The Home Machinist!

I have a few parts I need made on a lathe. Some are 2 of same part, others 1 only. Material is 1044 Stressproof. I can provide material if necessary. Can provide CAD files or printed drawings. PM me for details.

Thanks Exodus

Needing a bunch of small shapes cut out of 1/16" plywood. Laser or small router bit in a CNC router would also work. Email me for DXF file.

Just a bit curious if the gun's barrel is stainless too? If it is then I could see the reasoning for the same/similar metal. If it isn't then why not use the same as the barrel? Going to take a long time to wear out the "attachment" under normal usage. When you do, you can make another if...

Got some more info.

It is probably NOT INCONEL™ 718. A finished product, roughly 1" X 2 1/8" retails for $59 which pretty much rules out 718.

Some of their other literature suggests 17-4PH.

Thoughts?

Ref: http://www.advanced-armament.com/pdf/manuals/aac_manual_m4-1000.pdf Scroll down where it says Flash Hider Material What is High Temp SS? Ref: http://www.advanced-armament.com/product.aspx?pid=29#pid=119 Their description says it is a "high strength corrosion-resistant aerospace alloy"...

Glenn has a good way if you want to bore it and if the small hole above the bore in the two rings goes all the way through you could use it on a dowel pin in a base plate to align the rings to bore them. I think it is a blind hole. I'll put my boots on a tromp through the snow out to the shop and c...

Some more pictures

Yes. The one in the picture is actually the .750 version.

They sell two models. One with .625 bore and one with .750 bore. So there is enough meat to open the .625 version up to .700 Material is supposed to be cast 4140 I already own this so making a new on from scratch seems like a lot more work than necessary. -- I got ya Bill. No drawing needed. -- Than...

I have a flip up front sight that has a .625 bore. I need to open it up to .700. I have a small boring head I can use, but what is the best way to hold this and align it with my mill spindle? What other ways might I do this?

I made a half dozen insert holders for my 12" lathe. I started with 5/8" square bar stock, 4140 from McMaster. After machining, I hardened them. That was about a year ago, they seem just fine. I didn't use anything special under the inserts, since I didn't expect any interrupted cuts or h...

I want to make a couple of special lathe insert holders. What would be the best steel to use that will hold up long term in the insert seat area? Should this area be hardened or the whole tool? Something similar to this, but different angles: http://www.grizzly.com/images/pics/jpeg500/g/g7036.jpg Th...
