Thomas and Bill, I tried for weeks to find a local source for Petrobond. I contacted three commercial suppliers. I got the contact information for one of them...
Bruce, I think you are asking about the casting hobby and the Gingery groups. They do not discuss EG except in passing. The foundry group has a lot of traffic....
Hello Shannon I am not sure about being able to grind the concrete to an accurate surface. To get an accurate surface, you are talking about holding 0.001 or...
... Isn't this one of the reasons why some big CNC machines have gone to "slant bed" designs, where the ways are parallel to the ground, but the slide runs at...
Years ago I began a metal casting discussion group....... when there was no such thing on the web and virtually no info to be found. Paul Encoyand helped...
Hi Shannon I am quite aware of the DIY-CNC group and CNCZone being a member of both for quite some tine. I also posted much of the EG info in the Open Lathes...
I don't want to start a new thread to share this simple idea. If anyone thinks it worth it, please start your own. Would it be practical to use angle plates as...
"If you want something done right, do it yourself" unknown. Good advice, we all have different skill sets, united we have many skill sets, more tools than Tim...
Hi Gordon I have one of them ,angle plate. it is a handy tool to have for stuff. Â You are right about them ,Enco sells them cheaper than you can make them. Â ...
... Let's assume that you want a 2" OD spindle and tapered roller bearings. This means that any hole must be at least 3" in diameter. Now, let's also assume...
... We tried that, the downstream waterwheels were "starved" by those upstream. While a river can provide free power, it is finite and extracting the power...
The river is a mile wide here, 1800 miles from the gulf. The main channel is about 200 yards wide and must be kept clear of stationary objects. Between the...
If you are just looking to slice and dice PDF files, and are stuck with windows (real OS'es come with better tools for this) you can obtain pdfcreator from...
I didnt mean to mount the spindle in them, just the ways. You can do better than $40/ft, even if you pay your seld 50/hr for looking in the junkyard....
Hello Gordon I think Imust have missed something in this concept? I dont understand how to use th angle plate for a machine way? Â Keith Deep Run Portage Back...
Angle plates provide a easy way to have a hole exactly perpendicular to a surface using common equipment. What ever you use those holes for is fine, I just...
Hello Gordon  On the same idea ,set of 1-2-3 blocks are handy for setting up work on a machine.  Enco sells them for $10 a pair sometimes.  Keith Deep Run...
The rods seem to often be measured in inches and not in metric sizes. This means that standard size bushings would fit and be a real money saver. Could the...
... That would depend upon the hydraulic shaft!! If it is hardened and chromed (or nitrided) - - good luck. I can give you some ideas for procedures - - its...
Thanks Darald I think I went too far trying to save money! The hardened piston rods would be fine for round ways but 24" of 1.5" shaft and stock size bushings...
Hello Pat  Why have three shafts?  What is the one turned to 1.25in for?   A piece of DOM tube could be used for the shaft, it already has a hole in it. ...
I've seen commercial dryers that chain-drive the drum. Belts get you the initial reduction, the final chain gives slow speed with lots of torque and no...
... My comments come from actually repairing and making hydraulic cylinders. I think that the biggest rod I worked with was about 3.5¨ OD. I have also ...
Hi, Why is belt slip a problem? If the belt system is properly specified and implemented if will transmit the required power with no problems. The Industrial...
Hi Ian I think slip was a problem for at least 3 reasons that I would change if I could. The brackets for the pillow blocks were not made strong enough to...
Hello Pat  You do not need very large pulley to work. the numbers are with a 1725RPM motor  a 2in on the motor a 7in on reduction shaft gives 3.5to1 make...
