Looking for feedback on these high-temp (nylon?) adhesive knot filling systems. Both systems look like they are primarily designed for working in the flat and come with aluminum iron and "mouse plane" Has anyone tried them on a bowl/lathe specific repair?

Both systems use a high wattage "hot glue" gun to apply the filler. Both systems offer multiple color options. Both are said to cut, sand, and finish like wood.

Rangate
Looks to be a high quality kit. Filler sticks are much more expensive at $65 / package.

Knottec
Similar quality kit to it's competitor and slightly less expensive. Filler sticks run about $15 / package.

I have not used either product.

 

Both look interesting. My first reaction was that there are limited "color" possibilities if they were to be used as a way to embellish/repair a turning. Epoxy/resin products can use a variety of ingredients to enhance the look/feel/color of a filled area. 

 

Just my 2¢

It gives me the impression that it is just colored glue sticks with a heat sink to cool it off and flatten it out.  Glue gun, a piece of aluminum and your wood chisels should work.

The filler sticks are made from polyamide nylon according to Gary, sales rep that I spoke to.  Hence the reason for a high temp gun.  Makes me think...melted nylon rope. 

 

He sent me a link to this short video.

No knowledge or experience of either, but thanks for the links and video Forty. Looks interesting. Hopefully I can recall this down the road when needed.

so melting down my coffee containers is passe?

I searched polyamide glue sticks and there are plenty of hits.  Says they are good to repair plastic and wood knots etc.  Sounds like something to look into.  Thanks for bringing this up.

I already have everything but the glue sticks.

Greetings fellow Woodworkers-

I have used the color hot glue sticks and what a disappointing waste of time. I received recommendation from a fellow woodworker to buy the Rangate Knot Filler.
I purchased the Rangate knot filler kit with temp control without any research. I must admit I was amazed of the quality of packaging, appearance of the kit, clear concise instructions, ease of use with no mess, durability to sand and accept a finish. Using the Rangate poly ( plastic) sticks exceeds all of my expectations. Do not use the glue-- it will fail and the craftsman (you) will take the hit. The poly sticks work wonderful, the trick is cleaning the void and setting the correct temp. Do a practice run. Please be advised this is not food safe. If you want food safe, pick your epoxy wisely as they are not all the same, ( I'm happy to recommend one that is food safe) I pride my shop on using the best materials and equipment I can find. Finding the best isn't always about spending more money, only 80% of the time does money drives the best. I've always said when price factors,

"It just stings once". Bottom line, this is without question the Festool of heat guns. You will not be disappointed!

Happy Woodworking!
