Thread: Which is the most popular

Just a general q how do you get revenue from magzter?

if i read it all or just open the magazine

or just for it being available on the site to all?


31/03/2020 17:13:35

I’m not really sure Bandersnatch

theres always a way

I’m was an avid magazine buyer but storage was becoming a problem...i just couldn’t throw them away

anyway things got auto a head and i got rid of all

The late JS had all my classic motorbike mags in the last 6 months of his life..i hope they eased his illness

since discovering Readly and Magzter i can read away without disappearing under mountains of paper

Whilst the full archive isn’t on Magzter i can see issues back to jan 2015

I’ve never seen a memory backup battery in any VFD

you can generally set default settings by a parameter

but i would look at your pot wiring first

Ian P

the piston and wedge type are very similar the toolholders are the same

but the piston pushes the toolholders out against the dovetails

the wedge type pulls the holders in towards the block

19/03/2020 09:54:55

Another consideration is to do with price as well

how many tool holders do you expect to end up with

i bought the Chinese piston type first (300 size)was quite happy with it but always had niggling doubts about its ridigity and repeatability

so at great expense bought a wedge type from USA ( 300 size not common over here)

and happy with that

ive had a Dixon type which came with my lathe but toolholders so expensive so sold that

and dabbled with a multifix ( the best in my opinion) but holders very expensive so sold that 

But all told now i have 50 toolholders all 300 size with various tools attachments in them.

so i would base your needs on the cost of toolholders...

Thread: Desoldering how to?
10/03/2020 18:32:06

I saw a desolating iron on amazon

and it works a treat on some sample boards

it leaves fully open holes components come straight out and new ones go easily back in

And only £13

i wish I’d had it yesterday desoldering 20 leds

Thread: Led id
09/03/2020 15:54:23

Thanks for all help i have large stocks of leds but none like the ones fitted


But after a job i hate stripped out all 20 uv ones and soldered in 3mm white ones I’m in business with white light

5mm ones wouldn’t go in the shroud so i had to downsize

its off a mantis microscope so should make all the small jobs go better

vision engineering wanted an astronomical price for a white led board

09/03/2020 12:48:19

Thanks bill

they are in a to18 can but i dont seem to be able to find any white in that can

09/03/2020 12:11:46

Can anyone identify these leds and suggest a replacement?

these are uv for a microscope i want to replace with white light

they are in a metal can withthe lens poking out the top

the body measures 4.66 mm and the can has a tag on it

from under the rim of the can to the top of the lens is 7mm

I need 20

I was always under the impression that MPP’s were rather cheaper than the competition and looked down upon by the cognoscenti

having said that i suppose even £75 was a lot in the 50’s and 60’s

having said that I’m quite happy with my models that i own

certainly Basil Skinners book talks about the lack of funds at the factory for development

Certainly on my Colchester student the 21 t is the driver for 4 rows of threads and feeds

the 42 is for 1 row of faster feeds and lower tpi’s

this with a student with a gearbox on as the op’s

But as Micheal G said you can see an iridescence in the top....would you not see that with any other type of cutter?
