I made a metric M1 rack today of 48 teeth.
I had been making some change gears for my old China lathe last week and that got me to thinking about making a rack. I had made a 90 degree gear box for my mill last year but things happened and I never really made anything with it.

I even shined it up some.
Thanks for looking

I spent a day in my shop on company time. I worked on a project for a job that requires hundreds of feet of coated rigid 1" conduit to be installed exposed on the wall of a water treatment tank. This conduit can be ordered with the radius required but the lead time far exceeds the completion date. We bought a pipe roller from HF and tried it out on a stick of pipe that was not coated. It worked great.
When the coated rigid arrived we discovered the pipe roller would not work.
I have a good supply of structural steel that I have accumulated over the years.
I grabbed a piece of 4x6x3/16 tube steel did some cutting and drilling, added in a little flat bar and welded it all together.
I got lucky and the modifications were a success. Now I just need to paint.

I thought my little flywheel really needed spokes but without a mill I couldnt think of a cool way so I just drilled some holes'
First off I used my simple indexer to place 8 marks.

I used the sharp tool bit to scribe a cross line

Then remove from the lathe and centre popped then set up on the drill press with my nice strong clamps and drill the holes.
Completely forgot to take a photo of this.
so only the final shot.

Today i've been cleaning the big garage, i did manage to clean out the side bay of the garage. Moving the diesel engine wasn't that hard but moving the entire drivetrain was much harder than i thought then i finish welding the seat mounts in the little niva and then i moved it in the bay and swept the entire garage floor.

A simple project that took way longer than I expected. Fasteners for an ice cream machine. The plastic ones had cracked and had stainless thread inserts, stainless on stainless for something that gets used often is a recipe for disaster.
Roughed the body from 2 inch aluminum, then drilled and bored for the insert. Made brass inserts 2 thou over size. Warmed the body for a shrink fit and dropped the inserts in. Milled the finger grips then powder coated. Worked on them when I had time, ended up taking about 6 hours ! He gives me pots of work, will have to cut the time in half.

Today i started on the rear bumper mounts and the rear hitch receiver, the old mounts had lots of rust so i decided to make new ones from some very thick wall tubing. The rear mounts are reinforced when i rebuild the back, couple of months back so i'm confident this will be sturdy. For mounting the bumper i had to weld up couple of broken bolts also made couple of plates and with the bumper place where i wanted it i weld it in place, i also cut a thick piece of square tubing for the hitch receiver and made me a receiver from some thick angle iron. Working with thick steel is much easier than rusted sheet metal. Thanks for looking
