Hi Guys

Im cutting out some Aluminium motor brackets from 6082 Aluminium on my Taig with a 8mm 4 flute Carbide End mill.

Should I be using lubricant? I have not bought a pump setup etc yet as...

Hi Guys

Just a question, I have a Sieg C3 Mini lathe with the standard 3-jaw chuck, i work mostly with aluminium. Now say I need to work on both ends, I get one end as I want it, take the piece...

Hiya

yes im looking at making one, ive made a few prototypes, I have a design that I believe will work butit uses a method I have not used before on a lathe, so it's taking a while

DJH

Ok where to start....

I bought my Taig from Peatol in the UK, I bought the manual Mill, and the cnc conversion kit (mounts) from them. I then had to put it all together.

Hiya

Sure, as far as the mill is concerned im very happy, I only have two complaints, the first is that the way covers are a pain as they get in the way, but are needed. And secondly if I had...

Hiya

Thats what ive been using, but I have been having problems getting the boards flat enough, I want to try it with an etching pen int he spindle, pcb-gcode removes the copper around the tracks,...

Hi Guys

Ive not had too much luck with making pcb's, I either can't get the board flat or can't find the right bit.

Im working on a spring loaded engraving tool, but it's taking a while.

Heya

Just an update, have been tidying up the workshop, has taken 3 days, so not got much done, ive made the new outer section, just gotta work on the inner now and give it a test, this one is...

I must admit, I do like the look of those AMA180v's, I was going to get it, but no-one had any for a few months, so I went with the C3 with DRO's and variable spindle speed + rpm display, plus there...

Hi Martin

I am in the UK, I have a Sieg C3 Lathe (7x14) from www.arceurotrade.co.uk, they are also on offer at the moment.

Im very impressed with it, they do offer to set it up for you before...

Hiya

Thats an interesting idea, I will try and get one and see what I can do with it.

with regard my version, I have a set of reamers now so I hope to spend some time making a new version

DJH

If your in the Uk like me, check out motion control products for steppers

DJH

Thanks for the advice guys

I have considered split pins, e-clips etc, all of which I may try if i can find the right sizes. as soon as I have found one that works well, i will be able to see how...

Just had my 4-jaw chuck, Tailstock Die holder and new cutters arrive so i can try and make the new and improved version :)

DJH

Ive used 8mm Endmills on Steel, Ali, Brass and wood on my Taig, but then I don't have the original spindle, so can't comment on how it would hold up, but the machine itself had no problems going...

Well first test results:

I loaded it up, lowered the Z axis until the tip touched the pcb, lowered a bit more to take up some slack, then jogged in a straight line, lowered some more and jogged...

well, it's the same principal as the ones sold by 2linc.com for a lot of money, once the correct spring is selected, although the force is not linear, it seems linear enough in that regardless of...

Yep thats it LeeWay

Ive found it near impossible to get pcb flat with various different methods, it only needs to be out by a little bit to mess it up.

DJH

Thanks

I most certainly did, it's still a little bit of a struggle and the line you align it with is a little bit thick, but it definatley helps, still not dead on but the end slides up fairly...

Hi Guys

Have a look at my first post in this thread:

It has a picture of my engraving tool prototype (needs improvement).

As I said im...

Hiya

I think the first questuion would need to be "how much are you looking to spend?"

Are you looking for a mill retrofit or a gantry type router design?

If you fancy making one possibly...

Ha ha thats wierd timing, ive just this very minute almost finished my prototype for a spring loaded engraving tool, it's going to need some refinement and I have no idea on what springs to use.

Hi Guys

Im having problems holding down pcb's

I have a Taig mill with a normal T-Slot bed. Now my problem is that I just cannot hold the pcb's flat enough. I spent ages getting it so that I...

Ok, just read that link, I see what you mean now, i did not understand how they work, and can see how useful they are, i will order one right away, and let you know how I get one.

Thanks, cheered...

Yes I also took into account the tool diamater, i am using 3.175mm tools in a 3.175mm collet, also double checked on my vernier calliper, so i just divide that by 2, aswell as the rod diamterer, then...

thanks oldman, how would that help with what I am doing though? I can see it's a very useful tool nontheless, Im trying to work down the length of the bar (baer laying on it's side) and not on the...
