Machining some miscellaneous parts. Machining piston. The smallest grooving/ parting off tool I have is 2mm wide. So piston ring grooves dimensions are different from that given in drawing. I will not be able to use the teflon piston rings provided with the kit. The counter bore for piston rod...

Some more machining on base. Cylinder seating area has to be spot faced. Same was done by a 40mm facemill. Main bearing were bored using a 10mm dia and 200mm long endmill. Regards Nikhil

Machining flywheel My Sieg lathe has a belt and pulley arrangment for changing speed. Lowest speed is 125 RPM. Flywheel was turned on this RPM. Some mistakes were made. Flywheel was centred by indicating on outside rim. So now when the engine runs outside rim is running true but the inner cast...

Machining crankshaft The drawings ask for 3/8" crank pin and crankshaft. I don't have imperial drills or reamers to bore out the main bearings and connecting rod to 3/8". So the dimensions were changed to 10mm. The drawings also mentions about crankpin turning jig. I didn't have any suitable...

Here are some pictures of machining cylinder. A steel rod fixed in the drill chuck is insurance during facing operation. This is my angle block for machining steam passages in cylinder. Regards Nikhil

Here are some more machining photos. Machining base. Regards Nikhil

I ordered these castings from US about 3 years ago. One of my friends brought it here to India. Saved some on the shipping cost.:) I followed the two series on YouTube on building of this engine as best as I can. All the dimensions were changed from imperial to metric. All the fasteners were...

Well murg and moorkh are totally different. Murg is chicken and Moorkh is a fool/ dimwit. So I dont know but did you here it properly? I dont know about the book. Its only copy that (I have 2pages from it), As I saud I would like to copy the design concept of that compressor and make it with...

Yes definitely. There is even a word to describe it. JUGAAD. This word even made an entry into the Oxford dictionary. In India most of the shops are privately owned and not some big chain franchisee. So the shops only stock hot selling items. No owner will cut his margins by stocking on items...

I have downloaded this from some website. Its from some old DIY book. I don't think I am allowed to post material here that may be copyrighted or generally downloaded from some dubious sites. Its very simple reciprocating design with ball valve for delivery side and inlet valve on piston itself...

My home town does not have many industrial manufacturing units or big workshops. We have some lathe shops that cater to mostly automobile repairs. We have two shops that sell all the common cutting tools required by machinists. There I can get a 8mm countersink for about USD 2. So countersink...

I am thinking of making a small compressor myself. I got some drawings from internet for a small workshop compressor. I will try to at least copy the design concept if not actual dimensions from it. You ask very tough questions. I am sorry for faulty part you received. I am not into production...

Hi Richard, I machined this engine. Its a PM Research #5. It was my first engine from a casting kit. Only thing not original is fasteners. I did replace all the fasteners in the kit with metric ones. My thread is here...

Hi Happy to see a fellow Indian getting into hobby engine business. Regards Nikhil

We use the below type of evaporative coolers in my part of India. We have dry hot summers with temperature going up to 48C. These work best in low humidity conditions. We call them desert coolers. Three sides covers are made of two layers of mesh with dry grass filled in between. This cooler...

It lives. o_O 👏👏👏 I used a car tyre inflator as a compressor. Initially when I tried to run it, air was leaking from exhaust all the time. My slide valve was tight and not "floating" as Mr Keith Appleton has explained in his serval videos. I opened up the slot in the slide valve so that it was...

Thanks Martin, I will have a look at their website. Regards Nikhil

Hello After I completed my PM research #5 engine I have gained enough confidence to go for another engine. I have a PM research #1 kit with me. I am watching all the YouTube video currently being shown about machining the above engine. I was thinking of ordering a hot air engine casting kit...
