I have a rather critical part I need to thread and Im not quite confident enough in my new 30 yr old Jet 1024p to do the job (it needs a bit of work). Im new to PP and thread milling in general, and just wondering what to expect. I really dont want to scrap this part so any info or advice you gurus might have would be invaluable.

Thanks,
SD

I always tell people who are new to simply take a piece of aluminum the same size you are going to run and run it first if it comes out good you are good to go if you cannot do this then run it above the part it looks good then go for it. Either way PP does thread milling pretty easy so i think you'll be fine. Are you using a single point thread mill or? what rpm and feed? carbide cutter I assume.

Yeah I was thinking of using this one:

3 8" 14 40 TPI Single Pitch Thread Mill Brand New TiAlN Coated | eBay

Ive just never done thread milling before so im pretty nervous about where to start.

On a piece of scrap if you are that worried it does not matter if you mess up a piece of scrap aluminum. What is the thread you are cutting? What material? Inside or outside thread? How long? You can post your program on here to be checked. When in doubt take your time it's only one thread. What type part is it on?

Have you considered purchasing thread mills from Tormach rather than eBay? The prices appear similar.
