I don't know if anyone still wants this... When I did a quick search for it, I found this thread, and I figured there are others looking for it also. So, For you reading enjoyment I present the B & I 6" Gem Maker Manual.

You can get it attached in this message, or if that doesn't still exist, find it here:

www.shimatzki.com/b&i-6inch-gem-maker.pdf

The above is my family website, so as long as I keep that going, you'll have access to it. (Slightly different name, but same file... just more web friendly)

Since The B & I Lapidary and Pottery Equipment is out of business, I will assume that there is no problems with it being reproduced in PDF Format here.
Anyone with information contrary to that, Please contact me to discuss it.

Enjoy
-Steve Shimatzki

PS.. Turned out a had a copy in the box of books that I got as a christmas present! How's that for fate!

I don't know if you still have the manual for the 6" gem maker. I just picked one up a couple of weeks ago. I can figure out most of the workings of this critter but would be nice to have a manual for it in any case. It just has the Craftsman label on the side and I did a search and turned up a Model 1401 Gem Maker by Sears. I just ordered blades for it. Already have polishing wheels and motor. Now just have to build platform and assemble. Any help would be appreciated.

10" Gem Maker Novice Questions
August 11, 2008 02:50AM
Well, I seem to have a common story. Yesterday I picked up a ten inch Gem Maker at a garage sale. Have the unit, original diamond wheel and cast iron lap plate. Missing the other wheels but the rest of the unit is all there. Picked up a motor and St. Vincent de Paul today and got it running. Cutting is very slow so I am thinking that this original blade is about shot. Took two hours to cut through a rock (not sure what rock it is but is grainy like marble) that is about 3/4 inch thick by 1 1/4 wide. I was running at second blade speed which I guess to be 800 RPM. Now running faster (I guess about 1,200 RPM) and seems to be cutting a little faster as well, but still, I think a new blade is in order. My questions --

Any recommendations for blades that you guys have had success with? Do I bite the bullet and pay $$$ for the Lortone blade or are there better choices for the money?

Other supplies - Where do you get parts and where do you get your polishing compounds?

Good books?

I have a manual and original sales brochure. Anyone want PDF of either?

You might just want to post them as an attachment to a message on this thread to make them more readily available. There does seem to be an interest in them. (if they are over 1 meg let me know)

Hello All
I also am in need of an operators manual for a 10" B&I Gem Maker. Please help if you can. I'm also interested in a 10 " Lap wheel for the same. Are there any parts out there? Are there any facet heads floating around?
Thanks in advance!

Dumb question Larry, but did your unit have the water drip cup...if you haven't used a unit before, you might not know about the need for lubrication and wetting of the cutting edge of the diamond blade. If you do and you have had a fairly steady flow of water onto the blade and the cutting is still slow, then it may be either the blade has lost it's embedded diamonds, or that the material you are cutting is quite hard.. Mine had a weighted assembly with a stone vise, which pulled the stone against the blade...does yours...and if so, is the weight on the end heavy enough or are you doing this by hand?
Just a few thoughts ...

I am looking for an owners manual on the 6" B & I. I have been "googling" trying to learn more about this unit I recently obtained but haven't used yet. I changed the belt in it (BADLY needed) but don't know what other "maintenance" things I should do before using it. Also, do you have any idea what these go for these days.
Thanks

I don't know if people missed my post about 8 up, or if the attachment didn't work, but... Here's what your looking for, I've attached (again) the B&I manual for the 6". If someone has a manual for the 10" please feel free to post. In my experience, the 10" and the 6" are basically the same. The Facetting head I have seems to only be for the 6" and I have a 10", so I don't know if the manual for the 10" will cover anything different there.

Basically they are the same beast, just the 10" is wider. Concepts and uses are the same so the 6" manual is a great place to start.

