Unfortunatley Jhon P the pedestal is already made to take a skotch crank which will be driven externally and it has been made as a box so there is no way to drive it internally.I will use stepped pulleys to reduce the speed to the tables provided by Ian and it might need an intermediate pulley shaft to achieve this.Thanks to you both.

Frank

Thanks for the speed tables IanT,the tables were what I was after.

I couldn't stand to scrap my late friends project of a small shaper,he had 80% finished it ,but unfortunateley for me he used two sets of plans.There are no gears involved in his construction and it seems he was relying in the scotch crank driven I think direct from the motor.I think a lot of reduction will be needed and advice on the speeds of these small shapers would allow me to work out the correct pulleys and intermediate pulley for reduction.

Frank

Thanks Tony I will do that.

I am in the process of selling off my dead friends machines.The Ml 7 was made in1957and used for 5 years when owner died.Bought off widow in 1963 and was stood in the agricultural workshop covered until the sonset up a model workshop at home 7years ago and it has been used to make a shaper unfinished so it has had no work.the bed measures the same both ends and also bed depth.I have known the lathe was in the workshop for 40 years unused until I set it up for him on a stand he made for it.It has both half body chucks and tailstock chuck with lever feed to the tailstock a fixed steady and a casting for the travelling steady.A NuTool milling machine with a new X leadscrew and nut which I have just fitted with a set of E32 collets .1989 year of manufacture.A meddings DrillTru bench top drilling machine in good order.A 4" generic bandsaw on wheels .A shop made break.Some advice on prices would be a help.

I enjoyed a Drummond B 1920 for many years only the second owner.I own a small bore Myford and a large bore Myford

and I do miss the cut off on the drummond and think it was an ommision on Myfords part as they continued making the remaining Drummond lathes.When I advertised the Drummond for sale I got no takers and had to scrap a perfectley good lathe for 20GBP.

A Dehumidifier on economy seven, plus in mid winter hesian sacks ,this works well for me .I don't know how much this costs though,I might have to think again with the price rises forecast.I don't heat the workshop so that I don't get fluctuations in temperature which can cause condensation to form,I just dress appropriatley when working.

I bought one of these guns when first on the market then about 90 gbp ,but it has always leakedwhere you arrowed and ptfe has never cured it ,I have resigned myself to a leaky gun.

I have not seen this machine but I used to have to cut from a 100mm log of lignum viti a slice 1 1/2" thick and cut it square to fit in an angle iron support.The engineer who I did this for would drill the timber to take a verticle shaft in a large food mixer and as it is self lubricating they lasted a long time.I don't know if that might be of any help but it worked.I did ask him why not use ball bearings he replied that they always did it like this and it worked so why change it.Cutting the timber did,t do my band saw a lot of good it's hard.

I stand corrected ,but for any level to get a correct fall in a long length of run would have to be dead central on the individual pipes.The level seems to be stuck on drainage ,has anyone got any ideas on the other object.

Sewers were laid to a fall of 1 in 40 so that solids would not be left in the drain .The way to lay drains is to set your staff in the proposed manhole and work out the fall to the next pit with a dumpy level or a water level ,pegs were driven into the trench bottom in the older drainage to pack bricks to lay the eathenware pipes on, with the use of boneing rods , modern plasic pipes would be laid on gravel we never used a level in drain laying apart from seting out.I have done a lot of drainage and have not seen anyone lay lengths of drainage with a level.I don't think that was it's use and the two items are not related .

Frank

The brass slide has a 1" scale on it.Drains are laid with a 1 in 40 fall so that would leave a lot of scale unused.

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.

I have had these tools for years and don't know what they would have been used for .Does anybody know

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.

Frank

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.
