Perhaps a wooden frame fixed to a wall on an angle etc,etc etc
I'm looking into it both re general tool management within the drawers I have and in the particular case of the collets re the interlock concept. I don't need the interlock ability at the moment but I'm mucking about with some male/female designs to prototype the dimensions. Got to love plastic with its shrinkage, makes exact dimensions on holes and cutouts not very exact.

Default BF20 Mill Stand continued

Some more progress on the mill stand. I managed to work out a way to get a home for the bandsaw elsewhere in the garage which allowed me to simplify the design and just weld it all up.

So here are a couple of pics.

Overview of welded frame to date. Bottom frame is done but yet to do all the bracing yet.

Close up of one of the wheel mounting plates and the associated bracing to help spread the weight. Plus I had this 80x80 angle iron that was just crying out to get some use.

After much faffing about I have a drip tray that is starting to look half reasonable. Still some more welding on the back side of it and then a good amount of cleanup needed but things are starting to look promising I think.

Default Mill table finished and mill installed

Its finally done with great help from Bruce today dealing with the install and the fact I managed to screw up some measurements. In my defence I did follow my plans to the letter and about 4 versions back it was all correct, however at some point I rejigged the central support dimensions and didn't also compensate the hole locations. The lesson being, doing changes late at night is "Bad"

Fortunately Bruce talked me through the options

Net effect is mill is installed an now I need to get it all cleaned up and start using it. First order of business thought will be to make a new drawbar with an M12 thread instead of this odd 1/2" Whitworth that is on the stock bar.

James, Have a read of my drawbar adventure in my shed thread starting about here
http://www.homemodelenginemachinist....t=19885&page=5
This was the first thread I had cut and the guys on this forum talked me through it step by step. If you happen to have a collet block set, you can mill the square head perfectly. I've got a feeling I milled it before I had them though..

Thanks Rob. Yes I have read your adventure in threading a number of times. I've had a crack and managed to get a reasonable M12 thread done.

I've seen an interesting video by a chap who shows how to do threading in reverse so there is no panic about stopping things in time. I'm thinking of having a crack at that approach at some point.

Did you ever work out if the thread chasing dial on the AL320 can be used for metric or is it only usable for imperial?

Cheers,
James.

Looks like a nice stand, but are you going to enclose it or make chip shields on both sides and the rear?

Mills make a hell of a mess and throw chips far and wide, they'll launch right over the sides of your bench top. Flycutters being the worst offenders.

Thread chasing dials are just for imperial threads. Remember to change direction using the power switch, not the gear box lever. I had that wrong to start with. Also remember to engage the half nut lever or the pitch will be about double what you set. I forgot that once too!

I think if you measure a 12mm bolt, it will measure 11.8mm so being .2mm undersize is a good thing I think.

BUt what would I know? I've only cut 2 threads

Game plan is a plywood "box" with shelves and doors. Probably a couple of wide low profile draws at the top for holding cutters and chucks/collets.

But I need to leave a space for a box for CNC control electronics.
