    CH drain down help

    If you have a small tank in the loft (a Feed and Expansion (F&E) tank), I'd strongly recommend cleaning it out before draining the system. If you don't you will wash all the muck in that tank into your pipework and potentially the boiler. Isolate the supply (turn the water off or tie up the...

    CH Circulation pump (?) fault diagnosis

    1. If the pumps are hot but the water is not I'd suspect faulty capacitor(s). With this problem the rotor won't start, and the pump acts like a coil and gets hot. 2. If you are comfortable working with mains voltage electricity and have appropriate experience, try 2.1 Disconnect the pump...

    Naerok mill - cutting out

    I've got the same mill. A while ago it started cutting out, but would work if you held the start button in. No smell of burning. Unplugged it and used very fine sand paper to clean the contacts in the starter switch. Plugged it back in - no more problems. Worth a go!

    One for the plumbers please

    1. As you know, you have to put a pipe insert into any plastic pipe at a connection. 2. If you use Hep2O pipe, their standard inserts are fine. 3. If you use JG Speedfit pipe, they do two types of insert, "Superseal" (with added O rings like post #4 above) and plain. With compression fittings...

    Need some guidance with my wood floor

    1. Many flats have a covenant in the lease stating the floors MUST be carpeted. If you remove the carpet you may involve your landlord in a dispute with the freeholder, and he / she may seek to recover any associated costs from you. 2. Most rental agreements state that you may not alter what...

    Do fancy spiral thicknessers just work without tearout?

    For Doug71. If the feed has a separate three phase motor, then it could be speed controlled using an inverter. If the machine is directly off a three phase supply, then a 415V 3 phase speed controller would do the job. If fed from a phase converter, separate the supplies to main and feed...

    Adding potentiometer to bench grinder.

    1. As Yorkiguy has said, it's an induction motor. 2. The only way of varying the speed is by varying the frequency. This requires an inverter, but these only work on three phase motors. 3. Even if you could fit an inverter, it would be extremely dangerous unless you found a way of limiting the...

    Bonding Nylon to Metal

    Another option might be to make up a filler piece (wood?) to fill the central gap, then accurately fix the slider in place on the guide bars and fill the space between slider and bars with Turcite or similar. Its designed for machine sliding surfaces.
