Hi Alex,

I particularly like the "Cross Line" laser !

I will have to get one of those. Having an X-Y table on the drill makes it easy to move stuff about and get work centered, particularly...

Hi Guys,

One of the issues with Photolitho, is that the ink has problems sticking to the printing plate. So in order to overcome this, the plate surface is etched to create a myriad of very tiny...

Hi Ian,

I would suggest something like "Plusgas" to penetrate the rust. Although the application of a little heat applied to the casting might help.

Hi Lever,

As far as I am aware those images were photographs done on a glass plate and converted to lithographic images for printing. I think that the technique was called Photolitho.

Hi Chester,

I have a selection of dial indicators, my best one is 1/10000 a tenth of a thou reading ! My most used ones are 1/1000 a 1 thou reading. I also have a couple of tenth millimeter ones...

Hi RT,

My Myford will go up to 2400, and that's a spindle in a bronze bearing !

Hi Steve, Guys,

I've tried that ! and it still leaked...

Now that J&H has pointed out how to make one, a leather bucket is next. :U

Hi Graham,

There isn't much else you can do with that counter/lay shaft other than dribble a few drops of any general purpose oil on the ends. I use SAE 40 car engine oil on my lathe.

You could...

Hi Chester, Yes you could be that lucky !

Before you start dismantling it carefully check that the nozzle matches the oilers on your lathe ! It may not. Some grease guns have a mechanism that...

Hi Guys,

A little tip passed on to me, was to use a couple of folds of cotton or denim cloth between the nozzle and zerk fitting ! It does work to seal the joint whilst forcing the oil in, and...

Hi Chester, Guys,

Getting that grease out really requires stripping and cleaning properly ! Petrol is a good solvent for grease, but grease that has gone hard and set can be a pain. Simply forcing...

Hi Guys,

A quick one on terminology !

The Driven Element, is the one that is connected to the cable leading to the receiver/transmitter. All others are passive ones. In terms of naming the long...

Hi Kafie,

Yes the dimensions were calculated from a few rules of thumb !

The centre frequency is around channel 40 (650 MHz) not too precise because at these frequencies a mm is a lot. Notice...

Hi Guys,

For a while now I've been meaning to make a proper TV antenna for the camper !

The supplied rubber duck was rubbish unless you were sat within a few miles of the transmitter, even...

Why am I not surprised !

Hi Chester, Guys,

I know that I keep banging on about HSS ! But at least you quickly learn what works for you. You do learn about cutting edges and the shape required.

With carbide inserts you...

Hi Errol,

I agree that the starter was most likely the problem !

More often than not, the starter contacts weld together causing the heater filaments to continue to glow without the tube...

Hi Chester, Guys,

I agree 500 rpm is about right for a 16 mm drill in mild steel. Personally I prefer to go a little lower in speed with large drills, say around 350 rpm. The problem is unless you...

Hi Guys,

Most of the large roof solar panels produce between 38 and 53 volts. Its not difficult to use them for battery charging. I cleaned the one on my van roof the other day, it was filthy from...

Hi Ulyanov,

I wonder what it will go for ? I don't see things like that coming up on the British market !

Thanks. I crop mine for the same reason. I use a Cannon IXus 170 to take most of my pictures. Set to the smallest size, but they always seem to be big.

H Rusty,

From a quick perusal of your diagram, it seem that the switch selects the internal speed setting or an external control !

Hello Martin,

When I started posting pictures I think that I had one that was sideways, so the next picture I rotated it and it came out fine, so I always use that orientation. Now I've always...

Hello Martin,

Have a read at this link !

Hi Paul,

Forgot to include in my last post about getting your pictures to show the right way up !
Check out this link.

Hi Paul,

Glad you got it sorted. :):2tsup:

Hi Chester, Guys,

I've acquired the vast amount of HSS that I have from scrap yards, engineering firms scrap metal bins, been gifted unwanted stock. I suspect that most engineering shops will...

Hi Steve,

It been a lot of years since I did any line shaft work ! As much as I remember, the lower machine pulley was crowned so that when the belt was moved between the live and dead pulleys...

Hi Guys,

I may have got this wrong but I seem to recall that only one of the two pulleys had a crown. From line shafts, only the machine pulley had a crown, the line shaft pulley was flat.

Hi Glenn,

Yes that is exactly what I've found ! Particularly used in a flashlight(torch). They are always flat or nearly when you need it.

Hi Kafie,

I agree some of the newer ones are quite complex ! The older battery operated tools benefit the most from a battery upgrade.

As far as BMS is concerned I've seen quite a few just...

Hi Kafie,

In my experience these battery power tools are not at all critical to a few volts more !

In fact talking about batteries, the Li ones seem to hold their charge far longer than the Nmh...

Hi Normanby,

I've been using new and salvaged Li ones as replacements in some of mine ! Four 18650's will provide 15 volts, which is ideal for 12 volt tools. However you do have to be careful...

Hi Steve,

If you're going to make own pulleys in order to get the speed right, then flat belts have the advantage that they are very common and easy to get or make. A good source of flat belts are...

Hi Guys,

I promised some pictures and here they are !

This is one of the two pieces of 2 mm steel plate. I've marked out and drilled a hole depicting the centre of the 5" inch (127 mm...

Thanks Glenn.
I'm glad that someone is reading it. :2tsup:
I hope that you are enjoying it. Its not often that I get feedback. Questions and comments are always welcome.

Hi Guys,

With all due respect for brand name tools, I have a brand new Sandvik scraper and a new box of spare tips for it. It's never been out of it box ! To be honest I'm not even sure where it...

Hi Steve,

Many good scraping tools can be made from old files and a little time on a DE grinder.

I've also used pieces of HSS lathe tool blanks to scrape things !

Hi Paul,

Welcome to the forums.

I think that you will find that the ring in front of the bearing, is not pinned, and is a shrink fit. The rotor is pressed onto the shaft and secured by the...

Hi Guys,

JMTPW,
For a Laser, the frame I think would it be quite adequate ! Definitely not for a motor head. Vibration would be a killer of any precision !

Hi Guys,

This was the technique that I used when I cut the adjuster for the angle setting on my version of the Brooks TCG. Pictures in that thread.

Hi Mark, Guys,

With capacitors you can always use one of a higher voltage, never less. As far a capacitance is concerned, electrolytic capacitors have a quite wide tolerance value, usually as much...

Hi Guys,

Just got back from visiting one of the engineering shops that I've done work for in the past. I was offered the remains of a 10' by 8', 2mm thick sheet with almost nothing cut from it. I...

Hi Morrisman,

As long as they are dry and the coating isn't falling off, they should be OK.

Hi Nigel,

I meant to post this at the time but forgot ! Sorry.

Hi Glen,

Good to hear that you got your Diamond discs OK.

Last time that I looked, Ali-express had diamond lapping discs in sizes from 4" inches to 8" inches diameter in 1" steps. Quite cheap...

Hi Chester, Guys,

I used 25mm (1" inch) 1.6 mm wall tube when I made the replacement bandsaw stand. Its more than adequate for this purpose ! But I do appreciate your concerns about strength. One...

Hi Chester,

A diagonal cross beam and a shelf would work nicely on the base !

Hi Erroll, Guys,

Capacitors have no inherent charge/discharge limiting mechanism ! Unlike a lead acid, NM-h or Li. Where the charge rate is limited by the chemical recombination time. The same...

Hi Chester,

Welcome to the forum. :2tsup:

As Kryn says, we like pictures. :)
