LOL, there is that! Our 4 fur kids are in heaven with several each. I've got my "rejects'" in several places around the apartment now and Fray and Nimitz will paw one over to me if I am sitting close

Re: Flywheel for Stirling engine
The "best" way will depend on the operator's preference! If there's a machined surface anywhere on the flywheel you received, it's usually handier to start by using it as a reference for subsequent

Flywheel for Stirling engine
I am a newbie with the lathe and started with a Stirling engine. What would be the best order of operations for the flywheel and how do you make both sides parallel? Any advice would be appreaciated.

Re: First prototype of the laser edge/center finder done!
Hi, Well I'm not a physicist although I am an engineer of the electronic variety. My thinking is that the laser wavelength is around 600nm from memory and will readily detect edges of quarter wave.

John, You and Roy hit the nail on the head. I'm cutting an approximation of a 1.5mm metric thread...something I've never done before. I thought that engaging the half nuts at the same number on the

Re: First prototype of the laser edge/center finder done!
Hi Roy, Yeah, but once Vikki's commercial number from MM arrives I think she'll find new games to play. Vikki's had the fun of sussing out how far you can push a $1 laser and it's been an interesting

Re: Thread cutting mystery...
What thread pitch are you trying to cut? The threading dial only aligns for multiples of 1/2 tpi; if you're doing a metric approximation (with an SAE leadscrew) you'll have to keep the half-nuts

Re: Thread cutting mystery...
If nothing is slipping, it may mean you have the gears set up for metric threads. How many tpi were you trying to cut? How many tpi did it actually cut, as measured with a thread gauge (no estimating
