Thread: Model tug boat plans
29/11/2020 15:42:48

Take the plan to a copy shop and ask them to print it off twice full-size. I use our local one they are very helpful getting drawings to the sizes I want and not expensive.

Thread: What am I?
25/11/2020 16:31:19

I am with KWILL on this we used a local university engineering department and their final year students to design a piece of plastic extrusion downstream handling equipment as a project for them and we would pay for it to be built.

The build was started by a local engineering company that was our go to supply for this type of project. It proved to be very difficult to build even after checking by by the head of department. The project was abandoned as not viable to make as it needed a total redesign.

Thread: Level of qualifications in the UK
25/11/2020 16:21:36

I have done a lot of interviewing during my working life, I would always be wary of someone who was over qualified or their experience was greater than required for the vacant position. I learnt from experience that some of these people used the job as a stop gap until something better came along or were only going to stop long enough to fill a missing skill on their CV.

If I had to choose between someone over qualified or someone under qualified I would take the later smaller salary but we grow them to suit our industry and this would be then reflected in their salary.

Thread: What am I?
25/11/2020 07:49:57

According to my local ME club I am not a model engineer because I don’t make and run steam loco’s. But my father was a working clockmaker who made his living making clocks said I was an engineer.

Thread: Lathe Setup / Tests
09/11/2020 20:02:47

The Chuck looks tired and knocked about, have the jaws gone bell mouthed? so not gripping the bar very tightly. What type of insert are you using not many like taking 1/2 thou cuts unless it’s a sharp silver one for aluminium.

Thread: I'd like a simple plastic injection machine or designs
03/11/2020 09:23:58

I spent a long time in the plastics in my opinion you are wasting your time. In one of my laboratories we had a small simple injection moulder, made by a well known test equipment manufacturer for moulding tensile test samples what it produced was very inconsistent. You would get short shots voids etc in mouldings lucky to get one in ten that was any good. No good for test work. We tried to use it for polypropylene and high density polyethylene. The machine ended up in the scrap metal skip. It was replaced by a proper small injection moulder that made consistent test pieces, filled the hopper with plastic pressed the start button and left it to it.

Good luck with you your project it will be interesting and probably frustrating, injection moulding is a interesting process but not certainly not simple.

Thread: Two sides of a coin?
31/10/2020 21:15:39

I pretty much use M machine for all my metal requirements, always get good service and products. I like that you can buy metal of a known specification.

I have built the high speed marine steam engine, it’s a while ago but I don’t remember any problems with the build. It’s now in a boat with flash boiler it gets up and planes no problem at all.

Thread: Putting some grip (stippling) on an aluminium drive pulley.
17/10/2020 08:23:04

I found spiral flute taps worked better when I was doing the starting grove in steel flywheels for model boats.

Thread: Changes to Fusion 360 Terms
26/09/2020 07:52:01

Having just watched the video posted by Emgee I am going to stick with 360. I have found it hard work to get to the level I am at, I have no intention of starting again with another package.

if my little cnc mill runs a little slower I can spare the time it can also do things that I cannot do on a manual mill. I was considering giving the machine to my son but he’s now going to have to wait a little longer.

24/09/2020 19:25:45

When the water jet cutting has finish their will be very little of the steel left, I will post a picture of it when it’s cut.

24/09/2020 18:15:07

It’s for a 2.5cc tether car it should do 150mph needs to be rigid.

24/09/2020 17:36:12

Can anyone recommend a company that would cut out two model car chassis from 12mm thick mild steel 400mm long 60mm wide.

thanks

Thread: Scaling back forum activity

Barrie

i believe their is a need for a more broad church model engineering site, the existing ones are predominantly set in the past. My interests are fast more modern model engineering for cars boats and planes.

We now have a tether car track in the UK first one for around 50 years, we have only had two events Covid secure with a lot of interest in building cars which was once the domain of model engineers.

Thread: Steel stock for newbie ???
11/09/2020 06:04:15

I buy my metal from a company called M machine, they have a big range of material and it’s all sold by grade, I like to know what I am buying. Plus they are very helpful.
