Dan Gelbart has some interesting things to say about surface prep. for painting on YouTube

Den Gelbart: Building Prototypes part 6 of 18

It is the Minor, I own one as well. Also there's a picture with the model name on it in Mitch's album. That said, mine is MT3 and I wasn't aware they did an R8 option.

One of my lecturers at college studied hearing loss related to flying Shackletons many years ago. They found significant hearing impairment at certain frequencies at the end of long flights. After a couple of days rest the hearing at those frequencies came back. However, it was surely indicative of the likelihood of long term hearing damage due to repeated exposure.

Ian beat me to it. You should be looking to have the cable at 90% to the lever on the drum as the brake shoes bite onto the drum to get the maximum mechanical advantage.

I bought a used Warco Minor (RF-45 clone) from the classified section of this web site. Its MT3 and I haven't had any problem with that. Maintaining registration of the Z axis is a known issue with this type of round column mill/drill.

What may be a deal breaker for you is getting it in your shed. You will need an engine hoist to assemble it even if you have broken it down to transport it and get it through the door as it weighs 300kg with a lot of that weight in the head casting.

Couldn't resits a picture of me with one of messrs B & H's instruments when I was a young lad (second bass from the right).

While researching using form tools on brass I came across this video. At 50 seconds the machinist starts using a stanley knife blade held in his bare hands to finish shaping a piece in the lathe. My first thoughts were that it looked very dangerous. Is this a technique anyone else has ever used?

I see the classified ads section just got a bit more interesting last night

I have a bucket of steam for sale made from the tears of unicorns (metric only I'm afraid). Please pay me in used nine bob notes, washed dollars or gold. Generous discounts available for the illuminati - make yourselves known to me in the usual way.

International shipping available up to the 31st January, after that please arrange your own couriers as I'm blowed if I known what will be happening then, unless you live in Tonga, I hear we have a trade deal in place with you...

I feel your pain brother! I've just been editing down somebody's 10,000 word article to 3 instalments of about 1,500 words each.

Had a similar experience with ML7 gears from RDG a few years back.

I used to be the MD of a company supplying chemistry to the aerospace industry amongst others. As it happens we were also a subsidiary of Henkel (who own the Loctite brand) for a while. All our products were supplied with 'use by' dates not because they would degrade over time but because it was a requirement of our customers.

The storage environment is the biggest variable in shelf life. One of our products was just a mixture of two salts, when asked for a use by date by one customer we tried to explain that in a damp warehouse one or two days at most but in a dry warehouse we could put as many millennia as they wanted! Another important variable is exposure to UV rays and the embrittlement of plastics. Likewise, some products will embrittle plastic over a period of time - HP sauce being a good example. That is why most sauce bottles have around five layers of different plastic in them.

In the end we settled for a standard two year shelf life as that was what our customers wanted. Nice little earner for us as we would then charge to take back out of date product from the customer, re validate it and sell it back to them. Deep joy.

Builders expanding Foam Filler such as this?

No Nonsense Expanding Foam Filler

Interested, but as I'm at the Midlands Model Engineering Show the day before and the Stafford Classic Motorcycle Show the day after I think I might be pushing my luck a bit!

Just followed the link and watched his air bearing CNC machine. This guy is in another league compared to the Americans that post on YouTube. Thanks for posting the link.

I would recommend a look at the ArcEurotrade wedge type tool posts as well. I changed over from a Dixon type on my Myford ML7 to one of these. They also stock a range of sizes of this type of tool post.

Good old asprin. I have just started on a five year clinical trial of asprin following prostate cancer surgery. There is some evidence that taking asprin while in remission can reduce the chances of a reoccurrence.

Hi Chris,

I am no expert but at last year's Midlands Model Engineering Show I attended a lecture by Keith Hale from CuP Alloys that was all about silver soldering and brazing techniques. He has published a book called A Guide to Brazing and Soldering - everything you wanted to know about silver soldering but were afraid to ask! I have found it useful.

I'm an ex-accountant and can still add up a column of figures in my head quicker than my son can on a calculator (and I'm much slower than I used to be). I love annoying him by giving him the answer half way through his calculations

Why do manufacturers stamp the drill size just where the chuck jaws go?

Hi Jim,

I'm based in Northampton as well. I have a Myford ML7 and a Warco Minor MIll/Drill. What I don't seem to have is the time to spend on them that I would like!
