On an ER 40 setup you will max out at roughly 26mm.

With a 4 jaw independent chuck you can clock the part in concentrically using a dial indicator.

With a 3 jaw if you take out a machined part...

That is a bargain.

I have seen those collets sell for $50 a piece on fleabay.

With 5C collets for quick release I was actually referring to the lever operated functions to be able to insert or remove the stock.

There is still a threaded portion holding the collet in place...

That was a long time ago but if you search for CNC MACH3 USB motion control boards on AliExpress or ebay you’ll find them.

The board came with a mini CD that had a dll file that had to be copied...

I had Mach3 running on my 64bit windows laptop for over 8 years until I sold the cnc router. My card had a USB port.

LPT port aka parallel port (commonly used with printers back in the day) is the...

I have never heard of an MT4.5 before. I never knew such a thing existed. :)

I have given 5C a few thoughts over the years (mainly after watching American Y'tubers talking about them) but realized...

I doubt it will be available for too long. It’s a dynamic market place.

Contact the seller first and ask if he can hold it for you pending payment. (Chances are it’s already sold or someone is...

You mean 64 bit OS for your PC? What’s the previous CNC software you were using? Mach3 or LinuxCNC? Was it using an older LPT port or USB port

I’m surprised the mill was converted to CNC without...

Disclaimer: I have never seen a Hyco drill press in real life and the various angles your photos do not show the parts very clearly.

This is awesome.

I ran the $9.11 price from 1970 through an online inflation calculator and that's worth about $125 in todays money. No far off from what I paid for it, $100.

The S7’s were capable of higher RPM but the older ML7’s with white metal bearings only topped out at about 1000 RPM.

I will not be surprised if the older Hercus 9’s were not designed to run too...

I believe that is the type that takes a grease cartridge which is why it has a spring loaded mechanism on the cap.

Another thing you will want to ensure is that the nozzle on the gun matches the...

You will need a pom pom oiler which looks like a grease gun but is meant to pump oil into zerk fittings.

The cheapest I could find locally via ebay a few years ago was a Pressol oil gun.

I’m rusty on the terminology and without any reference used the word “active element” however I was referring to the length of the resonating elements of a yaggi antenna.

The active and passive...

Did you take into consideration the length of the active element? The length will depend on the frequency of the transmission wave.

Usually the active element is adjusted using a VNA device. But...

Didn’t get much traction on the Aussie Hobby Machinist fakebook group?

I am surprised the toolmaker spent so much time modifying and rebadging all those machines with his
BAKAHAG mark.

That EMCO FB2 clone looks fairly different from a regular FB2.

Not a tool but useful for tool storage.

I have seen them but most in a fairly beaten up condition.

Fakebook listed a Rota chest of drawers or parts drawer as I like to call it on my...

Just be careful with random CAD designs from thingiverse. Try and focus on designs with several likes and read the comments for feedback.

Are you affiliated with the seller? You seem to not want to post the cheaper $500 option that requires a little elbow grease.

Paying someone to make adapters is always going to be costly.

Some of these battery slotting mechanisms have awkward shapes/slots and a lot of measurements along with draft/prototyping prints...

Timbecon has these on Easter sale and I decided to pull the trigger based on Steve’s recommendations.

I think there are specific calculations for dimensions of the crown section of a flat belt pulley in the Machinery’s handbook.

Elasticity of the belt and width of the pulley is probably a factor...

The new batteries are fairly advanced and you will be shocked if you watch a teardown video of one.

On the topic of replacing the cells, I have had the most success buying Lion cells from vape...

Some of the new packs have very special chemistry for optimal tool performance and capacity.

And usually if the batteries are degraded to that point then the BMS is probably locked. This is where...

Yes, it can be designed and 3d printed. The terminals can be glued into the printed part and the wires or connections can be concealed inside the adapter.

Walk away from this idea.

This subject has been bashed to death online several times. What they are selling you is like a 3d printer with a spindle motor or a laser mounted to it.

If you work...

No point tearing them down as there is less than a 50-50 chance you can improve them and why waste time on cheap bearings as life is too short.

I prefer buying bearings from a walk in local store...

Welcome aboard the MWF.

No issues I can think of with the motor in the link.

These are often cheaper on AliExpress.

Last time I picked up a wiper motor at the car wreckers and was $10 from memory. But I was also buying other bits for a friend’s car so it was all bundled in.

The knob is not a big issue as I can...

Champion. You actually dove right into it.

I have been lazy to open up my wallet to butcher a new appliance and have been on the lookout for something 2nd hand.

There has to be a chinesium alternative.

Try and take an un-distorted photo and try a google image search.

I converted a 220v halogen bulb gooseneck to 12v LED.

I am more interested knowing what you are selling by the gram?

Opal?

Axminster has been in the business for a fairly long time and I have been visiting their website for over a decade now. They are safe to deal with in that they are a legit business.

There was a Sieg X2 (rebranded as a Paramount mill) for $50 a few days ago in NSW but I didn’t post it here because Kryn cursed those mills saying anyone that owns one risks a speeding ticket...

So in my mind the question is why is 200 RPM the baseline across the hand scraping forum posts I read and that's when everyone tries to brag about their AccuFinish running at 200 RPM.

If you scroll to one of my first posts in the thread, I mentioned 1200 RPM. I meant to say that this was the RPM at the lowest speed setting.

The Ozito manual only states the maximum RPM as 4000....

That is a Chinese made universal mill, probably a clone of a Russian mill you are referring to.
