|Thread: Angel Eyes.|
Years ago I got hold of some BMW 'angel eyes' which were 'pre' LED and needed a driver to light them up. They woe really bright compared to LED's at the time.
Battery charger power supplies always run above stated voltages but drop closer to stated voltage when connected to their original battery with 'correct' internal resistance. The exception will be chargers for lead acid batteries which will always run closer to 14v
|Thread: Setting up mill|
Check the column to base bolts are torqued properly.
It's possible to adjust tram on a 'non adjustable' mill by changing torque values (if that doesn't work you may also have to shim different quadrants of base)
I got my mill drill with an 'inspection chart' that was pretty worthless but eventually got it near perfect by thinking about which bolts to tighten and loosen. The various sections of cast iron will distort tiny amounts but can be set pretty accurate (less than0.01mm over 8" swing)
Sorry to be swapping imperial / metric but I was brought up on imperial measurments and trained as metric was being introduced so have little trouble switching between the two(I'm sure there are plenty of us 'old duffer's' who do the same?)
Just noticed the post directly above mentions the samwe thing about column bolts but didn't see it while I was typing (and running around doing 'other stuff)

|Thread: Milling cutters choice|
For aluminium I've found un-coated solid carbide are best.
The only problem I've come across is I can't run them fast enough in small diameters.
I did adapt a 'trim router' to fit lathe tool post but it's fixed speed (27,000rpm) worked OK even on 1/2" thick steel (A36, structural steel, don't know UK equivalent, probably EN8 or similar?)
Cutter was 2.5mm dia and 'mostly OK' (not overheated or chipped) after about 35" of cutting.
It was actually easiest 'trepanning' I've ever done
|Thread: Reversing Motor|
I had the same problem with lathe motor.
The original motor had two capacitors, both 'starting caps' one for forward one for reverse.
The motor I replaced it with only has single cap so needs a different reversing switch with an extra set of contacts.
You have to reverse the field windings to get motor to start in the opposite direction
At present, I haven't changed switch so only have forward rotation as it isn't possible to bridge various contacts in multi switch to obtain reverse
|Thread: BA threads|
I always thought they were Continental and Japanese industry standards. Continental (French/German) 8mm bolts have 13mm head and JIS have 12mm head
It's been 'common knowledge' in the motorcycle industry since the ISO standard was changed in 1965 (ish) Now, all metric threads will interchange even if bolt head size is different. Anyone who has restored a pre-1965 'import' (generally Japanese or German) knows there are differences in thread design
|Thread: Loctite made in China?|
Generally, the problem isn't 'Made in China' but quality control by managers. (line workers have no say in what they are assembling)
Personally, I wouldn't be able to continue my hobby if it wasn't for 'Made in China'
The labor costs are incredibly low there compared to any industrialised country (same in India although materials can be inferior to Chinese stuff sometimes)
I would like to be able to purchase better quality materials and machines, but, unless your going 'full industrial' most modern stuff is pretty lightweight and cheaply made compared to 1970's and earlier machinery but still has a premium price out of my range.
|Thread: Adhesive for foam insulation|
As with everything nowadays, there is far more to learn than you ever wanted .
Interesting topic though.
I'm going to use paintable expanding foam in a can to cut down the rattling from belt cover on mill/drill
|Thread: Jacobs Chuck|
I'm glad you mentioned thar, I think I may actually have a set but had completely forgotten about them.
Now all I have to do is remember where I put them ~20+ years ago. Probably still hanging on a nail in garage (only problem with that, garage in Wales, I'm in Florida)
I won't ask my brother to look though, he'll probably sell them
|Thread: M2 x 2mm brass grub screws - do they exist?|
|Thread: Bronze balls in place of steel balls in a Land Rover|
For the OP I would say use oversize hardened balls and a full synthetic high pressure lubricant.
For everyone else, insurance is probably the biggest legalisedf theft there is.
I obtained a Florida insurance licence,
There are a lot of con-men in insurance industry, the ''manager ' who convinced me was one of them. It's a totally disgusting immoral industr yfull of very hypocritical greedy people some who actually believe they are 'doing you a favour'
I refused to sell the overpriced products and was literally marched out the door..
Since then I've been approached by numerous companies, many even more unethical although still staying within the boundaries of 'legal'.
I'm fully aware there is insurance fraud, but, majority of people really are pretty honest and insurance companies spend far more on lawyers fighting cases to avoid paying money to genuine claims with lawmakers supporting them. Just take a look at insurance company reserves and profits, most are in the several billion range. That was not what insurance was meant to be.
I did some research many years ago,
Richard Price from South Wales (Llangeinor actually) was a vicar who 'invented' actuary tables (risk of loss) He was also a friend of Benjamin Franklin and an 'honorary' American)
The State licence exam pass rate is less than 20% so it shows the caliber of people involved 'over here' (only 17% passed first time in my group, yes, I was one of them who passed)
Guess that's enough of a rant, almost 6 years on I'm still disgusted by the things I found out.
|Thread: Jacobs Chuck|
I've got a couple of Jacobs chucks that are a bit 'sticky' in places so I think I'll have a go at fixing them. It won't be a big loss to me if they are scrap as I got most of them 'free' when buying other stuff (the box of junk that often goes with used machinery)
|Thread: 1-2-3 Block Clamping|
Even though I'm in the USA I also find it annoying as I've mainly worked on Japanese motorcycles since I started 'playing' with bikes in 1968.
