Dan.
I have adapters made from 1/2-13 threaded rod for this. They are simply pieces of rod about 1/2" long with a smaller thread cut in the center.

All of the holes in my fabricating tables are 1/2 -13 thread. When I need a smaller clamping arrangement I thread one or more of these adapters in the holes.

It has been crappy weather here for the last month. Lots of wind and from minus temps to freezing. Waiting it out till it gets above freezing before I can do much in the shop. Going out to the wood shop today as it is insulated and heated. Gonna work on the 12 gauge inletting of the new stocks. Inletting is a slow process.

I will post some pics after I get the holes chamferred.

yep I know how it is, it is cold and nasty rain here. and makes it hard to do anything, as most the work I do. is in and out of shop all day. and this month has been mostly stuff out side due to the tractor and bobcat already tore down in the shop, so no room to do what needs to be done out of the nasty weather. so I'm going to be hibernating or should say going into brumation in side the house, an just poke my head out once in a while...

It did warm up more than I expected today, so got fire going in the shop and finished the countersinks for the 1/2" holes. The 1/2" holes will be used to mount the plate to the table. The set up blocks I made a couple weeks ago will be used as spacers to bring the mounting plate off the table.

I had an old countersink cutter I have had for years and tried to use with no luck. Someone had tried to sharpen it and the cutting edges were not gound equally so chattered way to much.

So looked through my old large bits for a 1" bit with the right angle (82 degrees). Thought I had found one that would work. WRONG. It was way too flat of an angle so one hole is larger diameter than the rest. Got a different bit that matched the angle I needed to finish the other 3 holes. The larger one will still work fine. Just looks different.

Anyway, got the holes laid out for the 3/8" tapped holes, then got to late to drill them. There is always tomorrow.

Chris...... Two questions..

1# What are the dimensions of the milling plate you are making

2# How did you get your mill drill table so clean looks good what prosses did you use to clean it up

I do not remember the dimensions of the plate. I will get them for you tomorrow. All I remember is measuring the table and cutting the plate according to the table.

It was covered in old hardened oil when I got it, including the T slots. I used WD40, putty knife, scotchbrite, stainless tooth brushes and several rags soaked in WD40. Went through a dozen of the blue shop paper towels too. Took about an hour just to get the table cleaned. Also went though 3 pairs of latex gloves.

I did use a mill file laid flat to get any burs off too.

The rags burned real well in the wood stove.

Chris, I have a flat stone about 3 x 7 inches I use to stone the mill table. At one time it was bigger, as the one end is broken off. Works well for getting the high spots cut down but will not cut a belly in the table like a file can. Got it on a box of junk at an auction years ago.
Dan.

The mounting plate is 12" x 8". Laid out, and now drilling and tapping.

Got the pilot and tap size holes drilled. Used the drill press, as it is much faster that the mill. Got 4 of 40 holes tapped to 3/8-16 by hand. 3 dozen left. Had a Tap Matic I got at an auction about 7 years ago, but gave it to Ron. I was sure I would never use it. Back then I had no intention of getting a mill.

Couple hours hand tapping and I will be all done. Next have to buy a 3/8-16 set of hold downs and T nuts. Could make them but not sure I want to spend the time.

Pics when done tapping.

My mill does not have a reverse switch. My neighbor Walter looked it over and it is capable of reverse. Took of the motor cover and there is instructions for reversing, so add a box, switch and some jumper wires and then I can tap using the mill. Did a quick test swapping wires 5 &6 and it runs in reverse. Get to this on Friday after we get back from her surgery in CO.
