I want to tap a 5 X 0.8 mm hole in a 12.5 mm Stainless Steel bar.

My Black book tells me the tapping drill size is 4.20 mm, done this and when I tried to tap the hole the tap started then stopped and I am afraid to turn it any more as it may break the tap.

What size hole is recommended?

I got the Sieg SX3 striped down and cleaned ready to re assemble.

What sort of grease do I use on the lead screw?

What oil and grease should I lubricate the rest of it with.

Must be some thing I can get in Aust

Paul my stand is based on the plan you provided, some changes to suit the material what I had in the shed.

The flat bar is 12 mm thick, angle is 8 mm thick.

I guess I got a bit nervous with a $2000 plus, top heavy machine sitting on a stand I made.

Hind sight, the tank stand I welded up is still going strong with a 4500 litre tank on it, it has been through a few earth tremors.

I put a couple of car stands under the back of the trailer, wound the jockey wheel up so it is firm, blocked the wheels.
Now have got the mill sitting on the back of the trailer.
Decided to get a boilermaker to weld up the stand, because my welder is too light for the thickness of the material I am using.

Thanks for the photos Paul, that is basically what I am planning to do.

Do your casters lock?

How did you lift you mill on to the stand? Unfortunately don't have any room in my shed for a engine hoist.

Thanks for your replies and ideas.

I decided to weld up an angle iron base, I have enough 65 mm angle iron that is 6 mm thick, and buy some industrial casters these have 140 kg rating per castor..

Is it possible to put a Sieg SX3 mill and stand on a mobile base like one of these in the following links?

Or is there a better idea?

Trying to find room in the incredible shrinking shed.
