Thread: Mystery machine..........
21/07/2019 10:38:00

Hi Pete, sorry no pics here, you better go up to the green line at the top of the page, go along to the camera/albums and start an album, you transfer direct from your computer, best to reduce the size, I use 640 x 480. It took me months to get going, I was on dial up, and trying to put the photos direct without reduction, grrrr. Give it a go.

Thread: Deburring small items after parting off
21/07/2019 10:19:11

At the Menz Shed I am currently making parts for a tumbler for one of the many rock collectors around this district, there is a good source of aggates in the area. Basicly two rubber rollers 3" dia x 2ft long, and a 1/4hp 4 pole motor from a washing machine. I'v just finished rebuilding a diamond saw for cutting up some of the rocks.

I'v never seen one like that, but many years ago I made one, the rod I used was a double ended steel sock knitting needle about 8" long.

Thread: Finally sort of know which lathe to buy, but?
20/07/2019 12:55:40

I have no wish for a Myford, and I find the Box Ford A that I have use of lacking comparing those machines with my own 1326 BH Taiwanese lathe. My specs for a lathe whatever size, either belt or gear head with back gear/or infinitly variable like a Chipmaster or Raglan. Two shaft feed, ie., separate leadscrew and feed shaft.

Does the little Box Ford always chew out the bronze gear on the thread dial, it's obvious why with a keyway cut along the leadscrew.

If you buy an eastern lathe in NZ it usually comes with 3 and 4 jaw chucks, 2 centres and if needed a sleeve for the headstock to bring it down from 5MT to 3 MT. A fixed, and traveling steady. But if you are lucky as a mate of mine was, you open the box when you get the lathe home and you get 3 and 4 jaw chuck, 2 off each, steadies 2 off each, tool posts 2 off (some other poor blighter might have none). As the chucks are 8", I got a 6" 4 jaw about twenty years ago.

Interesting to read the machinery adds in Model Engineer, the Myford prices are away above reasonable(same here), I could have bought two of my larger lathe and still have had change when I compared it with a new Myford.

Thread: Angle grinders - Dangerous or not
19/07/2019 14:24:01

At least those things in the last link by Juddy are for a Weed Whacker, so limited to about 3000 rpm, not the high revs of an angle grinder. Still really too dangerous, one of those chains only needs to hit a rock to destroy it and bits of chainsaw chain flying every where.

Thread: Barrier Cream
17/07/2019 14:25:01

I used to use Kepthorn & Prossers lanolene barrier cream, there were two tubes, one for dry work, and the other for wet work. In the engine shop it was good when cleaning parts, and in the hanger when using paint stripper, and chemical etch on corrosion. The dry stuff was good for when you were cleaning the inside of the hopper on a top dressing aircraft.

Thread: Remembering Apollo 11
17/07/2019 13:56:41

Here in NZ we got radio live but the TV was delayed, the RNZAF sent a Canbera bomber over to Australia to pick up the film to go on the TV, I think the flight time record stayed until broken by Concorde(some time in the 1990s (I think). I have the LP "Apollo 11 We Have Landed On The Moon" produced by Capitol Records featuring official NASA tapes. Special narration by Paul Haney. It cost me the grand sum of $NZ1.99.

Thread: Supaburner's for Model & Toy Steam Boilers Explained
15/07/2019 12:48:13

Sorry Jim, can't even remember where I put it. The first one I built, the tank was vertical copper tube about 2 1/2" high x 1" dia, the loop tube 3/16" copper tube went into the tank near the bottom, and was bent up so the the hot end was above the top of the tank, it worked but was not a good design as the flame area was too high to be of any use. I did make a few more, but as I use gas for heating most of my hot air motors I didn't do too much development work, perhaps I'll have another go.

Got a tin boat about 26" long powered by a hot air motor with a single wick meths burner, perhaps a pressure burner would give it a bit of a boost, must try that.

Bit OT, anything refering to gentlemen reminds me of a famous speech to the military at the beginning of WW2 by a certain RAF Air Vice Marshal sent by London to set up our Air Force for war. He started the speech "men and boys of the army and navy, and gentle men of the air force". I think that is all of the speech that was remembered by anyone, and it caused a major rift in the forces for a number of years, here maybe more back then all were/are concidered equal, in fact NZ servicemen during the war ,when serving in UK often got a bit of stick, as the men and officers were sometimes a bit too "friendly".

On here there is no "class", in general you don't know who your talking to, and that's good(well that's how I see it).

Don't know what Blue Heeler used(probably similar). I use 1/4 OD copper mainly, but as I don't buy much, its a case of whats in the junk box. I did have some copper plated steel tube from a fridg, that worked ok, it was either 6 mm or 1/4".

Using a jockey wheel to tension the belt can also help to gain a greater wrap around, improving the drive efficiency.

Fibreglass wick as for lamp for aromatic oils, or threads pulled from woven fibreglass cloth, think I'v got some of that, it was called Dynel cloth 50 years or so ago, we used it for abrasion resistance on the leading edge of the tailplane of our Cessna topdressing aircraft. I have mad similar burners, but both ends of the burner tube went into the fuel tank, and the burner end consisted of a complete loop with the little hole in the bottom of the loop. I used asbestos string.

On second thoughts don't use Dynel, it,s not fibreglass, but acrilic, I forgot that.

Depending on the load a skate board wheel might do the job. Mount it on a swinging arm that can be locked in place, think of the alternator in your car, or if you are like me(no car), a car.

I had a Parker Hale sporting convertion of a SMLE Lee Enfield .303, I actually wanted a #4* that I had used in the RNZAF, in the 1960 that was our standard weapon, were as the army had gone semi auto 7.62 mm.

The PH 16 sight is for a BSA Sportsman .22 LR

Someone might help me, I have a thread in the manual machinery section How to remove a chuck from a Boxford model A. It's back on the 1/5/18. I had quite a battle over a number of weeks(only able to work on it 2 mornings a week).

Thread: Power supply problems for CNC rotary table
10/07/2019 11:16:18

I maybe wrong(quite likely) could it (the 230v to 110v power supply), be frequency dependent, I think transformers for 60 hz have less iron than a 50 hz one, this could cause over heating if the load were to get near the transformer rating, although I suppose it's an electronic rather than transformer supply.

The above company also has a Hawker Fury FB 11 that could pass that discription, it is all silver finish, not the flashy paint job and D day stripes of the P-47. Both machines big, fast and noisey.
