this new cam holds the valve open for the correct time, but very different from the one on the plan Any one else found this ?

Regards Phil

Are there any other builders of the Red Wing engine nearing completion ? My cam is same shape as the plan . It opens the exhaust valve at the right time but it wont hold the valve as long as the plan tells me . It should stay open nearly to TDC . Mine closes about half way up the stroke

I am making a new cam with longer opening time to try , but I just wondered if I was going wrong some where

the odd tool is for unscrewing the battery cover isnt it ?

If I wanted to make a sprocket for a 1/2 pitch chain , would the calculation for the pitch circle be the same as for a gear with 1/2 pitch teeth ?

I have borrowed a rev counter , the slowest speed my mill will run is 250 , which looks a bit fast compared with Martin's video So maybe thats my problem

I have ground that flat off several times , but cutter will only last a few cuts , maybe it's a bit soft . great on alloy or brass

I am having problems using a flycutter on my mill . I get rapid wear on the bottom edge of the cutter , Cutting easy machine mid steel , slow revs and slow feed

Where an I going wrong ?

Hello Mick , Maybe that's why ours never worked properly Wrong sort of saltpetre

love that !!!!! mine is just faded green

regarding the chemist sales , back when I was about 13 or 14 . mis 1950s we used to be able to buy sulphur and saltpetre to try and make out own gunpowder . Never got it quite right though ( luckily) flashes and spectacular flames and very few bangs .

. My Mom walked me to school for first few days then on my own from age 5 just like everyone else and we thought it was normal ( well it was ) I did get a lift some mornings with the milk man on his horse and cart ! Happy days !

What is the best metal for a piston in bronze cylinder ? Will aluminium work ? cast iron ? bronze on bronze ?

thanks a lot , the last one looks the most useful

The clutch on my 1965 super 7 , won't free ,it seemed to go fairly suddenly from working to not working Can someone please tell me how to adjust it . the instructions in the book dont seem to work !!

That sounds like a bit of a witch's brew , I have ordered some Rustins , sounds as if it might be good for my kitchen work tops as well

Regards Phil

thanks , I will see if the local DIY has any of that

I am just sanding down a couple of pieces of mahogany for bases for model engines . What to others use for finishing them . making them fuel and oil proof while retaining a gloss finish , one is for a steam engine and one for IC engine

Hello Terry , I have sent you a message with phone number

Phil

HelloTerry I am in Whitchurch , I have built several steam engines not working on a Hit and Miss engine , Like to be in touch and share interests

Some of the drawings I have been working to , have all dimensions in fractions . A part made to 3/16 inch can have quite a wide variation when miked , So its just parts made to fit isn't it

The motor on my S7 gave up the ghost a couple of years ago and I fitted the newton tesla kit . No problems whatever and much better to use than the single phase motor , ( mind you that was goodness knows how old ) For screw cutting , it.s great using the "jog" control and easy reversing . I would recommend it ( not cheap however )

regards Phil
