|Thread: What was the purpose of these tools|
Forget that I didn't scroll down far enough and they are further down.
This was my first attempt at including images in a post and I have not got any words included.I added them first is that correct.
|Thread: Gas engine|
The illutration for the engine are now in my album as I have never added images to my posts I don't know how many could be incorporated and as there are 15 it might be a challenge .

Thanks Jason that valve is totaly different from the illustrated valve and yours looks simpler to make and is the way to go.I will try to get the illustrations on the post.The drawings are done full size and I cannot do cad drawing so unless I do a small scale drawings I can't post them but eventualy I will try.I am still at the stage of working out if I should proceed.
Thanks to all the information given,it seems that it will run and that gives me encouragement to persue this project.
I bought a Stationary Engine magazine June 2021 No567,In which was an article by George Barrett on THe Boys Own Paper Engine.This gas engine was designed by Henry Fuller Hobden in 1895 and was designed to be made on a 3.5' gap bed lathe.Mr barrett was seeking information on this engine as he wished to build it,I too am interested in this engine .I can't get make patterns for this engine as it requires a water jacket and my knowledge of patter makeing is limited,also there is no casting factory nearby.I have done a full size drawing of this engine from the illustrations so that I would be able to make it in stock material.The main question I have is that the given dimention for the combustion chamber at TDC is 1.375" and the diameter is 1.5" with a .5"gas inlet vave on the side of this chamber, this chamber seems huge.The air and gas are forced into an external 4"*.375"verticle steel tube on the cylinder head which is heated by a flame from below .The gas is forced into this hot tube and causes the ignition.The other question is what type of gas to use.I can make it but what is the opinion of others as to it working.In 2016 I think it was raised by George Barrett on the forum but I can't find the coments made at the time.

|Thread: Soft floor and lathe...|
As you are in a cellar.it sounds like the floor is layed on battens on the original cellar floor.If this is the case why not remove a section of the timber overlay and level back up with concrete.
|Thread: wireing of electric motor|
Thank you Noel, I will try that.
There are 4 wires other than the two capacitor wires.There is the earth wire a mauve and also a black wire in one spade connector and a brown wire in a spade connector.The mauve and black wires had brown tape wrapped around them and the brown wire had blue tape wrapped around it. I hope this is clearer.
I have aquired a small motor for my toolpost grinder,but I don't know which is the live and which is the neutral.
The motor is a Remco
This is the information on the motor.Part two 35-2-77RX 240v 50Hz-0.67A 4MFD CAP-2850RPM-75Watts Thermal Protector ROT<------>
The wires are mauve and black in one spade and brown on its own with an earth wire.I have know idea which is the live and am hoping that someone can advise me please.
|Thread: access to magazine archive|
Why am I no longer able to get access to magazines before No.180. I get a message showing that I need to upgrade to a new Flash player.What has happened.
|Thread: Workholding Problem|
I would use a wooden dowell or a piece of brush shaft glued onto the item to be machined with gorilla glue, the foaming type and clamped in the vice overnight.You would have to drill a hole in the dowell to incorporate the spigate. Next day set up in the four jaw and machine.When finished I would saw the wood off close to the steel but in this case you would have to split it off and using an old wood chisel to shave of the adhesive.I learned this from an article by Brian Wood .
|Thread: What Did You Do Today 2021|
My weekend has got even better,I have just got my Rockerthump engine to run.
I had a good day as I have solved a problem on my SX3.This required me to dismantle the machine with the aid of a download on ARC's website .My problem has been the quill which would not return on the spring which I replaced thinking this would solve it and I have always, from new had a problem with the fine feed which would jam after locking, and I had to knock it back to return to the digital reading.I found after the removal of the handle spindle that the fine feed gear on the spindle was jamming on and a lot of force was required to move it.I had to hammer this off and I then scraped it until it rotated freely,on reassembly it worked but the fine feed did not ,I think that the ball bearings in the spindle, lock the gear as there is a shallow groove in the gear collar.I will ring Ketan on Monday to find out how this works.
|Thread: valve diagrams|
I have the timing sequence for my engine. A diagram I looked at, shows the timing on the opposite side of TDC to mine.It shows an arrow for rotation and I don't know wether this is for the flywheel or the camshaft ,could someone enlighten me please.
Kevin,the engine is a Rockerthump By Brian Rupnow.I have built his Rockerblock and that ran a treat .It is stated that the inlet valve opens 20Degrees before TDC.Thanks to all for the input .
I have finished a 4 stroke single cylinder open crank engine and am having dificulty in starting it.Compression is good and I have had the valves out and reground them .I have looked up valve timeing for 4 stroke model i/c engines and some diagams show the ignition before the input valve opens and this puzzles me,is this correct.Any help on this would be good.
|Thread: New Chuck won’t screw on|
35 years ago I had a Myford Ml10 and from Myford I bought a 4 jaw chuck.This would not go on and Myford sent out a man in a suit to sort my problem.He used hand chasers to sort the problem.That sort of service is unheard of today.Perhaps buying the correct hand chaser would be an option to fitting of poor threads.
|Thread: Blown Bricks : Advice please !|
Having been a bricklayer and general builder until retirement. I have never seen bricks as bad as those and remedial work of any kind leads me to believe you will continue to have the problem.Just a suggestion if the wall is sound and it is the cosmetic appearance you are concerned with,clad it with verticle feather edge boards or another choice of material,but don't render.
