sitting on our bums.

NDIY. " Following the thread, I was almost thinking old iron had another nom de plume....🙂" Not guilty mlud. smiley

Hi Oldiron, all you see is all I have, it was take it or it goes it the skip, where I used to works years ago.

Regards Nick.

Nice to have though as is. I only use mine on my surface plate as an indicator stand as it is nice and heavy

Hi, here's a photo of the Mercer 108/421 that I have. Looks a little different than the O/P's one.

Nice box Nicholas. Have you got the platen that goes with the base for comparison measurements? I have one some where but not sure where at the minute.

We have one of the base castings at the museum, I had an idea what it was, but have never seen the whole thing. Our one has a tee slot rather than a vee. To make ours more useful, I milled the rads at the base square so it could be clamped down to the mill bed. I also drilled three holes through the slot to use bolts to hold it down. We already have some tee nuts which fit, I cannot remember what size they are.

Possibly a Starrett 665JZ indicator stand.

I see nothing wrong in this setup, especially to generate 3 pages of comments!

clamping.jpg

2 clamps on the ally plate plus 2 holding the casting down onto the plate onto the bed. He's drilling a 3mm hole! If it grabs what will fail first, the clamps or the 3mm drill bit? I see no rotational forces there that would creates a catastrophic fail.

I've watched most of Ades' videos and he knows what he is doing unlike some others on youtube.

Roger

I totally agree Roger. Exactly what I said in my 1st post. No problems here that I can see for the job it is doing. regards

One of the things that I really like about Youtube is that it is largely free of censorship. If you search around you will come across people operating at different skill levels doing things from the incredible to the downright dangerous. Long may this continue. Anyone who blindly uses it as an educational tool will sooner or later get more education than they bargained for!

It should be pointed out that this is a video made by a man in his shed. He doesn't have the resources of the BBC and isn't claiming to be any kind of authority on either machining in general or model making. Whilst I haven't watched this particular video, I have watched other videos by Ades Workshop and have thought that he seems competent in what he does.

He currently has around 100 hours of video on his channel, all there waiting to be scrutinised and picked over by the more learned amongst us.

I would suggest that before criticising one should consider making videos of their own, that way we can all learn something.

Regards.

David.

Here here David. I agree 100% Well said.

Go on mate you know best load of know it all’s on here I take it shouldn’t have bothered lol the 2 db8vs where defective lol it’s a well documented problem on this forum that’s why I joined but never mind bunch off geeks

Sounds like you were unlucky with the lathes if you were doing a perfectly good job. (which I doubt) A lot of people on here have many years of experience but you seem to know better. Lots of people have turned out excellent work on worn out old bangers of lathes. It just takes experience and getting to know the lathe. I dont think you have earned the right to call any forum member a know it all or a bunch of geeks until you get some experience and a better attitude. A very childish attitude methinks.

Why the heck would you need a silencer on an air rifle anyway ?.

Thread: Water pump for spindle cooling
22/01/2021 14:25:18

I put a standard 12v submersible caravan water pump into a diesel delivery system for a workshop heater for a friend 15 years ago and it is still working well. The pump was pushing diesel along a 1/4" bore copper tube. The burner system has a return to tank similar to a car diesel engine system. I did put a tee in the line just after the pump to bleed off some of the flow as it was far more than needed. Once set it has worked perfectly. There is a relay and power supply activated by the heater control system for the pump. Maybe somethinglike that could help you out.

I believe that a major factor was the EU prohibition on dredging waterways. I had hoped that with leaving the EU this would be rectified.

Brian

Wel,l early days yet Brian but lets hope things improve. The problem is all the "greenies" that say you cannot clean/straighten or clear river banks to aid flow and stop backups. It should be made a priority to clamp down on developing our ancient flood plains. AND bring back the beavers to make a few more dams upstream to slow the flow. smiley

Was this demonstration supposed to be a means of “teaching beginners” (like recently came up in a thread?).

It does appear that one step on the clamps might have been in use. But seeing that, one might wonder why there are seven(?) steps provided? One might wonder why they provide so many steps? Beginners might not wonder at all?

No claim to teaching at all as far as I can see. Just a "this how I did it video" . I have not seen any hobby machinist video's that says "this is how youi must do it". In fact many point out that they do not know it all but it seems some on here profess to know how everything should be done. The back story should have been shown to put this into context.

Sadly, when a photo is posted on t'internet, there is no discrimination for it to decide whether the viewer is knowledgeable or a dobbin waiting for an accident to happen.

Regards Ian.

Without the back story who is say whether the setup is bad or not. My gripe is that the OP goes on about milling side forces etc etc when it has absolutly no relation to the setup. That is why the back story is important.

As I said just another fake news story.

Clamp bar looks level to me so ok to use, what I don't like or do is put the step blocks straight onto my precious ground table, in industry & now at home I use surface ground 6 mm hardened steel plates to spread the clamping load, just a little foible of minewink

Tony

I agree Tony. I use strips of aluminium under clamps to save the bed.

Small hole or not, why not use one of the other spare stepper blocks underneath, then the system can be used as was intended.. John

There is no reason that the clamp cannot be used on the top step. The forces are straight down in this instance. You would have to overtighten the bolt and bend the bar before it slips off. This is a case of selective reporting of which there is way too much these days. Taken out of context it seems much more dangerous than it actually is. We have all used dodgey clamping methods we would not admit toat some time or another.

Pity you did not mention that this was a clamp on a very small drill operation and not a milling operation. The operator who is a very experienced machinist was drilling a pilot hole to affix the castingto a base plate for machining. The clamp was removed as soon as he had drilled the hole. No sideways forces whatsoever were involved. You should have linked to the video to allow people to make up their own minds.
