Elmer's #17 Pumper engine Before I put this project on the shelf I figure I will swallow my pride and ask for help!! I am unable to get it to run on both cylinders. I can get it to run on one at a time with no problem, but no such luck with both. I have adjusted the valves so that each cylinder...

I am building the #41 factory engine and am having trouble machining a part. The crank is giving me fits!!! I am not very good at reading blueprints. I can do the outside radius on the top OK but cannot seem to get the inside radius on the sides down. What is the 1-1/4" radius pivot point?? If...

Exactly what I am looking for... Thanks,,

What is a good source for 3" cast flywheels??? Prefer cast iron or bronze. I have been making then from a piece of 3" rod I had but am running out. Thanks, Julian

I seem to have the tool working on a piece of scrap.... That is an interesting site... Cheers, Julian

That is the one I used to make the bit!!! Thanks,,

OK..finally got it turned. Had to use a combination of LH, RH and pointed bits.. My major problem was chatter because my chuck is 6" and will not hold a piece of 3" stock, so having to use my larger 4 jaw with jaws turned around. That makes them stick out so far they would hit the X slide if I...

Thanks for the replies!! I will give the trepanning tool a try.. Julian

Yes, it is a typical flywheel with recessed sides having square shoulders on each side. I tried a 60º threading bit and it did not want to cut either. I guess I need to try different geometry settings for the tools.... It is for an Elmers #17 pumper.

Hello, I am needing to cut a recess on the inside of a piece of 3" steel for a flywheel. I will be going about 1/4" deep. I have tried a couple of boring bits and all it does is chatter. There will be a uncut hub in the center. What type of bit is best to accomplish this??? Julian

Baron and others, After a lot of deep thinking I'm not sure that at my age I want to tackle something like that,,, I will probably just go with the DC motor option, Cheers, Julian

Baron, I want to use it to drive the X table on my mill (24"). Yes you are right...I probably could use a DC motor and gears to do the same thing.. It's just that I plan to get into CNC at some point and this would get my feet wet.. Julian

Hello, I want to build a stepper motor to control a single axis on a small milling machine. I would like to be able to vary direction and speed from a "box" without having to use a PC. Is this doable?? Any help would be greatly appreciated. Cheers, Julian

This vise came with my 8520 I just purchased. Has no mfg,or brand markings anywhere. Any one out there familiar with this vise??? It has about a 4" wide jaw. Thanks, Julian

Baron, Thanks for the quick reply,,, it is not the split pin in the U saddle, it is a hole about 5/16" in the ACME nut itself. If you look down in the hole you can see the ACME screw, JG

Greetings, I have a ENCO bandsaw that the vice acme screw is slipping. It seems to be missing whatever goes in the hole under the flat spring on the acme nut...can someone tell me what goes in this hole??? Thanks, Julian

You guys are great!!! Thanks!!!!

Hope this is the proper Forum for this.. Could someone tell me a source for packing??? I see mentioned Graphite yarn...where can it be bought??/ (in the US) What alternatives are there?? It is for a #17 Pumper Thanks, 'Julian

Thanks for the replies, I have both anvils so I will try combinations of them until I get a reading that will work with the gauge block

I acquired a Starrett #454 height gauge. I have not been able to find a manual or instructions for it online. I cannot for the life of me figure out how to "0" it, the only adjustment is for the vernier.If someone has one or is familiar with the 454 could steer me in the right direction it would...
