I thought of that, but forstner have only cutting face. One I was thinking of have normal flutes like a twist drill, but flat cutting face with a centre Brad point. Nearest I have found is a dowel drill

I need to drill some flat bottom holes in hardwood. (12mm diam) Ones I used previously are a bit like engineering end mill bits. Is there a particular name for these bits …. So I can find one on-line.

A neighbour just donated me 2 VGC twin 6' fittings complete with Phillips 75-85W tubes, While I have the slimline tubes & fittings in my garage, I could utilise these over my workbench. Should I just use as is .... or is there an adapter to use slimline Tri-Phosphor tubes, I can see an adapter...

want to have as thin a 'protection' as possible

Often instrument cases are made of wood , but have a black 'felt' coating over all the compartments to protect the instruments .. Typical (but old) such case in sample pic Is this 'sprayed on' or is it a glued on fabric ? .... need to make a few storage boxes and need to have them lined...

If you don't like my post please feel free to scroll on by, there is no need to be discourteous or insulting this is an open forum. I am not clueless, the sketch is done using what I have to hand, (PowerPoint), I don't have access to an electrical drawing package to produce using IEC 60617...

Others have understood the ask ... apologies if you are not understanding or possibly reading too much into it. The fan is fully controlled by the controller, the output of which is 0 to 12V, and as its variable speed it can be any voltage up to 12V ... I have measured and at full speed it is...

I could not bother with the LM393 comparator … and instead use a simple 741 op amp

Taken suggestions onboard Now it looks like this sketch I know I need to use current limiting resistors for diodes ... not sure if I need any diode protection for relays, normally add an IN4148 across the coil. Existing physical switches are unchanged just now driving relays as per suggestion...

Its DC 0 to 12V

need it to activate display from 1V to 12V ... hence a comparator was my thought.

Agree and I could use a fixed 12V for the relays, that would resolve switch issue, still have to detect that there is voltage to fan …. And that can be anything from 0 to 12V I thought of a voltage parameter … but happy if a simpler way.

It’s on the sketch …. The controller is not important, it provides a power voltage as explained … 0 to 12V to the fan This feed is a simple 2wire output, with the 2 switches in series. i would like to be able to know when there is any power feed to fan plus the state of the 2 switches

Project I would like to identify the state of 3 switches, sw 1, 2 & 3 and when power is supplied to a fan …… so 4 indicators – assume these would be LED. I.1 – I.4 Sketch is attached. The controller is self-contained controller providing Bluetooth, Wireless, time & temperature functions...

It was quality glue, and pressure on joints for 24 Hrs. So you may be right.

I was thinking dowels would help hold the 2 halves of handle together, if it won’t them I’ll not do it. I do make my own dough, several types of it. plus Nan bread, pitta bread etc.

I do t want to make handle thicker, thanks for suggestion.

Appreciate glue might not last that is why I want to reinforce with dowels. I'll have a think about ss nut & bolt, but not really the way I want to go - I want to keep as wood, and metal could get hot.

I use a wooden Pizza peel - birch ply - Does the job well, but handle is too small for comfort (for my size hands) I had some offcuts of 12 x 60 Ash , so cut a length glued on some short shoulders to give me a 'T' shape and routed out the shape of the existing handle and inset that and the...

I did try … but asked here in case somone has personal experience
