Thank you Paul, I’m actually having difficulties with the diff at the moment.

when it’s all assembled on the axial and wheel fitted its locked up, I’m guessing the gears are too tight so I’m going to try some shims to push the gears apart slightly hopefully this will free it up as it’s awful at the moment and won’t rotate.

Sorry I meant the small bevel gears, 3 off

Hi All

Some updated pictures of progress, I have a small question please.

I have fitted the gears in the compensating centre, the spur gears are held on by 1/4 silver steel pins, however I had to ream the gears to get them to rotate but its left ever such a small amount of rock on the gear not the pin, do you think this will be ok? thanks in advance

Thank you Jeff, I could take all the glory but I did decide to get gear guards laser cut but they were still work to build up.

thanks for the question answer Paul, I was supposed to make all my glands to except O rings but for some reason I forgot.

this would have got rid of having to use yarn but I will now have to make the best of it.

regards

Derek

Hi All

so I’ve been quite on here but not in my summerhouse, I will update pictures today.

boiler still being worked on so in the mean time I’ve worked on the water pump which works.

gear guards, cylinder, and some other small tasks.

i have one question please, I’ve brought some graphite’s yarn for the glands on the cylinder. How do you fit this stuff, do you wrap around the rod and push gland in or do you stuff pieces in around rod and tighten gland down?

i have a O ring arrangement on main piston so this advice is for the regulator and slide valve rod.

thank you

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.

18/03/2019 12:20:38

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...

Anytime Jeff! wink

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?

Thanks Jason
