Another question of something that is hard to find answers for!
Spring tension!!!
I am aware a gauge can be bought to measure it.
Is it measured just for the back spring?!?!
How do you measure it?!?! from the armature bar? front spring?
can you measure the front spring tension?
and lastly, what are the 'ideal' tensions for liner? shader? and color packers?
obviously they would be subjective to the artists tastes, but there are surely 'starting points'.

I don't mean to shoot you down but the answer to this can be found in the members section and not in just any particular post but through tons of reading and expierimentation. sorry.

thanks steal25, i thought this was the case - i'm currently getting my paypal in order to check this out in the member's section!
i have a pretty good idea on what it is anyways! one of the advantages of doing a university course in physics ey! haha!

I understand the type of gauge you are talking about but I have never heard of anyone using a gauge to measure the ammount of pressure/tension on the springs. Using such a device seems like overkill to me. I think the gauge you are asking about refers to the thickness of the springs ie 18, 20 etc.

i think it is spaulding rodgers that sells a spring tension gauge.

steal25 you got it again! i did mean tool. buzzbrush - the main reason i'd want a tool like this is so i can have a starting point, which after some experience would allow me to feel the correct tension accurately. i presume though, you have just developed a feel anyway, after experience.

.018-.020 of an inch is how the springs are measured..

Your absolutly right when refering to thicknesses

i'd like to add that i posted that link just to show one of these tension gauges in action and how to use them. i don't think it's the bible of tension theory, though. I've never used one of these, but may get one just to try, surely it can help someway. as stated, yes i also think the best way to get the exact tension is experience.

For disciples of extreme machine theory Danny Fowler is your man,his gauge is really the only one worth having....if you go for that kind of thing.I dont.

Good link for demonstration Fabs,....agree that experience is the only real way

Isn't using a EMS or Multimeter to measure Duty % to get the same result..... the same thing?

no it's not the same. the duty meter will tell you the % but not tension ammount. obviouly you can use it to achieve proper tension but they are different tools.

Spring tension can be measured using a digital hanging scale,such as used in fishing,but they only seem to weigh in 20gram increments....but thats most likely more accurate than most of the bendy bar type devices.One of these things will set you back 10 bucks,a fiver british on the 'bay....

....seems like a lot of fuss about nothing to me.Ive seen machines that by the numbers and measurements shouldnt do a thing that push ink smooth as butter,as Im sure most of you have.

This is a situation comparable to most specialist interests....when you start out "experts" and vendors will tell you that you need everything under the sun to be able to get results.Some years down the line you realise that you have pared away all the gadgets and are working with the bare minimum of good solid kit that you thoroughly understand.Since we already have fishing mentioned its a useful analogy.When you start out fly fishing you are told you need different rods and reels and lines and clothes for each seperate eventuality....you end up so weighed down by kit you can hardly move.Some years down the way you have one,maybe two favorite rods ans reels and a tin of flies.All the rest is sitting looking pretty but dusty in the shed.You catch more and better fish and have a much better time.

Same kinda thing,seems to me.I seem to have blathered on somewhat.Nothing new THERE then. :blink: :)
