    Torch for silver solder.

    The torch handle has two controls - main gas flow and pilot flow - so you can adjust according to the burner fitted. For example, if I'm using the needle flame burner, I'll probably just use the pilot control as it is a bit more delicate and there's no real point in a separate pilot flame. For...

    Torch for silver solder.

    Getting back to the original question! TerryD pointed to the basic Sievert torch, which is fine, but particularly if you are going to be using the larger burners, the 3488 handle is worth considering. The separate pilot control and trigger for main gas flow is useful to avoid having to hang the...

    Torch for silver solder.

    To clear up any misunderstanding - my problem was silver-soldering a machined phosphor-bronze component to another brass component. I just could not get the SS to flow on to the bronze. I wasn't using phosphorus-bearing rods - as you say, a different kettle of fish. The problem with learning...

    Torch for silver solder.

    The world seems divided into two - those who insist that only the old and generally banned Cd-bearing solders ("the only way to get the stuff to flow into a joint properly") should be used and those who are happy with modern, widely-available, non-Cd silver solders. Personally, I've used Easiflo...

    Looking for a good way to learn solidworks

    At least the software and all its data are kept on your local machine. At worst, even if you never get another update, you have something that can read what you have done to date and write it out in an industry-standard format. That puts you in a better place than some of the other options. Even...

    Looking for a good way to learn solidworks

    Try this link. Definitely says free non-expiring licence. Takes more learning than F360 but looks more powerful once you get there. I'm still using F360 for day-to-day purposes but trying to get up to speed with SE for the next stage of my current project.

    What to charge to thread a rod

    I mentioned earlier that my local area rate of exchange is the bottle of wine. I handed over the house nameplate I have just made for a neighbour earlier this morning. He knocked on the door just now and gave me a half-box (6 bottles) of wine - look like decent ones, too! I did complain that it...

    What to charge to thread a rod

    Standard rate of exchange round here (South Devon, UK) is a bottle of red wine. Two bottles if it's a big job... I'm in the middle of cutting a house sign for a neighbour's new house which might be a two-bottle job as it involves more work than usual (had to 3D scan a relief image from an...

    Carburetor with accelerator pump

    I have come across "submerged jet" carburettors which avoided the need for an accelerator pump by putting the main jet at the bottom of a small well which fed the carburettor venturi. The idea was that in steady running, the jet metered the fuel flow correctly but a sudden throttle opening would...

    Squaring off the bottom of a blind hole

    I gave up about the time I discovered that on one side of the pond you pay a bill with a cheque and on the other side, a check with a bill. :) I suspect that even in the UK these days, the term "slot drill" is used more amongst model engineers than industrial users, certainly going by the...

    D1-4 cam lock spindle??

    What there was, was a whole lot of mucky grease that had probably been congealing for the last 50 years! Mine has allen bolts holding things together, so I took those out. Couldn't see a spring in the first one; in fact, there only seemed to be two springs so when one went missing I don't know...

    D1-4 cam lock spindle??

    I live in a small village in South Devon, which sometimes feels like being slightly to the West of the edge of civilisation. But our broadband is lots faster than when we lived in Hampshire and the postal service is spot on! I'm currently trying to install the new cams. Or, more specifically...

    Autodesk Fusion 360 or other free software?

    Haven't actually done anything with it yet but as far as I can there is no licence expiry date (i.e. it is unlimited time) and I don't think that it is locked to a specific machine. I have the "Community" edition as I struggled to see differences between two or three offerings. But given that it...

    D1-4 cam lock spindle??

    D1-4 cams ordered yesterday morning, left on the doorstep this morning. Not bad. Blighty - I was looking again at that chunk of steel you are using. That's a mighty big bore down the spindle! My Smart and Brown is somewhat restricted as it is only 38mm clearance but it does have a 5C collet...

    Autodesk Fusion 360 or other free software?

    I've just installed the free version of SolidEdge 3D. Be interesting to see what it's like compared to F360.

    D1-4 cam lock spindle??

    Many thanks for that. I know that the bigger Warco machines use D1-4 but hadn't thought of going to them for spares. I'll give them a call. Edit - just called them and they will be in the post shortly, "It's funny," said the guy on the phone, "But someone else rang and bought a set of three...

    Autodesk Fusion 360 or other free software?

    Difference between hobby and business? Closest I get to "earning" from my hobby is helping a friend with something and getting a bottle or two of decent wine as payment! Common payment method in this part of the world... I doubt that any of the "making" things I do would earn me anything like a...

    Autodesk Fusion 360 or other free software?

    It's an interesting question - reminds me of that old one that goes something like, "At your usual hourly rate, what's the smallest denomination note/bill/coin it's worth bending down to pick up?" As a model engineer, I'm not sure that I can value my time in any objective sense. I make things...

    D1-4 cam lock spindle??

    I have a D1-4 nose on my own lathe, and could do with replacing the cams in the spindle nose - as they often appear to do after years of misuse, the square key holes are cracking and although usable I would like to replace them. I'm guessing that Blighty might also want to buy in things like...

    Autodesk Fusion 360 or other free software?

    I should have added that the code generated for each individual toolpath includes both the initial G0 to move it to the start of the cut and finishes with a G28 which will bring the tool back to (usually) the toolchange position. At least, that's the way my G28 position is defined and I think...
