thanks Paul, because they were blind holes I used the first one to mark the second but I’m going make some studs with points as mentioned by Jason for the other glands.

Thanks Jason, I think that’s the best bet.

i will make some tonight, especially as they can be used again.

Hi All

I'm in need of a cheat, I'm making the steam glands this week.

ive made the one for the piston but have the regulator and slide valve ones to make, I turned two yesterday and they were great until I tried to transfer the stud holes into them and I was misaligned.

is there a easy way of transferring the stud position from the cylinder into the rear of the gland ready for drilling instead of trying to measure?

I was thinking of maybe turning some studs with points and gently pressing the gland onto that this transferring a small dent as a marker.

the glands wont go right up to the cylinder so I cant use ink etc.

I just wondered if there was a really simple way that I'm missing.

Many thanks,

Del

Evening all

abit more work on the cylinder done after receiving it back from Ken who very kindly did some tasks I just couldn’t do on my lathe.and I still have no milling machine.

ive finished drilling and tapping the cylinder cover holes front and back, more fixing holes on valve chest cover and attempted first fit of slide valve.

im pleased so far, let’s see if it all works in the end...

Evening All

lots of little bits done on the Allchin, project still ticking along and news that my boiler should be useable and will be finished in due course so that’s good news.

once this arrives the engine can take shape and I can update the pictures.

one job tonight was to thread some bronze bar 5BA and make the cylinder fixing studs.

sorry Jason, just one last question can I use stainless studding with brass nuts?

11/02/2019 13:32:08

Thanks Jason

11/02/2019 13:25:46

Many thanks Jason, but only Loctite if I go for bronze and brass nuts? not stainless studding and stainless nuts.

11/02/2019 12:00:21

Hi Jason

Can you use stainless steel threaded rod and Loctite on stainless nuts and then round them off like yours or is this a failure to an inspector,

Regards,

Derek

I love how a simple question turns into a discussion, its great to see.

so they are your homemade studs on your fowler I see how you made them now.

they look good, I think I shall have a try and see how much stainless hex is however I do struggle with stainless on my lathe for some reason.

07/02/2019 10:45:32

Thanks Clive and Paul for your comments yes

07/02/2019 10:44:00

good idea, thanks Jason

07/02/2019 08:40:40

Hi All

Yes you are correct about Hughes book, I have to say I don't really like the thought of permanent studs incase one snapped or the thread stripped during assembly.

I think home made studs with stainless would work, I think the 2 inch burrell engine kit you can buy from steam traction world uses stainless bolts/studs into copper boiler.

Regards,

Derek

Thanks Jas, I had a look at your fowler album today at work.

Lovely work, if I can end up being half as good as that in the years to come I would be very happy.

06/02/2019 16:27:27

Thank Jason, how about the ones holding steam chest/exhaust pipe on etc?

Thank you

Hi guys

Quick question, I'm about to buy some bolts or studding for the cylinder block.

does it need to be stainless steel bolts and studding or is just steel OK, stainless seems a lot harder to find.

Thank you in advance
