Sometimes the easiest method is to weld your part to a bar and put the bar in the vise. I have about 8 toolmaker vises in several sizes and these are quite handy for holding small parts. Maybe drill a hole in the part and use a screw to hold it to a bar for sawing. The hole would have to be where it...

How about a reinforced resin bonded cutoff wheel, 1/32 - .050 being spun in a lathe chuck? Clamp the blade in an Aloris type adapter, use the carriage for notch spacing and the crossfeed for depth of cut?
Just a different idea....

I keep a swivel base under my Kurt on the B'port all of the time, just handy for the kind of jobs that I most often do on the mill. There are aluminum sheetmetal formed covers that cover the rest of the table, fitted very well up against the sides of the swivel base. They are reversed when I have on...

I've had very good luck with (quality) hole saws in the 2"-3 1/4" range through 1/2" steel plate. I use my BP mill but am probably below 100 rpm. I use lots of cutting oil and clear chips often. It does take a lot of pressure to keep it cutting. Only try this with bi-metal hole saws. ...

It only takes a few minutes to make up a bunch of blank wedges from CRS and cut the slots to fit the taper when you need a set. I did this years ago and have used them quite a few times.

I'm cheap and hate to wait for stuff that I order.

Going through material that thick with a 1/4" diameter piece of HS is going to be quite challenging, probably impossible. 100 rpm may be too fast, depending on the diameter of the hole. I'd try high speed tool steel and see how it goes. Drilling followed by boring will probably a lot easier and...

Use 4140 and do what Bill Cook suggested. That is how Remington does their rifle bolts that are made from several pieces.

Kitchen ovens often have temp swings as the heat is turned on and off. I'd put a piece of metal, or several, in the oven to act as a heat sink, reducing the temperature swings when it was cycling.

The most important think about owning/building suppressors in the US is to have the proper Federal paperwork. Each of the 50 states have their own rules which one will be aware of when you begin your Federal (BATFE) license application. My state, Idaho, allows full autos and suppressors while next d...

Nice stampings. How about showing us the tooling?

Thanks,

I had one that leaked oil so I took the bottom off and made a gasket or used latex or whatever to end the leak. What I saw was that when the lever was in the "OFF" position, it merely moved steel bar(s) into place that cancelled the magnetic function of the magnets. So simple that I was re...

Your original idea of drilling holes is probably not a bad idea. I have "chain-drilled" a plate to make a rough disc when we did not have a saw that was suitable. You drill a series of holes outside of the finish part diameter, holes almost touch each other but not quite. You can then easi...
