Re: drill bit helix

The reason I asked is that I have a 3/8 drill with a fast twist the came with a can of drills and I just wanted to know what it might be useful for. Its not unusually long or special in any other way. The mention of drilling long holes reminded me of gun barrels and the time I was offered a 38 calib...

drill bit helix

Why do a few drill bits have a helix with more turns than the standard ones. Are these for some special use.

Re: Rough strength equivalent

You need to remember that a smaller tube will hold as much as a 2x4 in a vertical position but as a beam it may have less strength. There are tables that give the safe working load for lumber and steel both as a post and a beam. Do some internet search's.

welding a shaft

I want to weld a piece onto the the screw from a vise, it's about 3/4 inch diameter. The weld will be two inches from the threaded portion and will be replacing a old botched repair done by a previous owner. I plan on making the new part slightly larger than the final diameter and turning it to size...

Re: Horrors of Buffer Safety

I used to buff aluminum as part of my job. Very dirty and hot work. Your clothes will be black! Wear eye protection, leather gloves, and impact toe leather shoes or boots. Until you learn it and sometime after, you will have pieces of work pulled from your hands and thrown to the ground in front of ...

Re: 100+ Years ago

I read an article in a lumbering magazine about a sawmill in Switzerland. All of the logs go thru a metal detector. Some of them come from France and Germany, but even the Swiss logs may have shell fragments in them as bullets don't recognize borders.

wheel pullers

I have stripped out the threads on two wheel pullers with acne threads and just picked up two others at an auction that have fine V threads. The new to me ones, with fine threads were made by the Owatonna Tool Company here in the US. I would have thought that the acne thread would be stronger but it...

Re: Sourcing pig iron

In regards to "mystery metal", we had a local manufacturing plant with their own foundry. At one time they melted anything as long as it was cheap. The last years before they closed the foundry and outsourced their casting they only used railroad rail. It had to do with quality control.

Re: VFD question

Yes a forklift motor with an electronic control circuit is the way to go. Here in the States, forklifts that don't have swapable batteries are often scrapped when the batteries wear out because the new batteries are more than half of the cost of a whole new forklift. Good Luck'

odd threads

I picked up some Little Giant threading dies at a flea market. There are a couple BSF sizes with them, not marked BSF but the diameter and tpi match. There are also a 13/16-10 and a 1 1/32-8. Another one is marked 7/16 1/32 14 ? I can't find these sizes listed anywhere and the 7/16 one has that odd ...

Re: endmills in collets, and using in horizontal mill

The mill is a Hardinge UM with a Rusnok head on the over arm, it uses Y collets and has about 10 inches from the collet to the table. It has its limitations but I got it cheap enough.

Re: Dubious Restoration

A little off topic, but I've often thought about the old "restored" tractors raffled off at tractor shows. They seem to run good, and the paint is nice but what I wonder about is if repair and paint equals restoration. To me restoration equals returning something to it's as new condition inside and ...
