1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    As above. Please keep us posted.
    I've been doing some milling... just lightweight stuff in aluminium. A CNC mill is out of the question but I wonder if this router would do the job using 6mm end mills. Does it take 6mm/ 1/4" collet?

    Yes, the spindle is ER11, which I think is collets up to 7mm. I have some collets in that size anyway, this arrived the other day from China, 6mm, 3 quid, it’s mint!

    Yes, I use cheap Chinese mills too - various shank sizes: 6/8/10/12mm but no 7mm. Fine for ally and brass :thumb:... ok for mild steel too but I've not done much milling of steel so can't say how well they would last. If I had to buy more in 7mm it's peanuts in the overall scheme of things.

    squib,
    Is 65mm the thickness of the work you can clear?

    I believe so, but it will depend on the length of the cutting tool. I’ll check later.

    @Sarge , see pic below. There’s 85mm between the bed and the underside of the X axis carriage. You’ll also see the motor will lift in the clamp, so I reckon you’ll get a fair old chunk in there. You’ll be limited by the Z Avis travel though.

    Back to business though, and I’ve had a change of plan. The first thing I want to do with this is a shedload of carving out pockets in bamboo. It occurred to me today that it will actually be quicker if I use the router more like a duplicator. To that end I’ve striped all the wiring and drive gear from the chassis. Now the X&Y are free to go anywhere, and I’ve left the stepper and screw on the Z axis so I can manually control cutter depth. Everything feels pretty rigid as it slides about on its linear bearings.

    I’ve ordered a new motor mount that will take a heavier duty 1/4” x 65mm diameter laminate trimmer, that will fix in place here, where I have removed the existing smaller 400w DC motor:

    For the duplicator side, I’ll mount something that will follow the template over on this side. I can use existing holes etc so nothing needs drilling.

    Before I get that lot running though I need better dust extraction, and there’s a 2.2kw centrifugal fan at work going begging. I ordered an inverter for it today, £62 delivered !

    Thanks for that, I'm looking at options for engraving receivers and other component parts after this new ruling on serialising came out, this is one of the options with many other uses :thumb:

    Been doing a bit more farting about with this.
    First job is to fit a bigger motor, so made an adapter plate to take a bigger mount:

    Now the larger mount and new motor

    Last thing today, the start of a vacuum fixture. I had to be resourceful with the external seal, the wife is now -1 of her click seal food tubs. :thumb:
    Get reasonable results just with a vacuum cleaner, got a proper pump turning up next week that should be good for -800mbar.
