Hi, I seem to have lost the ability to load the site on to my IE9 browser, it started last night and I constantly get the message that HMEM has stopped responding and would I want to recover the page and then nothing. Right now I am using Safari to load the HMEM and it seems to be lot faster...

Hi, Happy new year to you all, wish you all a healthy, prosperous and peacful new year. Does any one have plans for a small boring head that I could build to use on my Taig or Sherline mills? I have the Sherline boring head but I find it difficult to work with and there is quite a bit of...

Hi, I live in the UK, anything decent costs an arm and a leg, a 12" Chinese made DRO- scale costs about £45.00, the Mitutoyo about £180.00. I managed to get a brand new Absolute Digimatic caliper for less than £60.00, the used ones are going for about £35.00~£40.00 , the Chinese calipers costs...

Hi Jim, Unfortunately this what I experinced with the cheap import digital calipers. The repeatabilty was just not there, they specify this in their charts at plus or minus 0.02 mm which is not good enough for critical work. I found that I get better precision with the Mitutoyo brand but then...

Hi , You have my sympathy, my work shop is in my loft but all my machines are small, Taig, sherline and a sieg X1 . A couple of months ago I bought a Myford Ml7 of 1949 vintage and due weight and size I had to put it in my garage that has a metal roof with tons of gaps. It is always like...

Hi, First machine the rim of the flywheel on the lathe and bore the crank hole, Then assuming that your rotary table is trammed on teh mill use a dti with n entesion arm of some sort to indicate the flywheel aroun its rim or use the crank hole. Make sure that the flywheel is true to the...

Hi , Do the 30 degree slot as the op. If this is a one off you could even file it. If you have a milling machine then you can tilt the part to the correct angle and then mill it or tilt the coloumn of milling machine to the correct angle and do the job. Regards, A.G

Hi and greetings to all, Just wish to express my thanks to all of you for your help. Regards, A.G

Hi Dave, Merry Xmas, I will certainly do as advised. I need to gauge how tight is tight with regards to the mounting screws. Many thanks and regards, A.G

Hi LongBoy, The ones that I have ordered from ebay are Pyrex, 18, 16 and 20 mm nomoinal sizes. I have a question though about the method of cutting these tubes. Would the scratch and heat method work for Pyrex tubes? Regards, A.G

Hi Stan, Many thanks for your tips, I have now got the crank to go around smoothely and it is a better fit in the bronze bushings. Will lap the air chamber next to bring it to touch with the valve. I connected it to my dimunitive air compressor and it does go around a few times before the air...

There was a thread and a reply from Jan, he said that the dimensions of the tubes are not so critical, i wish I could find the thread. Regards and best wishes, A.G

Hi Stan, Many thanks for your reply, I have read your build log many times and decided to redo the crank shaft as the there is a bit of run out as you had and the rotation is not concentric. My concern is more to do with the oscillating valve. If I locktite the pin to the central hole it will...

Hi and my best wishes for Xmas and New year to everyone, I have now finished the construction of Elmer's no1 Radial engine. It does work but not very well, I suspect the valve arrangement is not optimised as yet. There is a constant flow of high pressure air from the exhaust vent at the...

Hi, I got the plans from Jan a couple of days ago and ordered some test tubes from eBay, I just hope that they turn out to be the correct size. Regards, A.G

Hi Brian, This happened to me a couple of weeks ago while I was turning the register boss of a back plate for a Toolmex chuck on my Taig lathe, everything was spot on untill the last cut of 0.002" to bring the registrer boss to the correct diameter but it all went wrong, it was over cut by...

Hi Jason 4420, I built this engine last year and I love the way it works, it has a very nice tone to its exhaust. Well done and keep on going. Regards and Greetings, A.G

Hi Gus, It is better if they didn't change color but provided the steel is a good one a bit of discoloration should not do them any harm, hope you didn't mind me replying. I use a belt sander in preference to a grinder and I find that it works cooler and I don't need to quench the tool so...

Hi Thayer, As you are using compressed air rather than steam, the oil can be applied with a simple surgical syringe to the external moving parts with great precision, as for the cylinder it can be applied through the compressed air inlet. If you really want to auto lube the bronze bearings...
