Best protective oil / coating for chucks, tools, etc.

[BanjoDude]

Did you pick up way oil for the ways...? don't put the T9 or fluid film on the ways.. its for exposed metal parts that don't slide against an opposing part... Hopefully you have the manual or can download it, there are a lot of rotating items like hand wheels, tailstock quill, lead screw and what not that need to be regularly maintained that can use machine or gear oil, but your manual may specify...

Also check that your way wipers are in decent condition, small metal debris can get lodged between your carriage and ways and cause damage, take some way oil and lightly soak news paper, clean shop towel or like and lay it over your ways when not in use to keep dirt, sand & dust off.

Take a look at this thread, talks a little about your lathe --> Emco Compact 8

Its a great little lathe to start on and kind of like most 9"x19" & 9"x20" on the market today. a word of wisdom - never store the chuck key on the chuck ever. find it a proper home away from the chuck.

Use HSS tooling if you can... not Carbide unless you have no other choice, pretty sure your lathe uses a belts get a spare. you can search google for 9"x20" Mini Lathe Mods and may find something of use.

Good luck with your lathe Sir...

Thank you! I do have way oil and am using that on the ways. I just used t9 on the chuck outer surfaces to help protect from rust. I like the suggestion to coat paper and keep on the ways when not in use.

Curious about the suggestion to avoid carbide tooling. I just bought a set today. Wish I had seen this sooner. Would you mind explaining? Hope you had a nice 4th!

Carbide tooling will work fine, I used it with my 9X20 lathe, lol I went thru a lot of bucks trying to use the brazed carbide stuff from Harbor Freight. They were chipping left and right... while I was Learning I had a hard time trying to take really light cuts, trying to sneak up on the part just to take a tiny fraction off, I found that I was deflecting the part before the tool would start cutting from to much Stick-Out then grab the tip and pull it under snapping the carbide tips off... Really Sharp HSS cutting tools seemed take lighter cuts allowing me to keep my tool farther away from the chuck while learning...

Its just a learning process, You can use carbide tooling for sure, Spend a little extra and get tooling that uses Inserts, that way you just replace the insert as you damage them... You can buy HSS tooling from Little machine shop and other places online with pre determined shapes that you just keep sharpening with a stone as they dull, and save a lot of money while your learning.

Some of my favorite Youtuber people below, make an entire series of useful project videos from just starting out in machining to complicated tools you make yourself, all very detailed and fun to watch....

Watch This old Tony - Great Carbide tooling video, Link ---> Carbide Tooling.
Watch Blondihacks - Great HSS tooling video, Link---> HSS tooling.

Also seriously consider Getting or Making a cover for your lathe, oil attracts dust like crazy.

Go have some fun, Mike.

I learned from Stefan Gotteswinter that it’s actually okay to hone a carbide insert to have a sharp edge. A diamond hone is required, of course, and it works better with uncoated inserts. Manual lathes, also—honing will mess up the indexing when replacing an insert in a CNC tool.

The aluminum-specific inserts arrive MUCH sharper than the steel ones. In a production environment, a tiny bit of rounding on the carbide edge makes it more durable.. it just drives US crazy
