Electrical Newbie….please help!

Hi

Car batty for psu is Good, but use a holder that allows you to TOUCH one of the connectors to a terminal during testing, that way you have INSTANT disconnection,.

Loads SINK as much current as they want, no need to worry that a High current supply will damage the load (unless you have a short circuit)

Make sure your wires can carry the current your motor needs.

How about using an Ammeter in series with the supply? But finding a cheap >10A meter may be tricky.

How about a flexible drive or belt drive between the drill and the shaft to get clearance?

I fear that a lack of both electrical and mechanical knowledge may well doom this project ! A stainless leadscrew spinning at 1000rpm may well pick up(gall) and destroy the whole thing risking hurting the operator as well ! I would try to engage the help of someone suitably competant in the field. Analogies with metal cutting lathes are largely pointless as few have a bed of 5', lead screws are 20mm or more, and winding a carriage end to end in 1min is power travel not cutting. An accurate description of the project, it's goal and ideally a few pictures of what you have so far would enable us to offer better advice. Good luck. Noel.

Someone up post suggested not bothering with all the electrical stuff. The Wadkin R S Pattern makers lathe is hand feed with not hassle, built to run all day as well. Might give you some ideas?

Have a look here

You have recieved alot of suggestions and really we have no idea exactly what you are trying to achive. You discribe a jig and are actually making a lathe nearly. How about roughing out the piece and then using a router to finish to size, google router lathe.

There has been plenty of advice and guidance given so far on this topic and I think it is pointless adding more and more until the OP gives some more information.

On the face of it the original enquiry is a genuine request and one which forum members here are more than willing to assist with but until 'Steven Brown 1' re-appears we may as well leave things dormant.

Re reading the thread, if the objective is for the cutting tool to cover 1.75 M i(I think that 5 feet was mentioned somewhere) in 2 minutes, tha M12 threaded rod will be rotating at 500 rpm.

To me that seems pretty fast, from the point of view of safety.

A piece of 12mm studding, is likely tyo whip, evn if held in bearings at both ends.

And the warning about stainless galling is well made.

Also the actual workpiece will need to mbe rotating at an even higher speed, unless a screw threas dinish is required.

Normally, one would be looking to produce a smooth finish, so the Leadscrew, which is what bthe OP wants, will be rotating dar slower than the workpiece..

Given the 2 minute travers time, does the OP REALYY want a worlpiece rotating at somethging like 10,000 rpm?

is the machine even capable of that?

As Ian P says, the OP needs to define the objective first of all, and then to consider means of achieving it with the equipment and machinery which is available.

The OP seems to be talking about trying to make dowels a different way to everybody else.

I can link my products if it helps but didnt want to break any forum rules i might not be aware of on my first post.

.

I would suggest you give that a try, Stephen

… if anyone objects, the Moderators can soon delete any objectionable link.

I think Ian .P, three up post said it, but I am still in waiting to see what it is all about, love a mistery, usually have to be content trying to work out what the Mrs. is "trying" to tell me? lol.
