Very cool stuff on these mods!
I am so gonna have to get in on this modding thing, LOL.
Lathe wise, I have one of these...
Edit... errr well, no linkies yet but it's the model # 44859 on the www (dot) harborfreight (dot) com website, LOL. (8x12 precision bench lathe)
The 8x12 is another category from the mini-lathe some others posted. It's still small-ish but about 3x the weight and rigidity of the "Mini-Lathe". It's $549 retail, but you can get 20% off coupons a lot of the time which cuts it to $460. (if you want a link to a coupon, PM me... I'll probably have one.) It will do "Real work" albeit on a smaller scale.
Ohhh, and hello world! It's my first post on the forum, had my 510's for about 4 days, LOL.
