Thread: Creality 3D For Christmas - Impressions so Far
31/12/2019 12:24:48

I printed a 63 tooth gear for my Myford just for fun .It would be quite strong enough to use for a screwcutting change wheel at low speeds.

The files are here, it meshed perfecly. If I remember correctly it will be very small when uploaded into your slicer, looks like is was drawn in imperial units so you need to scale it up to the correct size.


Thread: Anyone recognise this mains connector ?
29/07/2019 15:43:00

Not much help to you I'm afraid but I have an Efco oven like that. The connector is made of porcelain to withstand the heat. it has a simmerstat in the lead as a temperature control.

There is no access to the other side of oven connector so

replacing it as some suggest s not an option.

I have the original instruction book it's in German.

Thread: chinese hit and miss engine
26/07/2019 08:57:26

I had one of these. It does need compression of course. Make sure the valve push rod is fitted the right way around.

One end is flat and the other rounded. Round end to valve. If it's the wrong way the exhaust valve will not close and there will be no compression.

The only other thing that will give no compression is valves not seating properly or damaged piston O ring.

Compression will usualy improve on a model engine after a bit of running as the valves bed in.

I found the ignition cut out after a short run but this was solved by reducing the battery voltage to 3v, there must be some cut out in the electronic ignition circuit that did not like 4.5v. Engine now runs for as long as there is fuel in the tank.

These models are very well made, I would not like to make one for the price they sell for.

Hope this helps.

I hope that unit is better than a similar one I tried. More air came out of the joints that the nozzle!

Thread: Green Twin Oscillator - 2019 Update

I see. The hole in the front was not visible in the video.

Good work Pat.

I am interested to know what the original engine would have used for as I can't see a way power would have been taken from the flywheel. Any ideas?

David's suggestion also allowed me to send a PM.

07/12/2018 13:14:29

How do you send a PM when the member has no profile?

07/12/2018 12:47:08

I've had this issue before, when trying to reply to a wanted ad the member has left no contact details. How can I contact Mark Lewis4?

I am logged in.

Ian, PM sent. Check your inbox.

This is the Myfordboy video John Reese mentioned. I think this the type of control you are looking for.

Thread: Myford ML10 vs The Rest
29/07/2018 10:30:05

The ML10 is a great machine and capable of turning large stuff. Have a look at the end of this video turning a very large flywheel.

I would not swap mine for a ML7.

"Found my Kennedy at an auction described as a 'firewood kindling cutter', got it for £7 + commission!"

A bit like describing a lathe as a pencil sharpener.

If you want simple you can't beat a Cracker. Plans free on the internet and in it's original form is very simple but can be dressed up as you like.

Thread: How to contact an advertiser?

It would be helpful if people answering ads include their email address when they contact the seller.

I recently had someone wanting an item I had and have been unable to reply to them.
