I've been in the market for a lathe upgrade from my 7x12 for a few months and am thinking about pulling the trigger on one of the new ENCO 12x36 lathes with the curved face on the head. I have not been able to find much on the new model of this lathe. Does any one here know of any experiences...

I thought I remember coming across a electric safety carriage stop for the mini lathe. The idea is to put a micro switch on an adjustable stop which will come in contact with the carriage if the lead screw is not disengaged. Once the switch is tripped the power to the lathe is cutoff. I've had...

I'm considering the use of aluminum for the hot cylinder on a alpha Stirling engine. I plan on using graphite for the piston. Does anyone see a problem with using an aluminum cylinder? I noticed many of you seem to use stainless on your hot caps for gammas. I just happen to have plenty of...

I've been lurking around this forum for a while, leeching all sorts of good information. I think its time I contributed. I've had my knurling tool done for a couple weeks but I haven't got around to getting the pics in order. Here are a few pics from my knurling tool adventure. Sorry about the...

I'm trying to turn down 4 inch 6061 to 3.1 inches on a 7x12 mini lathe. The first problem is getting the tool back far enough to even make the cut. To do this I set the compound at 31 degrees according to the protractor on the machine. Is this the correct way to get the tool back far enough...

I've been looking at the Jerry Rollet's Belt drive plans and I noticed he recommends Fortal 48,000 psi Aluminum. Most of my stock is 6061. Would 6061 be suitable for making the pulleys?

This actually happened some time ago. I was trying to trim up my displacement piston on my Stirling engine. I needed to take a bit off the end as it was coming in contact with my cylinder at high rpm. I'd already removed a hundredth or so off the end. I went to make one more light pass and...

Well I've had my first runner going for a couple of weeks but just today I'm finally happy with its performance. I first used aluminum for both the cylinder and piston on the power side. It ran well for about an hour before wearing out. I replaced the piston with brass which ran well but the...

I've been sniffing around this board for a couple weeks while looking for help on my gamma Stirling engine. My Sitrling fired up for the first time two weeks ago and it was running great, but within an hour of run time I noticed the power piston/cyl was showing pretty significant signs of wear...
