Thread: turning small diameters
29/02/2012 16:44:10

Not as small prehaps but how to take 0.15mm from some 6.35 (1/4" mild steel rod . I want a polished surface finish on a 250mm long length. Suggestions please?

I tried doing it in steps but the suface finish is not good but from memory last attempt was silver steel. The end then gets screw cut M6 >it's for wood turning - making a pen mandrel !. Didn't fancy burnishing.

Regards Ian

sack cloth and ashes! The cutwel extractor does not work! Does look damn similar though ! Just incase anyone else has the same issue!
 
However I stick by my comments about them as they've taken it back without any issue and |I got some other tips instead

I have had it said that if you put 3 engineers in a room,and give them a problem that you will get at least 5 solutions, kostly contradictory and that each will argue ehir point.
 
Certainly looked that way in a club discussion evening we had.
 
I am not intending to make one of the aforementioned gadgets but the thought process is useful. he whole point in MEW , to me anyway, is to generate solutions. Sometimes the problem may not, at this moment exist ( for you ) but somewhere, sometime.....
 
Now off for a damn good weekends wood turning at Loughbrough!
 
Happy arguing! Sorry discussions folks!

Small ash mallet allows you to safely tap the inerts home with low risk. Mahogony is good too and you don't need a lot to make a tapping mallet!

It's a long sot but...
 
 
as anyone got an Iscar Do grip DGF 32 - 4 parting tool blade and the extractor / insert inserting tool ? I would like to know the centre distance betwwen the pins to enable me to make a wrench for inserting and removing the inserts.
 
Got the blade and suitable inserts but the tool I got ain't the right one to insert the inserts .
 
Made a dickinson holder for it, all going wonderfully until I came to the point of nserting the insert to enable me to set the tool height!
 
Tried 2 dealers by e mail but no reponse as yet. On that vein- anyone recommend any dealers?
 
Thanks Ian

I have heard it said that water cooling ( if you let it get too hot) can lead to micro fracture lines in the tool bit- anyone experienced this?
 
The Creusen is definately high quality. I went for an 8 " wolf industrial but also had a 6" Black and Decker "Professional" range grinder and can recommend them too.- damn site cheaper than a Creusen. If you go down the Creusen route consider their slow speed grinder as then you can sharpen carbon steel tools with little risk of over heating- it just takes a bit longer!!

Sorry if this suggestion to seems dim but with diamond slip files or a diamond wheel ( cheap at Harrogate last year ( £10 for 4 " wheel fine grit!) you can get a really fine tip / edge on carbide. Been doing this on router bits for years . OK the edge might not last over long but on delrin should be ok. Not sure about build up on Aluminium- was ok to rout but that was an accidental discovery a few years back.
 
On router bits mind you you count the number of strokes to each side of the cutter to maintain the dynamic balance. ( or it vibrates a lot and must be discarded / refined again! ).
 
Only 5 days to Harrogate !! Oh joy!

Hi Chris
 
please dig out the camera for the alternate style. Been thinking about making one for a while as I know you and MJG rave about them.
 
Trying currently to decide whether to part with a mk1 clarkson or a boxford T&C grinder as not enough room to use both! Life's full of hard decisions!
 
Are you doing Harrogate this year?

I can recommend the guys at York Club. Yes there's a lot of train talk but , if you ask, they really try and help! And there's a real fountain of knowledge to drink from.
 
 
It's definately true though that if you ask 4 engineers for an opinion on something you'll get 6 answers ( at least) , most of which will contradict each other on fundamental point!
 
In any organisation not just me clubs there are those that do a job and those that criticise it, that's life. Illigitimi non carborundum ( apologies to anyone who can do latin! )

1 think about a dehumidifier and insulate it BUT then don't use SUDs to lubricate when cutting .
 
2 put an oil filled radiator on a thermostat in and keep the temp above about 10C and you get less issue with condensation- plus it's nicer to work in.
 
3 wood floor is a good idea as if you drop something you don't damage it as much.

If you need to make the magnet weaker but a washer or plate on it. the magnetism comes through but not as strongly.
 
Only problem I've had with them is they're brittle ( as my sons 5 & 9 have proved ) so they don't bounce!
 
In Chris's "giving thread" I put how I use one with a handle in a plastic container to remove swarf etc.
 
Axminster list rare earth magnets but these are damn powerful !

at a push you can use a block of wood with a hole cut to a "close fit" on the lower stem and then  put a wood dowel / stick in theside of the block and get it where you want it.. eg grip in the tool post holder and spin the chuck carefully by hand having put the foot in contact with the workpiece.
 
 The only important thing IMHO is that the thing does not move whilst you turn the chuck as it's a comparison device not an absolute measuring device. You compare readings to centralise.
 
Complicated to describe but easy to make!
 
 
Thread: Unknown Tool

It's actually 3 tools. The circular one top left is a pipe cutter  for copper pipe.
 
The lower on is an adjustable wrench for tightening nuts as Ian says but someones put a cutter on the shaft ( sounds painful doesn't it ).
 
The half circular bit, top left , is an alternative head attachment for the adjustable wrench for bigger nuts!

Oh one more thought.
 
Always worth asking shops what they do with their plastic window banners when they've finished with them.
 
The plastic makes really good spacers to place between cutters in storage. It stops epoxy sticking to the bench or indeed anything else.
 
You may get a few funnly looks when you ask but then again....
 
You may just get funny looks anyway!

A Really good source of large donut shaped magnets is the Magnetron found in any kitchen microwave oven.
Just ask SWMBO if you've got a burnt out microwave anywhere ( usually is one in our house but maybe that's just my better half and children making bits for dady !).
 
Cut the plug off, leave it a bit ( got big capacitors in 'em these days and they hurt !), then open up and look for a strange fin covered bit attached to one side of the oven bit. That's the magnetron. pull off the find and CAREFULLY ease the magnets off the central spindle. Carefullt dispose of the unnecessary bits and you shoudl have a nice matched pair of 3" dia magnets.
 
Now if you add a length of broom handle though the centre of one of these, attaching with epoxy and put it in a plastic container with thye handle sticking through the top. You then have a magetic pick up for swarf etc which keeps your hand out of the way.
 
To get the swarf off pull the handle up to the top of the container and the swarf drops away.
 
This gadget is also really good at retrieving the "lost nut, screw or thingumy " that's gone under the bench or even dropped in the grass in the garden 'cos you can roll it around and if it gets wet- so what!
 
Chris and Bogs thanks for the interesting links and comments !

Hi all.
 
If you want to get ingrained dirt / oil / muck off your hands try kneeding a nob of " EMULSIFYING OINTMENT " between your fingers / hands.
 
Basically this is a very waxy base material  pharmacists use to manufacture ointments and the dirt / oil is soluble in the wax to a greater extent than it's soluble in / on  your skin  so it migrates into the oil phase of the ointment. This also means that you don't strip the oil from your hands so less skin splitting etc.
 
All you do is rub for a while then add warm water to the traces left on your hands and it gets most of it off.
 
Got to say though that I got some Lemon hand cleaner ( with grit in it) from a guy at York and it's brilliant!
