Anyone who comes up with the idea of selling a little illustrated handbook for all these tips is going to save a lot of these type of enquiries to say the least.

The type of abuse that normally does in all these tips is interrupted cuts or parting off centre. The tip in itself seems to be able to withstand a lot of wear.

I would imagine that someone totally unfamiliar with turning would be left very frustrated by using a 4 jaw independent to begin with. You're kinda being thrown in at the deep end there. If you want a piece of round material chucked reasonably over a range of sizes then you'll be very satisfied with a 3 jaw and more importantly, actually turning rather than setting up. Get the 4 jaw once you can deal with turning and using a 3 jaw.

The technique is to clamp the knurls whilst it's running to reduce the starting load forces, then run the knurls forward and slowly run them back up the diameter and you should get a lovely looking knurl.

They are made using a very specialized type of material, it's designed to suffer as little expansion/contraction as possible under temperature extremes.

Agreed, the fact most lathes today are sold primarily with a 3-jaw should give that fact away. You'd be driven positively insane if you were to dial in each and every turning job on a 4 jaw.

+1 Fantastic on metals too.

I'm sure I've seen this displayed elsewhere, the "mechanical man" statues

I seriously doubt all hand tools!

try running the tap down again?

Though he could just spend the money himself to feed them.. it's not like he couldn't if he did want to.

People can have a fairer society, but unfortunately they're going to have to find the will to choose it, the communists tried to force it on people and it led to disaster, and eventually corruption.

Personally I don't believe in enormous amounts of (though some justified) government intervention.

Yep, wouldn't be the first time a big corporation has defended their actions in the name of profit and cover up evidence of harm to life.

Theres also some bowden tubing sold here if you do consider that head..

Or this one comes with the "hot end" head as well as a tube.

PS, might wanna check this out Neil, if the extruder feed is giving you trouble;

This is an upgraded version of the stepper extruder head used on the prusa I3, and although it is intended for the one I bought, they claim it can work with most reprap machines.

I paraphrase in sintrons own words;

"The extruder is the most important part of a 3d printer, and also the most difficult to calibrate, we have made necessary design to prevent "jammed" problem. I cant emphasize how important this is and other sellers don't have this and would cause many problems....

The MK8 extruder is open source universal suitable for most reprap and DIY long distance feeding filament 3D printers"

Yeah I understand they're a small company and probably never anticipated so many people wanting this beefier version of the I3. I'll look on it as a means of adding diversity to our printer users!

That's unfortunate about the spooling inconsistency. Not really experienced in this field yet but could it be a temperature stability issue? The more heat might help the gooey plastic to lubricate it's way through the tubes.

I know that with injection moulded thermo-plastics which are a whole different animal but with those, when recycling nylon, you need a lot of heat and pressure to get it to shift.

Warco have always been very good to me, so I appreciate seeing their support carried through on here by other users.

Thanks Ketan.

Good to know, thanks!

I have the same trouble with aluminium not taking the sharpie ink well after a judicious amount of WD40.

I really liked the look of the prusa I3 and especially after having seen their recommendation in the magazine, I think this is having a knock-on effect, because I can't get hold of one.

I asked the guy who runs the site when a new one would be relisted and he said Wednesday evening, I didn't get paid till Thursday morning and it appeared as though he hadn't done it,

so I asked him again on Friday and he replied that they get sold so quickly you have to be within minutes of the listing to have a chance. So he said the only thing I could do would be to wait until next week to get another chance at bidding for one.

I politely refused so unfortunately I'm having to look at other models simply because of this supply problem.

It might be a bit of a moan but it just goes to show it doesn't matter how good the product is if I cant get hold of it!

In the end I've bought a sintron kit, so I guess i'll see what this is like and see it as a chance to review a different model.

Sounds like setting yourself up for a failure. Without an "eyes on the ground" system you're liable to hacking I suppose.

Michael W

Indeed, you have the opposite problem to Mr Tinsley!

I can't believe this, within the same week, two posters have confused engineers blue for different purposes!

The stuff you want is layout ink, not the marking paste, that's used to find contact points on metal and scraping.

You can get it in a bottle or spray. Failing that a whiteboard marker will do for most jobs.

Don't throw it out though, it's still useful! Just not for what you want
