Default Ah crap.Broken Cutoff lathe insert holder.

Well while working on the Mailbox hinge mechanism I happen to do the wrong thing and I broke my New (past fall) gift from Pixman..

I was so bummed.. I have had just about enough of working with Hydraulic cylinder rods..

What I should say is they are a unique material of what I can see are cast iron and then made into malleable iron surface hardened rods..

Surface hardened from 1/8" to 1/4".. Pixman was kind enough to show me which inserts to use with the hardened material but I still am learning..


On one of the pins I was cutting off I was getting a little to much vibration so figured I'd lower the rpms to the lowest setting without back gearing and within a second my beloved cutoff tool was completely ruined..

Took the insert and the nose completely off..


((((I made the cardinal mistake. With inserts I should have increased the speed and feed.. (Pixman reminded me of this)))


Anyhow, I fixed it today..

I tig welded it back together.. Yes, I'm not proud of the weld beads.. I was actually quite disappointed with the beads appearance but they certainly should hold.

I welded on some 2" bandsaw blade stock as the reinforcement...

I welded the broken tongue first then put the reinforcement piece on.

Here you can see the fix and this should actually help to make it a little more ridged.. At least I keep telling myself that..


I got a chance to use it today and it worked just the same as before..

And,, Guess what.. I finished a project in record time...

Jen, that hydraulic ram or cylinder pin type of material is very nice free machining if you take the ram and lay it in a wood fire and cook it til the fire dies. Next morning it is great stuff to machine.

A trash wood fire is much cheaper than replacing one of those tools.

edit: I forgot to mention how much of a neat repair you did.

Its the mark of a good tradie, that when a blue is made, you are able to repair it and move on.

tradie = trades person

blue = mistake or error

Good fix Jenn.

That is a great idea about putting in the fire.. A good annealing will do wonders..

I actually only have a few of the rods.. I'm a little mad at myself since the guy who did the cylinder rebuilding is retiring this year and I only found out about the scrap rods a few years ago..

Everytime I go out that way I always check the scrap bin since they just give them away.. I've only gotten lucky twice..

Had it been 5 years ago I had 17 brush fires but now not much junk wood around..



Thanks all.

Jenn, nice repair.
As for junk wood find a place that gives away pallets, a friend of mine has been burning pallets for years in his outside wood burner to heat his home and shop. He used to cut them up with a Skilsaw and then burn them in an airtight stove in the house, until he got the outside one. He can put a full length runner in the stove. He built a pallet breaker that runs off the hydraulics off his tractor. He gets broken and damaged unbranded pallets from about a dozen places around the area.
The moral here is some places give them away instead of adding them into the dumpster.
Dan.

Jen how about an "I" for ingenuity. Remember..it's not how bad you F up but how quick you recover..
