I wonder if you will still be able to buy spares /accessories etc for a Far Eastern product that is 70 years young and will it still be useable? At the moment the proof is the premium that brands like Myford ,Boxford and Colchester etc still command.

Daniel , there will be 6 points of contact as it rotates and each point comes into contact once per rev. Out of interest I have made two of these , one to my own design and one of Hemingways design and both work well.

surely it must be quicker and easier to part them off.

Good to see you've changed your mind about a total clearout cos once their gone their gone!!!

Manganese bronze is good for cast iron repairs.

As Peter says the principle is very simple but perhaps more easily understood as the action is akin to skiving with a wood chisel type action.

I presume you mean CLARE, if so quite well known. Google is your friend.

I have a set of Castings fir something similar and my son has the finished article and very nice it is too. This version is counterbalanced not spring return and motor is mounted similar to GHT pillar tool albeit a bit larger . I also have the original Indian ink drawings on tracing paper dated 1975. They were drawn by a friend of mine now sadly gone.

My house is 74 and they are all 3.5mm MK patresses so that makes it 49 years, my how time flies!

Model aero is machine to within a thou and hone /lap the rest, just finished a 0.1 dragonflea but its a tad too small for me ,working on a glow humbug at the moment hope you have success with yours. somewhere around 1.5 to 2.5cc is a nice manageable size.

I use delrin / acetal for making small gears 6/8mm dia and have never had a problem with drilling and reaming holes to size as well as bobbing teeth, the whole idea of it is that it is an engineering plastic known for its ability to machine to reliable dimensions. Are you sure that's what you have ?

Lubricate

can you not sandwich the spring steel between two 4mm strips of steel and mill with carbide cutter. if stacked they will come out very clean

Definitely lee I had the same with a bike laid up for 8 years, did fuel lines and carb. It took a lot of cleaning using gunk and fresh petrol.

Had a similar idea to Mike but these are for petrolheads!

I have done 4 machines so far with magnetic scales from Mdro and EMS and all work really well, have also fitted cheap scales and read outs to a sherline mill and they work as well (bracketed was a bit of a nightmare). As people have said before it gives greater confidence and also speeds up the process.

Watch out, watch out there’s a thief about! TV licensing scam email this morning asking you to open a portal ha ha. Be careful out there!

hydraulic oils are not water soluble I Have 4 machines in an unheated garage that use hydraulic oil as a coolant and do not have trouble with rust even when the temperature changes dramatically and condensation is on every thing. I get mine from a local ag engineers after they have done oil changes.

I very much doubt that the crew holes are worn as they are through hardened. I will try to measure my screws and see what I come up with.

Fine pole chucks have the focus point closer to the chuck face than the coarse pitch version.
