Thread: I think its sold

Frustrating .

Take the time to answer a FOR SALE advert only to be told -- I think its sold.

But if it is not, I will let you and other interested parties know.

Others ??

Been there done that TWICE. I wish members would remove the ad promptly once an item is sold.

Some may need a sharpen but no harm done giving them a try. Even if the tips are shot the flutes may be ok. I would say a good find. These are the kind of things I like to find as the HSS itself is still useful as lathe tooling when attacked with a bench grinder.

Drill a 8.1mm hole through a length of 20mm or so square/round bar set that in the jaws and push your rod through as required. You could drill & tap through the guide for a clamp screw if you feel one is required.

Thread: Wire wicks

I did a couple of other experiments to test some of the theories that were posted.

Lifting by capillary action and syphoning.

I suspect the syphon is broken because the two wire examples touch the container lip. It isn't broken in the multi-strand wicks because the outer threads are lifted over the edge. If so, the single wires might work if they were held by a firm base that hooked them clean over the lip.

Possibly the viscosity, weight and how well the oil sticks to the wire matter too. Could be a lighter oil on a different surface would be OK

My test does not use a tube on the inside of the oil pot and I don't believe it is a syphon action that lifts the oil. On some large engines the tube is 1/8"-1/4" diameter and 2"-3" high and open to air at the top. Somehow, the oil has to be raised by the wick on the outside of the tube

The test below has the wicks held at the base and hooked over the lip without touching the cup. The 1st is solid copper wire, the second plain steel with no coating on its surface and the 3rd is multi strand copper wire (from electrical cable).

Lighter (hydraulic) oil was used this time for the test and each wire coated with it to wet its surface.

Sfter 12 hours nothing happened.

In this test the first wick used a solid steel wire wrapped tightly with wool yarn..

We don't have worsted wool in Australia and I used a local lambs wool knitting yarn. ( Worsted is a high-quality type of wool yarn. It is named after the small English village of Worstead, in the county of Norfolk)

The second wick is one strand of the copper electrical wire, bent in half to make a small loop and twisted together. The wool passed thru the loop and roughly wound around the twisted copper wire. (this is how I make wicks for our full size traction engines)

Both of these transfered a similar amount of oil.

I believe the wire wicks work better when the free end is not touching the base and the oil allowed to drop off the end. This allows for a better pull by the wicked oil. Also the wick needs to be wetted at the start of the cycle so the run off starts the syphon action.

Thread: Lathe change gears vs gearbox
21/01/2022 13:07:03

I would vote for the Boxford AUD (as I have one). Whichever lathe you choose make sure it comes with the possibility to cut metric and Imperial threads. For example you need a 100/127 gear ( or a variation of) for an Imperial Boxford to cut metric threads. Also if you go for the AUD make sure you get the change gears that should be with it. Not sure on the Myford but plenty of members can point you in the right direction.

Does a bare wire work as a wick ???? I have my doubts.

..............

There's no point saying it doesn't work, it plainly does, what we need to know is how. Capillary rise doesn't need a tube.

I am given to understand that once the wire is wetted surface tension drags the oil down the wire. A bit like pulling a string the end will always follow. regards

Thread: 1st milling with the ZAY7045 Milling machine-Question

Although my lathe has got a flood coolant system on it I generally use a squirty bottle when needed as the flood makes far tooo much mess. Same on the mills unless using a big face cutter then I use mist coolant. I got fed up with wet floor, bench etc with flood coolant. On Ali I use a WD40 squirty bottle.

I have a very old stationary engine of unknown make that has wire wick oilers. As it is a non runner I have never tried them but they looked original so left them as is. If it had been a runner I may have thought "what idiot put those in" and changed them to cord. We live and learn. I subscribe to Robs channel and he does expel quite a few myths on brazing, casting and a few other things.  He also builds engines from scratch.

Thread: My next project

Neil, The protractor in your picture above or something very similar is on my to do list ( steal idea) for the cutter head tilt.

A little update. I machined the spindle of the head down and made a sleeve for it to enable me to try my Stevenson ER32 block as a temporary measure. I was going to use a Cutwell long shank ER32 holder but it has a 10mm hole up the centre. This brings some difficulties when trying to fit the dial and handle to it. So thats on the back burner for now. When I need to do flute sharpening I will revisit this part.

The rectangular mounting block for the head on the compound overhung each side of the swivel by 0.040" so milled it down so there was only 0.005" overhang. This will make it easier to fix the hinge plates when I get them done.

Am now working out the dimensions for the hinge plates that will be fitted to the sides of the block and be swivelled from the compound. I will try to incorporate some kind of protractor similar to one in Neils post.

The compound is not quite as well made as it first appeared. Nothing was square and looked if it had been sawcut and filed to shape. The block on the top was out by about 3 degrees so I had to sort that out. Now it is all square I can get on. I mounted the head to make sure I had enough clearance to sharpen cutters up to 16mm.

A few pictures follow.

I have trawled through my countless calculator books and have come up with nothing. Also spent many hours on the internet since the first post and nothing found. As a collector of Mechanical calculators and slide rules I will be very interested to know its origins & usage.
