Bob I saw that pump plunger and have to assume they had a feed water pump on one side of the engine coming off the crosshead. For the "V" grooves I would suggest using a 45 degree fixture for the milling instead of rotating the mill head The rear of the crosshead looks pretty straight forward...

Bob, I assume you are referring to the crosshead as the problem part as I see no "pump plunger"part ? Wait, I see it now--need my glasses Rich

Bob, Any chance you can post a drawing of the part here ? I have been able to come up with some crazy solutions at work on intricate parts and would like the challenge. Rich That video and your work is awesome !

Stretch I have installed several Hydronic (hot water) systems in homes and have run/worked on commercial Boilers ( 100,200,300 HP) so I think I understand your objectives . according to the drawing, You want a steam boiler to run a pump and use a heat exchanger in the steam system to heat and...

I have some such reamers in my tool box that were picked up years ago at a garage sale or auction. I estimate the size and drill a slightly smaller hole in some aluminum plate ( 3/8-1/2 ") and then carefully ream the hole and measure it and then put a tape wrap with size on the shank. You want...

I am a manufacturing engineer--retired It is very Normal for shops/companies to have custom reamers for their products Some of the reasons are. Special lubrication clearance ( due to load or RPM) Engineering designs that never take standards into consideration of design ( Been there on the...

My belt sander is my 3rd hand , they are awesome machines You need to easily modify them a bit for extracurricular applications Make the table easily adjustable-mark the table- use collet blocks try to eliminate using wrenches , you want fast adjustment here are a few pics and a simple fix...

Not sure of what solder they PM use or offer, but suspect it is a Stay Brite Product ? ( No Lead) Rich https://ch-delivery.lincolnelectric.com/api/public/content/e521e75f45b741e58940da1988c2976d?v=a156575a

Welcome Bug-hunter Are you close to Green Bay ? Rich

Sorry guys to be a dunce here, as I am electronically challenged So is there a way to round off counts and still get back to exactly 360 ? It sounds like there is no "sure Fire" method I cut gears manually , but have a Arduino powered Indexing head (80/1) set up but the old Fellows ( great...

Johnathon , totally agree with your thoughts on the angle grinder , thats a real crude application. And yes, if you modify the shaper to a grinder, it would most likely be a permanent "revision" Rich

The big difference between Surface grinders and Blanchards is that their wheel is raised and lowered to control cut. While Rotary grinders like a Heald , the work piece goes up/down , just like shapers have with their knee to control cut Rich

Very possible .. They are called Rotary Surface grinders --see the "Heald" ad here https://www.machinetools.com/en/for-sale/196374-heald-22-rotary-surface-grinders And you no doubt have seen Blanchard's where the grinding wheel is horizontal I ran a Heald years ago and it does beautiful work A...

guys, even the you tube videos are not right ---in a way ! look at 2:40 (Almega) and 7:40 ( SHopshoe) Look CAREFULLY at the video in each case they pull the telescopic gauge and are NOT perpendicular to the bore ! This is Important .. even ABom said he was off a bit. For some reason ( I have...

A much cheaper method is one I have taught machinists for years . Use a Good (!!!!!!) adjustable parallel- one that has good edges-no dents and is parallel Insert it in the bore and expand it. You can now read the bore diameter Cross-corner with your normal mike. This method also shows taper...

My friend Ron recently passed on and he was a photographer's photographer Having worked his whole life in TV studios. I am a terrible camera user but he did teach me a few things. He cringed when he looked a our hobby engines and parts. 1. get rid of all clutter- nothing in the picture but the...

Very Nice Work did you have the book Early British Quick Firing Artillery by Trawin It is a great book to have Rich It has lots of sketches, but no dimentioned drawings as you mentioned

If you want a good deal---just go to machine shop or job shop auctions There you will find vises more affordable if that is your desire Rich

Determine what kind of work you want to do ? Are you measuring parts with a ruler (inches ) or a mike I am not being prude, but if clamping a chunk of steel or aluminum and milling a slot or drilling a hole is your plan, then Vise quality is minor. If you expect to hold work to a few...

Bob, is that 'freely available " or "available free ?" :) :) Lets hope it's the latter. There is another book by Richard Gibbon That I purchased when in York years ago https://www.amazon.com/Stephensons-Rocket-Manual-onwards-Workshop/dp/1785210637 It has Glithero's sketches of the valve gear...