As for location of replacement laps, I'd say Kingsley North: www.kingsleynorth.com But I'm biased because they are pretty close to me and shipping is fast. (one state north)

I've been using the following, I got an Inland 8" Master Lap for the base ($19.95). If you want to polish, use the same master lap with some 8" Ameritool flexable pads or similar. 1200Grit = $35, 3000Grit = $35 You could also get the flat diamond laps if you needed: 8" 100mesh Diamond disc (74.95) and 8" 600 mesh diamond disc ($49.95) and that covers your basic grinding. I have a regular highland park unit that I use for grinding and only use my B&I as a flat lap for final smoothing and polishes. This is all on my 10" B&I... You'll want to use smaller for the 6', and also these are suggestions for durability type use, you can use other products but in similar manners.

Actually, before I switched it over to Diamond, I had my "master laps" made from plywood that another Rock Club Member had previously made and gave to me when they heard I had it. I used those wood masters with foam circle and then a wet/dry silicaCarbide sanding paper. (sandwich the foam between the wood and the paper, use a little rubber cement to hold them together) That was VERY in expensise, and worked great. I made some awsome cabs on that. And I coiuld get the SilicaCarbide paper @ the local hardware store, nothing fancy other than it was wet/dry use so the paper held up. The only down side was the spead that the 600grit paper wore down to 1200grit... and my 1200 would ware down to about a 3000grit... So I kept having to re make the different laps. I even started putting foam on two sides and labeling the edges of the wood with dates so that I knew I had an "old" 600 and a "new" 600... if the 600 wasn't cutting right, I'd just flip to the "new" to save time and redo the lap at a later date. I would of kept using it this way, but I wanted to try the diamond approach for consistancy reasons.

Stephen,

Thanks for the download. My wife is an eBay seller (just a note to some posters: she's an honest seller) who buys at estate sales, auctions and thrifts. We picked up my Gem Maker up at an auction last spring along with an old trim saw and about 20lbs. of various rock and tumbled stone. She was looking into resale, but then saw my fascination and decided it would be good for me to have a hobby, lol. I won't go into how I've misused this thing with grinding discs not meant for it, but I've been trying to build up the cash to buy some good quality discs.

In looking into discs, I've seen the inexpensive adhesive backed discs that you apply to a master lap and of course the Inland diamond discs. Quite a price variation. I know that generally you get what you pay for. Which comes out cheaper in the long run.

Thanks

Rock Bear...

It really is a matter of work for you... You "invest" in a diamond lap (fexible on a master lap, etc...) and you have less work than if you use the "cheap" old school method of Silicon Carbide Grit paper over a plywood or wood master lap... The paper wears down fast and you are constantly regluing paper to your mast lap units... That results in more downtime and hassle and chance of errors. (torn paper, etc...) The diamond flex pads over a master lap will last much longer if properly cared for and such... Obviously there is a HUGE price difference, but then you have to put a price on your time. (Really, a B&I machine is 1/4 as usable as an arbor with 4 seperate wheels on it, but that is another story completely.)

Like I had stated, I started with the cheap method and gradualy moved to the the diamond once I knew more about what I was doing, etc... I still have all my old laps and paper, but haven't put one together in a long time. The nice thing about the cheap method is cost of errors. :) If I gouged a section of the Silicon Carbide Paper, no worries, just glue up a new one... If it was a Diamonda disc, ouch! Thats a $ mistake.

So, take this information for what it is worth, and apply it to your own situation.

My last piece of advice is always to find a rock club near you... The experience and hands on learning that you get from the "Ol' Timers" will be more valuable than re-inventing the "wheels"... Besides... Most have nice shops that save hundreds/thousands of Dollars in equipment cost of you buying it on your own.

Thanks for the help.

I was wondering if anyone had found a good source for a replacement 10 saw blade with the correct arbor size to fit the 10 inch gemmaker?

Where can I get rid of this - The Gem Maker has a 6" wheel (see pic). There is an electric motor with it but not mounted together. I have another piece of gem equiptment that has a brass looking disk on it with an electric motor mounted to spin it. I know nothing about this sort of stuff. Thank You in Advance, Dennis

I recently purchased one of these old 10 inch units. It appears to be in good repair except for a motor which I can pick up with no problem. However, I would be interested in getting an operating manual to go with it. Also a picture of the complete set up unit if available.
Thank you.
