Thank you Neill. I just downloaded the dictionary and it will be very useful to me.

I have been following Clickspring for a few years now. Unfortunately , he seems to have slowed down in his posting.

Agree that is amazing.

Thread: Query using Turbo Basic
03/03/2020 10:11:37

Not sure it helps, but I think if you separate items within a PRINT statement with a semicolon they are printed on the same line. But each separate PRINT statement will add a cr/nl sequence .. You need to use PRINT a;b to get both a and b on the same line.

Could you use PRINT USING or use TAB or LOCATE ?

Finally, it might depend on the output device. Are you displaying the information or printing to a printer.

Sorry but that is about all I can remember from Turbo BASIC days. (It might also vary depending on the version of Turbo BASIC)

Thread: Metric V Imperial Measurement
09/02/2020 17:26:22

.The Americans actually use two different definitions of foot, , the customary foot and the US survey foot. But both units are defined in relation to SI units. There is no independent, primary, American or Imperial standard. All are simply defined as so many metres, etc.

For most of us, dealing in major divisions or multiples of the metre is easier. But I appreciate some people like to work in multiples ( or divisions) of 0.0254metres.

Wouldn't it be awesome if we went back to imperial. Stuff the rest of the world. Rule BRITANNIA. Britannia rules the waves.

Steve.

I am always open to be converted.

Can you tell me what advantages using the Imperial measurement system would afford me?

Thread: 1/4" BSF v 1/4" CEI

Keith, have you tried Dragonfly motorcycles. They have bought up some old triumph and BSA stock and also supply spares for Triumph and BSA. Although they might not have the allen heads you want

Steven at AMC Classic spares can supply 1/4 BSC(26TPI) nuts and screws/bolts

I am constantly working on both BSF and BSC and the 1/4 have the same pitch but are still not a good fit. Steven will supply all the nuts you need and quality is excellent. ( I have no connection other than as a customer. AJSMathless club will also supply these but you will need to become a member)

Hooper wrote "Most old Brit bikes I remember working on used the coarser BSW on case screws going into aluminium."

The motorcycle must have been very old. I have never seen the courser Whitworth thread in any motorcycle I have owned. AMC studs are BSF into the alloy and BSC for nut. However I notice similar studs on Velocettes are BSF along the full length.

BSA (and presumably Triumph) switched to UNC threads late 60s early seventies when their main market was USA.. They seemed to have changed gradually as i have a 1969 A65 which has both.

Thread: Creality 3D For Christmas - Impressions so Far
02/02/2020 19:13:07

The filaments I bought were from Flashforge. I just noticed they felt harder than I expected but I have had no real problems. Like you, I will experiment a bit first before I try any expensive filaments. I am just looking at YouTube for instructions! So far it is all working okay and it is definitely an interesting technology.

02/02/2020 14:27:21

Hi, just new to 3D printing too. I have used the PLA filament that came with the printer, Ender 3, but I find it a little brittle. I wonder if anyone has any experience of using PLA-Plus , which is apparently less brittle?

i just tried RMA's method. It did not work. It is still demanding a new black ink cartridge.

.

Will it print.

I have the same error message on a Canon printer, but I have the option of printing anyway . Can you just attempt a print anyway or does the printer stop you doing that?

Thread: Why does everyone disagree with you
27/01/2020 09:48:21

Steve, I read your post which I think gave rise to this topic and I understand why you are a little put out at some of the responses.

For what it is worth, I still think they are in the minority here. I for one enjoyed your post

You must be a young'un Steve, as a child my chips were 3d (proper money) a bag!

Mine were wrapped in newspaper and we ate them on the way home on a single decker #108 bus from Bow to Homerton.

Thread: Big HELLO from Dublin.

In much the same position as yourself, I have a small lathe for making items for my motorcycle too. Situated in Galway so I too am familiar with both the cost and scarcity of machines and tools

Best of luck with the A10, what year?

I have never made a 15mm/1/2” copper coupling with a “special’ connector, but I do know that 1/2” is 12.7mm, not 15😉. They are close enough, for a solder joint, to be compatible.

I believe the 15mm pipe is 15mm outside diameter. The 1/2" pipe (1/2" inside diameter ) is 14.7mm outside diameter. So even less difference

It probably depends on whose word definition you believe

“When I use a word,’ Humpty Dumpty said in rather a scornful tone, ‘it means just what I choose it to mean — neither more nor less.’

’The question is,’ said Alice, ‘whether you can make words mean so many different things.’

’The question is,’
said Humpty Dumpty, ‘which is to be master — that’s all.”

Thread: Honda Brake Cable

Is the outer cable fitted correctly into the adjuster on the handlebar lever?

It is hard to tell , but in the photo it seems that it might be sitting proud of the adjuster ring.

I think I'm getting it now. "Swing over bed" is that distance between the headstock spindle centre and lathe bed. It's 180mm for the lathe I quoted a description for.

Edited By Richard Rogalewski on 18/01/2020 21:45:14

I think 'swing over bed' is the largest diameter of material it can turn. The distance from the ' headstock spindle centre and lathe bed' would be half this size, .e. 90mm

Thread: VFD Question
17/01/2020 09:50:11
Posted by Mike Poole on 16/01/2020 20:16:24:

I am wondering if you are muddling the base frequency which should be a motor parameter with the output frequency for the desired speed. Setting the desired output frequency to 50Hz should give the speeds on the plate. The base frequency is information used by the inverter to model the voltage/ frequency curve for the output to the motor.

Mike

It is quite possible I am muddling things up.

The actual settings, On the Bosch Rexroth VFD, refer to max. frequency and upper frequency, both set to 31.5 Hz

(= 50 x 240/380) (it should be 30,3 Hz (= 50 x 230/380). This keeps the voltage/frequency ratio constant which I gather from all the answers here is not really necessary.

Thanks

  I eventually fitted the digital tachometer and measured the speeds on the mill in comparison to the speeds given on the gearbox plate for low and high speed . The VFD was set with voltage set at 230V and base frequency at 31.5Hz
Low Speed High Speed measured Speed
95                    190                       128
150                  300                       205
235                  475                       322
375                  750                       389
600                1200                       637
950                1900                     1040
It would seem that the motor is wired for high speed and is achieving over 50% of the expected speed.
