Talking of Expensive Stuarts, I see they are now showing the “Major 10” series, which are the big engines I posted photos of on there stand at the Midlands show. POA

As mentioned in the Stuart Dyno thread. Been There and Done it. Well actually I did the CAD design and someone else printed it. Though it would be easy enough to use the prints as patterns to cast. Also just a couple of clicks and you can have it any size you want.

Indeed, You could look at it a number of ways in relation to Martin’s thread.

Is it dumbing down things as I think Michael is suggesting by supplying plastic parts and metal hardware to put together.

Or is it simply moving with the times and using 3D printing to offer a reasonably priced model to the “toy engine” type collector who may not have machines.  Lets face it Stuarts, Bing, Wilesco etc have all been making ready to run or ready to assemble dynamos for years so the only real difference is the 3D printed plastic parts and making use of affordable motor parts. They have the metal option for those that need it and with all the milling work done will appeal to those with just a lathe.

Another nice one posted today on MEM by someone who has the castings but no drawings, I’ve not heard of the make before.

A bit of progress for those interested. I’ll not show or say too much at the moment as it may go into ME.

Snug fit of new “casting” around the can.

A CCGT insert makes a good can opener

May as well make use of the bearing, not sure about the spherical one at the other end as that used the can as one of the cups, bit of trial and hopefully not too much error needed before I decide.

Hope to use the existing brushes

I did not metion that I stopped short of cutting right through that end as I thought a snag could rip the remains out of the chuck as I did not want to grip it too tightly.

Probably the easiest way to get adjustment would be to have short slots to hold the end cap on rather than just round holes. Though the remains of the motor and magnets could also be rotated in the new casing, pointed end on the lifting eye to lock it maybe?

I’ve not done anything on the Dynamo this week as I wanted to finish a steam engine.

But to encourage others to have a go here is what has been going on on the Alyn Foundry FB group. Old washing machine pump converted to a more period look. Spun up on the lathe and lighting your common or garden 12V “Downlighter” lamp. Showing 5V AC at 2000rpm.
