Looks great Naiveambition. I have rust blued using the same procedure but I used my own mix of chemicals. I have wanted to try the Laurel Mountain product but at the time I had no income so I made my own solution. I used the following Solution: - 2 oz 3% hydrogen peroxide - 1/4 tsp white...

Thank you for the link. This is awesome! So much info on the SIEG SC4 !!! Great find! Of course I did the google translate and spent about 3 hours the other day reading through the threads. Lots of great ideas like the switch on the ways to shut down the lathe. I just removed the chuck...

Is it a copy of the Vertex ? Did you find that the worm has a few spots where it binds with the wheel ?

Do yu have a link ?

I’m sorry, what 152 pages of Sieg SC4 information? Maybe I do not see the link Robin Renzetti on youtube has started a series of videos (well one video so far) on fixing and improving the Grizzly tool and cutter grinder (Deckel clone). I’d Love to get one of these

I have this very same RT. Its almost a copy of the Vertex except there is no thrust bearing in the base of the casting for the table and the table fastens to the spindle slightly different. I added a thrust bearing from a chevrolet steering column and disassembled the entire unit and cleaned...

I just added 3 additional gib screws to my SC4 lathe compound to make a total of 7 gibs screws. I also added 2 thrust bearings to my modified leadscrew housing. Its not all finished yet. I have to trim the gib screws and I am not sure if I want to put a point on the end or a dog-point. I...

Excellent idea for a sine plate! I Love this idea, no need to remove the vise. Just secure the sine vise to a vise and mount parts to sine plate or vise to sine plate. I have been needing a sine plate and this just might be the ticket

Great mod !

Wow! You guys have given me so much information! At the moment I need to get back to making a new spindle pulley for my Sieg X2 mill with a treadmill motor. I will read all of this and post back here. I almost torn between working on the lathe/mill or reading up on this new found info! Thanks!

That you for answering my questions. Some of it I have never heard of. I am going to start searching the web for these other lathes and people you speak of. Sorry for my last post. It was a bit hard to read which I just realized now. I was trying to respond to you on my cell phone and it...

I will try and post some pictures tonight. Being Valentine's Day, I might get in trouble with the Girlfriend tho!! It’s a little machine shop part number 3595.

JCSteam, you’re absolutely right. I didn’t think about the electronic break. I wonder if it will be of any harm to the electronics or the motor. I do not know enough about electronics to rig up a switch that would deactivate the electronic braking while the disc brake is applied. As far...

Im going to apologize in advance for all the questions I have for you! The gib screw that you intend to modify, it it on the operators side or the back side ? What is the 918/920 and 9180 number stand for? Is it a particular series or model number or production number for the lathe? Mine...

I am unsure of what you mean by getting rid of the main drive disengage ? Its probably because this is my first lathe and have no previous experience on any other machine. Wouldnt it be easier to change the belt drive ratio ? I’ve never ran into an issue yet where I felt the lathe needed...

Awesome. I have made a lot of mods to my lathe so I have a lot to share. I’m currently modifying the compound rest. My compound rest is slightly different from yours. I have the modified version from Little Machine Shop. The T slots are eliminated and a step is machine in to the top of...

Is this thread just for questions on the SC4 or can I also post mods to the SC4 here or should I start a new thread. I'd Love to see more threads on the SC4 !

I have a spare DRO that no longer works. The battery holder is in perfect shape tho. I'm not sure how much is would cost to ship it to you if you are interested. Actually, I am wondering if you have the old style or the new style DRO's? Is it silver of black casing?

I know its an old thread but what DRO did you replace? Digital ReadOut?

Since I posted a picture of the carriage I might as well tell you about a modification I made to the carriage gibs. When you look at the gibs on the same side they do not make full contact with the bottom ways of the bed. They are tilted which makes for uneven contact. The allen head bolts...
