Thread: USS 'MONITOR' engine build

Probably better to use These on HMEM's site, Julius de Waals cad tends to be inaccurate and not build tested, just my own personal view

Thread: 1/4" " angle Drive In Hydraulic Grease Nipples
15/01/2023 12:54:25

Here are some photos of the grease (oil) nipples showing the reason why I need 1/4" angle drive in ones.

This photo below is of the front of the saddle just below the crossslide handle:

saddle front.jpg

This one is of the top front of the saddle nearest the tailstock, difficult to photo but there are 2 here:

And the last is of the top back of the saddle and is the hole furthest in:

I don't want to drill out and thread for the next size up as I don't want to risk getting cast iron swarf into the oil ways.

No probs Nigel, I'll take some pics of what my issue is tomorrow

"With that, you largely remove the worry about tightness of fit, and you may be able to make a suitable set of oilers more easily than trying to modify bought ones."

I've already said that they are for oiling about 7 posts above, I didn't imply grease just that that is what they are called.

The problem with the metric ones are that the 6mm is too small and the next size up (8mm) is way too big even to trim down.

Would these style of push in button oilers work for you?

Again they need a straight on connection and yet another pump gun

It really is a requirement for preferably 90 degree or 65 degree max angled lubricators.

Are you sure they are grease nipples? Drive in lubricators would be subject to up to 4000psi, and that seems a recipe for disaster. Most lathes do have some sort of grease nipples, but they are usually oiled, not greased. The Smart & Brown model A has about 10 nipples which Mike modified to accept the nozzle of an oil can. Getting rid of the grease which was used in error in the past is almost impossible without complete dismantling and cleaning.

They are called Grease nipples but are also used as oil lubricators, at least on my venerable lathe as original fittings

Something like these??

This outfit claim to do them too, but the part numbers aren't helpful

I have messaged Kingfisher but their box quantity is 2,000! they do say they do smaller box quantites but how small? Harrison don't do angled in 1/4"

IF I understand correctly You want a 1/4" drive in nipple ? What angle 45 or 90 ? Nipples are available in many threads, 1/4" BSF, and UNF 5/16" BSF & UNF, 1/8" BSP, 6,8,&10mm x1. Why not tap the hole? All these sizes are readily available. Or carefully grind the thread off a 5/16" one. Noel.

There is a good reason why I need angled ones and that is I don't have a straight in access to these positions so no chance of redrilling and threading for them, turning 5/16" ones down is an option but I just thought I'd see if I could get the correct ones first.

Thanks for the reply Martin but read the title please, I stated drive in, threaded ones are not an option.

I have a need for 5 of the above for my Denham Junior lathe, I've searched on Google and only found 1 trade only supplier that has them (i have contacted them in hope) but does anyone have some or know of a supplier or even a work around?

Thanks

Thread: Another EVRI calamity.
14/11/2022 11:06:11

I purchased an air fryer online from the brands' website last weekend, I was notified by EVRI that they had the parcel on Monday and gave the tracking number, at 09:48 a message appeared on their tracking stating there was a delay and it would be delivered asapp, it got delivered on Friday!

Our delivery man explained the reason, the delivery of air fryers had been locked in the secure area until the manager came back off holiday as there had been a spate of air fryers going missing, early xmas presents from the warehouse staff maybe?

I had a quick look - it's very similar to the JS one I made. I guess they all are to some degree. I'm in the lucky position of having made one for a friend my 'payment' was a pile of materials to make myself one so I have the opportunity to apply 'lessons learned' second time round.

Nice one, always good when a plan comes together wink

Mine was more than paid for when my mini mill sold for asking price. devillaugh

I'm using it on a 72" x 2" belt sander, I doubt it'll be running more than 10 to 15 mins max at a time.

Roger

Is it the Jer Schmidt design?

It's based on the Made By Dad design Lindsay. It is really solid but I had to play with the dimensions a bit to get the belt to fit.

Looking more closely there is paint removed under two of the screws holding the frame down.. The damage to the sealing edge must have been before they painted it. There are different views on using screws to provide a primary earth path. A lot of standards won't accept using the shank of the screw, it has to be a metal to metal contact or a earth wire / strap.

This is in my hobby workshop Robert, here's a couple of photos of a resistance test between the vfd earth and a fixing bolt and the sander table.

The whole belt sander will be bolted through a steel base which is earth bonded to an earth running round the workshop and back to the mains.

Is that "earth" connection actually connected to the frame of the motor? It looks like it goes to the terminal box housing which looks like it's plastic! In particular there is damage to the edge where the cover fits and it looks like gray plastic not diecast alloy.

It's worth checking with a meter. Good to see you are using SY cable and proper ring tags yes

No it's a cast box with full continuity to the motor and also into the sander its bolted to.

I'm currently wiring this motor to a vfd and my query is there are 2 thin blue wires ending in a small connector as below, in the top left hand corner, are these for temperature sensing? otherwise what are they?

. Last year the dehumidifier was generally run for two hours each night which cost about 7p. This coming winter the cost will likely have more than tripled. That is why I intend heating with a chinese diesel air heater and using the dehumidifier less.

I've been running my chinese diesel air heater on kerosene bought at the pump into 25 litres cans, last lot cost me 50p per litre and I buy 99 litres at a time, why 99 litres? 100 liters or above require a form declaring usage to be filled in). I've found that the glow plug and combustion chamber remains clean and I'm probably into the low 400 ltrs now.

It takes the chill off wink and the shop remains dry as now condensate is produced.

I have the same m/c and an ER32 collet chuck, I use the ball bearing type collet chuck and find I can put the m/c into it lowest speed and tighten the chuck onto the cutter and its fine for machining, also loosen it the same way. My chuck body also has flats on it if I need to use them but are very rarely used.
