Hi Guys,

Lots of pictures in this post !

I've been doing some more work on the punch and stamp holder body. I cut a piece of plate 12 mm thick steel plate 2 inches (50 mm) long and milled it...

Hi CErnewin, Guys,

Welcome to the forums.

A nice looking hammer, though I would suggest it is a bit light for a cobbler.

Could very well be the same manufacturer but a different production...

Hi Rooze, Guys,

I rather suspect that casting would be a more expensive and time consuming method of production ! That is unless you are going to go for Die casting, producing millions, in which...

Hi Guys,

There was a picture posted, I think by Steve (OxxAndBert) of one that he made from some steel bar !

Hi J&H,

There is often a residual resistance at the ends of a mechanical potentiometer ! This is caused by the moving contact surfaces within the pot itself. An ohm or so is a fraction of a...

Hi Joe, J&H, Guys,

I've made the assumption that the internal pot causes the welder output to be maximum amps when the slider is at the VCC end.

Based on your diagram (Joe) setting the internal...

Hi Chris,

The ones that I've seen use a loose pin on a chain to put in a hole and a bolt to stop it rattling. A friend of mine has one and he's welded it in place so it cannot move, he now uses a...

Hi Grahame, Could you please correct my spelling in the title. It should be "Metalwork" Thank you very much !

Hi Guys,

J&H, whilst your drawing is fundamentally correct, if the wiper of the internal pot is at the end where VCC is, then the resistance of the internal pot is effectively in parallel with...

Hi Chris, Guys,

Actually considering just how difficult it is even with a swivelling head to get the machine cutting dead square again, I couldn't recommend it. At least with a fixed angle block...

Hi Dave,

Yes I'm very very happy with the DRO. Up to getting and using one, I hadn't really given it much thought. But since my wife insisted that she should buy me something for my birthday,...

That is a basic 6X4 bandsaw, mine is/was identical except for the colour. I'm very happy with mine, but you do have to spend a fair amount of time setting it up to cut dead square in both planes. ...

Hi Guys,

I made the punch mounting plate this morning ! Its a piece of 3 mm thick steel plate cut to size on the bandsaw and cleaned up on the edges using the mill.

This is...

Hi J&H, Guys,

No it doesn't, the 5V is taken from the wiper of the internal pot. The "X" indicates the break where the internal pot's wiper is broken and swapped for the foot pedal pot. If the...

Good morning Grahame,

The Email was one of the notifications that I regularly get from the forum. It definitely came from here ! I kept a copy of the headers just in case, the original has gone....

Hi Steve,

The way to prevent the forum rotating your pictures is to get rid of the "EXIF" data stored in them by your phone/camera !

I do this by editing the picture and re-saving it. Simply...

Hi Rooze,

Welcome to the forum.

Do you have the machines that could make these parts ? If so then whilst CNC could do them it would probably be easier and cheaper to make them yourself,...

Hi Guys,

I turned another piece of aluminium bar in order to make a calibrated dial with a handle on it to fit "Y" leadscrew on the grinder.

391552 391551

I intend to calibrate this dial...

Hi Guys,

I think Pipeclay hit the nail on the head ! If those surfaces are not flat and parallel to each other then you only get point contact.

Some time ago I flycut a clamp plate for a lathe...

Hi Guys,

I've now got the frame finished for this tool !

391548 391545

This is the frame screwed together.

Hi Dean,

Welcome to the forums !

If you have access to a 3D printer it should be an easy part to make !

Hi Guys,

Did anyone get an Email from Metalwork Forums this morning about this thread ? The very latest post !
Al320g lathe headstock oil procedure


It was a massive 188 Kb in size ! It hit...

Hi Guys,

The one thing that I haven't seen mentioned anywhere is that it is important to make sure that the battery contacts are clean ! Any oil, grease or dirt will cause a poor joint. The same...

Hi Guys,

I've been cleaning up the pieces of steel that I cut up ! I've machined two pieces to size and using my new DRO marked and spotted the position of the holes to be drilled. The DRO makes...

Hi Guys,

Just an update.

I had a check up yesterday and found out that I have to go to the opticians on the 6th of May for a full eye check prior to being re-admitted for surgery on my other...

