What have you done in your shop lately?

I finally was able to mount the oil adapter in a way that I can bore out the oring holes. Previously, some people advised that using a drill bit wont work well for oring. That was good, and I thought using a lathe to cut it would work well. However, something else I learned later was the oring squeeze is very specifc. Drill bit sizes dont work out; and I can't get the oring to work since the holes only need some thous larger. I already welded the piece and had a hard time mounting the larger piece to bore due to clearance issue. The orings fit great after the bores. The bored surface is so smooth and beatiful. I really love lathes and milling machines (or am I now dependant on them?)

Today, I was making a boring bar extension. Still need welded.

Let us know how it works.
I made an extension couple days ago. I used a 5/8" x 6" grade 8 bolt and welded a 1/4" brazed carbide cutter to the side. Turned one end down to 1/2" to fit boring head. It was a failure. Used it in wood and it chattered really bad. Don't think I'll it try on steel. Live and learn.

Sorry to hear it didn't work for you. I hope to get it done tomorrow. I will update it. The length is not much more than current longest bar, which worked very well on aluminum. This gives me clearance on the side and a larger diameter.

The two pieces were cut from a mower shaft. It was hard, based on how hard it cut from a cobalt parting blade, but I don't know. A wide two studs helps almost 8x the side strength, but only double on the front strength. Twist torque also more than 8x single 1/2". That is all theory. We'll see how it work. If it works well, I will try on some mild steel.

Replaced the felt wipers on my Clausing Colchester 15.
The old ones were cork and were hard as a rock. (that's not a scored way in the second pic, I could wipe it off with my finger, just smooge)

I love these felt. After replaced my lathe with similar felt, and after a while, the apron slides smooth like butter.
I need to add/make 4 for the cross slide (no felt at all currently )
 
Today I welded the boring extension and tried it out. It worked rather well for what I needed. I only cleaned up a little, so not a good test. You can see the picture below. The top looks ugly because the side curves in, and it is not cut by the blade, but rather ground by the back of the blade/tool. Neat the bottom is very smooth. I cut very slow and little at a time. So I don't know how a real cut would be, but for what I needed, it does exactly how I needed it.

The black curve in the middle is the corner. Inside of it is the bottom, not wall. On the left of that middle curve is the wall where I cut. I welded the holder at a little angle, which makes the blade almost vertical, but not quite. Because the wall curve in on top, the back of the blade rubs against the wall causing those lines.
 
My pine tress got the better half of the last 5 days . Trimmed 5 trees up about 6 feet off the ground and burn't it all ! I haven't cut under these trees for about 12 years and there was trees , vines , raspberries etc growing up thru the trees . I used the generator and the sawsall with an 8" blade . Worked great but dragging all those branches over to the firepit took quite an effort . I also got part of the front of the house primered and ready for paint . Did this with a brush and rough roller . Never again , a sprayer is on its way to finish this job . :grin: Nice to get back into work to catch a break ! :rolleyes:
