Thanks for checking out my blog, I'...Valentin,<br /><br />Thanks for checking out my blog, I'm glad you found the information useful.<br />In answer to your questions:<br />1) I used a DC motor because I had it :-) and also it was easier for me to control the speed.<br />2) I'm not sure of the HP but I believe it's 1/2 HP or maybe 1/4.<br />3) AC motors can be controlled for speed and direction. There are solid state controllers for doing that or you can use a pulley and belt setup.<br />Be careful! Rotating stuff and high voltages can be dangerous.<br />Good luck with your project and let me know if you have any more questions!<br /> - OttoOtto Beldenhttps://www.blogger.com/profile/01216660670383308620noreply@blogger.comtag:blogger.com,1999:blog-8604042776942832369.post-12670034469330849802010-12-27T19:48:47.202-08:002010-12-27T19:48:47.202-08:00Dear Mr. Belden: I need to have a woodworking lath...Dear Mr. Belden: I need to have a woodworking lathe and being short of funds obviously decided to DIY one. Went to internet to get some inspiration and found your blogpost. The mechanical parts of your lathe seem fairly easy to built, but the electrical parts are not¡. (That shows you that electrically I am almost analphabet). If you are kind enough to spare a few minutes of your time and answer a couple of questions, I`ll appreciate it.<br />1)Why a DC motor? (Obviously you had one around and is free¡¡¡ right) I suppose the other answer is the speed can be controlled. Right?<br />2)What is the HP of the motor?<br />3)Can an AC motor be speed controlled and/or reverse?<br />Thank you for your attention.<br />Sincerely,<br />Valentin Bezugly<br />lasercontrol@gmail.com<br />City: Acarigua<br />State:Portuguesa<br />Country:Venezuela.Anonymousnoreply@blogger.com
