I did balance the flywheels and it is covered at the Home Shop Machinist forum link that I have in my original description above starting at posting #107. The photos don't show up unless you are a member of the forum, but it is free to join.

@@1973JHE u do the work yourself? I’m looking for some to redo my crankshaft one shop said $500 for just truing and no need to balance but that’s hard to believe

Thanks for your interest Travis. This video shows an assembled KR flywheel assembly. The crankpin has tapered ends that seat in the flywheels and nuts to hold everything together. The pressed and plugged style came out with the alloy XR750 in 1972. Nothing is welded here. The link to a forum thread in my description shows more details.

@@1973JHE I'll have to check it out! I came across your video in a Google search "how to true an HD flywheel/crank assembly... As I'm still not sure if I'm going to rebuild the stock one out of my 103 or just buy an S&S , I'm a welder, employed in a machine shop so wanted to know how hard and or time consuming it would be to do it when I clock out... I will be looking at your work site it's just as entertaining for me as it is informative. Thanks again ✌

Hello ozzie, Thank you for your comments! This was the first day of running and I didn't try to warm the engine completely so you're quite correct to notice that the carb needs adjusting.

Hello Patrick, Thanks for your comment, patience, and assistance throughout this entire project!

Thanks for your viewing and comment. I would suggest that as soon as you arrive at the number you want on the readout, you back the screw off slightly but not enough to take up all the backlash. This relieves any tension on the screw and the carriage will not move for a fine cut. Subsequent super fine cuts can be made like this as long as you relieve the tension each time you advance the carriage. This what I do with my milling machine that has a readout and it works quite well.

@@1973JHE problem is that I want my finish cut to be 0,25mm deep. It can shift the slide if there's no support.

Thank you also for your interest and question. As far as the separate videos, every time I stopped the camera it started a new video. There might be a way to continue a video with a re-start, but I just don't have the time to learn more camera software and/or photo editing software. In the 90s I was building my own computers and even got my feet wet doing G code programming so I recognize that the digital age can be great. But I am finding that all this technology can get in the way of performing what I have been doing for over 50 years.

1973JHE I can understand that, I’m still learning my editing software. As I learn more my videos that I’m posting are getting better

@@RockingJOffroad .............as if that's not enough, I have a web site (www.jim-haubert.com) that I can't seem to get to as often as I would like. I'm trying to find a way to machine up more hours in the day! LOL

Thank you for your interest and question. I am pretty sure that I mentioned that this bushing had a taper of .0002 - .0003 inch. I measured this with a conventional mike w/vernier scale for tenths. This is not to say that the written dimension that is obtained this way will be the same if this piece was moved to another shop environment. When working with tenths on the inner and outer items in the same shop a person is in control of both pieces and it is the fit that I was after - not working to a blueprint dimension. Because of the slight taper, I could start the bushing and with each cut, see the progress I was making working up to the fit I wanted. I.E. the busing was my plug gauge.

it depends on the kind of glove, fabric made gloves will get caught easily, not leather, i mean 100% leather gloves without any kind of liner inside.

Thank you David for posting this video showing the danger caused by loose fitting shirt sleeves and a very unsafe way to hold sanding/polishing paper or cloth. Although the video is not very high quality, at 0:52 to 0:54 seconds it plainly shows that this operator is NOT wearing gloves as his rather dirty hands stick out from his loose fitting sleeves. At 3:07 he takes a solid grip of the second abrasive sheet with his thumb under the shaft where the sheet can now provide a pinch point. This leads to the abrasive sheet grabbing and pulling his hand down (counter clockwise) at the transition of 3:12 to 3:13. Still at 3:13 the shaft has grabbed his shirt and his right hand is no longer part of this problem as it is under the shaft. Notice that the abrasive sheet can no longer be seen. This is probably because it is what started pulling the shirt sleeve in and it is covered by the sleeve continuing to wind up on the shaft. A lot happened at 3:13 showing what can go wrong in way less than 1 second.

I guess I went to a different school than the 'Mature' Patriot and any others that have to resort to name calling. I learned that name calling teaches a person more about the name caller than the recipient. I also posted a link in the text along with my video that goes in greater detail should anyone bother to find out more before they state that gloves can NEVER be safe around rotating spindles.

Did not say they could never be used safely. But this type of video can lead to injuries to the uninitiated. As I stated, I have seen what can happen when a glove gets caught on a rotating shaft. No one should suffer that type of injury if it can be avoided. The shaft he was touching was a smooth shaft.

Hi Tamas, Thanks for your interest. I was traveling so couldn't respond sooner. I discussed the building of this machine w/lots of photos and the schematics on the Home Shop Machinist forum. There already was a thread on shop built EDMs and I added my experiences. This thread now a permanent one due to the continuing interest. You will find it here: bbs.homeshopmachinist.net/threads/47972-Has-anyone-made-an-EDM-Spark-Eroder The schematics are in post 98 & 99 but my discussion starts w/post 24. This is a great thread w/lots of different contributors truly from all over the world w/several different approaches to shop made EDMs. Highly recommended for anyone interested. Best wishes to y'all. Jim

Thank you very much. I to am very very interested to build my own home made one, but dont know much. So a Helpful info like yours is GOD send Thank you again...:)

Thanks rick! Sorry that it took so long to reply. This video continues to get far more views than the previous one that led to my posting this. This only proves that people who are now viewing this one have no interest in finding out why I posted it in the first place.

Thanks MazeFrame: Sorry about your strain, hope you get better soon! Seriously though, thanks for viewing and posting your reaction. Glad that you enjoyed it!

+Max Phillips, Thanks Max. Let me take this time to thank you also for your videos and workmanship. I've been to your site and am much impressed!

+1973JHE OOPS! I meant photos

Thanks Jim! That especially means a lot coming from you. I am particularly inspired by your toolmaking projects.

+kooldoozer I have posted a follow up video to illustrate just how dangerous gloves can be with this setup. Be forewarned, I have a bizarre sense of humor!
