Thread: Pratt Burnerd 4 jaw Chuck jaw alignment
20/10/2019 21:35:36

I think I would strip and clean the chuck and relubricate, also check the register is running true and remachine if necessary. I would eliminate all possibilities before attacking a lightly used chuck with a regrind.


Thread: angle plate

How about cylindrical squares then Tim?


Thread: Confession Time!
20/10/2019 09:44:11

Remember the days when you were working on a car engine and the tool you dropped usually appeared under the car? Now they fall into the under tray and a telescopic magnet with light is a big help to retrieve tool or whatever you dropped.


Thread: Is Model Engineering in Decline
19/10/2019 11:47:29

I had an interesting chat on the CNC4you stand which I don’t remember having been at a show before. In recent years there have been a few new entrants into the ME market and the shows provide a good chance to demonstrate their wares and knowledge. Younger entrants to ME are very likely to be very savvy with internet shopping and able to find much info and advice online. When Ketan withdrew Arceurrotrade from the show circuit he was brave enough to make his case on this forum and I think most people have great respect for his reasoning. The same reasons are likely to apply to most of the traders and hence we are seeing them fall away from shows and use the internet and their own showroom facilities to market their products. It’s funny how my experience of visiting on Thursday is different from some other posters, I joined the prepaid ticket queue at 9:37 and was through the doors at 10:02, I made a beeline for the balcony restaurant and there was no queue for my full English and coffee. Moving round the show was busy but not too bad, sometimes you have to wait for a gap to emerge to get to the front on some stalls but not a problem, after I came in from the outside exhibits and jet engine demo there was a strong haze of bacon smoke and a longish queue at the catering counter, the haze was unusual and I wonder if cooked food downstairs is new as I thought is was just a coffee cake and sandwich point in the past. We have already seen the demise of the Model engineer show so maybe the writing is on the wall for the others? There are still quite a lot of shows and I suspect the club run shows which strongly feature models and are run by a club with willing members can keep going as long as the members are prepared to make a considerable effort. I imagine the commercial shows will run until they start making a loss and I am sure they are thinking what to do to keep things going. Maybe shows will evolve and some of the criticism is that they are not like they used to be but if it was your first visit would you be happy with the experience. Times they are a changin’.


Thread: Tapping drill size
18/10/2019 23:23:54

I have been lucky enough to be gifted quite a lot of tooling from toolmakers and jig fitters who have retired, the taper shank drills seem to have a lot of 10.2, 8.3, 6.8,5.1 drills. I assume that these were the preferred tapping sizes used by chaps with hundreds of years of experience between them, even before I noticed this these were the sizes that I use.


Thread: VFD and screwcutting
15/10/2019 13:23:58

I would have a look at the braking features before making a decision on a VFD. A short ramp may be enough to give you what you need but some drives can use DC injection type braking which can be quite brutal. Some drives will need an external resistor to use the shortest ramps. I think that the ML 10 will probably only need the standard drive to give you the performance you want as it doesn’t have a large inertia to control. If you don’t mind fiddling then you could probably shorten the ramp at low speeds but it may trip with a heavy job or fast speed.


Thread: An interesting repair to an Hour Wheel
13/10/2019 13:32:19

I love a bit of alternative engineering, I have used it myself on many occasions. It is amazing what you can do with a few bits and pieces that are laying around or can be repurposed..


Thread: Plinth size?
13/10/2019 11:19:33

I suffer a similar disability with art and proportion but I think we all know when something looks right. I expect someone will have the answer you seek but otherwise I think I would try a few mockups and hope that the when it looks right it is right moment occurs.


Thread: Inverter reset?
12/10/2019 14:12:37

It’s possible parameter 50 set to 8 may define input X1 as a reset if that inverter is the same as the one I have just read about.


Thread: What is this called?
12/10/2019 14:07:26

That’s a good spot Bill, looks like Iain is sorted.


Thread: Inverter reset?
12/10/2019 13:22:17

Removing and restoring power will often reset faults. It’s possible that one of the drive parameters will also clear the fault. Check there is not a reset input that you have not wired.

Try searching for window keeps.


Thread: Cast iron cabinet theft
12/10/2019 11:02:21

Metal thieves are as bold as brass, during the night they pulled a mile of phone cable out of the ducts and cut the whole village off the internet and phone network. It took the best part of 2 weeks to repair the damage to the ducts and replace the cable. They must have had a buyer to go to that much trouble.


Thread: Changing internet providers
12/10/2019 00:25:49

I think you have to review what your total usage is going to need. When my son and his girlfriend were in residence then we could be supplying him on a game her on social media, my wife streaming a tv catch-up and me on YouTube. There is no point in buying something you don’t need or use. A reasonably fast connection does make surfing the Internet a more satisfying experience but depending on what you are doing the law of diminishing returns does kick in and a 1Gb connection will not greatly improve a solo user experience, of course we don’t want to go back to a 56kb dial up connection as the much more complex sites need more horsepower to provide a satisfactory performance.


Thread: diameter calculation

Obviously as a Myford user working to ten decimal places is normal practicewink

Thread: Telescopic bore gauges
10/10/2019 23:28:35

I see Chronos list them by the mysterious Dasqua, does anyone have experience of this brand?

Thread: What is the way to put these holes in the right place?
10/10/2019 12:22:01


A gauge could be made like this, if the round bar is made dia.14.14mm then the face of the bar as indicated will be 10mm from the apex of the mitre, use you favourite edge finder to locate then position to drill and tap.


Thread: Triangular Screws

I suspect Neil that you have encountered them without noticing, they are widely used on vehicles.
