|Thread: Making split bronze bearings [ silver soldering ]|
If the mating surfaces (After boring) are big enough, superglue can sometimes be sufficient.
|Thread: Recommended base flashing for an external wall|
We use zinc sheet over here as lead is fast becoming a non preferred metal to have around.
|Thread: Milling curves|
For a low cost solution, if your vice sits on swivel base, you could hold the piece in the vice, offset from the centre of the vice by the required radius. Mill a flat over the end of the component. move the vice around a few degrees and make another pass. You could do that for 180 degrees of rotation of the vice. Now turn the component upside down and repeat (if you can't achieve full depth on the first passes).
|Thread: Mystery Starrett vice|
We used to use them to hold a rule in place when marking off rivet holes onto the edge of sheet metal, very useful when the panel was curved.
|Thread: Return key|
Has the forum site been improved, The RETURN key now works on Apple Mac "Mojave" instead of using Shift Return.
|Thread: Boxford tool post|
Buy extra toolholders at the same. Not all toolholders are comparable with whatever brand you buy.
|Thread: Boxford VM30|
Lets assume you have the bearings loaded up about right, then there may be too much grease in the spindle bearings! How much did you put into the bearings as they don't need much plus if you topped up by using the greasers it could overload the bearings and that would cause them to heat up - happened to me on my Boxford AUD.
|Thread: What is this grinder?|
Interesting that there is a reversing switch on it. Is that so that left handed workers can use the other side of the wheel ??
|Thread: Boxford Screwcutting box / Leadscrew binding|
Don't overdo the headstock greasers. On a cold day, if I screw the greasers down a couple of turns, it will reduce the speed of the headstock until things warm up. The headstock bearings don't need much grease. What gear train have you got between the headstock and the leadscrew ?
follow this link and print yourself the boxford manual.
|Thread: A Clash of Rivets|
If the Oxy-acet is available, I would preheat the firebox with propane, but not up to the point of melting the existing rivet joints, then swap over to Oxy-acet. If possible, use a lower temp silver solder as you don't really want to keep melting existing joints.
|Thread: Newbie Boxford owner saying hello|
Plenty of Boxfords on this site - ask away.
|Thread: This looks like a bargain|
yes, its in France, BUT !!
|Thread: New Toy|
Crikey - Do you get inside the box and shut the door to keep the workshop clean?
|Thread: Boiler material|
just a thought, and welcome views of others. I use disposable CO2 mix gas bottles, 300 mm high 100mm diameter and wall thickness of 3mm. These have a working pressure of 100 bar at 20 deg C and test pressure of 145 bar. Made of steel and about 2.5 litre capacity. Could these be used for a vertical boiler, drilling the end caps for fire tubes etc etc.?
Ps Usual excuse for horizontal picture (Horizontal boiler ??).
|Thread: What Did You Do Today 2019|
Had to replace the bearing in a Guy Noel cement mixer - Simple, take out the top circlip and the drum falls off to reveal the second circlip. Remove that and replace bearings etc. Not so, it wouldn't budge. Tried heat, WD40, brute force including a sledge hammer and aluminium 3" diameter drift. Plan 'B', looked inside drum to see that the bottom of the drum had a rusty hole in it and cement had entered the bottom bearing. Used the angle grinder to cut the bottom of the bearing housing off and with some ugly brute force, and cutting disc, removed the bearings in pieces. The repair is to make a new bottom bearing housing from a disposable CO2 cylinder, replace 2 x new bearings and job done (Perhaps).
|Thread: Aircraft General Discussion|
Interesting, As an apprentice at Weybridge, we used Schleron image photography for taking shockwave photos of wind tunnel models at mach 6.0 back in 1965. The breakthrough is doing this via telemetry in free air. Back in the day, the "flash" came from a bank of high voltage charged capacitors. During a 30 second run, the angle of attack could be changed 3 times, with 3 photos being taken from separate banks of capacitors. The wind tunnel working section was between a huge steel chamber (Statosphere chamber) and a barage baloon inflated with dried air which had passed over huge trays of silica gel. Either side of the working section were huge gate valves. These were closed, the "strato chamber" pumped out to near vacuum. When the "go" button was pressed, the gate valves opened and the air rushed through the plenum section, click, alter angle of attack, click etc and 30 seconds later it was all over.
|Thread: Can opener - the holy grail in engineering?|
Neil, ring pulls on cat food and pilchard tins are a no-no. The lid flips up and flicks fish gravy in your eye!
|Thread: Silver soldering a blind 'mortise and tenon' joint.|
Also I suggest Tenacity 5 flux for the joint as you are using stainless steel which quickly oxidises and prevents the solder wetting the joint.
|Thread: Machining cork!|
High speed and sandpaper, if required, glue sandpaper to a flat block of wood.
