Grinding Bushings

Grinding hardened steel bushings, a side job from work. Grinder is a manual feed DoAll DH612 with a Selectron chuck

Some prototype shooting coat buttons. OG (right) and updated proto (left). 4-40 UNF thread, 1" OD head. 1018 mild steel.

Maybe more to come on this project, thanks for looking.

Tool Bit Grinding Fixture

Built a tool bit grinding fixture for the surface grinder. Can hold 3/8", 1/4", and 3/16" toolbits, aswell as 1/4" round using the shoulder from the 3/16" cutout. Still need to make a clamp, but nuts and washers work for now.

Has a 7 degree relief angle built into it, but if I need more I can use the wheel radius to help me, and feed using the (In mill terms) Y axis.

Hard Turning HSS

Hard Turning (Non Annealed) HSS center drill, using cheap Chinese brazed carbide on my South Bend small spindle 13. Old iron still chooches!

Few thou feed (not counting....) with a .0013 feed/rev. ~900 RPM. Bronze chips!

Thanks for looking, as always keep the hot chips flyin'!

Feinwerkbau 700 Trigger Shoe

Made a new trigger shoe for my Feinwerkbau 700. It's made from 6061, has a serrated flat face, and fits on the OEM trigger post. Threaded M5-,8 and fits right on. Much nicer feel than the original plastic curved one!

Introduction

 Hello,

This blog is a ongoing documentation of my gunsmithing and machining projects, along with machinery moves, fixes, upgrades, etc. Basically a place to write about what I'm doing in hopes to entertain or inspire others.

 I've been dabbling in machine work for about a year in a half now, a close family friend noticed my interest and gave me a 1948 Bridgeport "M" head, and used that for a year. I soon realized my need for a lathe. I bought a Craftsman 109 from Craigslist and that was a great starter lathe and machinery rebuilding experience. I then thought a surface grinder would be handy, so I went looking. A DoAll DH612 hand feed surface grinder came up in the classifieds for $400. He mentioned his friend had a South Bend. Me and my dad went to look at the lathe. It was a 13" South Bend with a 6' bed. Had a QCGB, collet closer/nose and collets, 3 jaw Cushman chuck, 4 jaw Skinner (South Bend) chuck, taper attachment, collet rack, micrometer stop, Aloris AXA toolpost and 5 holders, the original "lantern" toolpost, steady rest, faceplate, and some assorted tooling like centers and a drill chuck all for $850. 

 Both machines were purchased and moved into the shop. The lathe came wired for 115v 1ph, so it's already wired for house current. The grinder takes 3ph, so it will be getting a VFD soon.

 Hopefully you will follow me in my endeavors, and might learn a thing or two (hopefully!)
