|Thread: security Wheel bolts|
If it is the rotating sleeve type I have heard that hammering a socket over the sleeve can crush it enough to give enough grip to undo it. (Probably best not to use your best Snap On socket)
|Thread: FLORID SCRIPT|
I think Rory Gallaghers Strat must be the ultimate distressed guitar, Fender even issued a replica, why I don't know but I did take a trip to Harrods for a close look at the original even though I saw Rory play it at a few gigs.
|Thread: What size drill|
Jobber drills are tapered towards the shank, I seem to remember a figure of about a thou per inch of length. The web also thickens towards the shank so a much sharpened or resharpened broken drill will have a large chisel point and require thinning. All my drills (mostly Dormer) measure undersized the same as Andrews. I find that if the finished size is important then double drilling will give a more accurate fit and can even be a bit tight. If freehand sharpening is used then it is very easy to cut oversize unless great care is used to keep the cutting edges the same length and the chisel point the correct angle.
|Thread: Will they add the drill or tap you most often break ?|
I did a small repair on a 1000ton Demag crane and the crew told me that if the crane were overloaded it would send a report to Demag so they would have data if any claims were made for failure of the crane fabrication. The machines are watching us.
|Thread: Anyone fancy a chew-chew restoration.? ;)|
That will need a big bucket of brick cleaner!
|Thread: Pros and Cons of the ER collet system|
Yes Raymond, tongue firmly in cheek, I use ER on my mill and lathe for work and tool holding also use on JS hex and square blocks and have a small ER 11 fitted on my Arrand spindle. No complaints at all. I suspect that most of the home workshop community rarely approach the limits of the ER system and will be entirely satisfied. The industrial user will want to run near the limits of maximum machining rates to maximise productivity and will thus expose any limitations of the ER design.
Lucky I haven't binned my Clarkson Autolock yet. Sounds like this ER idea is a load of rubbish!!
|Thread: Is CNC cheating|
I see you have been busy since Barbarian Shaun. Nice job yet again. Can anyone be serious that you didn't make this magnificent creation? A CNC mill will make nothing until someone creates a task for it to do.
If Shaun Wainford was making his Barbarian Motorcycle by hand I think he would still be a long way from completion. The great thing about CNC is that it pushes the boundary of what can be made on a mill or lathe. I don't have any CNC equipment at the moment and enjoy hand control but power feed is close to being fitted as this produces a better finish than I can, even when I concentrate. I once watched an NC Marwin make a 2ft diameter turbine, it took about six weeks to make. That was 38 years a go, to make it by hand the customer would probably still be waiting.

If I were building a V12 or 18 cylinder radial engine I would be wishing I had CNC. I enjoy doing a job once but repetition gets a bit boring. The time invested in learning CAD and using a CNC machine would probably pay dividends in the long run.
Building loco's and traction engines can be done with the same process as the original but I doubt the parts for a gas turbine could be made by hand control of a mill, at least a copy mill or CNC would be required. One advantage of CNC is that parts can be designed to use the machine. If CNC had been available to the old loco designers they may have looked very different.
Where do you draw the line? Most people building a model will use some bought in components eg. Castings, fasteners, rivets, laser cut frames or spokes. Often the task of making the boiler is contracted out. CNC exchanges one set of skills for another if you do your own coding. I feel comfortable that CNC can be used by the model builder and not declare that it is not his own work.
|Thread: DRO with magnetic scales|
At the Bristol Show I saw this firm www.ems-i.co.uk I have no connection with the firm just reporting their presence at the show.
|Thread: What to get: Imperial or metric|
The most nonsensical thing about imperial measurements is fractions, if a drawing is dimensioned in thous then they are easy to add/subtract and relate directly to machines dials, a shame rules have fractions.
|Thread: Bench grinder bearing replacment|
I would go with tapping the shaft with a soft faced mallet, a few not too heavy taps should show whether the end housing is going to part from the body easily. There may be some notches on the joint line to allow a flat punch to be use to help part the cases. The shaft should not be too tight a fit in the bearing and should knock through without too much force. Extreme force should not be required or used.
|Thread: What would you ban and why? (Definitely tearoom!)|
My hearing has survived the best efforts of Motörhead and Ted Nugent and riding a Trident with a 3-1 exhaust that made your ears ring after 100 miles. My last hearing test was within the expected range for my age. Our village hall has a limiter that cuts power to the stage if the limit is exceeded but this is a joke as you could hold a polite conversation while the band played. Strangely a disco can play at a reasonable volume but a live rock band just trips it straight away. F1 came in for a lot of criticism when the current turbo setup emasculated the sound of the cars and speedway lost some of its presence when they silenced it. Drag racing seems untouched at the moment, maybe the sound is intense but it is very brief.

Sunday afternoon used to be a great time to go for a blast on the bike, the few Sunday drivers were nothing compared to the hoards doing their weekly shop.
|Thread: 6mm collet chuck|
Is this too much of a toy for what you are looking for?
|Thread: What Did You Do Today (2016)|
Tesco, Barton upon Humber
|Thread: bsf thread|
1/ 4 BSF should have an across flats measurment of 0.445" or 11.303mm. for practical purposes it is probably close enough as most bolt heads measure a shade under size.(assuming you have hex bar)
