|Thread: Where's my Dykem blue gone - there's no need to read this|
Did you lay a curse on this thread Robin? I just picked up a bottle of blue and the top was loose. Blue floor, blue bench, blue lathe and blue hands.
|Thread: Removing a grub screw|
Bought a pin vice and drill bit set from Aldi a while back. Came with two sets of bits, I thought metric and imperial but no, left and right hand metric. Took me a while to work out why I wasn't making a hole
|Thread: ACME vs lead screw|
They are both trapezoidal Harry. Generally I think the difference is whether the machine is imperial or metric. Acme (named for the Acme Machine Company) has a thread angle of 29 degrees and dimensioned in inches, whilst ISO trapezoidal threads have a thread angle of 30 degrees and are dimensioned in mm. I suspect however that in the long tradition of mixing standards you can get metric machines using the Acme thread form or imperial machines using the ISO form.
|Thread: 'War Department' (arrow) Marking|
I'm always amused by MOD issue 13-amp plugs, which have an arrow on them to show which way up they go
In the workshop I have a set of metric spanners, feeler, screw and radius gauges issued to my father in the 70s. All marked with the crow's foot (the story passed down in legend within the Dockyard was that Samuel Pepys based the mark on a bird's footprint in the snow whilst trying to reduce theft) but accompanied by a letter saying they were issued as his personal property. This was done as part of metrication as fitters had been expected to buy their own tools, and all their BS/UN tools were becoming obsolete.
|Thread: DraftSight no longer free|
Look out for an email entitled "A New Era for DraftSight: Important Product Updates" which carries the bad news. The bit that this thread is about is in (their) italics.
|Thread: No 20 machine oil|
I had been looking at Alex Oils for SAE 20/ISO 68 and noticed that there are two alternatives, Lumach 68 Lubricating Oil and Lubron ISO 68 Hydraulic Oil. Given that they are both the same price, would there be any advantage to the hydraulic oil?
|Thread: Todays DUMBO award|
I wanted to reduce the diameter of a spigot but the part was too big for the lathe. "I know, I'll use the boring head" I thought. Set the tool facing inward, put the mill in reverse and got on with it. When I finished the job I removed the head from the arbor and started sweating. It was only hand tight but luckily hadn't unscrewed.
|Thread: Machinery Directive and CE marking|
Perhaps a remedy would be to approach our representatives in the European Parliament to remove the requirements for non-commercial builds in the same way as for boilers?
|Thread: Rulers - my pet peeve|
If it was plain on the back I would agree, but as both sides are marked there isn't a cost saving. I'm reluctant to cut down a 64R but it is starting to appeal.
I bought a 100mm rule, clearly marked, handy for working around a machine but only graduated on one face! Instead of the reverse being used for imperial, right-left measurement, putting 1/2mm on the opposite side of the rule or even a set of handy conversion tables, it just says "Axminster".
|Thread: Unusual miniature|
According to the ever reliable Wikipedia, Hornsby's patent was for a dual clutch system, not a differential.
There is a model of the Hornsby Steam Chain Tractor at a UK show on YouTube

|Thread: Long drills|
Your advice is exactly a day too late for me David, Iast night I shortened a part to allow the tap to reach the threaded portion, this morning I would have done what you suggest
|Thread: New Mill|
My son has an X2.7L The long bed is useful, and means that a vice can be left on the machine almost all the time regardless of what else is to be done.
|Thread: Sieg C6 / SC6 Spindle Nose and Arc Euro Trade Chucks|
Just in case anybody finds this in a search sometime, the two are not the same as the Sieg has a larger spindle nose, but I was able to fit a Sieg SC6 backplate to a Chester DB10 Super by making a cast iron sleeve to fit inside the backplate.
Lathe Sieg SC6 Chester DB10 Super (2019)
Spindle nose 52mm 50mm
Plug bolt PCD 75mm 75mm
Plug bolt hole dia. 20mm 20mm
|Thread: Dishwasher detergents|
If I had put my wife's Japanese knives in the dishwasher she would have used one on me! She won't even let me use the same waterstones to sharpen tools. Global for example specifically exclude "Improper washing and cleaning e.g. dishwashing, drip-drying" from their warranty (as I heard explained to a customer who was complaining that his were pitted).
Aldi tablets always did* the job for us just as well as premium brands, and we found the same applies to washing powder. Regardless of what dishwasher tablets or powder you use, I would suggest washing glasses by hand unless you really like the etched glass look.
*We got rid of the machine a while back - it took so long to build up a full load that it was spending most of its time as a cupboard for dirty plates. Funny thing is that after 30 years with dishwashers, I discovered I don't mind washing up...
|Thread: Free 2D drawing programs|
Can the moderators merge threads? It is as if two parallel conversations are taking place on the same subject.
|Thread: Tap and Die|
There is a 3/16 x 50 die on eBay right now, unfortunately the seller doesn't state the profile LINK
|Thread: DraftSight no longer free|
My apologies, I hadn't considered that my use of angle brackets to show keyboard commands would be processed as empty HTML markups. The real operations to draw a hexagon were slightly longer as below:
So far I have found that multi-line text from DraftSight is coming out as a single (very) long line, and that some linetypes haven't worked. Layers seem to be OK, but although it looks like QCAD can support multi-line text, and if not I can simply go back to the old way of entering one line at a time).
The biggest loss seems to be in dimensioning, as QCAD doesn't appear to support alternate (mm/inch) units, but instead requires the alternate dimension to be entered manually by editing the dimension. All drawings from DraftSight only show the first dimension when viewed in QCAD.
I think QCAD will be able to satisfy my needs but my first action will be to print all my existing drawings to PDF so I have a reference copy that I will be able to check if I need to edit them later in QCAD.
I'm a total beginner at QCAD and have only read the first few pages of the e-book, but this worked for me to draw line by line a hexagon with 20 unit sides:
What surprised me was that I didn't at any point have to hit
I get the feeling that with practice it will be as quick as anything else, and it is probably faster to learn, but it is going to take a while to get used to it as I have been using the same AutoCAD/DraftSight interface since taking my C&G on AutoCAD R14.
EDIT: to remove accidental winky
