Re: Installing thread inserts

J-B weld would have us believe you could fill the hole with their metal-filled epoxy, then drill and tap it. You could, but it won't hold much before failure. Unless it was a plastic part that the j-b weld strength exceeded the strength of the material, I wouldn't do it. In fact even on a plastic p...

Re: Drilling holes in rocks - Help

I'm a Hilti fan.I haven't used this particular model but it is similar to what I have.

Re: Installing thread inserts

In answer to your question the tang can be broken off with just the tap of a punch and then your fastener can go all the way through. As long as you have the correct tap a helicoil is a good and fairly easy repair. It sounds like others have given you sound advice as well. You will have to let us kn...

Re: Installing thread inserts

Thread serts generally come with a specific tap for the thread sert in question or they will specify what the thread for the insert should be if you don't buy them in a kit. If you aren't sure of yourself start with a helicoil insert first, then you will still have multiple chances to install a thre...

Re: Pull start repair.

This is just a thought, if you cold mark on the outside cover where the shaft is, you could cut a hole in the outside cover big enough for the shaft to pass through.Then you could make a patch to cover up the hole and screw it to the cover. :roll: Like I said, just a thought. :D Jackl The lathe was...

Re: Pull start repair.

I've made repairs like this. I clamped the housing down on the mill and used a boring head with a left hand tool to turn the shaft down. I next made and pressed/loctited a sleeve on the shaft. I think Harold's idea of making an oillite bushing to bush the clutch assembly is a good one. What is this ...

Re: How Would I Bevel a 6" Piece of 1/8" x 1" Bar Stock Across Its Length?

Attach a piece a little longer than you need to a piece of scrap. My favorite way to do something like this is to tack weld it to the waste piece, do the machining operations and then cut it loose.

My name is Brian and I'm a toolaholic.

Re: Need to broach a square hole...

Drill a hole to the diameter across your flats and then use the lathe carriage to shape the corners. If you put the work in a four jaw you can use the jaws to index the part. It actually goes pretty quick, if you only have a few parts to make. I generally just grind a tool from high speed steel for ...

Re: Flap Wheel Grit for Good Finish?

I like to go straight to 120 from roughing. With an angle grinder it doesn't take long to clean up the scratches from the course grit. I also make sure the abrasives are tailored to the material. I have separate abrasives for steel, stainless steel, aluminum, etc so I don't cross contaminate but you...

Re: grinding wheel storage

I hope you saved the pieces of the wheels that failed the ring test. I use dead wheels in the same manner you use a dressing stick. They work and you can get a little more use from an otherwise dead wheel. Depending on the wheel, that can be a good use, but consider that aluminum oxide is MUCH soft...

Re: Miller 300 amp mig runner?

Thanks Dave,

I am going to get this one and see how it runs. The only thing that I am not sure about is the Bernard gun that came with it. Everything else I have used has been Tweco stuff, but this is the one that comes with the machine so time will tell.
