rider Posted November 28, 2018 Report Share Posted November 28, 2018 Has anyone had success with any steel heel receiver fitting on Bomber TD 1 bindings? Thanks! Quote Link to comment Share on other sites More sharing options...
lowrider Posted November 30, 2018 Report Share Posted November 30, 2018 Hole centers are different but they can be slotted out . Same would apply to aluminum strip that screws go into and clamp down receiver. TD1's 5.5 cm TD2's & 3's 5 cm . Quote Link to comment Share on other sites More sharing options...
rider Posted December 1, 2018 Author Report Share Posted December 1, 2018 Thanks. Have you slotted some out? Does it go pretty smooth? Quote Link to comment Share on other sites More sharing options...
lowrider Posted December 2, 2018 Report Share Posted December 2, 2018 It's just nuts and bolts not rocket science ! A file a vise and if your lucky enough to have a small drill press it's a matter of how much time are you willing to invest ? Quote Link to comment Share on other sites More sharing options...

skrekk Posted December 12, 2018 Report Share Posted December 12, 2018 (edited) I'm using TD3 steel heel receivers very successfully on TD1 bindings, 5 years of daily carving during the ski season and I've had zero problems with them (and a huge improvement over the aluminum receivers). It's not the hole spacing that's the problem but the bolt size and the fact that the receiver needs to be shimmed up a bit to make the boot level so everything engages and releases properly. I used the smaller bolt size of the TD3 (6mm), a stainless nylock nut and stainless washer underneath the binding plate, and a short piece of heatshrink tubing around the bolt to (hopefully) protect the M8 threads in the plate. The bolts are labeled "A2-70 THE", so they're a marine grade stainless, M6 x 1mm x 25mm flat hex with a 90 degree shoulder angle, similar to a McMaster-Carr 93395A363. I'm not sure where I ordered mine from, maybe Fastenall. Another source is this: https://www.amazon.com/10-M6-Stainless-Countersunk-MonsterBolts/dp/B078YYDZ34?th=1 The shims are 1/8" aluminum stock with a hole drilled to allow the bolt to pass, and some super thin double-sided tape to hold them aligned to the plate. You can see them under each side of the receiver in the pics below. Edited December 12, 2018 by skrekk added link to bolts 1 Quote Link to comment Share on other sites More sharing options...
Corey Posted December 12, 2018 Report Share Posted December 12, 2018 Creative idea, shrekk! Looks good. 1 Quote Link to comment Share on other sites More sharing options...
skrekk Posted December 12, 2018 Report Share Posted December 12, 2018 One thing I worried about was that using a single M6 nylock nut on each bolt would be weaker than the 1/4" thread depth and M8 of the TD1 plate, but so far they've never broken or even loosened up at all on any of the boards I ride. 1 Quote Link to comment Share on other sites More sharing options...
skrekk Posted December 13, 2018 Report Share Posted December 13, 2018 (edited) I also considered but didn't try a thread reducer insert .....I was concerned that with an M8-M6 reducer there wouldn't be enough material to support the stress, especially going from a 1.25 pitch to a 1.0 pitch (which is why a standard helicoil insert can't be used). However I did find a source for these rather rare beasts, the Memfast p/n TCM6M8SCR3: http://www.memfast.co.uk/shop/vclose1.asp?prd=31737&cat=2250005134 If anyone tries it I'd like to hear if it works.

lowrider Posted December 13, 2018 Report Share Posted December 13, 2018 Still probably a good idea to put a nut under it even with the insert. 1 Quote Link to comment Share on other sites More sharing options...
skrekk Posted December 13, 2018 Report Share Posted December 13, 2018 (edited) That's a very good idea and it would eliminate the need for threadlock on the insert. I'll order some inserts and try them out. If nothing else the inserts will protect the base plate threads much better than the way I did it and minimize any movement in the heel receiver due to bolt stretch (because more of the bolt is engaged by threads).

rider Posted January 24, 2019 Author Report Share Posted January 24, 2019 This is great Skrekk! What is the approximate size of the aluminum strips? Do you think there is enough room to “double nut” with longer screws? Thanks Tom Quote Link to comment Share on other sites More sharing options...
skrekk Posted March 4, 2019 Report Share Posted March 4, 2019 Tom, sorry for the slow response. There's plenty of room to use 2 nuts. The aluminum shims are just 1/8" aluminum flat stock, the width and length aren't critical but mine are 3/4" by about 2-1/2", just long enough to fully support the heel receiver. https://www.menards.com/main/tools-hardware/sheet-metal-rods/hillman-reg-aluminum-solid-flat/11288/p-1444432415320.htm Ideally these would be made from something like stainless steel but I haven't had any corrosion issues using the dirt-cheap 6063-T5 aluminum stock.
