One consideration that may not apply to this application ... if high precision and/or consistency is required between parts. Letting the part(s) "age" for a few hours before final turning is helpful. This was learned when making go/no-go gauges. Dimensions would creep a couple thou overnight...

It's always a good feeling when you get all the bits working together and running. Congratulations!

Here is another option to try - Canadian vendor too! Or, you could of course replicate the design on your own. Rotary Demagnetiser - Gray Drafting and Design

If you are going to be in Dunedin anyway and even remotely interested in aviation, visiting the Croydon Aviation Heritage Centre is a "must do"! https://www.croydonaviation.co.nz/ If you go, say "Hi" to BFH and AKY from me ... fond lifelong memories of flights in both. I even built a model of...

No, it’s just going sit pretty and get a run once in awhile like all its “stable mates”. It’s running on straight methanol. It burns clean, smells like an old sprint car and doesn’t gum up the works. It’s a little fussy to start when dead cold but the tiniest bit of warmth and it starts right...

Thanks everyone for the kind comments. Craig - no I haven't checked the speed (my old Royal optical tachometer is out-of-service). I am pleased with how smooth it is throughout the range though. When the timing was too advanced to idle it hummed along at a frightening clip. Now that a better...

If you are worried about space ... How about using your wood skills to build a storage cabinet "around" the drill press stand to use the space under the table. Something with lots of small drawers on casters? Oh, and No, don't get rid of that drill press ... you'll be sorry.

Happy with how the latest shop project turned out. It's a 32cc 90 degree V-Twin to a design by Jerry Howell, a well known model builder and designer. Although Jerry is no longer with us, his son still makes the collection of drawings and hardware available. It was a fun build to a very nice...

Another option that may do what you need is CamBam. It runs locally (i.e., NOT cloud based) and uses a permanent license. I think the recently added MOP imports at least STL files. Unfortunately, their website seems to be unavailable right now. Hopefully it isn't a long-term issue ... I've...

Congratulations on getting it done and running. Could be an intimidating beast to setup with all those moving bits. Mesmerising to watch run though I'm sure. Good on you for sorting through all the threads, updates and changes on the MEM forum! Charlie

That's for sure. It shutdown in 2008. Congrats on the winning bid!

Shame to see that surface plate uncovered. I bet that used to be some of "my stuff" that got moved to Universal when the O-I glass plant was shut down. (I was the QA Manager at O-I for a number years ...)

I think you cursed me ... I did in fact break a 2-56 tap this morning! First one in years. (Probably should have replaced it a long time ago.) It must be the first version of the book. Copyright 2005; 4th printing.

That's a dickens of a way to find out that a long-time employer "down the street" is shutting down. I guess it was only a matter of time after shutting down "our" glass plant in Lavington.

Anyone want to "have a play" with an EDM to the Ben Fleming design? I built one a number of years ago. It has been used a couple/three times but is sat on a shelf since. Need to start moving on things I don't use anymore... I'd rather not ship it but will willing hold it until you can arrange...
