Haha, Bruce built the Parts for his CNC Mill on my CNC Mill
I've just started a new job, was too knackered to go on Wednesday Evening. It's good that you got there and met a few of the Guys.
I'm rostered on Track Duty on the 14th. Come on out, introduce yourself and have a play on a Loco.

So, having pretty much decided that the AL-320G will be the lathe of choice. Even though i keep looking at the AL-960B from Taiwan cose the finish on it looks really good and its only about 450kg.

One thing i notice on these Hafco machines in this $3k plus price point is the cross slide has no t-slots. Probably cose they expect you to have a mill.

Buying into this sized lathe means i need to save a bit longer for a mill, or more accurately a mill/drill.

Thus the question to the collective is does anyone have any experience with milling on these sized/style lathes that have no t-slots? If so how did you solve the work holding problem with no t-slots?

Or am I being a plonker with this question and if you have this sized lathe you shouldn't be mucking about trying to do simple milling opeartions on it and should break the rust on ye olde wallet hinges and get a sodding mill.

Sorry, been looking for any excuse to use previous emogi. Its just too cool.

Cheers,
James.

Actually James, you are quite correct in querying whether it has a t-slotted slide.

For between centre boring, it really is a must, and because mine doesn't have one, it has stopped me machining a large cylinder casting for a while now. I can do it on my mill, but it means using a boring bar held at one end and it is almost 12" long, using my right angled head. Not a solution that guarantees success.

But all is not lost.
Myself, I am fitting a cast iron removable slotted table to the top of my cross slide for when it is really needed. They are readily available at very reasonable costs, just need modding to fit your particular machine, or maybe there is enough meat on your cross slide to machine in some small t-slots. But you must be careful that you can still reach centre on the job with the extra thickness of the sub table.

John - I had been wondering if the removable table was the solution. I'm not too keen on the thought of hacking t-slots into the original cross slide. But adding a table will reduce the max swing over the slide. I guess that is better than no option to mount on the cross slide at all.

Cheers,
J.

My sub table on a long forgotten 920( actually an Axminster 9180) was peppered with tapped holes to hold the old bits from a Zyto, a Myford ML7, a Super7 and I presume will increase from addition of the 'new' Myford ML10.

Thinks? If I flogged some of them But then H.M. Revenue and Customs would want their share after I head for the local rubbish burning department for the statutory 9 minutes.

Cheers

Another approach to the t-slot problem could be per this page:
http://www.wrathall.com/Interests/ma...oss_slide1.htm

Of course such a solution will need some kind soul with a mill to assist since it needs a mill to cut angles, steps, drill holes and counter sink various fasteners.

Cheers,
James.

I'm sure we could find a "kind soul" - may need to buy some new tooling though - ohhhhh new tooling

Norman - not sure how things work in Old Blighty but sale of something that is "second hand goods" if not done in a manner to suggest it is part of your normal income generation isn't typically taxable.

Bruce - yeah NEW TOOLS! And I'm sure beer or similar beverage of the kind souls preference can be procured to support the cause.

But got to sort this blasted garage out so I have ROOM for the soon to be procured lathe.
