Welcome ! Looking forward to learning more about your stamped sheet steel toys.

these are 2 & 4 cylinder VW-engine based pumps we manufacture for compressing natural gas, at well sites. most are powered by electric motors. Some have roots-type blowers, Others are self-powered using two of the four cyls,. And some are powered by 3 or 4 cyl Kubota engines. All but the self...

Thust bearing(s) are easy: for both the 4 cyl & 2 cyl engine we use the same double flanged thrust #1 main brg, at the flywheel end. and we replace the original #3 full-circle main located begind the timing gear, with a modified flanged #1 main brg. We simply machine away one of the original...

My company has specialized in both air-cooled VW & Harley engine rebuilding since 1963, we've built many engines for aviation and or industrial applications. (plaines, gen sets, air compressors, natural gas compressors. IIRC, Global Machine Tool sold a 2 cyl VW for aero use; I think Mosler...

it's interesting to see the use of 3D printing for core and pattern making. Many commercial foundries use 3D printed cores. About 6 -7 years ago I reclaimed/manufactured "stage plates" for 3D laser sintering printers for a company call concept lasers. I had the opportunity to print a small...

My company makes hi-performance big-bore piston & cylinder kits for later model Harley-Davidson motorcycle. We use hypereutectic pistons (~16% Si) so we can run tighter piston to cyl wall clearances - These air-cool cylinders typically have a 4" bore, with short skirted pistons, so to...

fixture ER32 Collet blocks www.amazon.com/Xetilmo-ER25-Collet-Chucks-Block/dp/B0CYFLS1K8 collets are typically sold in sets or separately. ER32 collets have more "range" than a 5C collet. for example 1/2" ER collet will clamp from ~0.460 to 0.500 (usually will grip up to 1mm undersize - but...

NICE WORK ! are you going to leave rocker arm assembly mounting bosses - also bosses on each end of the head for the valve cover bale? just curious... lots of work ahead (no pun intended :-) pics of 1.5l/1.6L single port VW heads I recently rebuilt, and a 1.6L dual port, for folks who...

Looks Great - NICE job! head studs on 1300, 1500, 1600 cc VW air-cooled engine with single-port heads, were 240mm long for the lower row, and 202 - 204mm long for the upper row. M10 x 1.5 threads. In 73, VW switched to M8 x 1.25 threaded studs made of a better grade alloy, that acted more...

Welcome aboard!

welcome aboard, Rick Merry Christmas

for those using water-soluble oil based coolant: it will often get foul smelling, especially in hot weather. Instead of paying $35 to $50 for just 10 to 12 Coolant Odor Control Tablets, use a couple tablespoons of Borax (about $5 for 4 lbs box) Borax is the active ingredient in most coolant...

I save on cut-off blades for my manual lathe by making several from old sircular saw blades.

in a 'round about' manner, your method of balancing the flywheel on the crank is similar to the whip-staff lathe method. good job! Cheers / Merry Christmas

I own a high performance engine shop - since 1963, we have dynamically balances engines, from small 1 cyl to large V16's. Couple comments/tips: - With "unconventional" engine lay-outs, start by drawing a simple a force vector diagram of the reciprocating parts. In this case, the diagram will...
