Re: Fitting and bonding corrugated metal roofing sheets

Look for a local sheet metal shop. They should be able to provide flat stock and any basic working, like if you needed some 2" wide material they could shear a 4ft wide sheet in half.

Re: Heat treat temperature calibration

Look into thermocouples. They are very accurate and relatively inexpensive. You can probably find a unit ready to go on ebay.

Re: Fitting and bonding corrugated metal roofing sheets

Could you use flat, un corrugated, sheet metal? That would make fitting end pieces ever so much easier.

Or, what about making the end caps out of fiberglass? That would could be laid up in place to match the corrugations.

Re: Fitting and bonding corrugated metal roofing sheets

Several options.

Some rivets to hold things in position are usually a good start or you can use sheet metal screws or clamps and move them along. Galvanized can be soldered, with caution, watch the fumes. Or, you could use a mastic roofing tape and then rivets for a fairly durable result.

Re: Whatzit?

Yes, a rotabroach or cousin. Look on ebay for shiny ones. Work wonders for drilling large holes without turning everything into chips. You need a mag drill or mill to run one - not hand held!

Autocon Delta 40 setup

Having a problem with an Autocon, Delta 40 system. An early error, intermittent, is "No Signal". The bootup is a bit slow, and there are two endings. One indicates a reset is necessary, and the panel reset has no effect. The second is a halt midway through with the instruction to press "F1" or "Del"...

Re: Lathe Compound

Nothing says that the QCTP has to be squared with anything. Yes, most convenient for most operations to have it squared to the ways, but it only takes seconds to change it to a more convenient setting for a particular task.

Re: Moving machinery without a liftgate

For one of my moves a number of years ago, I got a bunch of pallets and stacked all of the boxes on pallets then shrink wrapped each stack. Other items and tools were creatively strapped to pallets. I rented a forklift to load the pallets; it made quick work of the job, and it saved a lot of back st...

Re: Trepanning Revisited

Here is a specialized tool holder for getting in tight places and maintaining a stiff mount. The concept came from Model Engineer's Workshop. The tool holder is called a Piddington ?; Brits name all of their tools after the originator. There is a second set of set screws underneath so it can be as a...

Re: Trepanning Revisited

How are you holding the bit? Is it mounted directly in a tool holder with minimum stick out?
