Trevithick Dredger Engine- the flat end
The 6″ vertical boiler has had its first brazing session, and has been put aside while I wait for the boiler inspector to give the “go ahead” so I can proceed to the next brazing session. I am told that the first braze is the most difficult. The next braze is bigger, but the components are all on or near to the surface, and it is consequently more straightforward.
So, while waiting, I pulled out the Trevithick Dredger Engine, and decided to make the flat end plate and flange. These are machined from LG2 bronze disks 13mm and 8.5mm thick.
What sort of clamps are you using ?
Second picture down, where you’re CNC drilling, – look like some sort of camlock ?
Hi Ian, I do not know what they are called, but I believe that they are used in aircraft manufacture. Very quick to adjust, and can be set for repetition by tightening the lock nut. Yes, a cam mechanism. Bought a box full of them from Ebay US when postage was affordable. John.
Thanks John, I’ll see what I can find.