'Everything' I have is metric but at least UNC is easily available over here. I usually end up 'converting' to metric threads as it's a real pain having multiple sets of tools to work on stuff. I have very few 'imperial' taps and dies but all sorts of odd size metric (7x0.5, etc)
|Thread: Micro rivets|
For such a beautifully made model it would be a great shame to bodge it.
When I was training (1975~) I had to make 100+ rivets for instructor from 1/8" stainless steel welding rod.
Heads were 1/16", I forget shank size but remember they were 3/8" total length. I think I lost almost as many in the swarf tray as I made. (his hobby was clock making and obviously he didn't want to make all the rivets, having a bunch of students able to do it for him)
I wasn't bothered though as it did get me a good grade for 'projects completed'. (or something?)
The right thing to do would be dismantle sections and re-build them with new rivets.
Copper isn't the best idea as it has a galvanic interaction with aluminium (stainless steel has similar reaction with aluminium)
Personally, I would make a bunch of rivets from 6061 then modify a 'Mole' grips to set them (get a cheap copy, remove jaws and grind flat, ball end mill for head and set shank) Just squeezing rivets would make re-assembly pretty quick ,particularly if you 'glue' parts and sub assemblies together first
|Thread: 1-2-3 Block Clamping|
I've got several sets of 1x2x3 blocks of various qualities, some 'perfect' exact size and others a little undersize after being ground square. It's a neat idea which I had forgotten about as I don't use them very often.
video was too long but was for 'beginners' so I guess he had to explain why he was doing things?
I would have made some double diameter studs as well for the times you want blocks locked together in a larger size (oh, I already did )
Various length studs are easy to make from ordinary bolts, cut the head, off turn shank to diameter and thread it. (heads are usually forged so much tougher than shanks)
|Thread: Die query?|
All the information was available in the free 'handbook' pages published in the 90's in MEW.
I still have mine and reference it more frequently than I probably should to make comments on You Tube
|Thread: Motorcycle General Discussion|
I had a similar experience in the 80's when I was doing Enduro's.
Andre Zembruski and Geraint Jones (World Enduro champion at the time) set up a course somewhere in mid Wales with a 'rather steep' downhill. They put a checkpoint at the top so people would heve to stop and be warned.
I was riding same minute as my buddy Chris. (he won 250 Clubman championship 1980 or 81?) He went first, stopped and looked down then rolled over the edge. I thought 'pussy' and hit it as about 20mph in second gear. He says I passed him about 8ft in the air, upside down. I only remember 'fish tailing a couple of hundred yards bouncing from one sheep track to the next then seeing a cut down tree about 6ft diameter in front of me.
When I woke up, a kid was standing over me , first thing he said was 'why did you crash, we thought you were going to make it' Apparently I did make it almost all the way down but paniced when I saw tree, got sideways and high sided.
Bike was pretty bent up, the chromoly bars had finally bent (been on about 6 bikes previously) front wheel was hitting forks both sides and I was hurting like hell.
Bike started OK so I got instructions how to get back to start. Trying to wheelie over a bank, I found I had a bunch of broken ribs and almost crashed with the pain.
Found out later I caused a major panic, 4 ambulances were out looking for me, course marshals couldn't find me, they thought I was dead in a ditch somewhere but I was already packed up and on my way home (luckily girlfriend at the time was driving, she and a couple of other people loaded biker into van, no way I could do it) It was my worst crash ever but didn't put me off, later I got a 490 Maico (that tried to kill me many times)
That sounds like advice from the 1900's~1920's for normal highwayas it mentions roads coming in at an angle? (rather thasn tracks you would find off road)
|Thread: Shipping delays and costs|
I think Covid has also had a lot to do with shipping delays for anything that can't be sorted by robots. Even internal mailing systems are about 4~5 times longer than was normal 2 years ago.
I ordered some parts from Germany, contacted seller after a few weeks and was told things are taking 2~3 weeks inside the country where it used to be 2~3 days.
I've had parcels held up in local distribution centre for 12~20 days (and that's only about 4 miles away)
Side effects from Covid are wider ranging than most people realise.
Bulk shipping is still cheapest way to move large quantities of 'stuff' long distances,.
Diesel ship engines are the most fuel efficient in the world (above 38% compared to about 30% for normal petrol and a little over 10% for external combustion (steam engines)

|Thread: Motorcycle General Discussion|
Thanks for the link,
I had no idea this stuff was available online
That is something I've only ever seen on a Villiers engine race bike probably 50 years ago? Wasn't 'mine and never got into it.
My father would have known but he's been gone since 2004.
