When I have tried to use the hand wheel on the end of the lead screw on my aged S7to move the cross slide with the half nuts engaged . it's always difficult to move because it turns the screwcutting gear box as well . Just been cleaning and oiling , and I cant see any way of disconnecting it . I never use it for that reason . Is this the normal situation or am I doing something wrong ? Just what is the use of that graduated hand wheel ?

Regards Phil

hello Jason yes its for a old Bluebird 45 engine , the needle valve . I have one for a pattern . I was told by an "expert" that it would be an AF , I could have a try on the lathe but sure to need a die to make a clean finish

Thanks every one for information

I am having problems with a fine thread , the dia is 0.156 inch ie 5/32 The pitch fits on my metric gauge marked as 50 , which I assume is 0.5 mm pitch, but seems finer than that , too fine to count till I borrow grandsons microscope . The screw is an adjuster in a model aeroplane engine ,

any thoughts ?

the J&E looks interesting , if it was reduced a bit

sorry , I should have indicated that I am after an IC engine , made several steamers , and just fancied a change , but the casting sets are so expensive

hello , has anyone come across plans for an open crank engine made from bar stock ?

hello , are these plans freely available please , I should like to have a go at one

has any one built the Little Wonder engine ? Can anyone explain how the governor works please . The drawing isn't very clear .

just the thing for us oldies , if anyone is disposing of one

I have sent for the ARC one . see what that looks like

Thanks I will follow up some of those , Problem is the advertisers don't say what the sizes are ,

can anyone please recommend a supplier of a small tapered square file of decent quality ? I need to file a hole a bit less than 1/8 inch square

regards Phil

Can anyone please tell me what the pressure angle in on !960s model Colchester Bantam change wheels ? 141/2 or 20 ? I have read confusing information Regards

Thanks for the help , I have a working Tich with a blow down valve , but I have acquired a larger boiler that I would lie to experiment with . It doesn't have a BD valve . If I try to silver solder a bush in now is it likely to ruin the boiler ?

all the best for the new year , may your sheds be always dry . The plans for the Tich boiler don't show a blow down valve , some photos show them with some without . Is one needed or is it optional ,and could one be fitted to a boiler already made without damage to the integrity . Regards Phil

I have a Bantam and a Myford , The Bantam will do anything the Myford will do and take bigger pieces and I find the direct reading on the cross slide much easier to cope with than the Myford , Hardly ever use it these days , unless the Bantam is set up for a job , I did change the motor for a single phase one and made up a clutch by slackening the drive belt ,, it has worked well for 10 years

thanks for the information , I heat treated them today with slow cooling and am very pleased with the result , , gapped them and they fit perfectly . remarkable !!!!!!!!!!

when tempering home made piston rings should they be cooled quickly or slowly ? U tube videos show both methods ,

regards

yes , that's the drawing I am working from , scaled down , Its for a big boiler Tich . Thanks for that link , very useful . ( and interesting )

Thanks David , I will carry on with that set up then # I take it that the valve seat is bored straight through and not tapered ?
