Thanks for the info and advice. The weather here is vile ATM so I am quite happy indoors putting an order together.

I use an old Pentium windows xp tower to drive my router. The computer has a centronics printer port for the interface.
The computer has died. Before I spend time and money fixing it is anyone using...

It is possible to design a compound pendulum. There are a number of spreadsheets on the net which will help with weights and the position. One was on Brian Laws Clock blog a couple of years ago and I...

Thanks for the info.
Looks like I should just keep the old computer going while it is working.
Regards

I dont know what interupts or even if my information is from this century. From experience I have seen early notebooks that struggled to even run Windows 95 so I can imagine they would struggle to do...

Hi,
I have been using a 40 x 30 cnc router for a couple of years. At the time I was assured that I had to use a parallel port desk top and could not use a note book computer as they had interrupt...

Have a look at Draughtsight by Dassault Systems.
It is free for the basic version, they sell upgrades and support if you need it.
This will read and manipulate DXF files. The operation is not too...

I also bought the Sextus plans. They came with DXF and PDF files. You havent said how you are going to use the plans. If you are going to make it by hand you probably would not use the DXF's, only...

I think there is bug in gearotic.
My current project has the default gearotic grasshopper and it works just as you expect.
However when i went into gearotic this afternoon and used 60 teeth and 2...

Mate at the risk of telling you how to suck eggs if you use a four fall sheave arrangement you will need to use probably four and a half times the original weight.
last time I read your clock was...

I do like the Gearotic software. There are two escapements provided and both work. I haven't tried any other gear generators.

The grasshopper was made from dxf's generated from Gearotic software. I was interested in if it would work and it does. All the gear shaft distances look right and the escapement works.
I learnt...

18 odd months ago when I had first started this hobby i made a own design clock.
It was based on Galileo's design. Unfortunately it ran backwards and the hour hand rotated in 40 minutes on 1 kg...

Very nice job. I find these escapements fascinating and I enjoy just watching them.
I scored some marine ply from our club today, they are off cuts from a boat building project. Trying to decide...

I bought plans for the Sextus from Woodentimes in Germany for 35 euro. Wish I had done that last year as I learned a lot from building this clock. David Atkinson (the designer) offers a hardware...

The clock runs almost silently and keeps pretty good time so far.
Will have to dismantle it to do some final sanding.
The arms are Turpintine and most of the rest is blue gum.
Found some floor...

Hi All
What products do we have in Australia to finish plywood. In particular the edges to hide the fact that it is plywood. The minister for home affairs likes solid timber. I understand all too...

on the bottom right of the page is a link to tutorials.One of the tutorials is how to put a clock together.

I think Rusel's is an elegant solution to taking the weight off the main arbor and would not detract from from the ascetics.
I think the arbor carrying the weight, the ratchet, and the first wheel...

7 kgs driving wieght sounds a lot for the frame to support. Do you have a dial indicator and can you measure the deflection of the main arbour when the weights goes on it. What diameter and material...

At the risk of telling you stuff you already know, I saw some YouTube videos of clock escapements made with leggo. My favorite was a mc Donald two leg escapement. In the future I hope to design my...

I have finished Brian Laws clock No 10 and just bought the plans for Sextus. Really looking forward to starting it in about 2 weeks.
Sorry that I didnt do this first. Interesting how he uses collars...

I made a No 10 clock from Brian Laws and it runs for a couple of days at a time, keeps good time as well. The brass covers on the bearing holes were an issue aestheticly. I would make the plates with...

This escape wheel was made in 3 segments with the grain radiating outwards. so far seems to hold up to the stress. Fingers crossed. I have cut many gears from plywood but I think I made a poor choice...

I made an escape wheel and pawl for an earlier clock attempt. So far I am happy with the turpentine. The design was my first attempt at designing and making a clock.

I have made three clocks, photos are attached of two. One is spread over the workshop and is un-photogenic just now.
The first photo isnt really a clock as the hour hand takes 40 minutes to rotate....
