How's your Shay you were building Paul

Also in the uk you can get BA bolts with a one size smaller head (more scale looking ) Check this site https://www.ekpsupplies.com/ Paul

More bits done, yet even more swarf but then that is to be expected Got the crank sorted out it is a made up one and according to the drawing is held together with high strength epoxy but I have used Loctite 620 and once set drilled and pinned probably not needed but it made me feel better. Also...

One thing you could check (if the carb is as a full size one ) SU's used thin oil as a damper in the top of the piston guide and if the wrong oil (to thick) was used it would slow the reaction time of the piston and give poor performance Paul

I use HPC gears site as they have a calc page https://hpcgears.com/n/left_menu/calc/calc.php Paul

Got going on the Base / fuel tank (yet another bag of swarf to go for recycling) cut out all the inside and did a rebate for the bottom plate ( to be TIG welded in ) then onto my adjustable angle plate to do the 5 degree tapered outsides Paul

Got onto the crankcase which involved a lot of metal removing (thank God for ripper cutters) and at the same time to remember what bits to leave . One thing that came to light was because I had to use a 1/4" cutter for the internals the radius at the front corners interfered with the cylinder...

Hard at it again today, got the inside milled out to give 1/8" wall then shaped a 2.5mm piece for the top plate and TIG welded all round then filed the radius around the outer edge. I can't do the mounting holes yet as these have to spotted from the crankcase, and I want to do the liner as this...

That is another reason for using the correct grade of stainless material and filler material and the correct weld procedure, I'm afraid a lot of people see stainless as a one off shiny material and do not realise how many grades there are, the same applies for machining such as 303 is a free...

Hi Peter yes I never got an answer around 15yrs ago I put the same question to a UK model forum and got loads of you can't do that, so I questioned their reasoning as to why and got the following responses 1. Chloride attack at the water line 2. When a copper boiler lets go it bursts a stainless...

I sent you a PM paul

My boiler was tested to the requirements of the Southern federation Boiler inspectors for 7 1/4" gauge so it came under the UK 2x WP For ASME min, test psi =1.3 x MAWP at test temp, x lowest stress at test temp, to stress at design temp it doesn't state a maximum test psi

Yes I did do all my own welding I did explain in the previous to please excuse the photo's as I had to go onto the uk site that I use to pull out the pic's (from 2010) I will send you a PM Paul

Got a fair bit done on the mill yesterday Paul
