Thanks a bunch for the insight. If I do come across some silver brazing and black flux, and a hot enough torch, I may give them a try. I assume that some type of a cutting edge needs to be formed afte

Thanks for all of the input, but.................... I was hoping for some direction, and potential instructions on what has to be done to use the Unground Carbide pieces i have in hand, and pictured

Hey Guys, How are these used (see photo)? Do they need to be sharpened? Is there a specific holder for them? Any use for my SB9c? Thanks, Greg

No 42 in the parts list I have for my SB9c from 1957.

There are some cast iron legs available near me. Don't look SB-ish, but may work for you. Machine shop cut off machne whole, or parts: machine vise, 1hp 3/0... Machine shop cut off machne whole, or pa

the rounds were 416ss, and the flats were unknown ss. Got them both cheap/free. I was a bit worried from what I read on working ss, but I had no issues. A bit difficult to tap, but patience won over.

I patterned it after a blend of that and the ideas of Ralph Patterson, https://groups.io/g/Mini-Lathes/files/Ralph%20Patterson%20Mini-Lathe%20and%20metalworking%20projects%21/RalphPattersonML/ralph_pa

Hey Guys, Been a while. Based on your-all input, this is my shot at a QCTP. Still working on a parting tool, an a knurling tool holder, and probably another larger boring bar. Not he best photo (I am

You guys are a lot smarter than me!

So, The benefit of turning between centers is to allow you to flip the part while maintaining trueness (parallel and perpendicular)? If this is true, would you need a stub on both ends to accept the d

This was my grand plan was, but when I re-chuck, am not confident the top and the bottom of the base will be parallel, not that the bottom of the base will be perpendicular to the shaft.

Hey Guys, Looking for a little help on the order of operations to cut a post with a plate on the base and a hole bored threw the assembly. See attached for an idea of what I am working towards. Ignore

Jack is the big winner of the day today. Thanks Jack. I used the "Ride the Gear Train" as suggested by Jack. And got a 13.09 TPI Thread. An error of ~0.07% off of the 13 TPI. I used the following gear

Trying that as I type. The issue I am stuck on at this moment is that it is using combined gears other than the standard 54/18 and 72/18. I am confident that there is a switch I am missing to restrict

Hey All, I need to cut a 13 TPI thread on my SB9c. According to the change gear diagram, I need a 32 tooth, a 52 tooth, and an 80 tooth. Unfortunately, I am missing the 52 tooth change gear. Can anyon

Keith, Looks like some excellent work. I understand you most likely used your mill to cut the dovetails, but what direction was included with the plans relative to cutting them with a lathe alone? Tha

Bill, Thanks a lot for completing the research project for me, and sending me all of these links and information. Now time to digest it all. I will go down the DIY trail now. If it does not turn out w

Hey All, I've got a SB9c. Looking for project ideas to refine my minimal skills. How about a QCTP? I understand that you can buy an adequate QCTP for $150-$200, but shouldn't we try to make what we ne

Just picked up some Birchwood, Perma Blue from the local Farm & Fleet. I little pressed for time on this one, We'll see how it works. If it looks like crappola, I'll clean it off with a bit of vinegar

Hey Guys, Looking for a safe, and relatively inexpensive method to "blue" some mild steel. biggest piece is about 0.75 diameter x 8-inch. Thanks a bunch, Greg _._,_._,_