Hi Stuart,

Well your reply prompted me to actually count the spaces between the teeth of the gear rather than to assume !
Which I had. The gear is clearly marked 40T and for whatever reason the...

Hi Guys,

I have finished the drawing for the Graduating stamp holder tool. So unless I've made any mistakes there shouldn't need to be any changes.

The main body is made from 12 mm...

Hi Neevo,

Looks good, very professional !

That skateboard tape is also used on steps to prevent slipping. I have some strips of it attached to short lengths of wood that I use like a file on...

Hi Guys,

I don't have a parts washer as such, using any old plastic container, usually food ones that my wife throws out ! I like to use White spirit that is available in two and five Ltr bottles....

Hi Joe, Guys,

From looking at the circuit you posted the two variable resistors are in parallel. I did add the caveat that the assumption was that the internal pot was at maximum. Because you...

Hi Steve,

The screw down the middle pushes the taper apart causing the plug to grip the bearing bore.

Argh I've just re-read what I wrote, yes you are right, I've got the work order wrong....

Hi Grahame, Guys,

Its now day four and I'm just about used to the brightness. I've been using sun glasses which helps a lot, and the eye drops that they give you lubricates the eye preventing...

Hi Ben, Guys,

I've used those router bits many times as milling cutters, even on steel ! You do have to be a bit careful though. I found that it was not difficult to bend the 1/4" inch shaft of...

Yes ! But you need a smart phone to do that ! And I don't have one. Mine just has slightly larger buttons...

Hi Nev, Guys,

Somewhere on one of my backup discs I have the instructions and construction notes for a microwave oven transformer design. It uses a capacitor bank and a timer, 555 ic, to...

Hi Guys,

Thank you for your good wishes !:2tsup:

Because of information given when I was discharged from the eye hospital, advised about not driving or using machinery, her indoors has now...

Hi Grahame, Guys,

I cannot agree with you more ! The manufacturers attitude it seems is not to publish anything about nutrition or ingredients unless they are obliged to ! Making it smaller is...

Hi Guys,

How to remove a ball race from a blind bore came up on another forum recently which reminded me of a method that I used to remove one.

I turned a piece of rod down to be a tight push...

Hi Stewart, Guys,

Based on your post, I would definitely go for some 1/2" inch thick conveyor belting ! It will support the whole of the edge of the base, and once settled the machine will be...

Hi Guys,

Sorry about being off topic, but I wanted to thank all those people that offered reassurance and good wishes about having eye surgery to remove cataracts. I had surgery this morning and...

Hi Joe,

The two resistances are in parallel ! So the total resistance is halved. That is assuming that the internal pot is set to max resistance.

Hi Guys,

On my 6X4 the blade length is nominally 64.5" inches. But there is easily enough adjustment to go to 65" or even 65.5" inches.

I've also discovered that "Toolstation" here in the UK...

Hi Family Guy,

Nothing so sophisticated, I need 40 divisions on a 50 mm diameter ! The leadscrew thread is M6, so 1 mm or 40 thou per turn. I do have a gear with 40 teeth but that will only give...

Thanks Michael,
All the stamps are the same thickness, 1.5 mm so I had already decided that using single stamps was the way to go.

I watched a video, some time back where a string of characters...

Hi Guys,

Whilst my mill is a fly weight compared to most, I sat mine on a square of 1/2" thick rubber conveyor belting, the high spots mould into the rubber, the net result is that it doesn't rock...

Hi Neevo,

The reason that your pictures are being rotated by the forum is because the phone embeds data about the orientation of the phone. This is the "EXIF" information stored with the picture....

Hi Guys,

Just to finish off the trials and tribulations of fitting my new DRO. It was pointed out that I no longer have access to the table locks because they are hidden behind the glass scale !...

Thanks Michael,

Part of the design is that the stamps are tiny compared to a set I found in the scrapyard which are 1/4" square. I would like to be able to make the jig use other sizes of stamps....

Hi Guys,

I said that I would post pictures !

391496 391490

This is the set of "Pryor" interchangeable type that I have. The set was originally purchased in the late...

Hi Dave, Guys,

I hadn't realised that different symbols required a different force on them in order to get uniform impressions !
I was thinking of using a spring to drive a weight down onto the...
