Hi, A two flute cutter is a slot drill, a 4 flute cutter is an end mill you can plunge cut with a slot drill, as well as a center cutting 4 flute end mill but not all end mills are center cutting. More importantly, if you wish to plunge and cut a slot then only use a 2 flute, slot...

HI, Try RDG tools, if you google them its easy to find. They have at the moment a couple of sizes of cast iron flywheel castings , I think there is a 4"wheel for about £10.00 or there abouts. They seem to be rough castings that you'd have to machine but at this price theses are worth having a...

Hi Speedy, Besides the obvious a machine reamer has a very short lead taper at the head compared to a hand reamer, think of this as a bottoming tap V a taper tap, therefore it is the suitable for reaming blind holes such as a cylinder in model engineering. A hand reamer has a very long lead...

Hi, The only example that I have seen is on a SIEG C1 microlathe that has a captive lead screw, the details are on the C1 users group at Yahoo. I guess that maybe something simillar could be done for a SIEG mill. Regards, A.G

Hi, Use an HSS tool with a very sharp nose or one with a very small tip radius. Turn the large diameter first to correct size, then turn the small diameter to correct size and length, on the last pass once you have reached the required length, lock the saddle in position and bring the tool...

Hi Speedy, I too have a Taig lathe and a variable speed dc motor on it ( Sherline ). Have you got a hand reamer or a machine reamer? If it is a hand reamer then it is self explanatory just use tons of lubricant and take slow and steady, if it is a machine reamer then I don't think the...

Hi, I would be cautious as not to use a harder material as a piston in a soft cylinder. Replacing a piston is a lot easier than machining a new cylinder. If you are going to operate the engine with steam then I would stay away from cast iron and steel, with compressed air there is no...

Hi, Good luck, just one point, if you are going to use the chuck then try not to rotate the rod while pulling it out and allowing the jaws to clamp on the same spot, this will decrease the chance of the chuck run out ruining the concentricity of the chuck and work piece you are turning...

Hi, If you have drill press or a even bench mounted mini drill , center the die under thr drill and just drill the bits off using small drills, 1/16" would do for 8 BA. Regards, A.G

Hi, 66 mm length of a 5 mm bar is a tricky one. If you have a collet holder use it in preferrance to the chuck. I wouldn't bother with center drilling at all, it weakens the rod even more. There are a couple of methodes you could use. 1- Allow only 10mm of the rod to extend beyond the...

Hi, If you want a top quality small boring bar to do small holes with, 1/4" and upwards take a look at these. They should have their own dedicated tool holder but I have used them very successfully by clamping them onto the tool post as normal or making a brass sleeve to hold them in a QCTP...

Thanks very much Brian , I was just worried that the old loctite wouldn't stand up to the temp so thanks for clearing this up. Many thanks and regards. A.G

Hi Brian, Just one silly question , how did you get the exhaust pipe fixed in? Is it press fit or glued in somehow? Regards, A.G

Hi Brian, Thank you for posting the link. Regards, A.G

Hi Brian, Thank you for your reply, I inted using a traxxas pro.15 carb and Coleman fuel, so I guess that the one way valve is not required. Best Regards, A.G

Hi, Yes you need a milling machine as well as the lathe to do things such as engineering and model making , etc. The mill that compliments your lathe and may save you some tooling expenses is the Sieg X2 high torque model, this is the one with the belt drive and DC brushless motor, but there...

Hi, I am at the last stages of building this engine and I came across a thread stating that this engine needs a one way valve system such as the one designed by Jan Ridders. There is no mention of this in the plans. Does anyone know if this valve is necessary and if so how to build one or at...

Good evening Tin, Thank you for your reply and advice once again, I understand what you are saying but my problem is that my hands are not vey steady , so perhaps I should make a jig to sort of rotate the bit around and achieve the radius. Do you think that is a feasible option? My grinder has...

Hi, I need advice as to how properly grind a 1/4" round nose lathe tool . I have a small belt- rotary snder and an 8" run of the mill grinder. I can grind left and right hand tools quite well now particularly using the belt sander but have no idea as how to grind a round nose properly. I will...

Hi, Thanks to all who replied with their tips and help. No doubt I shall be back for more advice once the build gets going. I have already ordered the 2.5" Dia 6082 and some 2014 for the rods and cylinders. Regards, A.G
