Thanks everyone for all the nice replies yes

What a great project. Top quality. I see you even stamped the inside of the lids.

Steve.

Thanks Steve I did mark them up well spotted! think they call it a makers mark, my initials, the year date and a Norton roundel punch I made for my Norton engine plate. I hope they don't mind!!!

They are really nice, it must be satisfying knowing that they are going to be there for posterity, too.

..if the flow needs a tweak, I wonder whether a (tiny) breather hole might help - it's only a vague musing, I've been experimenting with wicked burners recently and found it doesn't take much 'vacuum' to overcome capillary attraction..

Great job..

Thank you, a lot of the original oil pots went missing while the boat was laid up for many years rotting, before the restoration got under way. So hopefully my oil pots will still be there for many years to come.

I carefully designed the lid to be a rattling fit to avoid any vacuum haha.

I've been making these large capacity oil pots over the last few weeks (months really!), and finally finished a batch of them, with the design slightly evolving as time went on.

Ten of them will fit the double expansion steam engines on the 1903 Steam Tug Daniel Adamson, some more are needed but I'll make those at a later date.

All brass construction, silver soldered together with worsted wool wicks for the oil feed.

I did a test on the final voyage to its winter mooring in Liverpool and they worked quite well, maybe needing a tweek on the wicks to adjust the oil flow. And maybe the smaller one is about the right capacity, won't be able to check until next year though!

Here is a video assembling the oil pots.

Thread: KLG Mystery Object.

It looks well made and strong enough to open a bottle of Guinness... or two.

It's one of those little workshop oddities I'm going to look out for!

Looks like a bottle opener? One of those freebie corporate giveaways?

Thread: Clockmaking on YouTube
12/09/2021 00:03:30

I have subscribed to your channel Tommy, although I don't have much interest in clock making I find your videos interesting and informative. I think it's the only clock making YouTube channel I watch, apart from click spring.

I enjoyed your workshop tour, some nice tooling there, keep up the good work

Thread: CNC Knurling
06/09/2021 10:26:09

That turned out nice, the crests look sharp and well formed.

I did something similar with my 4th axis to produce spliced thumb nuts. I used the corner of a 6mm end mill. I wonder if it would work on a spiral to produce a knurl like yours?

Thread: Threading myth .... busted!
05/09/2021 23:06:28

I forgot these photos were in my album, must have used them when this topic came up some time ago.

This is the method in 'Newnes Engineers Pocket Book' explains it all quite nicely. The technique is mentioned in bottom of the first page and carries over to the top of the second page.

'the tool is advanced slightly several times during the operations, but allowing the tool to cut all over on the last one or two cuts to obtain a thread to correct form'

That'll do me because that is the way I have always cut threads on a manual lathe, nice and simple!

Maybe I'm just watching too many YouToobers using this convoluted method, it does get on my nerves when they make a point of adjusting the compound to 29 degrees for a UNC thread, as if it's the only way to single point cut a thread!

IanJ

Joe Piecynski in his latest YouTube video has busted the myth of needing to cant over the compound slide half the thread angle, to carry out single point threading. Although I think he has missed a trick! He advances the cross slide, set at zero degrees to full depth, but without moving the top slide.

Over the years of machining and during my apprenticeship I have never moved the compound to half the thread angle, and have always set it at zero degrees, the cross slide is advanced an appropriate amount, and the top slide is advanced a little bit every so often, maybe a third of the depth of cut, or a thou or two. A couple of spring cuts will finish off the thread nicely, by cutting on both sides of the tool.

Depth of cut is easier to gauge too, because the cross slide is advanced into the job to final depth.

I'm glad someone has at last attempted to call out what I think is the over complicated method of adjusting the compound to half the thread angle!

Thread: Rare Parkson CNC conversion
13/07/2021 20:32:44

Looking forward to seeing the pictures Yuri, my KX1 runs on Mach3 and I would like to try Mach4, so it will be interesting to see how you convert your machine to Mach3.

Any reason why you didn't go for Mach4? I only ask because Mach3 is no longer supported by new fangled solutions.

Thread: Taps and Dies
13/07/2021 20:24:23

That set from RDG looks good value, I have a similar set and it cost over £60! One complaint is that the dies are not split dies, so you can't expand them a little bit in the die stock, but they cut great because they are ground HSS.

The chronos set looks like they only come with taper taps which can be a pain when tapping a blind hole. And you get a lot of taps you may never use.

So if you are tapping metric threads I would go for the RDG set.

And like the others have said, metric course is the standard metric thread.

Thread: Making an adjustable vice stop

Thanks for sharing the video Steve, if your results are anything to go by it's given me the urge to try anodising. And I didn't know of that alternative to sulphuric acid.

Thread: Spiral Milling
16/06/2021 18:58:04

Watched your video last night Nigel and was suitably impressed, it's one heck of a helix!

Just need a couple more videos now, one of the throttle operating the carb, and another one on making the toothed belt pulley, looks like drilled holes and round bar did the job?

Oh no!!! I've got a rather lovely Mathmos Telstar lava lamp, it uses halogen lamps. Looks like I need to stock up!

Thread: Hobby mill advice
04/06/2021 23:59:12

The sieg sx1lp is the upgraded version of my sx1, and I am always pleasantly surprised at how it survives my abuse! It is a sturdy little machine, mine has the pointless tilting column, never used it, so the fixed base is a bonus.

I have made motor cycle parts on it and probably oversized parts too, but I did upgrade to the larger 400mm long table which is now standard on the sx1lp

So yes the sx1lp is a good choice, considering your space limitations.

Thread: Taper due to tailstock height misalignment.
04/06/2021 23:40:43

Seems to me that it all depends on where the tool is held. If it is held vertically, 90 degrees to a normal toolpost, such as in a vertical milling attachment on the cross slide, and the tail stock is too high, it will produce a taper just like a tool held normally in the tool post would if the tail stock is skewed left or right.

Thread: Hydrogen home heating
18/05/2021 18:37:57

Interesting topic, I think Hydrogen is the future fuel, even though the chemical industry has been using hydrogen as a by product of chlorine manufacturing for over a hundred years.

There is a lot of activity from companies like Toyota and recently JCB developing hydrogen powered piston engines. And there is a trial in NE UK with a mix of natural gas (ch4) and hydrogen into home boilers.

Hydrogen can be made from a variety of raw materials, such as methane (ch4), only problem is capturing the waste carbon. Or water which only produces oxygen as a by product.

And of course nuclear power will provide the electricity for electrolysis with Rolls Royce small modular reactors in every town.

Exciting times!

Thread: Making a knurled thumb wheel
09/05/2021 11:43:11

I viewed the video and thought it turned out nice in the end, there are many ways to make something. That video is his way of making that particular piece.

I have subscribed and made a comment, thanks Steve and keep on making the videos.
