Hi Todd & Joy and everyone who helped good news yesterday July 4th we had it running at last so thanks to all who gave suggestions. We made a smaller power cylinder and used thickish heat resistant gasket material for a thermal break. Then Roy made a regenerator like Todd's and put the...

Hi Todd & Joy thanks for your helpful suggestions we have spent today making a new smaller cylinder as suggested by fcheslop thanks to him too. we have ordered some gasket paper (heat proof) to make a thermal barrier and we have started a new displacer piston to include a regenerator so we...

Hi yes we have sorted the friction and sealing we have made stirling engines before but this one was built when we got it. The displacer was brass but we made one with aluminium as it had worked on other types and we are going to make a smaller power cylinder to put the ratio right. we tried...

Hi Dave could you explain the regenerator please we can't find anything about it a pencil sketch would help if possible, the displacer is aluminium so we are not sure if that's OK. We would be very grateful of your help as we don't understand this engine other types we have made worked very...

It had a plate with holes for water when my friend got it but it got hot very quickly so he tried it with the cooling fins. Do you know of any drawings or plans then we can put it back to water cooled if need be thanks for your help it is appreciated...

Hi Dave I think it was a Polly engine when my friend bought it but it would never try to run as it always got to hot, so Roy it air cooled and it still won't run. When it is spun over by hand it has slight backpressure but we don't know if that's right. We have no drawings but the displacer and...

Hi Tom thanks for the reply I just had not seen any before but I have seen the mortise cutter on a drill it's a square chisel with a drill in the middle but the drill in that was the old type like in a brace and bit. Tom

Hi rodw I have tried the Mohawk drills on steel and they go through very quickly and I've been told they could be for stack drilling several jobs at once the pilot bit on the end stops them going off course but I don't know for sure. Tom ,

Hi Guys thanks for the info all I know about them is they were from a closed down engineering works and were with a load of reamers, taps and dies I bought Tom

I bought a box of mixed taps dies and drills off e-bay and in it were two types of drill bits that I have no idea what they are used for so I hope forum members can help. The first photo gold coloured drills marked Mohawk and have smaller drill ends like a pilot drill the other has a spiral...

Please has anyone any ideas where I can get measurements for the gears on my Bassett Lowke 3/4" scale traction engine and also has anyone a set of drawings for one as I am still short of some parts of the drawings. Any information will be gratefully received. As I am at a standstill on the...

This is the Traction Engine as I got it as you can see it needs a lot of work the bottom picture is after cleaning.
