My seller refused to answer on email if the epoxy is "ok" if the pumps are mounted on the cans/containers and left there.
I guess many of you have experience with this - first hand - any recommendations would be highly appreciated.

For small work I'm still using Tiger Products bottles since I'm not comfortable to mount the pumps just to mix these small portions. But since I have these West products on the shelf I though it would be worth using it for ring work as well (even if I have no problems with the 30min Tiger glue). It's not worth the money if they stay on the shelf ....:o

I read a lot of you use scales for smaller amounts - which I guess is the way to go in stead of the pumps - or ?

Have a great weekend.

I never used pumps at all. I put some resin and hardener in squeeze bottles. I mix it by weight. First the resin in a small cup then I drip in the hardener a drop at a time till the weight is correct. The pumps not only are not all that accurate, but you waste a lot of material. They may be good if you are mixing a lot of resin like when you fiberglass a deck but not for very small amounts such as 5 grams or even less.

For example, suppose I want a small amount of glue and the ratio is 3 to 1. I can put say 1 1/2 grams of resin on the scale then drip in a 1/2 gram or hardener or 4 1/2 grams of resin drip in 1 1/2 grams of hardener and I have a perfect mix.

This is by far the best way to do it...............

I have left the pumps in the cans and on the shelf for 18 months with no problems. But I still weigh it on a gram scale.

The mix ratio of 105/207 is 3 to 1 by volume and 3.5 to 1 by weight.

Thanks guys.
I guess the pumps was a waist of time, until I buy a boat or something...
The scales is ready to go so I'll get something small enough to mix it in now.
For clear I have use larger syringes to mix clear but I'll go for the weight as recommended.

Have a nice saturday and happy cue building:-)

Waste of time.
Put them on squeeze bottles and store the cans in a cool dry place.
For mixing, weigh the hardener then add epoxy for total weight.
For 3.5 to 1 ratio, multiply the hardener by 4.5.
1 gram of hardener will need t 4.5 grams of total weight.
For 5 to 1, multiply by 6.
1 gram of hardener will need 6 grams of total weight with the epoxy.
 
Thanks Joey and Royce.

Joey, your numbers helps a lot,
Royce, you know your gadgets ;-) Looks super nice, would have to read up on it though. Did you get my email by the way.

No wonder the sales man did not respond at all. I guess he's happy I'll spend way to mutch just for some small work..

Have a good one both of you.

I buy the 3 oz bathroom paper dixie cups, $2.00 for 250.... and a box of 1000 craft or popsicle sticks for $5.00.

Easy to mix and weigh on a little scale.

The small plastic squeeze bottles are also a great idea.

Kim
 
Thx Kim,

I'll see if I can get them over in my end, it's not always that easy to get the same stuff as you guys.

For a 3.5:1 ratio, 3.5g should be mixed with 1g, giving a total of 4.5g of mixture.

Paul, you're making it more complicated and you're wasting more plastic mixing cups.
Use one cup.
Put in the hardener first , then multiply it by 4.5 for total weight.
1 gram of hardener ? Put in epoxy until you get 4.5.

.5 of hardener, gets you 2.25 total weight.

Kent,

I know most don't use as much epoxy as we do, but I know several cue makers using these. I resisted buying one for quite a while, but am glad I did. We can mix less than a 1/2 ounce, or up to as much as I want and the mix is dead on.

We used to have a rule that when we mixed epoxy to glue something up, we always kept the cup until it cured. If it didn't, we knew we had to go back and redo that step. This kept us from having product go out with bad glue joints. Now, even though we still keep the cup out of habit, we know it will all be good.

I did get your email, but I've been a little backed up on emails. I direct so much through Shane now that I spend much more time in the shop. I'll get back to you tomorrow though, and we'll get you taken care of. Being in the shop more lets me work on our equipment, process and production as well as work on some new ideas for products.

thanks

Do you have a ratio for the 105/205 or is it the same as the 207 ?
 
Actually, the mix ratio for 105/207 is 3.7:1 by weight.

I find it easier to place my cup on the scale & zero it.
- Add what looks to be a ballpark quantity of resin & note the weight.
- Multiply the weight by 1.37.
- Add hardener until you get to that number.

Also, see HERE

Thanks a bunch Kim and Bob.

I ordered a lit from West so it would be interesting to start experimenting with this. I have a Asian cue donated by the owner due to internal buzz in the A joint. Would chop it at the A and see if a recore and new tenon glued with West would cure it :-)

Royce- I totally understand. Having more time in the work shop is what we all want. Just drop me some words when time permits.

Dixie cup and a scale. I do use the pumps but only to make it easier to get it in the cup. The only time I use a full pump is when I am doing veneer stacks and need a lot of glue. Even then I verify the mix on a scale.

Oh, and I don't throw away the cup until the next day. If it does not kick off I want to know before the cue develops issues.
