Thread: Where's my Dykem blue gone - there's no need to read this
18/04/2019 14:29:53

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
17/04/2019 16:22:28

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 blush


Thread: ACME vs lead screw
17/04/2019 16:18:44

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
15/04/2019 19:45:34

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

Am I missing something or am I just "special" but my version of Draftsight is still fine even after having to re-download it about 2/3 months ago after a big PC crash ( total reload of everthing). No problems at all and no messagesasking for money.

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.


We are also investing in other technologies including an upcoming cloud-based version of DraftSight and much more. Therefore, we want to make you aware that DraftSight 2019 for Windows® is offered in paid versions only, and all free versions of DraftSight (2018 or earlier) will cease to run after 12/31/2019.

Thread: No 20 machine oil
09/04/2019 09:39:27

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
04/04/2019 19:04:50

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

...none of these differentiate between commercial production and one-off or personal projects....

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
02/04/2019 08:35:48
Posted by Hopper on 02/04/2019 07:58:09:

Why? Why cheapness of manufacture of course. Half the cost. Same price. Bingo.

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.


02/04/2019 07:42:34

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
01/04/2019 10:30:21

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

..You can always do the same for taps to tap down deep holes.


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
31/03/2019 17:21:44

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
30/03/2019 19:18:40

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
30/03/2019 09:00:50
Posted by Paul Lousick on 30/03/2019 08:28:42:

I'm not game to wash engine parts in the dishwasher for fear of the fallout but I do know that the detergent tablets are abrasive. They will blunten the sharp edge on kitchen knives. They are also corosive and ate away the aluminium rivets that held the handles on my quality brand chefs knives. Fortunately thay came with a lifetime waranty and were replaced.


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).


30/03/2019 07:55:24

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

According to another thread Draftsight won't be free for much longer, and already installed ones will die.

death of Draftsight

the other thread goes into other programs available

Can the moderators merge threads? It is as if two parallel conversations are taking place on the same subject.


Thread: Tap and Die
29/03/2019 10:35:19

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
29/03/2019 07:37:57

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:

LA30 [TAB] to angle box 20 [CLICK] on start point (I would like to be able to enter this, and probably can)

90 [CLICK] on end of previous line (it snapped automatically)

150 [CLICK] on end of previous line

210 [CLICK] on end of previous line

270 [CLICK] on end of previous line

330 [CLICK] on end of previous line then [ESC] to end command

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.


28/03/2019 14:27:32

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:

LA30 20 (I would like to be able to enter this, and probably can)

90 (it snapped automatically)





What surprised me was that I didn't at any point have to hit , and what pleased me was not having to type "@" or "<" (as in "@20<30" ). I wonder if there is any way to make each line spring from the end of the previous one (perhaps I should read the section on polylines?).

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
