Part built Allchin 1.5 inch

[derek blakeParticipant @derekblake72550]

Hi All.

The holes still have good thread and the thread down the side of the plate, so I’m unsure how I’d get inside to screw the screws from the inside?

At the moment the bolts do tighten up, so maybe I’m worrying too much yet?

Derek, as Jeff said cut a fine slot on the end of the screw and poke a jewlers screwdriver down into the hole or if you remove thread from the end as I suggested the screwdricve does not need to go into the hole.

Bill it's an internal plate.

Jason I’m sorry for being thick, but you mean get screw down inside steam hole? What type of screw would I use?

Hi bill

the steam hole is 12mm across.bolier barrel 3 and 3/4 inch.

its the Allchin, I’m just a bit confused how I get the screw inside and what screw to use.

i really do appreciate everyone’s time on this,

Hi

studs say bronze which is what I’ve made and 5BA, would it be a bad idea to loctite in these 4 studs? Or could that just spin them out.

[derek blakeParticipant @derekblake72550]

Thanks again for everyone’s time, it’s surprising how this hobby can go from fun to damm right misery for me..all because of 3mm wrong position and I hate things having to be bodged to work.

So made up a bronze bolt, and its a tight fit in the hole, i do wonder if 648 loctite would hold this in really well and be just as good as screwing it in?

i can of course try and screw in from inside but I will have to get some tweezer or something to hold them.

Bill would you try? I will park what I’m doing for now.

would the screw be made from bronze then I guess?

Just an update, have now got a stripped thread.

so I’m going to give up on this engine I think, I’ve ruined a good boiler that I waited a year for and can’t see how I can fix myself as I’m limited on skills, knowledge and equipment.

the bolt from inside went in after 2 hours of trying but went very wonky and when removed the thread was bigger so bolt from above now doesn’t tighten.

oh well I guess I did my best on the build, but I hate bridging things and I can’t see a way out that I can do.

[derek blakeParticipant @derekblake72550]

I guess I could try and make sure one of these, drill the thread out and make it so I can pull through a bolt with a smooth shoulder, i may even be able to loctite in if make it a nice snug fit, I’m going to walk away for now as I feel very disappointed, sorry I don’t know how to rotate picture
