This is the one I use on my Super 7. No problems at all with leaking. I would imagine it would be fairly easy to machine an end to fit a ’push’ type gun? p.s. This was not new when I acquired it 30-35 years ago. Doug.

Yes, trying to remove the ball from the bottom of a blind hole would be,’Interesting’, to say the least. But if the ‘cylinder’ was separate from the ‘valve block’, it would be a straight forward operation. Another possible advantage having a separate cylinder would be, you only have to replace...

To improve the surface finish of the pump bore, if the valve end was detachable, you could perhaps try ‘Ball sizing’ - ‘Ballizing’, whereby a correct size hardened ‘ball’ is forced through the bore to correct any taper, and improve the surface finish. Apparently to an almost mirror finish. With...

Some full size diesels used an exposed element glow plug mounted in the inlet manifold to heat the air in the manifold, rather than inside the cylinder itself. Could you perhaps fit a suitable ‘resistance wire’ element loop across / through the manifold close to the opening, insulated at one...

Hi, when you say you have a’knocking noise’ when taking a small cut, have you checked for excessive backlash in the bull gear lock for the back gear. In direct drive, (lathe switched off of course), try twisting the chuck back and forth slightly whilst holding the spindle belt pulleys to...

Found these in a tin, I can’t remember where I got them from, I’ve had them years. The short ones can be attached to the moving arm, the threaded ones used to adjust ‘points’ gap. The assembly was for a spark conversion on a ‘Glow’ engine in the 1980’s. Doug.

Found these in a ’Tin’ I kept ‘glow’ plugs in. The ‘NGK’ plug is obviously a purchased one, the other is one made from the body of a burnt out glow plug, a piece of piano, (music) wire And either a piece of Epoxy ‘Stick’ or ‘JB Weld’. I can’t remember if I made a mould for the JB Weld, or used...

Is it possible with your toolpost grinder setup, to internally grind the cylinder bore, avoiding the ‘spring’ of a boring bar, and producing a decent finish? Then maybe a few strokes with a hone to finish off.

Has anyone tried making a heat treating fixture along the lines of an expanding mandrel/ reamer, using a taper to expand the ring inside a sleeve, heating, then “expanding” fully to force the heated ring into close contact with the bore of the sleeve, then complete the heat treatment? Would this...

How about using one of the “soft blank” morse taper arbours to fit your headstock, you can machine it as the fixture, and know it will always run true again after removing and replacing. Added benefit, no dismantling of 3 jaw chuck to clean out grinding dust. Or if you have a suitable collet...

100% agree, oiled and then on top, water wet kitchen roll, as long as not too many sparks!

Hi Brian, been following this intently, one question? If you compress your rings into a sleeve that has the actual finished bore size, clamp tight, and then machine/grind to a “perfect circle”, you must surely be reducing the o/d of the ring to less than the bore size? Would it perhaps be better...

I’m left handed, but I always drill with my right. My old boss is left handed also. One afternoon he came into the workshop and asked to borrow a “de-burring” tool, the ones with the screwdriver type handle and the little loose fitting replaceable blades. Holding the tool in his left fist...

Before giving up completely, how about another head, maybe from brass, so no separate valve guides/ seats etc. OHV layout with a more conventional combustion chamber. Use the existing valve operating gear, longer pushrods with a rocker from each side to reach the valves? This should reduce the...

Hi, A couple of things, how wide are the seats in the head? If they are quite wide,do you think they may seal better if they were narrower? ( less surface area means spring strength gives more contact pressure). Do the valves have enough clearance in the guides? To allow them to float and seat...

I couldn’t say what to charge, most “jobs” I do are for friends, free of charge! How about asking the lady to provide you with one piece for you to thread to determine how easy/difficult the material is to machine. This should give you a rough idea of how long it will take, and how much to...

For this (Iveco fuel pump) application, imagine a round - I can’t remember the exact shape, flange with three fasteners arranged, not equally, but positioned as if there should be four but with one missing. The seal (“O ring”) never failed, the pump flange distorted on the unsupported side...

If you have reasonably wide flanges and don’t want to use gaskets, you could possibly try a shallow groove in one flange, (like an “o” ring groove) but not as deep. A small bead of sealant in the groove, which then shouldn’t extrude out everywhere but should seal ok. I’ve done this to good...

Happy new year everyone, I don’t know if this would work for you, Rover “K” series engines used a special sealer compound between the cylinder head and the camshaft carrier. It relied upon both surfaces to be machined. No gaskets so no chance of “creeping” between components. I’ve always found...

I seem to remember reading somewhere that the first Bristol sleeve valve engines were rejected by the Air Ministry because they didn’t meet the MINIMUM requirements for oil consumption!!! Bristol had to increase machining tolerances to use more oil. Apparently the boffins decided if an engine...
