Thread: Copying Nuts and Studs.
19/06/2011 18:53:41
In addition to C.Jacobs posting, if you visit his fastening shop, they can reccomend a local engineering workshop who will saw the head off High Tensile bolts and thread them to order - ie: make studs.
Thread: never seen anything like it
15/06/2011 18:56:42
344 other people never seen anything like it - surely some one knows.
12/06/2011 20:45:42
Just picked up some new French metric (I guess the same as UK metric - just French made !) reamers from a car boot sale. I have never seen reamers like it, but was assured that they will cut accurate holes in steel, brass etc.
 
A third of the circumference have no cutting flutes, and the other two thirds have normal flutes. Anyone used / seen these before ?
Thread: A bit OT - Vintage SOLEX carburettor jet sizes

See if you can get hold of some SWISS REAMERS - these are 5 sided tapered reamers which come in sets from about 0.005" upwards.
Thread: Sharpening drills
07/06/2011 16:13:06
Been readin Model Engineer dated 1950 something.
 
The writer claimed he could sharpen a drill to make a hole as accurate as a reamer and had been doing this for a number of years. His secret was to sharpen as normal, then grind off the very tips of the outer edges of the cutting edges . It looked as though the cutting angle was a normal 118 deg and then the outer corner of the lip (.020 - .040) ground to about 45 deg.
Thread: Silver Soldering

How long has it taken me to find this out - too long. When fluxing up a job, use plenty of flux, enough to go well beyond the hot zone. When everything is cleaned up afterwards, there will be no nasty oxidised areas (Black for steel) to be cleaned off.
Thread: Axle box lubrication
01/06/2011 20:31:37
I am building a 5 inch GWR SPEEDY by LBSC. Among various questions, how do you lubricate the axle boxes. The horns have lubrication holes and below these are the holes in the axle box itself, but when the side tanks are in position, it will not be possible to get to either oiling points. LBSC says "place scraps of felt in the axle box for lubrication" Still the same problem, how do you get oil onto them.
 
Any ideas ?

Didn't find the magazine up to it. You could try POLLY ENGINEERING (France)

My best bet would be to take a drawing round to a small engineering firm, talk about what you are making, and ask if you could raid their scrap bin. You would have to take a chance on what you picked up. Sometimes the bit thrown away has a painted end with the batch number on it.

Thread: Workshop insurance
31/03/2011 19:05:23
Come and live in France. I insure with AXA for home insurance which covers outbuildings. I listed all my workshop tools with current replacement costs of just under 30k euro, and visited my broker. They confirmed in writing that I would be covered for contents up to 50k, and re-building up to 200k - ie house and outbuildings.
 
There was no mention of restrictions.
 
In my workshop, besides the normal extinguishers, I have an automatic powder extinguisher (hell of a mess if it goes off) . All solvents etc I keep in a steel locker - first line of defence, but I accept is not a totally secure soloution.

Could you use the cone of a loudspeaker to oscillate the electrode, then use a simple 555 circuit to drive the speaker ?
Thread: what thread is this?
22/03/2011 19:17:00
Just another thought - What is the thread angle ? 55 deg would suggest a British thread (Of Whitworth form) and 60 degree would suggest a metric one. 5 Deg doesn't sound like much, but would be enough to foul things up. There is another dodge, make your nuts half thickness and use two of them. It would allow for a bit of 'slop'
Thread: Bending Mild Steel Flat bar
07/03/2011 19:12:17
A barbeque, some charcoal and a hair dryer make a very hot, clean source of heat - just be carefull not to melt the hair dryer. Wear goggles as the flying embers are quite dangerous !!
Thread: Strange angle ?
07/03/2011 19:08:01
Are you sure the cross slide is BOXFORD ? South bend is the same form and fit, but I don't know about the protractor. I had a modified Myford top slide on my Boxford so that I had 'T' slots.
 
A standard Boxford cross slide doesn't have 'T' slots but it apperas your lathe has.
Thread: Taper reaming
01/03/2011 16:46:53
LBSC describes making taper reamers for injectors similar to a 'D' bit. Ie:- turn piece of silver steel to the taper required, then file away half the diameter (along the length of the taper) then harden and temper it. Stone the cutting edge such that it is 'sharp'.
 
Usualy these are short and used on bronze material.

Thread: Fire
23/02/2011 18:45:55
My condolances, but lets learn from it. I have an automatic fire extinguisher with a little glass vial like a sprinkler. I just have to be carefull not to bust the vial when I swing a bit of material past it. All my solvents I keep in a metal cabinet (Not fire proof, but would help delay spread of fire).
Lastly, I have itemised all my tools and put a current replacement cost by the side of each, and discussed with my insurers - left them with the list.
 
I hope you will have the energy to re-build - good luck

I live in France and take ME and enjoy etc etc, but does anyone know of a FRENCH magazine with similar content ?
Thread: anti-corrosion
15/02/2011 17:53:51
How about a tray of silica gel in the proximity of the clutch?
Thread: Broaching Keyway
11/02/2011 11:46:37
Seems a good way of doing it, but I would use steel for the shaft, the bearing area would be large enough not to cause damage to the flywheel, just make sure there are no sharp edges on the 'mandrel'. You may find brass is too soft to hold the tool bit rigidly enough.
