Gday Nigel, this has been extremely helpful, I’ll have to get some, thinking back I have had small jobs where work holding has been a problem, this could be the answer, thanks for sharing this, much appreciated, cheers Matty
Hi Nigel, good video. Thanks. Like owlman I wondered if the part just got too warm and it failed from the glue softening. Maybe with a cooling air stream directed at the cut would help in this regard. Certainly something to keep in mind for those impossible to clamp situations. I've used hot melt glue from a gun in wood before and then released it with a heat gun after machining but never tried it with metal in the mill. Enjoying the loco build. Can't wait to see it in steam.
Excellent demonstration Nigel and really good product. Reminds me of when I used double sided tape many years ago to stick some thin brass plate to the top of the vice to fly cut it, it was nowhere near as solid as this looks! What is the cleanup like post separation? Is the adhesive soluble with any chemicals? Great video. Cheers, Jon
Hi Jon Yeah, it's seem quite solid, I think I trust it more than super glue, time will tell. I'm told that isopropyl alcohol will devolve the glue, I'm sure acetone or similar would too but not tried it. Scraping it off and emery clothing didn't take long. Thanks for watching, much appreciated.
So far it seems to work pretty well, I think you have to make sure the full mass of the material in both parts gets up to temperature, the hot plate seems a good way to go, heat gently, get up to temp, cool gently. Cheers for watching!
I was cringing when you started to cut the slot , I thought to myself Nigel really doesn’t like that cutter does he 😂 . I definitely will be looking for some of that hot melt glue sheet , I can also use it for gluing metal face plates on metal enclosures on some of my electronic projects .
Hi Robert, no the machining process does did not heat the job up any where near enough to effect the strength of the glue, I think it just has it's limits like most things. Cheers Nigel
The bond to the metal failed, In both fails the glue stayed intact on the base plate, with none on the test part, maybe the part did not get hot enough? I think you have to make sure the full mass of the material all gets up to temperature, probably measuring the temperature as a check could help. Thanks for your interest.
@@GoCreatehms Interesting. I have never thought of using hot glue this way - I have always found it to be relatively brittle when used on anything hard (particularly plastics), I suspect it is designed for use with wood, card, paper and possibly fabric where it can get into the pores in the surface . Thanks for the video.
Seems to work well Nigel... definitely food for thought...
Something I would never have thought of. Good to see both uses and limitations
Cheers Lewis.

Really nice close up shots. Good video.
Thank you that was something I've never heard of and very interesting.
Very impressive and I would never have dreamt of using that method, live and learn, thanks.
And I was impressed watching your eccentric rods build.

hi gchms
great tip that, i'm going to order some to have on stock, for those tricky jobs
stay safe

Very interesting. Would you prefer the glue film over superglue?
Time will tell but probably yes, I think I feel a little more confident with the hot glue film, but both are pretty good.
Did the metal warm up while while cutting? Does that make it loose it’s strength a little. Very handy to use :)

Cyanoacrylate glue, aka super glue, also works well. I have used both glue film and Cyanoacrylate with success
nice
Was the part hot from milling when the glue released during the first test or did the bond to the metal actually fail?

Nice demo, but I cringed when you ran your fingers along sharp edges & through the swarf.
Yeah, I ive dangerously, should be more careful. Thanks for watching!
