ed lights for mill,,
stirling lad:
''Sackboy'' So thats who he is!...I'd no idea, :scratch: he just appeared in my workshop one day looking a bit annoyed about something so i though it best to just let him hang around and calm down... :med:
...M...
shipto:
He is from littlebigplanet on the playstation.
stirling lad:
ahh, I thought he was something from a Tim Burton film,like nightmare before Christmas or something..
Col, I have'nt done a mod thread on the gas strut but there's a lot of them out there,, find out how much your mills head weighs then check ebay or wherever for a strut that'll lift that weight,, strut power is measured in Newtons,(N).. ten N = 1Lb ..my mills head weighs around 15 Lb so i need to change my strut to one with a rating of 150N or maybe slightly more to give it a natural uplifting motion ...The over-all (extended) length of the strut for my mill is 20", I've no Idea what length it needs to be for your mill. Is'nt there a forum for that mill type owners?. The strut I have on it is way to strong at 300N and rolls the head back up when I take the lock off when its on the drill press handwheel. Its good when its on fine feed, it makes lifting the cutter from the job very easy using the fine feed knob, but I think I need to change it soon as it'll wear parts away very quickly..I have another strut ready to go on thats rated at 150N so i'll let you know how it goes...

A mass of 1kg exerts a downward force of approximately 10N
Force = mass x acceleration. In this case the acceleration is that due to gravity, i.e. 9,81 m/s^2.
So 1kg mass x 9,81 m/s^2 = 9,81N ~ approximately 10N.
If you equate 1lb to 10N you will be a factor of about 2,2 in error (because there are 2,2lb in a kg)
Strictly a lb is a mass and can't be compared to a Newton, which is a unit of force. The unit of force in the imperial system is the Poundal. The Poundal is the force that will accelerate a mass of 1lb at 1 ft/s^2 (and it's a bitch to work in these fathom, firkin, fortnight units, the SI system is much simpler, and if you don't believe me try working in imperial slugs. The slug was/is an alternative unit of mass to the lb; it equated to approx 32lb because g is 32 ft/s^2. I don't recommend working in imperial slug units as it has been known to make peoples' heads explode).
Now I have mentioned slugs I'm off to find the aspirins.

Thanks Eric, Mike , Pete
When I dismantled my mill to fit the DRO scales I had the foresight to weigh the head - 27kgs. I will look for a strut with a power around 27 Newtons.
Another project to add to the list which is getting longer and longer.
