POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[GoceKU]

I guess you could roll those up or squeeze them, like a toothpaste tube, to get the last drop out :~)
OTOH, you'd need another jug to put the drain oil in for recycling - They don't look refillable.

With the amount of west oil i go thru i need to get a 55 gallon drum, in the past i've used those 60L drums but they don't seal and are hard to move, no handles.

I set up a deluxe RPC to power the big lathe. 20 hp to handle the infamous Weg motor inrush. I ran a breaker in the enclosure this time (my 5 hp I used a second panel, don't know why), an aux twist lock receptacle in case the 5 hp goes down and I need to run the mill or another piece of yet to be determined 3-phase equipment (ahem, surface grinder, pro T&C grinder on the wish list). I installed V-A meters to keep an eye on things, volts from between the three phases and amps from the output legs. I hope the response time is fast enough on these to see transient startup loads. I might have to follow @rabler 's footsteps if I need more. I also run european outlets where I can because I have a bunch of EU tools from my life in Germany, like the nice Karcher pressure washer and Karcher shop vac that is dedicated to chips, among others that don't mind running at 60 hz. The EU outlets in the shop circumvent code by being decoupled by the RPC appliance. The outlets on the other end of the shop are on a pigtail adapter I made, not hard wired to the breaker either. Not that it makes much difference, these are 10-amp receptacles only. After my coffee this morning, I will will wire the lathe panel and have my moment of truth.

Made some small adjustable screw jacks to be used on my mill table, I recently had some drilling projects that extended a bit beyond my vise and got tired of stuffing wood blocks underneath for support. Design I came up with uses a 1"-14 thread on the jack and the extension range is around 1.4", that section body then can screw into a separate riser which adds another 1.25" height, so in total I have 2.6" height range. I happened to have a 1"-14 tap that I used to make a female fitment ring and a male counterpart mandrel to setup my threading parameters and cut all the threads on the lathe to basically a zero clearance shoulder for internal and external threads.

The upper and lower section screw together and either section can be attached to the T slot in the mill table, as both sections have 1/2"-13 female thread on the bottom and there is a short 0.1" alignment shoulder as a guide for alignment between the lower and upper sections. The screw jack and locking ring I used 1144 stress proof that I had on hand, and the upper and lower body are 2.125" CR 4140.

Threading, pretty much maxed out my lay-down threading tooling as to thread depth as well as length of the internal thread. External and internal threading was done at ~300 RPM which gives a very clean cut, the 1144 was a dream to machine compared to the 4140.

GoceKU - You post here a lot, so maybe you can answer a question for me -
On another forum, there was a thread about tire sizes, and a poster (from Germany I think) said that tire sizes in Europe were locked in to the size tires on your car when it was first registered - I don't know if this was just for Germany, or all of Europe.

In other words, you couldn't legally change the size of your tires to something larger or smaller than was stated on the car's registration.
He said that you could apply for a certificate from the department of transportation (or whatever it's called there) to get a different size listed on the registration, but it was limited to the manufacturers recommended sizes - I'm guessing this is from a safety standpoint ?

I thought this was an interesting difference in vehicle laws -
As you know, here in the US, anything goes with tire sizes, sometimes resulting in some pretty unstable-looking combinations for sure.
So, is this the law in Europe ?

 

[pontiac428]

That is the law in Germany for certain. It's about liability, something that Americans don't respect because it encroaches on freedom. The freedom to do stupid stuff with wheel and tire combinations that change the way the vehicle responds to changes in speed and direction. The amount of self-responsibility that is expected out of an average European citizen would boggle the mind of the typical yankee. If it touches a public road, everything from tires to ratchet straps to antenna toppers has to be Tuev certified. Hmm, no number pad means no umlauts. Any incident caused by willful violations are penalized. Not with jail time, there they just take your money. That hurts plenty, and is a powerful deterrent.

Edit:
Also, every deviation from stock has to be added to your registration. My Nardi steering wheel was on mine. Each modification is similar in cost to an ATF "tax stamp" for NFA toys. Sometimes, the variance permit costs more than the modification does.

Double edit:
And if you think it's a one-time fee, you will be surprised at renewal. Modifying vehicles becomes a rich man's game very quickly.

How do they perform in your opinion? What RPM did you run it at. O and DOC?

I was impressed with them. Slow RPM. Turned the knobs by feel, but the cuts were light. Probably .010" DOC. Being nervous about it, made sure it was always cutting while in contact. Honestly, it was extremely smooth cutting.

The chip was amazing. It looked like steel wool coming off there, but if you squeezed the bundle it just crumbled between the fingers.

 

[GoceKU]

The tire size is written in the car's papers, car's log book i can take a picture to show you how it looks. In germany like all the laws they are very heavily enforced if you get checked you'll get a fine with different size tires, rims are not monitored alloy or steel. In my country and many neighbouring countries like Bulgaria, Serbia, Albania, Greece there are same laws but are not enforced. Here we have the best cure for large rims and low profile tires (potholes) everyone here runs smaller rims with 55-75 profile tires. You can see how many times those rims are welded, to brake a wheel that is bigger then 16" is a real concern.

A quickie from Saturday.



The 8x1x1 Norton grinding wheel was wobbling on the shaft of my cheaptastic Delta bench grinder. I thought the plastic bushings might be to blame, so I ran this up. But it didn’t completely solve the problem, which is that the dished washers have too much of a radius and too much slop, and don’t seat reliably square in the shaft. Making this bushing tight enough to prevent that might risk the wheel if the bushing expands with heat.

So I’m going to make new washers. I may make the inside washer integral with a bushing like this.
