Lyman 1200 Bowl Broke


January 26, 2013, 04:19 PM
I just cracked my tumbler bowl by dropping a drill on it. Duct tape will facilitate a temporary fix but I'm sure it won't last. I can get a replacement bowl but what fun would that be!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Anyone ever make one or have any ideas I could use in wasting some time trying to do so?????

the red-neck in me says "J-B Weld " :D

If you use JB Weld, you will need to use a piece of screen or fiberglass mesh for reinforcement. Duct tape doesn't have to be considered a temporary fix.

For a more permanent fix: Hold it together and put a few drops of acetone in the seam with an eye dropper. It'll get sucked right in and fuse the crack together. It'll hold itself after only 20 seconds or so. But this weld is prone to cracking, not good for a tumbler bowl. So follow by either:

1. Rough out the outside of the bowl with some 60 grit sandpaper, spread some JB over it, and then lay a strip of autobody fiberglass cloth over it. Spread more JB over the top of the cloth, then put a strip of packing tape over that to push the epoxy into the cloth and to smooth the surface. Remove the packing tape after the JB cures.

or 2. Use a soldering iron to fuse the bowl together by zigzagging over the seam on the outside of the bowl.

or 3: Rough up both sides of the bowl with 60 grit sandpaper. Drill a bunch of small holes along each side of the crack. Sew it up with some steel wire. Then cover with epoxy and sand smooth.

I bet duct tape holds for a long time. I wouldn't worry too much.

use two-part epoxy made for bonding plastic. it's the same stuff auto body shops use to patch plastic bumper covers.

A tip to use is to drill a small hole just below end of the crack to stop it from spreading before the repair or it will flex with the vibrations and then the crack will spread more. Then use whatever method you choose to fix it. I would keep the repair on the outside of the bowl or the media will eventually eat it away. If you do add material add some to the opposite side in the same approximate amount to balance the bowl or the shock mount system will wear out sooner.

I personally would drill the hole as mentioned superglue the split and run a small bead of silicone along the seam on the outside then add one to the opposite side of the bowl of the same length.

would one of those big epoxy 'patches' not sure the exact name work - they have them at Menards near the glue and tape section

Seems like an awful lot of work when you can get a new bowl

Very true!!
But a new bowl is $18.00 plus shipping and about a week or more away for many of us!!!
Eventually I will replace it but I have much of the stuff mentioned here and it will probably dry up, get lost or taken by my kids before I use it for anything else. The main reason to attempt a repair like this is the learning experience and I learn more from what doesn't work than what does. I have always enjoyed working with my hands and taken broken stuff which does not work and making it work ( or poorly made stuff and improving it) at least for awhile. By doing this I have developed skills which enable me to earn a very good living!! Where I live there was a MASSIVE storm last summer and the electricity was gone for several days and everyone realized without electricity their cars didn't work (no gaspumps) along with a whole lot of other things. It pointed out that hard times often occur in a heartbeat and without warning. My point is developing and sharpening your skills on seemingly dumb stuff today can payoff big when you least expect - like when you have no choice but to make do with what is on hand.

I have several very specific glues at work for different types of plastic. Plexiglass, lexan, etc. but they cost 50 bucks per pint and you have to use exact formula for type. I also have a sonic welder that uses little sticks of filler.material to weld plastic. While mine is a commercial U.S. version, import copies can be had on eBay for cheap. Drill hole in end of crack to keep it from continuing, duct tape well and run. If you use silicon it will take 24 hours to dry and does not have great mending ability. It is a filler. Plastic bumper repair kit price at body body shop about buys you new bowl. Run it with the tape while you wait on a new bowl.

Epoxy/JB Weld/Brownell's Accraglas Gel (good, better, best, IMHO) and fiberglass cloth. You should add the rough approximate in weight to the opposite side, but I doubt you'll reach critical mass if you don't.

Gorilla tape, now that stuff is permanent.

I have the same model tumbler and the asymmetrical weights that produce the vibration broke and let loose from the shaft. This was 7 or 8 years ago.

JB Weld to the rescue! I gobbed it on there (technical term) and it hasn't moved since. Works good. Love that stuff.

Call Lyman customer service, I'm sure they'd be friendly and willing to sell you a new bowl for the price of an entire new machine. Let us know about your experience with their customer service and if you still have all your fingers when you hang up.

+1 on Gorilla tape. It's a bit pricey but can tape a greased pig to an icesickle with it.
