|Thread: What Did You Do Today 2019|
Adams oiler was leaking on my ML7, (it's about fifty years old but appeared to be in excellent condition, apologies to other ML7 owners who will know what comes next!) would empty itself over two or three days. I had a good look at it, oil seemed to be leaking past the needle. I removed it from the machine, couldn't see any problem with it, I thought there might be some debris holding the needle off the seat. So it took it apart, I carefully examined the plastic bowl for cracks - nothing! I checked and cleaned the other parts and decided to reassemble. When I picked up the plastic bowl, it fell apart into four pieces, there were cracks radiating out from the hole in the top. It seems that removing the top nut allowed the bowl to change shape and crack. I still don't know why it was leaking but I don't suppose it matters now.
I'm now looking for some 30mm glass tube. Have you seen the price of small drip feed oilers?, 50ml ones are about £3.50 frim China, why are they asking £22.50 for 25ml ones?
|Thread: Dialect expressions|
Next week, next Tuesday etc. Means the week or day AFTER the next. Seems peculiar to Essex.
|Thread: New coffee maker - disgusting taste!|
|Thread: 5 Cylinder Rotary Air Engine|
I recall fizzy drinks bottles being used for on board CO2 tanks. Can't remember how much pressure they would take but it was a lot. Should be easy enough to pressure test a few bottles with a boiler test set.
|Thread: Crumbling Monkey Metal|
Reminded me of an engineering firm who made motor scooters in the late 50s. The handlebar bracket was a Mazak casting, the handlebars tended to fall off.
|Thread: What are they?|
It is a chamfer tool for round metal bar and threaded rod after cutting. Not a new idea, I had a similar item 50 years ago for use on wooden dowels.
|Thread: Ally Pally Exhibition advance tickets|
The internet is a golden opportunity for thieves, there was (is?) an almost identical copy of the government road tax renewal site. They rip you off for checking and submitting your road tax application, an unnecessary service and one which is deliberately intended to defraud. A lot of care is needed when dealing on the internet, make sure that the site you connect to is the site you actually want, search engines are just as likely to direct you to the people you want to avoid.
|Thread: The Workshop Progress Thread 2019|
I wouldn't mind getting it all wrong if my jobs turned out like that.
I like the drill jig, just what I need for my Clarkson.
Very nice work Joe!
|Thread: Using Hobs without a Hobbing Machine|
Isn't that the hat from the first Harry Potter film?
|Thread: Restoration and modifications to a Tom Senior light vertical mill|
Very nice work on the rack. You could probably buy a Bridgeport for the cost of the Tom Senior and get it ready made.
|Thread: Modern efficiency !!!!!!!!!|

I would go with photo etching, if they are a standard size you could do the artwork once and print them as needed.
|Thread: What material is it|
There are different grades of brass, some alloys are hard, some are ductile. It could be bronze. There are different grades of bronze. Sometimes difficult to tell one from the other. Daveb
|Thread: It's not rocket science|
|Thread: Pro’s and cons of owning an horizontal milling machine|
Most of the small bench mounted horizontal mills lack a backgear, that and the small motor makes them suitable for slitting saws and not much else. Daveb
|Thread: Help with Electrics on Emco FB-2 Milling head/table|
Emco motors are a bit peculiar and their schematics leave much to be desired. I've had two of the 4 speed milling heads, one 3 phase and one single phase. The single phase motor was actually a 3 phase delta connected motor with the line and neutral connected to (any) two of the wires and the capacitor connected between line or neutral (depending on which direction you want the motor to run) and the other wire. To confirm, use a multimeter to check the resistance between the 3 black wires, 1-2, 2-3, 1-3, they should all be the same. Daveb
|Thread: Mk1 Super 7 - What colours ?|
In the 60s/70s Myfords got a touch of flower power and produced some lathes in interesting colours. I particularly admired the bright orange. Hippies with lathes, whatever next? Daveb.
|Thread: What did you do Today 2018|
Started taking the motor off the Super7 to replace noisy bearing. Disconnected wiring, slackened screws and then found motor pulley was loose.
Nice and quiet now!
I get worse as I get older!
|Thread: Parallel Machine Files|
You need to search for PARALLEL MACHINE FILES. Good luck with that!
I had the same problem about 12 years ago, easier to get bull feathers! I eventually bought some from Federal file co in the USA for my bench machine (files, not feathers), they are a similar size to Swiss files. (I have an unused set of these PM if interested). I could not find any new or used files for my large filer so I bought a set of Swedish files (no particular reason for buying Swedish except the shop had a set in stock that looked as if it would do) 12", round, flat, square, tri, half round, etc. I cut off the non parallel parts and ground the ends to fit my machine, 60 degree point at bottom, 1" square tang at top to fit chuck, cuts on down stroke. Medium or coarse files are better, you will die of old age if you use fine files on these machines. If you haven't used a filing machine before, hold downs are essential if you value your fingertips.
Harold Hall designed a small filing machine some years ago, he made some suggestions on modifying standard files, should be some info on his website. Daveb
