At the expense of the chuck an angle grinder could be used to cut it apart to release the chuck dogs and expose the lock screw.

Sunny Bob I hope you are in good fettle . In an earlier post I got the impression that you would use your router to machine the angled staves using a dovetail bit. As has been hammered home by others this will create problems. If your preferred power tool is a router could you consider cutting...

Hi Mike regarding a circumscribing circle which aligns with joints at 170 mm diameter. What you say is correct and finishing the exterior of the tub to a circular shape would not be possible if 170 mm diameter is required. I seem to recall that when Bob first brought this issue to everyone's...

Jacob you are exact in what you have pointed out regarding stave width for 15 staves located by circumscribing circle of 170 mm diameter. The arc length for each stave is 35.6 mm as you mention. The stave width which represents the chord to the arc of 35.6 mm is 35.34 mm. This gives an error of...

outer circumference of tub is 534.0 mm. Outside width of each stave is 35.6 mm.

Some time ago I needed to replace the tuning pegs on a violin and wish the peg tool would have been available. The replacement pegs were bought via the internet and needed to be resized. This was done using a homemade pencil sharpener type tool. 4 blades are used to guide and cut the peg. The...

BugBear is spot with what he is saying. Beams will have an area running the full span which is known as "the neutral axis". This area or sometimes called neutral fibre does not change in length under loading up to the elastic limit of the beam material (the elastic limit is the point where...

The seating for the rubber needs to be checked for corrosion of rough spots and cleaned up if necessary. A light spring is all that is needed but if your feel it has been weakened or corroded look for a replacement, SIP perhaps. Check the rubber for ridges or lost material and install it...

wallace what is the rating of the fuse you are replacing? It sounds like there is high resistance somewhere. You need to check all connections at plug and motor box. In your position I would renew the plug, fuse and power cord. The environment in workshops tends to be hard on electrical parts.

eaglesatz the way your SIP compressor is acting suggests that pressurised air from the receiver is leaking through the reflux valve into the cylinder. This valve will be located on the pipework connecting the receiver to the compressor and can be serviced or replaced. When working properly it...

If the load is taken off the compressor by leaving the receiver drain cock open does the motor start and restart after being switched off manually?

How is the oil in the compressor? Can you slack the drive belts and see if the motor starts on its own? Also with slack belts are both motor and compressor turned easily by hand?

The Draper web site for BS305 bandsaw has all the documentation that was supplied with the saw when new. It includes setting up and adjustment details as well as parts lists and exploded view. This should enable the correct replacement part to be obtained and have it correctly adjusted to avoid...

A DIY setup for cutting prop hubs. The timber is located on a small pin and rotated against the cutter

Prop No1

scrimper thanks for your advice. If is not too much trouble will you post your prop images to give me inspiration. In passing I am grateful to members of UK Workshop for the interest I have been shown and the information provided.

At last

The hub has been machined with the router and looks OK. 2 blade seats have been cut in it parallel to the wood grain and 2 perpendicular to it. A card template for the blades is ready and I will walk to the timber supplier to buy some 6mm sheet when the wind drops. At this time unfortunately my...
