Re: Tempering

Should be fine unless the data sheet for the material states a maximum tempering time.

Re: fractional hp motor wire repair

This is good and very important because you can't find, well you can find old ones. Older ones are drying up. Modern motors are available in a wide range of configurations provided your budget isn't "Tuppence & a Balloon" and a competent machinist ought to be able to modify a motor for their own re...

Re: Let us discuss

It's neat but at the end of the day it would only interest me significantly if it ended up in an RC car or if it was made at a scale which would enable me to sit in and drive the car it's fitted to.
Engineering at less than 12" to the foot is simply Engineering with some ambition subtracted! :D

Re: fractional hp motor wire repair

Research temperatures and specifications?
I just buy good quality new motors, nearly everything I have is 3 phase with a VFD.
I do make good money with my shop time though, so it matters to me how much of it I spend on inconsequentials.

Re: Choosing an end mill for the job

For the same SFM, number of flutes and chip load an end mill 1/2 the diameter can turn twice as fast cutting twice as many chip per minute. It would seem it would be able co complete one pass in 1/2 the time. Given that you should be running the correct rpm for optimum use of the cutter with the wo...

Re: rubberflex collets for model 50 chuck

I have a tapping chuck which uses rubberflex collets, I was able to find a couple to cover the range of the tapping chuck but I did find some which wouldn't even fit in it so there are definitely at least two sizes of chuck.

Several nominal metric size fasteners have 3, 4, or more pitches in fairly common use.
So you've never encountered 1/2" UNC, 1/2" UNF and 1/2" UNEF and variants in the same size? :D
You should get out more ;-)

Re: metric drill set explained?

The problems are not with measurement systems, the shortcomings lie with the users who can't cope with basic maths or make stupid assumptions. The ship example above just shows that not everyone understands Cumulative Error :D I have to work with a mix of metric and imperial fasteners and I find bot...

Re: metric drill set explained?

That said, I'm sure living in a nominally metric country would provide a higher hit rate, but again, that doesn't speak to the superiority of the metric fastener system. As far as I think I understand, if I had a home shop there, and wanted the same "on hand" coverage I currently enjoy with my "sta...

I have a Dormer metric set covering 1mm to 6mm in 0.1mm steps and another cheaper set covering 6mm to 10mm in 0.1mm steps.

Re: tooling plate

It's easy to cover unused holes, I use teflon baking sheets cut for my regularly used fixtures, masking tape for one-offs.
