B&I mfg

I just recently got what looks to be like a 8 to 10 inch horizontal lap machine
at a yard sale. On one side it has a metal stamp that says Gem Maker by
B&I MFG. of Burlington Wis. The motor is shot but every thing else seems to
move freely. I was woundering if anyone out there might be familiar with this
brand and if the Co. is still around. You now like for spare parts and a manual.

Manny:
This was once a very common machine sold through Sears & Roebuck; I believe it should only be a 6 inch diameter machine. If the motor is shot, you can get a used motor from an appliance repair shop, one from a washing machine for example. You will need a 1750 RPM motor (fairly standard) at a horsepower between 1/4 and 1/3 HP, plus one that operates on standard 120 Volts. This should be easy to get, as they are fairly common. The pulley on the motor should be about 2 to 2-1/2 inches in diameter, but you may want to check John Sinkankas' book on Gem Cutting for rim speeds & pulley diameters. I have one of these old units still, which is invaluable for polishing as the horizontal wheel will hold wet polishing compounds far better than those with vertical wheels. Also, you can unscrew the "nut" on the bottom of the shaft and add grease to the receptacle, in case it has not been done in a while.

Does anyone know what happened to B&I?

What years were they around?

Thank you!

B&I gem makers were around in the late 60's to the early 70's.I have several of these machines in both 6" and 10".I have manuals for both.If you are interested in a copy email me using the above subject title.But I need to know if it is the 6 or 10".Take a measurment from the center of the arbor where the wheels go on to the shortest distance to the outer case.

George,
If you have a manual for a 10" B&I Gem Maker, I would appreciate it. I found one at a garage sale many years ago and have made some use of it but not as much as I would have liked. My kids are now starting to collect rocks and have become interested in it. A manual would be much appreciated.
Thanks,

George, could I also get a copy of the lap machine (6").
I recently began teaching geology at a high school and they have a lap machine in poor condition. I have it up and running, but there are some parts that I can't seem to figure out if they belong to the unit or not. the manual would help alot so that the students can use it to polish up the rocks and mineral that they collect, cut and put on display.

Thank you for your time and help.

Hi George,
In your post you say you have several of the machines in 6" and 10" and the manuals. I just bought a Craftsman on Ebay. I think it is a 10". There is a rusty 1/4" thick 10" diameter steel plate on the shaft currently. The shaft does turn freely and without any noticable wobble. The center to closest side measurement is just over 5 1/2". If you have the actual machines are any of them for sale or available for parts? I need the manual also but there are some missing or badly pitted parts that I'd like to replace. Any assistance would be appreciated.
Thanks,
Dick

I was recently given a 10" B&I Gem Maker. It still runs ok and even has the facetor attachment and the instructions. It doesn't look like any dops came with it though... and they would have to be VERY thin to fit in the armature. Does this mesh with other folks experience? Also, the instructions indicate that the facetor head can be placed in the same slot used for the sawblade attachment... but I'm still not sure about that.

Any feedback is appreciated.

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.

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?

Ray Hill October 06, 2008 09:03AM
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 ...

Stephen Shimatzki February 12, 2009 03:07PM
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.

Rock Bear February 12, 2009 03:48PM
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

Stephen Shimatzki March 22, 2009 02:23PM
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.

A while ago I purchased a 10" Craftsman B&I Gem Maker at a flea market. It is mounted in a wood cabinet along with the motor and some storage space - all hooked up and runs like a champ! Not bad for $25 bucks. It just has one plate and no other attachments I did however find a water cup for it and got everything all cleaned up. I can figure how it works although any leads on a manual would be fantastic. Even more so as just this week I found another 10" unit (with most of the attachments) and I'm in the process of getting it cleaned up.

It looks like this is the place (the only one I have found) that folks talk about these older units. And again any leads on an instruction booklet or manual would be great.

Thanks,

Pete

Hi Everyone, I have an instruction manual for a 10 in B& I Gem Maker. I am in Canada, but for the cost of photocopying and mailing I'll gladly send it on. I have 6 printed pages of instructions and a further 6 full size colour photos on how to set it up. Let me know, you can reach me by my email cmacneil@bellaliant.net Thanks

I bought the 10" model 1422 and have the papers but need photos of the thing assemble and setup with the motor attached. Does anyone have some to share? Thanks so much.

If you still have a manual for the 6" B&J gem maker, I would really appreciate a copy. Please let me know.

I recently acquired a 6 inch Gem Maker and am in desperate need of a manual as several parts are missing. If anyone has one, I would be glad to pay you for a Xerox copy. Please let me know how much.

Thanks for your help.

Hi All,
I have the 6" gem maker with the faceting head. Is there any instructions on how to set this up and the process used on this particular machine? I have the instructions I downloaded from this forum, there are at least 4 or 5 postings of the PDF so anyone can download them. But not one of those pdf's contains anything about the faceting attachment and how its set up or used. It appears I will have to make some modifications to the faceting head as the diameter of the dop stick holder is not standard, its only a slight amount and I hope I don't destroy the whole unit. I have a very nice drill press that I hope will do a perfect job. Any help with the setup and use of the faceting unit would be greatly appreciated.

Thanks,
Joel

If your blade is not cutting very fast it may be "glazed over", meaning the metal the diamonds are embedded in has melted over them due to heat build up over time. You can "dress" the blade by making several cuts into silicon carbide blocks or old silicon carbide grinding wheels to remove the built up metal and expose fresh diamonds.

Cheers!!!
