|Thread: Thread Lock|
Because of limited shelf life I buy little tubes from Halfords. I use it as thread lock and bearing lock/seal, red in colour and can be undone with a bit of effort. From memory around £3.50 I shall be buying some more in the next day or so as I have just run out.
|Thread: Hacksaw blades|
The yellow Starrett and blue Eclipse blades have both been poor over the last few months. I tend to buy 10 at a time so stuck with them if poor quality. My "Donkey" power hacksaw uses Eclipse blades that last well.
The same question from me. I prefer "All hard" blades finding they cut better/straighter and last longer than the flexible ones. Like old school my last few batches have been poor.
|Thread: What milling machine to buy|
Hi Bob, best give a general location for advice on metal purchase. Good luck in finding the right mill, you will enjoy using it. Chris.
|Thread: lathe chuck key hex|
If you are close enough to me I will make you one. No charge.
|Thread: 120mm diameter Delrin machining problem.|
Your biggest trouble drilling Delrin is the drill snatching, keep the tailstock lock on a bit to prevent the drill pulling in.
Good luck with getting it to size, I find that I can measure the stuff correctly and hours later the sizes are all over the place.
|Thread: hello all............|
Welcome LC. I am a newbie only recently joined after lurking for a while. Bikes are what I do; Pre war stuff for myself and lots of stuff for old bikes and café racers for others.
|Thread: bridgeport mill table feed wiring diagram with erskin pd/1114/01/b control unit|
Thanks Clive, I will wait until my auto electrician mate is over to check it for me. These things go over my head !
Clive, I have wired the Bridgeport traverse to the 0/220 tapping on the transformer and it briefly worked. After a very short time the motor started smoking and stopped. Removing the brushes revealed oil contamination so I have stripped and cleaned the motor, it will still not run but we are on the right track. Time to get my mate over with his AVO and see what is going on. Chris.
|Thread: Off center groove|
As suggested I have done similar on a rotary table but only for grease grooves. The maths get a bit involved but in my case for grease to travel it was not fussy.
|Thread: A request|
In my short time on the board I have never failed to understand any postings. My youngest Daughter edits and writes books; that is what she does well. Just do not ask here to do maths..... What I am saying is we all have different strengths and should not be critical of others. If you can't read it don't bother.
|Thread: J&S 540 help|
I have operated J&S 540 and 1400 machines for 50 years and never found the need to balance wheels even in a high precision tool room. We set the three weights at 120 degrees mounted the wheel to the arbour and fully dressed the wheel all over. We did have the balancing kit but after dressing never had to alter anything, we had 11 1400 machines and 4 540s each had 10 or more wheel arbours to leave wheels mounted up as much as possible. We used optidress wheel forming and work was checked by shadograph at up to 100 to 1. All in one of the top tool rooms in the UK.
|Thread: Phase converter / inverter|
My 2 pennorth, and I profess to no nothing about the workings of electricity. I have a 3HP lathe with a motor that was not 240/440 and a 2HP Bridgeport that is 220/420 (voltages from memory) For cost reasons I bought a Transwave static inverter/converter and had Transwave come out to connect up for me. The lathe was and still is happy running from the set up but the mill would stop after a short time. Transwaves answer was to change to a rotary converter. To costly for me as the static job had cost £400. A friend suggested a cheap Chinese VFD for around £90 wired it up for me and the mill runs perfectly. Recent information from this board and I have the traverse working from 220 volts as well. I would buy the cheap inverter again when I add more machines to the workshop. I would need help in setting them up due to the "Chinglish" instructions.
|Thread: Tools for turning between centres|
Kit, I would buy the new centre. There is no way of knowing what work or abuse a used one has had until you use it. I doubt if you will do enough work to wear the new one out.
|Thread: Endmill grinding - looking for a cheap option|
When I was at work there where lots of local cutter grinding companies, most often one or two man outfits. With the rise of China and the demise of UK tool making and general engineering sadly most have shut their doors. Couple this with the lower cost of carbide as CNC mills need it more and regrinding of HSS is hard to get done. I have a friend with a cutter grinder who will let me use his machine but these kind of people are few and far between for most folk.
Malc, where are you located ? Someone may be able to do a few for you occasionally.
|Thread: Numerical machining - before CNC|
Thanks for that, makes my mould making apprenticeship seem a little boring. I did get to operate the same jig boring machine though. Chris.
|Thread: Tools for turning between centres|
If you do buy a "Live" or as I call them "Running" centre, consider one with an extended nose length. It will save having to move the compound slide around to about 30 degrees to get to the end of the work on some occasions.
|Thread: 1935 Austin Seven Ruby ARQ|
What an interesting thread, it has been a long time since I ran a Severn (Swopped it for a Lea Francis) However just a thought on the bushes, I am making lots of bushes for folk out of glass or carbon filled PTFE self lubricating and impervious to water (OK the shaft wont be) Most of my work is for motorcycles and football pitch ground keeping stuff. Re bituminous paint, is it due to the new stuff being water based ?
|Thread: Setting up a long bar for between centres turning|
Iain, give us a clue on location, some of us have large machinery if you run in to trouble. I hate to see projects stall for wont of asking for a bit of help; credit to you for trying and coming up with a design. Is it for a wood lathe ?
