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

[great white]

Finished up the mount for my recently aquired radius turning attachment:





nothing fancy, just going for functional.

Today i worked on the bushings for VW fuel injectors. They did happen to be either case hardened or thru-hardened. Just a little to hard for the little lathe so i had to go to the South Bend. I think they came out good and should make the customer happy. Next time i will hopefully have the surface grinder running to do this job if it comes back. I do need to find a set of belt drive pulleys for my South Bend. I would really like to have the 2-step pulley from the motor to the countershaft for more speed. Could have really used the higher gear for it.

 

[Just for fun]

So what do they do, let more fuel in?

I think so. It is a stop for the nozzle needle. Im not very familiar with this type of stuff. The bushing is number 11.

The project of the day was to install a EV charging station on the big garage. The big garage is single phase 220v but it still a leaf can charge at ist high 6Kw rate. I had to run soft cable from the fuse box to the charger just because of the spring clamp connection point at the charger, i did run them thru flex conduit. And installed 32A breaker on a separate leg for the charger. The charger was New so the instructions and mounting hardware made mounting and setting it up easy.

Looks like the intention is to put more pressure on the poppet spring, which means it will pop at a higher pressure. Finer atomization, a bit more quantity per given time interval...

So I was able to finish the turning of the rollers, a file was used to "polish" the surface it came out awesome, 6061 aluminum.





My cheap import collet gouged the hell out of the shafts every time I inserted or removed the shaft.


The rollers assemblies are mounted on bearings (two bolt flange type) between two 3/8" plates. I used roll pins to temporarily fasten the two plates together and milled all the necessary holes.




I wish I could share images of the entire assembly , but I been sworn to secrecy.

Wow, that's less than a 100 foot air hose. I didn't know pex al pex existed. I have watched pressure tests of hot water in pex, and it exceeded the specs nicely. I would feel comfortable with pex w/o the AL, but at 70 for 300 feet, (are you sure you didn't typo?) it seems like a no brainer

I see Amazon's price has gone up with oil prices since I did the project. But you can find ebay sellers that are still similar:

1/2"-300' feet Orange Pex-al-pex tubing for heating, plumbing 689807255112 | eBay

PEX ALUMINUM PEX. 1/2" PEX AL PEX tubing is commonly used for installing outdoor wood furnaces, solar systems, in floor applications and plumbing uses. PEX AL PEX is a tubing which has a layer of aluminum in it to prevent oxygen penetration.

I know some sellers sell air kits that are pressure rated pex for piping air, but this was a way cheaper route.

OK, not in my shop, but in the middle of nowhere. I know a guy, who popped a hole in his oil pan. He found out after trying to start the car and the oil light came on. So, to avoid an off road towing fee, I did a quick patch job.

Cleaned everything (brake clean) around the damage really well, scraped/filed everything clean. Cut and formed some 1/32" aluminum to cover the damage and then some. Stuck that in the middle of some aluminum tape, and applied a very liberal coating of JB on the aluminum patch. One last good wipe down with brake clean, and stuck the patch in place.

The theory was the aluminum tape would hold the patch and JB in place while the JB cured. It also applied just a little hydraulic pressure to the JB, to prevent any seeping oil form displacing the JB and making a leak. After 8 hours it was holding oil. I'll find out later if he made it home or not...

I told him to stick a big patch of duck tape over it all before he brings it to the shop to have a new oil pan put on it. With any luck the 'duck tape' patch will make it on 'Just rolled in' on youtube! lol.

wow, nice fix! Did he hit something on the road?
