Folks,

I thank all that contributed to the thread I started a few couple of weeks ago, "Need some help for our club". With the additional help of Don Geiger and John K. Jordan, I now have a very good working prototype. It's based quite a bit on King Heiple's design. Exceptions have to do with sizing. I've got this sized at 9-1/2"x19". This is so a club can go to a big box home supply and have them simple cut strips of 9-1/2" plywood and yield about 12-1/2 bases with little waste. Then using 1-1/2 lumber the rest can mostly built. My goal was to keep it simple so a club could make kits for new turners that don't or can't afford a Wolverine style system. Basically it turns into just using a chop saw to cut the pieces down then screwing it together. Although t his one was built for free from shop scraps, it can be done by a club at a cost of $10 to $15 each. This includes a platform jig to do scrapers and bits at 60 degree's fixed, a jig for skews and one that can do roughing, spindle and bowl gouges. I still lack that handles to go on the bolts that lock down the arms and gouge jig, but their coming.

I'm thinking in a workshop setting, it should take about 2 hours to assemble. Then I intend to have new members tune up their grinders doing the Don Geiger method to true the wheels. If anyone is interested, I intend to write an instruction PDF for other clubs with pictures.

No problem, I'll also send you the PDF instructions with pictures on putting it together. I want this available to all clubs, so it'll also be on our 2 websites. tristatewoodturners.com and cumberlandwoodturner.com

Re: Rikon wheels wobble

Dave Paine

I may have the same Rikon grinder. Mine is a 1/2HP slow speed. I have two local friends with the same grinder. All of our grinder wheels have a LOT of wobble.

I looked up the Don Geiger page. His method may not work for the Rikon.

I took mine apart to find the problem. The shaft has too small a registration shoulder. Likely Rikon saved money by using smaller diameter shaft.


The shaft is a loose fit in the 5/8in diameter holes of the wheels.

At the time I did not have any metal stock to machine a custom washer to provide better registration. I went a poor mans method to try and improve the fit of the wheel over the shaft.

I found a piece 1in wide of masking tape provided the desired improvement. Original washer shown in the picture. This also has an ID which is too sloppy and tries to ride up the shallow registration shoulder.


The wheel mounted, just need to cut off the excess masking tape.


I may make a custom washer now that I have some aluminium of relevant diameter, but the masking tape made a worthwhile big improvement.

Interested in the PDF too when you have it done. I have a friend just getting into turning but he is on a very limited budget and does his freehand but wants a system to help save him from grinding too much steel!

Thanks
