How’s the progress? Does it work?

You have a tapered gob which acts as a seal. I would try it first without the channel and see if oil gets where it should. I am pretty sure it will

At some point I bought some very low profile compression fittings for nylon tubing. Ordered them from china (off-course)
Worked really well and had a small form-factor. Only downside was the...
Here you go...

But as stated before, with a tapered gib machine this is not needed. The...
You can check my Optimum MH25V thread. I posted there pictures of the oiling setup and you can see what I mean

On my setup the oil fitting go on the side of the casting and the oil hole goes straight to the gib. A perpendicular hole was drilled so oil can get to the way surface.
In order to achieve oil...
Do you have tapered gibs? If so then you should be fine.
With parallel gibs I had to make a 0.4mm metering hole on the gib side to ensure that both the gib and the dovetail received oil.
For...
SMC push fittings:
M6 thread: KQ2L04-M6A
M5 thread: KQ2VS04-M5A
Needle valves are AS1201F-M5-04A
All fittings take 4mm OD tubing.
The part numbers are for the metric version, but SMC...
As for fittings I used the white plastic ones from SMC with 4mm OD nylon tubing. Good quality and available in several thread styles.
Mandatory is a good needle valve manifold. The china ones are...
Any kind of cutter will do. Don’t overthink it.
The dovetail has a 60 degree angle so the oil channel will not look that pretty. Just use any cutter you have on hand and calculate the depth of cut...
Looks good

Dovetail channels can only be made straight. I used a slitting saw for this operation.
And the gibs are drilled through where the oil is squirted.
I have also cut a channel on the gib face. No...
One diagonal straight is enough. The Z shape is just for design.
The idea with the diagonal cut is to spread the wear over the whole way width. Some say that a straight cut (like mine [emoji2958])...
Hi,
If I remember correctly 1mm.
Made them with a 3mm ball endmill.
Depth is not really critical. The oil pump puts enough pressure to get the oil where it needs to go.
But if I were to...
Hi diyXpert,
The corona crisis delayed my plans for a while. But the Paulimot is still on top of my list.

BF20 is the same as G0704 but with some castings differences.
But you would want the BF20L version that has longer X travel.
Conversion wise there are many CNC kits available. In europe there...
Hello,
Taig mill is tiny. Save some more money and get a BF20. You will be way more happy

Hello,
I had an IKEA LED lamp lying around and I decided to make a lamp for my Optimum MH25 mill.
While others have also used this lamp for their machines, I decided to take a slightly...
Some weeks have passed since I started using the machine. In the mean time first parts have been produced and I would like to give some conclusions to this review.
I made a nice pair of vise...
Had some trouble with the Z axis screw. The bearing block was not aligned with the Z nut. It was 3mm off and was binding at the top. I elongated a few mm the bearing block screw holes and now the Z...
Hello,
I made a lot of progress with the mill.
I finalized machining the gibs. Added dimples on the back side to accomodate ball ended adjustment setscrews. This makes gib adjustment super...
Made more progress with the vise.
Bolted on the table and measured how parallel the ways are to the table. Result: 5 micron difference (0.0002") over 100mm distance.
When fully tightened both...
Hello,
Just received a new 4" size machine vise.
It is a Kurt lock-down clone made in Taiwan and sold under the brand Knuth.
Model number is PMZ100:...
Thank you all for your advise. I went the 1um sensors route.
I ordered them from a uk based supllier. The sensors are made by some company out of india: electronicaems. They seem to work very well...
Option 1: Delta AC servo controllers have both motor encoder input and table linear encoder input. They have encoder output signal + position error alarm signal. Dual loop can be closed at the servo...
Partially I agree with your statements.
Adding a control loop might add instability to the system in the form of jitter or faults, depending on the setup. But only in case the control loop is set...
Hello,
I am about to purchase linear encoders for the mill.
They will be connected to a DRO for now, but in the (not so distant) future the mill will ve converted to CNC and the linear encoders...
The low resolution you are getting is because of the magnetic tape.
The reading head might be capable of 5 microns, in the end it is just a magnetic pick-up coil. But the tape must also be...
Something is very strange with many of these china products.
In the Optimum documentation from my milling machine the indicated DRO5 sensor is the MS100 from SIKO.
