Hi, Thre are center drills, 60 degrees inclusive, spoting drill 90 degrees inclusive and then either stubb drills ( short length ) and jobber drills. The centering ones ( the ones with two tips ) are divided into straight profile ones such as the one in your link and the bell profile ones...

Hi Nick, I have only been in this hobby for less than 2 years, that is exactly what I taught myself to do as soon as I learned that to turn a 1.5 mm shaft out of 2 mm stock is not going to work, that seems a long time ago. I rather use a 5 or 6 mm free cutting stock and turn in one pass, there...

Hi, May I ask what is the reason you wish to convert an antique lathe into a CNC machine? These things were designed to work as per normal, I think that you will always have issues with repeatability with old hardware such as this. In any case one way to reduce the backlash is to install a...

Hi, This is not what you want to hear but I strongly advise you not to run any IC engine of anysort indoors, particularly a flat. It is just too dagerous because of fire risk and the fumes. Try and run these outside to make sure that they run and if anything goes wrong then atleast there is no...

Hi Robin, I hadn't noticed the telephone no code before, 0161 is the code for Manchester where I am, and their phone no starting with 4 means they are somewhere is south Manchester, Stockport area perhaps, macc models are based in Macclesfield, south of stockport ( about 20 minutes drive...

Hi, I live in the UK but got this from the US. http://www.ebay.co.uk/itm/1-THICK-CARBON-GRAPHITE-ROD-1-x-12-LONG-MIXING-STIRRING-CARBON-ROD-/221005884903?pt=LH_DefaultDomain_0&hash=item3374fa2de7 A.G

Hi, I have just tried to log in to my account with Macc Models and I can't log into my account. They have also revamped their site and these maybe related. A.G

Hi, I have turned the valves for a Webster engine and they are simillar to yours. I found that it was better to start with a large diameter stock and turn in one pass, you can then use a fine emery cloth to polish the valves or take out a small amount taper . A large diameter stock will...

Hi, Macc models have a good range of copper tubing for boilers and are good to deal with. I have no association with them but the service has been good. I have also dealt with M machines and college engineering suppllies and these are all good pro traders. A.G

If you have a small drill press, find the center of the wheel, spot, center drill, drill undersize and ream to size . Then make an arbor just undersize to the bore of the wheel making sure that it is a tight fit with a small shoulder at the back for the wheel to butt against, thread the front...

Hi, I am with Jasonb, if you can redesign the engine go with Oilite, it is better than bronze and will last a life time. Cast iron is the last choice, for low rpm engines but it need to be the right type, SG I think but I am not 100% sure. A.G

Hi Geoff, Great looking and great running engine, thanks for sharing. Regards, A.G

Hi and welcome, A.G , NW ( Manchester ) UK

Hi, I really like My ML7 too, I am getting it sorted out little by little. There is something fudamentally right and organic about the feel of the lathe. Once it is sorted it will be great tool again. Regards, A.G

Hi, A simple stuart or a Stuart 10v (ambitious)or a small PMI machine should be fine if your skill level is up to it. If you have not made any engines before it may be prudent to start on a bar stock engine first untill you get the confidence. With castings there is very little chance of...

Hi mark, That is about £600.00 give or take a few buck or quid. That is enough for a new but bare bone Super X2 mill with Dc motor and belt drive over here in the UK. You either need to up the budget or have to look at the used market, that much money should get you a good deal. As for tooling...

Hi, I think that you need to understand how this system works. Most of these machines are made in China, as you know, in two or 3 large factories and then painted , labeled up and even specced up for different destinations in batches, so there is always a shipment period of at least three...

Hi Abby, I have no doubt you are correct, my main work horse for anything from 1/16"and up tp 2"is the Taig lathe, I do some work on the Sherline and swap around, I have not done much on the C1 for quite a while. The Pultra lathe shown in your link is a marvelous piece of precision engineering...

I don't think there is anything wrong there. It is just that is rather inconvenient to remember how much you have turned the wheel. The best ratio for me and the most poular is 72, which means that each turn is 5 degrees, therfore if the dial is marked in 50 divisions, easy to do and remember...

Hi, If oyu can afford a Gecko and the matching motors go for it, it is about the best for the money, if you have it. It is not necessarry for the motor to pull 48 Volts for max torque. If you connect the poles in series the motor actually gives its max torque at the lower speed end and with...
