Hello Bill, I have had bandsaw blades for my Proxxon MBS 240 made up by;

This company will make any length of blade.

Hello Kevin and welcome to this excellent and friendly forum.

If you have any questions you have but to ask.

Brian

Looks very useful and a good make as well.

Brian

Am I right in thinking that 'inclinometer' should more correctly be 'clinometer'?

Pedants of the world unite (assuming that I'm correct of course).

Brian

In another thread I relate the sad tale of breaking an 8BA tap.

Well, I ordered a new one from Macc Models at around 15.00 on Friday with delivery by 2nd class post and it arrived at 0800 on Saturday;brilliant service!

And well done to Royal Mail also.

Brian

Just discovered that I needn't have made the holes blind! They will just go through without leaving a witness in the mating parts.

Also realised tht the two holes that I broke a tap in,needn't have been put in at all.

Must get my brain in gear next time.

Brian

Many thanks to all on here for the suggestions and offers. I've now managed to secure a small amount.

I first came across alum as a young apprentice with Crossley-Premier Engines. One of my first jobs was to pressure test valve guides which where hollow cast iron castings with water passages to cool the valves on diesel and gas engines.

They were tested to 25psi (as I remember) and any porosity or leaks were fixed by the addition of a teaspoonful of alum which VERY quickly rusted any defects so that a second pressure test could be carried out to ensure no leaks.

Brian

Very nice John, well done,

Brian

Many thanks for the suggestions all. The material that the broken tap is in is a mixture of brass and gunmetal.

I seem to remember that there is a chemical solution that has been mentioned before on here, that disolves the steel, but I can't remember what it is.

Brian

As is the 8BA Plug tap that is broken in a 1/8" inch deep blind hole!

Any (sensible) suggestions welcome, as is an offer of spark erosion near Mansfield with a financial contribution from me.

Please don't suggest heating it to red (it's a carbon steel tap) because it's in a silver soldered assembly!

Hello Jim and welcome to this wonderful forum. Now that you have the machining capability, what ae you intendng to do with it?

Don't forget, any questions just ask on here.

Brian

Many thanks for the PDF Gary, that's very helpful and very kind.

Brian

I wonder if an approach to the BHI (British Horological Institute) would be useful. They are normally very helpful.

Hello Diogenes and welcome to the forum. What are the intended uses for your workshop and machinery?

Brian

Hello Tony, placing the pictures in an album worked, very ingenious!

Brian

Welcome Tony, there are a number of bikers on here so you may hear from some of them soon.

I for one would be very interested in your helical grinding device. One way to share is to make an album and put your pictures in it. If you look for the green coloured banner at the top of this page, the 4th tab along is albums.

Brian

Just remembered; faces intended fr the Turkish market would have had the numerals marked with triangles so maybe the above is wide of the mark!

Brian

Many clocks and watches were made for the Turkish market, could the marks be Turkish (although I don't know how you would find out).

Brian

I've designed a couple of boilers in the past and I had all the calculations ready to present to the inspectors at the initial pressure test. No problem with getting the complete set of tests done with the subsequent issue of a boiler certificate..

Brian

It's always exciting when it works! Very well done, that's a real incentive to finish it.
