Hi Anyone ever tried engraving ceramic tiles? I have just engraved a pattern on a glazed ceramic tile on a CNC machine with a diamind drag bit, should the surface be sealed and if so, what should be used. The one I have done will be used as a trivet, but I would like to create some more for...

The hollow dowel is a shaft for a wooden clock which needs to take a 6mm dowel inside, the hole actually needs to be about 6.1mm to allow the inner dowel to turn. As it is wooden clock, I'd rather not use steel. I do have access to a hobby pillar drill but the distance between the Chuck and the...

Can anyone suggest the best type of bit to drill 6mm diameter holes in some 10mm hardwood dowel. The dowels are 180mm long and the hole needs to be down the whole length. What type of should I be looking at Twist, Auger or something else and can anyone suggest a good approach to getting a good...

I came across the Tremie method whilst looking on the web for a solution, but I had not come across the Bentonite one. Both seem a bit complex to achieve for a comparatively small hole, especially seeing as I am mixing and pouring the stuff myself. I think I am going to have to go with the...

The hole is currently about 350mm deep with water so it has gone down a bit (picture) I think that pouring even dry mix in could cause it to separate out.

I dug most of the hole a few months ago and it stayed dry. With all the recent rain, the ground is saturated. I have been pumping it out so I can get the hole to its final level, but after a few minutes the water is ankle deep again and overnight it fills to about 500mm deep. The top is loamy...

I want to lay a thick concrete slab to act as a base to a telescope. The slab is to be about 700*700*600 deep. I've dug the hole to the correct dimensions and now ,because of all the rain, I have a fish pond! Is there any way I can pour the concrete without waiting for the water level to drop...

Thanks for the advice everyone, been really useful. So now I'm a bit stuck. Brick piers are obviously out of the question (unless there is some way of reinforcing them). Can anyone suggest an alternative that would be more suitable. Ideally I would like the fence to sit on top of the wall as it...

So to clarify, the problem would be with the panels tearing themselves out of the fixings rather than the piers themselves failing. I am planning on building the panels myself they would be 18 X 95 mm hit and miss boards with 50mm gaps running either side of 25 x 100 mm batons running top and...

Hi. I'm after a bit of advice on building some brick piers. I have a concrete block wall at the rear of my property. It varies between 3 and 4 foot tall and is 1 block (9 inches) wide. I want to increase the height to 6 foot all along. My idea was to build some brick piers on top of the wall...

Thanks for the replies everyone, probably going to go for the Travis Perkins one

No, 600mm is correct. It's a foundation for a telescope pier. Most of the shed base will be around 100mm thick. But part of it will be 900x900x600

I want to lay a thick concrete slab(600mm in places) as a shed base and intended to use a maxibag of ballast and cement. Many builders merchants seem to offer only ballast with small stones. More like a very coarse concreting sand, such as this from Travis Perkins...

Thanks for the ideas everyone, I had thought of slider rails but it was the clamping down that I was struggling with. I don't really want to be messing about with bolts if I can avoid it, especially if I need to clamp it down in the dark. However I did a Google of overcentre latch and all sorts...

I need to build a new shed in my garden. Only a small affair, about 4x3 foot. It's going to stand on a concrete slab. Straight forward enough you may think. Now the interesting bit. It's to house a telescope so I need to be slide (roll) the shed out of the way to use the scope. We are in quite...

333rocky333 The old fittings only had two screws about 1.5 inches apart they didnt really support the light properly which was 12 inches in diameter. There was a marked gap between the fitting and the upvc. ban-all-sheds I did look at these but there is a rather large hole in the upvc where the...

SFK good suggestion. I should of thought of that. Ban-all-sheds The house was about 15 years old when we bought it and the upvc was already fitted. Ive drilled some small holes to see whats behind and its just fixed to the rafters so long screws are no use. Im going to try self tapping screws...

Yep. Thats great. Ive just taken another look. Now im not sure if the upvc is installed over wooden boards or directly to the rafters. If over boards i may just get away with some long screws. I think i am going to have to drill some exploratory holes.

So this would be glued(?) to the front of the upvc then the light fixed to that, spreading the weight over a greater area?

I need to replace an outside bulk head light as the old unit has failed. The light is to be attached to a upvc ceiling in an outside porch. Needless to say, the mounting holes are in different places on the new fitting. Are there any particular wall plugs for attaching fittings to upvc as the...
