Re: tapered roller bearings

I have never considered taper roller bearings as high precision bearings, not like you would consider a spindle bearing which typically come in matched pairs or triplet sets of angular contact bearings with the preload preset. Heh! While that may be true of the common taper roller bearing, the head...

Re: tapered roller bearings

What is your application? what type of precision are you trying to achieve? The clearance/preload in tapered roller bearings is usually set by adjusting the axial length of the shaft, sometimes with a nut (front auto spindles). I have never considered taper roller bearings as high precision bearings...

Re: Magnetic gears?

The big Issue I see is the amount of torque it can transmit. I can't imagine with the size of the magnets very much HP can be transmitted thru it. There have been magnetically coupled pumps and rod less air cylinders around for years. The limiting fact is the strength of the magnets. It may have a u...

Re: Drilling Through Holes on the Mill

Depends on the part: if its not to critical or some material that isn't very flat to start with like Cold Rolled flat bar, then plywood or whatever sacrificial material I can find. Semi critical or heavy machine cuts will be required: I will use some pieces of alum bar stock Very critical: 123 block...

Re: Museum of Obsolete Drafting Technology

I spent about 12 years on the drawing board before we moved over to CAD. Here is a picture of my trusty K & E lead holder, which I started out with before changing to Pentel pencils later on, with all the Nickel plating worn away from spinning the holder/lead as you moved it to keep line width consi...

Re: ALCO cab nose measures?

Absolutely gorgeous headlight and worthy of a PA1 ! Well done! Thank you ! I am trying my best not to be a rivet counter on this loco so I can get it done in a reasonable (that's a very ambiguous word) amount of time, I am doing that on a Shay that I am building, and just can't help myself. As much...

Re: ALCO cab nose measures?

I got them at O'rileys auto parts came in a pack of 2, Seem bright enough for what I want, I have only hooked them to a battery in my shop. They are a spot light type. Biggest factor was they were the right diameter to fit the housing. https://www.oreillyauto.com/detail/b/nvision-3937/truck---towing...

Re: Permanent mold hot tears

Your mold design isn't the problem, this is done all the time in the die cast industry. Look at the bottom left part in the picture, the big blobs along the edges of the part are there for a couple of reasons one being for the part to draw material from when it cools so it doesn't have as much issue...
