It works very well indeed. I was lucky enough to use a vacuum furnace with a very large hot zone that could be stabilised to a few degrees Centigrade. It also had the ability to quench rapidly with Argon.

The only drawback was that the furnace cost around £15,000 around 25 years ago!

Well, got caught out well and truly! I even sent birthday greetings to my friend this morning. I can always remember his birthday, 1st of April. So why didn't I twig? Brain out of gear is my excuse!

Andrew.

Somehow, I think you might have a very large flame produced! Not a good idea.

Andrew.

Dave,

Take a look at the cost of Titanium, you might just change your mind.

Keith,

It was never my intention to braze or silver solder using TIG! I was interested in TIG welding a copper boiler. At my age I will probably buy a commercial boiler!

Andrew.

My Myford 2MT collets and also my Arrand, screw on nose, ER25 collet set give very little run out at all. I choose the appropriate style of collet for the job in hand. As usual horses for courses.

You would not believe how thick the filler can be! I followed David's advice and then used Paragon paint. Take a look at their web site it is full of good advice.

Hello Ian,

Yes Tracy list the 1/2" x 22 tpi in both Whit thread form and UNS form (whatever that may be!)

Andrew.

Hello Nick,

Yes I noticed that too when researching this oddball sized tap. I have come across special tap sizes before, but there were always some sound reason behind their use. With many threads near this one, I can't see much logic to its existence.

Andrew.

Sorting through some odd taps and came across one with the above dimensions. It was made by LAL Ltd England.

Tracy do two taps of this size, one with a Whitworth form and the other being UNS.

Looking up the Whitworth sizes, 1/2" x22tpi isn't a standard thread. Likewise for the UNS family.

So is this simply a special, or is it a member of some long since defunct series of threads? Just curiosity on my part.

Andrew.

Because I read the site, maybe several times a day, I never log off (bad security maybe!). I find that at times I need to log on several times a day and then I will go several months without having to log on at all! This has been going on for years. I don't think any of the explanations cover this observation!

The mystery doesn't bother me in the slightest. I simply recount it as evidence for computer savvy people to work out what might be going on.

Andrew.

I didn't know there were standard colours for patterns. Where do I find the details please?

Andrew.

I have done such a mod to a similar lathe. There re several variations on the web, but take a look at "Tricking out the 920" by Steve Bedaire (Sp?). This details one approach and there are several others (See the Yahoo 920 forum).

It is simple and straightforward and the modifications are all very similar, although I have not seen the ME version. Well worth the effort.

Andrew.

I have also had similar customer service. I had a problem with a parting off tool holder. I rang them and next morning I had a replacement in the post. Told me not to bother returning the faulty holder.

I can't praise them too highly,

Andrew.

Hello Neil,

I (and others) have used Indium Gallium eutectic as a means of making good contact with electrical probes on doped semiconductor material It basically reduces contact resistance to very low levels.

Andrew.

The real snag is that you divide both sides by a-b-c which is equal to zero. Dividing by zero is a no, no as the result can have any value.

Hello Brian,

I used 6" fixings for my kitchen cupboards and glued the fixings in place with Gorilla glue. This usually works a treat. What happened in my case is that the thermalite block. fractured around the fixings, allowing the cupboard to tilt forward. The top three fixings and those in the middle ((1/2" plywood backing) came adrift. Each surrounded by a core of thermalite brick!

Bisley drawers would have fared much worse, due to their greater overhang. Maybe if the walls were regular brick, I may not have had the problem. The suggestion of stacking Bisley draws defeats the object of keeping floor space clear for machinery

Best wishes,

Andrew.

Hello Brian,

Don't forget that Bisley draws are very deep. I would be filling them with very heavy items. This would exert a pretty high strain on the fixing items. Most modern interior walls are breezeblock (Sp?). I doubt if even raw bolts would be a satisfactory and safe fixing.for the sort of couple involved. I certainly would not feel safe in the vicinity of a loaded wall hung Bisley set of draws!

I have had problems with ex kitchen cupboards in my workshop. Load them up with our type of goodies and the cupboard started pulling away at its top! The major problem being the crumbly lightweight thermal blocks in my workshop!

Andrew.

Bisley draw systems are fine, but wall mounted they are not. So it is a waste of time recommending them for the OP's use.

I would also be interested in a wall mounting solution such as the OP has requested.

Andrew.

Try sending a PM.
