Thread: Silver soldering boiler
13/05/2020 09:43:03

Hi Brian the U tube. Do you have to put water in the U part or dose it just fill with condensate from the steam. What happens if the steam gets to the gauge?

Thanks for the information about U bend. It's a bit of a learning curve I just thought it looked ok there I will have to include a bit more tube. What pressure would it be tested to for a working pressure of 30 PSI.

I have silver soldered the boiler. I decided to do it in stages, firstly I soldered the three bosses in the top of the boiler, then I soldered the boss for the level plug and the end nuts into the end caps and then the end caps were soldered one at a time on the ends. I pickled between each go and with a clean and flux on to the next stage. After fettle and a bit of scouring pad it looks ok.

I bought a steel tool storage cupboard from a factory auction for £30.00 plus charges and had a 5mm top with an angled edge to retain swarf and coolant to sit on top which was bolted down. The lathe was in turn bolted through and sealed. There are three shelves inside for storage and it is solid. The electrics are bolted to the end of the cupboard and it works very well for me and it didn't cost a fortune with no vibration as i have seen with some of the flimsy supports that are supplied. Plus I added a second storage at the back for sundries and spare material.

Thread: Silver soldering boiler
09/05/2020 21:59:59

The end caps are held on with the copper bar with bronze nuts but do I solder the bronze nuts at the same time as the end caps which are 12mm lapped on to the tube but about 5 thou clear to allow the solder to go up between them. The tube is 2 1/4 inch diamiter by 6 inch long.

I am almost ready for silver soldering a new boiler for a small engine. The boiler is copper and phosphor bronze bushes. But there is a copper rod from front to back with bronze nuts. Where do you start do I solder the nuts on to the ends first then solder the end caps on to the main tube then solder the bronze bushes the copper rod has to be tight to hold the ends under pressure.

Hi what machine are you using I presume a mill and is there a slot in the spindle to eject the drill with a drift or other means of ejecting tooling. If you use a milling type tooling with side ways load you should always use a drawbar. On my mill I use a drawbar for all tooling as the drawbar is captive and it ejects tooling as you unscrew.

Hi Speedy Yes they are wire pulling pliers. The ring pulls the handles together the harder you pull the harder they grip.

Thread: Telescopic bore gauges.
30/04/2020 08:20:10

I use my telescopic gauges all the time and can get within a thou no problem I would like a set of three point internal mics but SWMBO would not be amused at the cost. Get a quality set Starrett or Mitutoyo I would recommend. There are a few places that you can get a Tele into that a mic wont fit like a recess in a tube.

Mathew I have sent a message. Look at the top of the page when you have logged in there should be an envelope, click to read message.

Hi Mathew I was sure someone was going to answer your question but not yet. I have done most repairs on these but never having to repair this part but if you can put some photographs up it may help. Have you got the handbook and parts list as you can quote the item numbers and see where the fit. If you don't know how to upload pictures there is a help page in the forums list. Go to the top of this page to forums and website FAQ,s then how to upload pictures. Put up some more info so I can help.

Thread: countersinking
29/04/2020 09:55:20

In making special purpose machinery I had a selection of countersinks to suit the screw head as some were close together or an edge etc. We measured the diamiter if the head and got a drill a few thou bigger than the head and reground the angle of the head to suit the angle of the screw. UNC is different 82 deg. Then the cutting angle is flattened to almost zero to prevent chatter and grab. When you use one of these they all look the same even if you go a little deeper and looks professional. There is a slight flat on the edge of the head on most screws in engineering so make the hole to suit.

The fourth from the left is one I still have it was for 10 UNF
