I have a 2" x 24" boring bar, which I used to do the cannons. Still a reach on a 12x36, & requires a jig. I had a friend with a 2.5" dia. gun drill to ease the labor. Mert

LOL, SKY HOOKS,, LOL, plus the chuck jaws would slam the bed 3 or 4 times a rotate ;)

Agree 100% with Mert. I could do it with a 7x - but would not. It would involve building an external toolrest, and using a linear slide to control the toolbit. The linear slide, new, costs more than a

Rome was no built in a day. I was not the foreman on that job though, and I have advice. Keep your 7x12 for a while, buy a few books, (I'm making a list, but there are some out there already) Play

Interesting. Making beer can mortars is where my experience in this from. I'm set up to bore 'em. Mert

7X12 is the "Envelope". Actually understated; you could, I you had eaten your Wheaties regularly, put a 7" dia. piece of steel shaft 14" long between centers on a 7x"12", if you took the carriage off.

Their tech is recommending replacement to the shipping department. There seems to be a light pulsating when in reverse, shaking the machine a little and when the switch is 100% for sure on off, I

Surely need a larger lathe for that. Sounds like you are very new to lathes like myself. Find some smaller projects to do, so you can learn more about lathes and machining. Ask questions along the way

Yup! Several coats & pay particular attention to the edges. Roy

I have a free counter top off of Craigslist. Works well so far.

I used a commercial cookie sheet, aluminum with steel rim reinforcing. You can see it in the photo of the hand-wheel mod I did http://interstellar.com/temp/Lathe/Hand_Wheel/Hand_Wheel_3.JPG Under the

For extra protection around it, you could lay down a layer of aluminum or stainless sheet under the lathe.? It will keep the cutting fluids from attack the varnish and eating into the wood. -rw

i'm using 2 sheets of 3/4 mdf. so varnish, etc should be enough ? thanks, george ________________________________ To: 7x12minilathe@... Sent: Thu, October 13, 2011 5:00:24 PM Subject: Re:

Thanks for all the suggestions. I guess I don't have much choice but to farm this work out. Due to the nature of the project (Coehorn mortar barrel) it's not possible (from a safety standpoint) to

George, 3/4" MDF would work just fine. Seal it with several coats of varnish first.

A practical example of this is the solid fuel boosters used on the Space Shuttle. The original design had them made as one piece, but the lowest bidder was on the other side of the country and the

All good answers: You are now being introduced to the "specsmanship" of lathe specifications. Actually, if you removed the saddle, you probably could get a 7 inch by 12 inch cylinder between centers

my bil is gonna put my lathe table together for me. we are wanting to know what is best to protect the table, mdf, before we put the lathe on. thanks, ? george

For a hobby lathe, that's major engineering, and I'd farm it out. It won't fit over the cross-slide (or even over the carriage). And to bore it, you would need a boring bar 12" long, so to start at
