|Thread: Woodwork Router Advice|
Hadn't thought of them !!
Basically, I need to fit new doors and frames - so it's locks, hinges and probably tenon joints or biscuits for the frame transoms.
Unfortunately, they're not standard sizes so it's going to have to be diy or lodsa money.
I bought a big one a few years ago for a kitchen worktop but have kept it in its box ever since as it scares me ... there's something about it not being bolted down - at least on my lathe I'm not relying on just muscle power to hold the headstock in place when taking a cut - it's very firmly bolted to the bed !!
Anyway - thanks all for the quick replies !
I'm sorry to blaspheme on this site - but I think I will need to shortly do some 'woodwork' !
Can anyone recommend a good book -specifically on use of a router ?
There's lots of help pages and videos around but I'd like something I can flick through and doesn't require plugging in....should also add that it's for 12 inches to the foot modelling - it's for new door frames in the flat...
|Thread: Washers (History)|
|The Titanic watch reminds me of the ashtrays that occasionally turn up 'made from metal from the airship R101'|
As a goodly number of the bodies recovered from the crash wreckage were burnt beyond recognition, an ashtray seems hardly appropriate. ..
|Thread: Using 3D prints for casting|
Thanks for the reply - I'm still impressed by the castings however they were done !
Presumably its easy enough to print out the pattern slightly larger to take shrinkage into account as well ?
Wrt to the castings - they look very clean and tidy. This is probably a silly question but I can't see any signs of risers or sprues on them - any idea on how they were cast ?
|Thread: Parting Off MEW225|
|I've seen a commercial one years ago on a stall at the MEE at Olympia. Definitely swan necked and also odd that it used a disc of ( presumably ) HSS with a segment cut out of it - not the usual long blade.|
I was tempted but the thought of sourcing replacement cutters put me off...
|Thread: Traction Engines in WW1|
|Now I know !|
|Watching the clip made me wonder if traction engines have differentials ...|
Do they ??
|Thread: Parting Off MEW225|
|I haven't thought about it too much ... but... I wonder if some of the 'angst' with parting off with a Myford is due to it being a plain lathe I.e. without prismatic guides ?|
Would the various resultant forces on the tool post when parting off be any different with or without them ?
|Also... a sharp tool !|
I used to sharpen my blades very crudely on a bench grinder - hand held as well...
Parting off become a lot less stressful when I started to grind them up properly !
|Thread: Rust Treatment|
|If you have a compressor, I'd use a small sandblasting gun. In my experience ( Lancia - need I say more ?! ), rust killers just slifhtly prolong the time for it to bubble through again - sandblasting kills it dead. It also gives a good finish for primer to adhere to. |
Unfortunately, it usually uncovers a lot more rust than you were expecting - and if you're a but too enthusiastic, can blow holes in rust weakened panels...
|Thread: Parting Off MEW225|
|....best option I've found is to just use a hacksaw.....|
|Thread: oiling the cross slide|
|I've sometimes thought about adding oiling points onto the cross slide of my Harrison which is similarly devoid of them.
Would it be a good idea to mill a narrow channel to spread the oil evenly and act as a reservoir - and would a 'diagonal' one be best to cover as much of the sliding surface as possible (without going right to the edge ) ?
Obviously I wouldn't want it any bigger than necessary to avoid increasing the wear on the remaining metal....|
W. Edited for spell check getting ideas of its own....

|Thread: Questions on an Electronics Expert|
|Wrt to 2 - someone with a bit of experience would get a fairly food idea on the type - and if a power tranny - the wattage or 'VA' just just by looking at it - a 50VA transformer for example, is pretty much the same size as any other 50VA one. The primary and secondary windings I would identify and quantify by using a meter and 'Variac' - that's probably a little too dangerous if you have limited experience with messing about with potentially lethal mains voltages.|
|Don't forget there's going to be a 0.7v drop across each diode....|
There's a very good freebie programme - Google 'PSU Designer'that can simulate simple power supply circuits.
|Thread: What did you do today? (2014)|
|Ate far too much !|
|Thread: Problem with Single Phase Hoover AC Motor|
|I seem to remember there was a previous post regarding a Hoover motor with perished rubber interior wiring so a rewire job may be on the cards as well to keep it safe !|
|Thread: Who might have made this?|
|I could have done with something like this a few days ago when adapting a light to take a GU10 bulb...|
A brief look with a rule gave the impression the bulb holder fixing screws where 12mm apart - the poor fit and a search on the net showed they should have been 12.1 !
|Thread: LEDs ... The Good, The Bad, and The Ugly|
|I feel your pain. I had a couple of expensive professional audio recorders trashed at work due to so called 'leak proof' batteries ozing nasties everywhere|
Even though they self discharge in about 6 months, I use Nimh rechargeables on everything of value these days at home !
Ps - scope pics of the led bulbs running of ac in my album !
Scope pics will be posted when I return to civilisation....
Briefly, both lights use MC34063 regulators. There's a lot more supply ripple on the 3 led one - but it does take more current at 500ma compared to the 60 led one at 365 ma. This was at 12v ac measured with a 'true RMS' digital meter.
Probably more to the point, the 60 led bulb has 2 x 470uF smoothing capacitors, the 3 led one only a single 220uF.
Not the thing you'd really be able to tell unless you pull or rather smash them open unfortunately !
