I am a "once-in-a-blue moon" member, contributing little, but learning a lot. Can anyone tell me what these are for? The sharp tip is removeable, and the prongs are springy. Thanks Pierre

I know that cutting, grinding and polishing wheels embedded with diamond particles in the base metal are normally used with some cooling fluid (i.e. water). I'm not sure about the abundance of other diamond abrasives available today where the diamond grid is just 'glued' onto a metal form...

I am in the process of converting a small 1” vertical belt sander into an inner profile sander. I will need two 1” wide X 1” dia rollers (using spring pressure) to keep the belt formed on a new profiled vertical backing plate. Before I start the tedious method of experimenting with various...

I joined a while ago, but had not yet asked or contributed anything yet. I'm a pensioner living on Vancouver Island, Canada, and have only recently started with model engineering. I have a Taig mini-lathe as well as various other useful tools and equipment. Question: I picked up a small tin...

Go to the fridge and take out an egg. Study it for as long as you like, but no measurements or drawings. Put the egg back! (honesty here is important). Go to your workshop, choose any material you like (wood, plastic. alumininum, or whatever), go to your lathe or milling machine, and try to...

If you have some of these lying around with no further use, try it out. It is beautiful cast iron and completely without inclusions or pockets: Piecat

How do I drill two perfectly aligned diagonal holes (say 1/8”), one each close to the ends of a 1/2’’ dia. X 12” long Mild steel rod. I have a lathe and a drill press but not a milling machine. Thanks - Piecat

I picked up this Canadian Tire Mastercraft wood lathe for CD$50 (brand new at an estate sale!). I am not a woodworker, and bought it mainly for the nice variable speed motor and and control box. I am in the process of installing it on my Taig Metal Lathe. Specs: 120 volt, 2.3 amp., 60Hz...

I picked up these items from my local “Restore” branch in Nanaimo, Canada, for CD$ 15. Being ignorant of what exactly they are, I turn to the forum members. Some of them look like reamers with a stepped point, whereas the others are obviously drills. They all are in very good shape, whrere...

Being new to the hobby, and new to this forum, may I start off with a question? I have a brand new fully equipped Taig Metal Lathe with just about all the basic tools except reamers. As there are so many diiferent plans available for small engines with reciprocating pistons (air, steam, gas...

Since I am a new member, with very limited knowledge of the theory of steam or compressed air, please allow me to start with a question. It might be a trivial question, but I am intrigued by it. Simply this: If I build a very elementary oscillating engine with two opposing cylinders facing...
