Mine are the same John.

So, are the Aikron, Touch and DroPros.

I'm tempted to order one of those scales to see if I can fit it on the South Bend. It would give me an indication of how much wear there really is on the lead screw.

When I made the ACME lead screw for my Gingery I found I had to tweak the cross slide as the carriage travelled along the 18" or so of thread. Wear in the bed caused the tool bit to drop ever so slightly and that resulted a tighter thread in some places. So add lead screw wear and bed wear it's amazing I can cut threads at all.

I even found this 100mm long thread I did last night flexes ever so slightly in the middle and that's with a 0.003" deep cut and 0.001" final pass. The spring passes still removed a tad.

A major complaint about cutting threads entirely with dies is that they can't be guaranteed to be concentric and/or to not impart twist to the part, especially smallish ones. A way I have found to deal with the trade off between this and trying to single point threads on a clapped out lathe is to start the threads on the lathe, cut to less than full depth, then cut them to depth with a die. The die will follow the started threads, will be straight and will not cause twist in a thin piece of material. YMMV, but this approach "has worked for me".

Of course if you need acme, multiple start, or anything fancy this won't help.

That's not something I would have ever tried on my own. I usually choose a path and then beat it to death till it complies.

I like your hybrid approach!

Oh, I am such a sucker for one more project! And I haven't done any electronics (or software either for that matter) since I retired a couple of years ago. Yeah, sure put me down for one. But Just One ! Really! Don't try to convince me I need one for the lathe too!

Hi Jeff please add me to the list if there is one left @Tomc938 I am in Ottawa as well so it wouldn't have to ship and I can maybe pay Jeff directly and and you can take it off what you will owe him if that is ok...
Thanks for doing this
 
Tomc938 said:
You sure could! I don't know what the cost would be, but I could send you the files @slowpoke put together and they should be ablate give you a quote based on that. If I understand correctly, they would not do the connectors or ESP chip. Just the little bits.

And @slowpoke did all the work. I was just the project manager. For those of you who haven't worked with a project manager, this means: I don't really know what needs to be done, what it takes to get it done, or if we'll ever get it done. But I have a nice office.

I assumed you were looking to get one done for yourself.

Yeah, I would not want to go head to head with Yuri either. He did the grunt work.

Hi guys I would be interested in two boards for the group buy if its still a go?

Or if no group buy I would be interested in the gerber files and I will order my own. I have am getting ready to order nanoels boards from jlpc and I can add more to my order.

If you're looking for two bare boards, I have them. They would fit in an envelope, but would be a bit more than a letter for shipping as I would put 2 sheets of cardboard to protect them, so it woudl be a bit thicker and heavier than a letter. Probably still under $5 for shipping I would think.

FYI: We have two threads in one here. I have the bare boards that Jeff designed. I can ship it to you, but you would need to get he parts and solder them on. And they are small surface mount components, just so you know.

The other thread is looking into an order where the new board design would be made - and I think - populated by PCB way. Cost would be higher, but no surface mounting soldering needs to be done.

You'll need to clarify: Are you looking for a bare board? That I have.

I THINK Jeff (@slow-poke) is going to look into getting some made and assembled by PCBWay, once they find out the cost.

I think this is an important nuance. I know he didn't discourage this in the past, but I think his business model is changing. He is expanding his business, and I believe he has dropped support for systems using his software that he didn't make. It is an evolving situation.
 
Susquatch said:
I hope that never changes because I like that approach. DIY is sorta who we are.

Still it's good to remain vigilant that we don't cross the line between what is ok and what isn't.

Except I don't think he's released the software so it's not very open as reverse engineering a PC board is pretty easy.
