Thread: Fixing Eye bolt to old Lead longcase weight
26/01/2020 18:29:29

Hi Chris,

How about using a oxy -acetylene torch or (a propane torch, I have not not got one so don't know if you would be able to get a small enough pool of molten lead) and create a molten puddle in the centre top, and with a pair of pliers pull the nail out you could then insert your eye bolt into the molten puddle an allow to cool, or just allow to cool drill and tap as necessary.

Hi Dave, ,

What I have done in the past is turn up a button on the lathe bored at crest diameter, with a small countersink at each end, then use this to align the tap until well started then you can remove the button and continue tapping as required.

Keep this button in a container with your tapping drill etc.

Neil

Thread: Bolts & Screws using friction only to hold (or fluted)

Hi Richard,

Could you take a standard coach bolt and reduce the depth of the squqred part then counte-rbore a standard nut to fit over the square reducing its depth if necessary..

Thread: Suggestions to pack round DC motor so bracket holds

Hi Chris,

A possibility would be to use insertion rubber, available in a number of widths and thicknesses and available in nitrile and neoprenr which should prevent stickiness developing if there is any stray oil about.

Jeff,

you may be able to get a second hand switch from Depanoto that is in better condition than yours our helpyou with seeing what is required.

I have often managed to get parts for my Renault NN sent to NZ.

Alan ,

Another couple of possibilities are the Driving Creek railway in Coromandel. This is a small gauge electric loco that was originally used for carting mined clay for a potters collective. But has been lengthened to include several causeways bridges and a tunnel which takes you up to the "Eyeful Tower" a magnificent look out over the forest and surrounds of Coromandel **LINK** To get there you would need to go through Thames An old mining town and up until recently a lot of Heavy engineering.

Also a possibility is The Northern Explorer a sightseeing train from Auckland to Wellington(or V/V) that passes through the volcanic plateau and which passes over the "Raurimu Spiral"where the railway passes through a series of tunnels, viaducts and bridges to enable a great height change yet maintain gradiemts suitable for railway A great feat of engineering design and build. **LINK** If travelling by road there is a roadside model that can be viewed.

Hi, one of the problems with boring bar versions is the sharpening of the toolThe following U tube video would seem to have found a very good solution to the problem.

I hope this is of interest to those that have built boring bar versions of ball turning tools.

Hi Wout,

this is what happens if you use a flammable gas incorrectly!

Hi Tim,

would Fleming's Left hand, and Right hand rules explain why it is motoring in a different direction?

Thread: 1959 Nsu quickly

Hi Dave, One idea for your transfers would be, if you can create your own artwork (designs) would be to output them onto “ Colour Laser Printer Decal Paper” (search Google) and output them on a colour laser printer. Ink jet papers would be unsuitable as the inks are too fugitive.

This process could also be possibly used for clock and instrument faces and mounting onto litho plate material, the backgrounds of which could be achieved with either oil or water based paints for the background.

How to split messages?

13/03/2019 20:56:24

There is also a product that was used in the printing industry called “Nyloprint” that used (I think an alcohol solution) to do the etching. (https://www.teamflexo.com/pdf/nyloflex/nyloprint%20work%20manual.pdf.)

From memory using a point source light and the transparent nature of the plastic a shoulder is automatically developed, these could possibly used as patterns for casting.

This could be food for thought and investigation!

Thread: Extracting a dowel pin from a blind hole
28/01/2019 07:27:22

Could you apply a needle point grease gun to the already drilled hole and use the hydraulic pressure to force the pin out. Mechanics use a similar method to drive the spigot bushes out of a fly wheel,alternatively enlarge the through hole to a small pin punch diameter and fill with oil, then drive the pin punch into the through hole refilling with oil when necessary.

In the area where the nut will rest, cross drill your 8mm bolt with approx 2mm drill insert some weedline plastic and screw the nut up, this cuts off the excess length and is similar to a nylock nut and readily adjustable.

Thread: Why did the tap stick?
24/09/2018 20:30:07

Rather than “not done it yet’s” theory that the hole is not straight could it be that the tap is not quite straight. In that case the tap will eventually bind. My thoughts for a cure would be to re-dill and fit a Helicoil.

Thread: Aircraft General Discussion
21/09/2018 20:34:50

Who would want to silence the most beautiful mechanical noise with a silencer?

For me what mechanical noise is more beautiful than that of a Spitfire doing a “BeatUp”

The sound of the V12 Merlin with stub exhausts, the whine of the supercharger, Doppler effect of the aircraft approaching and receding, combined with the subtle and varied propeller wash and general wind noise!

I have not seen the movie “Spitfire” yet but look forward to doing so.

I live within 3km of the Ardmore Aerodrome home of the NZ Warbirds Organisation where there are 5 Harvards based, Catalina, DC3 Yak and many other aircraft. There is currently I think the third rebuild of a Mosquito being undertaken I believe it is due to take to the air within the next two months. Then the fourth rebuild will commence. Lately the Spitfire has been going out once or twice a week, always a joy to see and hear, unfortunately no “Beat Ups”

Hi Stirring Moose,

Some time ago I was searching for hollow brass rivets for the cone clutch on my car, and came across the follows sites.

Hope they may help you with your search,
