    Default Mini-lathe bed extension kit

    The next purchase I have planned for my little 7x10 is a 14" bed extension kit for $150 from littlemachineshop.com. I know that puts my total cost up at the 9x20 cost, but then again I don't need 9" bed travel with my projects. 7" bed travel will be plenty for anything related to gun stuff I can imagine. Seems like it is a pretty basic upgrade... drill and tap a few holes and move all the parts over.

    The bed extension kit supposedly makes the travel a "true" 14" travel and not an "abbreviated" 10" or something stupid like the 7x10, whose true travel is actually 7x8... anyone have experience with the extension kit? Good/Bad?

    I'm really not interested in spending $1500 on a lathe at this time. Maybe next year...

    HF runs an in store special on the 9x20 of $499 a couple of time a yr. The 7x__ are great machines though I built a 10 bbl gatling gun on my 7x12 and one of the mini mills last year.

    Here is a link to a yahoo group were the guys are bolting 2 beds together to make a 7x24, check out the photo section for some pics of my cnc ballscrew conversion of the lathe and a cnc tailstock

    I used my 9" bed Sherline lathe to turn down a FAL barrel to fit into a yugo trunnion.

    I think I have reached the upper limit of what I can accomplish with this tool.

    I am saving up now so I can buy something that has a 1.25" minimum spindle bore.

    I think you're right. I didn't think about reselling the one I have! I don't want to spend all my shop time making more tools... I'd rather spend my shop time making "stuff" - ya know? I'm just afraid of spending more money when most of the use will be for hobby stuff.

    Here's the question now - what size lathe do I need to go to that will handle a 1.25" through-spindle piece?

    probably a 13", the 9x20 is just shy of 1", my 14x40 will pass almost 1.5" thru the head. I would get at least a 9" swing , I have on occasion built tanker garands, turned hk bbls etc while still installed in the rec and the extra clearance is nice

    HF's 12x36 is 1.5 through the spindle

    I picked up my 12x36 from HF a few years ago when they were having a sale and managers special, IIRC I paid under $1500 out the door. I started looking at the 7x10 then the 9x20 but after about a 4 years of thinking about it, I eventually decided that bigger was better. I have yet to regret buying the bigger lathe.. Turning my car's rotors would have been hard on anything smaller.

    The 12x36 was on sale for $1799 recently, and I had a 20% off of any one item coupon that I could have used as well, so I could have gotten it for $1450 or so. The wife woudn't let me get it, it would mean she would have to park outside, I need to use her bay to put it in and that didn't make her too happy. Go for the bigger lathe, you won't regret it. I have a 9x20 and so far I've been real happy with it, but I wouldn't mind a bigger unit.
