| Post subject: | Tuck Shrink tool |
Made a tuck shrink tool out of some HF nail sets and an old Volvo push-rod. Just peeled the rubberized coating off the punches and welded 'em up. It should help me gather and form body panels over the rounded corners of the boot. Attachment: IMG_0473-1.jpg Total cost $4 and I even got an extra nail set out of the deal. Here's how it is used: https://garage.eastwood.com/tech-articl ... ck-shrink/ |

Interesting tool. And video link. I may have to make one for myself Such a tool for this application is unnecessary IMO. Forming and shrinking using the tube as a form, while occasional annealing if necessary, is pretty easy. Gentle steps rather than big steps helped me. |

Forming and shrinking using the tube as a form, while occasional annealing if necessary, is pretty easy. Gentle steps rather than big steps helped me. On my first boot corner I still have some big gathers to anneal/beat out. I think the second corner should go easier by first setting up the metal gathers with the fork. Agreed it's not necessary, but the fork should help make for smaller, more consistent gathers and speed the proess. FastG wrote: Where's my tucking fork:)

FastG wrote: I found my tucking fork. Lovely vintage fork, Graham! I like how the gap between the tines stays close along its length. I suspect this would give a tighter tuck  I may do some blacksmithing to "adjust" my gap, or weld-up another fork with the handle-end of the legs spread to make the tine-gap consistent. |

Sooooo Of course I want one of these cause you have one. So I went to Amazon and typed in 'tuck fork', of course the search came up zilch. But I did receive an Amazon education, it suggested "tuck underwear trans", there were all kinds of tuck ginch (Noun. ginch. (Canada, Alberta and British Columbia, slang) Underwear, especially men's briefs.) to be bought, made me shiver............... |

Dagger tools sells them I made my own when i had to form the flange in my trunk opening. The flange caused the body to flatten. Fixed by tuck shrinking then hammer/dolly the tucks. Annealing helps a lot. Look up Wray Schelins Proshaper video on youtube. He shows several easy, effective and cheap methods to shrink metal. |

Made Tucking Fork version 2. Same HF $4 nail sets, just laid out differently. Not nearly as elegant as Graham's vintage fork, but should work better than my version 1. Attachment: P1015067-1.jpg The spacing between the tines was set with a piece of 16g steel while welding, but the gap tightened when the welds cooled. Probably should have use a 14g spacer. Should still work with 0.50 aluminum sheet before it fattens up during the shrink process. The sides should get some bracing to keep them from twisting while vigorously tucking. |

Nice, Tom. Practically a Snap-On in terms of appearance. Do you think that one tack weld will do it? I'd be tempted to add a little bead myself. Cheers |

Agreed, it needs some beefing up. With enough torque applied, the legs can twist, "walking" the tines around that lower weld. The legs are a little far apart to get a bead long enough to be effective. Given their separation, welding plating across/between the legs should provide enough strength.

Tucking fork version 2 got beefed up with a side plate to keep the tines from "walking" when torque is applied. The gap was also increased slightly with a sanding belt. Works better now. Total cost $4. Attachment: PC105086-1.jpg Another type of tucking tool is made by modifying channel-lock pliers. Ted Atkins sent me this picture of a one he dug out of his tool box. Attachment: Vintage tucking tool.jpg So I spent another $4 on a pair of cheap channel-lock pliers (hidden on the bottom shelf at HD), cut up some 1/4" rod and fired up the welder. Here's the result: Attachment: PC105089-1.jpg The corrugated strip of aluminum in the background was a tucking test piece (say that real fast  ) Both tools have their place and work well. Next step is to use them to start the shrinking of my second boot corner.

Tom - an oak "slapper" is a great way to flatten the tucks and finish the metal without marking or re-stretching. I made a few from a piece of wood from a pallet. In UK they call them flippers...apparently over there a "slapper" is a "loose woman" https://www.instructables.com/id/Autobody-Wood-Slapper/ |

If you are working with aluminum, and need a smooth mar free surface, cover the slapper's working surface with leather. You can never have to many slappers with different contours. Davew |

I'd love to do something like that someday.https://www.instructables.com/id/Autobody-Wood-Slapper/ davew wrote: If you are working with aluminum, and need a smooth mar free surface, cover the slapper's working surface with leather. You can never have to many slappers with different contours. Thanks, Dave, that sent me off to the leather shop. I could have bought belt blanks of various widths but chose to go with a piece of scrap leather @ $4 a lb. Plenty left for more slappers (not the UK kind. )After rummaging around in my lumber pile, I came up with a 30" piece of CVG Doug Fir (worth its weight in gold.) I was holding it back for a fitting project, but what could be better than making it into tools.  So starting here: Attachment: PC125090-1.jpg I ended up with this a couple of hours later: Attachment: PC125091-1.jpg Which was so much fun on a rainy day I did it again: Attachment: PC125092-1.jpg Now off to flatten some tucks! |
