Stuff you have made today

[gaz1]

i believe its by hand that you thread it onto the bar using the tailstock to push it on at same time

 

[brightspark]

material needs to be held tight in chuck as the force threading is great @20 mm I start threading mine using the clutch on the lathe at slowest speed and then by hand or use the hand crank I made to start thread

 

[mechman]

When I was an apprentice in the last century we were told that a die nut was for cleaning threads up only, no one took any notice on the small stuff anyway.

So, really just ensures everything is 'square', as opposed to the old-fashioned way [mine ] of holding work-piece(s) in the vice and hoping you can guess true vertical? Or, faffing about with the drill-press.

Well, not technically made, more finished as it's been dragging on for a bit . Excuse poor phone pics

Also, if anyone has any spare pistons, conrods, bearing caps and bolts lying around, I'd be happy to have them for beer tokens.

I will send you a pile of rods/pistons in exchange for one of those finished items

When using one of these, with the work-piece in the chuck, do you just set spindle speed to slowest and free off the tailstock, letting the die [or possibly tap too] pool it in. Does it stop itself or do you have to hover over the "Off" button, watching like a hawk?

Rightly or wrongly when I do mine I get the thread started under pressure then once I have got it started I release the clamp and let it feed it's self the die holder needs a bar handle on to stop it spinning I put mine on to the cross slide and make sure it has free movement for the length of the thread .I don't cut them in one either I am on the slowest speed with the die open it is best to use split dies and use the back gear then pulse on the switch I have found that if the pressure gets to great that the drummond will throw the back gear off as it works on a over centre shaft if things get to tight I just wind the die back re lube and take another run then check the thread with a nut for tightless if it's tight I just close the die a fraction and do another run I didn't know you could buy purposes made holders untill I had made mine I saw the idea in the book the Amateures lathe

Edited to add if you want to see a video of it I will do one and post it up

Thanks, that would be excellent . . IlI' PM my details and can let me know carriage costs?

As long as you appreciate it could take a week for two to do, due to various 'healthcare' appointments coming up (weather, although improving, could have an impact too )?

 

[Ian James]

Yes, please do.

So here goes not the best filming firstly a still picture of the finished thread

 

[slim_boy_fat]

Thanks, Ian - appreciate the time taken to do that for us.

More plasma stuff I am afraid, it may get Tig'ed together after I am bored of playing with the puzzle and then powder coated, will have to wait and see.

That's brilliant!! Wish I had your 'vision'.

I wish I had the vision, this is a download off the Internet, I struggle to come up with ideas for anything arty.
Mine you will find are more basic, boxy etc. This I believe was originally meant for 2mm ply to be cut either by a small router or cnc laser.

There are a lot of ideas out there, some wonderful stuff that people have either given away to the wider community or, someone else possibly pinched and then put out there.

I bought some dxf some time ago and there are few of this type of thing included, many I have since found on other forums or websites as freebies.

I found this interesting and good practice as things get a bit more complicated I learn a bit more on the plasma.

A bit of Googling comes up with this, possible source(s)

This is one location I use.

I can also get some files from Plasmaspider forum and I also have bought a few from a few suppliers.

There is a website https://robinhillmachine.com that I think I would recommend for anyone that needed say a picture/portrait etc converting to a cut ready dxf. Credit where credit is due, some of the work I have seen from them is marvellous.
I play!

Adrian.

can you send me 6 cummins pistons, wrapped in a 6bt crankcase?

 

[mechman]

There is/was a complete 6pot cummins engine (on the links wold railway) doing nothing, It was a standby pump so it's done nowt and it's seized with standing, it's still on it's frame. I'm on hols till march so can't give any more info until then.

Nope but could do subaru ej20 engine parts as do bin cranks rods and pistons on a regular basis.
